A bottle cap and container for storing mother liquor

Abstract

This invention relates to the field of bottle cap technology, providing a bottle cap and container for storing mother liquor. The bottle cap includes an inner cap and an inner sleeve for fitting onto the bottle opening. The inner cap and inner sleeve are threaded together. It also includes a liquid storage component with a storage cavity and an outlet hole. A sealing post is provided at the upper end of the inner cap, and the outlet hole is fitted onto the sealing post to seal the storage cavity. A liner is fixedly connected to the storage component. The liner has a spiral guide groove on its side wall, and the outer wall of the inner cap has a guide key matching the guide groove to achieve axial displacement when the liner rotates. An outer cap is fitted onto the outside of the storage component and the liner and is fixedly connected to the liner. When the outer cap is rotated to open the bottle cap initially, the inner cap remains stationary, and the liner rotates and moves upward with the outer cap, separating the outlet hole from the sealing post. The mother liquor stored in the storage cavity flows into the bottle. Further rotation of the outer cap completely opens the bottle cap. This invention enables the bottle cap to store mother liquor and release it upon opening, allowing it to mix with the sub-liquid in the bottle, thus expanding the functionality of the bottle cap.

Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, and more specifically, to a bottle cap and container for storing mother liquor. Background Technology

[0002] Currently, some beverage bottle caps (including alcoholic beverages and soft drinks) require the inclusion of a mother liquor (including but not limited to alcoholic liquids and powders) within the cap. The mother liquor must be stored inside the cap and not come into contact with the derivative liquor inside the bottle, allowing for mixing during use. However, most existing bottle caps do not have the function of storing the mother liquor. Therefore, how to provide a bottle cap capable of storing the mother liquor internally is a pressing technical problem that needs to be solved in this field. Summary of the Invention

[0003] The purpose of this invention is to meet market demand, expand the function of bottle caps, and provide a bottle cap and container for storing mother liquor.

[0004] This invention is achieved through the following technical solution:

[0005] A bottle cap for storing mother liquor includes an inner cap and an inner sleeve for fitting onto the bottle opening, the inner cap being connected to the inner sleeve via threads, and further includes:

[0006] The liquid storage component has a liquid storage cavity inside and a liquid outlet at the lower end of the liquid storage component. The upper end of the inner cover is provided with a sealing post, and the liquid outlet is sleeved on the sealing post to seal the liquid storage cavity.

[0007] A liner, fixedly connected to the liquid reservoir, has a spiral guide groove on its side wall, and a guide key on the outer wall of the inner cover that matches the guide groove, allowing axial displacement when the liner rotates; and

[0008] The outer cover is fitted over the liquid storage component and the liner and is fixedly connected to the liner. When the outer cover is rotated to open the bottle cap, the inner cover is fixed in place under the action of the thread torque. When the liner is rotated with the outer cover, it moves upward to separate the liquid outlet from the sealing column, so that the mother liquid stored in the liquid storage chamber flows into the bottle. After that, the outer cover can be rotated to separate the inner cover from the inner sleeve, so as to open the bottle cap.

[0009] Optionally, the lower end of the inner wall of the inner cover is provided with a limiting ring groove, and the outer wall of the inner sleeve is provided with a limiting bracket. When the inner cover is tightened, the limiting bracket and the limiting ring groove cooperate.

[0010] Optionally, each side wall of the guide groove is provided with a claw, and the distance between the two claws gradually decreases along the direction from the upper end to the lower end of the guide groove, so that when the liner rotates with the outer cover and moves upward, the claws pass the guide key and restrict the liner from rotating in the opposite direction.

[0011] Optionally, the outer wall of the inner cover is provided with a locking block, and the side wall of the liner is provided with a locking groove. When the inner cover is tightened, the locking block and the locking groove cooperate. After the liner moves upward relative to the inner cover, the locking groove and the locking block separate, and the locking block restricts the liner from moving downward.

[0012] Optionally, the slot is a blind slot provided on the inner wall of the liner, and the lower end of the slot penetrates the lower edge of the liner.

[0013] Optionally, the liquid storage component includes a liquid storage cap, a liquid storage cylinder with open upper and lower ends, and a sealing plug with the liquid outlet hole. The liquid storage cap is fixedly connected to the upper end of the liquid storage cylinder, and the sealing plug is fixedly connected to the lower end of the liquid storage cylinder.

[0014] Optionally, the outer cover includes an upper outer cover and a lower outer cover with openings at both ends. The upper outer cover is fixedly connected to the upper end of the lower outer cover and presses against the liquid storage cover.

[0015] Optionally, the inner wall of the lower outer cover is provided with a first anti-rotation tooth, and the outer wall of the liner is provided with a second anti-rotation tooth that engages with the first anti-rotation tooth;

[0016] The inner wall of the liner is provided with a third anti-rotation tooth, and the outer wall of the liquid storage cylinder is provided with a fourth anti-rotation tooth that cooperates with the third anti-rotation tooth.

[0017] The inner wall of the liner is provided with a first limiting platform, and the outer wall of the liquid storage cylinder is provided with a second limiting platform. The bottom surface of the first limiting platform abuts against the top surface of the second limiting platform to limit the upward displacement of the liquid storage cylinder relative to the liner.

[0018] A container comprising a bottle body and a cap for storing mother liquor as described in any of the preceding claims.

[0019] The technical solution of the present invention has at least the following advantages and beneficial effects: In the present invention, after the bottle cap is assembled, the liquid storage component, the outer cap, and the liner are equivalent to forming a whole. The mother liquor is stored inside the liquid storage component. When the outer cap is rotated to open the bottle cap, the inner cap is fixed under the action of the thread torque (that is, the thread torque between the inner cap and the inner sleeve is greater than the opening torque of the liner). Only the liquid storage component, the outer cap, and the liner rotate as a whole. Since the liner and the inner cap are connected by the guide key and the spiral guide groove, the guide groove of the liner slides along the guide key, so that the liner moves upward when it follows the rotation of the outer cap, thereby separating the liquid outlet from the sealing column. The mother liquor stored in the liquid storage chamber flows downward into the bottle body through the liquid outlet and mixes with the sub-liquid in the bottle body. After that, if a greater torque is applied to rotate the outer cap, the inner cap can be rotated, so that the inner cap and the inner sleeve are separated, thereby opening the bottle cap. As can be seen, compared with existing bottle caps, this invention enables the bottle cap to store the mother liquor, ensuring that the mother liquor does not come into contact with the daughter liquor in the bottle before the bottle cap is opened. When the bottle cap is opened, the mother liquor flows into the bottle first and mixes with the daughter liquor, thus expanding the function of the bottle cap and well meeting market demand.

Detailed Implementation

[0032] Example 1

[0033] refer to Figure 1 A bottle cap for storing mother liquor includes a liquid storage component 3, a liner 4, an outer cap 5, an inner cap 2, and an inner sleeve 1 for fitting onto the bottle opening.

[0034] refer to Figures 1-7 The inner cover 2 is connected to the inner sleeve 1 by threads. The liquid storage component 3 has a liquid storage cavity inside and a liquid outlet hole at the lower end of the liquid storage component 3. The upper end of the inner cover 2 is provided with a sealing post 201, and the liquid outlet hole is sleeved on the sealing post 201 to seal the liquid storage cavity. The liner 4 is fixedly connected to the liquid storage component 3. The side wall of the liner 4 is provided with a spiral guide groove 401. The outer wall of the inner cover 2 is provided with a guide key 202 that matches the guide groove 401 to achieve axial displacement when the liner 4 rotates. The outer cover 5 is sleeved on the outside of the liquid storage component 3 and the liner 4 and is fixedly connected to the liner 4.

[0035] Based on the above, after the bottle cap is assembled, the liquid storage component 3, the outer cap 5, and the liner 4 form a whole. The mother liquor is stored inside the liquid storage component 3. When the outer cap 5 is rotated to open the bottle cap, the inner cap 2 is fixed under the action of the thread torque (that is, the thread torque between the inner cap 2 and the inner sleeve 1 is greater than the opening torque of the liner 4). Only the liquid storage component 3, the outer cap 5, and the liner 4 rotate as a whole. Since the liner 4 and the inner cap 2 are connected to the spiral guide groove 401 through the guide key 202, the guide groove 401 of the liner 4 slides along the guide key 202, so that the liner 4 moves upward when it rotates with the outer cap 5, thereby separating the liquid outlet from the sealing column 201. The mother liquor stored in the liquid storage chamber flows downward into the bottle body 8 through the liquid outlet and mixes with the sub-liquid in the bottle body 8. After that, if a greater torque is applied to rotate the outer cap 5, the inner cap 2 can be rotated, so that the inner cap 2 is separated from the inner sleeve 1, thus opening the bottle cap. As can be seen, compared with existing bottle caps, the present invention enables the bottle cap to store the mother liquor, ensuring that the mother liquor does not come into contact with the sub-liquid in the bottle body 8 before the bottle cap is opened, and the mother liquor flows into the bottle body 8 to mix with the sub-liquid when the bottle cap is opened, which well meets the market demand.

[0036] It is worth noting that the directional terms "upper" and "lower" used in this invention refer to the state when the container is in use, placed upright on the support (i.e., the bottom of the bottle is in contact with the support, and the bottle opening is facing upwards). Furthermore, based on the above, it should be understood that to ensure that rotating the outer cap 5 when opening the bottle cap causes the liner 4 to rotate and rise accordingly, the guide key 202 should be located at the higher end of the guide groove 401 after the bottle cap is assembled (e.g., ...). Figure 8 As shown), when the cover 4 rises to its limit position, the guide key 202 is located at the lower end of the guide groove 401 (as shown). Figure 9 (As shown).

[0037] As can be seen from the above, the bottle cap opening process in this invention consists of two steps. The first step involves the overall rotation and upward movement of the liquid storage component 3, the outer cap 5, and the liner 4, releasing the mother liquor within the storage chamber. The second step involves the rotation of the inner cap 2, separating it from the inner sleeve 1, thus completing the entire bottle cap opening action. Based on this, if the thread torque between the inner cap 2 and the inner sleeve 1 is too small, it may cause the inner cap 2 to move prematurely (i.e., move before releasing the mother liquor). Therefore, this embodiment has made the following improvements: (Refer to...) Figure 1 , Figure 2 and Figure 5 The lower end of the inner wall of the inner cover 2 is provided with a limiting annular groove 203, and the outer wall of the inner sleeve 1 is provided with a limiting bracket 101. When the inner cover 2 is tightened, the limiting bracket 101 engages with the limiting annular groove 203. This arrangement, together with the thread torque, effectively limits the premature movement of the inner cover 2. It should be understood that the depth of the limiting annular groove 203 should not be too large, and should ensure that the limiting bracket 101 can disengage from the limiting annular groove 203 when the inner cover 2 rotates.

[0038] refer to Figure 8 and Figure 9 In this embodiment, each side wall of the guide groove 401 is provided with a claw 4011. The distance between the two claws 4011 gradually decreases along the direction from the upper end to the lower end of the guide groove 401. It should be understood that the liner 4 is made of plastic with a certain degree of elasticity. The claws 4011 are arranged as shown in the figure, allowing them to open to a certain extent. During the process of the liner 4 rotating and moving upwards along with the outer cap 5, the claws 4011 gradually open after contacting the guide key 202. After the claws 4011 pass the guide key 202, they restrict the reverse rotation of the liner 4, preventing the cap from being restored through reverse operation. This improves the anti-counterfeiting effect, even if the cap cannot be reused. Furthermore, during the process of opening the cap, after the claws 4011 pass the guide key 202, the guide key 202 is located at the lower end of the guide groove 401, and the claws 4011 rebound. The user can clearly feel the sound, making it easy to know that the mother liquor has begun to be released.

[0039] Refer again Figure 1 , Figure 4 and Figure 7In this embodiment, a locking block 204 is provided on the outer wall of the inner cover 2, and a locking groove 402 is provided on the side wall of the liner 4. When the inner cover 2 is tightened, the locking block 204 engages with the locking groove 402. After the liner 4 moves upward relative to the inner cover 2, the locking groove 402 separates from the locking block 204, and the locking block 204 restricts the liner 4 from moving downward. In this way, it also restricts the bottle cap from being restored by reverse operation, further improving the anti-counterfeiting effect. It should be understood that the locking block 204 should have a certain degree of elasticity. After the locking block 204 separates from the locking groove 402, the locking block 204 can open outward, thereby achieving the effect of restricting the liner 4 from moving downward. The specific setting method is not limited. In addition, a pair of locking blocks 204 can be symmetrically arranged on both sides of the inner cover 2 to ensure structural stability.

[0040] Furthermore, in this embodiment, the slot 402 is a blind slot provided on the inner wall of the cover 4, and the lower end of the slot 402 penetrates the lower edge of the cover 4. It is worth noting that this setting avoids the axial force generated by the cooperation between the card block 204 and the slot 402, which would increase the difficulty of moving the cover 4 upward.

[0041] refer to Figure 1 In this embodiment, the liquid storage component 3 includes a liquid storage cap 302, a liquid storage cylinder 301 with open upper and lower ends, and a sealing plug 303 with a liquid outlet. The liquid storage cap 302 is fixedly connected to the upper end of the liquid storage cylinder 301, and the sealing plug 303 is fixedly connected to the lower end of the liquid storage cylinder 301. The above-mentioned fixed connection can be a heat-pressed connection, or it can be directly snapped together, provided that the connection of the sealing box can be guaranteed to be stable. It can be fixed by means of buckles and grooves. For example, in this embodiment, the liquid storage cap 302 is connected to the liquid storage cylinder 301 by snapping, which is convenient for filling mother liquor. In practical applications, the size of the liquid storage cylinder 301 can also be set according to the actual liquid storage capacity requirements to meet different needs.

[0042] The outer cover 5 includes an upper outer cover 501 and a lower outer cover 502 with openings at both the upper and lower ends. The upper outer cover 501 is fixedly connected to the upper end of the lower outer cover 502 and presses against the liquid storage cap 302. Similarly, the fixed connection can be a heat-pressed connection or a direct snap-fit ​​connection, and can be fixed by means of buckles and grooves.

[0043] Based on the above, as an option, the fixed connection between the liner 4 and the liquid reservoir 3, and between the liner 4 and the outer cover 5, is achieved by restricting relative rotation in the circumferential direction and restricting relative movement in the axial direction. Specifically, refer to... Figure 1 , Figure 6 , Figure 10 and Figure 11The inner wall of the lower outer cover 502 is provided with a first anti-rotation tooth 5021, and the outer wall of the liner 4 is provided with a second anti-rotation tooth 403 that engages with the first anti-rotation tooth 5021. In this way, the relative rotation between the outer cover 5 and the liner 4 is restricted. The inner wall of the liner 4 is provided with a third anti-rotation tooth 404, and the outer wall of the liquid storage cylinder 301 is provided with a fourth anti-rotation tooth 3011 that engages with the third anti-rotation tooth 404. In this way, the relative rotation between the liquid storage component 3 and the liner 4 is restricted. At the same time, the inner wall of the liner 4 is provided with a first limiting platform 405, and the outer wall of the liquid storage cylinder 301 is provided with a second limiting platform 3012. The bottom surface of the first limiting platform 405 abuts against the top surface of the second limiting platform 3012. In this way, the upward displacement of the liquid storage cylinder 301 relative to the liner 4 is restricted. Since the outer cover 5 covers the liquid storage component 3, it is also equivalent to restricting the relative displacement between the outer cover 5 and the liner 4. In other embodiments, other methods can of course be used to achieve the fixed connection, such as heat pressing.

[0044] Furthermore, it should be understood that the meshing between the anti-rotation teeth can be understood as meshing in the traditional sense (i.e., the meshing between two gears), so that there is no relative rotation between the two parts; or it can be understood as the anti-rotation teeth on the two parts being arranged in a cross pattern, allowing the two parts to have a small angle of relative rotation.

[0045] Example 2

[0046] This embodiment provides a container, which in practical applications includes, but is not limited to, wine bottles, beverage bottles, etc. The container includes a bottle body 8 and a bottle cap provided in Embodiment 1 for storing mother liquor. In practical applications, it also includes an inner plug 6, which is fixedly connected (e.g., heat-pressed) to the inside of the inner sleeve 1 and embedded in the bottle mouth. In order to make the appearance more aesthetically pleasing, an outer sleeve 7 can also be fitted over the inner sleeve 1. The outer sleeve 7 and the outer cap 5 together wrap the rest of the bottle cap parts, which serves as protection and decoration.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art.
