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.
