Description

Technical Field

[0001] The present invention particularly relates to a bottle cap with a storage cavity. Background Art

[0002] Most of the beverage bottles on the market are equipped with bottle caps. Consumers can drink by unscrewing the bottle caps after purchasing the beverages. However, some beverages require auxiliary materials such as adjustment, so storage-type bottle caps have appeared. Storage-type bottle caps usually place adjustment in advance in the internal cavity of the bottle cap. After opening the bottle cap, consumers can blend the adjustment with the solution into a beverage. The inventor has previously developed a detachable bottle cap, which includes an outer sleeve with a closed bottom and a storage barrel arranged in the outer sleeve. The storage barrel is connected to the outer sleeve by a movable connection. In the initial state, the bottom end of the storage barrel is against the bottom of the outer sleeve. By moving the storage barrel, its bottom end is separated from the bottom of the outer sleeve, so that the auxiliary materials stored in the storage barrel flow out and flow into the beverage in the beverage bottle. The specific structure can refer to the inventor's previous patent application number CN202322835761.6, named a patent scheme for a convenient unsealing structure of a detachable bottle cap. However, the traditional storage-type bottle cap has a complex structure, high manufacturing cost, and high production difficulty, resulting in poor product structural stability.

[0007] In the bottle cap with storage cavity as described above, the linkage structure comprises a threaded groove arranged on the outer side wall of the movable part, and an assembly protrusion inserted into the threaded groove is arranged on the inner cylindrical surface of the storage barrel.

[0008] As described above, in the bottle cap with a storage cavity, the bottom of the movable part is provided with a sharp portion for piercing the bottom of the storage barrel.

[0009] In the bottle cap with a storage cavity as described above, the storage barrel is provided with an easy-to-tear portion along the edge of the bottom surface thereof.

[0011] As described above, in the bottle cap with a storage cavity, a raised reinforcement portion is provided in the middle of the storage barrel, the reinforcement portion is distributed on one side of the easy-to-tear portion, and a guide surface is provided on the top of the reinforcement portion which gradually inclines downward from the direction away from the easy-to-tear portion to the direction close to the easy-to-tear portion.

[0012] In the bottle cap with storage cavity as described above, the movable part is cylindrical and matches the cylindrical shape of the inner cavity of the storage barrel.

[0013] As described above, in the bottle cap with a storage cavity, the silo cover is provided with a mounting ring extending into the inner side of the movable part, the mounting ring is provided with a plurality of sliding slots arranged along the up-down direction, and the inner side wall of the movable part is provided with sliding ribs arranged along the up-down direction and inserted into the sliding slots, so that the movable part is driven to rotate when the silo cover rotates.

[0014] In the bottle cap with a storage cavity as described above, a sliding rib is arranged at a position corresponding to the sharp portion.

[0015] In the bottle cap with a storage cavity as described above, the assembly protrusion is a spiral protrusion, the lower part of the movable part is provided with a first blocking portion located in the thread groove and used to block the movement of the assembly protrusion, the upper part of the movable part is provided with a second blocking portion located in the thread groove and used to block the movement of the assembly protrusion, and the second blocking portion has a guide surface for the assembly protrusion to pass over the second blocking portion when moving.

[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 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 movable part is cylindrical and has a blade-like sharp part at the bottom, and a circle of easy-to-tear part is correspondingly arranged below the sharp part at the bottom of the storage barrel. During the sliding process, it first leans against the easy-to-tear part, and then during the rotation of the movable part, the blade-like sharp part cuts the bottom of the storage barrel along the easy-to-tear part, so that the entire bottom of the storage barrel is cut and separated from the body, so that the resistance of the entire bottle cap is smaller during operation, and the operation is smoother. At the same time, the material in the storage cavity can be quickly, stably and completely released into the bottle body.

[0019] 3. Structural stability: In order to improve the strength of the bottom of the storage barrel, a convex or concave reinforcement portion is provided in the middle of the storage barrel, and a guide surface is provided on the top of the reinforcement portion, which gradually tilts downward from the direction away from the easy-to-tear portion to the direction close to the easy-to-tear portion. In this way, during the rotation of the movable part, the situation where the sharp portion deviates from the easy-to-tear portion due to material deformation can be avoided, and the deviated sharp portion can be guided to the easy-to-tear portion, making the structural stability stronger.

[0020] 4. Improved user experience: Adding a user-friendly opening and closing mechanism can improve the consumer experience. The user only needs to twist the bottle cap normally to allow the material in the bottle cap to enter the bottle body, which is convenient to use. In addition, the main cap seat and the movable part give the user damping feedback through different resistances, so that the movable part can slide smoothly into place, and at the same time give the user a clear reminder of the change in operating resistance.

[0027] The invention will be further described below in conjunction with the accompanying drawings:

[0028] The directions described in the specification of the present invention, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the invention and are not a limitation on its implementation method.

[0029] The present invention introduces an innovative bottle cap design, such as Figures 1 to 4As shown, this bottle cap integrates a storage cavity, and is mainly composed of a main cap seat 1, a silo cover 2 and a movable part 3. The main cap seat 1 has a bottle cap portion 11 for connecting with the bottle body A, and a storage barrel 12 located at the bottle mouth A1 is installed on this portion. In practical applications, the bottle cap portion 11 is firmly screwed on the bottle mouth A1 through a threaded structure, and the storage barrel 12 is placed inside the bottle mouth A1 or deep into the bottle body A. The silo cover 2 is connected to the top of the storage barrel 12 through a threaded structure, and the silo cover 2 and the storage barrel 12 form a storage cavity 10 for storing materials. The movable part 3 is located in the storage cavity 10, and the movable part 3 is slidably connected with the silo cover 2 in the up and down direction so that the latter drives the former to rotate when the latter rotates. A linkage structure B is provided between the movable part 3 and the storage barrel 12, which can make the former move downward when the former rotates, thereby pressing the storage barrel 12 to break. In the present embodiment, the material stored in the storage chamber 10 is tea powder, and of course, seasonings, powdered sugar, honey, etc. can also be stored, and the bottom of the storage barrel 12 is made of thin-walled material or partially made of thin-walled material. When in use, the user unscrews the silo cover 2, and when the silo cover 2 rotates, it drives the movable part 3 to rotate. When the movable part 3 rotates, it slides downward and then pushes or pierces the bottom of the storage barrel 12, so that the material in the storage chamber 10 is released into the bottle body A and mixed with the liquid in the bottle.

[0030] As a preferred embodiment, Figures 2 to 5 As shown, the movable part 3 is cylindrical and matches the cylindrical shape of the inner cavity of the material storage barrel 12, so that the movable part 3 is sleeved in the inner cavity of the material storage barrel 12, the structure is stable, and the movable part 3 can smoothly rotate and slide up and down in the inner cavity of the material storage barrel 12.

[0031] As a preferred implementation of the linkage structure B, Figure 2 and Figure 3 As shown, the linkage structure B includes a thread groove 31 arranged on the outer wall of the movable part 3, and an assembly protrusion 121 inserted into the thread groove 31 is provided on the inner cylindrical surface of the storage barrel 12. In this embodiment, a right-handed thread is used between the silo cover 2 and the storage barrel 12, and the linkage structure B adopts a left-handed thread, so that when the silo cover 2 is loosened upward, the movable part 3 moves downward. Of course, a left-handed thread can also be used between the silo cover 2 and the storage barrel 12, and the linkage structure B adopts a right-handed thread. Of course, the silo cover 2 and the storage barrel 12 and the linkage structure B both adopt left-handed threads or right-handed threads. The key lies in whether the thread groove 31 is arranged on the inner side or the outer side of the movable part 3.

[0032] As a priority, Figures 2 to 4 As shown, the bottom of the movable member 3 is provided with a sharp portion 33 for piercing the bottom of the material storage barrel 12, so that the movable member 3 can pierce the bottom of the material storage barrel 12 smoothly and quickly when moving downward.

[0033] As a further preferred embodiment, Figure 2 and Figure 3 As shown, the easy-tear portion 122 is arranged along the bottom edge of the storage barrel 12, and the easy-tear portion 122 is a thin-walled material with a reduced thickness arranged at the bottom of the storage barrel 12. As a further optimization, the sharp portion 33 is in the shape of a blade, and the easy-tear portion 122 is a ring structure, that is, the easy-tear portion 122 is an annular structure arranged between the bottom wall and the side wall of the storage barrel 12, and its center is consistent with the rotation center of the movable part 3, and the sharp portion 33 is correspondingly arranged above the easy-tear portion 122, as shown in FIG. Figure 6 As shown, the movable part 3 first presses against the easy-tear portion 122 during the sliding process, and then the blade-like sharp portion 33 cuts the bottom of the storage barrel 12 along the easy-tear portion 122 during the rotation of the movable part 3, so that the entire bottom of the storage barrel 12 is cut and separated from the main body.

[0034] As a preference, Figure 2 and Figure 3 As shown, in order to improve the strength of the bottom of the storage barrel 12, a convex or concave reinforcement portion 123 is provided in the middle of the storage barrel 12, and at least two reinforcement portions 123 are distributed along the circumference, so that the structural strength of the middle of the storage barrel 12 is higher and not easy to deform, and then when the movable part 3 moves downward, the middle of the storage barrel 12 will not be easily deformed, so that the easy-tear portion 122 is more easily punctured and torn. As a further optimization, such as Figure 6 As shown, the reinforcement portion 123 is distributed on one side of the easy-to-tear portion 122, and a guide surface 124 is provided on the top of the reinforcement portion 123, which gradually tilts downward from the direction away from the easy-to-tear portion 122 to the direction close to the easy-to-tear portion 122. In this way, during the rotation of the movable part 3, the deviation of the sharp portion 33 from the easy-to-tear portion 122 caused by material deformation can be avoided, and the deviated sharp portion 33 can be guided to the easy-to-tear portion 122, making the structural stability stronger.

[0035] In order to make the movable part 3 rotate when the silo cover 2 rotates without affecting the movable part 3 sliding up and down relative to the silo cover 2, as shown in FIG. Figure 2 and Figure 3 As shown, the silo cover 2 is provided with a mounting ring 21 extending into the inner side of the movable part 3, the mounting ring 21 is provided with a plurality of sliding slots 211 arranged along the up-down direction, and the inner side wall of the movable part 3 is provided with sliding ribs 32 arranged along the up-down direction and inserted into the sliding slots 211, so that the movable part 3 is driven to rotate when the silo cover 2 rotates.

[0036] In order to improve the strength of the structure, one of the sliding ribs 32 is disposed at a position corresponding to the sharp portion 33 .

[0037] As a preference, Figure 2 and Figure 3 As shown, the assembly protrusion 121 is a spiral convex strip, that is, the assembly protrusion 121 is not a complete spiral stripe, but a small segment of a spiral convex strip. As a further preferred embodiment, Figure 5 As shown, the movable part 3 is provided with a first blocking portion 34 located in the thread groove 31 and used to block the movement of the assembly protrusion 121 at the lower part, and the movable part 3 is provided with a second blocking portion 35 located in the thread groove 31 and used to block the movement of the assembly protrusion 121 at the upper part, and the second blocking portion 35 has a guide surface 351 for the assembly protrusion 121 to pass over the second blocking portion 35 when moving. In this way, when the movable part 3 rotates, it is blocked by the first blocking portion 34 and does not move upward, and after the movable part 3 rotates and moves upward, it is blocked by the second blocking portion 35, so that the resistance to twisting of the silo cover 2 is increased. After continuing to twist the silo cover 2, the assembly protrusion 121 can pass over the second blocking portion 35 through the guide surface 351, and then the movable part 3 slides down into place, and the user is given feedback of the damping sense through different resistances, so that the movable part 3 can slide down into place smoothly, and at the same time, the user is given a clear prompt 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 only needs to be placed in the main cover seat 1, making assembly more convenient.

[0038] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
