  • Patent number: 6197010
    Abstract: A low-profile faceplate assembly for a two-piece ostomy appliance, and a method for manufacturing it, are disclosed. The faceplate includes a wafer of an adhesive skin barrier material and a flexible plastic coupling ring (for detachably coupling the faceplate to an ostomy pouch having a mating ring), and is distinguished by the mounting flange of the coupling ring being embedded within the faceplate.
    Type: Grant
    Filed: November 22, 1999
    Date of Patent: March 6, 2001
    Assignee: Hollister Incorporated

  • Patent number: 6106507
    Abstract: A faceplate for an ostomy appliance is disclosed in which a unitary release sheet covers both the bodyside (rear) surface of an adhesive skin barrier layer and the surrounding adhesive surface of an outwardly-projecting porous covering layer. The barrier layer is beveled to a feathered outer edge and the release sheet contacts the adhesive surface of the covering layer immediately adjacent the outer edge of said barrier layer. A continuous in-line method for making such faceplates is disclosed.

  • Patent number: 6093276
    Abstract: A low-profile faceplate assembly for a two-piece ostomy appliance, and a method for manufacturing it, are disclosed. The faceplate includes a wafer of an adhesive skin barrier material and a flexible plastic coupling ring (for detachably coupling the faceplate to an ostomy pouch having a mating ring), and is distinguished by the mounting flange of the coupling ring being embedded within the faceplate. The faceplate is made by a convergence of in-line processes taking place simultaneously with an injection/compression molding operation for the skin barrier wafer as disclosed in U.S. Pat. No. 5,716,475, thereby eliminating or greatly reducing the assembly labor for the various process steps plus the handling, storing and transferring steps commonly associated with the manufacture of ostomy faceplate assemblies.
