Easily opened crown-shaped bottle cap and manufacturing method thereof

Abstract

The invention discloses an easily opened crown-shaped bottle cap and a manufacturing method thereof. The easily opened crown-shaped bottle cap consists of a bottle cap top and a bottle cap side face, wherein a connecting strip with a handle is extended from the bottom edge of the bottle cap side face; vertical first and second cuts are symmetrically arranged on two sides of the connecting strip of the bottle cap side face respectively; and the first and second cuts are positioned between the bottom edge of the bottle cap side face and the bottle cap top. The bottle cap can be easily and conveniently opened in the way; damage to a bottleneck when the bottle cap is opened is avoided; the recyclability rate of a glass bottle is improved; when the pressure of the sealed glass bottom is overhigh due to external factors, the cuts on the sides of the bottle cap are expanded open and leaks gas, so the danger of bottle burst after the glass bottle is sealed is reduced; the winding and inserting phenomenon appearing between crown-shaped bottle cap in a flow line production process caused by the cuts can be avoided; the quality of the product is guaranteed; and the production efficiency is improved.

Description

technical field [0001] The invention relates to an easy-open crown-shaped bottle cap for glass bottles used for the outer packaging of wine and beverages and a manufacturing method thereof. Background technique [0002] The glass bottle caps that are used to hold alcoholic beverages and beverages in the market all adopt crown-shaped bottle caps, and an opening tool is needed when opening, which brings inconvenience to consumers.

Problems solved by technology

[0002] At present, the glass bottle caps used for wine and beverages on the market all use crown-shaped caps, which require an opening tool when opening, which brings inconvenience to consumers.

In order to solve this problem, people have adopted the method of riveting the pull ring on the bottle cap and having two pre-scoring lines, such as the invention patent of CN1404940A, which discloses a "manufacturing method of easy-open bottle cap". "The disadvantage of this kind of bottle cap is that it is difficult to keep the depth of the notch consistent, it is difficult to ensure the consistency of the packaging quality, and it is difficult to ensure the convenience of opening. With the improvement of packaging grades and the demand for easy opening, other The structure of the crown-shaped bottle cap, but there is always a phenomenon of bottle mouth contusion during the opening process, and there is a danger of bottle explosion after the glass bottle is sealed
