[0002] With the development of society, beverages such as cola, tea, juice and liquor have become part of people's daily life. Bottle caps are an important part of food, beverage and wine bottle packaging. They are also the first place where consumers come into contact with the product. Usually, water and special ingredients are mixed on the production line and then filled into the bottle, and the bottle is sealed with an integrated bottle cap.

[0003] The Chinese patent with the publication number of "CN 219361918 U" discloses "a fresh-keeping packaging cover", which includes an upper cover and a lower cover, wherein the upper cover is arranged at the top opening of the lower cover, and a sealing film is arranged in the lower cover to enclose a storage chamber between the upper cover, the lower cover and the sealing film; a cutter is arranged in the storage chamber; a driving block is arranged on the cutter, a driving blade extending downward is arranged on the top inner wall of the upper cover, and a driving slide is formed along the side edge of the driving blade, and a first positioning part and a second positioning part are respectively arranged on the upper cover and the cutter; when the upper cover and the lower cover are in an assembled state, the first positioning part and the second positioning part are located at preset relative positions; when the upper cover is in a screwed upward state, the driving slide is in contact with the corresponding position. The driving blocks on the device are abutted, and the driving blades push the driving block to rotate and move downward along the driving slide to push the cutter to rotate and move downward and cut the sealing film. The utility model solves the technical problem that the fresh-keeping packaging cover is easily assembled without various assembly parts. The patent adopts an overly complex structure, which increases the production cost, and the overly complex structure requires higher structural precision. The slightest deviation will cause the opening process to be laborious, and there is no corresponding anti-dropping structure after the bottle cap is opened, which will cause the bottle cap to be lost during use, causing pollution to the environment and not being environmentally friendly. For this reason, we propose a split storage fresh-keeping bottle cap. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a split storage fresh-keeping bottle cap, comprising a base, a cutting ring and a top cover, wherein the cutting ring is screwed on the upper side of the inner cavity of the base, the top cover is screwed on the upper side of the outer wall of the base, an inner reverse thread is opened around the upper side of the inner cavity wall of the base, an aluminum film paper is bonded to the inner cavity wall of the base and located below the inner reverse thread, a first stopper is fixedly connected to the upper side of the left and right side walls of the inner cavity of the cutting ring, and a The outer side is reversely threaded, and the outer side is reversely threaded with the inner side reversely threaded. The bottom of the cutting circle is provided with serrations. The bottom of the top cover is fixedly connected with an anti-theft ring. The bottom of the top cover and the top of the anti-theft ring are provided with open grooves, and the open grooves are evenly distributed. A flip groove is provided between the lower side of the front side wall of the top cover and the upper side of the front side wall of the anti-theft ring. The left and right sides of the top of the inner cavity of the top cover are fixedly connected with second blocks, and the second block is in contact with the vertical surface of the first block.

[0006] As a further description of the above technical solution:

[0007] An outer positive thread is formed on the upper side of the outer wall of the base, a limiting ring is fixedly connected to the outer wall of the base and located below the outer positive thread, and a first inner positive thread is formed around the lower side of the inner cavity wall of the base.

[0008] As a further description of the above technical solution:

[0009] A second inner positive thread is formed around the inner wall of the top cover, and the second inner positive thread is threadedly connected with the outer positive thread.

[0010] As a further description of the above technical solution:

[0011] The second stopper and the first stopper are located at the same center of a circle, and the saw teeth occupy between four fifths and three fifths of the length of the bottom of the cutting circle.

[0012] As a further description of the above technical solution:

[0013] The lower side of the outer wall of the base and the outer wall of the top cover are both provided with protective lines.

[0014] As a further description of the above technical solution:

[0015] The top of the scribing ring is flush with the top of the base, and the top of the scribing ring, the top of the base and the top of the inner cavity of the top cover are in contact.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The split storage fresh-keeping bottle cap forms a shell chamber for accommodating objects through the sealing of the aluminum film paper on the base, the cutting ring and the top cover. The material is added into the chamber and the top cover is rotated counterclockwise. The top cover is opened under the action of the outer positive thread and the second inner positive thread. When the top cover is rotated and opened, the first block is driven to move by the second block, and the first block drives the cutting ring to rotate clockwise. The cutting ring rotates under the action of the inner reverse thread and the outer reverse thread, and the aluminum film paper is cut by the saw teeth to transfer the material into the container. Then the top cover is closed and the container is shaken to merge with the material. Thus, the aluminum film paper can be opened by the cutting ring when the top cover is opened through a simple structure. The simple structure makes opening more convenient and labor-saving, and also reduces the production cost.

[0018] 2. For the split storage fresh-keeping bottle cap, when the top cover is opened, the anti-theft ring at the bottom of the top cover is separated from the top cover through the opening groove under the action of the limit ring, and the top cover and the anti-theft ring form a soft connection under the action of the flip groove. When the top cover is opened during use, the top cover will not be separated from the base under the action of the anti-theft ring, thereby avoiding pollution to the environment caused by the loss of the bottle cap, which is more environmentally friendly.
