Abstract

L'invention concerne un rouleau de papier toilette capable de réduire sensiblement le bruit de déroulement lorsqu'il est utilisé comme rouleau, qui permet d'améliorer une mesure de traitement des déchets par écrasement et élimination aisés de l'âme épaisse du rouleau de papier, de réduire ses coûts de production, d'écouler l'âme épaisse dans des toilettes et, lorsqu'il est utilisé, de le rétablir d'ordinaire suivant une forme de section circulaire pour la commodité d'emploi. Les coûts de stockage et de transport sont ainsi réduits. Le rouleau de papier toilette comprend l'âme épaisse (1) à base de papier mince d'environ 4 cm de diamètre extérieur. Le papier toilette (2) est d'ordinaire enroulé en douceur autour de l'âme épaisse (1) du premier jusqu'au dernier. Ladite âme épaisse est plate selon les besoins; le papier toilette (2) l'est également, mais de forme elliptique de façon à épouser l'âme épaisse (1) plate.
