ABSTRACT:
A vacuum bottle wherein the housing of the insulating jacket has a top section with a circular opening for the extension of a cover which overlies the opening and can be rotated to move one of two apertures in a downwardly extending skirt of the extension into register with a passage at the inlet end of a spout. The cover is separably coupled to the top section of the housing by a bayonet mount which causes the cover to rise during rotation to a pouring position and to descend during rotation to a sealing position. The jacket confines a receptacle for a hot or cold beverage which can be dispensed by way of the spout in the pouring position of the cover.
