The present dual chamber sachet (30) overcomes the problem of non-uniform dispensing when the sidewalls of the sachet are depressed. Through the use of a relatively thin intermediate divider wall (48), rounded corner edges (42) at the lower end of each chamber (32, 35) of the sachet, tapered side edges (44, 46) up to the exit channel (36) of each chamber of the sachet, and a relatively wide dispensing opening uniform dispensing can be achieved. This structure prevents the downward flow of substances in each chamber during dispensing. The substances are directed upwardly by the rounded lower corners of the sachet, the tapered upper walls and the wide dispensing opening. This relatively wide dispensing opening minimizes the back pressure caused by the substances flowing to a dispensing exit of a width less than that of the product chambers.

Le sachet à deux chambres de l'invention (30) résoud le problème de distribution non uniforme lorsque les cloisons latérales du sachet sont enfoncées. Cette distribution uniforme est possible grâce à la présence d'une cloison intermédiaire de séparation relativement fine (48), d'angles arrondis (42) au niveau de l'extrémité inférieure de chaque chambre (32, 35) du sachet, de bords latéraux coniques (44, 46) au niveau du canal de sortie (36) de chaque chambre du sachet, et d'une ouverture de distribution relativement large. Cette structure empêche l'écoulement de substances dans les chambres lors de la distribution. Les substances sont dirigées vers le haut par les angles inférieurs arrondis du sachet, les cloisons supérieures coniques et la large ouverture de distribution. Cette ouverture de distribution relativement large réduit au minimum la contre-pression causée par les substances s'écoulant vers une sortie de distribution d'une largeur inférieure à celle des chambres de produit.
