Abstract
Abstract A smoker''s pipe cover includes a bowl cap and skirt formed integrally from rubber or other air-impervious, resilient material. The bowl cap has a width sufficient to span the top of the pipe bowl and is provided with a thickened, stiff central portion opposite the pipe bore for insuring proper location of the cover on the bowl. The skirt resiliently engages the exterior bowl surface, detachably mounting the cover on the pipe The central portion is arranged to project away from the opposite surfaces of the skirt such that the cover may be inverted regardless of which surface of the central portion is placed within the upper open end of a pipe bowl.

A smoker''s pipe cover comprising (a) a bowl cap having a central portion surrounded by a peripheral edge portion, and (b) a peripheral skirt depending from said peripheral edge portion, said cap and skirt being integral with each other and formed from a substantially air-impervious resilient material, said bowl cap being arranged to span the top of a pipe bowl and said skirt extending transversely of said bowl cap and arranged to frictionally engage the exterior pipe bowl surface, said central portion of said bowl cap being thickened relative to said peripheral edge portion to provide a pair of opposed transversely projecting bosses, one of said bosses projecting from one side of said central portion and the other of said bosses projecting from the opposite side of said central portion so that when said pipe cover is positioned on a pipe bowl one of said bosses extends inwardly relative to the pipe bowl and the other of said bosses extends outwardly relative to said pipe bowl, each of said bosses having a peripheral surface inclined away from said peripheral edge portion whereby said boss can engage the inner edge of pipe bowls of varying diameters, said skirt being reversible to opposite sides of said peripheral skirt being sufficiently thin to facilitate said reversing of said skirt.
