  • 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: 6352172
    Abstract: A folded web product dispensing system includes an outer housing that defines an interior space. A dispensing face is defined in the outer housing proximate to an end of a stacking means. The dispensing face has a central portion and a dispensing throat located in the central portion. The stacking means are mounted within the outer housing for holding a stack of folded web product within the interior space and have a staging area proximate to the dispensing throat including at least two curved bumpers. These curved bumpers are oriented so as to be parallel to the path of travel of the folded webs as they approach the dispensing throat. A number of ribs may be defined on the bumpers for temporarily arresting movement of the folded webs as they approach the dispensing throat. The folded web product may be a stack of paper napkins.

  • Patent number: 6286713
    Abstract: A dispensing system for individual folded webs having an area of non-uniform thickness across the length of the web is composed of several components. An outer housing defines an interior space in which stacking means for holding a stack of individual folded webs are mounted. A dispensing face is 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 in the form of a first surface and a second surface joined at an obtuse angle and a dispensing throat located in the central portion at about the intersection of the first and second surfaces. The dispensing system also includes a stack of individual folded webs having an area of non-uniform thickness across the length of the web aligned so that an area of greatest thickness extends across the width of the dispensing throat.

  • Patent number: 5716691
    Abstract: A dispensable, folded absorbent web product composed of: a first, central panel; a second panel, unitary with said first panel and folded over a first side of said first panel; a third panel, unitary with the first panel, and folded over a second side of the first panel; a fourth panel, unitary with the second panel, and folded so as to be positioned between the first and second panels; and a fifth panel, unitary with the third panel, and folded so as to be positioned between the first and third panels, such that a portion of the third panel and fifth panel overlap a portion of the second panel and fourth panel generating an area of non-uniform thickness across the length of the product which provides for easier, more reliable dispensing.
