Claims

[Scope of utility model registration request]

A seal ring that is formed at the mouth of the container to protrude in the direction of the axis of the mouth and whose protruding tip forms a sealing surface for heat-sealing the lid member, the seal ring having a flat surface that includes the axis. A trapezoidal section having a cross-sectional shape in which the width of the upper base is the width of the sealing surface and the width of the lower base is larger than the width of the sealing surface, and a ridged part rising almost perpendicularly from the upper base to the sealing surface is integrally formed. A seal ring at the mouth of a container characterized by a connected shape.
