Abstract
A packaging container for the dispensing of a liquid product, more specifically, a carton and pouch system comprising a flexible pouch inserted in a closely form-fitting relationship with an outer relatively rigid carton. A means of access to the liquid in the pouch is provided by a combination of a plurality of intersecting slits superimposed over a through aperature.
Claims5
A packaging container for the dispensing of a liquid product, comprising:
- (a) an outer, relatively rigid casing of carton material including encompassing side wall structure, and top and bottom closure flaps extending from the opposite ends of said wall structure, said closure flaps being inwardly foldable to form end closures and providing a sealed casing structure;
- (b) a through aperture formed in the inner folding flap of one set of end closures, and a plurality of intersecting slits on the outer flap of the same set of end closures, the slits being generally superimposed on the aperture, and adhesive means on the interior surface of the inner folding flap of the end closure, encompassing said aperture;
- (c) a flexible, liquid impervious, thin-walled sealed pouch containing a liquid product, being arranged within said casing, said pouch being dimensioned to have a full volume substantially conforming with the interior volume of said casing, said pouch being adhesively fastened to the inner surface of said casing end provided with the through aperture, said pouch in contact with said adhesive means so as to form a liquid-tight seal about said aperture, between the casing and the pouch, whereby puncturing of the pouch at the location of said aperture facilitates dispensing of liquid from said pouch through said aperture, while concurrently preventing leakage of liquid into the space between said casing and said pouch formed during the emptying of said pouch.
