Container cover

Abstract

The invention relates to a container cover and provides a novel structure. The container cover comprises an outer sleeve barrel and a seal cover. The seal cover is arranged at the top of an inner cavity of the outer sleeve barrel, a side wall and a top wall of the seal cover are connected through a flexible part, an inner wall of the flexible part is connected with a plurality of blocking pieces along a circumferential direction, and a thread part is arranged on the inner side of the side wall of the seal cover. Before the seal cover is packaged on a container, the flexible part is in a free state, and every blocking piece extends downwards along an axial direction; when the seal cover is initially packaged on the container, the flexible part is in an axially downward stretching state and enables the blocking pieces to be inclined inwards in a radial direction, and a top wall of the outer sleeve barrel and the top wall of the seal cover are kept fixed; and when the container is sealed again after opened, the blocking pieces abut against the upper portion of a container opening.

Description

technical field [0001] The invention relates to a lid of a sealed container, in particular to a lid used for holding expensive beverages such as wine and the like. Background technique [0002] In the field of packaging of valuable liquids such as alcohol, in order to enable consumers to distinguish whether the container has been opened, various anti-counterfeiting means are used to design the bottle cap. The outer cylinder of the bottle cap is separated into upper and lower parts, and the set skirt structure is flipped from the original state inside the outer cylinder to the outside of the outer cylinder, so that the skirt cannot be put back when the container is closed again. Between the outer cylinder and the lower outer cylinder, an obvious visual change is formed, as disclosed in Chinese patent ZL02810611.3. [0003] Yet along with the development of science and technology, counterfeit technology is also more and more sophisticated, and the counterfeiter of above-menti...
