  • Patent number: 4538312
    Abstract: There is disclosed is a reversible fitted playpen pad cover including an upper panel having a rectangular area which is the same as the area of the floor of the playpen; a lower panel having the same area and shape as the upper panel in which the lower panel is secured to the upper panel along three of four mutual edges of the panels. This arrangement leaves an unclosed edge between the upper and lower panels and, thus, defines a flexible closure therebetween. There is also provided a rectangular lip panel which integrally depends from the upper panel along the unclosed edge of the upper panel. The lip panel is folded into the volume of the closure between the upper and lower panels and, along its opposite left and right edges that extend from the line of dependency with said upper panel, is secured between the upper and lower panels. The width of said lip panel extends over about one-third of the width of the entire playpen pad cover.
