Abstract

A dispenser for dispensing at least one web from a stack of web material is disclosed. The dispenser includes a housing arranged to hold a stack of web material. A web path extends in an interior of the housing in a first direction in a first portion of the housing and in a second direction in a second portion of the housing. The housing includes an access opening providing access to the interior of the housing. The web path is accessible along a third direction, in both the first and second portions of the housing, via the access opening.

First claim

The invention claimed is:

1. A dispenser for dispensing at least one web from a stack of web material, the dispenser comprising:
a housing arranged to hold a stack of web material, wherein a web path extends in an interior of the housing from a stack position to a dispensing opening of the dispenser, the web path extending in a first direction in a first portion of the housing and in a second direction in a second portion of the housing, the first and second directions being directed in substantially opposite directions, and
wherein the housing comprises:
an access opening in a first side portion of the housing, the access opening providing access to the interior of the housing,

wherein the web path is accessible along a third direction, in both the first and second portions of the housing, via the access opening.

2. The dispenser according to claim 1 , wherein the third direction is substantially perpendicular to at least one of the first and second directions.

3. The dispenser according to claim 1 , wherein the web path is accessible at a level defined between a first support element for the web material and a second support element for the web material, in both the first and second portions of the housing, via the access opening.

4. The dispenser according to claim 1 , wherein the housing comprises a door arranged to open and close the access opening.

5. The dispenser according to claim 1 , wherein the first portion of the housing, seen in a direction from the access opening, is arranged after the second portion of the housing.

6. The dispenser according to claim 1 , wherein the first portion of the housing is arranged adjacent to a first wall of the housing, the first wall being arranged opposite to the access opening.

7. The dispenser according to claim 1 , wherein the second portion of the housing is arranged adjacent to the access opening.

8. The dispenser according to claim 1 , wherein the dispenser comprises a stack of web material arranged in the stack position inside the dispenser.

9. The dispenser according to claim 3 , wherein the first direction extends from the stack position to the first support element, and the second direction extends from the first support element to the second support element.

10. The dispenser according to claim 3 , wherein the web path extends over the first support element.

11. The dispenser according to claim 3 , wherein the second support element comprises a separation unit adapted for separating a sheet of web from a tail of a web material coming from a stack of web material.

12. The dispenser according to claim 3 , wherein the first support element comprises a third roller pivotably suspended inside the housing.

13. The dispenser according to claim 4 , wherein the dispensing opening is arranged in the door.

14. The dispenser according to claim 6 , wherein a guiding element is pivotably arranged inside the housing and arranged to pivot towards the first support element.

15. The dispenser according to claim 14 , wherein the guiding element extends substantially from the first wall of the dispenser to the first support element.

16. The dispenser according to claim 11 , wherein the separation unit comprises a first roller having a first rotation axis and a second roller having a second rotation axis, the first and second rotation axes extending in parallel with each other.

17. The dispenser according to claim 16 , wherein each of the first and second rollers is provided with protrusion elements being spaced along the first and second rotation axes, and wherein outer portions of the protrusion elements on the first roller overlap partially with outer portions of the protrusion elements on the second roller with a radial overlap length forming an undulated passage for a web material between the first and second rollers.

18. The dispenser according to claim 17 , wherein the radial overlap length is between 2-40 mm.

19. The dispenser according to claim 17 , wherein each protrusion element has a widest width in parallel with the first and second axes within the overlap length, and a sum of the widest width of all protrusion elements on one of the first roller or the second roller is between 5-30% of a web width of that roller.

20. The dispenser according to claim 8 , wherein the web material comprises a first web layer divided into sheet products defined between longitudinally separated lines of weakness extending across the first web layer.

21. The dispenser according to claim 20 , wherein the web material comprises at least a second web layer divided into sheet products defined between longitudinally separated lines of weakness extending across the second web layer, and wherein the first and second web layers are interfolded so that the lines of weakness of the first web layer are offset from the lines of weakness of the second web layer in a longitudinal direction of the first web layer.

22. A dispenser for dispensing at least one web from a stack of web material, the dispenser comprising:
a housing arranged to hold a stack of web material, wherein a web path extends in an interior of the housing from a stack position to a dispensing opening of the dispenser, the web path extending in a first direction in a first portion of the housing and in a second direction in a second portion of the housing, the first and second directions being directed in substantially opposite directions, and
wherein the housing comprises:
an access opening in a first side portion of the housing, the access opening providing access to the interior of the housing,

wherein the web path is accessible at a level defined between a first support element for the web material and a second support element for the web material, in both the first and second portions of the housing, via the access opening.

23. The dispenser according to claim 22 , wherein the first direction extends from the stack position to the first support element, and the second direction extends from the first support element to the second support element.

24. The dispenser according to claim 22 , wherein the housing comprises a door arranged to open and close the access opening.

25. The dispenser according to claim 22 , wherein the first portion of the housing, seen in a direction from the access opening, is arranged after the second portion of the housing.

26. The dispenser according to claim 22 , wherein the first portion of the housing is arranged adjacent to a first wall of the housing, the first wall being arranged opposite to the access opening.

27. The dispenser according to claim 22 , wherein the second portion of the housing is arranged adjacent to the access opening.

28. The dispenser according to claim 22 , wherein the web path extends over the first support element.

29. The dispenser according to claim 22 , wherein the second support element comprises a separation unit adapted for separating a sheet of web from a tail of a web material coming from a stack of web material.

30. The dispenser according to claim 22 , wherein the first support element comprises a third roller pivotably suspended inside the housing.

31. The dispenser according to claim 22 , wherein the dispenser comprises a stack of web material arranged in the stack position inside the dispenser.
