[0027] like Figures 1 to 3 As shown, this embodiment provides an easy-to-pull sealed bottle cap, comprising a shell 1 and a sealing film 2 sealedly connected to the bottle mouth and arranged on the inner side of the shell 1, at least one set of tearing components 3 is arranged on the shell 1, and the tearing components 3 are also fixedly connected to the upper surface of the sealing film 2, wherein the tearing components 3 can tear the sealing film 2 from the bottle mouth when pulling and tearing the shell 1 along the outer side of the bottle mouth;

[0028] The tearing assembly 3 includes a tearing portion 31 formed integrally with the housing 1 by stamping and a pull ring 32 arranged on the tearing portion 31, and an indentation is prefabricated at the connection between the tearing portion 31 and the housing 1, and the tearing portion 31 is also fixedly connected to the sealing film 2;

[0029] The outer shell 1 includes a surrounding sleeve 11 that fits with the bottle mouth and an annular sleeve 12 that is arranged on the top of the surrounding sleeve 11 and has a circular groove;

[0030] The sealing film 2 includes an annular film 21 surrounding the side wall of the bottle mouth and an upper cover film 22 arranged on the upper side of the annular film 21 and covering the top of the bottle mouth. The inner side of the annular film 21 is provided with a sealing groove 4 that matches the spiral protrusion on the outer side of the bottle mouth.

[0031] A sealing buckle 5 is provided at the bottom of the tearing portion 31, and a fixing groove 6 matching with the sealing buckle 5 is provided on the surface of the upper cover film 22;

[0032] When it is necessary to open the bottle cap, the user only needs to hold the pull ring 32 with his fingers and then pull it toward the outside of the bottle mouth. The pull ring 32 can drive the tearing portion 31 to be lifted and torn off along the indentation on the shell 1. Because the tearing portion 31 is stuck in the fixing groove 6 on the surface of the upper cover film 22 through the sealing buckle 5 at its bottom, the sealing film 2 fixed at its bottom will be torn off from the bottle mouth when the tearing portion 31 is torn off. At this time, the user can easily tear off the entire shell 1 and the sealing film 2 from the bottle mouth through the crack, thereby facilitating the opening of the bottle cap and saving time and manpower. In addition, the sealing groove 4 can improve the sealing between the sealing film 2 and the bottle mouth, preventing the liquid food inside the bottle from flowing out of the bottle mouth.

[0033] The sealing film 2 is made of polyethylene material; since polyethylene has good elasticity, a stable structure and will not migrate, it will fit tightly against the bottle mouth, has good sealing performance, and will not contaminate food.

[0034] Among them, there are two groups of tearing components 3, and the two groups of tearing components 3 are symmetrically arranged on both sides of the shell 1; through the two groups of tearing components 3, cracks can be torn on both sides of the shell 1 and the sealing film 2, further facilitating the user to tear the shell 1 and the sealing film 2 off the bottle mouth.
