A process and apparatus for forming a dual compartment package includes forming an elongated rectangular U-shaped package (10) having an inside (14A) and outside wall (14B) configured to form an open bottom end (20). The U- shaped package (10) is filled product. A zipper assembly (36) having inter- locking members is separated into a first zipper component (24) and a second zipper component (40). The first zipper component (24) is attached to the inner side of the open top end walls (18) thereby sealing the top end of the first zipper component. The open bottom end walls are placed adjacent to the first zipper component, and the second zipper component is reattached to the first zipper component thereby locking the open bottom end walls between the interlocking members of the zipper assembly. The U-shaped package (10) forms two compartments that are separately filled with a product, in which the product is dispensed from the bottom end of the package after one of the interlocking members is released for the sealing/release assembly. The dual compartment package can also be formed with two separate compartments.

L'invention concerne un procédé et un appareil permettant de former un emballage à deux compartiments, qui consiste à former un emballage (10) rectangulaire allongé en U à parois intérieure (14A) et extérieure (14B) configurées de façon à former une extrémité inférieure (20) ouverte, l'emballage en U (10) étant rempli d'un produit. Un ensemble fermeture (36) à glissière doté d'éléments d'interverrouillage est séparé en un premier composant (24), et un second composant (40). Le premier composant (24) est fixé au côté intérieur des parois d'extrémité (18) supérieure ouvertes, ce qui permet de fermer l'extrémité supérieure dudit premier composant de manière étanche. Les parois d'extrémité inférieure ouvertes sont placées adjacentes au premier composant (24), tandis que le second composant est fixé audit premier composant verrouillant ainsi les parois d'extrémité inférieure ouvertes entre les éléments d'interverrouillage de l'ensemble fermeture à glissière. L'emballage en U (10) forme deux compartiments remplis séparément d'un produit, ledit produit étant distribué depuis l'extrémité inférieure de l'emballage une fois que les éléments d'interverrouillage ont été libérés de l'ensemble de fermeture d'étanchéité/libération. L'emballage à deux compartiments peut également être formé de deux compartiments séparés.
