  • Patent number: 8186541
    Abstract: A dispenser for dispensing interfolded disposable sheets is disclosed. The dispenser includes a removable panel that is attached to the first sheet in the stack contained in the container. When the removable panel is pulled off the container, the first sheet in the stack is partially or completely withdrawn from the container. The removable panel may be adhered to the first sheet using an adhesive material. The adhesive material may be contained in a recess formed in the removable panel. The recess is designed to protect the adhesive material during manufacture of the product and/or to prevent the adhesive material to adhering to other portions of the product. In one embodiment, after the stack of sheets are loaded into the dispenser, the recess is inverted forming a protrusion that contacts the first sheet in the stack and forms a bond between the removable panel and the first sheet.

  • Patent number: 6378726
    Abstract: An interfolded paper napkin dispensing system composed of: (a) an outer housing defining an interior space; (b) stacking means mounted within the outer housing for holding a stack of paper napkins within the interior space; and (c) a dispensing face defined in the outer housing proximate to an end of the stacking means. The dispensing face has a central portion projecting out from the dispenser and a dispensing throat located in the central portion. The dispensing throat is composed of a slot portion having a length sufficient to permit a paper napkin to be pulled through by a user, but a relatively narrow width that prevents more than a few napkins from being pulled through the throat at one time. The dispensing throat further includes a finger access portion to help a user grip and pull a paper napkin through the dispensing slot despite the relatively narrow width of the dispensing slot.

  • Patent number: 6315155
    Abstract: The device for dispensing multi-fold paper towels has a housing for holding a generally vertical stack of the paper towels and including a lower portion through which individual towels can be dispensed from the stack. The lower portion includes an elongated opening through which a fold of the bottommost towel can extend and be accessible for a user to grab and pull the bottommost towel from the stack. One side portion of the towels rest on a plurality of laterally spaced ribs or ramps located in the vicinity of the front edge of the opening and inclined at an angle upwardly and forwardly relative to the front edge. These ribs or ramps effectively transfer a portion of the pressure applied by the stack on the bottommost towel toward the rear, thereby reducing the force required to pull the bottommost towel from the stack. The opening preferably is shaped to cause the fold of the bottommost towel to assume a C-like shape and thereby reduce the amount of the fold readily accessible to a user.
