[0003] Currently, there are many functional caps on the market, composed of multiple parts, especially the filling chamber, which is formed by combining three separate parts. For example... Figure 1 As shown, the container cap consists of an upper cap 1, a cutter 3, and a lower cap 2. The cutter is hollow inside and opens vertically, forming a chamber for filling contents when it is fitted with the upper cap. The lower cap 2 fits with the upper cap 1. The cutter 3 is located inside the upper cap 1 and the lower cap 2, and is separated from the chamber in the lower cap 2 by an aluminum foil film, thus forming the container cap of the prior art.

The second cylinder of the lower cover is located inside the inner cylinder of the upper cover, and the first cylinder of the lower cover is located outside the inner cylinder of the upper cover, thereby connecting the filling chamber with the lower cover cavity and the discharge cavity, so that the filling material in the filling chamber flows out through the lower cover cavity and the discharge cavity.

[0018] Preferably, the inner wall of the filling chamber has a folded film baffle, which extends along the depth direction and is located near the upper surface of the sealing film in the opposite direction to the depth direction, and there is a gap between the folded film baffle and the inner wall of the filling chamber in the radial direction.

[0019] Preferably, the inner wall of the upper cover mating chamber has an upper cover anti-rotation baffle, and the upper cover anti-rotation baffle is located below the internal thread of the upper cover along the depth direction. The outer wall of the lower cover has a lower cover anti-rotation baffle, and the lower cover anti-rotation baffle is located above the external thread of the lower cover along the opposite direction of the depth direction.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0027] 1. Because the container cap of this utility model is placed on a predetermined container, the predetermined container having a container opening and a container bottom, with the direction from the container opening to the container bottom defined as the depth direction; it includes a lower cap and an upper cap that cooperate with each other along the depth direction, and further includes: an inner cylinder of the upper cap, integrally formed with the upper cap and extending along the depth direction, and inserted into the lower cap, the length of the inner cylinder of the cap in the depth direction being greater than the length of the upper cap in the depth direction, and a filling chamber opening toward the container opening being formed inside the inner cylinder of the upper cap; and a sealing film, disposed at the bottom of the inner cylinder of the upper cap along the depth direction and sealing the filling chamber. Reverse cutting teeth are formed on the lower cover and located between the container opening and the sealing membrane. The purpose is to make the inner cylinder of the upper cover and the upper cover an integral piece. The entire container cover has only two separate parts, the upper cover and the lower cover. Compared with the prior art, it has one less separate part, thus eliminating the precision requirements of manufacturing three parts separately and avoiding the high requirements for the consistency of the three parts. Therefore, the airtightness is reliable. After opening, the entire container cover can be separated from the container opening, and consumers can still drink from the container opening, which increases the consumer experience, simplifies the product, and ensures high airtightness. The container cover is simple to assemble, has low production cost, and high assembly efficiency.

[0028] In addition, when the aluminum foil is cut by the reverse cutting teeth and rolled upward in the opposite direction of the volume depth, the aluminum foil can be folded and pressed tightly against the inner wall of the filling chamber by the resistance of the folding film baffle. The aluminum foil is not easily observed to swing or slip on the aluminum foil when it is stored in the filling chamber. In order to better restrict the shredded aluminum foil to the inner wall of the filling chamber.

[0029] 2. Because the upper cover of this utility model has an upper cover mating chamber, the inner cylinder of the upper cover is located in the upper cover mating chamber, the inner wall of the upper cover mating chamber has an upper cover internal thread, and the outer wall of the lower cover has a lower cover external thread. The upper cover internal thread and the lower cover external thread are mated. The purpose is to guide the upper cover to move along the depth direction through the mating of the upper cover internal thread and the lower cover external thread, and to accurately position the distance the upper cover moves along the depth direction, and also to prevent the upper cover from being over-tightened.

[0030] 3. Because the lower cover of this utility model has a first lower cover cylinder that extends along the depth direction and has a lower cover cavity inside the first lower cover cylinder, a second lower cover cylinder that is concentrically arranged with the lower cover cavity and located inside the first lower cover cylinder, the second lower cover cylinder that extends in the opposite direction of the depth direction, and reverse cutting teeth are provided at the end of the second lower cover cylinder and correspond to the sealing membrane in the opposite direction of the depth direction; the lower cover also has a lower cover mating chamber that communicates with the lower cover cavity and corresponds to the upper cover mating chamber;

[0031] When the inner cylinder of the upper cover is inserted into the inner cylinder of the lower cover, and the inner thread of the upper cover mates with the outer thread of the lower cover, the mating chamber of the lower cover is connected to the mating chamber of the upper cover. At this time, the inner cylinder of the upper cover extends into the mating chamber of the lower cover and the lower cover cavity in sequence along the depth direction, so that the filling chamber extends into the cavity of the lower cover.

[0032] Additionally, when the reverse cutting teeth are located near the sealing membrane, the lower cover cavity and the filling chamber are separated by the sealing membrane.

[0033] When the inner cylinder of the upper cover moves along the depth direction in the lower cover mating chamber and the lower cover cavity, until the top surface of the upper cover mating chamber touches the top surface of the lower cover mating chamber, the upper cover ends its travel along the depth direction, and the reverse cutting teeth have cut the aluminum foil film. The second cylinder of the lower cover is located inside the inner cylinder of the upper cover, and the first cylinder of the lower cover is located outside the inner cylinder of the upper cover, thereby connecting the filling chamber with the lower cover cavity and the discharge cavity, so that the filling material in the filling chamber flows out through the lower cover cavity and the discharge cavity.

[0034] 4. Because the inner wall of the filling chamber of this utility model has a folding film baffle, and the folding film baffle extends along the depth direction and is located near the upper surface of the sealing film in the opposite direction of the depth direction, and there is a gap between the folding film baffle and the inner wall of the filling chamber in the radial direction; the purpose is that when the aluminum foil film is cut by the reverse cutting teeth and rolled up in the opposite direction of the depth direction, the folding film baffle can block the aluminum foil film, fold it tightly against the inner wall of the filling chamber, and the aluminum foil film is not easily observed to swing or the contents slip off the aluminum foil film when it is stored in the filling chamber.

[0035] 5. Because the upper cover of this utility model has an anti-rotation baffle on the inner wall of the cavity, and the anti-rotation baffle is located below the inner thread of the upper cover along the depth direction, and the lower cover has an anti-rotation baffle on the outer wall of the lower cover, and the anti-rotation baffle is located above the outer thread of the lower cover along the opposite direction of the depth direction, the anti-rotation baffle of the upper cover and the anti-rotation baffle of the lower cover correspond to each other, the purpose of which is to prevent the upper cover from reaching the designated position and then being screwed back to the original position.

[0036] 6. Because the lower cover of this utility model has a third cylindrical body on its outer periphery, the third cylindrical body extends along the depth direction, and a flat surface is provided on the third cylindrical body connected to the outer periphery of the lower cover. A lower cover anti-rotation baffle is provided on the upper surface of the flat surface; an anti-theft ring is fixedly connected to the upper cover, and the anti-theft ring extends along the depth direction and is located below the upper cover anti-rotation baffle. The anti-theft ring has a breakable notch, which is open towards the flat surface. The circumferential surface of the third cylindrical body of the lower cover has short stripes, which extend along the depth direction and are connected to the outer periphery of the lower cover. The purpose of the fragility notch matching is that, with the upper cover moving along the depth direction through the threaded engagement of the upper cover's internal thread with the lower cover's external thread, when the upper cover moves downward a specified distance and approaches the plane on the lower cover, that is, when the inner top surface of the upper cover touches the top surface of the lower cover, it will burst open and fall off to both sides due to the presence of the fragility notch. When it is screwed to the specified position, the upper cover cannot be screwed back to its original position, and it can only move in one direction. If it moves in the opposite direction from the beginning, it will damage the bridge point connecting the anti-theft ring and the upper cover.

[0037] 7. Because the lower cover of this utility model forms a step between the cavity and the first cylinder of the lower cover, a sealing ring is provided on the lower surface of the step along the depth direction, and the sealing ring is located on the outer periphery of the first cylinder of the lower cover. Both the sealing ring and the step seal the mouth of the container, effectively preventing the liquid in the bottle from leaking out when the container is dropped or inverted.

[0047] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0048] like Figure 4 As shown, a novel container lid is placed on a predetermined container 4. The predetermined container 4 has a container opening 41 and a container bottom. The direction from the container opening 41 to the container bottom is defined as the depth direction A.

[0049] like Figure 2-3 As shown, the device includes a lower cover 2 and an upper cover 1 that cooperate with each other along the depth direction. Specifically, the upper cover 1 has an upper cover mating chamber 11, and the upper cover inner cylinder 5 is located in the upper cover mating chamber 11. The inner wall of the upper cover mating chamber 11 has an upper cover internal thread 111, and the outer wall of the lower cover 2 has a lower cover external thread 23. The upper cover internal thread 111 and the lower cover external thread 23 are mated. The purpose is to guide the upper cover to move along the depth direction A through the mating of the upper cover internal thread 111 and the lower cover external thread 23, and to accurately position the movement distance of the upper cover 1 along the depth direction A, and also to prevent the upper cover 1 from being over-tightened.

[0050] like Figure 4-5As shown, the inner cylinder 5 of the upper cover is integrally formed with the upper cover 1 and extends along the depth direction A. The purpose is that the inner cylinder 5 and the upper cover 1 are a single unit, thus ensuring a more reliable airtightness compared to existing technologies. After opening, the entire container lid can detach from the container opening 41, allowing consumers to still drink from the opening 41, enhancing the consumer experience, simplifying the product, and ensuring high airtightness. Furthermore, when inserted into the lower cover 2, the length of the inner cylinder 5 in the depth direction is greater than that of the upper cover 1 in the depth direction. The inner cylinder 5 of the upper cover has a filling chamber 6 that opens towards the container opening 41. A sealing film 7 is provided at the bottom of the inner cylinder 5 along the depth direction A and seals the filling chamber 6. The purpose is to weld the aluminum foil film 7 to the bottom of the inner cylinder 5 of the upper cover to seal the filling chamber 6. After sealing, it plays a very good sealing role for the filling in the filling chamber 6 and extends the shelf life of the filling. Reverse cutting teeth 8 are formed on the lower cover 2 and are located between the container opening 41 and the sealing film 7.

[0051] Specifically: such as Figure 6-7 As shown, the lower cover 2 has a lower cover mating chamber 24 and a lower cover first cylinder 21. The lower cover mating chamber 24 is connected to the lower cover first cylinder 21 along the depth direction A. The lower cover first cylinder 21 extends along the depth direction A and has a lower cover cavity 211 inside. The lower cover mating chamber 24 is connected to the lower cover cavity 211 and corresponds to the upper cover mating chamber 11. When the upper cover inner cylinder 5 is inserted into the lower cover first cylinder 21, and when the upper cover inner thread 111 is engaged with the lower cover outer thread 23, the lower cover mating chamber 24 is connected to the upper cover mating chamber 11. The upper cover inner cylinder 5 extends sequentially into the lower cover mating chamber 24 and the lower cover cavity 211 along the depth direction A, thereby allowing the filling chamber 6 to extend into the lower cover cavity 21. In step 1, when the reverse cutting tooth 8 is located near the sealing membrane 7, the lower cover cavity 211 and the filling chamber 6 are blocked by the sealing membrane 7. When the upper cover inner cylinder 5 moves along the depth direction A in the lower cover mating chamber 24 and the lower cover cavity 211 until the top surface of the upper cover mating chamber 11 touches the top surface of the lower cover mating chamber 24, the upper cover 1's stroke along the depth direction A ends, and the reverse cutting tooth 8 has cut the aluminum foil 7. The lower cover second cylinder 22 is located inside the upper cover inner cylinder 5, and the lower cover first cylinder 21 is located outside the upper cover inner cylinder 5, thereby connecting the filling chamber 6 with the lower cover cavity 211 and the discharge cavity 221, so that the filling material in the filling chamber 6 flows out through the lower cover cavity 211 and the discharge cavity 221.

[0052] like Figure 6-7As shown, the lower cover 2 also includes a lower cover second cylinder 22, which is concentrically arranged with the lower cover cavity 211. The lower cover second cylinder 22 has a discharge cavity 221, which is open along the depth direction A and the opposite direction of the depth direction A and is located inside the lower cover first cylinder 21. The lower cover second cylinder 22 extends along the opposite direction of the depth direction A, and the reverse cutting teeth 8 are provided at the end of the lower cover second cylinder 22. Specifically, when the aluminum foil film 7 is cut by the reverse cutting teeth 8, the broken aluminum foil film 7 moves towards the filling chamber 6 with the reverse cutting teeth 8 and enters the filling chamber 6. That is, the broken aluminum foil film 7 moves along the opposite direction of the depth direction A, thereby connecting the filling chamber 6 with the lower cover cavity 211, the discharge cavity 221 and the outside of the lower cover 2, so that the material in the filling chamber 6 flows out through the lower cover cavity 211 and the discharge cavity 221.

[0053] Additionally, the lower cover cavity 211 located outside the lower cover second cylinder 22 is open along the depth direction A, that is, the lower cover second cylinder 22 has a drain port 212 at the bottom along the depth direction A. The drain port 212 is connected to the container opening 41. The purpose is that when the predetermined container 4 (e.g., a bottle) is tilted or dropped, liquid may flow into the area between the bottom of the upper cover 1 and the reverse cutting tooth 8, resulting in liquid residue. The drain port 212 can drain the liquid here and merge it with the liquid in the predetermined container 4 (e.g., a bottle). In order to facilitate drainage, multiple drain ports 212 can be set at this location.

[0054] The inner wall of the filling chamber 6 has a folding film baffle 9, which extends along the depth direction A and is located near the upper surface of the sealing film 7 in the opposite direction of the depth direction A. There is a gap between the folding film baffle 9 and the inner wall of the filling chamber 6 in the radial direction. In this embodiment, the gap is 1-5 mm. The purpose of setting the folding film baffle 9 is to fold the aluminum foil film 7 tightly against the inner wall of the filling chamber 6 by the blocking of the folding film baffle 9 when the aluminum foil film 7 is cut by the reverse cutting teeth 8 and rolled up in the opposite direction of the depth direction A. The aluminum foil film 7 is not easily observed to swing or the contents to slip off the aluminum foil film 7. In order to better restrict the shredded aluminum foil film 7 to the inner wall of the filling chamber 6, multiple folding film baffles 9 can be set, and they can be set in a full circle or half circle along the inner wall of the filling chamber 6.

[0055] The inner wall of the upper cover mating chamber 11 has an upper cover anti-rotation baffle 112, and the upper cover anti-rotation baffle 112 is located below the upper cover internal thread 111 along the depth direction A. The outer wall of the lower cover 2 has a lower cover anti-rotation baffle 25, and the lower cover anti-rotation baffle 25 is located above the lower cover external thread 23 along the opposite direction of the depth direction A. The upper cover anti-rotation baffle 112 and the lower cover anti-rotation baffle 25 correspond to each other. The purpose is to prevent the upper cover 1 from reaching the designated position and then being screwed back to the original position. In order to better play the role of prevention, multiple upper cover anti-rotation baffles 12 and lower cover anti-rotation baffles 25 can be provided, and the number of both is the same.

[0056] The lower cover 2 has a lower cover third cylinder 26 on its outer periphery. The lower cover third cylinder 26 extends along the depth direction A. The lower cover third cylinder 26 connected to the outer periphery of the lower cover 2 has a plane 261. The lower cover anti-rotation baffle 25 is provided on the upper surface of the plane 261. A protrusion 262 is provided along the circumference of the lower cover third cylinder 26 to facilitate the rotation of the lower cover 2.

[0057] The upper cover 1 is fixedly connected with an anti-theft ring 10. Specifically, the bottom of the upper cover 1 extending along the depth direction A is connected to the anti-theft ring 10 through a bridge point. The anti-theft ring 10 extends along the depth direction A and is located below the upper cover anti-rotation baffle 211. The anti-theft ring 10 is provided with a breakable notch 101, which is open to the plane 261. The lower cover third cylinder 26 is also provided with a lower cover short stripe 28 on its circumference. The lower cover short stripe 28 extends along the depth direction A and corresponds to the breakable notch 101. The lower cover short stripe 28 is located between two adjacent protrusions 262.

[0058] The inner wall of the anti-theft ring 10 has an anti-theft ring anti-rotation baffle 102, which extends along the depth direction A. The purpose is that when the upper cover 1 moves along the depth direction A through the threaded engagement of the upper cover internal thread 111 with the lower cover external thread 23 on the lower cover 2, when the upper cover 1 moves down a specified distance and approaches the plane 261 on the lower cover 2, that is, when the inner top surface of the upper cover 1 touches the top surface of the lower cover 2, it will break off to both sides due to the presence of the fragility notch 101 when it contacts the plane 261 on the lower cover 2. When it is screwed to the specified position, the upper cover 1 cannot be screwed back to its original position, and it can only move in one direction. If it moves in the opposite direction at the beginning, it will destroy the bridge point connecting the anti-theft ring 10 and the upper cover 1.

[0059] The lower cover 2 has a lower cover skirt 27, which extends along the depth direction A. The inner surface of the lower cover skirt 27 is threadedly engaged with the outer wall of the container opening 41, and the lower cover first cylinder 21 is connected to the container opening 41. Specifically, the lower cover skirt 27 is a cylinder extending along the depth direction A, and the lower cover skirt 27 is coaxial with the lower cover first cylinder 21. The container opening 41 is threadedly engaged with the inner surface of the lower cover skirt 27, and the container opening 41 is located between the lower cover skirt 27 and the lower cover first cylinder 21.

[0060] In addition, such as Figure 2 As shown, a step 29 is formed between the lower cover mating chamber 24 and the lower cover first cylinder 21. A sealing ring 30 is provided on the lower surface of the step 29 along the depth direction A, and the sealing ring 30 is located on the periphery of the lower cover first cylinder 21. Both the sealing ring 30 and the step 29 seal the container opening 41, effectively preventing the liquid in the bottle from leaking out when the predetermined container 4 is dropped or inverted.

[0061] It should be noted that the upper cover 1 of this container is made of PE, and the lower cover 2 is made of PP.

[0062] The container lid is operated as follows:

[0063] exist Figure 8 From step a to step 8b, after the contents are filled into the upper cover 1, an aluminum foil film 7 is welded to the bottom plate of the inner cylinder 5 of the upper cover to seal the filling chamber 6. The upper cover 1 and the lower cover 2 are threaded together and rotated clockwise, that is, the inner thread 111 of the upper cover and the outer thread 23 of the lower cover are engaged, so that the upper cover 1 moves along the depth direction A until the upper cover 1 moves close to the plane 261 on the lower cover 2. Then, the breakable notch 101 of the anti-theft ring 10 is aligned with the short stripe 28 of the lower cover (as shown in the image). Figure 2 As shown), the upper cover 1 and the lower cover 2 are assembled; unscrew the protrusion 262 on the cover 2 to make the lower cover 2 threadedly fit with the container opening 41, rotate clockwise, and tighten. The container cover is then assembled with the predetermined container 4.

[0064] exist Figure 8 During the process from b to 8a, when unscrewing the container lid, rotate the upper lid 1 clockwise. The upper lid 1 moves along the thread of the lower lid 2 in the direction of container depth A to reach the designated position. During the movement, the anti-theft ring 10 is squeezed by the upper lid 1 and the lower lid 2 and moves to both sides (taking the breakage notch 101 of the anti-theft ring 10 as the front view, the anti-theft ring 10 breaks off from the upper lid 1 and falls to the left and right). Figure 2 As shown by the left and right arrows in the figure, the foil film 7 is broken off and the reverse cutting teeth 8 in the lower cover 2 cuts through the aluminum foil film 7. Under the action of the film folding baffle 9, it is drawn in the opposite direction of the volume depth A and adheres tightly to the inner wall of the filling chamber 6.

[0065] When the upper cover 1 moves a specified distance along the depth direction A and approaches the plane 261 on the lower cover 2, that is, when the inner top surface of the upper cover 1 touches the top surface of the lower cover 2, the stroke ends. The upper cover anti-rotation baffle 112 and the lower cover anti-rotation baffle 25 have blocked each other. At this time, the upper cover 1 and the lower cover 2 are combined into a whole. The contents are torn by the aluminum foil film 7 but not cut through it. (It should be noted that the process of the aluminum foil film 7 being cut by the reverse cutting teeth 8 is as follows: During the movement of the upper cover 1 along the depth direction, when the aluminum foil film 7 touches the reverse cutting teeth 8, the upper cover 1 continues to move along the depth direction A.) The reverse cutting tooth 8 is set to two-thirds of a circle in the second cylinder 22 of the lower cover. When the reverse cutting tooth 8 penetrates the aluminum foil film 7 to a specified depth, the reverse cutting tooth 8 is pierced and reaches the surface of the folding film baffle 9. It continues to move, and under the upward pushing force of the reverse cutting tooth 8 and the pushing force of the folding film baffle 9 along the direction of the inner cylinder 5 of the upper cover, the aluminum foil film 7 moves upward, that is, towards the inner wall of the filling chamber 6. The remaining one-third circle of aluminum foil film 7 is not cut by the reverse cutting tooth 8, and is still connected to the inner cylinder 5 of the upper cover to prevent the aluminum foil film 7 from falling into the predetermined container 4. After the foil 7 moves along the inner wall of the filling chamber 6, the contents begin to fall. After the upper cover 1 finishes its stroke, the aluminum foil 7 will stick tightly to the wall containing the contents. At this point, the contents have basically fallen into the predetermined container 4, and the upper cover 1 and lower cover 2 have been connected as a single unit. The contents fall into the liquid in the predetermined container 4 through the channel of the lower cover 1. That is, when the inner cylinder 5 of the upper cover is inserted into the first cylinder 21 of the lower cover, and when the inner thread 111 of the upper cover and the outer thread 23 of the lower cover are engaged, the lower cover engagement chamber 24 is connected to the upper cover engagement chamber 11, and the inner cylinder of the upper cover... 5. The filling chamber 6 extends into the lower cover cavity 24 and the lower cover cavity 211 in sequence along the depth direction A, thereby extending the filling chamber 6 into the lower cover cavity 211. This connects the filling chamber 6 with the lower cover cavity 211, the discharge cavity 221, and the outside of the lower cover 2, allowing the contents of the filling chamber 6 to flow out through the lower cover cavity 211 and the discharge cavity 221. Then, by rotating the container cap counterclockwise, the container cap can be removed from the container opening 41. Drinking is done from the container opening 41, just like drinking ordinary mineral water. Tightening the container cap is the same as tightening an ordinary cap, simply by turning it clockwise.

[0066] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
