Abstract: A mixing assembly includes a drum including a side wall, a top portion, and a bottom portion, in which the top portion includes a first opening for filling a substance into the drum, a second opening for mixing the substance in the drum, and a third opening for extracting the substance from the drum; and a mixer releasably disposed in the drum, including a head releasably attached to the second opening for mixing, in which the head includes a housing including an internal hollow region extending along the central axis of the head, and external threads configured to be attached to the second opening for mixing by thread engagement, a shaft disposed in the hollow region, and an impeller assembly disposed at a bottom end of the shaft for stirring the substance in the drum.

Abstract: A blow molded container has a planar pinched section formed between and connecting a top wall, a neck and a front handle end of the container with an anti-glug vent tube formed in the planar pinched section so as to extend through the pinched section and spaced by parts of the planar pinched section away from the neck, from the front handle end and from the top wall. The vent tube is substantially horizontal at the neck breaking through a vertical wall of the neck and has the other end breaking out through the top wall at the bottom of the downwardly extending section between the neck and the front handle end.

Abstract: A container primarily for hot (or cold) beverages such as gourmet coffee has an outer shell formed of a stiff sheet material having heat insulating properties such as cardboard which can be erected from a flat storage condition to enclose an inner lining member for containing the liquid. The inner liner is blow molded from a plastics material to form an integral structure including a neck and a handle projecting through openings in the shell so as to be exposed on an exterior of the container for manual transportation and lifting of the container. The use of a blow molded integral liner allows the handle to be integral with the liner and relatively stiff as a tubular member parallel to an inclined upper surface of the liner. An optional folded leg can be provided to allow the liner to be drained through an optional spigot on the neck. An optional accessory box can be slung on a flap engaged around the neck.
