Abstract
A covered reservoir is disclosed comprising a reservoir body, a holder for the body, a cover, a retainer for the cover, and a seal fitted onto the cover to seal off leak paths between the cover and the reservoir body. The cover is constructed to raise the seal into a frusto-conical position, preferably via a frusto-conical surface on which the seal, which is a flexible annular ring, is seated.
