  • Patent number: 5558659
    Abstract: Absorbent articles of the present invention are specifically adapted for the adult male anatomy. The articles include a moisture barrier having a length measured between front and back ends of less than about 46 centimeters. A liner is bonded to the moisture barrier sandwiching an absorbent assembly therebetween. The moisture barrier is gathered along each of its side edges between forward and rearward terminal points. The forward terminal points are spaced from the front end of the moisture barrier by at least about 7 centimeters, and the rearward terminal points spaced from the back end of the moisture barrier by less than about 5 centimeters. Elasticized containment flaps disposed on the liner extend longitudinally toward the front end to a position at least about 16 centimeters from the back end of the moisture barrier. The moisture barrier is also gathered along its back end.

  • Patent number: 4772280
    Abstract: The invention is generally accomplished by providing an absorbent pouch for the male genitalia that has a generally triangular opening wherein one side of the triangle is adapted to be worn flat against the upper genital region and the other two portions of the triangular opening extend into the crotch and meet behind the scrotum. The pouch extending downward from the triangular opening has sufficient capacity to comfortably contain the male genitalia, and the opening at the top is sufficient to allow air circulation. The allowance for air circulation decreases skin problems.

  • Patent number: 4675012
    Abstract: The invention is generally accomplished by providing an absorbent pouch for the male genitalia that has a generally triangular opening wherein one side of the triangle is adapted to be worn flat against the upper genital region and the other two portions of the triangular opening extend into the crotch and meet behind the scrotum. The pouch extending downward from the triangular opening has sufficient capacity to comfortably contain the male genitalia, and the opening at the top is sufficient to allow air circulation. The allowance for air circulation decreases skin problems. The method for forming the device consists of folding a retangular sheet of composite material on a first fold line that is offset from the middle of the sheet. Next, the points forming the outer ends of the first fold line are folded toward each other so that they are adjacent. The newly formed edges are then folded inwardly toward each other a predetermined distance so as to form the generally triangular opening.
