Abstract

Described is a cardboard box for pourable material, in particular liquids, consisting of a folding box having a rectangular base section and made of cardboard, and an inner bag disposed therein. At its upper end, the body of the folding box is provided with a circumferential collar adapted to be folded inwards for closing the folding box, and a cover flap extending from a portion of the collar for covering the end portion of the inner bag projecting from the collar in its sealed and flattened-down condition in the adhesively secured state of the flap. The cover flap is provided with a portion formed as a tearing tab permitting the folding box to be torn open together with a section disposed therebelow of the upper end portion of the inner bag. In this manner it is possible to form a pouring spout of the type already generally known from milk packages.
