Abstract: A container. The container has a plurality of upstanding sidewalls interconnected by a floor pan. The sidewalls are selectively reinforceable with upstanding struts. The struts are removable from the sidewall and transformable between reinforcing and nonreinforcing positions preferably without separation from the container. The floor pan of the container may also be reinforced. If so, the floor pan support and sidewalls struts may be made of a contiguous articulable, planar reinforcement. The sidewall struts may be articulated about proximal ends juxtaposed with the floor pan. The sidewall struts are particularly useful for collapsible containers.

Abstract: A sleeve is provided for a frusto-conical beverage cup, configured to fit around the outside of the cup, thus protecting the fingers of the user from excessive temperatures in the case of a hot drink, and to provide a measure of insulation for the contents of the cup. The sleeve is an arcuate band of flexible, single-face corrugated material with curved side walls, oppositely extending slots adjacent the ends of the band and tabs lying alongside the slots, the tabs projecting only part-way across the width of the band, to facilitate the setting up of the sleeve.
