Abstract
Description
Technical Field
[0001] This invention relates to the field of beverage bottle technology, and more particularly to a storage-type beverage bottle cap and a beverage bottle. Background Technology
[0002] Beverages, as a popular beverage in modern society, have seen widespread development. Conventional beverages are processed in factories and then bottled, with the bottle serving as a sealed storage medium. During storage, some ingredients in the beverage may settle or precipitate. Later, ready-to-drink beverages were designed, which separate the liquid from the flavoring agents. A separate storage space is provided inside the bottle cap for the flavoring agents; before drinking, the flavoring agents are mixed with the liquid. Currently, most beverages use a twist-to-open seal mechanism.
[0003] For example, patent application number CN2023216397792 discloses a screw-on beverage bottle cap; including a cylinder, a bottle cap, and a rotating cylinder. Utilizing the rotating action of the bottle cap, it employs a ratchet-like structure where the limiting block on the rotating cylinder and the groove on the inner wall of the solvent chamber of the cylinder can only rotate in one direction. Furthermore, the pitch of the rotating cylinder thread on the outer wall of the upper end of the rotating cylinder and the inner bottle cap thread on the inner wall of the inner bottle cap are greater than the pitch of the thread on the outer edge of the upper end of the cylinder and the inner thread on the inner wall of the bottle cap. This solves the problem of the original method of using forward and reverse threads for screwing, where the rotating cylinder cannot be directly lowered vertically, resulting in the pointed end of the rotating cylinder puncturing the protrusion at the bottom of the cylinder instead of puncturing it, thus increasing the difficulty of opening the bottle.
[0004] In actual use, damaged seals can easily fall into or partially detach and enter the liquid; moreover, the sealing structure can be damaged by differential speed or other operations, which can affect the overall sealing performance; and, in the case of liquid separation, the cost of the bottle cap increases, but it is still for single use, resulting in a certain waste of resources.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0055] Reference Figure 1-25 A storage-type beverage bottle cap and beverage bottle, comprising: an internally threaded cylindrical section 1 that mates with the bottle mouth, and an internally threaded cylindrical section 1 having an integrally disposed storage bin 2 with a central channel on its upper part.
[0056] That is, an integral storage bin 2 is formed above the bottle mouth assembly structure (internal thread cylindrical section 1); the storage bin 2 can store materials such as tea powder, beverage powder and concentrated liquid according to design requirements; wherein, the outer diameter of the storage bin 2 is the same as that of the internal thread cylindrical section 1, and it is provided with anti-slip texture, and the whole is cylindrical in shape.
[0057] Correspondingly, a channel plate 3 is integrally installed at the lower end of the storage bin 2, and a closed or connected structure is formed by a blocking plate 4.
[0058] When not in use, the blocking plate 4 cooperates with the channel plate 3 to seal the lower end of the storage bin 2, and the material is stored in the storage bin 2. Before drinking, the blocking plate 4 is pressed down to separate it from the channel plate 3, connecting the storage bin 2 with the space inside the bottle. At this time, the bottle can be shaken to let the material fall, or it can be inverted to allow the liquid inside the bottle to enter the storage bin 2 for mixing.
[0059] Unlike conventional methods that use rotation and downward pressure to break the seal, in this design, the blocking plate 4 is driven by the pressing column 5 extending upward from the central channel; that is, by applying external force to the pressing column 5 from the top, the blocking plate 4 can be driven to form a closed or connected adjustment.
[0060] In some embodiments, the channel plate 3 includes an outer ring body 31, a central ring 32, and a plurality of connecting arms 33 connecting the outer ring body 31 and the central ring 32; a hybrid channel is formed between the connecting arms 33, and a blocking plate 4 is located at the lower end of the channel plate 3.
[0061] As shown in the attached diagram; the space above the channel plate 3 is the storage bin 2, and the space below is the internally threaded cylindrical section 1; the outer ring 31 is integrally connected to the inner wall, and the upper edge junction (the inner bottom edge of the storage space) is set with an arc corner to reduce residue, adhesion, etc., and facilitate subsequent cleaning operations; the central ring 32 is sealed to the pressing column 5; multiple connecting arms 33 arranged around it stabilize the central ring 32 and form a mixing channel; after the blocking plate 4 moves away, the lower end of the mixing channel is connected to the space inside the bottle.
[0062] Furthermore, the lower end of the channel plate 3 is provided with a stepped annular groove 34 of no less than two levels.
[0063] Correspondingly, the outer ring of the plug plate 4 is a stepped surface 41 that matches it, forming a more reliable and effective seal.
[0064] Furthermore, the corner of the stepped annular groove 34 is set to be arc-shaped, which has a better sealing effect and better cleanliness.
[0065] In some embodiments, the central axis of the storage bin 2 is formed by a central channel through a lower connecting channel plate 3 and an upper internally open inner core cylinder 6.
[0066] like Figure 9 As shown, the outer side of the top of the inner core cylinder 6 extends outward and is integrated with the top surface of the storage bin 2; the outer side of the inner core cylinder 6 cooperates with the inner wall of the storage bin 2 to form a storage space.
[0067] Correspondingly, the pressing column 5 is set inside the inner core cylinder 6 and moves vertically to drive and adjust the blocking plate 4.
[0068] The inner core 6 forms a channel located at the central axis of the storage bin 2, but independent of the storage space, connecting the outside and the bottle space; in conjunction with the central ring 32 and the pressing column 5 in a sealed configuration, it drives the blocking plate 4.
[0069] In some embodiments, the outer diameter of the pressing column 5 is sealed to the center hole of the channel plate 3 and is smaller than the inner diameter of the inner core cylinder 6; at the same time, a spring is sleeved on the outside of the pressing column 5, and a pressing section 51 pressed by the spring is provided on the top.
[0070] It is understandable that the lower end of the pressing section 51 contacts the spring, and its outer diameter is larger than that of the pressing post 5; preferably, the outer diameter of the pressing section 51 matches the inner diameter of the inner core cylinder 6.
[0071] like Figure 11As shown; without external force applied, the spring pushes the pressing section 51 upward, causing the blocking plate 4 to press tightly against the channel plate 3, forming a closed shape; after external force is applied and the spring is resisted, the spring is compressed, and the blocking plate 4 moves downward away from the channel plate 3.
[0072] It should be noted that, in order to avoid accidental pressing of the pressing column 5 during transportation and storage, the top of the pressing column 5 is recessed into the inner core cylinder 6.
[0073] Furthermore, the inner core cylinder 6 is fitted with a pressing column 5 and is equipped with a thick sealing ring 61 that is pressed down by a spring.
[0074] like Figure 9 , 11 As shown in Figures 1 and 14, the sealing effect is further enhanced during movement.
[0075] Preferably, the thick sealing ring 61 has a hollow structure; its inner diameter is compressed when subjected to downward pressure.
[0076] like Figure 13 As shown; preferably, an annular space is formed inside the thick sealing ring 61; and the inner ring sidewall (the side with the smaller radius) corresponding to the annular space is thinner; when no external force is applied, gas is rushed into the annular space, causing the inner ring to expand inward; after being compressed, the thinner inner ring sidewall is more easily deformed, and the deformation on the inner ring side increases, further enhancing the compression sealing effect.
[0077] In some embodiments, the lower end of the pressing section 51 is threadedly and detachably connected to the top end of the pressing post 5.
[0078] like Figure 14 As shown; after the pressing section 51 is pressed down, it drives the blocking plate 4 away from the storage bin 2, opening the lower end.
[0079] Furthermore, when the blocking plate 4 is away from the storage bin 2, the blocking plate 4 can be removed along with the pressing column 5.
[0080] In other words, when the pressing section 51 is pressed down, the blocking plate 4 protrudes outward and can be rotated to separate the pressing section 51 from the pressing column 5; the pressing column 5 and the blocking plate 4, which are fixedly connected together, can be removed.
[0081] In this invention, by setting the blocking plate 4, the storage bin 2 is no longer a disposable form and can be reused multiple times; moreover, the blocking plate 4 is detachable, which not only makes it easy to add materials into the storage bin 2, but also facilitates internal cleaning, maintenance and other operations.
[0082] In some embodiments, a sealing sticker 62 is affixed to the top of the inner core cylinder 6 and the top surface of the storage bin 2.
[0083] It should be noted that, in order to prevent dirt from entering the recessed space at the top of the inner core 6, and to ensure that the beverage has not been opened when the user receives it, a sealing sticker 62 is designed as a protective and anti-counterfeiting measure.
[0084] like Figure 8 As shown; before drinking, the sealing sticker 62 covers the top, not exposing the pressing post 5; the undamaged sealing sticker 62 also forms a certain anti-counterfeiting function; before drinking, peel off the sealing sticker 62 to expose the pressing post 5.
[0085] It is understandable that a prompt would be placed on the sealing sticker 62 or on the top of the bottle cap.
[0086] In some embodiments, a waterproof sticker 7 is provided on the lower end face of the blocking plate 4 in conjunction with the channel plate 3 of the storage bin 2; the waterproof sticker 7 is provided with a sealing tear line corresponding to the edge of the blocking plate 4.
[0087] like Figures 16-18 As shown; when the blocking plate 4 is pressed down, the sealing tear line is easily torn open; the outer ring of the waterproof sticker 7 remains on the channel plate 3, while the inner ring is taken away by the blocking plate 4.
[0088] It is important to note that waterproof stickers should be used with care to ensure hygiene and safety, and should not contaminate the liquid inside the bottle.
[0089] In this configuration, the waterproof sticker 7 serves as a further anti-counterfeiting measure; the cap can be removed for inspection before consumption.
[0090] Furthermore, the waterproof sticker 7 has a production date set on it; setting the production date as a built-in feature makes it more credible and reliable.
[0091] Understandably, the lower end of the internally threaded cylindrical section 1 is also equipped with a commonly used anti-theft ring for bottle caps to prevent the bottle cap from being removed directly.
[0092] Furthermore, to avoid the influence of adhesive at the tear location: the waterproof sticker 7 forms a certain width of annular adhesive-free area at the sealing tear line; in the torn state, no adhesive influence is formed.
[0093] In some embodiments, the lower end of the storage bin 2 is provided with a groove 21 corresponding to the bottle mouth structure, and a sealing gasket ring 22 is provided in the groove 21 to enhance the sealing of the bottle body space.
[0094] Furthermore, the top of the slot 21 is provided with multiple upward through-holes 211; the top of the sealing ring 22 is integrally provided with multiple protruding blocks 221.
[0095] like Figure 11 , 19As shown in Figure 20, the installation of the sealing gasket 22 is more secure and not easy to fall off or move. In addition, after the sealing gasket 22 is removed, materials can be added or cleaned through the connecting port 211 (which is a relatively small port).
[0096] In some embodiments, it further includes: an inverted cap 8 that covers the bottle cap.
[0097] The inverted cover 8 is flared in shape, with a smaller top and a larger bottom, and is fitted onto the outside of the storage bin 2.
[0098] The inverted cover 8 forms a protective layer, further preventing contamination and damage to the sealing sticker 62.
[0099] In some embodiments, the top of the inverted cover 8 is provided with an open central opening; the pressing post 5 can be pressed through the central opening.
[0100] like Figure 7 As shown, mixing can be performed without removing the inverted shell cover 8.
[0101] It should be noted that in the aforementioned embodiments, the top of the inverted cover 8 can be formed into a closed shape to form complete protection.
[0102] In this embodiment, if a central opening is provided, a removable plug or other structure can be installed inside the central opening.
[0103] In some embodiments, the top of the inverted cap 8 is recessed and provided with a U-shaped groove 81 that mates with the bottle mouth structure.
[0104] The inner side of the U-shaped groove 81 is an open central top opening for operating the pressing column 5; and for placing plugs and other structures.
[0105] In the inverted state, the U-shaped groove 81 is engaged with the inner and outer sides of the bottle mouth, causing the inverted cap 8 to form a funnel shape.
[0106] like Figures 21-24 As shown, it can assist in adding liquid into the bottle, allowing the inverted cap 8 to be used more effectively.
[0107] In some embodiments, a filter plate 9 is fitted inside the central top opening on the inner side of the U-shaped groove 81.
[0108] In normal operation, filter plate 9 forms a blockage; before operating the pressing column 5, filter plate 9 needs to be removed; when in funnel form, it forms a sieving effect; for example, adding tea water into the bottle.
[0109] Preferred, such as Figure 25 As shown; the outer ring of the filter plate 9 is integrally provided with a retaining ring 91, and the top of the filter plate 9 is integrally provided with a handle body 92; the placement is more stable and the operation is easier.
[0110] A beverage bottle having the aforementioned storage-type beverage bottle cap.
[0111] Before drinking, you can choose to open the bottle cap to check the waterproof sticker 7 inside; with the bottle cap tightened in place, remove the inverted cap 8, tear off the sealing sticker 62, and press down on the pressing section 51 to open the lower end of the storage compartment 2; then, mix the material in the storage compartment 2 with the liquid in the bottle. It can be reused; open the storage compartment 2 and add material inside; under the pushing state of the spring, the blocking plate 4 closes the channel plate 3.
[0112] In this invention, a storage space that can be connected and closed multiple times is formed, and the closed structure is controllable and effective, enabling multiple uses; a multi-level anti-counterfeiting system further ensures the effectiveness and reliability of food information; and the designed inverted cap 8 strengthens the protection of the bottle cap, while also forming a funnel shape to assist in adding to the interior.
