Abstract
A packing member, in either strip or annular form, the member comprising two lip sections adjoined to form a broad planar head surface. Each of the lip sections has a base with an outer lateral surface, and a groove extends along the entire length, or circumference, of the packing member between the bases. At least one of the lip sections includes a laterally outwardly depending sealing projection having a generally laterally outwardly facing side surface and a lower surface. In a relaxed state, the lower surface is disposed generally at an angle to the outer lateral surface of the respective base so as to be non-downwardly inclined from the outer lateral surface. The sealing projection is of such volume and cross-sectional configuration that, upon application of a generally laterally inward force to the side surface, the sealing projection is deformed to form a cavity adjacent its lower surface.
