Description

This application is a divisional application based on Chinese patent application filed on September 3, 2024, with application number 202411227973.9 and invention title "Overflow-free straw". Cross-references to related applications

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 529,125 entitled "No Spill Straw," filed July 26, 2023, and U.S. Provisional Application No. 63 / 529,988 entitled "No Spill Straw," filed July 31, 2023. Technical Field

[0002] The aspects described in this article relate to portable beverage accessories, such as insulated travel mugs, shaker cups, and the like. Background Technology

[0003] Travel beverage accessories typically include insulated and non-insulated cups, double-walled cups, or any other suitable beverage container that includes a fitted lid to prevent accidental spills. The lid can be a simple screw cap or a push-button cap, and may not always be leak-proof. Leak-proof lids are presumably designed to include mechanisms that typically require two hands to operate, and therefore can be cumbersome to use. Summary of the Invention

[0004] At a high level, the beverage container may include a lid structure coupled to a base structure to define an internal volume for holding and / or dispensing a beverage held within the container. The base structure may be a cup-shaped container, optionally insulated to keep the beverage hot / cold for an extended period (e.g., between 4 and 48 hours). The lid structure may have a spout portion or straw mechanism for dispensing the contents of the beverage container when the lid structure and the base structure are engaged. To provide a leak-proof beverage container, the straw mechanism is rotatably switchable between a closed state (i.e., non-dispensing state, non-overflowing state, travel state, or unused state) and an open state (i.e., dispensing state). When in its closed state, the straw mechanism prevents the contents of the beverage container from spilling or otherwise dispensing or consuming from the beverage container. When in its open state, the straw mechanism allows the contents of the beverage container to be consumed or otherwise dispensed from the beverage container.

[0005] The cap structure according to aspects described herein includes a straw mechanism and a body portion. The body portion has: a threaded engagement section configured to securely engage the base structure of the beverage container; and an engagement cavity configured to receive and engage the straw mechanism, as will become more apparent in the description with reference to the accompanying drawings provided below. The straw mechanism and the body portion are detachably engaged to facilitate cleaning of the cap structure. Furthermore, the straw mechanism and the body portion are rotatably engaged to provide a leak-proof cap structure for travel or general portability. This is superior to conventional straw-based beverage containers where the straw extends through a permeable opening in the cap, or where the straw itself is an open conduit to the contents of the container, both of which are potential leakage areas.

[0006] This document generally relates to a lid structure for a beverage container having a body portion including a straw connector configured to detachably attach to a detachable straw. Among other things, the detachable straw facilitates thorough cleaning of the lid structure and also provides a container that can be neatly stored within the internal volume defined by the base structure and the lid structure.

[0007] The straw mechanism of the cap structure includes a frame portion and a nozzle portion having a nozzle opening. In one embodiment, by way of non-limiting example, the nozzle portion may be rigid and formed of a hard polymer, plastic material, metal, or other rigid material. In another embodiment, by way of non-limiting example, the nozzle portion may be flexible (i.e., bendable, stretchable, elastic, deformable) and formed of a suitable material (e.g., silicone or other rubber polymer material). The frame portion frames the nozzle portion such that the nozzle portion extends outward through the opening of the frame portion and a first surface of the frame portion. Furthermore, the first surface of the frame portion includes a first indicator projecting from the first surface. A nozzle base portion is wider than the nozzle portion and sits on a second surface of the frame portion, thereby sealing the opening of the frame portion. The nozzle opening of the nozzle portion extends through to the nozzle base portion. In some aspects, the shape of the nozzle portion is similar to that of a conventional straw with a cylindrical tubular structure having a circular cross-section with a circular opening. In other aspects, by way of non-limiting example, the nozzle portion may have a tubular structure having any desired cross-sectional shape, and the desired cross-sectional shape having an opening of a corresponding shape, such as a triangle, a star, a square, etc. In other aspects, by way of non-limiting example, regardless of the cross-sectional shape of the nozzle portion, the opening may always be half a shape (e.g., a semicircle, a semi-star, a semi-triangle, a semi-square, etc.). However, in a preferred embodiment, the nozzle base portion may always have an opening of half a shape. In other words, if the nozzle has a circular opening, then the nozzle base portion may have a semi-circular opening.

[0008] The second surface of the frame portion further includes a first annular magnet housing projecting from the second surface, the first annular magnet housing accommodating an annular magnet. Furthermore, the outer surface of the annular magnet housing forms a key with a first ridge and a second ridge extending circumferentially around the magnet housing, respectively. The first ridge has a first length different from the second ridge's second length. The edge of the second surface of the frame portion further includes a ridge aligned with the first indicator on the first surface of the frame portion and a notch positioned opposite to the ridge.

[0009] The engagement cavity of the main body portion of the cover structure is configured to engage with the straw mechanism by receiving the magnet housing, such that the first surface of the frame portion of the straw mechanism is flush with the outer surface of the cover structure when engaged with it. The main body portion of the cover structure forms a second annular magnet housing projecting from the inner surface of the main body portion. This second annular magnet housing accommodates a second annular magnet having the opposite polarity to the first annular magnet, thereby generating a strong attraction between the frame portion of the straw mechanism and the main body portion of the cover structure. The engagement cavity includes a first lip and a second lip, which form a keyhole in the main body portion, ensuring that the straw mechanism is always received by the main body portion in a predetermined configuration. Furthermore, the main body portion includes several stop tongues to lock the straw mechanism's rotation along a 180° path. The second annular magnet is contained within the second annular magnet housing via the cover portion. The cover portion has a semi-circular opening configured to align with the semi-circular opening of the tube base portion. This ensures that when the semicircular opening at the base of the nozzle and the semicircular opening at the cap are aligned, there is flow from the nozzle portion, and when the semicircular opening at the cap and the semicircular opening at the nozzle are not aligned (i.e., on opposite sides), there is no flow from the nozzle portion.

[0010] The aspects herein generally relate to a beverage container comprising a base structure and a lid structure having a magnetic straw mechanism. The base structure may be composed of a double-walled plastic structure, a glass or polymer-based structure, or an insulating structure made of stainless steel, aluminum, copper, or any other suitable material or combination of materials suitable for insulating the contents of the beverage container from external temperature fluctuations for an extended period. The base structure according to the aspects herein includes an outer wall and an inner wall. The inner wall of the base structure includes a threaded portion adjacent to the opening edge of the base structure. A stepped edge is provided in the inner wall of the base structure, defining the end point of the threaded portion and the beginning point of the unthreaded portion of the inner wall, wherein the unthreaded portion of the inner wall extends inward toward a relative center of the container further than the internally threaded segment of the base structure. Optionally, the inner wall may include a volume marker configured to signal the volume contained within the base structure when it is filled with beverage. The volume of the base structure can be sized and shaped to be maintained between 14 oz. of beverage and 100 oz. of beverage.

[0029] An overview of the features, functions, and / or configurations of the components depicted in the figures will now be presented. It should be understood that it is not necessary to describe all features of the components in the figures. Some of these undiscussed features (e.g., various couplings, etc.) as well as the features discussed, are inherent to the figures themselves. Other undiscussed features may be inherent to the geometry and / or configuration of the components. Detailed Implementation

[0030] The subject matter of embodiments of the invention has been specifically described herein to satisfy legal requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have anticipated that the claimed subject matter may also be embodied in other ways, in combination with other current or future techniques, including different features or combinations of features similar to those described herein. Furthermore, it should be understood that the drawings do not necessarily represent an all-encompassing representation of the embodiments herein and may have various hidden components to aid in their written description.

[0031] At a high level, it was made public such as Figure 1 The beverage system 100 shown is a lid structure 102 and a base structure 104, which are main components. The beverage system may optionally further include a handle 106 for carrying the beverage system 100. Figure 1As further shown, the cap structure 102 may have a main body portion 108 and a straw mechanism 110. The straw mechanism 110 has a nozzle portion 112 with a nozzle opening 118 through which a user can drink fluid contained in the beverage system 100. The straw mechanism 110 further includes a frame portion 114. The nozzle portion 112 extends through an opening 116 in the frame portion 114 such that it extends through a first surface (outer surface) of the frame portion 114 and extends above the first surface (outer surface) of the frame portion 114. The frame portion may also include a first indicator 120 that guides the user to different positions or states of the straw mechanism 100, such as a dispensing state (e.g., [dispensing state]). Figure 9 and Figure 10 As shown), locked state or overflow prevention state (such as...) Figure 11 and Figure 12 (as shown in the image) and disassembled or cleaned state (as shown in the image) Figure 7 and Figure 8 As shown in the image).

[0032] The main body portion 108 of the cap structure 102 may include a second indicator 122 complementary to the first indicator 120. When aligned, the first indicator 120 and the second indicator 122 indicate, for example, that the straw mechanism 110 is in its dispensing state. Furthermore, the main body portion 108 includes a vent 124 to allow proper air circulation within the beverage system 100 as the contents are drawn from the base structure 104 when the user drinks from the spout portion 112, thereby ensuring or maintaining proper flow of liquid through the spout opening 118 of the spout portion 112. As shown, the base structure 104 of the beverage system 100 may optionally include a handle 106 to facilitate transport of the beverage system 100 by the user. Furthermore, as... Figure 2 As shown, the beverage system 100 may further include an anti-slip mat 200 on the base or bottom of the base structure 104 to help prevent the beverage system 100 from sliding across flat surfaces, such as countertops, tables, and the like. Exemplary materials that can be used for the anti-slip mat 200 may include, for example, natural rubber, synthetic rubber, rubber-treated silicone resin, thermoplastic polyurethane, polyurethane, neoprene rubber, nitrile rubber, and any other suitable material having the properties desired by the anti-slip mat 200.

[0033] Figure 3A partially disassembled beverage system 100 is depicted. As shown, the main body portion 108 and the straw mechanism 110 are separable to facilitate cleaning of the components of the beverage system 100, and specifically, cleaning of the cap structure 102. As shown, the main body portion 108 includes a recess or engagement cavity 308 to receive components of the straw mechanism 110, such that the outer surface of the frame portion 114 and the outer surface of the main body portion 108 are flush with each other during assembly, as previously described... Figure 1 As shown in the diagram. Furthermore, as shown, the straw 302, having a straw handle 314, is shown attached to the main body portion 108. (As shown in...) Figure 4 , Figure 5A and Figure 5B As can be seen more clearly, the straw mechanism 110 has a magnetic connection, wherein the second surface of the frame portion 114 has a first magnet housing 318 protruding from its inner surface or the second surface and accommodating the first magnet 802 (as shown in the image). Figure 8 (As shown in the diagram). The first magnet 802 may be annular, thus extending within and around the circumference of the first magnet housing 318, which may also be annular. Figure 4 As shown, the port base portion 410, located within a cavity formed at the center of the first magnet housing 318, includes a semi-circular opening 412. The second surface (i.e., the inner surface) of the frame portion 114 further includes a protrusion 402 directly opposite to the first indicator 120 on the first surface of the frame portion. Directly opposite to the protrusion 402, the frame portion 114 includes a recess 400 on its second surface. As shown in... Figures 5A to 5C and Figures 9 to 12 It will become more apparent that when the straw mechanism 110 is in the dispensing state, the notch 400 aligns with the vent seal 300, and when the straw mechanism 110 is in the sealing state, the protrusion 402 aligns with the vent seal 300 to seal the vent 124 by substantially blocking the opening of the vent seal 300.

[0034] The volume of the base structure 104 can be sized and shaped to hold between 14 oz. and 100 oz. of liquid beverage. The base structure 104 can consist of a double-walled plastic structure, glass, or a polymer-based material structure, or an insulating structure made of stainless steel, aluminum, copper, or any other suitable material or combination of materials suitable for insulating the contents of the beverage container from external temperature fluctuations for an extended period. The base structure 104 includes an inner wall 330 and an outer wall 332. The inner diameter of the inner wall 330 is generally smaller than the outer diameter of the outer wall 332, thereby providing a thickness between the inner wall 330 and the outer wall 332 for the base structure 104. This thickness can help provide insulating properties to the base structure 104 to prevent rapid cooling, rapid warming, and / or moisture seepage when containing cold or iced liquid beverages. In addition, to improve gripping and / or gripping comfort, the base structure 104 may optionally include a handle 106, which may or may not have additional friction surfaces coated or otherwise covered with rubber, such as, for example, natural rubber, synthetic rubber, rubber-treated silicone, thermoplastic polyurethane, polyurethane, neoprene, nitrile, and any other suitable material with desired properties.

[0035] Also Figure 4 As shown, the frame portion 114 further includes a first ridge 404 and a second ridge 406, which protrude from the first magnet housing 318 to form the "key" portion of the straw mechanism 110, and the engagement cavity 308 forms the "lock" portion of the cap structure through an opening having a first lip extension 304 and a second lip extension 306, or conversely, a first lip notch 322 and a second lip notch 324. The first ridge 404 has a first length, and the second ridge 406 has a second length different from the first length. The first lip notch 322 also has a first length, and the second lip notch 324 also has a second length. Thus, the straw mechanism 110 can be fitted into the engagement cavity 308 in only one predetermined manner (i.e., the first ridge 404 passes through the first lip notch 322, and the second ridge 406 passes through the second lip notch 324), as will become more apparent from the remaining figures.

[0036] like Figure 3 , Figure 4 , Figure 6A and Figure 6BAs further shown, the vent seal 300 may be made of a flexible rubber or silicone material with an opening, through which air can flow when unsealed. The first lip extension 304 and the second lip extension 306 are further equipped with stop tongues 320, configured to limit rotation of the straw mechanism 110 relative to the body portion 108 to 180° (i.e., a semi-circular path). The body portion 108 further includes threads 328 securing the cap structure 102 to the base structure 104. The base structure includes threads 326 complementary to the threads 328 on its inner wall 330 defining an internal volume 316. As shown, the base structure 104 has an internal volume 316 in which a beverage can be contained.

[0037] like Figure 8 , Figure 10 and Figure 12 As will become more apparent, the main body portion 108 houses the second magnet 804 within a engagement cavity 308, which is secured and covered by a cover portion 310. The cover portion 310 includes a second semi-circular opening 312, which works in conjunction with a semi-circular opening 412 of the nozzle base portion 410 to form a straw mechanism 110. The straw mechanism 110 is capable of transitioning between a dispensing state and a closed state (sealed state). The straw mechanism 110 is in the dispensing state when the semi-circular openings 312 and 412 are aligned with each other. Conversely, the closed state occurs when the semi-circular openings 412 and 312 are not aligned with each other (directly opposite to each other).

[0038] Figure 7 A beverage system 100 in an unlocked state 700 is shown. When in the unlocked state 700, the first indicator 120 is located at a quarter turn of the straw mechanism 110 between the second indicator 122 and the vent 124, or in other words, at a point 90° clockwise from the second indicator 122. (As shown in...) Figure 8 As better shown in the diagram, the first ridge 404 is aligned with the first lip notch 322, and the second ridge 406 is aligned with the second lip notch 324, such that the straw mechanism 110 can be pulled out from or separated from the main body portion 108 of the cap structure 102, as previously illustrated. Figure 3 and Figure 4 As shown in the illustration. By way of example, removing the straw mechanism 110 from the main body 108 facilitates access to the area of ​​the cap structure 102 located below the straw mechanism 110 for cleaning. As described above and in Figure 8As further shown in the cross-sectional view 800, the first magnet housing 318 houses the first magnet 802, which, when the straw mechanism 110 is within the engagement cavity 308, aligns with a second magnet 804 housed within the engagement cavity 308 and secured in place by the cover portion 310. The first magnet 802 and the second magnet 804 have opposite polarities, causing them to attract each other strongly and remain magnetically held even in the unlocked state 700, giving the user better control over the components and preventing them from loosening on their own. The user must perform a pulling motion on the straw mechanism 110 to pull it away from the body portion 108.

[0039] As shown, in Figure 8 In this configuration, the first magnet 802 is secured within the first magnet housing 318 by an elastic washer 806. Furthermore, the cover portion 310 is sealed by elastic seals 808 and 810, thereby effectively securing the second magnet 804 within the main body portion 108. As shown, when the straw mechanism 110 is within the engagement cavity 308, the first magnet 802 and the second magnet 804 are aligned with each other. According to aspects herein, it is contemplated that each of the first magnet 802 and the second magnet 804 is a one-piece annular magnet. According to other aspects, the first magnet 802 and the second magnet 804 may be open-loop, or in other words, bow-shaped rather than annular. The first bow-shaped magnet may occupy at least 50% of the first magnet housing 318, and the second magnet 804 may also be bow-shaped to match the shape of the first magnet 802. Alternatively, the bow-shaped magnets may be smaller, each occupying, for example, less than 50% of the first magnet housing 318. In such an embodiment, two or more arcuate magnets may be present at different locations within the first magnet housing 318, each occupying at least 10% of the first magnet housing 318. The arcuate magnets within the engagement cavity 308 can then be made to match the arcuate magnets within the first magnet housing 318. As further shown, when the straw 302 is connected to the body portion 108, the straw fitting 1402 of the body portion 108 is configured to fit within the straw opening 814, which is located within the straw connection port 1302. The straw connection portion 1302 defines a socket 1306, as shown in the figure below. Figure 13 The details will become more apparent. When connected, the straw 302 and the body portion 108 are sealed by an elastic washer 812.

[0040] Figure 9A beverage system 100 is shown in a locked and dispensing state 900. When in the locked and dispensing state 900, the first indicator 120 is rotated counterclockwise from the detachable state 700, as indicated by arrow 902, to align the first indicator 120 and the second indicator 122. In other words, the straw mechanism 110 is rotated counterclockwise by a quarter turn from the unlocked state, such that the first indicator 120 is positioned at a 0° rotation point from the second indicator 122. Figure 10 As better shown in the cross-sectional view 1000, the first ridge 404 is aligned with the second lip extension 306, and the second ridge 406 is aligned with the first lip extension 304, such that the straw mechanism 110 is locked within the engagement cavity 308 and therefore cannot be separated from the main body portion 108 of the cap structure 102. In the locked and dispensing state 900, a connecting opening 1006 is formed, in which the nozzle opening 118, the semi-circular opening 412, the semi-circular opening 312, and the straw opening 814 are all aligned with each other, thereby allowing the contents within the internal volume 316 to flow freely through the connecting opening 1006. When the contents are emptied, air can be drawn in from the vent 124, which has a vent seal 300 with a vent opening 301. This prevents the formation of a vacuum within the internal volume 316, which would make it increasingly difficult for the contents to be drawn through the nozzle portion 112. As shown, the notch 400 of the frame portion 114 is aligned with the vent seal 300 so as not to obstruct airflow through the vent opening 301.

[0041] Figure 11 A beverage system 100 in a locked and undispensed state 1100 is shown. When in the locked and undispensed state 1100, the first indicator 120 is rotated clockwise from the detachable state 700 as indicated by arrow 1102, to position the first indicator 120 and the second indicator 122 on opposite sides of each other, or in other words, at a point 180° from the second indicator 122. Figure 12 As better shown in the cross-sectional view 1200, the first ridge 404 is aligned with the first lip extension 304, and the second ridge 406 is aligned with the second lip extension 306, such that the straw mechanism 110 is also locked within the engagement cavity 308 and therefore cannot be separated from the main body portion 108 of the cap structure 102. In the locked and undistributed state 1100, a disconnected opening 1202 is formed, wherein the semicircular openings 412 and 312 are not aligned with each other (i.e., on opposite sides of each other), thereby blocking flow from the straw opening 814 to the nozzle opening 118. In addition, the protrusion 402 on the lower side of the frame portion 114 is aligned with the vent seal 300, thereby blocking the vent opening 301 of the vent seal 300, resulting in a blocked opening 1204, thereby effectively forming a leak-proof configuration.

[0042] Figure 13 A view 1300 of the straw assembly is shown. As shown, the straw 302 has a straw handle 314 with a straw tongue 1308. The straw 302 can be made of any suitable material that is safe to use (e.g., stainless steel, glass, silicone, bisphenol A (BPA) plastics, and the like). The handle 314 can be molded onto the straw 302, or can be manufactured as a single piece with the straw 302, or can be fitted onto the straw 302. The handle 314 can be made of the same material as the straw 302, or can be made of a different material. The handle 314 can be removable from the straw 302 or permanently attached to the straw 302. As shown, the body portion 108 of the cap structure 102 has a straw connection port 1302 on the underside of the cap structure 102. The straw connection port 1302 can be positioned opposite to the engagement cavity 308 and defines an insertion hole 1306. The straw connection port 1302 has a vertical guide 1310 (parallel to the length of the straw), which transforms into a horizontal guide 1304 perpendicular to or orthogonal to the vertical guide 1310. Furthermore, as... Figure 14 As shown, the main body of the connection port 1302 is removed, and the straw fitting 1402 within the socket 1306 is configured to fit into the straw opening 814. At the base of the straw fitting 1402 is an elastic washer 812 for sealing the fitting and main body portion 108 of the straw 302.

[0043] like Figures 15 to 16 The diagram illustrates the steps for assembling the straw 302 to the cap structure 102. See also... Figure 15 The tongue 1308 slides upward in the vertical direction 1502 via the vertical guide 1310 of the straw connection portion 1302. To facilitate this process, the straw handle 314 can be directly aligned with the tongue 1308. Once the straw is in the insertion hole 1306, Figure 16 The illustration shows that the straw 302 can rotate clockwise 1602, thereby guiding the tongue 1308 through the horizontal guide 1304, thus locking the straw to the body portion 108. Similarly, this movement can be facilitated by applying a clockwise force to the straw handle 314.

[0044] Furthermore, although some exemplary embodiments of the examples described herein are shown in the accompanying drawings, these embodiments are not intended to be limiting. Rather, it should be understood that the various embodiments and aspects described herein can be implemented on any insulated container.

[0045] Many different arrangements of the various components depicted, as well as those not shown, are possible without departing from the spirit and scope of the invention. Embodiments of the invention have been described, wherein the intention is illustrative rather than limiting. Alternative embodiments will become apparent to those skilled in the art without departing from their scope. Alternative devices implementing the foregoing improvements can be developed by those skilled in the art without departing from the scope of the invention.
