Abstract
Described is a cardboard box package having an inner bag and wherein three of four top cover flaps are integrally interconnected, with the intermediate one of said cover flaps extending from a side face of the box being folded to the shape of a triangle and folded down onto the top face of the cardboard box. The inner bag has its sealed upper end portion partially passed between the cover flaps and locally bonded thereto. Outwards folding of the triangularly folded cover flap and tearing a section of the inner bag end portion off permits a pouring spout to be formed and the package to be thereby opened (FIG. 1).
