Description

Technical Field

[0001] This utility model specifically relates to a multi-purpose bottle cap kit for storing materials. Background Technology

[0002] Most beverage bottles on the market have caps, allowing consumers to simply unscrew the cap and drink. However, some beverages require additives or other condiments, leading to the development of self-sealing caps. These caps typically have pre-placed additives or other materials inside the cap's cavity. Consumers can then mix the additives with the solution to create their own beverage after opening the cap. These pre-sealed caps are already commercially available as standalone products. Consumers can simply attach the cap to the mouth of a mineral water bottle or other beverage bottle to obtain their mixed drinks, making it more convenient and versatile. This type of cap structure can be referenced in the patent application previously filed by the present invention, number CN202322835761.6, entitled "A Separable Bottle Cap Convenient Unsealing Structure".

[0003] However, existing storage bottle caps are usually designed to a specific size and cannot be used universally on bottles of various diameters. Common mineral water bottles or beverage bottles are based on international standards or industry-standard designs and usually have standard bottle mouth diameters of 24mm, 28mm, and 29mm. After purchasing the aforementioned self-sealing storage bottle cap, it is necessary to purchase a standard beverage bottle with a matching diameter separately. This limits their application range, increases production and inventory costs, and causes great obstacles to use and waste of resources. Therefore, this type of product has extremely poor adaptability and is not conducive to promotion.

[0004] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a multi-purpose bottle cap kit that can store materials. This kit can be adapted to different bottle types and openings by installing accessories, and has stronger versatility and adaptability, and is more convenient to use.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a multi-purpose bottle cap kit for storing materials, including a cap holder and a material cylinder. The cap holder has a mounting sleeve for connecting to the bottle mouth of a bottle. The cap holder and the material cylinder form a storage cavity for storing materials. The cap holder and the material cylinder are movably connected, and a linkage structure for opening the storage cavity is provided between them. The multi-purpose bottle cap kit for storing materials also includes at least one first accessory that can be selectively connected to the mounting sleeve. The inner sidewall of the mounting sleeve has a first internal thread for engaging with the thread of a bottle mouth of one specification. The first accessory has a first connecting cylinder for connecting to a bottle mouth of another specification. The inner sidewall of the first connecting cylinder has a second internal thread for engaging with the thread of the bottle mouth of the other specification.

[0008] The multi-purpose bottle cap kit described above has a detachable connection structure between the first accessory and the mounting sleeve.

[0009] As described above, the multi-purpose bottle cap kit for storing materials also includes a locking structure between the first accessory and the mounting sleeve to prevent the former from coming off when they are connected.

[0010] As described above, the removable connection structure of the multi-purpose bottle cap kit includes a first external thread disposed on the outer wall of the first fitting and mating with the first internal thread.

[0011] As described above, the multi-purpose bottle cap kit for storing materials includes a limiting protrusion on the outer side wall of the first accessory and a limiting groove on the inner side wall of the mounting sleeve.

[0012] As described above, in the multi-purpose bottle cap kit for storing materials, the limiting protrusion is connected to the upper end of the first external thread.

[0013] As described above, the multi-purpose bottle cap kit further includes a first accessory and a second accessory that can be selectively connected to the mounting sleeve. The second accessory has a second connecting cylinder with a different diameter than the first connecting cylinder, and the inner wall of the second connecting cylinder is provided with a third internal thread of a different specification than the second internal thread.

[0014] As described above, the multi-purpose bottle cap kit for storing materials includes a cap holder that is connected to an outer sleeve. When the cap holder is connected to the bottle body, the outer sleeve is located at a position corresponding to the inside of the bottle opening. The material cylinder includes an inner sleeve with an open bottom that can move up and down relative to the outer sleeve. The bottom of the outer sleeve is provided with a capping part that seals the bottom of the inner sleeve when the inner sleeve moves downward. When the inner sleeve moves downward, it and the capping part form the storage cavity. The bottom of the outer sleeve is provided with a discharge port so that the material in the storage cavity can leak out from the discharge port when the inner sleeve moves upward. An outer assembly cylinder is connected above the outer sleeve, and an inner assembly cylinder is connected above the inner sleeve. The linkage structure includes a strip groove that is inclined or partially inclined on the side wall of the inner assembly cylinder. The linkage structure also includes a limiting boss that is provided on the inner side wall of the outer assembly cylinder and extends into the strip groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This utility model provides a multi-purpose bottle cap kit that can accommodate various standard bottle neck sizes. The kit includes a cap holder and a material container, which together form a separately usable cap assembly. The cap assembly itself can accommodate one bottle neck size and can be used independently. The kit also includes at least one accessory, which allows the cap assembly to accommodate another bottle neck size, thus supporting most common 24mm, 28mm, and 29mm standard bottle necks on the market. This greatly improves the product's versatility and adaptability. This multi-functional design not only facilitates user use but also reduces waste caused by mismatched bottle necks, contributing to environmental protection.

[0017] 2. When consumers purchase the storage bottle cap, the storage compartment already contains the materials for blending. Consumers only need to purchase regular mineral water or other beverages to install the storage bottle cap on the beverage bottle. Through the design concept of one bottle cap product meeting multiple needs, not only is the complexity and cost of inventory management reduced, but manufacturing costs are further reduced by reducing the variety of products, thus improving economic efficiency. More importantly, it reduces the number of discarded bottle caps due to mismatched bottle neck specifications, which helps to promote green production and sustainable development.

[0024] The utility model will be further described below with reference to the accompanying drawings:

[0025] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0026] This embodiment describes a multi-purpose bottle cap kit for storing materials, such as... Figures 1 to 5 As shown, this kit includes a bottle cap holder 1 and a material cylinder 2, which are movably connected to form a bottle cap assembly that can be used independently. The material cylinder 2 consists of a cylindrical body 2a that runs vertically through the body and a top cap 2b that seals the top of the cylindrical body 2a. The material cylinder 2 is also a one-piece molded structure, as the lower end of the cylindrical body 2a is open for filling with materials. The bottle cap holder 1 and the material cylinder 2 form a storage cavity 100 for storing materials. The bottle cap holder 1 and the material cylinder 2 are movably connected, and a linkage structure 3 is provided between them to open the storage cavity 100 when the material cylinder 2 rotates. The multi-purpose bottle cap kit also includes at least one first accessory 4 selectively connectable to the mounting sleeve 11. This first accessory 4 is selectively connectable to the bottle cap assembly. The inner wall of the mounting sleeve 11 has a first internal thread 111 for engaging with a bottle neck of one size. The first accessory 4 has a first connecting sleeve 41 for connecting to a bottle neck of another size. The inner wall of the first connecting sleeve 41 has a second internal thread 411 for engaging with the bottle neck of the other size. Specifically, as... Figure 1As shown, the first internal thread 111 on the inner side wall of the mounting sleeve 11 is used for detachable connection with the 24mm diameter standard bottle neck A1. The bottle cap assembly can be directly used with the 24mm diameter standard bottle neck A1 without using the first accessory 4. When the bottle cap assembly needs to be connected to the 28mm diameter standard bottle neck A2, the first accessory 4 is first connected to the bottle cap assembly, and then the bottle cap assembly is connected to the 28mm diameter standard bottle neck A2, so as to adapt to bottle necks of different diameters by using accessories.

[0027] Preferably, this embodiment also includes a second accessory 5, which has the same structure as the first accessory, except that the second connecting cylinder 51 of the second accessory 5 is adaptable to a 29mm diameter standard bottle neck A3, and the inner wall of the second connecting cylinder 51 is provided with a third internal thread 511 that matches the 29mm diameter standard bottle neck A3. To adapt to more bottle necks, accessories for adapting to, for example, 38mm diameter standard bottle necks can also be provided. Therefore, consumers can choose to install different accessories to adapt to most common bottle neck sizes on the market, with a single product meeting multiple needs and reducing the need for users to use different sizes of bottle caps.

[0028] To facilitate the installation and disassembly of accessories, such as Figures 2 to 5 As shown, a detachable connection structure is provided between the first accessory 4 and the mounting sleeve 11. This detachable connection structure includes a first external thread 421 provided on the outer wall of the first accessory 4 and matched with the first internal thread 111, so that the first accessory 4 can be directly installed and connected to the mounting sleeve 11 by tightening the thread.

[0029] As a further optimized implementation method, such as Figure 4 and Figure 6 As shown, a locking structure is provided between the first accessory 4 and the mounting sleeve 11 to prevent the former from dislodging after they are connected. This locking structure includes a limiting protrusion 422 on the outer side wall of the first accessory 4 and a limiting groove 112 on the inner side wall of the mounting sleeve 11. Preferably, the limiting protrusion 422 is connected to the upper end of the first external thread 421. In this way, when the first accessory 4 is screwed onto the mounting sleeve 11, the limiting protrusion 422 engages with the limiting groove 112 to obtain greater damping and prevent the first accessory 4 from loosening and dislodging when the consumer twists the material cylinder 2.

[0030] As a specific implementation of the linkage structure 3, such as Figure 4 and Figure 5As shown, the bottle cap holder 1 also includes an outer sleeve 12 connected to the mounting sleeve 11. When the bottle cap holder 1 is connected to the bottle body, the outer sleeve 12 is located at the position corresponding to the inner side of the bottle opening A. The material cylinder 2 includes an inner sleeve 21 with an open bottom that can move up and down relative to the outer sleeve 12. The bottom of the outer sleeve 12 is provided with a sealing part 121 that seals the bottom of the inner sleeve 21 when it moves downward. When the inner sleeve 21 moves downward, the inner sleeve 21 and the sealing part 121 form the material storage cavity 100. The outer sleeve 12 has a discharge port 122 at its bottom, allowing material in the storage chamber 100 to leak out from the discharge port 122 when the inner sleeve 21 moves upward. An outer assembly cylinder 13 is connected to the top of the outer sleeve 12, and an inner assembly cylinder 22 is connected to the top of the inner sleeve 21. The linkage structure 3 includes a strip groove 221 on the side wall of the inner assembly cylinder 22, which is inclined or partially inclined. The linkage structure 3 also includes a limiting boss 131 on the inner side wall of the outer assembly cylinder 13 that extends into the strip groove 221. When the product is first used, the material cylinder 2 is twisted, causing it to rise relative to the bottle cap seat 1. This releases the lower end of the inner sleeve 21, allowing material to leak out from the discharge port 122 at the bottom of the outer sleeve 12 and enter the bottle. This allows the material to mix with the beverage in the bottle, achieving the function of dispensing, extending the storage time, and providing users with more diverse drinking options. In this embodiment, the material cylinder 2 is composed of a cylindrical body 2a that runs vertically through the cylinder and a top cover 2b that seals the top of the cylindrical body 2a. In the actual production and assembly process, the material cylinder 2 is also an integrally formed structure. Since the lower opening of the cylindrical body 2a can also be used to fill materials, the material cylinder 2 is inverted, and then materials are filled from the bottom of the inner sleeve 21 of the material cylinder 2. The bottle cap seat 1 is also inverted and then connected to the material cylinder 2. Thus, the structure of adding a separate top cover to the material cylinder 2 can be eliminated through the above structure, which greatly simplifies the structure, makes it more compact, makes the sealing performance easier to control, and greatly reduces the production difficulty and production cost.

[0031] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
