Abstract: A collapsible cup has a tubular body having an upper end and a lower end, centered on an axis, and formed with a plurality of helicoidal ridge formations spaced angularly around the tubular body and each extending between the ends of the body. A floor of greater rigidity than the body closes the lower end of the body. A ring reinforces the upper end of the body. The body and ridges are formed of an elastically deformable synthetic resin such opposite angular twisting of the upper and lower ends axially compresses together the upper and lower ends and moves upper end down close to the lower end.

Abstract: An asymmetrical umbrella includes a structure formed by a single frame member that is attached at its first and second ends to a handle and also attached to the handle at a third position along the frame member between the ends of the frame member such that the frame member passes through the handle at the third position. A sleeve collects two portions of the frame member together at a position opposite a periphery of the umbrella from the handle. A canopy is attached to the frame member. The umbrella is collapsible into a generally planar shape that is easily transportable.
