ABSTRACT:
A smoker's pipe comprises a bowl portion having a tobacco-receiving cavity below which is formed a transverse, tapering socket. A passageway interconnects the cavity with the socket. A tapering end portion of a stem part is a friction push-fit into the socket whereby the bowl portion can be rotated about the end portion of the stem part. The stem part includes a bore communicating directly with, and forming an extension of, the passageway. A primary reservoir in the lower regions of the bowl portion communicates with the bore and the passageway but is not in the direct path between the bore and the passageway, thereby keeping to a minimum the internal surface area of the pipe between the cavity and the bore. Thus the primary reservoir stores unwanted liquid in the pipe. Rotation of the bowl portion relative to the stem portion seals off the cavity from the reservoir and bore.
