[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1 A bottle cap comprises: a cap body 100, a positioning structure 170, a connecting structure 300 and a film-lifting structure 400, wherein the cap body 100 is provided with an inner cavity 130, and the inner cavity 130 has an opening 150 connected to the outside; the positioning structure 170 is arranged in the inner cavity 130 and can be docked with the bottle mouth of the bottle, and the positioning structure 170 is provided with a accommodating cavity 175; the connecting structure 300 is arranged in the inner cavity 130, and the connecting structure 300 is located between the end of the inner cavity 130 away from the opening 150 and the opening 150, and the connecting structure 300 is used to connect the cap body 100 to the bottle; the film-lifting structure 400 is arranged at the opening 150, and when the cap body 100 leaves the bottle and makes the opening 150 move to the diaphragm of the bottle, the film-lifting structure 400 can lift the diaphragm and drive the diaphragm to move away from the bottle. When the cover 100 covers the outer periphery of the bottle mouth through the opening 150, the bottle mouth can be received in the inner cavity 130 of the cover 100, thereby achieving a sealing effect on the bottle mouth. When the bottle cap seals the bottle mouth, the positioning structure 170 will dock with the bottle mouth. Therefore, even if the contents of the bottle expand due to temperature changes or pressure changes, the cover 100 can load the contents of the bottle through the accommodating cavity 175, thereby effectively preventing the contents of the bottle from overflowing, thereby effectively improving the sealing effect and stability of the bottle cap on the bottle mouth. When the bottle mouth needs to be opened, it can first perform reverse movement according to the connection action of the connection structure 300, so that the cover 100 can leave the bottle mouth. During this process, the opening 150 will gradually move to the membrane at the bottle mouth, and the membrane will be lifted quickly and directly through the membrane lifting structure 400, so that the cover body 100 can automatically lift the membrane at the bottle mouth when leaving the bottle mouth, thereby making the opening action of the bottle mouth more convenient and faster, thereby effectively improving the use and opening experience of the bottle cap.

[0027] It is conceivable that the cover 100 has an outer profile that facilitates the application of torque thereto, such as a gear-shaped outer profile. The specific implementation is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0028] In certain embodiments, reference Figure 2 The positioning structure 170 includes a positioning boss 173 disposed in the inner cavity 130. The positioning boss 173 protrudes outward relative to the inner wall of the inner cavity 130. The positioning boss 173 can contact the bottle mouth of the bottle through its end away from the wall of the inner cavity 130. After the bottle mouth is installed in the inner cavity 130, the end of the bottle mouth will abut against the positioning boss 173, so the positioning boss 173 can effectively achieve the positioning effect of the bottle mouth, thereby ensuring that the contents of the bottle can flow smoothly and accurately into the accommodating cavity 175 when flowing out, so as to avoid the problem of leakage of the contents of the bottle.

[0029] In certain embodiments, reference Figure 2 The positioning boss 173 extends from the top of the inner cavity 130 toward the bottom of the inner cavity 130, and the opening 150 is located at the bottom of the inner cavity 130; the accommodating cavity 175 is connected to the bottom of the positioning boss 173. The positioning boss 173 and the opening 150 are respectively located at the top and bottom ends of the cover body 100, so the space of the inner cavity 130 can be effectively used to store and seal the bottle mouth. In addition, the opening 150 and the positioning boss 173 distributed at both ends also allow the positioning boss 173 to contact the end of the bottle mouth more smoothly, and avoid the positioning boss 173 from extending to the surrounding side of the bottle mouth by mistake, so the positioning accuracy of the positioning boss 173 can be effectively improved.

[0030] In certain embodiments, reference Figure 2 The side of the positioning boss 173 is provided with a support portion 177, which extends to and is connected to the side wall of the inner cavity 130. The support portion 177 can support the positioning boss 173 from the side of the positioning boss 173, thereby ensuring that the positioning boss 173 can stably dock with the bottle mouth, thereby avoiding the problem that the positioning boss 173 is pushed toward the side and deformed when the bottle mouth and the positioning boss 173 are in contact, and improving the positioning stability of the positioning boss 173.

[0031] In certain embodiments, reference Figure 2 The positioning boss 173 is cylindrical, and the supporting parts 177 are multiple and distributed around the positioning boss 173. The cylindrical positioning boss 173 can achieve the positioning and abutting effect on the bottle mouth from all directions, and each supporting part 177 can support the positioning boss 173 from different sides of the positioning boss 173, so the problem of the positioning boss 173 bending and tilting to one side can be effectively avoided.

[0032] It is conceivable that the positioning boss 173 may also extend directly from the side wall of the inner cavity 130 to the middle of the inner cavity 130, rather than only protruding from the top of the inner cavity 130. The specific implementation is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0033] In certain embodiments, reference Figure 2 The connection structure 300 is located between the positioning structure 170 and the film lifting structure 400. The location of the connection structure 300 allows it to connect the bottle mouth after the bottle body passes through the opening 150, and the connected bottle mouth can smoothly contact the positioning structure 170, so that the bottle mouth can be wrapped and sealed smoothly.

[0034] In certain embodiments, reference Figure 2The connection structure 300 includes an internal thread disposed on the inner wall of the inner cavity 130, and the cover body 100 can be threadedly connected to the bottle mouth of the bottle through the connection structure 300. The internal thread can be threadedly engaged with the external thread at the bottle mouth, thereby achieving a connection effect between the cover body 100 and the bottle mouth. The threaded connection method has the advantage of easy assembly and disassembly, so that the bottle mouth can be opened more conveniently and quickly.

[0035] It is conceivable that the connection structure 300 can also be a block and a slot, and the cover 100 is connected to the bottle mouth through the clamping action between the block and the slot. Therefore, the specific implementation of the connection structure 300 is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0036] In certain embodiments, reference Figure 3 The film lifting structure 400 includes a sawtooth portion 450 disposed at the opening 150, and the sawtooth portion 450 extends from the edge of the opening 150 toward the center of the opening 150. During the movement of the cover 100, the sawtooth portion 450 will gradually move to contact the diaphragm, and insert its outer contour between the diaphragm and the bottle. When the sawtooth portion 450 moves further, its outer contour will lift the diaphragm, thereby directly and effectively achieving the effect of directly lifting the diaphragm when the cover 100 moves, thereby making the bottle opening operation more convenient and quick.

[0037] It is conceivable that the connection structure 300 may also be composed of other components, such as by providing adhesive at the opening 150 and using adhesive force to drive the membrane away from the bottle mouth. The specific implementation is not unique, but can be adjusted accordingly according to actual conditions, and is not limited here.

[0038] In certain embodiments, reference Figure 3 The opening 150 is located at the bottom of the cover 100, and the serration 450 extends obliquely from the bottom of the cover 100 toward the top of the cover 100. The serration 450 extends toward the top of the cover 100, so that its end can more conveniently contact the portion of the membrane extending outward from the edge of the bottle mouth. In addition, the inclined serration 450 is also easier to insert into the gap between the membrane and the bottle mouth, so that the serration 450 can smoothly lift the membrane from the bottle mouth.

[0039] In certain embodiments, reference Figure 3The edge of the opening 150 is provided with an avoidance notch 430 for the serration 450 to bend or bend. When the cover 100 is installed on the bottle mouth, the bottle body will press the serration 450, thereby ensuring that the cover 100 can be smoothly installed on the bottle body. In this process, the serration 450 can be bent or bend through the avoidance notch 430, thereby ensuring that the cover 100 can be smoothly installed on the bottle mouth of the bottle body, thereby smoothly achieving the sealing effect of the bottle mouth.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
