<p>A drinking vessel comprises a first vessel member adapted to hold a liquid and a second vessel member associated with, but separated from, the first vessel member to form a barrier against the formation of condensation on the exterior surface of the second vessel member when a cold liquid is contained in the first vessel member. In one embodiment, the first vessel member comprises a removable insert which conforms generally to the configuration of the second vessel member to form a double-walled drinking vessel. Advantageously, a sanitary lip extends downwardly from the top edge of the insert and is proportioned and oriented to prevent a person's lip from contacting the second vessel member when the person takes a drink. Also advantageously, the drinking vessel includes ribs or serrations, or, preferably, a plurality of protuberances and engagement ridges, ridge segments or recesses associated between the insert and the second vessel member to provide a secure friction fit therebetween yet permit removal of the insert for disposal and subsequent replacement. In another embodiment, the first vessel member comprises a bowl member for holding a liquid and the second vessel member is a hollow stem member supporting the bowl from its base. A collar-like ridge is formed generally at the junction of the stem for collecting any condensation and directing it into the stem. The structure may be formed in two-piece structure or an essentially unitary structure. The structure may, however, include a detachable stem base portion or a stopper-plugged hole in the stem base to facilitate removal of the accumulated moisture.</p> |
