[0029] The specific implementation modes of the present utility model are introduced with reference to the accompanying drawings.
[0030] refer to Figure 1 The figure is a schematic diagram of the three-dimensional structure of an integrated anti-theft bottle cap. The integrated anti-theft bottle cap is a circular bottle cap formed by integral plastic injection molding. From top to bottom, it comprises an upper cover 2, a connecting ring 3 and an anti-theft ring 1. The anti-theft ring 1 is tightly fitted with the bottle mouth 101. After being assembled with the bottle mouth 101, it is difficult to separate it from the bottle mouth 101, thereby achieving an anti-theft effect. The connecting ring 3 is used to connect the upper cover 2 and the anti-theft ring 1, and the upper cover 2 is used to cover and seal the bottle mouth 101.
[0031] refer to Figures 1 to 8 , an integrated anti-theft bottle cap, comprising an anti-theft ring 1, an upper cover 2 and a connecting ring 3 which are integrally injection-molded, the inner wall of the anti-theft ring 1 being provided with a circle of protrusions 11 which are engaged with the first outer step 102 of the bottle mouth 101 to form an anti-theft structure, the connecting ring 3 being located between the upper cover 2 and the anti-theft ring 1, the connecting ring 3 comprising a tear strip 4 and a flip connecting portion 5, and an easily-tearable connecting groove 41 being provided between the tear strip 4 and the upper cover 2, the anti-theft ring 1 and the flip connecting portion 5; in the anti-theft state, the upper cover 2 and the anti-theft ring 1 are connected by the tear strip 4 and the flip connecting portion 5; when an external force pulls the tear strip 4 for unsealing, the tear strip 4 is separated from between the upper cover 2 and the anti-theft ring 1 through the broken connecting groove 41, so as to form an unsealed state in which the upper cover 2 and the anti-theft ring 1 are connected only by the flip connecting portion 5.
[0032] The integrated anti-theft bottle cap of the embodiment of the present application adopts an integrated injection molding structure. The assembly of the bottle cap and the bottle is completed as long as the whole is clamped at the bottle mouth 101 of the bottle. The production process and the assembly process are simple. The anti-theft of the bottle mouth 101 is achieved by a circle of protrusions 11 on the inner wall of the anti-theft ring 1. The upper cover 2 is connected to the anti-theft ring 1 through the flip connection part 5 and the tear strip 4. The tear strip 4 is used for unsealing. After unsealing, the upper cover 2 is flipped and set at the bottle mouth 101 through the flip connection part 5 and the anti-theft ring 1.
[0033] In order to seal the bottle, in this embodiment, reference Figure 3 , Figure 5 and Figure 6 The upper cover 2 is concentrically provided with a sealing ring 21, and the sealing ring 21 and the inner side wall of the upper cover 2 form a sealing groove 23 that is engaged with the bottle mouth 101. The sealing ring 21 is provided with a circle of convex ring 22 protruding toward one side of the sealing groove 23. The convex ring 22 is interference fit with the inner wall of the bottle mouth 101 under the elastic action of the sealing ring 21 itself.
[0034] It can be understood that, with such a configuration, the size of the sealing ring 21 must match the bottle mouth 101, the thickness of the bottle mouth 101 must match the thickness of the sealing groove 23, and when the upper cover 2 is buckled on the bottle mouth 101, the end face of the bottle mouth 101 contacts the bottom of the sealing groove 23, the sealing ring 21 extends into the bottle mouth 101, and the convex ring 22 has an interference fit with the inner wall of the bottle mouth 101, thereby sealing the bottle mouth 101 to ensure that the liquid in the bottle will not leak.
[0035] In order to buckle the upper cover 2 on the bottle, in this embodiment, refer to Figure 6 The inner side wall of the upper cover 2 is provided with a plurality of protrusions 24 which are engaged with the second outer step 103 of the bottle mouth 101 , and the protrusions 24 are not provided at the position where the upper cover 2 is connected with the flip connection part 5 .
[0036] It is understandable that, with such a configuration, the height of the protrusion 24 is relatively small, which is much smaller than the height of the protrusion 11, and the number of the protrusions 24 is also relatively small, which ensures that the upper cover 2 is buckled on the bottle mouth 101, while also making it convenient to open the upper cover 2 so that the upper cover 2 can be flipped relative to the bottle mouth 101, making it convenient to use the bottle cap.
[0037] In order to facilitate opening the upper cover 2, in this embodiment, refer to Figure 1 and Figure 7 The upper cover 2 is provided with a toggle groove 25 on the outer wall on the other side opposite to the flip connection portion 5 .
[0038] It can be understood that, with such a configuration, the toggle groove 25 is opened outward, the toggle groove 25 is relatively long, and it is convenient for fingers to apply force. The toggle groove 25 is arranged relative to the flip connection part 5, and the upper cover 2 can be opened by toggling the finger in the direction away from the bottle mouth 101, and then the upper cover 2 is flipped to the side of the bottle mouth 101 with the flip connection part 5 as the flip center.
[0039] In order to successfully realize the unsealing, in this embodiment, reference Figure 1 and Figure 2 The tear strip 4 is provided with a tear head 42 along the thickness direction of the upper cover 2. The tear head 42 is integrally formed on the outer side of the upper cover 2. A groove 26 is provided between the tear head 42 and the outer wall of the upper cover 2. The groove 26 forms a notch 27 at the end surface of the upper cover 2 for fingers to clamp the tear head 42. A groove 44 is recessed on the surface of the tear head 42.
[0040] The tear strip 42 is preferably pulled apart by the fingers when the bottle cap is opened, and the tear strip 42 is preferably pulled apart when the bottle cap is opened.
[0041] In order to connect the upper cover 2 and the anti-theft ring 1 only by turning over the connecting portion 5 after unsealing, in this embodiment, Figure 1 The tear head 42 and the tear tail 43 at both ends of the tear strip 4 are both set to be L-shaped, and both extend toward the end surface direction of the upper cover 2.
[0042] It can be understood that, with such arrangement, the tear head 42 and the tear tail 43 of the tear strip 4 are respectively located on both sides of the flip connection part 5. After the tear strip 4 is completely torn off, only the flip connection part 5 is left between the upper cover 2 and the anti-theft ring 1. During the flipping process of the upper cover 2, the flip connection part 5 needs to be bent and deformed. The angle at which the upper cover 2 is flipped open relative to the bottle mouth 101 matches the bending deformation width of the flip connection part 5. The tear head 42 and the tear tail 43 are both torn toward the upper cover 2 for a distance, so that the width of the flip connection part 5 is longer, thereby ensuring that the upper cover 2 can be flipped smoothly.
[0043] In order to form the easily torn connection groove 41, in this embodiment, reference Figure 5 The cross section of the connecting groove 41 is V-shaped.
[0044] It can be understood that, with such a configuration, the bottom thickness of the connecting groove 41 on the upper cover 2 side and the anti-theft ring 1 side is the thinnest, and the bottom of the V-shaped connecting groove 41 will form a stress weak area. When the tear strip 4 is pulled, the bottom of the connecting groove 41 will be broken first, and the connecting grooves 41 integrally formed on both sides of the tear strip 4 enable the tear strip 4 to be completely torn off from the bottle cap.
[0045] In order to prevent the bottle cap from being stolen, in this embodiment, reference Figure 5 and Figure 6 , the distance between two adjacent protrusions 11 is smaller than the length of the protrusion 11 .
[0046] It can be understood that, with such arrangement, the protrusion 11 is engaged with the first outer step 102 of the bottle mouth 101, and eight protrusions 24 are arranged at equal angles on the inner wall of the anti-theft ring 1. The anti-theft performance can be further improved by the spacing between two protrusions 11 which is smaller than the protrusions' own length. When one position of the anti-theft ring 1 is pried by an external force, in addition to the protrusion 11 on the other side opposite to the pried position being stably engaged with the first outer step 102, there are at least two protrusions 11 engaged with the first outer step 102 within a 90-degree range of the prying, thereby ensuring that the anti-theft ring 1 cannot be easily pried open from the bottle mouth 101, thereby achieving anti-theft.
[0047] In order to facilitate the installation of the bottle cap, in this embodiment, refer to Figure 5 and Figure 6 , the cross section of the protrusion 11 is ear-shaped.
[0048] It can be understood that, with such a configuration, the lower slope of the protrusion 11 is relatively gentle, so that when the bottle cap is pressed onto the bottle, the lower slope of the protrusion 11 can gradually guide the end face of the bottle to extend into the bottle cap, so that the protrusion 11 is clamped on the first outer step 102, and the upper slope of the protrusion 11 is relatively steep. After the bottle cap is pressed, the relatively steep upper slope can abut against the surface of the first outer step 102, so that the protrusion 24 is stably clamped with the first outer step 102.
[0049] In order to smoothly flip the upper cover 2, in this embodiment, refer to Figure 3 An X-shaped groove 51 is formed on the inner wall of the flip connection part 5 . When the flip connection part 5 follows the upper cover 2 to flip relative to the anti-theft ring 1 , an X-shaped fold is formed at the X-shaped groove 51 .
[0050] It can be understood that, with such an arrangement, the center of the X-shaped groove 51 is the flipping center of the flip connection part 5. With the center of the X-shaped groove 51 as the boundary, the groove on the lower side of the X-shaped groove 51 cooperates with the anti-theft ring 1, and the groove on the upper side cooperates with the upper cover 2. The thickness of the inner wall of a rectangular area of the flip connection part 5 centered on the X-shaped groove 51 is reduced. Through the flexibility of the flip connection part 5 itself, the flip connection part 5 is bent and deformed with the X-shaped groove 51 as a crease, so that the upper cover 2 can be flipped smoothly without tearing the flip connection part 5.
[0051] The embodiment of the present application adopts an integrated injection molding structure. The assembly of the bottle cap and the bottle is completed as long as the whole is clamped at the bottle mouth 101 of the bottle. The production process and the assembly process are simple. The anti-theft of the bottle mouth 101 is achieved by a circle of protrusions 11 on the inner wall of the anti-theft ring 1. The upper cover 2 is connected to the anti-theft ring 1 through the flip connection part 5 and the tear strip 4. The tear strip 4 passes through the stress weak area of the connecting groove 41, and a small external force can tear off the tear strip 4, which is convenient for unsealing. After unsealing, the upper cover 2 is flipped and set at the bottle mouth 101 through the flip connection part 5 and the anti-theft ring 1. The flip connection part 5 is bent and deformed by its own flexibility and the X-shaped groove 51, so that the upper cover 2 is smoothly flipped to open the cover, and the sealing ring 21 of the upper cover 2 is interference fit with the inner wall of the bottle mouth 101, so that the upper cover 2 seals the bottle mouth 101, which is beneficial to the preservation and leakage prevention of food.
[0052] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
