Abstract: An emptying valve for emptying liquid packages such as sealed liquid pouches, said emptying valve being detachably attachable to the sealed liquid pouch, and said emptying valve having an essentially tubular, mainly hollow and at least one end open body piece, whose that end which is to be attached to the liquid pouch is provided at its distal end with a sharply pointed, liquid pouch wall (13) piercing, at least partially conical tip part (2, 4) having liquid-conducting holes (12) made to its wall, whereby the holes communicate with the hollow interior of said tubular body piece, and at least immediately after the tip part (2, 4) the diameter of the tubular body piece (1) being provided with an outer thread after the tip part (2, 4), whereby a tightening element 97) with a mating inner thread can be rotated thereon so as to tighten the element against the collar.

Abstract: A strip made up of consecutive package blanks has been described. This strip consists of cardboard and has continuous longitudinal folding lines, which divide each blank into longitudinal zones, and in each blank four transversal folding lines which divide the blank into five transversal zones. Thus each blank can be folded to become a package wherein the centermost transversal zone constitutes the rectangular sides of the package, the transversal zones following on either side and which have on the areas of the longitudinal zones, which in the folding process come to be opposite each other, oblique folding lines enabling a folding up constitute the ends of the package and the edgemost transversal zones constitute at the ends seams which close the package. The seams are formed by cardboard layers that are lying against each other and bonded together with the aid of plastic.
