Screwing and clamping type wine jar sealing cover

Abstract

The invention relates to a screwing and clamping type wine jar sealing cover. A jar cover with a plug is directly connected to a wine jar opening in a screwing manner for sealing. The plug part of the jar cover is of an externally-threaded structure. The inner wall of the wine jar opening is provided with at least one convex point matched with an external thread. Due to the fact that the situation that the jar cover and the jar opening are in hard connection, the convex point is adopted for overcoming the defect that an internal thread cannot be arranged on the inner wall of the jar opening; the structure is simpler; the production technology can also be achieved easily; and a very good sealing effect can be achieved through a sealing ring on the joint of the sealing plug and jar cover.

Description

technical field [0001] The invention relates to a sealing structure of a wine jar, in particular to a screw-type wine jar sealing cover. Background technique [0002] At present, most liquor production enterprises store the brewed liquor, especially the high-quality part, in pottery jars until they are matured, but the mouth of the altar cannot be completely flat due to the production process, leaving a large number of gaps in the mouth of the altar. The liquor in the altar volatilizes, passes through the gaps, and penetrates the white paper, leaving a large amount of alcohol gas in the wine storehouse. [0003] At the same time, considering the small diameter of the mouth of the altar, the process of setting the connecting internal screw on the inner wall of the mouth of the altar is very complicated, and the sealing effect is not good, so the applicant designed a packaging device for the wine jar, such as the one with the application number 2014101948961 An anti-theft dev...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a screw-on type wine jar sealing cover, which is directly screwed on the mouth of the wine jar with a plugged lid for sealing. There is a convex point that cooperates with the external thread. Considering that the altar cover and the mouth of the jar are hard connected, the present invention uses the convex point to solve the defect that the inner wall of the mouth of the wine jar cannot be provided with internal threads. The structure is simpler, and the production process is also easy to realize. The sealing ring at the junction of the sealing plug and the altar cover can play a good sealing effect
