Abstract: A disposable umbrella is formed from a single sheet of corrugated material and has a first fold line dividing the sheet into two essentially imperforate panels and forming a peaked-roof shape, with each of the panels having a handle-forming foldout tongue formed along second fold lines disposed perpendicular to the first fold line.

Abstract: A disposable umbrella and the method of manufacture. The umbrella 100 has two parts: a flexible water impermeable canopy (102) and a rectangular rigid frame (104). Pocket (126, 128) are formed in two parallel sides of the canopy. The frame has outer dimensions substantially matching the outer dimensions of the canopy. A center fold line (138) in the frame defines two equal side panels (140, 142) and allows the side panels to fold together into a closed position. The canopy is fitted on the top of the frame by bending the side panels opposite the closed position until the frame sides (134, 136) slip into the canopy pockets. The panels are then returned to the closed position. Handles (156, 158) cut in the side panels fold down for use and position the umbrella in a peak-roof shape when aligned and held by one hand.
