Benefits of technology

The stacks in this patent have a larger surface area than previous stacks, making them easier to handle and refill dispensers with. The new handling method also reduces the risk of adhesions between the web materials and requires less adhesion material. The front and back surfaces of the stack are the largest, which also helps prevent the webs from becoming asynchronous during feeding. Overall, this patent provides a way to provide more web material in a single stack and improve the refill procedure of dispensers.

Problems solved by technology

The rolls are often heavy and there is a friction and resistance for unrolling the paper.
Thus, the products may run out before the next servicing and products may not always available to the user when needed.
More frequent servicing means a higher labor cost which often is undesirable.
The selection of dispensers is often limited and they are only found in a few fixed sizes, which thus limits the design of the hygienic products as well.
Accordingly, the refill of a large dispenser may be rather time-consuming.

Embodiment Construction

[0090]FIG. 1 together with FIG. 12 illustrate an embodiment of a stack 1 of web material for hygiene products, for use in a dispenser. The stack 1 comprises at least one continuous web material 2, 3 being Z-folded about transverse folding lines, thereby providing panels having a length L along said folding lines, and a width W perpendicular to said folding lines. The panels are piled on top of each other to form a stack, having a height H. Accordingly, said stack outlines a rectangular parallelepiped having said length L, width W and height H. The parallelepiped will have six outer surfaces:[0091]A top surface 5 and a bottom surface 6, both being parallel to the panels of said stack 1[0092]Two side surfaces 7, 8, which are generally formed by the longitudinal edges of the Z-folded web material.[0093]A front surface 9 and a back surface 10, which are generally formed by the folded edges of the Z-folded web material.

[0094]As explained in the above, with “continuous web material” is me...

Abstract

A stack of web material for hygiene products, for use in a dispenser, including at least one continuous web material being Z-folded about transverse folding lines, thereby providing panels having a length along the folding lines, and a width perpendicular to the folding lines, the panels being piled on top of each other to form a height of the stack, such that the stack outlines a rectangular parallelepiped having the length, width and height, and forming six outer surfaces, namely a top and a bottom surface, being parallel to the panels of the stack, two side surfaces, including the longitudinal edges of the web material, and a front and a back surface, including the folded edges of the web material. The height of the stack is greater than 17 cm.

Description

TECHNICAL FIELD[0001]The present invention relates to a stack of web material for hygiene products, for use in a dispenser, comprising at least one continuous web material being Z-folded about transverse folding lines, thereby providing panels having a length along said folding lines, and a width perpendicular to said folding lines, said panels being piled on top of each other to form a height (H) of said stack.BACKGROUND[0002]Dispensers with web material, such as paper towels, napkins and similar hygiene products are often used in public lavatories as a convenient way of providing a supply of towels in washrooms and other facilities. Similar dispensers with web material are provided for supplying hygiene products intended for object wiping, e.g. for cleaning.[0003]The web material may either be provided as a rolled web or as a stack of folded web. The rolls are often heavy and there is a friction and resistance for unrolling the paper. In addition, an arresting force is required in...
