Description

Technical Field

[0001] The present invention specifically relates to a self-sealing storage cap assembly compatible with multiple bottle types. Background Art

[0002] Most beverage bottles on the market are equipped with bottle caps. Consumers can open the bottle caps and drink after purchasing beverages. However, some beverages require additives such as seasonings, so self-sealing storage caps have emerged. Self-sealing storage caps usually pre-place seasonings and other materials in the inner cavity of the bottle caps. After consumers open the bottle caps, they can mix the seasonings with the solution to make beverages by themselves. Moreover, bottle caps storing such materials have been made into independent products on the market. After consumers purchase such products, they only need to connect the bottle caps to the mouths of mineral water bottles or other beverage bottles to obtain mixed beverages, which is more convenient to use and has a wider range of applications. The structure of such bottle caps can refer to the patent solution of the present inventor's previously applied patent with the patent number CN202322835761.6 and the title of a separable bottle cap convenient unsealing structure.

[0003] However, existing storage caps are usually designed with specific sizes and cannot be used universally on bottles of various calibers. Common mineral water bottles or beverage bottles are based on international standards or industry general designs, usually having standard bottle mouths with calibers of 28mm and 38mm. After purchasing the above-mentioned self-sealing storage cap products, it is necessary to additionally purchase standard beverage bottles that can match the caliber, which limits their application scope, increases production and inventory costs, causes great obstacles to use and waste of resources. Therefore, such products have extremely poor adaptability and are not conducive to promotion.

[0033] Embodiment 1

[0034] This embodiment introduces a multi-bottle-type compatible self-sealing storage cover assembly. This storage bottle cap includes a cover base 1 and a material cylinder 2. The material cylinder 2 is composed of a cylinder body 2a that penetrates up and down and a top cover 2b that seals the top of the cylinder body 2a. Of course, the material cylinder 2 is also an integrally formed integral structure, and materials can be filled through the lower opening of the cylinder body 2a. As Figure 1 shown, in this embodiment, this storage cover assembly is mainly applied to the 28mm diameter standard bottle mouth A2 and the 38mm diameter standard bottle mouth A1. Of course, in order to adapt to a small number of 24mm diameter bottle mouths or 29mm diameter bottle mouths, the dimensions can also be appropriately adjusted. Specifically, as Figures 2 to 4As shown in the figure, it includes a cover base 1 and a barrel 2. A storage cavity 100 for storing materials is formed between the cover base 1 and the barrel 2. The cover base 1 and the barrel 2 are movably connected, and a linkage structure 3 is provided between them to open the storage cavity 100 when the barrel 2 rotates. The cover base 1 includes an installation sleeve 11 for connecting to the bottle mouth A of the bottle body. The installation sleeve 11 has at least a first screw connection cylinder section 111 and a second screw connection cylinder section 112 for screw connection with bottle mouths of different specifications. Inner threads for connecting with the external threads of the bottle mouth A are provided on the inner sides of both. In this embodiment, the second screw connection cylinder section 112 is located below the first screw connection cylinder section 111, and the caliber of the second screw connection cylinder section 112 is larger than that of the first screw connection cylinder section 111. Among them, the first screw connection cylinder section 111 is designed to match the thread structure of a standard bottle mouth with a caliber of 28 mm, and the second screw connection cylinder section 112 is designed to match the thread structure of a standard bottle mouth with a caliber of 38 mm. In this way, the cap assembly can be installed and connected to mineral water bottles or beverage bottles of two different size specifications. This makes the cap assembly have stronger adaptability, can easily adapt to most common bottle mouth sizes in the market, reduces the user's need for bottle caps of different specifications; a single product meets multiple needs, reduces inventory costs and complexity; by reducing the types of production, reduces manufacturing costs and improves economic benefits; reduces the number of discarded bottle caps caused by incompatibility, which helps environmental protection.

[0035] Specifically, as Figures 2 to 4As shown, the cap base 1 further includes an outer sleeve 12 connected to the mounting sleeve 11. When the cap base 1 is connected to the bottle body, the outer sleeve 12 is located at the corresponding position inside the bottle mouth A. The cartridge 2 includes an inner sleeve 21 with an open bottom and capable of moving up and down relative to the outer sleeve 12. The bottom of the outer sleeve 12 is provided with a capping portion 121 for capping the bottom of the inner sleeve 21 after the inner sleeve 21 moves downward. After the inner sleeve 21 moves downward, the inner sleeve 21 and the capping structure enclose the storage cavity 100. The bottom of the outer sleeve 12 is provided with a discharge port 122 so that the material in the storage cavity 100 can leak out from the discharge port 122 when the inner sleeve 21 moves upward. An outer assembly cylinder 13 is connected above the outer sleeve 12, and an inner assembly cylinder 22 is connected above the inner sleeve 21. The linkage structure 3 includes a strip-shaped groove 221 provided on the side wall of the inner assembly cylinder 22 and inclined or partially inclined, and the linkage structure 3 further includes a limiting boss 131 provided on the inner side wall of the outer assembly cylinder 13 and extending into the strip-shaped groove 221. When starting to use the product, the cartridge 2 is screwed to make the cartridge 2 rise relative to the cap base 1, and then the lower end of the inner sleeve 21 is unsealed. The material leaks out from the discharge port 122 at the bottom of the outer sleeve 12 and then enters the bottle, so that the material is mixed with the drink in the bottle, thus realizing the function of sub-packaging, prolonging the storage time and providing more diversified drinking options for users. In this embodiment, the cartridge 2 is composed of a cylinder 2a with a through hole up and down and a top cover 2b for capping the top of the cylinder 2a. In the actual production and assembly process, the cartridge 2 is also an integrally formed overall structure. Since the lower end of the cylinder 2a is open, the material can also be filled. The cartridge 2 is turned upside down, and then the material B is filled from the bottom of the inner sleeve 21 of the cartridge 2. The cap base 1 is also turned upside down and then covered and connected with the cartridge 2. Then, through the above structure, the structure of additionally covering the top of the cartridge 2 can be cancelled, greatly simplifying the structure, making it more compact, easier to control the sealing performance, and at the same time greatly reducing the production difficulty and production cost.

[0036] Preferably, as Figure 2 and Figure 4 shown, a guiding groove 222 for the limiting boss 131 to slide into the strip-shaped groove 221 is further provided on the side wall of the inner assembly cylinder 22. The lower end of the guiding groove 222 is open, so that the outer ring cylinder can be covered on the top of the outer sleeve 12 from top to bottom. The guiding groove 222 is provided with an inclined first guiding slope 223 on the side close to the strip-shaped groove 221. The top of the limiting boss 131 is provided with a second guiding slope 132 that is inclined and reversely matched with the strip-shaped groove 221. In this way, when the cartridge 2 and the cap base 1 are installed and connected, the limiting boss 131 slides along the guiding groove 222 and slides into the strip-shaped groove 221 through the first guiding slope 223, and the installation is more convenient. The second guiding slope 132 can make the limiting boss 131 slide more smoothly in the strip-shaped groove 221.

[0037] Example Two

[0038] This example introduces a multi-bottle-compatible self-sealing storage cap assembly. As Figure 5 shown, the difference between this example and Example One is that on the installation sleeve 11, there is also a flared section 113 located below the second threaded barrel section 112 and with a larger diameter than the second threaded barrel section 112. This makes the connection matching degree between the product and the beverage bottle higher. Through the flared section 113, some connection structures can be shielded, improving the visual appearance.

[0039] Example Three

[0040] This example introduces a multi-bottle-compatible self-sealing storage cap assembly. As Figure 6 and Figure 7 shown, the difference between this example and Example One is that on the installation sleeve 11, there is a tearing structure located between the first threaded barrel section 111 and the second threaded barrel section 112 and used to separate the second threaded barrel section 112.

[0041] Specifically, as Figure 6 and Figure 7 shown, the tearing structure includes a tearing ring 114 arranged circumferentially. Between the tearing ring 114 and the first threaded barrel section 111, and between the tearing ring 114 and the second threaded barrel section 112, they are all connected by thin walls. And on the tearing ring 114, a handle part 116 for people to hold can be set. By tearing the tearing ring 114, the second threaded barrel section 112 can be separated from the installation sleeve 11. This is more convenient to use on small-diameter bottle bodies and can avoid interference with the bottle body shape or structure.

[0042] Example Four

[0043] This example introduces a multi-bottle-compatible self-sealing storage cap assembly. As Figure 6 and Figure 9 shown, the installation sleeve 11 also has a third threaded barrel section 115 located below the second threaded barrel section 112 and used to connect with the bottle mouth. The diameter of the third threaded barrel section 115 is larger than that of the second threaded barrel section 112. This enables the cap assembly to adapt to three or more bottle body specifications, such as the less common 24mm-diameter bottle mouth or 29mm-diameter bottle mouth described in Example One. For example, the first threaded barrel section 111 is adapted to the 24mm-diameter bottle mouth, the second threaded barrel section 112 is adapted to the 29mm-diameter bottle mouth, and the third threaded barrel section 115 is adapted to the 28mm-diameter bottle mouth. It can also be other combination methods.

[0044] The above are only embodiments of the present invention, and common general knowledge such as specific structures and characteristics known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
