Abstract

The sealing ring has a base, with an upper portion composed of two parts. The first part has a horizontal portion extending from the side to the point of connection with the second part, where it merges into a second, rectilinear part sloping upwards at an acute angle from the point of connection. The rectilinear portion is connected to the side by an arcuate portion.
