Document Type and Number:
WIPO Patent Application WO/2016/163712
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a middle- or large-capacity airtight container which enhances sealing between a stopper and a neck part and prevents loosening of the stopper coupled to the neck part, thereby preventing leakage of contents. The present invention provides a middle- or large-sized airtight container comprising a stopper and a bottle. The stopper comprises a skirt part having a first thread formed on the inner surface thereof; a cover part for closing one end of the skirt part; and an annular protrusion part which is protrusively formed on the inner surface of the cover part. The bottle comprises a neck part which has a second thread on the outer surface thereof so as to be screw-coupled to the first thread of the skirt part, and through which contents can pass. When the stopper is coupled to the neck part of the bottle, the annular protrusion part is positioned inside the neck part. Here, a groove is formed on the outer surface of the annular protrusion part that faces the inner surface of the neck part, and the stopper further comprises an O-ring which is disposed in the groove.
