  • SYSTEM FOR APPLYING ABSORBENT MATERIAL TO A SUBSTRATE
    Publication number: 20080276862
    Abstract: A method and system for applying an adhesive/superabsorbent mixture to a substrate, the method and system being adapted for heating an adhesive and superabsorbent polymer mixture to a first temperature at a first pressure, the first temperature being less than the boiling temperature of said mixture at the first pressure; heating the mixture through a heat exchanger at a second pressure, the second pressure being higher than the first pressure, the heat exchanger being adapted to raise the temperature of the mixture to a second temperature that is higher than the first temperature; and selectively applying the mixture to a substrate.
    Type: Application
    Filed: July 17, 2008

  • Environmentally friendly catamenial tampon assembly and method of construction
    Patent number: 5823988
    Abstract: An environmentally-friendly tampon assembly of the type which includes an inner sleeve, an outer sleeve and an absorbent pledget has inner and outer sleeves which are fabricated from a biodegradable, flushable material such as paper. The outer sleeve has an inwardly extending tang for preventing movement of the pledget during retraction of the inner sleeve. The tang is also formed of biodegradable material, and may be formed of material which is from the same blank out of which the outer sleeve was formed. Six different methods of forming the outer sleeve and tang are disclosed.
    Type: Grant
    Filed: April 27, 1995
    Date of Patent: October 20, 1998
    Assignee: McNeil-PPC, Inc.
    Inventors: John Orenga, Edwin H. Sailer
