With Insertable Or Removble Panel Unit, E.g., "convertible" Patents (Class 450/149)
  • Patent number: 5701608
    Abstract: An undergarment apparatus (20) and method for reducing menstrual cramping includes an elastic panel (30) mounted to at least one of a front portion (24) and a rear portion (25) of an underpant brief (21) in a manner exerting inward pressure across a lower torso region (31) of an individual wearer (23). At least one movable pressure bearing insert (32) is formed for positioning between the elastic panel (30) and the lower torso region (31) at a plurality of positions along the elastic panel (30). The elastic panel (30) cooperates with an apex portion (33) or small area side of the pressure bearing insert (32) to exert substantial localized point pressure on a relatively small area of the torso region (31) for mitigation of menstrual cramping.
