Abstract:

A sealing groove cover for a cylindrical fluid container includes a circular body, a circular outer sealing member, a circular inner sealing member and a circular male element. The outer sealing member is coupled to the circular body along its outer perimeter edge and snugly contacts the outer surface of the container wall. The circular inner sealing member is coupled to the circular body along its inner perimeter edge and is dimensioned to snugly contact the inner perimeter of a female groove which forms a part of the cylindrical container and is dimensioned to receive and seal with a removable lid. The circular male element of the sealing groove cover is located at a radial distance between the inner and outer sealing members and is aligned with the female groove of the container to form an interference fit between the sealing groove cover and the container female groove. The sealing groove cover prevents contaminating fluids or particulate matter from entering the female groove of the container when the lid is removed from the container.
