Description

Technical Field

[0001] The utility model relates to the technical field of container bottle caps, in particular to a separable storage bottle cap and its bottle body added to mineral water. Background Art

[0002] Bottled beverages have the advantages of being convenient to carry, having rich flavors, and being ready to drink immediately. They are a kind of portable beverage commonly consumed in modern society. Common beverage bottles consist of two parts: a bottle cap and a bottle body. The bottle cap and the bottle mouth of the bottle body are commonly engaged by threads. The bottle cap can be tightened to seal the bottle body or loosened to drink, which is very convenient. Bottled beverages generally consist of a solvent and a solute. Due to reasons such as long transportation distances and long storage times, when producing beverages, most manufacturers will add food additives to the solvent in the traditional way to increase the storage period of the beverage and maintain the taste. However, with the change of life concepts, consumers have a new understanding of beverage food additives and hope to reduce the use of food additives. Therefore, a bottle cap capable of storing solutes has emerged. Its characteristic is that the solute can be stored inside the bottle cap, so that the solute and the solvent are stored separately. When drinking, the solute will be released into the solvent to form a beverage when the bottle cap is unscrewed. The method of storing the solvent and the solute separately can avoid the defect that traditional beverages need to use food additives to extend the taste of the beverage, thus avoiding the use of food additives and making the beverage more natural and healthy. However, currently, the bottle caps capable of storing solvents still need to be improved in terms of structure. For example, some bottle caps have loose structures, resulting in cumbersome and discontinuous opening and drinking actions. Some bottle caps need to be unscrewed as a whole to drink, which is likely to cause secondary pollution of the bottle mouth during multiple drinks. Therefore, how to improve the bottle cap structure is the problem to be solved by this invention. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the problems in the prior art that the bottle caps for storing solvents have loose structures, resulting in cumbersome and discontinuous opening actions, etc. Furthermore, a separable storage bottle cap and its bottle body added to mineral water are provided, which not only improve the tightness of the bottle cap but also enhance the continuity of the opening action.

[0004] To solve the above technical problems, the utility model provides a separable storage bottle cap added to mineral water, including,

[0005] A sleeve, the inner wall of which is convexly provided with a limiting block and a limiting strip. The limiting strip extends along the axis of the sleeve, and the outer wall of the upper end of the sleeve is provided with a first external thread;

[0006] A rotating cylinder is coaxially received inside the sleeve. An annular limiting body is coaxially provided on the outer wall of the rotating cylinder, and a plurality of ratchet teeth are evenly distributed on the annular limiting body. The ratchet teeth are arranged corresponding to the limiting strips, and the two form a ratchet structure capable of one-way rotation. The outer wall of the upper end of the rotating cylinder is provided with a second external thread, and the ratchet teeth are arranged to be able to abut against the bottom of the limiting block;

[0007] A cover body, the inner wall of which is provided with a first internal thread corresponding to the first external thread; an inner cover body is also fixedly provided inside the cover body, and the inner wall of the inner cover body is provided with a second internal thread corresponding to the second external thread. Among them, the pitches of the first external thread and the first internal thread are both smaller than the pitches of the second external thread and the second internal thread.

[0008] In an embodiment of the present invention, the upper and lower ends of the sleeve are respectively provided with an upper opening and a lower opening, and a material storage cavity communicating with the upper opening and the lower opening is further provided inside the sleeve, and the lower opening is sealed by a flexible sealing sheet.

[0009] In an embodiment of the present invention, the end of the lower opening is provided with a spiked inclined surface.

[0010] In an embodiment of the present invention, a plurality of the limiting strips are included, and the plurality of limiting strips are evenly distributed on the inner wall of the sleeve.

[0011] In an embodiment of the present invention, a liquid inlet is provided on the side wall of the rotating cylinder, and the liquid inlet extends along the axial direction of the rotating cylinder.

[0012] In an embodiment of the present invention, the lower half of the inner wall of the sleeve radially protrudes inward to form a tightening portion, and the limiting block is located on the tightening portion.

[0013] In an embodiment of the present invention, the limiting strip is provided with an inclined surface, and the inclined surface is smoothly connected with the surface of the tightening portion.

[0014] In an embodiment of the present invention, the limiting strip protrudes from the tightening portion to form an abutting portion, and the ratchet teeth are arranged to be able to abut against the abutting portion.

[0015] In an embodiment of the present invention, a third internal thread is provided on the inner wall of the lower end of the sleeve.

[0016] To solve the above problems, a bottle body is provided, which is connected to the separable storage type bottle cap installed on the mineral water. The bottle body is provided with a bottle mouth, and the outer wall of the bottle mouth is provided with a third external thread, and the third external thread is threadedly connected with the third internal thread.

[0017] The above technical solutions of the present invention have the following beneficial effects compared with the prior art:

[0018] The separable storage cap added to mineral water described in the present utility model utilizes the ratchet structure formed by ratchet teeth and limit strips, and the pitch difference between the pitch of the first external thread and the first internal thread and the pitch of the second external thread and the second internal thread, so that when the cap body rotates forward, the rotating cylinder can be driven to rise, and when it rotates backward, the rotating cylinder can be driven to descend. When opening the cap, the lower end of the rotating cylinder breaks through the lower opening of the sleeve downward, releasing the solute into the bottle body to realize the mixing of the solvent and the solute. It not only realizes the separated storage of the solvent and the solute, but also improves the coherence between the cap-opening action and the solute-releasing action. A limit block is arranged in the sleeve. When opening the cap, as the lower end of the rotating cylinder breaks through the lower opening of the sleeve downward, the annular limiting body and ratchet teeth of the rotating cylinder finally move downward to be under the limit block, thereby ensuring that the lower end of the rotating cylinder always breaks through the lower opening of the sleeve. This is not only conducive to the complete release of the solute into the bottle body, but also prevents the rotating cylinder from leaving the sleeve following the cap body, further improving the coherence of the cap-opening action. The solvent in the bottle body can flow through the lower ends of the sleeve and the rotating cylinder to the upper ends of the sleeve and the rotating cylinder, enabling the beverage to be drunk after removing the cap body without removing the entire separable storage cap, thus avoiding secondary pollution of the bottle mouth of the bottle body.

[0029] Embodiment

[0030] Referring to Figure 1 、 3 As shown in FIGS. 5 and 6, in an embodiment of the present utility model, a separable storage type bottle cap added to mineral water is disclosed, including

[0031] A sleeve 1, with a limiting block 18 and a limiting strip 16 protruding from its inner wall. The limiting strip 16 extends along the axis of the sleeve 1, and a first external thread 14 is provided on the outer wall of the upper end of the sleeve 1

[0032] A rotating cylinder 2, which is coaxially received inside the sleeve 1 and there is a gap for the solvent to flow between the two. The rotating cylinder 2 can rotate clockwise relative to the sleeve 1. An annular limiting body 26 and a plurality of ratchet teeth 23 evenly distributed on the annular limiting body 26 are coaxially provided on the outer wall of the rotating cylinder 2. The ratchet teeth 23 are arranged corresponding to the limiting strip 16 and the two form a ratchet structure that can rotate in one direction only. This ratchet structure enables the rotating cylinder 2 to only rotate clockwise relative to the sleeve 1 and cannot rotate counterclockwise. A second external thread 22 is provided on the outer wall of the upper end of the rotating cylinder 2. The ratchet teeth 23 and the annular limiting body 26 are arranged to be able to abut against the bottom of the limiting block 18, and the purpose is to limit the rotating cylinder 2 through the limiting block 18 to prevent the rotating cylinder 2 from detaching from the upper end of the sleeve 1. Further, through holes of upper openings 21 and lower openings 25 are provided at the upper and lower ends of the rotating cylinder 2

[0033] A cover body 3, the inner wall of which is provided with a first internal thread 31 corresponding to the first external thread 14; an inner cover body 32 is also fixedly connected inside the cover body 3, the inner wall of the inner cover body 32 is provided with a second internal thread 33 corresponding to the second external thread 22, and the inner cover body 32 extends out of the cover body 3, so that the length of the second internal thread 33 is greater than that of the first internal thread 31. When the cover body 3 is connected to the upper end of the sleeve 1, the second external thread 22 first contacts and connects with the second internal thread 33, and then the first external thread 14 connects with the first internal thread 31. Among them, the pitches of the first external thread 14 and the first internal thread 31 are both smaller than the pitches of the second external thread 22 and the second internal thread 33. When the cover body 3 is rotated forward (tightening the cover body 3), the sleeve 1 is synchronously rotated forward under the drive of the second internal thread 33, and the rotating cylinder 2 moves upward (rises) toward the upper end of the sleeve 1 until the set position. At this time, the cover body 3 is completely tightened. When the cover body 3 is rotated backward (loosening the cover body 3), the sleeve 1 is held tightly by the hand, and under the drive of the second internal thread 33 and the limitation of the limiting strip 16, the rotating cylinder 2 is pushed downward (descends) by the cover body 3 toward the lower end of the sleeve 1 until the set position. At this time, the ratchet teeth 23 and the annular limiting body 26 move to the set position, that is, located at the bottom of the limiting block 18 and limited by the limiting block 18, preventing the rotating cylinder 2 from being taken out together with the cover body 3, and the cover body 3 is completely loosened. Due to the pitch difference, the descending distance of the rotating cylinder 2 is greater than the ascending distance, so the lower end of the rotating cylinder 2 can break through the lower opening 11 of the sleeve 1, and then release the solute into the bottle body.

[0034] In an embodiment of the present invention, referring to Figure 2 and 3 As shown, upper openings 17 and a lower opening 11 are respectively provided at the upper and lower ends of the sleeve 1. A storage cavity communicating with the upper opening 17 and the lower opening 11 is also provided inside the sleeve 1. The storage cavity is used for storing solvents (such as honey or powdery materials), etc., and the lower opening 11 is sealed by a colloid and a flexible seal 4 to prevent the solute from leaking. When the cover body 3 is rotated backward, the rotating cylinder 2 moves toward the lower end of the sleeve 1 and its lower end can pierce the flexible seal 4 to release the solute into the bottle body below, and the solvent (such as water) in the bottle body flows through the lower opening 11 of the sleeve 1 and the rotating cylinder 2, the lower opening 21 to the upper opening 21 and the lower opening 17 and finally flows out of the bottle cap. The flexible seal 4 is preferably made of plastic.

[0035] In an embodiment of the present invention, referring to Figure 6 As shown, in order to pierce from the edge of the seal 4, the end of the lower opening 25 is provided with a spiked inclined surface 27, so that the tip of the spiked inclined surface 27 is aligned with the edge of the seal 4. The spiked inclined surface 27 is an end surface obtained by obliquely cutting the rotating cylinder 2.

[0036] In an embodiment of the present invention, referring to Figure 4As shown, it includes four of the limiting bars 16. The four limiting bars 16 are evenly distributed circumferentially on the inner wall of the sleeve 1. Correspondingly, four ratchet teeth 23 are evenly distributed on the annular limiting body 26. One ratchet tooth 23 is arranged between two adjacent limiting bars 16. When the rotating cylinder 2 rotates forward, the ratchet tooth 23 can slide over the limiting bar 16. When the rotating cylinder 2 rotates backward, the ratchet tooth 23 abuts against the limiting bar 16 and is blocked from rotating backward. Thus, the rotating cylinder 2 cannot continue to rotate backward and can only slide toward one end of the lower opening 11 of the sleeve 1 under the push of the second internal thread 33.

[0037] In an embodiment of the present invention, referring to Figure 6 As shown, a liquid inlet 24 is provided on the side wall of the rotating cylinder 2. The liquid inlet 24 extends along the axial direction of the rotating cylinder 2 and is used to accelerate the solvent in the bottle body to enter the rotating cylinder 2.

[0038] In an embodiment of the present invention, referring to Figure 3 As shown, the lower half of the inner wall of the sleeve 1 radially protrudes inward to form a tightening portion 12. The four limiting blocks 18 are evenly distributed axially on the tightening portion 12. The tightening portion 12 is conducive to making the solute more concentrated. There is a gap between the tightening portion 12 and the annular limiting body 26, and this gap is conducive to the flow of the solvent.

[0039] In an embodiment of the present invention, referring to Figure 3 As shown, the side surface of the limiting bar 16 is an inclined surface 15 arranged obliquely. The inclined surface 15 is smoothly connected to the surface of the tightening portion 12. The inclined surface 15 is conducive to the ratchet tooth 23 sliding over the limiting bar 16.

[0040] In an embodiment of the present invention, referring to Figure 7 As shown, the limiting bar 16 protrudes from the tightening portion 12 to form an abutting portion 19. The abutting portion 19 and the inclined surface 15 are respectively located on both sides of the limiting bar 16 along the circumferential direction of the rotating cylinder 2. After the rotating cylinder 2 rotates slightly backward, the ratchet tooth 23 can abut against the abutting portion 19 and is blocked by the abutting portion 19 from rotating backward.

[0041] In an embodiment of the present invention, referring to Figure 2 As shown, the inner wall of the lower end of the sleeve 1 is provided with a third internal thread 13. The bottle cap can be connected to the bottle mouth of the bottle body through the third internal thread 13. The bottle cap can be used on bottle bodies with different capacities and types, improving the compatibility of the bottle cap.

[0042] To solve the above problems, a bottle body is provided. The bottle body is connected to the separable storage type bottle cap installed on the mineral water. The inside of the bottle body is filled with a solvent. The bottle body is provided with a bottle mouth, and the outer wall of the bottle mouth is provided with a third external thread. The third external thread is threadedly connected to the third internal thread 13.

[0043] The working principle of the separable storage cap installed on the mineral water of the present utility model is as follows:

[0044] When encapsulating the separable storage cap, first seal the lower opening 11 of the sleeve 1 through the sealing piece 4, then place the rotating cylinder 2 into the sleeve 1, then put the solute into the storage cavity of the sleeve 1, and then rotatably connect the cap body 3 to the upper end of the sleeve 1 in the positive direction. The second external thread 22 is first connected to the second internal thread 33, and then the first external thread 14 is connected to the first internal thread 31 to completely seal the storage cavity. After the cap is encapsulated, the entire cap is connected to the bottle mouth of the bottle body. When drinking, hold the sleeve 1 tightly and rotatably connect the cap body 3 in the reverse direction. At the same time, the lower end of the rotating cylinder 2 moves towards the bottle body side, and finally the spike inclined surface 27 of the rotating cylinder 2 pierces the sealing piece 4, and the solvent flushes into the solvent in the bottle body. The annular limiting body 26 and the ratchet teeth 23 are located below the limiting block 18 and are limited. After shaking the bottle body to fully mix the solvent and the solute, then remove the cap body 3 to drink. When covering the cap body 3 again, the second internal thread 33 will drive the rotating cylinder 2 to rotate and rise, and the annular limiting body 26 and the ratchet teeth 23 will rotate circumferentially and finally rise above the limiting body 18.

[0045] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the creation of the present utility model.
