Description
Technical Field
The invention relates to the technical field of bottle caps, in particular to a tear-off type milk bottle cap.
Background
In the dairy industry, glass milk bottles are widely used as milk storage containers, which have the advantages of beauty, cleanness and convenience in eating, and are widely used, but after the conventional milk bottles are opened, the bottle openings of the milk bottles are exposed to the air, so that bacteria (such as deposited bacteria and planktonic bacteria in the air) can invade the milk bottles to pollute the milk.
Currently, commercially available milk caps are either screw-on, screw-off, flip-top, or tear-off. One of the bottle caps easy to pull open is composed of a cap body, a separating part and a tearing dent as shown in fig. 4, wherein the separating part is designed at the edge of the cap body, a plurality of punctiform fixed connections are arranged between the separating part and the cap body, the design difficulty of a mold is increased, and the separating part can be deformed or even the cap body is damaged in the capping process. Another easily torn bottle cap is composed of a cap body, a tearing part and a tearing dent as shown in fig. 5, wherein the tearing part is lack of material due to the temperature difference in the manufacturing process of the mold, and the tearing part is pressed inside the cap body in the process of pressing the milk bottle cap, which causes difficulty in tearing.
Disclosure of Invention
The invention aims to provide a tear-off type milk bottle cap, wherein a tear-off buckle is designed on the edge of the top of a cap body through the design of a die, the design reduces the flow resistance of polyethylene in the die, reduces the defective rate, is convenient to use, has a simple structure, can be used for quickly and effectively opening the cap, and can be used again.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a tear formula milk bottle lid, includes the lid, tears and draws knot, its characterized in that: the lid inner wall middle part is provided with the bulge loop, and the lid on bulge loop upper portion is provided with tears and draws the indenture, tears to draw indenture one end to be provided with to tear and draws the knot, tears to draw to detain and sets up at lid upper surface border position, and lid top internal surface is provided with solid fixed ring, and the lid top internal surface that is close to solid fixed ring is provided with the sealing ring, and the sealing ring is the wide taper structure of the narrow lower extreme in.
As a further improvement of the invention, the convex ring is arranged in a subsection mode.
As a further improvement of the invention, the tearing buckle is in a sheet shape and can be arranged into various shapes according to requirements.
As a further development of the invention, the tear notch takes up half of the circumference of the lid body.
The milk bottle cap has the beneficial effects that the tearing buckle and the cap body are integrally designed, the redundant protruding part is arranged in the tearing buckle, the tearing convenience is effectively improved, a consumer can conveniently pull the tearing buckle, the tearing buckle is not easy to slip, the situation that the tearing part is broken can not happen when the cap is torn, the sealing ring and the fixing ring are mutually matched, the milk bottle cap is effectively clamped and fixed, and the sealing performance of the bottle cap is improved.
