Core intended to be used as a support for a roll of paper

摘要

A core intended to be used as a support for a roll of paper, especially toilet paper, is formed by winding at least one strip made of tissue, the strip being impregnated, at least locally, with starch so as to improve its stiffness. Thus configured, a core is provided having both a mechanical strength suitable for the envisaged use and a greatly improved ability to disintegrate relative to a cardboard core so as to allow it to be able to be disposed of directly in a toilet bowl without risk of blocking the soil pipe.

1. A core for supporting a roll of paper, comprising:
at least one strip of tissue wound to form a hollow tube, said strip comprising at least one alternation of one ply of tissue in direct contact with a separate non-fibrous layer of starch so as to improve its stiffness, wherein each alternation contains between 0.05 and 0.50 g of starch comprised in the separate non-fibrous layer of starch per gram of ply of tissue.
