  • Patent number: 5140713
    Abstract: A bath pillow for use as a head rest within a bathtub has an outer casing enclosing a resilient plastic foam filler. The casing includes a front covering and a rear covering secured together at respective peripheral edges corresponding to the peripheral configuration of the pillow. A sheet of film is disposed between the front and rear coverings and secured to the peripheral edges thereof. A resilient suction cup is secured to the sheet of film and projects outwardly from the rear covering so that the film and the front covering provide a water impervious enclosure about the foam filler, and the detaching force is not applied directly to the rear surface but is applied to the film sheet which is aided by the rear covering.
