Abstract: A fin-sealed, flat-topped, liquid-packaging carton with substantially triangular flaps of its tope end closure turned down and tacked to adjacent body panels has the horizontal part of its fin heat and pressure adhered to the top wall along approximately only that half of its length further from the triangular flap which will provide a pouring spout so that turning upwards of the spout end of the fin from its position flat against the top wall tends to pull upwards the central part of the top wall. Two score lines extending divergingly from the spout end of the top wall at respective opposite sides of the fin to respective corners of the opposite end of the top wall are thereby broken outwards rather than inwards.

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).

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.

Abstract: In a packaging container of parallelepiped type, with material for manufacture of the same, there is, limited by means of fold lines, a fold-out corner flap (4) which contains a pouring opening (7) and serves as a pouring lip when pouring out contents in liquid form from the packaging container. In order to ensure that air can flow into the packaging container in conjunction with the pouring out of the contents the upper end wall (1) of the packaging container is provided with weakening lines (8), which diverge from the pouring opening and weaken the material to such an extent that the area at the rear end of the pouring opening stands out in a raised position obtained on the opening of the packaging container and facilitates the inflow of air.

Abstract: This invention relates to a reclosable sealing carton with a thin polymeric coating. The package is characterized by an extended glue flap scored with a cut-out adapted to form a plug when adhered to the underside of a closure flap and a closure flap overlying the glue flap cut-out of the material of the closure flap. When the consumer opens the closure flap, the cut-out in the glue flap adheres to the closure flap thereby forming a reclosable plug. The closure also comprises a thin, top coating applied to the closure to provide increased durability and resistance to wet handling. The reclosable flap may further comprise a tab facilitating ease of lifting the closing and a recess cut-out of the side panel overlying the glue flap also facilitating ease of lifting.
