Document Type and Number:
Japanese Patent JP2530653
Kind Code:
B2
Abstract:
A urine collection receptacle has a body formed by walls sealed along the periphery. First and second sheets form a drape which is situated between the walls. The drape extends across the body below the inlet, with the side edges of the drape sealed along opposing sections of the periphery. The sheets are sealed to each other along spaced vertical lines to define the body of a flap valve. The vertical sealed lines are severed to detach the flap valve body from the remainder of the drape. The sheets may also be sealed along oppositely oriented, downwardly inclined lines to form a funnel to direct liquid from the inlet toward the flap valve. The structure facilitates manufacture because the drape is sealed to the receptacle body in the same automated operation which seals the periphery of the walls.
