Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to an anti-theft bottle cap. Background Art

[0002] Plastic bottle caps with anti-theft rings are widely used in the reagent industry because of their strong sealing, good leak-proof and anti-theft performance, safe and convenient use, effective protection of the liquid in the bottle from external contamination, and low production cost. The characteristics of this bottle cap are: a corresponding gasket is placed on the inner wall of the top of the bottle cap or a leak-proof ring is provided, the lower end of the bottle cap is connected to an anti-theft ring through a connecting bridge, and a number of anti-detachment teeth are evenly distributed on the inner side of the anti-theft ring. When the bottle cap is opened, a reaction force is generated by the fixation of the anti-detachment teeth and the bottle mouth, so that the bottle cap and the anti-theft ring are completely separated. After the separation, the bottle cap is opened, and the anti-theft ring falls off and remains at the bottle mouth. At present, the anti-theft bottle caps on the market are all integrally molded, which will cause defects such as appearance deformation and shrinkage during injection molding, thereby affecting its use and may not be assembled on the bottle.

[0019] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0020] Reference Figures 1 to 4A theft-proof bottle cap comprises an upper cover 1 and a ring cover 2, wherein the upper cover 1 comprises an upper cover body 11 and a connecting portion 12 arranged at the bottom of the upper cover body 11, wherein the inner side of the upper cover body 11 is provided with an internal thread which can be connected with the bottle mouth thread, the ring cover 2 comprises a ring cover body 21 and an anti-theft ring 22 arranged at the inner side of the ring cover body 21, and a clamping mechanism 3 which can fix the upper cover 1 and the ring cover 2 is provided between the connecting portion 12 and the ring cover body 21, and a connecting rib 23 which can connect the ring cover body 21 and the anti-theft ring 22 is provided between the ring cover body 21 and the anti-theft ring 22, and a plurality of inwardly inclined limiting tension wings 24 are provided on the inner side of the anti-theft ring 22, so that the anti-theft bottle cap can be limited after being put on the bottle. In this way, the anti-theft ring 22 is arranged on the ring cover body 21 to form the ring cover 2, and then the upper cover 1 and the ring cover 2 are fixedly connected by the clamping mechanism 3, thereby avoiding defects such as appearance deformation and shrinkage of the entire anti-theft bottle cap during injection molding.

[0021] Specifically, the clamping mechanism 3 includes a limiting groove 31 disposed on the outside of the connecting portion 12, and a buckle 32 disposed on the inside of the ring cover body 21 and engaged with the limiting groove 31. Furthermore, the limiting groove 31 is an open groove, and a limiting boss 33 is provided on the bottom end of the upper cover body 11 that can abut against the upper surface of the ring cover body 21, so that the buckle 32 is clamped in the limiting groove 31 to lock the upper cover 1 and the ring cover 2, and they cannot be opened.

[0022] In this solution, a guiding inclined surface is provided on the outer side of the connecting portion 12 and below the limiting groove 31, and a guiding inclined surface is provided on the inner side of the buckle 32 and at its upper end, and a gap is left between the connecting portion 12 and the anti-theft ring 22. In this way, the buckle 32 on the anti-theft ring 22 is conveniently inserted into the limiting groove 31 of the connecting portion 12 by the cooperation of the two guiding inclined surfaces.

[0023] In this solution, the cross-sectional area of ​​the connecting rib 23 gradually decreases from the ring cover 21 side to the anti-theft ring 22 side. Preferably, the connecting rib 23 may be in a triangular shape so that the user does not need to use too much force to twist it off. Furthermore, the connection points of the connecting rib 23 and the anti-theft ring 22 are both set between two adjacent limiting tension wings 24, so that the tension on the connecting rib 23 is more uniform.

[0024] In this solution, the angle between the limiting tension wing 24 and the anti-theft ring 22 is 45°.

[0025] In this solution, an undercut 13 for fixing a gasket is provided on the inner side of the upper cover body 11, thereby ensuring the sealing between the anti-theft bottle cap and the bottle mouth.

[0026] In this solution, the outer side of the upper cover body 11 is provided with anti-slip grooves 14 to facilitate users to twist the anti-theft bottle cap. The anti-slip grooves 14 can be set in the arc-shaped grooves on the outer side of the upper cover body 11.

[0027] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
