Abstract

The present invention provides an apparatus for dispensing rolled sheet material, the apparatus including a housing defining an interior adapted to contain rolled sheet material and a dispensing opening for allowing sheet material to be dispensed from the interior of the housing. The apparatus further includes a nip within the housing such as, for example, may be formed by first and second rollers. In addition, the apparatus includes a mobile roll support system adapted to support a roll of sheet material within the housing wherein the roll of sheet material rotates to dispense sheet material and further wherein the mobile roll support system and the roll of sheet material move toward the nip as sheet material is dispensed.

Claims

1. An apparatus for dispensing rolled sheet material comprising:

a housing defining an interior adapted to contain rolled sheet material and a dispensing opening for allowing sheet material to be dispensed from the interior of the the first and second housing sections each having a peripheral edge, housing, the housing comprising a first housing section and a second housing section, the first housing section being at least partially removably attached to the second housing section, wherein at least one slot is defined within the side of the housing and defined between the peripheral edges of the first and second housing sections;

a nip within the housing; and

a mobile roll support system adapted to support a roll of sheet material within the housing wherein the roll of sheet material rotates to dispense sheet material, further wherein the slot engages the mobile roll support system, and further wherein the mobile roll support system and the roll of sheet material move toward the nip as sheet material is dispensed.

2. The apparatus of claim 1 further comprising first and second slots, each slot engaging the mobile roll support system wherein the mobile roll support system travels within the slots.

3. The apparatus of claim 2 wherein the first slot is parallel to the second slot.

4. The apparatus of claim 1 wherein the first housing section is pivotably attached to the second housing section.

5. The apparatus of claim 1 wherein at least one slot is angled downwardly to allow the mobile roll support system to move toward the nip as the sheet material is dispensed and the diameter of the roll of sheet material decreases.

6. The apparatus of claim 1 wherein the mobile roll support system comprises a dispensing roller having first and second ends, each end slideably engaging a slot.

7. The apparatus of claim 6 wherein the roll of sheet material defines a central core, and wherein the dispensing roller supports the roll of sheet material from within the central core.

8. The apparatus of claim 1 wherein the mobile roll support system comprises at least two mobile supports, each support slideably engaging a track.

12. The apparatus of claim 8 wherein the roll of sheet material is careless.

13. The apparatus of claim 1 wherein the roll of sheet material comprises inner and outer layers of sheet material, the layers of sheet material comprising a plurality of offset zones of weakness that extend substantially across the width of the sheet material.

14. The apparatus of claim 1 wherein the nip comprises at least one roller.

15. The apparatus of claim 1 wherein the nip is pressurized.

16. The apparatus of claim 14 wherein the nip is pressurized by at least one spring.

17. The apparatus of claim 16, wherein the roll of sheet material supported by the mobile roll support system rests against one of the nip rollers, and wherein the path of the sheet material extends through the nip and through the dispensing opening.

18. The apparatus of claim 1 further comprising a sheet material dispensing surface proximate the dispensing opening, the sheet material dispensing surface comprising at least one protrusion.

19. The apparatus of claim 18 wherein the sheet material dispensing surface comprises a fixed member located between the nip and the dispensing opening.

20. The apparatus of claim 19 wherein the fixed member is positioned between the nip and the dispensing opening to allow sheet material to travel along a circuitous path.

21. The apparatus of claim 18 wherein the sheet material dispensing surface is at least partially concave in shape.

22. The apparatus of claim 18 wherein the sheet material dispensing surface is at least partially convex in shape.

23. The apparatus of claim 18 wherein the sheet material dispensing surface comprises at least one concave portion.

24. The apparatus of claim 23 wherein the sheet material dispensing surface comprises at least one flat portion.

25. The apparatus of claim 18 wherein the sheet material dispensing surface comprises at least one convex portion.

26. The apparatus of claim 18 wherein the sheet material dispensing surface at least partially defines the dispensing opening.

27. The apparatus of claim 18 wherein the sheet material dispensing surface at least partially extends into the path between the nip and the dispensing opening.

28. The apparatus of claim 18 further comprising a roll of sheet material having a plurality of zones of weakness that substantially extend across the width of the sheet material, wherein the sheet material is dispensed along a path that extends from the roll of sheet material, through the nip, across the sheet material dispensing surface, and through the dispensing opening.

29. The apparatus of claim 28 wherein said protrusion concentrates force on the portion of the sheet material that contacts the protrusion when the sheet material is pulled across the sheet material dispensing surface and through the dispensing opening.

30. The apparatus of claim 28 wherein the rolled sheet material comprises inner and outer layers of sheet material, the layers of sheet material comprising a plurality of offset zones of weakness that substantially extend across the width of the sheet material.

9. The apparatus wherein at least one of the mobile supports comprises an engaging member attached to at least one of the supports, the engaging member adapted to engage one side of the roll of sheet material.

10. The apparatus of claim 9 wherein at least one engaging member is adapted to extend into the interior of the rolled sheet material.

11. The apparatus of claim 9 wherein the engaging member further comprises a chamfered surface.
