Description

[0001] Cross-reference of related applications

[0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 916,545, filed on October 17, 2019, entitled “Bottle screw caps and methods for making and using the same,” the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The currently disclosed technology generally relates to screw caps for providing a moisture-proof seal on bottles. More specifically, in one embodiment, the currently disclosed technology relates to screw caps with a resilient seal that provides sufficient closure integrity to eliminate the need for a heat-sealed closure to maintain the shelf life of the contents of the bottle. Background Technology

[0004] For example, commercially available medicine containers for tablets and capsules are typically provided as glass or plastic bottles with removable caps (often with some form of child-resistance). Over-the-counter (OTC) pain relievers, allergy medications, and supplements and vitamins are often stored in these bottles. Generally, the complexity and corresponding cost of these containers increase with their moisture-proof capabilities.

[0005] Typically, to ensure the contents of a bottle are not tampered with, a flexible seal (usually composed of foil, paper, flexible / thin plastic, cardboard, or a composite of one or more of these) provides a tight, airtight seal to the container opening. If a user wishes to access the contents, they can permanently puncture or at least partially remove the seal. An intact seal protects the container's contents from environmental influences and provides the user with a visual indication that the container has not been tampered with.

[0006] Depending on the nature of the contents of the container, desiccants or other active materials may be required to control the environment inside the container. Typically, desiccants are provided in the form of small packets or cylindrical containers, which are loosely placed inside the container along with its contents.

[0007] Containers as described above are typically filled via automated processes. Tamper-proof seals, such as foil seals, are often applied to cover the container opening after filling. Various methods and means of securing seals are known, such as via adhesives or heat. The most common method for applying seals is inductive sealing. Inductive sealing is a process that relies on an electric current within a material such as foil and / or cardboard to generate heat. Inductive sealing and other sealing methods require specialized equipment and materials in the filling line. These types of seals are often necessary to maintain the shelf life of the container's contents.

[0008] Not all filling lines have inductive sealing devices, and foil seals are not always necessary. Therefore, there is a need for a bottle and cap assembly that provides the required shelf life for the contents of the bottle without requiring foil seals.

[0009] Furthermore, in cases requiring foil seals, the bottle's moisture resistance is compromised once the seal breaks (after initial use), even if a cap is replaced. Regular bottle caps do not offer a moisture-proof seal. Summary of the Invention

[0010] There is a need to manufacture improved screw caps for bottles, as described above. Currently disclosed technologies address these and other needs.

[0011] In one aspect, the currently disclosed technology is directed to provide a screw-on cap for a bottle assembly. The cap includes a body having a base, an annular skirt hanging downwards from the periphery of the base, and at least one internal flexible lip sealing member hanging downwards from the base. The lip sealing member is concentrically disposed internally relative to the annular skirt. The annular skirt has internal threads configured to engage corresponding threads on an outer portion of the bottle neck in a screw-on manner. The cap may optionally include a thermoplastic elastomer sealing member disposed on the base around its entire periphery, the thermoplastic elastomer sealing member being configured to engage and seal with an end portion of the bottle neck. The at least one internal flexible lip sealing member is configured to engage and seal with an inner or outer surface of the bottle neck.

[0012] In another aspect, the currently disclosed technology is directed to a bottle assembly comprising a bottle and the aforementioned screw cap. Attached Figure Description

[0055] While systems, apparatuses, and methods are described herein with the aid of examples and embodiments, those skilled in the art will recognize that the currently disclosed technology is not limited to the described embodiments or figures. Furthermore, the currently disclosed technology covers all modifications, equivalents, and alternatives falling within the spirit and scope of the appended claims. Features of any embodiment disclosed herein may be omitted or incorporated into another embodiment.

[0056] Any headings used herein are for organizational purposes only and are not intended to limit the scope of the specification or claims. As used herein, the word “may” is used in an permissible sense (i.e., meaning possibly) rather than a mandatory sense (i.e., meaning must). Unless specifically stated herein, the terms “a / an” and “the” are not limited to a single element but should be interpreted as meaning “at least one.” These terms include the words mentioned above, their derivatives, and words with similar meanings.

[0057] As used in this article, “and / or” means referring to any one or both of the items separated by this term. For example, the phrase “A and / or B” would mean only A, only B, or both A and B.

[0058] As used herein, the expression “linked” to two or more parts or components means that the parts are directly joined together or operate together, or indirectly joined together or operate together, i.e., through one or more intermediate parts or components, provided that a link exists.

[0059] As used herein, “directly connected” means that two elements are in direct contact with each other. As used herein, “fixedly connected” or “fixed” means that two components are connected so as to move as a whole while maintaining a constant orientation relative to each other.

[0060] As used herein, the word "around" in phrases such as "surrounding [an element, point, or axis]", "extending around [an element, point, or axis]", or "around [an element, point, or axis] [X] degrees" means to enclose, extend around, or measure around. When referring to a measurement or used in a similar manner, "about" means "approximately," that is, within the approximate range relevant to the measurement, as will be understood by one of ordinary skill in the art.

[0061] As used in this article, “generally speaking” means “in a general manner” in relation to the project being modified, as will be understood by someone generally skilled in the art.

[0062] As used herein, the term “monolithic” means that a component is formed as a single (optionally monolithic) piece or unit. That is, an component that comprises pieces that are formed separately and then joined together as a unit is not a “monolithic” component or body.

[0063] As used herein, the expression “engage” between two or more parts or components means that the parts are applied to each other directly or through one or more intermediate parts or components.

[0064] As used in this article, the term “number” will mean an integer of one or more (i.e., multiple).

[0065] As used in this article, the phrase “sealed engagement” or “sealed engagement” refers to components coming into contact with each other such that a generally moisture-proof seal is formed between them.

[0066] As used herein, directional terms such as top, bottom, left, right, upper, lower, front, back, and their derivatives refer to the orientation of the elements shown in the figures and are not limiting of the claims unless expressly stated in the claims.

[0067] Generally, as used herein, the term "moisture-proof" is defined as the presence of less than 1500 μg of water ingress (after three days), less than 500 μg of water in another embodiment, less than 300 μg of water in yet another embodiment, and less than 150 μg of water in still another embodiment, as determined by the following test method: (a) placing 1 gram plus or minus 0.25 g of molecular sieve in a container and recording the weight; (b) completely closing the container; (c) placing the closed container in an environmental chamber at 80% relative humidity and 72°F; (d) weighing the container containing the molecular sieve after one day; (e) weighing the container containing the molecular sieve after four days; and (f) calculating the moisture ingress into the container in micrograms of water by subtracting the sample from the sample from the sample on the fourth day. The preferred rate of moisture ingress into the moisture-proof sealed container produced according to one aspect of the disclosed concept is in the range of approximately 200-300 μg of water or less per day. Therefore, a "moisture-proof" seal is a sealing engagement that, alone or in combination with additional sealing engagements, contributes to making the container "moisture-proof" in accordance with the above definition.

[0068] As used herein, the term “resealable” means that the lid of a container can be opened or reopened and closed or reclosed many times (e.g., more than 10 times) while still maintaining its moisture-proof properties.

[0069] Please refer to the figures for details. The same reference numerals in the figures always refer to the same parts. Figure 1-2BVarious views of a container and cap assembly, generally designated 10, are shown. The container and cap assembly 10 includes a bottle 12 and a screw cap 14 removably and securely attached thereto. While the bottle 12 depicted in the figures represents a carefully considered type of container that can be used in conjunction with the currently disclosed technology, other types of containers are also carefully considered. It should be understood that while the term "bottle" is used to describe exemplary embodiments, the broader and more general term "container" may also be used alternatively. The bottle is optionally made of plastic or glass.

[0070] Bottle 12 may include a body 16 having a base 18 and one or more sidewalls 20 extending upward therefrom, the one or more sidewalls opening into a rim 22 surrounding an upper opening 24 of bottle 12. The illustrated embodiment is cylindrical and therefore has a single circular sidewall 20. However, containers according to the disclosed concept may have other shapes, such as cuboids, and therefore have more than a single continuous (e.g., circular) sidewall.

[0071] See Figure 2A The rim 22 may include an upper engaging surface 26. The bottle 12 may include a neck 28 having one or more threads 30 for providing threaded engagement with corresponding or complementary threads 32 of the cap 14 when the cap 14 is secured to the bottle 12. The body 16 of the bottle 12 may define an interior space 34 configured to store contents therein, such as multiple pharmaceutical or health product tablets, capsules, or powders, or solid or liquid products from the food, pharmaceutical, or chemical industries (not shown). The interior space 34 is accessible via an opening 24.

[0072] Now see Figure 2A and 2B The cover 14 may include a base or top portion 40 and an annular skirt 42 hanging downwards from its outer periphery. Optionally, the top portion 40 may be flat or planar. The skirt 42 may include threads 32 as described above in its inner portion or on its surface.

[0073] In one embodiment, the lid 14 is optionally made primarily of one or more injection-molded thermoplastic materials comprising, for example, polyolefins (e.g., polypropylene or polyethylene).

[0074] For some applications, child-proof lids may be necessary, but not for all applications. Therefore, child-proof lids and non-child-proof lids should be carefully considered. If a child-proof feature is provided, it optionally requires applying force in more than one direction to the lid to remove it from the container. For example, the lid may require the user to press down (in the first direction) before rotating it (in the second direction) to remove it from the container. Alternative child-proof features should also be carefully considered as needed.

[0075] Optionally, the lid 14 may include a bottom side 52 attached to or integral with the top portion 40, or an active polymer component 50. The active polymer component 50 may comprise a base polymer carrying one or more active agents, and therefore may be referred to herein as an active agent-carrying polymer or a polymer-carrying polymer. The active agents in the active polymer component 50 may comprise absorbent materials, release materials, and / or activating materials. Optionally, the active polymer component 50 is a three-phase polymer carrying a desiccant. The active polymer component 50 may be configured in various shapes, volumes, and / or arrangements. In the exemplary embodiments shown, the active polymer component 50 is in the form of a solid plug or a generally planar component extending into the interior space of the lid 14.

[0076] In one embodiment, the active polymer component 50 is a desiccant-encased polymer, which is a monolithic component made of a single material. The encased polymer, whether encasing a desiccant or another active agent, may comprise a base polymer (for structure), a desiccant (or other active agent), and optionally a pore-forming agent. These types of active encased polymers and methods of their manufacture and use are disclosed, for example, in U.S. Patent Nos. 5,911,937, 6,214,255, 6,130,263, 6,080,350, 6,174,952, 6,124,006, and 6,221,446, and U.S. Patent Publication No. 2016 / 0039955, the entire contents of which are incorporated herein by reference. Alternatively, the encased polymer may be in the form of a loosely or optionally thermally supported film on a surface.

[0077] Alternatively, the desiccant may comprise loose desiccant beads or a pouch containing loose desiccant beads. While the exemplary embodiments herein reflect the attachment of the active polymer component 50 to the cap 14, the active agent may, upon careful consideration, be located at other locations and / or positions, such as on the sidewalls of the body or neck.

[0078] In embodiments where each active component contains a desiccant, hygroscopicity is required. However, where hygroscopicity is not required, the active components may contain alternative active agents. For example, in another embodiment, the active component contains materials selected from the group consisting of activated carbon, carbon black, ketjen black, and diamond powder. In another embodiment, the active agent comprises one or more layers of the active component containing materials such as absorbent microspheres, BaTiO3, SrTiO3, SiO2, Al2O3, ZnO, TiO2, MnO, CuO, Sb2O3, silica, calcium oxide, and ion exchange resins. In yet another embodiment, the absorbent 116 containing the active component layer contains two or more types of absorbents. Suitable absorbents are selected to achieve the absorption of desired vapors or gases for the intended end use (e.g., absorption of moisture, oxygen, carbon dioxide, nitrogen, or other undesirable gases or vapors).

[0079] Active components (whether desiccants, oxygen scavengers, release materials, or components, or combinations thereof) are capable of acting on, interacting with, or reacting with selected materials (e.g., moisture or oxygen). Examples of such actions or interactions may include absorption, adsorption (typically adsorption), or release of the selected material. Each active component may be, for example, extruded or molded. Alternatively, active components may be formed into desired shapes or patterns (e.g., on a backing) via an in-line melt-bonding thermal bonding process.

[0080] The active component may comprise an "active ingredient" in the base material. The active ingredient (i) is immiscible with the base material (e.g., a polymer) and will not melt when mixed with the base polymer and a pore-forming agent and heated, i.e., has a melting point higher than the melting point of the base polymer or the pore-forming agent, and / or (ii) acts on, interacts with, or reacts with the selected material. The term "active ingredient" may include (but is not limited to) materials that absorb, adsorb, or release the selected material. According to the currently disclosed art, the active ingredient may be in the form of particles such as minerals (e.g., molecular sieves or silica gel in the case of desiccants), but the currently disclosed art should not be considered as limited to particulate active agents. For example, in some embodiments, the deoxygenating formulation may be made of a resin, which acts as an active agent or a component of an active agent.

[0081] As used herein, the term "base material" refers to a component (preferably a polymer) that provides the structure of the entrained active material, excluding the surfactant.

[0082] As used herein, the term "base polymer" is a polymer that optionally has a gas permeability substantially lower than, lower than, or substantially equivalent to that of a pore-forming agent. By way of example, in embodiments where the selected material is moisture and the active ingredient is a desiccant, this permeability would be water vapor permeability. The primary function of the base polymer is to provide the structure of the entrained polymer. Suitable base polymers may comprise thermoplastic polymers such as polyolefins (e.g., polypropylene and polyethylene, polyisoprene, polybutadiene, polybutene, polysiloxane, polycarbonate, polyamide, ethylene-vinyl acetate copolymer, ethylene-methacrylate copolymer, poly(vinyl chloride), polystyrene, polyester, polyanhydride, polyacrylonitrile, polysulfone, polyacrylate, acrylic acid, polyurethane, and polyacetal), or copolymers or mixtures thereof.

[0083] Referring to this comparison of the water vapor transmission rates of the base polymer and the channel forming agent, in one embodiment, the channel forming agent has a water vapor transmission rate at least twice that of the base polymer. In another embodiment, the channel forming agent has a water vapor transmission rate at least five times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate at least ten times that of the base polymer. In still another embodiment, the channel forming agent has a water vapor transmission rate at least twenty times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate at least fifty times that of the base polymer. In yet another embodiment, the channel forming agent has a water vapor transmission rate at least one hundred times that of the base polymer.

[0084] As used herein, the term "channeling agent" is defined as a material that is immiscible with a base polymer and has an affinity for transporting gaseous substances at a faster rate than the base polymer. Optionally, the channeling agent is capable of forming channels through an entrained polymer formed by mixing the channeling agent with the base polymer. Optionally, these channels are capable of transporting selected materials through the entrained polymer at a faster rate than the base polymer alone.

[0085] As used herein, the term “channel” or “interconnected channel” is defined as a pathway formed by a channel-forming agent that penetrates the base polymer and is interconnected with each other.

[0086] As used herein, the term "entrained polymer" is defined as a monolithic material formed of at least a base polymer with an active agent and optionally a channel-forming agent entrained or distributed therein. Entrained polymers thus include biphase polymers and triphase polymers. "Mineral-loaded polymer" is a type of entrained polymer in which the active agent is in the form of mineral particles, such as molecular sieves or silica gel. The term "entrained material" is used herein to refer to a monolithic material comprising an active agent entrained in a base material, which may be polymeric or non-polymeric.

[0087] As used herein, the terms “monolayer,” “monolayer structure,” or “monolayer composition” are defined as compositions or materials that do not consist of two or more discrete macrolayers or portions. Accordingly, a “monolayer composition” does not contain a multilayer composite.

[0088] As used herein, the term "phase" is defined as a portion or component of a monolithic structure or composition uniformly distributed therein to give the structure or composition its monolithic characteristics.

[0089] As used herein, the term "selected material" is defined as a material that acts on, is acted upon by, or interacts with or reacts with an active agent and is transportable through channels encapsulating a polymer. For example, in embodiments where a desiccant is used as the active agent, the selected material may be moisture or a gas that can be absorbed by the desiccant. In embodiments where a releasing material is used as the active agent, the selected material may be a reagent released by the releasing material, such as moisture, fragrance, or antibacterial agent (e.g., chlorine dioxide). In embodiments where an adsorbent material is used as the active ingredient, the selected material may be certain volatile organic compounds, and the adsorbent material may be activated carbon.

[0090] As used herein, the term "three-phase" is defined as a monolithic composition or structure comprising three or more phases. An example of a three-phase composition according to currently disclosed techniques would be an entrained polymer formed from a base polymer, an active agent, and a pore-forming agent. Optionally, a three-phase composition or structure may include an additional phase, such as a colorant.

[0091] The entrained polymer can be a two-phase formulation (i.e., comprising a base polymer and an active ingredient, without a pore-forming agent) or a three-phase formulation (i.e., comprising a base polymer, an active ingredient, and a pore-forming agent). Entrained polymers are described, for example, in U.S. Patents Nos. 5,911,937, 6,080,350, 6,124,006, 6,130,263, 6,194,079, 6,214,255, 6,486,231, 7,005,459, and U.S. Patent Publication No. 2016 / 0039955, each of which is incorporated herein by reference in its entirety.

[0092] The entrained material or polymer comprises a base material (e.g., a polymer) for providing the structure, optionally a pore-forming agent, and an active agent. The pore-forming agent forms microscopically interconnected channels through the entrained polymer. At least some of the active ingredient is contained within these channels, such that a channel communication is formed between the active ingredient and the exterior of the entrained polymer via the microscopic channel openings at the outer surface of the entrained polymer. The active ingredient may be, for example, any of a variety of absorbent, adsorbent, or release materials, as described in further detail below. While a pore-forming component is preferred, the currently disclosed techniques broadly include entrained materials, such as two-phase polymers, that optionally do not contain a pore-forming agent.

[0093] In any embodiment, a suitable pore-forming agent may comprise a polyethylene glycol (e.g., polyethylene glycol (PEG)), ethylene-vinyl alcohol (EVOH), polyvinyl alcohol (PVOH), glycerol polyamine, polyurethane, and a polycarboxylic acid comprising polyacrylic acid or polymethacrylic acid. Alternatively, the pore-forming agent may be, for example, a water-insoluble polymer, such as propylene oxide polymerized monobutyl ether, for example, Polyglykol B01 / 240 produced by CLARIANT. In other embodiments, the pore-forming agent may be propylene oxide polymerized monobutyl ether, for example, Polyglykol B01 / 20 produced by CLARIANT; propylene oxide polymerized product, for example, Polyglykol D01 / 240 produced by CLARIANT; ethylene vinyl acetate; Nylon 6; Nylon 66; or any combination thereof.

[0094] Suitable active ingredients according to currently disclosed techniques include absorbent materials, such as desiccant compounds. If the active agent is a desiccant, any suitable desiccant for a given application can be used. Generally, physical absorption desiccants are preferred for many applications. These may include molecular sieves, silica gel, clay, and starch. Alternatively, the desiccant may be a chemical compound that forms water-containing crystals, or a compound that reacts with water to form a new compound.

[0095] Optionally, in any embodiment, the activator may be an oxygen scavenger, such as an oxygen scavenging resin formulation.

[0096] See again Figure 2A and 2BTo provide a moisture-proof seal between the cap 14 and the bottle 12, the cap 14 may include a compressible seal 60 attached to or integral with at least a portion of the bottom side 52 of the top portion 40 of the cap 14. Optionally, the compressible seal 60 may be annular in shape, surrounding and optionally contacting the outer annular edge of the active polymer component 50. The compressible seal 60 may be made of an elastomer such as a thermoplastic elastomer (TPE). The formation of the compressible seal 60 is discussed in detail below.

[0097] When the cap 14 is secured to the bottle 12 to cover the opening 24, the compressible seal 60 contacts the upper engagement surface 26 of the rim 22. The engagement between the threads 32 and 30 on the neck 28 of the cap 14 secures the cap 14 tightly to the bottle 12, causing the compressible seal 60 to compress as it is pressed firmly against the upper engagement surface 26. This forms a moisture-proof seal between the cap 14 and the container 12.

[0098] like Figure 2B As shown, in one optional embodiment, upon sealing engagement, vertical compression of the compressible seal 60 causes a portion of it to elastically deform and radially expand into the gap 62 provided between the skirt 42 and the compressible seal 60. The presence of the gap 62 ensures that the compressible seal 60 is not constrained or obstructed by any structure on the side of the gap 62. Thus, when the compressible seal 60 is vertically compressed, a portion of it can elastically expand or migrate radially outward (…). Figure 2B (Centering to the left and right). The further the seal 60 is compressed downwards, the more it enters the gap 62. The gap 62 thus provides "living space" for the sealing material to expand radially during engagement. This radial expansion into the gap feature helps prevent excessive vertical spring force that could otherwise be generated. This spring force could unnecessarily cause wear on the threads 30, 32. The radial expansion into the gap feature also promotes an increase in the contact surface area between the corresponding sealing surfaces of the seal engagement. This helps to provide a more robust seal at the point of seal engagement.

[0099] Optionally, the outer radial surface 64 of the compression seal 60 may include a downward slope, such that the outer radial surface 64 is slightly radially outwardly oriented as it extends downward from the bottom side 52 of the top portion 40 of the cover 14.

[0100] According to currently disclosed technology, the cap 14 can be manufactured in a variety of ways. One method of forming or manufacturing the cap 14 includes injection molding. More specifically, one method of forming or manufacturing the cap 14 includes multi-injection injection molding.

[0101] See Figures 3A-3B In an optional embodiment, the cap 14 can be manufactured in a three-injection molding process. For example... Figure 3AIn the process illustrated, the first injection into the mold will be an active polymer component 50 (e.g., a polymer encapsulating a desiccant and a pore-forming agent). Figure 3B As shown, the second injection in the mold will be a compressible seal 60 (e.g., TPE). Figure 3C As shown, the third injection will be for the remainder of the cap (e.g., using a polyolefin material).

[0102] like Figures 3A-3B As shown, all steps of the three-ply injection process involve forming a mold assembly that creates cavities corresponding to the respective portions of the cap 14 to be manufactured. For example, all steps may involve the use of a common core 70. The first injection may involve using the common core 70 and an active polymer component mold portion 72 to form a cavity, thereby forming the active polymer component 50. The first injection is one of molten entrained polymers (e.g., desiccant plastic) injected at a first gate 74. The first gate 74 may be positioned directly above the molten entrained polymer. After the first injection, the active polymer component mold portion 72 may be replaced by a compressible seal mold portion 76. The second injection is one of molten thermoplastic elastomer materials injected at a second gate 78. Optionally, through this process, the polymer material in the active polymer component contacts and chemically bonds with the thermoplastic elastomer material. After the second injection, the compressible seal mold portion 76 is replaced by a cap mold portion 80. The third injection may be one of molten plastics (e.g., polypropylene or polyethylene) injected at a third gate 82. Alternatively, this process allows the cap material to come into contact with and chemically bond with both the compressible sealing material and the active polymer component material. In this way, the three components of the cap 14 are integrated into each other in the finished product.

[0103] In at least one embodiment, the disclosed concept avoids the need for foil seals or other types of heat-sealing materials above the opening for storage. The compression seal 60 is configured to provide sufficient closure integrity for the shelf life of the contents of the bottle 12 so that foil seals, etc., are not required.

[0104] Optionally, the tamper evidence mechanism is located on the cap. For example, an integral polymer tamper evidence ring, such as that commonly seen on water bottles, can be provided. During production, optionally after the process described above is performed and the cap 14 is injected from the mold, the molded tamper evidence ring can be placed directly onto the cap by a robot. Alternatively, a shrink seal can be provided above / around the cap.

[0105] Figure 4 and 5Another embodiment of the screw cap 102, illustrating the currently disclosed technology, is shown. The body 104 of the cap 102 may include a generally disc-shaped base 106 and an annular skirt 108 hanging downwards from its outer periphery. The skirt 108 may include one or more internal threads 110. The screw cap 102 may form part of a bottle assembly having a bottle 150. The bottle 150 may include a base, sidewalls 152 extending upwards therefrom, and an end portion or lip 154 ​​of a neck positioned opposite the base and distal to the base. The end portion 154 may define an opening leading to the interior of the bottle 150. The internal threads 110 of the body 104 may be configured to engage corresponding threads on the end portion 154 of the bottle 150 in a screwable manner.

[0106] See again Figure 5 The cap 102 optionally includes at least one and possibly two spaced-apart internal flexible lip sealing members 114, 116, which are suspended downward from the base 106 and concentric with respect to the annular skirt 108 and internally positioned. In one exemplary embodiment, the cap 102 includes two flexible lip sealing members 114, 116, each configured to be located on opposite sides of the neck of the bottle 150. Furthermore, in one exemplary embodiment, the internal flexible lip sealing members 114, 116 advantageously engage with the end portion 154 of the neck of the bottle 150 and form a moisture-proof seal.

[0107] Figure 6 and 7 Another embodiment of the screw cap 102, demonstrating the currently disclosed technology, is shown. For example... Figure 7 As shown, the cover 102 may optionally include a sealing member 120 located on and optionally on the inner surface of the base 106. The sealing member 120 may extend substantially around the entire periphery of the base 106. In one example embodiment, the sealing member 120 is a thermoplastic elastomer material. Figure 6 As shown, the substrate 106 may include a hole 107 extending therethrough and near the periphery of the substrate 106. The hole 107 provides a mechanism by which the sealing member 120 can be molded onto the substrate 106. Figure 6 When the cover 102 is viewed from the top, a portion of the sealing component 120 is visible through the hole 107.

[0108] Figure 8 Is with Figure 5 A view similar to the view, but Figure 8The sealing member 120 is incorporated within the cap 104. The sealing member 120 may contact, engage, and / or form a moisture-proof seal with the end portion 154 of the neck of the bottle 150. In one exemplary embodiment, the sealing member 120 is located between first and second flexible lip seals 114, 116. Accordingly, the cap and / or bottle assembly will include three sealing protection points (e.g., between the inner and outer surfaces of the neck and the lip seals 114, 116, and between the end portion 154 of the neck and the sealing member 120), which allows the bottle assembly 100 to provide an improved ability to prevent moisture from entering (e.g., but not limited to) the medication contained within the bottle 150.

[0109] Figure 9 and 10 Another embodiment of the bottle assembly 200 according to the currently disclosed technology is shown. The bottle assembly 200 is generally similar to the bottle assembly 100 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0110] like Figure 10 As shown, the cap 202 may include a single internal flexible lip sealing member 216. Additionally, the cap 202 may include an annular retaining protrusion 218 that extends from the base 206 and is concentric with and internally positioned relative to the single lip 216. Figure 9 and 10 As shown, the retaining protrusion 218 is not configured to engage the neck of the bottle 250, and the sealing member 220 may be located between the single lip sealing member 216 and the retaining protrusion 218.

[0111] Figure 11 and 12 Another embodiment of the bottle assembly 300 according to the currently disclosed technology is shown. The bottle assembly 300 is generally similar to the bottle assembly 100 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0112] like Figure 12 As shown, the cap 302 may include a single lip sealing member 316 configured to engage with the neck of the bottle 350 and form a moisture-proof seal. Furthermore, the cap 302 may include an inner surface 307 configured to face the interior of the bottle 350. Figure 11 As shown, the sealing member 320 may have a circular or disc-shaped shape, and the sealing member 320 may be attached to and cover the inner surface 307 of the cover 302.

[0113] Figure 13 and 14 Another embodiment of the bottle assembly 400 according to the currently disclosed technology is shown. The bottle assembly 400 is generally similar to the bottle assembly 100 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not limiting and does not imply the absence of a certain feature or component in this embodiment.

[0114] like Figure 13 As shown, the sealing member 420 may include an annular portion 422 and a linear portion 424 extending across the annular portion 422. The annular portion 422 may be located on the underside of the cover 402. Figure 14 As shown, the annular portion 422 engages with the end portion 454 of the bottle 450 and forms a seal, such as a moisture-proof seal. The linear portion 424 extends across the cap 402 and below the geometric center of the cap 402.

[0115] Figure 15 and 16 Another embodiment of the lid 502 according to the currently disclosed technology is shown. The lid 502 is generally similar to the lid 302 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0116] The cover 502 may include an annular skirt 508 and at least one retaining feature 509. Optionally, the retaining feature 509 is in the form of a projection extending radially inward from the annular skirt 508. In one embodiment, the projection 509 may be formed or be in the shape of a semi-domed dome. The retaining feature 509 may be located at or near the free end of the annular skirt 508. Optionally, the retaining feature 509 may be located at or near the free end of the annular skirt 508.

[0117] Now see Figure 17-19 , Figure 15 and 16 The cap 502 shown can be designed to work with the bottle 550 to form the bottle assembly 500. For example... Figure 17As shown, bottle 550 may include a base 551, sidewalls 552 extending upward therefrom, and an end portion 554 of a neck positioned opposite to and distal from the base 551. Optionally, the end portion 554 of bottle 550 may include one or more engaging or retaining features 556. In one embodiment, the engaging or retaining feature 556 may be in the form of a protrusion or stud extending vertically and / or connecting two portions of a threaded connection of bottle 550. Optionally, the engaging or retaining feature 556 may be in the shape of a semi-domed dome.

[0118] See Figure 19 The retaining feature 509 of the cap 502 is configured to contact and / or pass over the engagement or retaining feature 556 of the bottle 550 when the cap 502 is attached to the bottle 550. This interference can form a latching mechanism, a tactile mechanism, and / or an auditory mechanism or response. For example, in one embodiment, once the retaining feature 509 of the cap 502 rotates to initially engage or contact with the engagement or retaining feature 556 of the bottle 550, continued rotation of the cap 502 causes the retaining feature 509 of the cap 502 to latch over and / or above the engagement or retaining feature 556 of the bottle 550. This movement and the resulting tactile and / or auditory sensations that the user can feel and / or hear will provide an additional mechanism by which the user will know that the cap 502 is properly and / or fully secured (e.g., sealed) to the bottle 550.

[0119] Figure 20A and 20B Another embodiment of the lid 602 according to the currently disclosed technology is shown. The lid 602 is generally similar to the lid 502 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0120] The cover 602 may include a retaining mechanism 609 at a location different from the retaining mechanism 509 of the cover 602. For example, the retaining mechanism 609 is located at or near the vertical midpoint of the annular skirt 608 of the cover 602. Optionally, the retaining mechanism 609 may have, for example... Figure 20A The cross-section is a triangle or roughly triangular shape as shown in the diagram. In one embodiment, the retaining mechanism 609 may be formed by two linear surfaces meeting at a point. Optionally, the two linear surfaces may form an angle of approximately 60 degrees between them, or optionally an angle of 40-80 degrees between them.

[0121] Furthermore, compared to the cover 502 of the previous embodiment, the annular skirt 608 of the cover 602 may include a second portion 608b that is radially outwardly spaced from the first portion 608a. Therefore, the annular skirt 608 may include portions extending in two different vertical planes. The retaining mechanism 609 may be configured to, for example... Figure 17 and 18 The corresponding engagement or holding mechanism of the bottle shown in the image forms a snap-fit ​​engagement.

[0122] Figure 21A and 21B Another embodiment of the lid 702 according to the currently disclosed technology is shown. The lid 702 is generally similar to the lid 602 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not limiting and does not imply the absence of a certain feature or component in this embodiment.

[0123] The retaining mechanism 709 of the lid 702 may be larger, wider, thicker, and / or extend further radially inward from the inner surface of the annular sidewall 708 than the retaining mechanism 609 of the lid 602. Optionally, the retaining mechanism 709 may be formed by two linear surfaces meeting at a point. Optionally, the angle between the two linear surfaces may be exactly or approximately 90 degrees. The end of the vertical linear surface of the two linear surfaces opposite the horizontal linear surface of the two linear surfaces may have an arcuate shape.

[0124] Figure 22A-22G Another embodiment of the lid 802 according to the currently disclosed technology is shown. The lid 802 is generally similar to the lid 702 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0125] The cover 802 may include one or more recesses, cutouts, or grooves 880 in a portion of the annular skirt 808. Optionally, at least one of the cutouts 880 may be located on the outer surface of the cover 802 and may optionally extend over or from a first portion 808a of the annular skirt 808 to a second portion 808b.

[0126] In an optional embodiment, the cover 802 may include a passage 882 extending therethrough. Optionally, the passage 882 may be sized, shaped, and / or configured to fit at least partially or completely within the cutout 880. The passage 882 may optionally extend completely through at least a portion of the cover 802, for example (but not limited to) through at least a portion of the annular skirt 808 and / or the sidewall of the cover 802.

[0127] Optionally, the passage 882 may have a generally C-shaped, generally U-shaped, and / or generally L-shaped. More specifically, in at least one embodiment, the passage 882 is not circular or cylindrical in shape, but extends along two, three, or more axes (at least two of which are perpendicular to each other).

[0128] Compared to Figure 20A , 20B The embodiments shown in 21A and 21B include sidewalls of recess 880 and / or passage 882 configured as annular skirt 808 and / or cap 802, increasing structural flexibility. This increased flexibility facilitates desired interaction between retaining feature 809 and the relevant portion of the bottle to produce an audible response (e.g., a “click” sound) when cap 802 is rotated relative to the bottle.

[0129] like Figure 22E and 22F As shown, in an optional embodiment, the cap 802 and / or skirt may include a tampering evidence feature 884. The tampering evidence feature 884 may take any of a variety of forms. For example, alternatively, the tampering evidence feature 884 may be in the form of a tab configured to block and / or engage at least a portion of the bottle 850, such as the engagement or retention feature 556 discussed above. Therefore, in order to remove the cap 802 from the bottle 850 and / or rotate the cap 802 relative to the bottle 850 by a predetermined amount, the tampering evidence feature 884 must be at least partially removed, broken, and / or separated from the skirt 808 of the cap 802.

[0130] Optionally, in one embodiment, one or more (e.g., two or four) bridging elements, links, or extensions 886 may connect the body 888 of the tampered evidence feature 884 to the skirt 808. In one embodiment, such as Figure 22F As shown, each extension 886 may extend parallel to the bottom surface of the skirt 808. However, one or more extensions 886 may be oriented in different ways, such as perpendicular to the bottom surface of the skirt 808 or at an angle relative to the bottom surface of the skirt 808. The body 888 may be rectangular in shape, such as... Figure 22F As shown. However, the main body 888 is not limited to this configuration or shape. For example, the main body 888 may be elliptical, circular, square, triangular, etc. Optionally, in addition to the one or more extensions 886, there may be gaps or intervals between the main body 888 and the rest of the skirt 808 surrounding the periphery of the main body 888.

[0131] In operation, at least one of the extensions 886 is configured to at least partially separate, break, or abrade (with either or both of the body 888 and the skirt 808) when at least a portion of the body 888 of the tamper evidence feature 884 moves sufficiently past or over a portion of the bottle (e.g., a protrusion on the neck). Optionally, if the cap 802 is not rotated a sufficient distance or with sufficient force, none of the extensions 886 will abrade, and the tamper evidence feature 884 will indicate that the cap 802 has not been opened.

[0132] In one embodiment, at least the body 888 of the altered evidence feature 884 may extend above or from the first portion 808a of the skirt 808 to the second portion 808b. Optionally, the body 888 may be positioned below the end of the skirt 808 attached to the base and above the relatively free end of the skirt 808. Optionally, the body 888 may be positioned at a distance from the second free end of the skirt and toward the first end of the skirt.

[0133] These configurations differ from the characteristics of conventional milk carton tampering evidence located at or beyond the free end of the skirt 808.

[0134] At least a portion of the tampering evidence feature 884, such as a portion of its body 888, may extend radially outward beyond the skirt 808. Optionally, the cap 802 may not be rotatable relative to the bottle 850 unless and until the tampering evidence feature 884 breaks or fractures. Once the tampering evidence feature 884 is removed or sufficiently broken (e.g., wear in one of the extensions 886), the cap 802 is permitted to rotate fully and / or completely relative to the bottle 850.

[0135] In another embodiment, tamper evidence feature 884 may include a tear feature commonly seen on plastic milk cartons. Alternatively, tamper evidence feature 884 may be a film or plastic ring that surrounds at least a portion of the cap 802, unless and until the film or plastic ring breaks or ruptures when the cap 802 is moved a predetermined amount relative to the bottle 850.

[0136] The currently disclosed techniques can utilize tamper-evident features with or without foil seals, which are commonly used to enclose the contents of a container and are located at the top opening of the container. In one embodiment, the tamper-evident features described herein can be used instead of foil seals, which can simplify and / or reduce the cost of manufacturing and / or filling processes while still providing the user with insight into whether the contents of the container have been previously received. Therefore, in this embodiment, the tamper-evident features of the currently disclosed techniques render conventional foil seals unnecessary.

[0137] Figures 23A-23CAnother embodiment of the lid 902 according to the currently disclosed technology is shown. The lid 902 is generally similar to the lid 802 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only certain obvious differences between the two embodiments will be discussed herein for the sake of brevity and convenience. This is not restrictive and does not imply the absence of a certain feature or component in this embodiment.

[0138] Compared to the cutout 880 and passage 882 of the cover 802, one difference from the cover 902 is the shape, configuration, and / or extent of the cutout 980 and passage 982. The cutout 980 optionally forms at least partially a recess in the outer surface of the skirt 908. Optionally, the width of the recess is optionally at least slightly smaller than the width of the passage 982.

[0139] Figure 24A-2 A 3D illustration shows another embodiment of the lid 1002 according to the currently disclosed technology. The lid 1002 is generally similar to the lid 802 discussed above. Thus, the same reference numerals will be used to indicate the same components, and only for the sake of brevity and convenience will some obvious differences between the two embodiments be discussed herein, which is not limiting and does not imply the absence of a certain feature or component in this embodiment.

[0140] Compared to the passage of cover 802, one difference from cover 1002 is the shape, configuration, and / or extent of passage 1082. For example, passage 1082 may be rotated ninety degrees relative to the orientation of the embodiment described above. A first segment of passage 1082 may be located in a first portion 1008a of skirt 1008, and a second segment of passage 1082 may be located in a second portion 1008b of skirt 1008. Optionally, the longitudinal axis of the first segment may extend parallel to the longitudinal axis of the second segment.
