Abstract
Abstract An apertured article, for example, a toroidal foam rubber cushion suitable for use in an infant''s head rest or the like, is protected by a cover which includes four sheets of formable material, for example, a textile such as woven cotton fibers, each having a shape conforming to the cross-sectional configuration of the article in a principal plane therethrough, for example, an annulus for a toroidal article. First and second of the sheets are joined at their peripheral edges to define a first enclosure for the article. Third and fourth of the sheets are joined at their peripheral edges to define a second enclosure for both the article and the first enclosure. The two enclosures defined by the joined pairs of sheets are joined serially, completely to enclose the article while leaving the aperture therethrough accessible. The joined sheets form a cover having a unitary structure which can be applied to and removed from the article without the use of buttons, fasteners or the like.
