CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 438,459, filed January 11, 2023, U.S. Provisional Patent Application No. 63 / 438,454, filed January 11, 2023, and U.S. Provisional Patent Application No. 63 / 438,467, filed January 11, 2023. Additionally, this application is a continuation-in-part of International Patent Application No. PCT / US / 2023 / 010581, filed January 11, 2023, which claims the benefit of U.S. Provisional Patent Application No. 63 / 298,522, filed January 11, 2022. The entire contents of each of these applications are incorporated herein by reference in their entirety. [Technical Field]

[0002] The present disclosure relates generally to a container for fluids. More particularly, the present disclosure relates to a container having a closure cap. [Background technology]

[0003] Fluid containers are well known for containing and dispensing fluids, such as personal care products, condiments, and other foods and / or beverages. To facilitate dispensing of the container's contents, these bottles often include a closure cap having a flip-top lid and a base with an opening. Additionally, tamper-evident and package integrity features may be incorporated into such packages to ensure product or food safety.

[0004] For example, some fluid containers include a thin liner sealed to the neck of the container bottle. Depending on the closure cap configuration, this liner can provide a tamper-evident indicator and help retain and maintain the freshness of the product within the bottle. In such configurations, consumers remove the liner from the bottle by twisting or otherwise removing the flip-top closure cap from the bottle neck. The liner is typically discarded (as such small components are generally difficult to recycle). Not only does this packaging generate waste, but consumers often find liner removal to be a time-consuming and tedious task. Removing the liner can require fine motor skills and manual dexterity, so consumers with limited manual dexterity may have difficulty removing the liner or unscrewing the closure cap. Furthermore, determining whether a bottle has been tampered with typically requires visual inspection of the liner. Because the liner is located under the closure cap, this inspection typically requires removal of the closure cap. Therefore, if one wants to be sure that the tamper-evident feature has not been removed, the closure cap must be removed before purchasing the container bottle.

[0005] In other fluid containers, closure caps are provided with tear strips that can be torn or broken away from a portion of the closure cap prior to initial opening, allowing the consumer to open the closure cap after removing the tear strip. Similar to bottle liners, these tear strips are typically completely removed from the closure cap and discarded due to their small size, which makes them difficult to recycle. For example, they are typically too small to carry labels indicating the type of plastic from which they are made. Similar to the use of liners, removing tear strips can require fine motor skills and manual dexterity, and consumers with limited manual dexterity may have difficulty removing tear strips.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] Elements in the figures are illustrated for simplicity and clarity and are not necessarily drawn to scale. For example, the size and / or relative location of some elements in the figures may be exaggerated relative to other elements to improve understanding of various embodiments of the present disclosure. Also, well-known common elements that are useful or necessary in commercially viable embodiments may be omitted so as to show various embodiments of the present disclosure without interfering with the illustration. Certain acts and / or steps may be described or illustrated in a particular order, although this specificity with respect to the order is not necessarily required. Terms and phrases used herein have the ordinary technical meanings ascribed to these terms and phrases by those of ordinary skill in the art, unless otherwise expressly stated.

[0009] The systems, devices, and methods described herein are useful for dispensing fluids from bottles containing consumables or food products, such as condiments or beverages. In some embodiments, the bottle includes a closure cap, the closure cap including a flip-top lid, a base, and a tamper-evident structure or package integrity feature configured to indicate whether the closure cap has been previously opened. In some configurations, a recess is included in a portion of the closure cap that allows a user to manually open the flip-top lid using leverage. A breakable member and / or a movable ring can be used as a tamper-evident indicator. In one aspect, the breakable member is broken or the movable ring is moved from a first position to a second position upon initial opening. When the breakable member is broken / torn or the movable ring is partially moved toward the fixed second position, the broken breakable member and / or the movable ring can provide a tactile tamper-evident indication. That is, after initial opening, a consumer or user can visually or tactilely determine that the closure cap has been previously opened. This is evidenced by the breakable member being severed and / or the movable ring being moved from the first configuration.

[0010] Previous solutions (such as the tearable strips and seal liners mentioned above) included a tamper-evident structure separate from the container bottle or closure cap. According to the present disclosure, the tamper-evident structure can be incorporated into the container bottle itself, providing a container bottle with fewer parts. The closure cap of the present disclosure can make the entire closure cap, including the tamper-evident structure, recyclable.

[0011] Thus, compared to traditional tamper-evident options, the tamper-evident structures or package integrity features described herein provide an easily identifiable visual or tactile tamper-evident indication that does not require the consumer to remove the cap from the bottle. Additionally, the present disclosure allows the tamper-evident structures of the closure cap to remain attached or fixed to a portion of the closure cap, thereby increasing the likelihood that a greater portion of the closure cap will be recycled. The solutions and structures described herein may also be applied to other closure caps, such as those described in International Patent Application No. PCT / US2023 / 010581 (filed January 11, 2023), which is incorporated herein by reference in its entirety.

[0012] FIG. 1A is a perspective view of a capped bottle, according to some embodiments. FIG. 1B is a perspective view of a closure cap 1018″ that can be used with bottles 12 of different configurations, according to some embodiments. Additionally, some bottles 12 include neck structures that prevent the cap from being easily manually removed from the bottle, as described in International Patent Application No. PCT / US2020 / 039387 (filed June 24, 2020), which is also incorporated herein by reference in its entirety.

[0013] FIG. 1A shows a packaged food product including a bottle 10 containing a fluid product 5, such as ketchup, mayonnaise, barbecue sauce, mustard, or other similar fluid food product.

[0014] In some embodiments, the bottle 10 includes a closure cap 1018 that is attached to the container body 12 by internal threads of the closure cap 1018 engaging external threads 16, 16″ (shown in FIG. 1B ) of the container body 12. As described below, the closure caps described herein can be incorporated into a variety of packaging configurations. FIG. 1A shows the bottle in an upright position (i.e., with the closure cap 1018 positioned generally above the container body 12). The present disclosure also contemplates storage of the bottle 10 in an inverted position with the closure cap 1018 positioned generally below the container body 12. In this inverted position, the container body 12 can rest on the closure cap 1018. Thus, during storage and / or dispensing, the bottle 10 can be positioned with the closure cap 1018 positioned generally above or below the container body 12.

[0015] The bottle 10 can contain a variety of fluids, but as an example, the dispensing bottle 10 has a container body 12 that contains a thixotropic fluid (e.g., a seasoning), and the neck of the container body is provided with a threaded portion (threads) that engages with the threaded portion (threads) of the closure cap 1018.

[0016] Figure 2 is a perspective view illustrating an initial open configuration of a closure cap 1018 according to some embodiments. Figure 3 is a perspective view illustrating an initial closed configuration of a closure cap 1018 according to some embodiments. The closure cap 1018 includes a base 1020, a flip-top lid 1022, an extending tab 1085, and one or more breakable members 1025.

[0017] The flip-top lid 1022 may be hingedly connected to the base 1020. For example, the flip-top lid 1022 may be coupled to the base 1020 via a hinge 1019 such that the flip-top lid 1022 can pivot about the hinge 1019 between an open position shown in FIG. 2 and a closed position shown in FIG. 3. In the closed position, the flip-top lid 1022 and the base 1020 collectively form a recess 1070 in the outer wall 1098 of the closure cap 1018. The recess 1070 generally has a mouth shape and may have a mouth-shaped opening. In some embodiments, the recess 1070 may be located along a portion of a side of the closure cap 1018 in the space between the flip-top lid 1022 and the base 1020. The recess 1070 may be located on the opposite side from the hinge 1019.

[0018] To open the closure cap 1018, a user can move or pivot the flip-top lid 1022 from a closed position, as shown in FIG. 3 , to an open position, as shown in FIG. 6 , described below. The recess 1070 provides a gripping area where a user can apply force or pressure to move the flip-top lid 1022 from the closed position to the open position. In use, a user or consumer can apply force or pressure (e.g., with a thumb) to the flip-top lid 1022. This force or pressure can be applied, such as by the user's extremities, or can be applied from an external source, such as an implement or other tool. Sufficient force or pressure can be applied to rotate / pivot or move the flip-top lid 1022 from the closed position to the open position.

[0019] In some embodiments, the base 1020 includes a central portion 1030 and a substantially flat portion 1062, with an opening 1034 extending through the central portion 1030. The substantially flat portion 1062 and the lower surface 1074 of the recess 1070 (i.e., the recess-forming surface 1074 of the base 1020) extend around the periphery of the central portion 1030. The circumferential side of the base 1020 includes a circumferential shelf 1064, such that the base 1020 has a recessed side 1053 from the side wall 1098 of the closure cap 1018. The recessed side 1053 extends around the periphery of the substantially flat portion 1062. The base 1020 includes one or more base steps 1054 near the top of the recessed side 1053, below which the recess is formed. In some embodiments, the base 1020 includes a pair of base steps 1054, one located on one side of the recess 1070 (e.g., the left side of the recess 1070) and the other located on the other side of the recess 1070 (e.g., the right side of the recess 1070).

[0020] In some embodiments, the base 1020 has a receiving element 1088 on the recessed surface 1074. In one aspect, the receiving element 1088 is disposed within the recess 1070 when the flip-top lid 1022 is in the closed position.

[0021] 2, the flip-top lid 1022 may have an internal protrusion 1090 on its underside. The internal protrusion 1090 may be configured to block the opening 1034 in the base 1020 when the flip-top lid 1022 is in the initial closed configuration. The flip-top lid 1022 may include one or more lid steps 1052 on the inner surface of the sidewall adjacent the bottom end 1023 of the flip-top lid 1022. In some embodiments, the flip-top lid 1022 may have a pair of opposing lid steps 1052. The lid steps 1052 may be configured to rest in recesses formed below the base steps 1054 of the base 1020 when the flip-top lid 1022 is in the initial closed configuration.

[0022] The closure cap 1018 may further include an inset wall 1091. In one embodiment, the inset wall 1091 is located inward from the outer or side wall of the flip-top lid 1022 and extends from the lower or inner surface of the top wall of the flip-top lid 1022. The inset wall 1091 may be spaced a predetermined distance from the outer wall (e.g., the side wall) of the closure cap 1018. When the flip-top lid 1022 is in the closed position, the inset wall 1091 may be positioned approximately vertically within the recess 1070 and extend from the flip-top lid 1022 to the base 1020. The flip-top lid 1022 may have a headspace or cavity 1092 between the side wall and the inset wall 1091.

[0023] The closure cap 1018 may further include an extending tab 1085 extending from the inset wall 1091 of the flip-top lid 1022. The extending tab 1085 may include a flange 1083 extending from the inset wall 1091 and an engaging protrusion 1082 extending from the flange 1083. In some embodiments, the inset wall 1091 may have a notch 1091′ (see FIG. 6 ) in the center of its edge. The flange 1083 may be disposed in the notch 1091′, and the end of the flange 1083 and the end of the inset wall 1091 on the side of the notch 1091′ may extend continuously. In some embodiments, the flange 1083 is slightly smaller than the notch 1091′ of the inset wall 1091, and there may be a small gap between the inset wall 1091 and the flange 1083. In some embodiments, the engagement projection 1082 may extend from the flange 1083 in approximately the same direction as the flange 1083 extends from the inset wall 1091, such that the extending tab 1085 is generally aligned with the inset wall 1091 in both the initial open and closed configurations. In some embodiments, the flange 1083 of the extending tab 1085 may have a width that is greater than the width of the receiving element 1088 of the base 1020.

[0024] As an example, the engagement protrusion 1082 may be configured to easily press into the receiving element 1088 of the base 1020 and not be pulled out or removed therefrom. When the flip-top lid 1022 is moved from the initial open position ( FIG. 2 ) to the initial closed configuration ( FIG. 3 ), the engagement protrusion 1082 enters the receiving element 1088. The engagement protrusion may include, for example, a locking tab, a hook-like member, a snap hook-like protrusion, or other structure for securely coupling the engagement protrusion 1082 to the receiving element 1088. The receiving element 1088 may include, for example, a receiving opening, a channel, a cup, a housing, a gripping arm, or other structure for securely holding the engagement protrusion 1082. As an example, the engagement protrusion 1082 is aligned with the receiving element 1088 when pressed into the receiving element 1088. The receiving element 1088 is depicted here as a rectangular opening as shown in FIG. 2 but may have different shapes, such as an elongated linear element or a discrete cup.

[0025] In some embodiments, the engagement protrusion 1082 may be generally arrowhead shaped, as shown in Figures 2 and 3. For example, as shown in Figure 5, the engagement protrusion 1082 may have an elongated portion 1082a and a locking tab or arrowhead portion 1082b disposed at the end of the elongated portion 1082a. While the end of the engagement protrusion 1082 in Figure 2 is depicted as a triangular locking tab, the end shape may also be diamond or spade shaped.

[0026] In some embodiments, the flip-top lid 1022 may include one or more breakable members 1025. The breakable members 1025 may be located on an edge of the extending tab 1085 surrounded by the inset wall 1091. For example, as described above, there may be a small gap between the inset wall 1091 and the flange 1083, with the breakable members 1025 located in the gap and connecting the flange 1083 to the inset wall 1091. As shown in FIG. 3, the one or more breakable members 1025 may be located at the top / upper end of the flange 1083 (shown in FIGS. 2, 4A, and 4B), opposite the notched end of the inset wall 1091. The top / upper end of the flange 1083 is opposite the portion / end from which the engagement protrusion 1082 extends. In some embodiments, even if the side edge of the flange 1083 faces the notched edge of the inset wall 1091, the breakable member may not be located in the gap.

[0027] The breakable member 1025 may be configured to break when sufficient pressure is applied to move the flip-top lid 1022 from an initial closed position ( FIG. 3 ) to a subsequent open position ( FIG. 6 ). The breakable member 1025 may have a variety of forms, arrangements, and configurations. As previously described, the flange 1083 of the extending tab 1085 may be connected to the inset wall 1091 via the breakable member 1025 before the breakable member 1025 breaks or separates. Once the breakable member breaks, the extending tab 1085 may separate from the inset wall 1091 as the flip-top lid 1022 is moved from the initial closed position to the open position. In other words, the breakable member 1025 connects the flange 1083 to the inset wall 1091 in the closed configuration before the flip-top lid 1022 is opened for the first time.

[0028] 4A and 4B are cross-sectional views illustrating the closure cap 1018 in its as-manufactured and initially closed configurations.

[0029] In some embodiments, a method of manufacturing the closure cap 1018 may include forming the molded closure cap in an initial open or as-manufactured configuration. As an example, the closure cap 1018 is formed in a molding mold in an initial open configuration and, after molding, is removed from the mold in this configuration (shown in FIG. 4A).

[0030] In one embodiment, the breakable member 1025 is molded with the rest of the closure cap 1018. Additionally, the breakable member 1025 may be weakened beyond its structural design by applying a tool such as a laser, knife, stamping, or the like.

[0031] As an example, the closure cap 1018 is molded as a single unitary structure. More specifically, the closure cap 1018 is typically formed as a single, unitary structure and is constructed of the same material. In some forms, the closure cap 1018 may be molded as a single unitary structure and removed from a mold, or printed as a single unitary structure.

[0032] Additionally, various tools, such as mold slides, lifts, pins, and the like, may be used to create specific shapes during the molding operation to form specific elements of the closure cap 1018. Additionally, post-molding processes may be used in addition to or in place of these specialized molding tools. Examples of post-molding tools include knives, lasers, or punching devices. As an example, the hinge 1019 and the gap between the inset wall 1091 and the flange 1083 may be formed in part by molding tools and in part by post-molding tools.

[0033] A method for manufacturing the closure cap 1018 may include, for example, moving the flip-top lid 1022 from an initial open position ( FIG. 4A ) to an initial closed position ( FIG. 4B ) after removing the molded closure cap from the mold. Prior to shipping to a consumer, the flip-top lid 1022 pivots about the hinge 1019 and moves from the initial open position ( FIG. 4A ) to the initial closed position ( FIG. 4B ), thereby forming the closure cap 1018 in an initial closed configuration. When the flip-top lid 1022 is in the initial closed position, the flip-top lid 1022 is positioned on the base 1020 with the internal protrusion 1090 blocking the opening 1034 in the central portion 1030 of the base 1020. Furthermore, in the initial open configuration (i.e., the configuration after molding and before initial closure), the extending tab 1085 is connected to the flip-top lid 1022 via the breakable member 1025, so that when the flip-top lid 1022 rotates about the hinge 1019 to move from the initial open configuration to the initial closed position, the extending tab 1085 and the breakable member 1025 also move in accordance with the movement of the flip-top lid 1022.

[0034] When the flip-top lid 1022 is in the closed position, the engagement protrusion 1082 of the extending tab 1085 is inserted through a receiving opening 1088 in the recessed surface 1074 of the base 1020. The receiving opening 1088 may be located at a position corresponding to the engagement protrusion 1082 when the flip-top lid 1022 is in the closed position. For example, the receiving opening 1088 may be located on the base 1020 opposite or corresponding to the engagement protrusion 1082. In this manner, as the engagement protrusion 1082 extends and advances toward the base 1020, it is inserted into the base 1020 through the receiving opening 1088.

[0035] In some embodiments, when forming the initial closed configuration from the initial open configuration, as the flip-top lid 1022 approaches the base 1020 and the detent / barb 1082b of the engagement protrusion 1082 contacts the top surface of the base 1020 adjacent the receiving opening 1088, the lid movement may pause or stop unless a force is applied to continue moving it toward the closed position because the width of the receiving opening 1088 is slightly less than the maximum width of the detent / barb 1082b of the engagement protrusion 1082. The force required to fully seat the flip-top lid 1022 in the closed position can be applied in a variety of ways. This force varies depending on the size and flexibility of the detent / barb 1082b and the top wall of the base 1020 adjacent the receiving opening 1088. When sufficient force is applied, the detent / barbed portion 1082b of the engagement projection 1082 snaps through the receiving opening 1088 and into the base 1020, with the detent / barbed portion 1082b positioned below the receiving opening 1088 and the extending tab 1085 fixedly attached to the base 1020. In this configuration, the elongated portion 1082a is disposed within the receiving opening 1088. After initial closure, the engagement projection 1082 engages the receiving opening 1088 in the top wall of the base adjacent the recess 1070.

[0036] As mentioned above, in certain configurations, the width of the flange 1083 of the extending tab 1085 is greater than the width of the receiving opening 1088. In some embodiments, the width of the flange 1083 of the extending tab 1085 is slightly greater than the width of the receiving opening 1088. When the engagement protrusion 1082 engages with the receiving opening 1088, the flange 1083 of the extending tab 1085 can be positioned near and / or above the receiving opening 1088.

[0037] 5 is a partial perspective view showing the engagement protrusion 1082 after an initial closure of the flip-top lid 1022. In the initial closed configuration, i.e., after an initial closure of the flip-top lid 1022 and before a subsequent opening, at least a portion of the engagement protrusion 1082, e.g., the locking tab / barb 1082b, may be located below the top wall of the base 1020.

[0038] More specifically, as an example, the locking claw / barbed portion 1082b of the engaging projection 1082 has a narrow, pointed tip and a pair of sloping surfaces or sides that flare outward toward each other, which allows the engaging projection 1082 to gently deflect the top wall adjacent to the receiving opening 1088, allowing the engaging projection 1082 to pass through the entrance of the receiving opening 1088. The entrance may be at the bottom of the receiving opening 1088. As an example, the shape of the engaging projection 1082 prevents the engaging projection 1082 from being retracted from the receiving opening 1088 or from being easily removed by hand. Furthermore, the tip of the engaging projection 1082 (e.g., the tip of the locking claw) corresponds to or aligns with the receiving opening 1088 when the engaging projection 1082 is pressed into the receiving opening 1088.

[0039] During the process of closing the flip-top lid 1022, the lid shoulder 1052 of the flip-top lid 1022 engages the base shoulder 1054 of the base 1020, causing the lid shoulder 1052 and base shoulder 1054 to resist movement in the closing direction, but with the application of force, they snap over one another, with the lid shoulder 1052 seated in a recess below the base shoulder 1054. In one configuration, this engagement between the lid shoulder 1052 and the base shoulder 1054 holds the flip-top lid 1022 in the closed position. In fact, when the flip-top lid 1022 is in the closed position, the lid shoulder 1052 engages the base shoulder 1054 and remains in the closed position unless an opening force is applied. This engagement between the lid shoulder 1052 and the base shoulder 1054 is useful for preventing the flip-top lid 1022 from accidentally opening due to unintended force, such as during transport or when displayed in a store.

[0040] The lid shoulder 1052 and base shoulder 1054 may be formed from a flexible material. In some embodiments, the entire closure cap 1018 may be formed from a flexible material. This flexible material includes any type of material that can bend when a force is applied. The degree of bending and the force required to bend the material may vary. As described below, various plastic and polymeric materials that have this flexibility may be suitable for the teachings of the present disclosure.

[0041] FIG. 6 is a perspective view illustrating a subsequent opening configuration of the closure cap 1018. After initial closure, a user or consumer can apply a force to the flip-top lid 1022 in a direction substantially away from the base 1020. The action of moving the flip-top lid 1022 away from the base 1020 can cause the flip-top lid 1022 to rotate or pivot about the hinge 1019. Referring back to FIG. 3 , one method for applying the upward force can be by engaging the upper edge or top surface 1072 of the recess 1070. As shown, the top surface 1072 of the recess 1070 is positioned opposite the bottom surface 1074 of the recess 1070. The top surface 1072 of the recess 1070 can be part of the top wall of the flip-top lid 1022, and the bottom surface 1074 of the recess 1070 can be part of the top wall of the base 1020. Alternatively, a user can pull the top surface 1072 upward, away from the base 1020. The flip-top lid 1022 can pivot about a hinge 1019 located substantially opposite the lip-like opening of the recess 1070.

[0042] When the flip-top lid 1022 is in the open configuration, the internal protrusion 1090 of the flip-top lid 1022 moves from a position blocking or obstructing the opening 1034 in the base 1020 to a position away from the opening 1034, thereby leaving the opening 1034 unobstructed and allowing the fluid 5 within the bottle 10 to flow therethrough.

[0043] During use, pressure applied to the flip-top lid 1022 by a user or other object can cause the flip-top lid 1022 to pivot or move about the hinge 1019 from an initial closed position ( FIG. 3 ) to a subsequent open position ( FIG. 6 ). Because the extension tab 1085 is fixedly attached to the base 1020 after initial closure by the engagement of the locking protrusion 1082 of the extension tab 1052 with the receiving opening 1088 of the base 1020, this action separates, severs, or breaks the breakable member 1025 rather than removing the extension tab 1085 from the base 1020. The breakable member 1025 can be broken or separated into at least one of a first part and a second part. Even if the breakable member 1025 breaks or separates into at least one of the first part and the second part, both the first part and the second part remain attached to the closure cap 1018. For example, the first and second parts of the broken breakable member remain attached to at least the inset wall 1091 and / or flange 1083 of the extending tab 1085. For example, if the breakable member 1025 separates into two parts, at least one part is attached to the extending tab 1085 and the other part is attached to the inset wall 1091. In this manner, the small piece of plastic forming the breakable member 1025 is more likely to be recycled along with the remainder of the closure cap 1018. Furthermore, a user can visually and / or tactilely confirm the broken / torn or cut breakable member 1025 and recognize that the closure cap 1018 has previously been opened.

[0044] Furthermore, because the extension tab 1085 is fixedly attached to the base 1020 after initial closure, the extension tab 1085 remains attached to the closure cap 1018 (i.e., the base 1020) whether in the closed configuration shown in Figure 3 or the later open configuration shown in Figure 6. In this manner, the small piece of plastic that forms the extension tab 1085 is also likely to be recycled.

[0045] As shown in FIG. 1B, the closure cap 1018 can be used with a variety of bottles. In one exemplary configuration, a filled container body is sealed to the fluid therein by a liner associated with the closure cap. For example, a liner made of paperboard, plastic, and / or metal material can be attached to the neck of the container body to seal the fluid within the container bottle. In this manner, the container can include multiple tamper-evident features, such as a liner secured to the neck of the container body and a liner secured to the opening of the container body.

[0046] If the bottle neck includes a liner, the closure cap 1018 typically includes a texture or multiple ribs (ribs 1080) on the lower portion of the peripheral skirt, i.e., the lower portion of the sidewall, to facilitate gripping the closure cap 1018 (see FIG. 3). The ribs 1080 on the lower wall of the base 1020 facilitate gripping the closure cap 1018 to disengage the internal threads 1032 of the base (see FIGS. 4A and 4B) from the external threads 16, 16″ of the neck (see FIG. 1B) when removing the entire closure cap 1018 from the container body 12. The ribs 1080 can also be included on the closure cap 1018 even if the bottle does not include a liner. In other configurations, the ribs 1080 can be omitted from the closure cap 1018. For example, the bottle 12″ shown in FIG. 1B is particularly suitable because it includes a structure that securely holds the closure cap on the bottle, even without ribs on the closure cap 1018.

[0047] Additionally, in configurations such as bottle 10 that incorporate non-liner tamper-evident features according to the present disclosure, closure cap 1018 is attached to container body 12 without incorporating a liner.

[0048] Additionally, the disclosures herein may be combined with various bottle features described in U.S. Patent Application No. 17 / 714,041 and International Patent Application No. PCT / US2020 / 039387, filed June 24, 2020, the entire contents of which are incorporated herein by reference.

[0049] In other configurations, the closure cap 1018 can be securely attached to the container body 12 or the container body 12″ shown in FIG. 1B. The present disclosure allows for the use of a bottle without a liner sealingly attached to the neck of the bottle, avoiding the release of small plastic particles when the container is opened. Additionally, by including an exterior tamper-evident element (e.g., a breakable member) on the closure cap 1018, the food package can be sold without a liner while still providing the safety or package integrity function. Also, as described in the above-referenced application, by providing a closure cap retention mechanism such as interrupted threads with spaced threads and a ratchet or other protrusion that engages the spaces and prevents the closure cap from being removed from the bottle, a consumer can visually identify potential tampering with the closure cap 1018 and need not be concerned that the closure cap 1018 may have been unscrewed or otherwise removed prior to purchase.

[0050] More specifically, FIG. 1B shows a container body 12″ having interrupted threads and protrusions 16″ that securely attach the closure cap 1018″ and prevent manual removal. The closure cap 1018″ includes a tamper-evident structure or package integrity feature according to the present disclosure and the threads and ratchet protrusions described in the above-referenced co-pending U.S. patent application Ser. No. 17 / 714,041 and International Patent Application No. PCT / US2020 / 039387, filed June 24, 2020. Furthermore, providing the closure cap 1018″ with such a retention mechanism prevents the closure cap 1018″ from being unscrewed from the container bottle 12″, requiring a user or consumer to open the flip-top lid to access the contents within the container body 12″ after the closure cap 1018″ is attached.

[0051] In some embodiments, the closure cap is constructed from a single material, such as polypropylene, other food-grade plastic or polymer, or similar recyclable material. In operation, the closure cap being constructed from a single material may increase the ease and likelihood of recycling the material. Furthermore, by configuring the package integrity feature or tamper-evident structure according to the present disclosure to be completely inseparable from the rest of the closure cap, more of the plastic closure cap can be recycled.

[0052] In some embodiments, materials may be selected to have a particular surface tension. For example, one or more surfaces of the closure cap 1018 may be roughened or textured to provide flow resistance for the fluid 5 and help control flow during dispensing. Portions of the interior surface of the closure cap 1018 may be textured to inhibit flow or smooth to facilitate the passage of the fluid 5. Smooth surfaces may result in faster and / or less controllable fluid flow, which may reduce surface tension and cause leakage of the product or separated components of the product. The finish of the material and the method of molding the component may also affect the surface tension of the component and facilitate control of fluid flow. For example, portions of the closure cap 1018 may be formed in a manner that creates a rough surface, thereby affecting the flow of the fluid 5.

[0053] The advantages of the containers disclosed herein are further realized when the closure caps and / or bottles can be used in combination with multiple differently configured containers. Indeed, the teachings presented herein (e.g., container bodies and closure caps) can be used in combination with various other closure cap and container body features.

[0054] For example, a tamper-evident mechanism or structure according to the present disclosure may be incorporated into a closure cap having an internal shaft and disk to allow dispensing or metering of contents or fluid 5 within a container body 12. In one exemplary configuration, these teachings may be incorporated into U.S. Patent Application Nos. 17 / 353,376, 17 / 353,326, 17 / 353,484, and 17 / 353,446 (all filed June 21, 2021), International Patent Application No. PCT / US2019 / 067485 (filed December 19, 2019), U.S. Patent Application No. 62 / 783,790 (filed December 19, 2018), and the like. The present invention can be combined with metering elements described in International Patent Application No. PCT / US2020 / 035840 (filed June 3, 2020) and U.S. Patent Application No. 62 / 903,245 (filed September 20, 2019), which claims priority to International Patent Application No. PCT / US2020 / 035840 (filed June 3, 2020) and U.S. Patent Application No. 62 / 903,245 (filed September 20, 2019), all of which are incorporated herein by reference in their entireties.

[0055] Thus, if the closure cap 1018 includes an internal shaft and a metering disc, the outlet 1034 may or may not include a silicone membrane or rubber valve, making the closure cap more easily recyclable if it does not include a silicone membrane.

[0056] 7-9, a closure cap 1118 according to another embodiment is shown. FIG. 7 is a perspective view showing the closure cap 1118 in an initial open position in some embodiments. FIG. 8 is a perspective view showing the closure cap 1118 in an initial closed position in some embodiments. FIG. 9 is a perspective view of the closure cap 1118 in a later open position.

[0057] For the sake of brevity and clarity, the reference numerals of features of the closure cap 1118 in the current embodiment that correspond to features of the closure caps of the previous embodiments have been prefixed with "11" instead of "10" as used in FIGS. 2-6. For example, a closure cap feature designated with the reference numeral "1090" would be designated with the reference numeral "1190" for the closure cap 1118. The closure cap 1118 can be incorporated into any dispensing bottle or container body in a manner similar to that described in the previous embodiment. Furthermore, unless otherwise noted, the closure cap 1118 can be incorporated in combination with any feature of the previous embodiment (e.g., closure cap 1018) and the following embodiments (e.g., closure caps 1218-2818). This also applies to the other embodiments described hereinafter.

[0058] Referring to FIG. 7 , the closure cap 1118 includes a base 1120, a flip-top lid 1122 hingedly connected to the base 1120, an inset wall 1191, an extending tab 1185 extending from the inset wall 1191, and one or more breakable members 1125. The flip-top lid 1122 is movable between an open position ( FIGS. 7 and 9 ) and a closed position ( FIG. 8 ). The flip-top lid 1122 and the base 1120 form a recess 1170 in the outer wall of the closure cap 1118 when the flip-top lid 1122 is in the closed position. This recess 1170 may provide a gripping area where a user may apply force to move the flip-top lid 1122 from the closed position to the open position. The inset wall 1191 is positioned a predetermined distance from the outer wall of the closure cap 1118 and, in some configurations, may extend from the top wall of the flip-top lid 1122. The extending tab 1185 may include a flange 1183 extending from the inset wall 1191 and an engaging protrusion 1182 extending from the flange 1183. The breakable member 1125 is disposed between and connects the inset wall 1191 and the flange 1183 in the initial open position (FIG. 7) and the initial closed position (FIG. 8).

[0059] 7, the engagement projection 1182 may include a pair of hooks, with the ends of each hook extending outward from one another. In use, a gap between the two hooks allows the hooks to flex inward toward one another as the engagement projection 1182 passes through a receiving opening 1188 in the top wall of the base 1120. The flange 1183 of the extension tab 1185 may be smaller than the flange 1083 of the closure cap 1018 of FIG. 2.

[0060] 7, in some embodiments, the base 1120 may include a central portion 1130 and a substantially flat portion 1162. The substantially flat portion 1162 and the recessed surface of the base 1120 may extend around the periphery of the central portion 1130. In some embodiments, the sidewall of the central portion 1130 facing the recess 1170 may include a step 1136 near the top surface of the central portion 1130.

[0061] In some embodiments, the inset wall 1191 includes a step 1196 extending from the inset wall 1191 (see FIG. 7). The step 1196 may be located on an inner surface of the inset wall 1191 facing the recess and / or opposite the side wall of the flip-top lid. In some embodiments, the inset wall 1191 may have a notch 1191′ (see FIG. 9) in the center of the edge, and the step 1196 may be located adjacent to the notch 1191′ of the inset wall 1191.

[0062] When the flip-top lid 1122 is moved to the closed position, the shoulder 1196 of the inset wall 1191 may snap in under the shoulder 1136 such that the shoulder 1196 engages the shoulder 1136. The engagement between the shoulder 1196 and the shoulder 1136 holds the flip-top lid 1122 in the closed position and prevents the flip-top lid 1122 from being moved to the open position unless sufficient force is applied. In this manner, the engagement between the shoulder 1196 and the shoulder 1136 is useful for preventing the flip-top lid 1122 from being inadvertently moved to the open position in certain situations, such as during transportation or when displayed on a store shelf.

[0063] In some embodiments, the flange 1183 of the extending tab 1185 is positioned adjacent to the edge of the inset wall 1191, and the breakable member 1125 connects the flange 1183 of the extending tab 1185 to the inset wall 1191. This ensures that the breakable member 1125 connects the extending tab 1185 to the inset wall 1191 when the flip-top lid 1122 is in the initial open position and the initial closed position.

[0064] Similar to the previous embodiment, when the flip-top lid 1122 is moved from the initial open position to the closed position, the locking protrusion 1182 is inserted into the base 1120 through the receiving opening 1188. This mechanism securely attaches the extending tab 1185 to the base 1120. When the flip-top lid 1122 is initially closed, the flange 1183 of the extending tab 1185 rests on the recessed surface of the base 1120 adjacent the receiving opening 1188.

[0065] As previously mentioned, the breakable member 1125 is broken during or at the time the flip-top lid 1122 is moved from the initial closed position ( FIG. 8 ) to the subsequent open position ( FIG. 9 ). As shown in FIG. 9 , after the flip-top lid 1122 is moved from the initial closed position to the subsequent open position ( FIG. 9 ), the extension tab 1185 may remain secured to the closure cap 1118, i.e., the base 1120, via the engagement of the locking protrusion 1182 with the receiving opening 1188. The broken breakable member 1125 may also remain secured to the closure cap 1118, as shown in FIG. 9 . This breaking of the breakable member 1125 indicates that the flip-top lid 1122 has been opened once.

[0066] In one embodiment, the space and material required to manufacture the closure cap can be reduced by locating both the extending tab 1185 (which functions as an anti-tamper indicator) and the shoulder 1196 configured to hold the flip-top lid 1122 in the closed position on the inset wall 1191. This configuration allows for a smaller profile for the closure cap. Additionally, locating both the extending tab 1185 and the shoulder 1196 on the inset wall 1191 simplifies the manufacturing process by allowing both components to be manufactured simultaneously.

[0067] 10-12 illustrate another closure cap 1218 according to some embodiments. FIG. 10 is a perspective view illustrating an initial open configuration of the closure cap 1218 according to some embodiments. FIG. 11 is a perspective view illustrating an initial closed configuration of the closure cap 1218 according to some embodiments. FIG. 12 is a perspective view illustrating a subsequent open configuration of the closure cap 1218 according to some embodiments. The embodiment illustrated in FIGS. 10-12 may be a variation of the closure cap 1118 illustrated in FIGS. 7-9. The closure cap 1218 illustrated in FIGS. 10-12 may have a similar structure to the closure cap 1118 illustrated in FIGS. 7-9. The closure cap 1218 illustrated in FIGS. 10-12 may differ from the closure cap 1118 illustrated in FIGS. 7-9 in the shape, structure, position, and / or configuration of the extending tab 1285 and receiving openings 1288a, 1288b.

[0068] 10 , in some embodiments, the extending tab 1285 includes a flange 1283 and a locking protrusion 1282. Like the locking protrusion 1182 in FIGS. 7-9 , the locking protrusion 1282 in FIGS. 10-12 also includes a pair of hooks, but the spacing between the hooks of the locking protrusion 1282 may be wider than the spacing between the hooks of the locking protrusion 1182 in FIG. 7. Each of the pair of hooks may extend from opposite ends of the flange 1283.

[0069] In contrast to the configuration in which the pair of hooks of the locking projection 1182 are inserted into a single receiving opening 1188 of the base 1120 (see FIGS. 7-9), each of the pair of hooks of the locking projection 1282 is generally configured to be inserted into a separate receiving opening 1288a, 1288b. In some embodiments, the base 1220 includes two receiving openings 1288a, 1288b. In one aspect, the two receiving openings 1288a, 1288b may be disposed on the recessed surface of the base and each may be aligned with a respective one of the pair of hooks of the locking projection 1282. The width of each of the two receiving openings 1288a, 1288b is narrower than the width of the flange 1283 of the extension tab 1285.

[0070] As shown in FIG. 11, when the flip-top lid 1222 moves from the initial open position to the initial closed position, each hook of the locking protrusion 1282 is inserted into the receiving openings 1288a and 1288b, respectively, and the flange 1283 of the extending tab 1285 is positioned above the two receiving openings 1288a and 1288b.

[0071] In use, when a user pivots or hinges the flip-top lid 1222 from an initial closed position (FIG. 11) to a subsequent open position (FIG. 12), the breakable member 1225 breaks instead of the extending tab 1285 disengaging from the base 1220. As shown in FIGS. 12 and 12A, after subsequent opening, the extending tab 1285 and at least a portion of the broken breakable member 1225 may remain secured to the base.

[0072] Figures 13-17 illustrate another closure cap 1318 according to some embodiments. Figure 13 is a perspective view showing the closure cap 1318 in an initial open configuration. Figure 14 is a perspective view showing the initial closed configuration.

[0073] In some embodiments, the closure cap 1318 comprises a base 1320, a flip-top lid 1322 hingedly connected to the base 1320, an inset wall 1391, an extending tab 1385 extending from the inset wall 1391, and one or more breakable members 1325. The flip-top lid 1322 is movable between an open position ( FIGS. 13 and 17 ) and a closed position ( FIG. 14 ). The flip-top lid 1322 and the base 1320 form a recess 1370 in the outer wall of the closure cap 1318 when the flip-top lid 1322 is in the closed position. The inset wall 1391 is positioned a predetermined distance from the outer wall of the closure cap 1318 and typically extends from the top wall of the flip-top lid 1322. The extending tab 1385 includes a flange 1383 extending from the inset wall 1391 and a locking protrusion 1382 extending from the flange 1383. The breakable member 1325 is disposed between the inset wall 1391 and the flange 1383 and connects the inset wall 1391 and the flange 1383 when the flip-top lid 1322 is in the initial open position ( FIG. 13 ) and the initial closed position ( FIG. 14 ).

[0074] In some embodiments, the base 1320 may have a recess 1387 on its recess-forming surface. The base 1320 may further have a receiving opening 1388 on a bottom surface of the recess 1387. The recess 1387 of the base 1320 may be formed to surround the receiving opening 1388 of the base 1320. In some embodiments, the recess 1387 may be positioned a predetermined distance from the opening of the recess 1370. In some embodiments, the width and length of the recess 1387 are slightly larger than the width and length of the flange 1383 of the extending tab 1385. The width and / or length of the receiving opening 1388 are smaller than the width and / or length of the flange 1383.

[0075] In some embodiments, the inset wall 1391 may extend to contact or nearly contact the underside 1374 of the recess 1370 when the flip-top lid 1322 is in the closed position. In other words, when the flip-top lid 1322 is in the closed position, the edge of the inset wall 1391 may contact the underside 1374 of the recess 1370, or there may be a slight gap between the edge of the inset wall 1391 and the underside 1374 of the recess 1370.

[0076] In some embodiments, the inset wall 1391 does not have a notch at its lower edge, and the lower edge of the inset wall 1391 may have a smooth curvature that generally corresponds to the recessed surface of the base. The flange 1383 of the extension tab 1385 may extend from the lower edge of the inset wall 1391 and be generally parallel to the inset wall 1391. Thus, the flange 1383 may protrude from the lower edge of the inset wall 1391.

[0077] In some embodiments, the locking protrusion 1382 may extend in the same direction as the flange 1383 extends from the inset wall 1391. In one embodiment, the locking protrusion 1382 may be an elongated protrusion having a generally arrowhead-shaped cross-section. For example, the locking protrusion 1382 may have an elongated portion and a locking tab formed on one end thereof.

[0078] In some embodiments, the breakable member 1325 may be disposed between the inset wall 1391 and the flange 1383 of the extending tab 1385 prior to the initial opening of the flip-top lid 1322 (i.e., in the initial open and initial closed configurations). The breakable member 1325 may be configured to break or separate into component parts when the flip-top lid 1322 is moved from the initial closed position to the open position.

[0079] 15A and 15B are cross-sectional views illustrating an as-manufactured configuration and an initial closed configuration of the closure cap 1318. A method of manufacturing the closure cap 1318 may include forming a molded closure cap as shown in FIGS. 13 and 15A in a molding die, and then removing the molded closure cap from the molding die in the initial open configuration. The removed molded closure cap 1318 is in the initial open configuration.

[0080] The manufacturing method may include moving the flip-top lid 1322 from an initial open position to a closed position after removing the closure cap 1318 from the molding die. The flip-top lid 1322 pivots about the hinge 1319 to move from the initial open position ( FIG. 15A ) to the closed position ( FIG. 15B ), placing the closure cap 1318 in an initial closed configuration. As the flip-top lid 1322 moves from the initial open position to the closed position, the inset wall 1391, the flange 1383 and the extending tab 1385 including the locking protrusion, and the breakable member 1325 move with the flip-top lid 1322. When the flip-top lid 1322 is moved to the initial closed position, the locking tab of the locking projection 1382 passes through the receiving opening 1388 and snaps into or below the recessed surface of the base 1320, and the flange 1383 of the extending tab 1385 may be positioned adjacent to, within or above the recess 1387.

[0081] 16 is a partial perspective view from the inside of the base 1320 showing the locking protrusion 1382 in an initial closed configuration of the flip-top lid 1322, according to some embodiments of the present invention. As shown in FIG. 16, the locking protrusion's locking tab engages the receiving opening 1388 by locking into the underside of a recess 1387 adjacent the receiving opening.

[0082] FIG. 17 is a perspective view of the closure cap 1318 in a subsequent open configuration, according to some embodiments of the present invention. FIG. 17A is an enlarged view of circle 17A of FIG. 17. In this embodiment, the flip-top lid 1322 is movable from a closed position to an open position after initial closure. In use, force applied to the flip-top lid 1322 by a user or other object causes the flip-top lid 1322 to pivot or hinge from the initial closed position ( FIG. 14 ) to the subsequent open position ( FIG. 17 ). Because the extension tab 1385 is fixedly attached to the base 1320 by engagement of its locking protrusion 1382 with the receiving opening 1388 in the base 1320, this movement may separate, cut, or otherwise damage or destroy the cutting member 1325 rather than disengage the extension tab 1385 from the base 1320. As discussed above, pieces of the broken cutting member 1325 remain attached to at least the inset wall 1391 and / or the flange 1383 of the extending tab 1385 .

[0083] 17A , even after the flip-top lid is initially opened, the flange 1383 of the extending tab 1385 can be disposed within the recess 1387. In some embodiments, the width, length, and depth of the recess 1387 are greater than the width, length, and depth of the flange 1383, such that the entire flange 1383 can be received within the recess 1387. By receiving the entire flange 1383 within the recess 1387, the flange 1383 is positioned below the adjacent recess-forming surface (i.e., the lower surface 1374 of the recess 1370) and does not interfere with a user's access to and use of the recess 1370 when opening the flip-top lid 1322. In some embodiments, at least a portion or all of the cutting member 1325 can be disposed within the recess 1387.

[0084] 18-20 illustrate another closure cap 1418 according to some embodiments of the present invention. Figure 18 is a perspective view of the closure cap 1418 in an initial open configuration, Figure 19 is a perspective view of the closure cap 1418 in an initial closed configuration, and Figure 20 is a perspective view of the closure cap 1418 in a subsequent open configuration.

[0085] 18, the closure cap 1418 includes a base 1420, a flip-top lid 1422 hingedly connected to the base 1420, an inset wall 1491, an extending tab 1485 extending from the inset wall 1491, and one or more breakable members 1425. The flip-top lid 1422 is movable between an open position (FIGS. 18 and 20) and a closed position (FIG. 19). The flip-top lid 1422 and the base 1420 form a recess 1470 in the outer wall of the closure cap 1418 when the flip-top lid 1422 is in the closed position. The inset wall 1491 is spaced a distance from the outer wall of the closure cap 1418 and extends from the top wall of the flip-top lid 1422. The extending tab 1485 can include a flange 1483 extending from the inset wall 1491 and a locking protrusion 1482 extending from the flange 1483. The breakable member 1425 is disposed between the inset wall 1491 and the flange 1483 and connects the inset wall 1491 and the flange 1483 when the flip-top lid 1422 is in the initial open position ( FIG. 18 ) and the initial closed position ( FIG. 19 ).

[0086] In some embodiments, the base 1420 can include a recess 1487 configured to receive the flange 1483 of the extending tab 1485 and a receiving opening in the bottom surface of the recess 1487 .

[0087] In some embodiments, the base 1420 can include a central portion 1430 and a substantially flat portion 1462. The substantially flat portion 1462 and the recessed surface of the base 1420 extend around the periphery of the central portion 1430. In some embodiments, the depression 1487 can be disposed in the recessed surface of the base 1420 and contact a sidewall of the central portion 1430.

[0088] In some embodiments, the sidewall of the central portion 1430 facing the recess 1470 may include a step 1436 near the top surface of the central portion 1430. In some embodiments, the step 1436 is discontinuous, such that the sidewall of the central portion 1430 facing the recess 1470 may further include a central flat, opening, or non-stepped portion 1437 near the top surface of the central portion 1430. In this embodiment, the flat portion 1437 may be disposed between two portions of the step 1436 separated by the flat portion 1437. The extending tab 1485 may be configured to pass through the flat portion 1437 when the flip-top lid 1422 moves from the open position to the closed position. The flat portion 1437 may prevent damage to the extending tab 1485 and / or the breakable member 1425 when the flip-top lid 1422 is moved from the open position to the closed position. In some embodiments, the flat portion 1437 can be positioned in alignment with the recess 1487 of the base 1420 .

[0089] When the flip-top lid 1422 is moved to the closed position, the shoulder 1496 of the inset wall 1491 is configured to snap into or slip under the shoulder 1436, whereupon the shoulder 1496 of the inset wall 1491 may engage the shoulder 1436. The engagement of the shoulder 1496 with the shoulder 1436 may help or facilitate the flip-top lid 1422 remaining in the closed position until sufficient force is applied. The engagement of the shoulder 1496 with the shoulder 1436 may also prevent the flip-top lid 1422 from accidentally moving during transport, in-store display, etc.

[0090] Similar to the previous embodiment, when the flip-top lid 1422 is moved from the initial open position to the closed position, the locking protrusion 1482 is inserted through the receiving opening into the base 1420. By this mechanism, the extending tab 1485 is fixedly attached to the base 1420. After the flip-top lid 1422 is initially closed, the flange 1483 of the extending tab 1485 is positioned within the recess 1487 of the base 1420, as shown in FIGS.

[0091] As described above, the breakable member 1425 is cut or broken when the flip-top lid 1422 moves from the initial closed position ( FIG. 19 ) to the subsequent open position ( FIG. 20 ). As shown in FIGS. 20 and 20A (an enlarged view of the circled portion in FIG. 20 ), the extending tab 1485 remains secured to the base 1420 even after the flip-top lid 1422 moves from the initial closed position to the subsequent open position ( FIG. 20 ). The broken breakable member 1425 also remains secured to the closure cap 1418, as shown in FIG. 20 . The broken breakable member 1425 can indicate that the flip-top lid 1422 has been opened.

[0092] In some embodiments, even when the flange 1483 of the extending tab 1485 is positioned in the recess 1487, at least a portion of the breakable member 1425 may be positioned above the recess 1487 to increase the visibility of the breakable member 1425 and to make it easier to determine whether the breakable member 1425 is broken.

[0093] By incorporating a flat or non-stepped portion 1437, the recess 1487 can be configured to contact the sidewall of the central portion 1430, allowing the extending tab 1485 and breakable member 1425 to be positioned near or at the innermost portion of the recess 1470. Locating the extending tab 1485 at the innermost portion of the recess 1470 advantageously minimizes interference with the recess 1470 by a user, enhancing accessibility. This allows for easier manual access when a user attempts to use the recess 1470 to open the flip-top lid 1422. Furthermore, this configuration reduces the likelihood of a user being injured by a broken breakable member 1425, even if a majority of the breakable member 1425 is located above the recess 1487.

[0094] As discussed above, locating the extending tab 1485, which functions as an anti-tamper indicator, and the shoulder 1496, which holds the flip-top lid 1422 in a closed position, on the inset wall 1491 may reduce the space and material required to manufacture the closure cap 1418. Additionally, locating the extending tab 1485 and the shoulder 1496 on the inset wall 1491 simplifies the manufacturing process by allowing both elements to be formed simultaneously or in the same process.

[0095] 21-23 illustrate another closure cap 1518 according to some embodiments of the present invention. Fig. 21 is a perspective view illustrating an initial open configuration of the closure cap 1518, Fig. 22 is a perspective view illustrating an initial closed configuration of the closure cap 1518, and Fig. 23 is a perspective view illustrating a subsequent open configuration of the closure cap 1518. Fig. 23A is an enlarged view of the circled portion of Fig. 23.

[0096] The closure cap 1518 shown in FIGS. 21-23 may be a variation of the closure cap 1418 shown in FIGS. 18-20. In some embodiments, the extending tab 1585 may be positioned so that the closure cap 1518 is asymmetrical. Assuming that the center of the opening of the recess 1570 is the front center of the closure cap 1518, the extending tab 1585 and the indentation 1587 may be positioned on one side of the closure cap 1518. The flat or non-stepped portion 1537 may also be positioned on one side of the closure cap 1518, aligned with the indentation 1587. For example, the indentation 1587 may be positioned on one side of the recess 1570, and the extending tab 1585 may extend from a corresponding side of the edge of the inset wall 1591. As shown in FIGS. 21-23, the indentation 1587 is positioned to the left of the opening of the recess 1570, and the extending tab 1585 extends from the left side of the corresponding inset wall 1591. In other embodiments, the recess 1587, extending tab 1585, and flat, open, or non-stepped portion 1537 of the base may be located on the right side of the closure cap 1518.

[0097] Figures 24-26 illustrate yet another closure cap 1618 according to some embodiments of the present invention. Figure 24 is a perspective view illustrating the closure cap 1618 in an initial open configuration, Figure 25 is a perspective view illustrating the closure cap 1618 in an initial closed configuration, and Figure 26 is a perspective view illustrating the closure cap 1618 in a subsequent open configuration. Figure 26A is an enlarged view of the circled portion of Figure 26.

[0098] The closure cap 1618 shown in FIGS. 24-26 may be another variation of the closure cap 1418 shown in FIGS. 18-20. In some embodiments, the closure cap 1618 includes a pair of extending tabs, i.e., first extending tab 1685a and second extending tab 1685b. The closure cap 1618 may also include a pair of corresponding recesses, i.e., first recess 1687a and second recess 1687b. Similarly, the closure cap 1618 may include a pair of flats or openings, i.e., first flats or opening 1637a and second flats or opening 1637b.

[0099] In some embodiments, assuming the center of the opening of the recess 1670 is the front center of the closure cap 1618, the first extending tab 1685a, the first recess 1687a, and the first flat or opening 1637a are disposed on one side (e.g., a first side) of the closure cap 1618, and the second extending tab 1685b, the second recess 1687b, and the second flat or opening 1637b are disposed on the other side (e.g., a second side) of the closure cap 1618. In this manner, the extending tabs 1685a, 1685b are disposed generally symmetrically with respect to the closure cap 1618.

[0100] In some embodiments, the pair of extending tabs 1685a, 1685b, the pair of recesses 1687a, 1687b, and the pair of flats or openings 1637a, 1637b may be arranged symmetrically. For example, the first extending tab 1685a, the first recess 1687a, and the first flats or opening 1637a may be arranged on the left side of the closure cap, and the second extending tab 1685b, the second recess 1687b, and the second flats or opening 1637b may be arranged on the right side of the closure cap 1618, such that the left and right sides of the closure cap 1618 are symmetrical.

[0101] Figure 27 shows an initial open configuration of the closure cap 1718, according to some embodiments. Figure 28 is a perspective view showing the closure cap 1718 in a closed configuration prior to initial opening.

[0102] Similar to the previous embodiment, the closure cap 1718 includes a base 1720 and a flip-top lid 1722 coupled to the base 1720 via a hinge connection 1719. The flip-top lid 1722 is movable between an open position ( FIG. 27 ) and a closed position ( FIG. 28 ). The flip-top lid 1722 and the base 1720 form a recess 1770 in an outer wall of the closure cap 1718 when the flip-top lid 1722 is in the closed position. The outer wall of the closure cap 1718 may include a sidewall 1797 of the base 1720 and a sidewall 1799 of the flip-top lid 1722.

[0103] 27-28, the closure cap 1718 includes a first tab 1752 on a sidewall 1799 of the flip-top lid 1722 and a second tab 1753 on a sidewall 1797 of the base 1720. In some embodiments, the first tab 1752 and the second tab 1753 are disposed on one side of the recess 1770. When the flip-top lid 1722 is in the closed position, the first tab 1752 and the second tab 1753 can be aligned with one another.

[0104] 28, a first weld joint 1754 may be disposed (formed) between the first tab 1752 and the second tab 1753. The first weld joint 1754 may rigidly connect the first tab 1752 and the second tab 1753, thereby rigidly connecting the flip-top lid 1722 and the base 1720 after initial closure and prior to opening.

[0105] The first welded joint 1754 is configured to break when the flip-top lid 1722 is moved from an initial closed position to an open position, thereby breaking the connection between the first tab 1752 and the second tab 1753.

[0106] The closure cap 1718 may further include a third tab 1752′ and a fourth tab 1753′ on the other side of the recess. The third tab 1752′ is disposed on the side wall 1799 of the flip-top lid 1722, and the fourth tab 1753′ is disposed on the side wall 1797 of the base 1720. When the flip-top lid 1722 is in the closed position, the third tab 1752′ and the fourth tab 1753′ can be aligned with each other.

[0107] When the flip-top lid 1722 is in the initial closed position, as shown in FIG. 28, a second weld joint 1754′ (shown in FIG. 29C) may be disposed between the third tab 1752′ and the fourth tab 1753′. The second weld joint 1754′ may rigidly connect the third tab 1752′ and the fourth tab 1753′, thereby rigidly connecting the flip-top lid 1722 and the base 1720.

[0108] Like the first welded joint 1754, the second welded joint 1754' is configured to break when the flip-top lid 1722 is moved from an initial closed position to an open position, thereby breaking the connection between the third tab 1752' and the fourth tab 1753'.

[0109] When the closure cap 1718 includes the first weld joint 1754 and the second weld joint 1754', they can rigidly connect the flip-top lid 1722 and the base 1720 when the flip-top lid 1722 is in the initial closed position and can be broken when the flip-top lid is moved from the initial closed position to the open position. In some embodiments, the first weld joint 1754 and / or the second weld joint 1754' can be spot welds.

[0110] In some embodiments, the sidewall of the closure cap 1718 may further include a first recess 1755 in which the first weld joint 1754 is disposed. The first recess 1755 may be located on one side of the recess 1770 (e.g., on or near one side of the open end of the mouth shape of the recess 1770). A first portion 1756 of the first recess 1755 is disposed on the sidewall 1799 of the flip-top lid 1722, and a second portion 1757 of the first recess 1755 is disposed on the sidewall 1797 of the base 1720. The first portion 1756 and the second portion 1757 of the first recess 1755 may each form approximately one half of the first recess 1755. The first tab 1752 is positioned over a first portion 1756 of the first recess 1755 , and the second tab 1753 is positioned over a second portion 1757 of the first recess 1755 .

[0111] In some embodiments, the sidewall of the closure cap 1718 may further include a second recess 1755' for disposing the second weld joint 1754'. The second recess 1755' may be disposed on a second side of the recess 1770 (e.g., at or near the other side end of the mouth-like opening of the recess 1770). A first portion 1756' of the second recess 1755' may be disposed on the sidewall 1799 of the flip-top lid 1722, and a second portion 1757' may be disposed on the sidewall 1797 of the base 1720. The first portion 1756' and the second portion 1757' of the second recess 1755' may each form approximately half of the second recess 1755'. The third tab 1752' may be disposed on a first portion 1756' of the second recess 1755', and the fourth tab 1753' may be disposed on a second portion 1757' of the second recess 1755'.

[0112] In some embodiments, a narrow portion may be provided between the first tab 1752 and the second tab 1753. The narrow portions of the first tab 1752 and the second tab 1753 may form a first weld joint 1754. In some embodiments, the first weld joint 1754 may have a width that is narrower than the adjacent portions of the first tab 1752 and the second tab 1753 and / or the maximum width of the first tab 1752 and the second tab 1753. This narrow portion may reduce the force required to break the first weld joint 1754. Similarly, a narrow portion may be provided between the third tab 1752′ and the fourth tab 1753′, and the second weld joint 1754′ may have a width that is narrower than the adjacent portions of the third tab 1752′ and the fourth tab 1753′ and / or the maximum width of the third tab 1752′ and the fourth tab 1753′. In some configurations, the narrowed portion between the tabs is also where the connection breaks or separates when the closure cap is opened. Further, in some configurations, the weakened or broken portion is configured to visually indicate that the closure cap has been opened. In this manner, the broken, separated, or damaged area may produce an uneven, rough, or visually distinct line, surface, or area that indicates to the user that the closure cap has been opened.

[0113] 29A-29C are side views illustrating the as-manufactured, closed, and initial closed configurations of the closure cap 1718. While Figures 29A-29C only show the second side of the recess 1770, the third and fourth tabs 1752', 1753', the second weld joint 1754', and the second recess 1755', the first and second tabs 1752, 1753, the first weld joint 1754, and the first recess 1755 may be formed in a similar manner.

[0114] 29A, a method of manufacturing a closure cap 1718 may include forming a molded closure cap. The closure cap is molded in an initial open configuration and then removed from the mold. The removed molded closure cap 1718 may be in the initial open configuration as shown in FIGS. 27 and 29A. The removed molded closure cap 1718 may include both first and second tabs 1752, 1753 and third and fourth tabs 1752′, 1753′. Additionally, the removed molded closure cap 1718 may include both a first recess 1755 and a second recess 1755′.

[0115] 29A and 29B, a method of manufacturing a closure cap 1718 may include moving a flip-top lid 1722 from an initial open position (FIG. 29A) to a closed position (FIG. 29B). In FIG. 29B, the flip-top lid 1722 has been moved to the closed position, with the first and second tabs 1752, 1753 and the third and fourth tabs 1752′, 1753′, respectively, aligned and in contact, but the first and second welded joints 1754, 1754′ have not yet been formed.

[0116] FIG. 29C illustrates the closure cap 1718 in an initial closed configuration after forming the first and second weld joints 1754, 1754′. To form the first and second weld joints 1754, 1754′, the first and second tabs 1752, 1753 and the third and fourth tabs 1752′, 1753′ may be welded together. In some embodiments, the welding process is performed by applying heat to the interfaces of the first and second tabs 1752, 1753 and the interfaces of the third and fourth tabs 1752′, 1753′ to melt them together. The heating process can melt the first and second tabs 1752, 1753 into a single piece, as well as the third and fourth tabs 1752′, 1753′ into a single piece. For example, a heated tool, such as a hot stamp, can be applied to the first and second tabs (or portions thereof). By way of example, a heated tool may be applied to the interface of the first and second tabs 1752, 1753 and / or the third and fourth tabs 1752′, 1753′ to form first and second weld joints 1754, 1754′. After the heat is removed, the fused and joined interfaces harden, forming first and second weld joints 1754, 1754′ and securely connecting the flip-top lid 1722 and the base 1720.

[0117] In some embodiments, an ultrasonic welding process may be used to form the first and second weld joints 1754, 1754'. In the ultrasonic welding process, ultrasonic waves are applied to the first and second tabs 1752, 1753 and / or the third and fourth tabs 1752', 1753' to form the first and second weld joints 1754, 1754'. Ultrasonic welding indirectly generates heat in the welded area by converting an electrical signal into ultrasonic waves.

[0118] The first and second tabs 1752, 1753 and the third and fourth tabs 1752', 1753', and the first and second weld joints 1754, 1754' that include them, may be made of any material that can melt at high temperatures and harden at room or low temperatures. In some embodiments, the first and second tabs 1752, 1753 and the third and fourth tabs 1752', 1753', and the first and second weld joints 1754, 1754' that include them may be formed from the same material as other elements / portions of the closure cap 1718.

[0119] As previously discussed, the first and second weld joints 1754, 1754' typically break when or as the flip-top lid 1722 is moved from the initial closed position (after welding) to the subsequent open position. After the flip-top lid 1722 is moved from the initial closed position to the subsequent open position and the first and second weld joints 1754, 1754' break, the first and second tabs 1752, 1753 and the third and fourth tabs 1752', 1753' may remain secured to the closure cap 1718. The broken weld joints 1754, 1754' may also remain secured to the closure cap and may indicate that the flip-top lid 1722 of the closure cap 1718 has been opened.

[0120] 30-34 illustrate another embodiment of a closure cap 1818 according to some embodiments. Figure 30 is a perspective view illustrating an initial open configuration of the closure cap 1818 according to some embodiments. Figure 31 is a perspective view illustrating an initial closed configuration of the closure cap 1818.

[0121] In one embodiment, the closure cap 1818 includes a base 1820, a flip-top lid 1822 hingedly connected to the base 1820, one or more extending tabs 1885, 1885', and one or more breakable members 1825, 1825'. The flip-top lid 1822 is movable between an open position (FIGS. 30 and 34) and a closed position (FIG. 31). The flip-top lid 1822 and the base 1820 form a recess 1870 in the outer wall of the closure cap 1818 when the flip-top lid 1822 is in the closed position.

[0122] The extending tabs 1885, 1885' may include a first extending tab 1885 and a second extending tab 1885'. The first extending tab 1885 may be positioned near a first side edge of the mouth-shaped opening of the recess 1870, and the second extending tab 1885' may be positioned near a second side edge of the mouth-shaped opening of the recess 1870.

[0123] The first and second extending tabs 1885, 1885' may be coupled to the flip-top lid 1822 via breakable members 1825, 1825' in the initial open and initial closed configurations. The first extending tab 1885 may be coupled to the flip-top lid 1822 via the first breakable member 1825, and the second extending tab 1885' may be coupled to the flip-top lid 1822 via the second breakable member 1825'. The first and second extending tabs 1885, 1885' may be coupled at ends of a sidewall 1899 of the flip-top lid 1822.

[0124] In one embodiment, the first extending tab 1885 may include a first flange 1883 and a first locking protrusion 1882 extending therefrom. The first flange 1883 extends from the flip-top lid 1822 prior to initial opening. Similarly, the second extending tab 1885' may include a second flange 1883' and a second locking protrusion 1882' extending therefrom. The second flange 1883' extends from the flip-top lid 1822 prior to initial opening.

[0125] In one embodiment, one or more notches 1823, 1823′ may be formed in the edge of the sidewall 1899 of the flip-top lid 1822. For example, the flip-top lid 1822 may have a first notch 1823 and a second notch 1823′ configured to receive / position the first flange 1883 and the second flange 1883′, respectively (see FIG. 34).

[0126] In some embodiments, first and second reinforcing tabs 1895, 1895′ may be further provided below the first and second cutouts 1823, 1823′ on the inner surface of the sidewall 1899 of the flip-top lid 1822. In this case, at least a portion of the first and second flanges 1883, 1883′ (e.g., portions 1884, 1884′ of the first and second flanges 1883, 1883′ corresponding to the cutouts 1823, 1823′) may have a width substantially the same as the overall width of the sidewall 1899, including the reinforcing tabs 1895 or 1895′. In some embodiments, the first and second locking projections 1882, 1882′ extend from portions 1884, 1884′ of the first and second flanges 1883, 1883′, respectively, that correspond to the reinforcing tabs 1895, 1895′ of the flip-top lid 1822 and may be slightly recessed inward from the sidewall 1899 of the flip-top lid 1822. In one embodiment, the height of the portions 1884, 1884′ of the first and second flanges 1883, 1883′ that correspond to the reinforcing tabs 1895, 1895′ may be slightly greater than the height of the remaining portions 1881, 1881′ (see FIG. 30 ). In one embodiment, portions 1884, 1884' of the first and second flanges 1883, 1883' corresponding to the reinforcing tabs 1895, 1895' may protrude from the non-notched end of the flip-top lid 1822, and the remaining portions 1881, 1881' of the first and second flanges 1883, 1883' may align with the non-notched end of the side wall 1899 of the flip-top lid 1822.

[0127] In one embodiment, the first and second locking projections 1882, 1882' may extend from respective ends of the first and second flanges 1883, 1883' substantially parallel to the flanges 1883, 1883'.

[0128] In some embodiments, the base 1820 may include a central portion 1830 through which the opening 1834 extends and a substantially flat portion 1862. The substantially flat portion 1862 and the underside of the recess 1870 (i.e., the recess-forming surface of the base 1820) may extend around the periphery of the central portion 1830. The peripheral side of the base 1820 includes a peripheral step 1864, which causes the base 1820 to have a concave side that is recessed inwardly from the side wall of the closure cap 1818. The concave side 1853 may extend around or near the substantially flat portion 1862.

[0129] In some embodiments, the flanges 1883, 1883' of the first and second extending tabs 1885, 1885' may be disposed on or near the top surface of the peripheral step 1864 after initial closure of the flip-top lid 1822. Recesses 1886, 1886' may be formed in the recessed side 1853 to receive portions of the first and second flanges 1883, 1883' that correspond to the reinforcing tabs 1895, 1895' that are recessed from the side wall 1899 of the flip-top lid 1822.

[0130] In some embodiments, recesses 1887, 1887' may also be formed in the upper surface of the peripheral step 1864 to compensate for the greater height of the portions 1884, 1884' of the first and second flanges 1883, 1883' corresponding to the reinforcing tabs 1895, 1895'.

[0131] The base 1820 may have a first receiving opening 1888 and a second receiving opening 1888' at or near the top surface of the peripheral step 1864. The first and second engagement projections 1882, 1882' are configured to normally engage the base 1820 by being inserted into the base 1820 through the first and second receiving openings 1888, 1888', respectively. The first and second receiving openings 1888, 1888' may be disposed in recesses 1887, 1887' in the top surface of the peripheral step 1864.

[0132] As an example, the first and second engagement protrusions 1882, 1882′ are configured to be easily pushed into, but not pulled out or removed from, the receiving openings 1888, 1888′ of the base 1820. For example, as shown in FIG. 30 , each of the first and second engagement protrusions 1882, 1882′ may include an extension and an arrowhead-shaped locking tab at the end of the extension.

[0133] In some embodiments, the first breakable member 1825 may be positioned on or near the edge of the flip-top lid 1822 and / or the first flange 1883 surrounded by the first reinforcing tab 1895. The second breakable member 1825' may be positioned on or near the edge of the flip-top lid 1822 and / or the second flange 1883' surrounded by the second reinforcing tab 1895'. As described above, the first and second breakable members 1825, 1825' may connect the first and second extending tabs 1885, 1885', respectively, to the flip-top lid 1822 when the flip-top lid 1822 is in the initial open and initial closed positions. The first and second breakable members 1825, 1825' are configured to break when the flip-top lid 1822 is moved from an initial closed position to an open position, such that the first and second extending tabs 1885, 1885' and the flip-top lid 1822 may be separated when the flip-top lid 1822 is moved from an initial closed position to an open position.

[0134] 32A and 32B are side views illustrating an as-manufactured configuration of a closure cap 1818, a closed configuration from an initial open configuration, and an initial closed configuration. A method of manufacturing the closure cap 1818 may include forming a molded closure cap and then removing the molded closure cap in the initial open configuration from a molding die. The removed molded closure cap 1818 may be in the initial open configuration as shown in FIG.

[0135] The manufacturing method may include moving the flip-top lid 1822 from an initial open position ( FIG. 32A ) to a closed position ( FIG. 32B ) after removing or withdrawing the closure cap 1818 from the molding die. The flip-top lid 1822 may pivot about the hinge 1819 from the initial open position ( FIG. 32A ) to the closed position ( FIG. 32B ), thereby forming the closure cap 1818 in an initial closed configuration. As the flip-top lid 1822 moves from the initial open position to the closed position, the first and second extending tabs 1885, 1885′ and the first and second breakable members 1825, 1825′ generally move along with the movement of the flip-top lid 1822. When the flip-top lid 1822 is moved to the initial closed position, the first and second engagement protrusions 1882, 1882′ snap into position beneath the top surface of the peripheral step 1864 and pass through the entrances of the first and second receiving openings 1888, 1888′, thereby securely fastening the first and second extending tabs 1885, 1885′ to the base 1820. When the flip-top lid 1822 is in the closed position, the first and second flanges 1883, 1883′ are disposed on the top surface of the peripheral step 1864. In some embodiments, the first and second flanges 1883, 1883′ may be disposed in recesses 1887, 1887′ in the top surface of the peripheral step 1864 and in corresponding recesses 1886, 1886′ in the recessed sidewall 1853.

[0136] 33 is a partial perspective view from below the top surface of the peripheral step 1864 showing the first engagement protrusion 1882 after initial closure of the flip-top lid 1822, according to some embodiments. As shown in FIG. 33, the locking tab of the engagement protrusion 1882 engages with the underside of a recess 1887 adjacent the receiving opening 1888 to lock the receiving opening 1888.

[0137] FIG. 34 is a perspective view illustrating a subsequent opening configuration of the closure cap 1818, according to some embodiments. In some embodiments, the flip-top lid 1822 may be moved from a closed position to an open position after initial closure. In use, force applied to the flip-top lid 1822 by a user or other object causes the flip-top lid 1822 to pivot or hinge from the initial closed position ( FIG. 31 ) to a subsequent open position ( FIG. 34 ). Because the extending tabs 1885, 1885′ are secured to the base 1820 via engagement between the engaging projections 1882, 1882′ and the walls of the base 1820 adjacent the receiving openings 1888, 1888′, this action breaks, separates, severs, or damages the breakable member 1825 rather than removing the extending tabs 1885, 1885′ from the base 1820. At least a portion of the broken breakable member 1825, 1825' may remain attached to the flip-top lid 1822 and / or the extending tab 1885, 1885', indicating that the flip-top lid 1822 has previously been opened.

[0138] In some embodiments, the positions of the first and second extending tabs 1885, 1885' are reversed between the flip-top lid 1822 and the base 1820, so that in an initial closed configuration, the first and second extending tabs 1885, 1885' extend from / couple to the base 1820 via the breakable members 1825, 1825' and are secured / engaged to the flip-top lid using the engaging protrusions 1882, 1882'. In such embodiments, the first and second extending tabs 1885, 1885' are separated from the base 1820 when the flip-top lid 1822 is moved from the initial closed position to a subsequent open position.

[0139] Figures 35-39 illustrate another closure cap 1918 according to some embodiments. Figure 35 is a perspective view showing the closure cap 1918 in an initial open configuration. Figure 36 is a perspective view showing the closure cap 1918 in an initial closed configuration.

[0140] In some embodiments, the closure cap 1918 includes a base 1920, a flip-top lid 1922 hingedly connected to the base 1920, one or more extending tabs 1985, 1985', and one or more breakable members 1925, 1925'. The flip-top lid 1922 is movable between an open position (FIGS. 35 and 39) and a closed position (FIG. 36). The flip-top lid 1922 and the base 1920 form a recess 1970 in an outer wall of the closure cap 1918 when the flip-top lid 1922 is in the closed position.

[0141] The extending tabs may include a first extending tab 1985 and a second extending tab 1985′. The first extending tab 1985 may be positioned near a first side edge of the mouth-shaped opening of the recess 1970, and the second extending tab 1985′ may be positioned near a second side edge of the mouth-shaped opening of the recess 1970.

[0142] The first and second extending tabs 1985, 1985' may be coupled to the flip-top lid 1922 via breakable members 1925, 1925' in the initial open and initial closed configurations. The first extending tab 1985 may be coupled to the flip-top lid 1922 via the first breakable member 1925, and the second extending tab 1985' may be coupled to the flip-top lid 1922 via the second breakable member 1925'. The first and second extending tabs 1985, 1985' may be coupled to ends of the sidewall 1999 of the flip-top lid 1922.

[0143] In some embodiments, the first extending tab 1985 may include a first flange 1983 extending from the flip-top lid 1922 prior to initial opening and a first engagement protrusion 1982 extending from the first flange 1983. Similarly, the second extending tab 1985' may include a second flange 1983' extending from the flip-top lid 1922 prior to initial opening and a second engagement protrusion 1982' extending from the second flange 1983'.

[0144] In one embodiment, the first and second engagement projections 1982, 1982' may extend from the inner surfaces of the first and second flanges 1983, 1983' and may be substantially perpendicular to the first and second flanges 1983, 1983' (see FIG. 35).

[0145] In some embodiments, the first breakable member 1925 may be disposed on an edge of the first flange 1983 that faces the flip-top lid 1922, and the second breakable member 1925' may be disposed on an edge of the second flange 1983' that faces the flip-top lid 1922. As described above, the first and second breakable members 1925, 1925' connect the first and second extending tabs 1985, 1985' to the flip-top lid 1922 in the initial open and initial closed configurations, respectively. The first and second breakable members 1925, 1925' are configured to break when the flip-top lid 1922 is moved from an initial closed configuration to an open configuration, such that the first and second extending tabs 1985, 1985' and the flip-top lid 1922 may be separated when the flip-top lid 1922 is moved from the initial closed configuration to the open configuration.

[0146] In some embodiments, the extending tabs 1985, 1985' may be hinged to the flip-top lid 1922 (after initial molding and prior to opening the flip-top lid 1922 after initial closure), such that the extending tabs 1985, 1985' may pivot about the hinge connection due to their connection to the flip-top lid 1922. The hinge connection 1967, 1967' may be formed in a variety of ways. For example, the extending tabs 1985, 1985' may be formed from a flexible material that allows them to pivot about the hinge connection. The hinge connection 1967, 1967' may be located on or slightly above the breakable member 1925, 1925'. In one embodiment, the breakable member 1925, 1925' is hinged to the lid before being broken / cut.

[0147] Additionally, the base 1920 may have a first receiving opening 1988 and a second receiving opening 1988' in its sidewall 1997 (e.g., a sidewall of the peripheral step 1964). The first and second engagement protrusions 1982, 1982' are configured to engage with the base 1920 by being inserted through the first and second receiving openings 1988, 1988', respectively.

[0148] The sidewall 1997 of the base 1920 may have recesses 1987, 1987' around the first and second receiving openings 1988, 1988' for receiving the flanges 1983, 1983' of the extending tabs 1985, 1985'. One recess 1987 may be located near a first side edge of the mouth of the recess 1970, and the other recess 1987' may be located near a second side edge of the mouth of the recess 1970. In some embodiments, the recesses 1987, 1987' may extend from the upper surface of the peripheral step 1964.

[0149] As an example, the first and second engagement protrusions 1982, 1982′ may be configured to be easily pushed into the receiving openings 1988, 1988′ of the base 1920 but not pulled out or removed. For example, as shown in FIG. 35 , each of the first and second engagement protrusions 1982, 1982′ may include an elongated portion and a substantially hemispherical locking tab at its tip.

[0150] 37A-37C are side views illustrating the closure cap 1918 in as-manufactured, closed, and initial closed configurations. A method for manufacturing the closure cap 1918 may include molding the closure cap in a mold and ejecting the molded closure cap from the mold in an initial open configuration. The injected molded closure cap 1918 may be in the initial open configuration as shown in FIG. 35. In the initial open configuration, the extension tab may be pivoted outward about the hinge connection relative to the side wall 1999 of the flip-top lid 1922, as shown in FIGS. 35 and 37A.

[0151] The manufacturing method may include moving the flip-top lid 1922 from an initial open position to a closed position after extracting the closure cap 1918 from the mold. The flip-top lid 1922 may pivot about a hinge 1919 from the initial open position ( FIG. 37A ) to a closed position ( FIG. 37B ). In some embodiments, when the flip-top lid 1922 is moved to the closed position, the extension tab may be in an initial molded position pivoted outward relative to the sidewall 1999 of the flip-top lid 1922, as shown in FIG. 37B .

[0152] The manufacturing method may further include inserting the locking projections 1982, 1982' into receiving openings 1988, 1988' in the sidewall 1997 of the base 1920 such that the flanges 1983, 1983' are positioned in the recesses 1987, 1987' in the sidewall 1997 of the base 1920. The locking projections 1982, 1982' may be inserted into the receiving openings 1988, 1988' by rotating the extending tabs 1985, 1985' from an initial molded position to a final position in which the flanges 1983, 1983' of the extending tabs 1985, 1985' are substantially parallel to the sidewall 1999 of the closure cap 1918.

[0153] In some embodiments, an overcap molding or assembly cap 7 may be used to pivot the extension tabs 1985, 1985' from the initial molded position to the final position. The assembly cap 7 (shown in dashed lines in FIG. 37C ) may have an inner surface that corresponds to the shape of the sidewall of the closure cap 1918 in the initial closed configuration. In some embodiments, the extension tabs 1985, 1985' may be moved from the initial molded position to the final position by the closure cap 1918 and the assembly cap 7, for example, by sliding the assembly cap 7 over or forcing it into engagement with the closure cap. The assembly cap 7 may pivot the extension tabs 1985, 1985' from the initial molded position ( FIG. 37B ) to the final position ( FIG. 37C ) as the assembly cap 7 descends and passes the hinge connection 1967, 1967' connecting the extension tabs 1985, 1985' to the flip-top lid 1922. The closure cap 7 may be lowered until the locking projections 1982, 1982' are inserted into the receiving openings 1988, 1988' and the flanges 1983, 1983' are positioned in the recesses 1987, 1987' of the base 1920 so that the extending tabs 1985, 1985' are fixedly attached to the base 1920.

[0154] Figure 38 is a partial perspective view from the inside of peripheral step 1964 (e.g., the side wall of peripheral step 1964) after locking projection 1982 has been secured to base 1920. As shown in Figure 38, the locking pawl of locking projection 1982 engages with receiving opening 1988 by locking against the inner surface of recess 1987 near receiving opening 1988.

[0155] FIG. 39 is a perspective view illustrating a subsequent opening configuration of the closure cap 1918, according to some embodiments. In some embodiments, the flip-top lid 1922 may move from a closed position to an open position after initial closure. In use, the flip-top lid 1922 may pivot or hinge from an initial closed position ( FIG. 36 ) to a subsequent open position ( FIG. 39 ). Because the extension tabs 1985, 1985′ are fixedly attached to the base 1920 by the engagement of the locking projections 1982, 1982′ with the receiving openings 1988, 1988′ in the base 1920, this movement may break, separate, sever, or otherwise damage or fracture the frangible members 1925, 1925′ rather than removing the extension tabs 1985, 1985′ from the base 1920. According to one embodiment, pieces of the broken breakable member 1925, 1925' may still be attached to at least the flip-top lid 1922 and / or the extending tab 1985, 1985' and may provide an indicator that the flip-top lid 1922 has previously been opened.

[0156] 40-44 illustrate another closure cap 2018 according to some embodiments. FIG. 40 is a perspective view of the closure cap 2018 in an initial open configuration according to some embodiments. FIG. 41 is a perspective view of the closure cap 2018 in an initial closed configuration. FIG. 42 is a cross-sectional view of FIG. 40, and FIG. 42C is a cross-sectional view of FIG. 41.

[0157] In some embodiments, the closure cap 2018 includes a base 2020, a flip-top lid 2022 hingedly connected to the base 2020, a guide pole 2040 protruding from a top surface of the base 2020, a movable ring 2024, and one or more breakable members 2025. The flip-top lid 2022 is movable between an open position ( FIG. 40 ) and a closed position ( FIG. 41 ). The flip-top lid 2022 and the base 2020 form a recess 2070 in an outer wall of the closure cap 2018 when the flip-top lid 2022 is in the closed position.

[0158] The guide pole 2040 may protrude from the top surface of the base 2020. For example, the guide pole 2040 may protrude from a substantially flat portion 2062 of the top surface of the base 2020. In some embodiments, the guide pole 2040 may be disposed near the hinge connection 2019 connecting the flip-top lid 2022 and the base 2020. As shown in FIG. 42A , the guide pole 2040 may include a widened top end 2041 of the guide pole 2040 (which may be slightly wider than the portion of the guide pole 2040 adjacent to the widened top end 2041). For example, the guide pole 2040 may include a main post 2042 and an enlarged portion or widened top end 2041 disposed at the upper end thereof, and the widened top end 2041 may be slightly wider than the main post 2042.

[0159] In the initial open configuration, i.e., prior to initial closure, the movable ring 2024 is positioned in a notch 2024a (also shown in FIG. 44A ) in the top wall 2096 of the flip-top lid 2022. The movable ring 2024 may have a generally circular, donut-shaped, or annular shape. In some embodiments, the movable ring 2024 may have a flattened annular shape with an outer circumferential surface having an outer diameter and an inner circumferential surface having an inner diameter. The notch 2024a in the flip-top lid may correspond to the shape of the movable ring 2024. In some embodiments, the notch 2024a is slightly larger than the movable ring 2024, and there may be a slight gap between the movable ring 2024 and the notch 2024a.

[0160] After the initial closure of the flip-top lid 2022, the movable ring 2024 is positioned around the guide pole 2040 (see FIGS. 41, 43, and 44). After the initial closure and before subsequent opening of the flip-top lid 2022, the movable ring 2024 is fixed in a first position near or at the top of the guide pole 2040 (e.g., aligned with the top surface of the flip-top lid) and may not move because it is still attached to the flip-top lid 2022 via the breakable member 2025. After subsequent opening of the flip-top lid 2022 (e.g., after the breakable member 2025 is broken), the movable ring 2024 is movable from the first position to a lower second position. In some embodiments, when the movable ring 2024 is in the second position, the movable ring 2024 may be located below the wide top end 2041. For example, the movable ring 2024 may be in a first position when the flip-top lid 2022 is in an initial closed position and in a second position after the flip-top lid 2022 moves from the initial closed position to the open position. After a subsequent opening of the flip-top lid 2022, the movable ring 2024 may be movable between the first and second positions.

[0161] In the initial open configuration, the movable ring 2024 may be coupled to the flip-top lid 2022 via one or more breakable members 2025 disposed in a gap between the movable ring 2024 and the notch 2024a. The breakable members 2025 are configured to break when the flip-top lid 2022 is moved from the initial closed position (FIG. 41) to the subsequent open position (see FIG. 43). In some embodiments, the closure cap 2018 includes a plurality of breakable members forming spokes that couple the movable ring 2024 to the flip-top lid 2022 prior to initial opening. For example, in the initial open configuration (FIG. 40) and the initial closed configuration (FIG. 41), the plurality of breakable members 2025 couple the movable ring 2024 to the flip-top lid 2022, forming spokes around the periphery of the movable ring 2024 (see FIG. 41A).

[0162] 42 and 42C are cross-sectional views illustrating as-manufactured and initially closed configurations of a closure cap 2018 according to some embodiments.

[0163] A method of manufacturing the closure cap 2018 may include forming a molded closure cap in a mold and removing the closure cap from the forming mold in an initial open configuration, as shown in FIGS.

[0164] As shown in the detailed view of FIG. 42A, the guide pole 2040 may include a main post 2042 and an extension or wider top end 2041 disposed at the end of the main post 2042. According to one aspect, the extension or wider top end 2041 may be slightly wider than the main post 2042. In some embodiments, the sides of the extension or wider top end 2041 may be sloping, with the top surface being smaller than the bottom surface.

[0165] As shown in the detailed view of FIG. 42B , in some embodiments, the movable ring 2024 may include a step 2023 along the inner circumferential side 2014 of the movable ring 2024. In some configurations, the step 2023 is located near the inner surface of the top wall of the flip-top lid 2022. With reference to FIGS. 42C and 42D , the step 2023 may be formed on the lower part of the movable ring 2024 (e.g., extending from the lower surface of the movable ring 2024 that corresponds to the inner surface of the top wall 2096 of the flip-top lid 2022 prior to initial opening). For example, the lower surface of the step 2023 may be formed continuously with the lower surface of the remainder of the movable ring 2024. In some embodiments, the side of the step 2023 is sloped, such that the lower surface of the step 2023 protrudes less than the upper surface.

[0166] The manufacturing method may include moving the flip-top lid 2022 from an initial open position to a closed position after removing the closure cap 2018 from the molding die. The flip-top lid 2022 may pivot about the hinge 2019 to move from the initial open position ( FIG. 42 ) to the closed position ( FIG. 42C ), thereby forming the closure cap 2018 in an initial closed configuration. As the flip-top lid 2022 moves from the initial open position to the closed position, the movable ring 2024 and the breakable member 2025 move along with the movement of the flip-top lid 2022. As the flip-top lid 2022 moves to the initial closed position, the extension or widened top end 2041 passes through the shoulder 2023 of the movable ring 2024 and fits into the central hole of the movable ring 2024, such that the widened top end 2041 engages with the shoulder 2023 of the movable ring 2024. In other words, when the flip-top lid 2022 moves to the initial closed position, the shoulder 2023 passes over the wide upper end 2041. When the flip-top lid 2022 is in the initial closed position, the shoulder 2023 of the movable ring 2024 engages with the wide upper end 2041 of the guide pole 2040, so that the movable ring 2024 engages with the guide pole 2040.

[0167] In some embodiments, the step 2023 of the movable ring 2024 and the extension or wide top end 2041 of the guide pole 2040 are configured to easily pass each other as the flip-top lid 2022 is moved from the initial open position to the closed position, but not in the reverse direction. For example, as shown in the detailed view of FIG. 42D , the maximum inner diameter formed by the most protruding edge of the step 2023 can be slightly smaller than the diameter of the widest portion (e.g., the underside) of the wide top end 2041 of the guide pole 2040. Furthermore, the sides of the step 2023 and the wide top end 2041 are sloped in the same direction. The structure of the movable ring 2024 and the guide pole 2040 allows the movable ring to be retained around the guide pole after initial closure.

[0168] As described above, the movable ring 2024 is configured to be movable from a first position, in which the movable ring 2024 is located near or at the top end of the guide pole 2040, to a second position below the first position. When the flip-top lid 2022 is in the initial closed position, the movable ring 2024 can be located and fixed in the first position. When the movable ring 2024 is in the first position, the movable ring 2024 is located substantially flush with the top wall 2096 of the flip-top lid 2022, and the top surfaces of the flip-top lid 2022, the guide pole 2040, and the movable ring 2024 are substantially flat.

[0169] FIG. 43 is a perspective view of the closure cap 2018 in a subsequent opening configuration, according to some embodiments. In use, the flip-top lid 2022 may pivot or hinge from an initial closed position ( FIG. 41 ) to a subsequent opening position ( FIG. 43 ) after initial closure. The engagement of the shoulder 2023 with the extension or widened top end 2041 prevents the movable ring 2024 from disengaging from the guide pole 2040. Thus, movement of the flip-top lid 2022 from the initial closed position to the open position breaks, separates, severs, or damages the breakable member 2025 instead of separating the movable ring 2024 from the guide pole 2040. Pieces of the broken breakable member 2025 may remain in at least the notched surface of the movable ring 2024 and / or the flip-top lid 2022, indicating that the flip-top lid 2022 has previously been opened.

[0170] When the breakable member 2025 breaks, the movable ring 2024 separates from the flip-top lid 2022, allowing the movable ring 2024 to move from a first position to a second position, as shown in FIG. 43A. In some configurations, after the breakable member 2025 is severed, gravity may act on the movable ring 2024, causing further movement of the movable ring 2024. Thus, a loose, movable movable ring 2024 can also indicate that the flip-top lid 2022 has previously been opened.

[0171] 44 is a perspective view of the closure cap 2018 in a closed configuration following initial opening, according to some embodiments. As shown in FIG. 44, even if the flip-top lid 2022 returns to the closed position after initial opening, the movable ring 2024 can be in the second position. The movable ring 2024 in the second position can also indicate that the flip-top lid 2022 has previously been opened.

[0172] 45A and 45B are plan views illustrating additional variations 2018a and 2018b of the closure cap 2018, according to some embodiments. In certain aspects, the closure caps 2018a and 2018b may include first and second movable rings 2024 and 2024' and first and second guide poles 2040 and 2040' corresponding to the first and second movable rings 2024 and 2024', respectively. In some embodiments, as shown in FIG. 45A, the first and second movable rings 2024 and 2024' and the first and second guide poles 2040 and 2040' may be positioned at the front of the closure cap, e.g., near the recess. In another embodiment, as shown in FIG. 45B, the first and second movable rings 2024, 2024' and the first and second guide poles 2040, 2040' may be located at the rear of the closure cap, for example, near the hinge 2019.

[0173] Figures 46-49 illustrate another embodiment of a closure cap 2118 according to some embodiments. Figure 46 is a perspective view illustrating an initial open configuration of the closure cap 2118 according to some embodiments. Figure 47 is a perspective view illustrating an initial closed configuration of the closure cap 2118.

[0174] In some embodiments, the closure cap 2118 includes a base 2120 and a lid 2122. The lid 2122 includes a flip member 2123 hingedly connected to the base 2120 and a pair of side panels 2124. The pair of side panels 2124 includes a first side panel and a second side panel. The first side panel is disposed on a first side of the flip member 2123, and the second side panel is disposed on a second side of the flip member 2123. The flip member 2123 is movable between an open position (see FIGS. 46 and 49) and a closed position (FIG. 47). The side panels 2124 are secured to the base 2120 when the closure cap 2118 is initially closed. The lid 2122 and base 2120 form a recess 2170 in the outer wall of the closure cap 2118 when the lid 2122 (including the flip member 2123 and the first and second side panels 2124) is in the closed position.

[0175] In some embodiments, the closure cap 2118 includes a plurality of weakened portions or breakable members 2125. The flip member 2123 is coupled to the first and second side panels 2124 via the plurality of breakable members 2125 in the initial open position ( FIG. 46 ) and the initial closed position ( FIG. 47 ). The flip member 2123 is configured to separate from the side panels 2124 when moved from the initial closed position ( FIG. 47 ) to the subsequent open position ( FIG. 49 ). For example, when the breakable member 2125 is severed, the flip member 2123 separates from the side panels 2124.

[0176] In some embodiments, the breakable members 2125 are formed as bridges of material on the top surface of the lid. The breakable members 2125 may be disposed on the top surface of the lid. The bridges 2125 connect the flip member 2123 to the side panels 2124 prior to initial opening, i.e., in the initial open and initial closed configurations. The bridges 2125 are configured to break when the flip member 2123 is moved from the initial closed position to the open position.

[0177] In some embodiments, the base 2120 includes a central portion 2130 and a substantially flat portion 2162. The substantially flat portion 2162 and the surface of the base 2120 that forms the recess may extend around the periphery of the central portion 2130. The base 2120 may include a plurality of receiving openings 2188. The plurality of receiving openings may be disposed in an upper surface of the substantially flat portion 2162.

[0178] In some embodiments, the closure cap 2118 includes a plurality of engagement members 2140 extending from the lid 2122. The plurality of engagement members 2140 may extend from the inner surface of the top wall of the side panel 2124. For example, at least one engagement member may extend from each of the pair of side panels 2124. The engagement members 2140 may be disposed at positions corresponding to the receiving openings 2188 of the base 2120. The number of the plurality of engagement members 2140 may be the same as the number of the plurality of receiving openings 2188. In some embodiments, each engagement member 2140 includes a protrusion 2142 extending from the lid 2122 and a locking tab 2141 disposed at the end of the protrusion 2142.

[0179] Figures 48 and 48B are cross-sectional views showing as-manufactured and initially closed configurations of the closure cap 2118. Figure 48A is a partial detailed view of portion 48A of Figure 48, and Figure 48C is a partial detailed view of portion 48C of Figure 48B.

[0180] A method of manufacturing the closure cap 2118 may include forming a molded closure cap in a molding die and ejecting the molded closure cap in an initial-open configuration from the molding die. The injected molded closure cap 2118 may be in the initial-open configuration as shown in FIG. 46. During the molding process, a pair of side panels 2124 are integrally molded with the lid 2122. For example, the pair of side panels 2124 may be integrally molded with the flip member 2123.

[0181] According to one embodiment, the breakable member / bridge 2125 may be formed when the lid 2122 is molded. According to another embodiment, the breakable member / bridge 2125 may be formed through a post-molding process. For example, the breakable member / bridge 2125 may be formed by applying an instrument or tool, such as a mold, laser, or knife, to score or incis the interface between the flip member 2123 and the side panel 2124 without cutting the portion corresponding to the breakable member / bridge 2125. In the initial open configuration, the flip member 2123 and the side panel 2124 are connected by a plurality of breakable members 2125 formed by bridges on the top surface of the lid. In some embodiments, the interface of the flip member 2123 may be formed to display a company logo.

[0182] The manufacturing method may include moving the lid 2122 from an initial open position to a closed position after removing the closure cap 2118 from the mold. The lid 2122 may be pivoted about the hinge 2119 from the initial open position ( FIG. 48 ) to a closed position ( FIG. 48B ) to form the closure cap 2118 in the initial closed configuration. As the lid 2122 moves from the initial open position to the closed position, an engagement member 2140 extending from the side panel 2124 moves with the lid 2122. As the lid 2122 moves to the initial closed position, a locking claw 2141 of the engagement member 2140 is inserted into a corresponding receiving opening 2188 formed in the top wall 2161 of the base 2120, thereby locking the engagement member 2140 to the base 2120, and the insertion portion of the engagement member 2140 (e.g., the locking claw 2141) is positioned below the top wall 2161 of the base 2120. In this manner, the engaging members 2140 may be inserted into the corresponding receiving openings 2188 of the base 2120, thereby securing the side panel 2124 to the base 2120 upon initial closure. After initial closure, the locking pawl 2141 may be positioned below the top wall 2161 of the base 2120, adjacent the corresponding receiving opening 2188 in the base 2120. In some embodiments, the locking pawl 2141 may have a ledge or other structure that prevents it from being pulled out of the base 2120 after initial closure. In some embodiments, the maximum width of the locking pawl 2141 may be slightly wider than the width of the narrowest portion 2186 of the corresponding receiving opening 2188, which may prevent the locking pawl 2141 from being pulled out of the base 2120 after initial closure.

[0183] In some embodiments, the pawl 2141 may have a beveled surface that facilitates passage through the corresponding receiving opening 2188. Additionally, in some embodiments, the pawl 2141 may have a tip with a width that is less than or equal to the width of the widest portion 2189 of the corresponding receiving opening 2188, thereby facilitating passage of the pawl 2141 through the corresponding receiving opening 2188.

[0184] 49 is a perspective view of the closure cap 2118 in a subsequent open configuration, according to some embodiments. In some embodiments, during use, force applied to the flip member 2123 by a user or other object may cause the flip member 2123 to pivot or hinge from an initial closed position ( FIG. 47 ) to a subsequent open position ( FIG. 49 ). Because the side panel 2124 is fixedly coupled or secured to the base 2120 by engagement of the engagement members 2140 extending from the side panel 2124 with the receiving openings 2188 in the base 2120, this movement of the flip member 2123 will separate, cut, or otherwise damage or break the breakable member 2125 instead of pulling the engagement members 2140 from the base 2120 and removing the side panel 2124 from the base 2120. Furthermore, breaking or separating the breakable member 2125 only leaves a slit, line of weakness, or cut that extends to the portion that is secured to the remainder of the closure cap, and therefore does not result in a piece that breaks away from the remainder of the flip member 2123 or side panel 2124. Nevertheless, a broken breakable member indicates that the lid 2122, and therefore the flip member 2123, has already been opened.

[0185] Figures 50-57 illustrate other closure caps 2218, 2318, 2418, and 2518 according to some embodiments. Figures 50-57 primarily illustrate variations in the breakable member. The closure caps can have ribs, no ribs, or other textured exterior surfaces. For example, Figures 50, 52, 54, and 56 include multiple ribs that allow a user to manually grip and manipulate the closure cap. While Figures 51, 53, 55, 57A, and 57B do not show ribs, ribs may be added as shown in Figures 50, 52, 54, and 56.

[0186] The breakable member structures and features shown here may also be incorporated into other closure cap embodiments described herein.

[0187] Figure 50 is a perspective view of another closure cap 2218 in an initial closed configuration, according to some embodiments. Figure 51 is a perspective view of the closure cap 2218 in a partially open configuration after initial closure.

[0188] The closure cap 2218 may include multiple breakable members. For example, the closure cap 2218 may include a first breakable member 2225a, a second breakable member 2225b, and a third breakable member 2225c. As shown in FIG. 50 , when the closure cap 2218 is in the initial closed configuration, the breakable members 2225a, 2225b, and 2225c connect one element (e.g., the inset wall 2291) to another element (e.g., the extending tab 2285).

[0189] In some embodiments, at least one breakable member may be misaligned with the others, for example, the second breakable member 2225b is offset from the first and third breakable members 2225a, 2225c, and the second breakable member 2225b is positioned above the first and third breakable members 2225a, 2225c.

[0190] The breakable members 2225a, 2225b, 2225c are configured to break when the flip-top lid 2222 is moved from an initial closed position to an open position, and as shown in FIG. 51, after breaking, the breakable members still remain attached to at least one of the elements that were connected together before breaking.

[0191] Figure 52 is a perspective view of a closure cap 2318 in an initial closed configuration according to one embodiment of the present invention, and Figure 53 is a perspective view of the closure cap 2318 in a partially open state after initial closure.

[0192] The closure cap 2318 may include multiple breakable members. For example, the closure cap 2318 may include a first breakable member 2325a, a second breakable member 2325b, and a third breakable member 2325c. As shown in FIG. 52 , in this embodiment, the closure cap 2318 may further include a pair of interference flanges 2326a, 2326b, which may be disposed between the breakable members 2325a, 2325b, 2325c, i.e., between the first and second breakable members 2325a, 2325b and between the second and third breakable members 2325b, 2325c.

[0193] The breakable members 2325a, 2325b, 2325c are configured to break when the flip-top lid 2322 is moved from an initial closed position to an open position. As shown in FIG. 53, the broken breakable members 2325a, 2325b, 2325c remain with at least one of the elements that interconnected them prior to breaking.

[0194] The interference flanges 2326a, 2326b may be configured to interfere with movement of the flip-top lid 2322. In this embodiment, the interference flanges 2326a, 2326b may deform when the flip-top lid is moved from a closed position to an open position (e.g., when the flip-top lid 2322 is opened from an initially closed state).

[0195] Figure 54 is a perspective view of a closure cap 2418 in an initial closed configuration according to one embodiment of the present invention, and Figure 55 is a perspective view of the closure cap 2418 in a partially open state after initial closure.

[0196] The closure cap 2418 may include a first breakable member 2425a, a second breakable member 2425b, and a third breakable member 2425c. As shown in FIG. 55, the first, second, and third breakable members 2425a, 2425b, and 2425c may each be formed elongated. In this embodiment, the second breakable member 2425b, which is disposed between the first and third breakable members 2425a and 2425c, may be formed more elongated than the first and third breakable members 2425a and 2425c.

[0197] The breakable members 2425a, 2425b, and 2425c are configured to break when the flip-top lid 2422 is moved from an initial closed position to an open position. The breakable members 2425a, 2425b, and 2425c may deform due to forces applied to them before ultimately breaking. In this embodiment, as shown in FIG. 55, the amount of deformation of the second breakable member 2425b may be greater than the amount of deformation of the first and third breakable members 2425a and 2425c.

[0198] Figure 56 is a perspective view of a closure cap 2518 in an initial closed configuration according to one embodiment of the invention, Figure 57A is a perspective view of a closure cap 2518 in a partially open configuration following the initial closed configuration according to one embodiment of the invention, and Figure 57B is a perspective view of a closure cap 2518 in a closed configuration following the initial open configuration according to one embodiment of the invention.

[0199] The closure cap 2518 may include one or more breakable members 2525a, 2525b, and 2525c. As shown in FIG. 56 , when the closure cap 2518 is in an initial closed state, the breakable members 2525a, 2525b, and 2525c connect one element (e.g., the extending tab 2585) to another element (e.g., the inset wall 2591). In this embodiment, when the extending tab 2585 is connected to the inset wall 2591 via the breakable members 2525a, 2525b, and 2525c, the extending tab is spaced apart from the surface directly below it. In other words, before the breakable members are broken, a gap exists between the extending tab and the surface directly below it (e.g., the surface of the base 2520).

[0200] When the breakable members 2525a, 2525b, 2525c break when the flip-top lid 2522 is initially moved from the closed position to the open position, the extending tab 2585 may drop downward until it contacts a lower surface (see FIG. 57A). The extending tab 2585 may remain in the dropped position in subsequent closed states, even after the flip-top lid 2522 is reclosed (see FIG. 57B), allowing a user to see a gap between the broken portions of the breakable members 2525a, 2525b, 2525c, which may indicate that the flip-top lid 2522 has previously been opened. Additionally, this gap may improve the visibility of the tamper-evident indicator.

[0201] Figure 58 illustrates various stages of the breakable member, including securing the extending tab in a lowered position and separating or breaking the breakable member to position the extending tab in a lowered position after the breakable portion of the extending tab is separated from the breakable member. This process proceeds according to the steps indicated by the arrows in Figure 58. As shown in the first view of Figure 58, in the initial closed configuration, the extending tab 2685 is connected to the inset wall 2691 via the breakable member 2625. The locking tab 2689 of the extending tab 2685 is inserted into the receiving opening 2687 and engages with the arms 2621, 2622 of the receiving opening 2687. As shown in the second and third views of FIG. 58, when the inset wall 2691 is pulled up, the engagement of the locking pawl 2689 with the arms 2621, 2622 prevents the extending tab 2685 from moving with the inset wall 2691, thereby breaking the breakable member 2625. For example, when a user opens a flip-top lid, the inset wall 2691 may be pulled up. The extending tab 2685 is then pushed down and clears the lower arms 2623, 2624, with the entire extending tab positioned below the receiving opening 2687, as shown in the fourth view of FIG.

[0202] 59A-59C are cross-sectional views of other locking projections 2785a, 2785b, and 2785c according to some embodiments.

[0203] 60-61 show another closure cap 2818 according to some embodiments. FIG. 60 is a perspective view of the closure cap 2818 in an initial open configuration according to some embodiments. FIG. 61 is a partial perspective view of the closure cap 2818 as viewed from the inside of the base according to some embodiments. FIG. 60A is a partial detailed view of portion 60A of FIG. 60. FIG. 61A is a partial detailed view of portion 61A of FIG. 61.

[0204] In some embodiments, the closure cap 2818 includes a base 2820 and a flip-top lid 2822. The flip-top lid 2822 may have an inset wall 2891 and an extending tab 2885 extending from the inset wall. The extending tab 2885 may include, for example, a notch 2886 in its center. The base 2820 has a receiving opening 2888 for receiving the extending tab 2885. The base 2820 further has a locking flange 2889 extending from a side of the receiving opening 2888.

[0205] 61 and 61A, the locking flange 2889 extends from a side (e.g., a front side) of the receiving opening 2888 toward the interior of the base 2820 (i.e., below the receiving opening 2888). For example, the locking flange 2889 may extend diagonally toward the interior of the base 2820.

[0206] 62 is a cutaway or partial perspective view illustrating an engagement mechanism between the extending tab 2885 and the locking flange 2889 of the base 2820, according to some embodiments. When the flip-top lid 2822 moves from an initial open position to a closed position, the inset wall 2891 and the extending tab 2885 may move with the movement of the flip-top lid 2822. As shown in FIG. 62, when the extending tab 2885 moves downward in response to the movement of the flip-top lid (FIG. 62 shows a portion of the inset wall 2891, but for purposes of illustration, the entire flip-top lid is not shown), the locking flange 2889 may engage with the extending tab 2885 by snapping into the notch 2886 of the extending tab 2885.

[0207] Figures 63A-63D show a variation of the closure cap 2818 of Figure 62. Figures 63A-63D are cutaway or partial perspective views showing the engagement mechanism between the extending tab 2885 and the locking flange 2889 in a first position, and the mechanism for securing the extending tab 2885 in a second position.

[0208] 63A-63D, the extending tab 2885 includes a first notch 2886a and a second notch 2886b. The second notch 2886b may be disposed between the first notch 2886a and the breakable member 2825. When the flip-top lid 2822 moves from an initial open position to an initial closed position, the inset wall 2891 and the extending tab 2885 may move with the movement of the flip-top lid 2822 (a portion of the inset wall 2891 is shown in FIGS. 63A-63D, but the entire flip-top lid is not shown for purposes of illustration). 63A and 63B, when the flip-top lid 2822 moves from the initial open position to the initial closed position, the locking flange 2889 may engage with the extending tab 2885 by snapping into the first notch 2886a of the extending tab 2885 as the extending tab 2885 moves downward together with the inset wall 2891. Referring to FIG. 63C, when the flip-top lid moves from the initial closed position toward the open position and the inset wall 2891 moves upward, the breakable member 2825 between the inset wall 2891 and the extending tab 2885 breaks, and the extending tab 2885 separates from the inset wall 2891. As shown in FIG. 63C, when the breakable member 2825 breaks, the extending tab 2885 is in a first position with the locking flange 2889 engaged in the first notch 2886a. In some embodiments, a portion of the extending tab 2885 protrudes from the recess-forming surface of the base 2820 when the extending tab 2885 is in the first position, which can cause inconvenience when a user accesses the recess to open the flip-top lid. According to this embodiment, by further depressing the extending tab 2885 after the flip-top lid is initially opened, the extending tab 2885 is positioned in the second position where the locking flange 2889 engages with the second notch 2886b (see FIG. 63D ). Because the extending tab 2885 in the second position is positioned lower than the extending tab 2885 in the first position, the extending tab 2885 in the second position presents less of an obstacle when a user accesses the recess than the extending tab 2885 in the first position.In some embodiments, the extending tab 2885 in the second position is positioned entirely below the recess forming surface to minimize interference with access to the recess.

[0209] As shown in FIG. 63D, even if the flip-top lid 2822 returns to the closed position after the extension tab has moved to the second position, a gap between the inset wall and the extension tab typically remains, which can improve the visibility of the tamper-evident feature that indicates that the flip-top lid 2822 has already been opened.

[0210] Waste, particularly plastic, is an increasingly serious problem, and because small pieces of material are typically unsuitable for recycling, it is advantageous to minimize or completely eliminate small pieces that may become detached or shed from packaging. Small pieces of plastic are of particular concern, as they may find their way into waterways, food systems, and other sensitive environments. Therefore, it is desirable that small pieces of plastic not be removed, shed, or separated from larger pieces of plastic, which are generally easier to recycle. As shown herein, in accordance with the present disclosure, small pieces of the closure cap necessary to form the above-described tamper-evident structures, such as extension tabs, breakable members, and movable rings, remain part of the closure cap during use and do not separate, even after the closure cap is opened.
