Abstract: A fluid packaging means comprises tubular side walls and end walls disposed at the ends thereof, forming a bottom and a top, wherein the top comprises thermoplastic material without a carrier material, is injection moulded to the outer edge of the tube along that edge and has a pouring means, and the bottom is quadrangular and has triangular flaps which are folded over to lie against at least one adjacent panel. In order to provide such a packaging means with a particularly advantageous bottom, the invention proposes that at least two mutually oppositely disposed triangular flaps of the bottom are folded inwardly into the plane of the bottom or outwardly on to the side wall, about the lower edge between the bottom and the side wall, and fixed in that position.

Abstract: Apparatus for sealing a liquid package made of paper coated with plastic on at least one surface including a pair of extending fingers that can be inserted in the open end of the package to flatten the top edges thereof into a single strip; a pair of welding jaws to seal the top folded seam strip; and drive mechanisms to operate the fingers and jaws. Each extending finger is flat at its engaging end with the package, the narrow edges of which are rounded in cross section, with its longitudinal axis initially perpendicular to the top of the folded seam strip. The fingers are driven down and out to flatten the top edges and form an elongated seam strip whereafter the welding jaws, driven synchronously with the movement of the fingers, seal and strip the seam strip off the extending fingers.
