发明名称 CUSHIONED TOILET SEAT
摘要 This invention comprises a cushioned toilet seat in which a foam rubber cushion element is superimposed upon a rigid base member of annular configuration, and a plastic skin is vacuum formed thereabout with lapped over heat-sealed joints at the marginal edges of the base member. Apertures in the bottom of the plastic sole sheet communicate with channels extending through the base member to permit air entrapped within the cushion to be expelled when the skin is compressed against the cushion.
