Abstract

A dispenser for dispensing sheet products includes a plurality of walls connected to each other, defining an interior volume, and a stack of sheet products received in the interior volume. A removable panel is provided at a top wall of the plurality of walls. The dispenser is configured so that, upon removal of the removable panel, an opening in the top wall for removing sheet products is revealed. The dispenser has a firmness in the range of 20 to 140, in particular, 70 to 90.

First claim

What is claimed is:

1. A dispenser for dispensing sheet products, the dispenser comprising:
a plurality of walls connected to each other, defining an interior volume;
a stack of sheet products received in the interior volume; and
a removable panel provided at a top wall of the plurality of walls,
wherein the dispenser is configured so that, upon removal of the removable panel, an opening in the top wall for removing sheet products is revealed, and
wherein the dispenser has a firmness in a range of 70 to 130 displacement units, wherein the firmness of the dispenser is measured by applying a pressure of 13.9 kPa to the dispenser in a central portion of the top wall in a direction from the top wall towards a bottom wall of the plurality of walls, and, after a lapse of a period of time of 5 seconds after starting an application of the pressure, determining a displacement of the top wall, from its initial position towards the bottom wall, in the central portion thereof where the pressure is applied, and the firmness of the dispenser is defined as the displacement of the top wall thus determined, given in displacement units defined as 1 displacement unit equals 0.1 mm of displacement of the top wall as measured during application of the pressure.

2. The dispenser of claim 1 , wherein each of the sheet products received in the interior volume has a water-absorption capacity in the range of 10 to 15 g/g,
wherein each of the sheet products received in the interior volume has a density in the range of 0.05 g/cm 3 to 0.11 g/cm 3 ,
wherein the sheet products received in the interior volume are cellulose based tissue paper sheet products,
wherein perforations are provided in the top wall, the perforations defining at least a part of the removable panel,
wherein the removable panel is removably attached to a portion of the top wall through perforation bridges arranged between the perforations,
wherein a length of the perforation bridges is in a range of 0.5 mm to 3.0 mm,
wherein the removable panel extends to a side wall of the plurality of walls so that a portion of the removable panel is present at the side wall,
wherein the opening in the top wall has an elongate shape,
wherein the opening extends in the top wall, along a longitudinal direction of the opening, over 90% or less of a length of the top wall in the longitudinal direction of the opening,
wherein the opening extends in the top wall, along a transverse direction of the opening which is perpendicular to a longitudinal direction thereof, over 20% or less of a width of the top wall in the transverse direction of the opening,
wherein the plurality of walls is made of a pliable material,
wherein the plurality of walls substantially has a rectangular prism shape or a cubic shape,
wherein the dispenser further comprises a sleeve arranged so as to at least partially surround the top wall, two opposing end walls of the plurality of walls and the bottom wall,
wherein the sleeve is slidable relative to the plurality of walls,
wherein the sleeve is made of a first material, the plurality of walls is made of a second material, and the second material is more flexible than the first material,
wherein the sleeve has a see-through window arranged at the top wall, and
wherein adjacent sheet products in the stack of sheet products are interfolded with each other.

3. The dispenser of claim 1 , wherein adjacent sheet products in the stack of sheet products are interfolded with each other.

4. The dispenser of claim 1 , wherein the plurality of walls is made of a pliable material.

5. The dispenser of claim 1 , wherein the plurality of walls substantially has a rectangular prism shape or a cubic shape.

6. The dispenser of claim 1 , wherein the removable panel extends to a side wall of the plurality of walls so that a portion of the removable panel is present at the side wall.

7. The dispenser of claim 1 , wherein the sheet products received in the interior volume are cellulose based sheet products.

8. The dispenser of claim 1 , wherein each of the sheet products received in the interior volume has a density in a range of 0.03 g/cm 3 to 0.30 g/cm 3 .

9. The dispenser of claim 1 , wherein each of the sheet products received in the interior volume has a water-absorption capacity in a range of 8 to 18 g/g.

10. The dispenser of claim 1 , wherein perforations are provided in the top wall, the perforations defining at least a part of the removable panel.

11. The dispenser of claim 10 , wherein the removable panel is removably attached to a portion of the top wall through perforation bridges arranged between the perforations.

12. The dispenser of claim 11 , wherein a length of the perforation bridges is in a range of 0.5 mm to 3.0 mm.

13. The dispenser of claim 1 , wherein the opening in the top wall has an elongate shape.

14. The dispenser of claim 13 , wherein the opening extends in the top wall, along a longitudinal direction of the opening, over 90% or less of a length of the top wall in the longitudinal direction of the opening.

15. The dispenser of claim 13 , wherein the opening extends in the top wall, along a transverse direction of the opening which is perpendicular to a longitudinal direction thereof, over 20% or less of a width of the top wall in the transverse direction of the opening.

16. The dispenser of claim 1 , further comprising a sleeve arranged so as to at least partially surround the top wall, two opposing end walls of the plurality of walls and the bottom wall.

17. The dispenser of claim 16 , wherein the sleeve is slidable relative to the plurality of walls.

18. The dispenser of claim 16 , wherein the sleeve is made of a first material, the plurality of walls is made of a second material, and the second material is more flexible than the first material.

19. The dispenser of claim 16 , wherein the sleeve has a see-through window arranged at the top wall.
