Abstract
Abstract An absorbent underpad for hospital patients comprising a liquid permeable upper sheet, a body of liquid absorbent material, an impermeable backing sheet and pressure activated releasable adhesive areas located adjacent corners of the backing to hold the underpad in place under the patient, the same adhesive areas serving, when the used underpad is folded in a specified manner, to hold the pad closed and prevent spillage of the contents pending disposal.

A substantially rectangular absorbent underpad comprising a body of liquid absorbent material, a backing sheet of liquid impermeable material, pressure actuated adhesive areas located adjacent each corner of said backing sheet and being adapted to engage a bed sheet and to be cleanly released from said bed sheet without leaving a residue, the underpad being provided with two parallel fold lines parallel to and spaced from two opposite edges and with two parallel fold lines perpendicular to said first mentioned lines and spaced from the other two opposite edges, whereby the adhesive areas can engage a bed sheet and hold the underpad against movement while in use and can engage other parts of the underpad when the latter is folded sequentially along said fold lines after use.
