Claims

[Claims for Utility Model Registration] 1. The entire container is made of synthetic resin, and the top wall covering the upper part of the mouth of the container and the side wall part covering the sides of the mouth of the container are integrally formed, The cap further includes an inner annular flange that extends downwardly and inwardly from the upper wall portion and an outer annular flange that extends downwardly and outwardly from the upper wall portion with a space between them. The inclination angle of the outer annular flange downward and outward is greater than the inclination angle of the inner annular flange downward and inward from the upper wall, and the boundary between the lower surface of the upper wall and the inclined base of each annular flange is formed as a rounded surface, A cap for vacuum sealing a container, characterized in that the radius of the inner annular flange side is larger than that of the outer annular flange side. 2. The vacuum sealing cap for a container according to claim 1, wherein the outer annular flange is longer than the inner annular flange. 3. The vacuum sealing cap for a container according to claim 1, wherein the inner annular flange is longer than the outer annular flange. 4. The distance between the inner annular flange and the outer annular flange of the upper wall is formed to be smaller than the smallest wall thickness of the container opening, as claimed in claim 1 of the above-mentioned utility model registration claim. Vacuum-sealing cap for the containers listed.
