Description

Technical Field

[0001] This utility model specifically relates to a bottle cap with a storage cavity. Background Technology

[0002] Most beverage bottles on the market have caps, allowing consumers to simply unscrew the cap and drink. However, some beverages require additional ingredients, leading to the development of filler caps. Filler caps typically have a pre-placed filling inside the cap cavity, allowing consumers to mix the filling with the beverage after opening the cap. The inventor previously developed a detachable cap, comprising a bottom-sealed outer sleeve and a filling cylinder within the outer sleeve. The filling cylinder is connected to the outer sleeve via a movable connection. Initially, the bottom of the filling cylinder rests against the bottom of the outer sleeve. Moving the filling cylinder separates its bottom from the bottom of the outer sleeve, allowing the filling stored in the filling cylinder to flow out and into the beverage in the bottle. For a detailed description, refer to the inventor's previous patent application, CN202322835761.6, entitled "A Convenient Unsealing Structure for a Detachable Bottle Cap." However, traditional filler caps are complex in structure, costly to manufacture, and difficult to produce, resulting in poor product structural stability.

[0003] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bottle cap with a storage cavity that has a simple structure and stronger stability.

[0005] This utility model is achieved through the following technical solution:

[0006] A bottle cap with a storage cavity includes a main cap base, a hopper cap, and a movable component. The main cap base includes a cap portion for connecting to a bottle body, and a storage hopper located at the bottle mouth is connected to the cap portion. The hopper cap is threadedly connected to the top of the storage hopper. The hopper cap and the storage hopper form a storage cavity for storing materials. The movable component is located in the storage cavity and is slidably connected to the hopper cap in the vertical direction, so that when the latter rotates, it drives the former to rotate. A linkage structure is provided between the movable component and the storage hopper, which allows the former to move downward when the former rotates, thereby pressing the storage hopper to break.

[0007] As described above, the bottle cap with a storage cavity has a linkage structure including a threaded groove on the outer wall of the movable part, and an assembly protrusion inserted into the threaded groove is provided on the cylindrical surface of the inner cavity of the storage tank.

[0008] As described above, the bottle cap with a storage cavity has a sharp part at the bottom of the movable part for piercing the bottom of the storage container.

[0009] As described above, the bottle cap with a storage cavity has a tear-resistant portion provided along the bottom edge of the storage container.

[0010] As described above, in the bottle cap with a storage cavity, the tear-resistant portion is a ring-shaped structure, and its center coincides with the rotation center of the movable part. The sharp part is correspondingly positioned above the tear-resistant portion.

[0011] As described above, the bottle cap with a storage cavity has a raised reinforcing part in the middle of the storage tank. The reinforcing part is distributed on the side of the easily tearable part, and the top of the reinforcing part has a guide surface that gradually slopes downward from away from the easily tearable part to near the easily tearable part.

[0012] As described above, in the bottle cap with a storage cavity, the movable part is cylindrical and matches the cylindrical shape of the inner cavity of the storage tank.

[0013] As described above, the bottle cap with a storage cavity has a mounting ring extending into the inside of the movable part. The mounting ring has several sliding grooves arranged in the vertical direction. The inner wall of the movable part has sliding ribs arranged in the vertical direction and inserted into the sliding grooves, so that the movable part rotates when the hopper cap rotates.

[0014] As described above, in the bottle cap with a storage cavity, a sliding rib is provided at the position corresponding to the sharp part.

[0015] As described above, in the bottle cap with a storage cavity, the mounting protrusion is a spiral ridge, the lower part of the movable part is provided with a first blocking part located in the threaded groove and used to block the movement of the mounting protrusion, the upper part of the movable part is provided with a second blocking part located in the threaded groove and used to block the movement of the mounting protrusion, and the second blocking part has a guide surface for the mounting protrusion to pass over the second blocking part when it moves.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Simplified design: By simplifying the design of the bottle cap, the number of processes and materials required in the production process can be reduced, thereby reducing manufacturing costs. The simplified structure may also make assembly easier and improve production line efficiency.

[0018] 2. High efficiency: The moving part is cylindrical with a blade-like sharp part at the bottom. The bottom of the storage tank is also equipped with a tear-resistant part below the sharp part. During the sliding process, the moving part first rests against the tear-resistant part. Then, as the moving part rotates, the blade-like sharp part cuts open the bottom of the storage tank along the tear-resistant part, so that the entire bottom of the storage tank is cut open and separated from the main body. This makes the operation of the bottle cap less resistant and smoother. At the same time, the material in the storage chamber can be released into the bottle quickly, stably and completely.

[0019] 3. Structural stability: In order to improve the strength of the bottom of the storage hopper, the storage hopper is provided with a raised or recessed reinforcing part in the middle. The top of the reinforcing part is provided with a guide surface that gradually slopes downward from away from the tearable part to near the tearable part. In this way, during the rotation of the moving part, the sharp part can be prevented from deviating from the tearable part due to material deformation. The deviated sharp part can be guided to the tearable part, making the structural stability stronger.

[0020] 4. Enhanced User Experience: The addition of a user-friendly opening and closing mechanism improves the consumer experience. Users can easily access the bottle by simply twisting the cap. In addition, the main cap seat and the moving part provide feedback to the user through different resistance levels, allowing the moving part to slide smoothly into place, while also providing the user with clear indications of changes in operating resistance.

[0027] The utility model will be further described below with reference to the accompanying drawings:

[0028] 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.

[0029] This utility model introduces an innovative bottle cap design, such as... Figures 1 to 4 As shown, this bottle cap integrates a storage cavity and mainly consists of a main cap base 1, a hopper cover 2, and a movable component 3. The main cap base 1 has a cap portion 11 for connecting to the bottle body A, on which a storage hopper 12 located at the bottle mouth A1 is installed. In practical applications, the cap portion 11 is securely screwed onto the bottle mouth A1 via a threaded structure, while the storage hopper 12 is placed inside the bottle mouth A1 or extends into the bottle body A. The hopper cover 2 is threadedly connected to the top of the storage hopper 12. The hopper cover 2 and the storage hopper 12 form a storage cavity 10 for storing materials. The movable component 3 is located in the storage cavity 10. The movable component 3 is slidably connected to the hopper cover 2 in the vertical direction, so that when the latter rotates, it drives the former to rotate. A linkage structure B is provided between the movable component 3 and the storage hopper 12, which allows the former to move downward when the former rotates, thereby pressing the storage hopper 12 to break. In this embodiment, the material stored in the storage chamber 10 is tea powder, but it can also store seasonings, sugar powder, honey, etc. The bottom of the storage bucket 12 is made of thin-walled material or partially made of thin-walled material. When in use, the user unscrews the hopper cover 2. When the hopper cover 2 rotates, it drives the movable part 3 to rotate. When the movable part 3 rotates, it slides downward and pierces or punches the bottom of the storage bucket 12, thereby releasing the material in the storage chamber 10 into the bottle A and mixing with the liquid in the bottle.

[0030] As a preferred implementation method, such as Figures 2 to 5 As shown, the movable part 3 is cylindrical and matches the cylindrical shape of the inner cavity of the storage bucket 12, so that the movable part 3 fits into the inner cavity of the storage bucket 12, the structure is stable, and the movable part 3 can rotate and slide smoothly up and down in the inner cavity of the storage bucket 12.

[0031] As a preferred implementation of the linkage structure B, such as Figure 2 and Figure 3As shown, the linkage structure B includes a threaded groove 31 on the outer wall of the movable part 3. The inner cylindrical surface of the storage tank 12 is provided with an assembly protrusion 121 that inserts into the threaded groove 31. In this embodiment, the hopper cover 2 and the storage tank 12 are connected by a right-hand thread, while the linkage structure B is connected by a left-hand thread, so that when the hopper cover 2 is loosened upwards, the movable part 3 moves downwards. Of course, the hopper cover 2 and the storage tank 12 can also be connected by a left-hand thread, while the linkage structure B is connected by a right-hand thread. Of course, the hopper cover 2 and the storage tank 12, as well as the linkage structure B, can both be connected by a left-hand thread or a right-hand thread. The key is whether the threaded groove 31 is located on the inner or outer side of the movable part 3.

[0032] As a priority, such as Figures 2 to 4 As shown, the bottom of the movable part 3 is provided with a sharp part 33 for piercing the bottom of the storage bucket 12, so that the movable part 3 can smoothly and quickly pierce the bottom of the storage bucket 12 when it moves downward.

[0033] As a further preferred implementation, such as Figure 2 and Figure 3 As shown, the storage bin 12 has a tear-resistant portion 122 along its bottom edge, and the tear-resistant portion 122 is a thin-walled material with a reduced thickness at the bottom of the storage bin 12. As a further optimization, the sharp part 33 is blade-shaped, and the tear-resistant portion 122 is a ring-shaped structure, that is, the tear-resistant portion 122 is a ring-shaped structure between the bottom wall and the side wall of the storage bin 12, and its center coincides with the rotation center of the movable part 3. The sharp part 33 is correspondingly positioned above the tear-resistant portion 122, such as... Figure 6 As shown, this causes the movable part 3 to first abut against the easily tearable part 122 during the sliding process, and then the blade-shaped sharp part 33 cuts open the bottom of the storage bucket 12 along the easily tearable part 122 during the rotation of the movable part 3, so that the entire bottom of the storage bucket 12 is cut open and separated from the body.

[0034] As a preferred option, such as Figure 2 and Figure 3 As shown, to improve the strength of the bottom of the storage bin 12, a raised or recessed reinforcing part 123 is provided in the middle of the storage bin 12. At least two reinforcing parts 123 are distributed along the circumference, making the middle structure of the storage bin 12 stronger and less prone to deformation. Therefore, when the movable part 3 moves downwards, the middle of the storage bin 12 will not easily deform, making the easily tearable part 122 easier to puncture and tear. As a further optimization, such as... Figure 6As shown, the reinforcing part 123 is distributed on one side of the easily tearable part 122, and the top of the reinforcing part 123 is provided with a guide surface 124 that gradually slopes downward from away from the easily tearable part 122 to near the easily tearable part 122. In this way, during the rotation of the movable part 3, the sharp part 33 can be prevented from deviating from the easily tearable part 122 due to material deformation, and the deviated sharp part 33 can be guided to the easily tearable part 122, so as to make the structure more stable.

[0035] To ensure that the rotation of the hopper cover 2 drives the rotation of the movable part 3 without affecting the vertical sliding of the movable part 3 relative to the hopper cover 2, such as... Figure 2 and Figure 3 As shown, the hopper cover 2 is provided with an installation ring 21 that extends into the inner side of the movable part 3. The installation ring 21 is provided with a plurality of sliding groove holes 211 arranged in the vertical direction. The inner side wall of the movable part 3 is provided with sliding ribs 32 arranged in the vertical direction and inserted into the sliding groove holes 211, so that the movable part 3 is driven to rotate when the hopper cover 2 rotates.

[0036] To improve the strength of the structure, one of the sliding ribs 32 is provided at the position corresponding to the sharp part 33.

[0037] As a preferred option, such as Figure 2 and Figure 3 As shown, the mounting protrusion 121 is a spiral-shaped ridge, that is, the mounting protrusion 121 is not a complete spiral strip, but a small segment of spiral ridge. As a further preferred embodiment, such as... Figure 5 As shown, the lower part of the movable part 3 is provided with a first blocking part 34 located in the threaded groove 31 to block the movement of the assembly protrusion 121. The upper part of the movable part 3 is provided with a second blocking part 35 located in the threaded groove 31 to block the movement of the assembly protrusion 121. The second blocking part 35 has a guide surface 351 for the assembly protrusion 121 to pass over the second blocking part 35 when it moves. In this way, when the movable part 3 rotates, it is blocked by the first blocking part 34 and cannot move upward. After the movable part 3 rotates and moves upward, it is blocked by the second blocking part 35, which increases the resistance to turning the hopper cover 2. After continuing to turn the hopper cover 2, the assembly protrusion 121 can pass over the second blocking part 35 through the guide surface 351, thereby allowing the movable part 3 to slide down into place. The different resistances provide the user with feedback of damping, so that the movable part 3 can slide down into place smoothly, while giving the user a clear indication of the change in operating resistance. In addition, due to the above structure, the movable part 3 is cylindrical, so there is no need to position the movable part 3 during assembly. The movable part 3 can simply be placed into the main cover seat 1, making assembly more convenient.

[0038] 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.
