Patent

CA 2745950

The invention relates to a core intended to support a reel of paper, particularly toilet paper, said core being formed by winding at least one web of cellulose wadding. The core is characterized in that it is formed by winding at least one web of cellulose wadding comprising at least 0.51 g of water-soluble material per gram of cellulose wadding, the water-soluble material being designed to make the web of cellulose wadding more rigid and easier to disintegrate. Thus configured, the invention is able to provide a core that has both mechanical strength fit for the intended purpose and is far easier to disintegrate than a core made of cardboard such that it can be disposed of directly in the toilet bowl without the risk of blocking the waste pipe.

L'invention concerne un mandrin destiné à servir de support à une bobine de papier, notamment de papier toilette, ledit mandrin étant formé par l'enroulement d'au moins une bande en ouate de cellulose, Le mandrin est caractérisé par le fait qu'il est formé par l'enroulement d'au moins une bande d'ouate de cellulose comprenant au moins 0,51 g d'un matériau hydrosoluble par gramme d'ouate de cellulose, le matériau hydrosoluble étant déterminé pour conférer rigidité et délitabilité à la bande d'ouate de cellulose. Ainsi configurée, l'invention est susceptible de fournir un mandrin possédant à la fois une résistance mécanique adaptée à l'usage envisagé et une délitabilité fortement améliorée par rapport à un mandrin en carton de manière à lui permettre d'être directement jetable dans une cuvette de toilette sans risque de bouchage du conduit d'évacuation.
