Peel-off milk bottle cap

Abstract

The invention provides a peel-off milk bottle cap. The peel-off milk bottle cap includes a cap body and a tear and pull buckle, the peel-off milk bottle cap is characterized in that a convex ring is arranged in the middle of the inner wall of the cap body, the cap body at the top of the convex ring is provided with a tear and pull concave mark, the tear and pull buckle is arranged at one end of the tear and pull concave mark, and is arranged on the edge position of the upper surface of the cap body, the inner surface of the top of the cap body is provided with a fixed ring, the inner surface,near the fixed ring, of the top of the cap body is provided with a sealing ring, and the sealing ring is of a conical structure with narrow upper end and wide lower end. The peel-off milk bottle cap is convenient to use, the structure is simple, the cap is quickly and efficiently opened, and the peel-off milk bottle cap can be reused.

Description

technical field [0001] The invention relates to the technical field of bottle caps, in particular to a tear-off milk bottle cap. Background technique [0002] In the dairy industry, glass milk bottles are widely used as storage containers for milk. This type of glass milk bottle has the advantages of being beautiful, clean and convenient to eat, and has been widely used. However, after the existing milk bottle is opened, the milk bottle If the mouth is exposed to the air, bacteria (such as sedimentation bacteria and planktonic bacteria in the air) will invade the milk bottle and contaminate the milk. [0003] At present, the bottle caps of commercially available milk are screw-on and loose-threaded, reversible, and tear-off. One of the easy-open bottle caps such as Figure 4 The cover body, separation part, and tearing dent are shown in the figure. The separation part is designed at the edge of the cover body. There are several point-shaped fixed connections between the sep...

Problems solved by technology

One of the easy-open bottle caps such as Figure 4 The cover body, separation part, and tearing dent are shown in the figure. The separation part is designed at the edge of the cover body. There are several point-shaped fixed connections between the separation part and the cover body, which increases the difficulty of mold design, and in the capping process It will cause the deformation of the separation part or even destroy the cover

Another easy-to-tear bottle cap such as Figure 5 The cover body, tearing part, and tearing dent shown in the mold will cause a lack of material in the tearing part due to the temperature difference during the mold manufacturing process, and the tearing part will be pressed together in the milk bottle capping process. Inside the cover, making tearing difficult
