A method for forming a striped dentifrice wherein a first dentifrice which appears unstriped when stored in a container having sidewalls at least a portion of which is transparent, is transformed into a striped dentifrice upon extrusion from the container, which method comprises storing the first dentifrice in the container provided with discharge means and striping means within the discharge means, sequentially filling the container with a striping dentifrice having a color which distinguishes the striping dentifrice from the first dentifrice, the striping dentifrice being stored in an area of the container separate from the first dentifrice, followed by filling the container with the first dentifrice, apllying pressure on the dentifrices to cause the striping dentifrice to be applied to the first dentifrice within the container area in which the second dentifrice is stored and be simultaneously extruded together from the container, so that upon extrusion, the extruded dentifrice appears to have been magically transformed into a striped body.

La présente invention concerne une méthode permettant d'obtenir un dentifrice à rayures colorées alors même qu'un premier dentifrice sans rayures, contenu dans un tube dont une partie de la paroi au moins est transparente, se transforme en un dentifrice à rayures à sa sortie du tube. Cette méthode consiste à stocker le premier dentifrice dans un tube équipé d'un dispositif de décharge auquel est intégré un dispositif de formation de rayures, à remplir séquentiellement le tube d'un dentifrice à rayures dont la couleur le distingue du premier dentifrice, ce dentifrice à rayures étant logé dans une zone distincte de celle du premier dentifrice, puis à remplir le tube au moyen du premier dentifrice, à exercer une pression sur ces dentifrices pour que le dentifrice à rayures vienne s'appliquer sur le premier dentifrice dans sa zone de stockage de telle sorte qu'à la sortie du tube, le dentifrice uni semble s'être transformé par miracle en dentifrice à rayures.
