Abstract

The sack with lining and valve comprises a first tube of material, closed at one end, forming the outside of the sack, inside which a second such tube forming the lining fits, its open end protruding outside that of the first one. A corner of the open end of the outside and the corresponding corner of the lining are folded inwards to form an opening (24, 26), while the rest of the open ends of both are closed. The part of the lining folded inwards and which previously protruded beyond the outside before folding forms a filling sleeve or valve. The centre line of this sleeve can run at right angles to the lengthwise axes of lining and outside.
