Description

Bottleneck diaphragm structure, diaphragm cover and container Technical Field The application relates to the technical field of beverage containers, in particular to a bottle mouth diaphragm structure, a diaphragm cover and a container. Background The beverage container structure generally comprises a bottle body and a bottle cap, wherein most of the bottle caps are in a threaded connection with the bottle body. For lactobacillus beverage, the sealing of the container bottle mouth adopts the form of diaphragm hot pressing, for example, AD calcium milk, bunge Le, yangshuo and other beverages all adopt the form of diaphragm sealing, the diaphragm cover formed after the diaphragm sealing is difficult to unseal, and the diaphragm needs to be sheared by scissors to achieve the purpose of drinking. Disclosure of utility model In order to facilitate removing the membrane, a first object of the present application is to provide a bottleneck membrane structure. The application provides a bottleneck diaphragm structure which adopts the following technical scheme: a finish film structure comprising: The mouth mold area is used for closing the bottle mouth; a sealing area connected to the outer edge of the neck mold area for sealing connection with the port surface at the outer edge of the bottle mouth, and The enclosing area is connected to the outer edge of the sealing area and is used for being attached to the outer peripheral wall of the bottle mouth; At least two gaps which are distributed at intervals are formed in the circumferential direction of the enclosing area, and a lifting part which can be separated from the outer circumferential wall of the bottle opening is formed between every two adjacent gaps.
