Description

Technical Field

[0001] The present invention relates to the technical field of bottle caps, and in particular to a bottle cap and a container capable of storing mother liquid. Background Art

[0002] At present, some bottle caps of beverages (including alcoholic beverages, etc.) want to have a mother liquid (including but not limited to alcoholic liquid, powder, etc.) built in, requiring the mother liquid to be stored in the bottle cap without contacting the sub-liquid in the bottle body, and to be able to mix the mother liquid with the sub-liquid in the bottle body during use. However, most of the existing bottle caps do not have the function of storing the mother liquid. Therefore, how to provide a bottle cap that can store the mother liquid inside is a technical problem that needs to be solved urgently in the art. Summary of the invention

[0003] The purpose of the present invention is to meet market demand, expand the function of the bottle cap, and provide a bottle cap and a container capable of storing mother liquid.

[0004] The present invention is achieved through the following technical solutions:

[0005] A bottle cap capable of storing mother liquid comprises an inner cap and an inner sleeve for being sleeved on a bottle mouth, wherein the inner cap is connected to the inner sleeve through a thread, and further comprises:

[0006] A liquid storage member, wherein the liquid storage member has a liquid storage cavity inside and a liquid outlet hole is provided at the lower end of the liquid storage member, a sealing column is provided at the upper end of the inner cover, and the liquid outlet hole is sleeved on the sealing column to seal the liquid storage cavity;

[0007] A lining cover is fixedly connected to the liquid storage member, a side wall of the lining cover is provided with a spiral guide groove, and an outer wall of the inner cover is provided with a guide key matching the guide groove, so as to achieve axial displacement when the lining cover rotates; and

[0008] The outer cover is sleeved on the outside of the liquid storage part and the lining cover and is fixedly connected to the lining cover. When the outer cover is rotated to open the bottle cap, the inner cover is fixed under the action of the threaded torque, and the lining cover moves upward as the outer cover rotates to separate the liquid outlet from the sealing column, so that the mother liquid stored in the liquid storage chamber flows into the bottle body, and then the outer cover is continued to be rotated to separate the inner cover from the inner sleeve, thereby opening the bottle cap.

[0009] Optionally, a limiting ring groove is provided at the lower end of the inner wall of the inner cover, and a limiting hanging platform is provided on the outer wall of the inner sleeve. When the inner cover is tightened, the limiting hanging platform cooperates with the limiting ring groove.

[0010] Optionally, a claw is provided on each side wall of the guide groove, 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 lining cover rotates with the outer cover and moves upward, the claws limit the reverse rotation of the lining cover after passing over the guide key.

[0011] Optionally, a block is provided on the outer wall of the inner cover, and a slot is provided on the side wall of the lining cover. When the inner cover is tightened, the block cooperates with the slot, and after the lining cover moves upward relative to the inner cover, the slot separates from the block, and the block restricts the lining cover from moving downward.

[0012] Optionally, the card slot is a blind slot provided on the inner wall of the lining cover, and the lower end of the card slot passes through the lower edge of the lining cover.

[0013] Optionally, the liquid storage component includes a liquid storage cover, a liquid storage cylinder with open upper and lower ends, and a sealing plug with the liquid outlet hole, the liquid storage cover 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 comprises an upper outer cover and a lower outer cover with upper and lower ends open, and the upper outer cover is fixedly connected to the upper end of the lower outer cover and presses 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 lining cover is provided with a second anti-rotation tooth engaged with the first anti-rotation tooth;

[0016] The inner wall of the lining cover 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 cooperating with the third anti-rotation tooth;

[0017] The inner wall of the lining cover 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 lining cover.

[0018] A container comprises a bottle body and any one of the above-mentioned bottle caps capable of storing mother liquid.

[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 part, the outer cover and the lining cover are equivalent to forming a whole, and the mother liquid is stored inside the liquid storage part. When the outer cover is initially rotated to open the bottle cap, the inner cover is fixed under the action of the threaded torque (that is, the threaded torque between the inner cover and the inner sleeve is greater than the swing torque of the lining cover), and only the liquid storage part, the outer cover and the lining cover are rotated as a whole. Since the lining cover and the inner cover are connected through the guide key and the spiral guide groove, the guide groove of the lining cover slides along the guide key, so that the lining cover moves upward when the outer cover rotates, thereby separating the liquid outlet from the sealing column, and the mother liquid 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. Thereafter, continuing to apply a larger torque to rotate the outer cover can drive the inner cover to rotate, separate the inner cover from the inner sleeve, and open the bottle cap. It can be seen that compared with the existing bottle cap, the present invention enables the bottle cap to store mother liquid, ensuring that the mother liquid does not contact the sub-liquid in the bottle body before the bottle cap is opened. When the bottle cap is opened, the mother liquid first flows into the bottle body and mixes with the sub-liquid, thereby expanding the function of the bottle cap and meeting the market demand well.

DETAILED DESCRIPTION

[0032] Example 1

[0033] refer to Figure 1 A bottle cap for storing mother liquid comprises a liquid storage part 3, a lining cover 4, an outer cover 5, an inner cover 2 and an inner sleeve 1 for being sleeved on the bottle mouth.

[0034] refer to Figure 1-Figure 7 The inner cover 2 is connected to the inner sleeve 1 through a thread, the liquid storage part 3 has a liquid storage cavity inside and a liquid outlet is provided at the lower end of the liquid storage part 3, and a sealing column 201 is provided at the upper end of the inner cover 2, and the liquid outlet is sleeved on the sealing column 201 to close the liquid storage cavity; the lining cover 4 is fixedly connected to the liquid storage part 3, and the side wall of the lining cover 4 is provided with a spiral guide groove 401, and the outer wall of the inner cover 2 is provided with a guide key 202 matching the guide groove 401 to achieve axial displacement when the lining cover 4 rotates; the outer cover 5 is sleeved on the outside of the liquid storage part 3 and the lining cover 4 and is fixedly connected to the lining cover 4.

[0035] On the basis of the above, after the bottle cap is assembled, the liquid storage part 3, the outer cover 5 and the lining cover 4 are equivalent to forming a whole, and the mother liquid is stored inside the liquid storage part 3. When the outer cover 5 is rotated to open the bottle cap, the inner cover 2 is fixed under the action of the threaded torque (that is, the threaded torque between the inner cover 2 and the inner sleeve 1 is greater than the swing torque of the lining cover 4). Only the liquid storage part 3, the outer cover 5 and the lining cover 4 are rotated as a whole. Since the lining cover 4 and the inner cover 2 are connected with the spiral guide groove 401 through the guide key 202, the guide groove 401 of the lining cover 4 slides along the guide key 202, so that the lining cover 4 moves upward when following the rotation of the outer cover 5, thereby separating the liquid outlet from the sealing column 201, and the mother liquid stored in the liquid storage cavity flows downward into the bottle body 8 through the liquid outlet and mixes with the sub-liquid in the bottle body 8. Thereafter, continue to apply a larger torque to rotate the outer cover 5, which can drive the inner cover 2 to rotate, separate the inner cover 2 from the inner sleeve 1, and open the bottle cap. It can be seen that compared with the existing bottle cap, the present invention enables the bottle cap to store mother liquid, ensuring that the mother liquid does not contact the sub-liquid in the bottle body 8 before the bottle cap is opened. When the bottle cap is opened, the mother liquid first flows into the bottle body 8 and mixes with the sub-liquid, which well meets the market demand.

[0036] It is worth noting that the directional terms "up" and "down" in the present invention refer to the state in which the container is placed on the support when in use (i.e., the bottle bottom is in contact with the support and the bottle mouth is facing upward). In addition, based on the above, it should be understood that in order to ensure that the outer cover 5 can be rotated to make the lining cover 4 rotate and rise when the bottle cap is opened, the guide key 202 should be located at the higher end of the guide groove 401 (such as Figure 8 As shown in FIG. 1 , when the lining cover 4 rises to the limit position, the guide key 202 is located at the lower end of the guide groove 401 (as shown in FIG. 1 ). Fig. 9 shown).

[0037] As can be seen from the above, the process of opening the bottle cap in the present invention is divided into two processes. The first process is the overall rotation and rise of the liquid storage part 3, the outer cover 5 and the lining cover 4 to release the mother liquid in the liquid storage chamber; the second process is the rotation of the inner cover 2 to separate the inner cover 2 from the inner sleeve 1 to complete the entire bottle cap opening action. On this basis, if the thread torque between the inner cover 2 and the inner sleeve 1 is too small, it may cause the inner cover 2 to move in advance (i.e., move before releasing the mother liquid). For this reason, this embodiment has made the following improvements: again referring to Figure 1 , Figure 2 and Figure 5 The lower end of the inner wall of the inner cover 2 is provided with a limit ring groove 203, and the outer wall of the inner sleeve 1 is provided with a limit hanging platform 101. When the inner cover 2 is tightened, the limit hanging platform 101 cooperates with the limit ring groove 203. Such a setting, together with the thread torque, well limits the early movement of the inner cover 2. It should be understood that the depth of the limit ring groove 203 should not be too large, and it should be ensured that when the inner cover 2 rotates, the limit hanging platform 101 can be separated from the limit ring groove 203.

[0038] refer to Figure 8 and Fig. 9 In this embodiment, a claw 4011 is provided on each side wall of the guide groove 401. 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 lining cover 4 is made of plastic with a certain elasticity. The claws 4011 are arranged in the manner shown in the figure. The claws 4011 can be opened to a certain extent. When the lining cover 4 rotates and moves upward following the outer cover 5, the claws 4011 gradually open after contacting the guide key 202. After the claws 4011 pass over the guide key 202, the lining cover 4 is restricted from rotating in the opposite direction, so that the bottle cap cannot be restored by reverse operation, even if the bottle cap cannot be used again, the anti-counterfeiting effect is improved. In addition, when the user opens the bottle cap, after the claws 4011 pass over the guide key 202, the guide key 202 is located at the lower end of the guide groove 401, and the claws 4011 rebound at the same time. The user can clearly feel the sound, which is convenient for knowing that the mother liquid has been released at this time.

[0039] Reference again Figure 1 , Figure 4 and Figure 7In this embodiment, a block 204 is provided on the outer wall of the inner cover 2, and a slot 402 is provided on the side wall of the lining cover 4. When the inner cover 2 is tightened, the block 204 cooperates with the slot 402, and after the lining cover 4 moves upward relative to the inner cover 2, the slot 402 separates from the block 204, and the block 204 restricts the lining cover 4 from moving downward. In this way, the bottle cap can also be restored by reverse operation, further improving the anti-counterfeiting effect. It should be understood that the block 204 should have a certain elasticity. After the block 204 is separated from the slot 402, the block 204 can be opened outward, so as to achieve the effect of restricting the lining cover 4 from moving downward. The specific setting method is not limited. In addition, a pair of blocks 204 can be symmetrically arranged on both sides of the inner cover 2 to ensure structural stability.

[0040] Furthermore, the slot 402 of this embodiment is a blind slot provided on the inner wall of the lining cover 4, and the lower end of the slot 402 passes through the lower edge of the lining cover 4. It is worth noting that such a setting avoids the block 204 and the slot 402 from producing axial force and increasing the difficulty of moving the lining cover 4 upward.

[0041] refer to Figure 1 In this embodiment, the liquid storage part 3 includes a liquid storage cover 302, a liquid storage cylinder 301 with open ends at the upper and lower ends, and a sealing plug 303 with a liquid outlet. The liquid storage cover 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 hot compression connection, and it can also be directly buckled together under the premise of ensuring that the sealing box connection is stable, and fixed by means of buckles and buckle grooves. For example, the liquid storage cover 302 of this embodiment is connected to the liquid storage cylinder 301 by buckling, which is convenient for filling the mother liquid. In actual 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 which is open at both ends. The upper outer cover 501 is fixedly connected to the upper end of the lower outer cover 502 and presses the liquid storage cover 302. Similarly, the fixed connection can be a hot pressing connection, or it can be directly buckled together and fixed by means of buckles and buckle grooves.

[0043] On the basis of the above, as an option, the fixed connection between the liner 4 and the liquid storage member 3, and between the liner 4 and the outer cover 5 is achieved by limiting the relative rotation in the circumferential direction and limiting the relative movement in the axial direction. Specifically, refer to Figure 1 , Figure 6 , Fig.10 and Fig.11The inner wall of the lower outer cover 502 is provided with a first anti-rotation tooth 5021, and the outer wall of the lining cover 4 is provided with a second anti-rotation tooth 403 engaged with the first anti-rotation tooth 5021, so that the relative rotation between the outer cover 5 and the lining cover 4 is limited; the inner wall of the lining cover 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 engaged with the third anti-rotation tooth 404, so that the relative rotation between the liquid storage part 3 and the lining cover 4 is limited. At the same time, the inner wall of the lining cover 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, and the bottom surface of the first limiting platform 405 is against the top surface of the second limiting platform 3012, so that the upward displacement of the liquid storage cylinder 301 relative to the lining cover 4 is limited. Since the outer cover 5 wraps the liquid storage part 3, it is also equivalent to limiting the relative displacement between the outer cover 5 and the lining cover 4. In other embodiments, other methods may be used to achieve fixed connection, such as heat pressing.

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

In order to make the appearance beautiful, an outer sleeve 7 can also be provided on the outside of the inner sleeve 1. The outer sleeve 7 and the outer cover 5 together wrap the remaining parts of the bottle cap to play a protective and decorative role.
