  • Patent number: 7124911
    Abstract: The present invention provides a container for dispensing individual paper products that includes a housing, a cover hingedly or removably attached to the housing wherein the cover defines a dispensing opening, a means for elevating paper products, and a plunger disposed in the interior area of the housing. The plunger is urged toward the dispensing opening by the means for elevating paper products. The container may be included in a system for dispensing paper products that further includes a cartridge containing paper products. The cartridge defines a dispensing opening and a second opening wherein the means for elevating paper products extends through the second opening into the interior area of the cartridge to contact the paper products and urge the paper products toward the dispensing opening. The cartridge and container may be configured wherein the second opening is formed by removal of a removable portion during the process of inserting the cartridge into the container.

  • Patent number: 5698291
    Abstract: Disclosed is a process for producing a crimp-bonded fibrous cellulosic laminate. The process includes the steps of: 1) providing at least two superposed plies of a fibrous cellulosic material; 2) passing the superposed plies through a crimp roll arrangement including a rotating crimp element and a rotating anvil element; and 3) applying a pressure load against the rotating elements sufficient to crimp bond the fibrous cellulosic material plies into a laminate. The crimp element has protruding members configured in a discontinuous pattern aligned on an axis that is parallel to the cross-machine direction to provide a substantially continuous uniform area of localized surface contacts between the rotating crimp and anvil elements across the width of the plies. Also disclosed is an overall crimp-bonded fibrous cellulosic laminate and an apparatus for crimp-bonding multiple superposed plies of a fibrous cellulosic material.
