    Abstract: In this tubular cup dispenser, resilient cup-engaging fingers are secured to the inner wall of a tubular housing and extend both forwardly toward a front opening and radially inwardly. At the foremost end of each finger is a radially outwardly extending leg. Each leg has a forwardly extending foot which is guided by a radially extending slot in a ring attached to the tubular housing and surrounding the front opening. The inner face of the ring and the legs have interengaging teeth which, when engaged, prevent radial movement of the cup-engaging fingers. Disengagement of the teeth and adjustment of the fingers is accomplished by manipulation of the forwardly extending feet.

  • Patent number: 4416392
    Abstract: A dispensing device for use in dispensing sheets of material coated along one edge with a narrow band of readily releasable pressure-sensitive adhesive. The dispenser comprises a container having a pair of sidewalls connected by a top wall which is formed with a transversely extending rectangular opening extending in the direction parallel to the side walls. The sheets are stacked within the dispenser such that upon removing the uppermost sheet in the stack the adhesive coating along one edge of the sheet adhered to the edge of the next sheet in the stack will cause the next sheet in the stack to be withdrawn at that free edge through the dispensing opening upon withdrawal of the uppermost sheet.

  • Patent number: 4343415
    Abstract: A napkin dispenser designed primarily for disposition on a restaurant table or counter and normally housing a stack of paper napkins. The dispenser is in the form of a parallelopiped with a top access opening for loading and removing napkins. The opening is generally rectangular or may taper slightly from one end ot the other. An important feature is that the edges of the opening extend outwardly, providing a relatively narrow peripheral arcuate flange or lip around the opening, the effect of which is lead a napkin gently outwardly without likelihood of damage to the exiting napkin. My improved construction more or less insures extraction of a single napkin at a time, inhibiting vandalism and results in substantial economy of construction and operation. Another improved feature is a novel follower arrangement including a coil spring for urging the napkins toward the egress opening and designed to insure that the coil spring is maintained in proper axial alignment for maximum efficiency.

  • Patent number: 4329001
    Abstract: A dispenser for folded paper napkins including an enclosed cabinet having an opening in the front thereof through which napkins may be removed individually. A pair of V-shaped guides are mounted on inside surfaces of opposite sides of the cabinet. A drawer for holding a supply of folded napkins has a pair of V-shaped ribs formed along opposite sides which slidably engage the guides to movably support the drawer within the cabinet. A carriage assembly including a pressure plate for engaging the rear of the napkin supply in the drawer has a pair of V-shaped slides affixed to opposite sides. The sides slidably engage the ribs to movably support the carriage assembly in the drawer. A pair of constant force springs are affixed to the cabinet and engage the rear of the pressure plate to urge the plate and carriage assembly forwardly of the drawer against the rear of the napkin supply to facilitate individual removal of the napkins through the cabinet opening.

  • Patent number: 4311252
    Abstract: A large capacity elevator-type napkin dispenser comprising an elongated supporting structure or cage composed of a series of spaced rod-like vertical supports. A stack of folded napkins is supported on a pressure plate that is mounted on a carriage adapted to slide vertically within the cage. The pressure plate is supported from the carriage by a plurality of compression springs which enable the pressure plate to float and accommodate the varying thickness of the stack of folded napkins. A cover is mounted on the upper end of the cage and has an opening through which the napkins are dispensed. The pressure plate and stack of napkins are urged upwardly toward the undersurface of the cover by a biasing mechanism that includes a pair of extension springs. The springs have a varying spring rate so that the force of the springs will be greatest when the pressure plate is fully loaded with napkins.

  • Patent number: 4243153
    Abstract: A dispenser assembly for disposable plastic bowls is disclosed which includes a rectangular housing, open at the top, and a housing cover disposed thereover and defining a circular opening in the top. A slotted, flat, rectangular article supporting plate rides along raised, elongated and vertically extending rails formed on opposite inside walls of the housing which project into the slots. A coiled spring disposed in the housing supports the plate and extends around a raised circular wall formed on the bottom of the plate. A series of three elongated elements or nibs project downwardly from a ceiling of the housing cover around the circular opening and project inwardly of the opening a slight distance sufficient to interfere with and catch against the rolled rims of bowls stacked on the plate and projecting upward through the opening in the housing cover. A companion lid dispenser can be incorporated into the housing for convenience and efficient utilization of space.

  • Patent number: 4199076
    Abstract: A dispenser of cups. A main body includes a cup cavity having a slidable plate mounted therein for receiving a stack of cups. A helical spring urges the plate toward the cavity opening to allow for the removal of one cup at a time from the dispenser main body. The spring is yieldable to allow a new stack of cups to be inserted into the cup cavity. A plurality of ribs within the cavity provide guide means upon which the plate moves to and from the cavity opening. The ribs have enlarged ends which project into the cavity preventing the plate from moving through the opening and insuring that only a cup at a time is removed from the dispenser. A centering plateau on the plate locates the stack of cups.

  • Patent number: 4094442
    Abstract: A napkin dispenser for disposition on a restaurant table or counter and normally housing a stack of paper napkins. The dispenser is in the form of a parallelepiped with a top access opening for loading and removing napkins. Said opening is generally rectangular except for a concavely arcuate edge on one side from which napkins are normally extracted. Two opposed sides of said opening normal to the arcuate edge are provided with a pair of relatively narrow spring biased leaves resiliently extendable into the container to facilitate loading, the free edges of said leaves being longitudinally gently oblique and widening toward the aforesaid arcuate edge. Each of said leaves has a longitudinal outwardly turned lip and the exposed corners of the leaves are rounded. All of said features contribute toward convenient extraction of a napkin without damage.
