A container of heat-sealable thermoplastic polymeric sheet material is closed at one end by panels integral with the sides of the body and which are infolded in overlapping relation in such manner that only the outer two plies of material at any one location are required to be heat sealed to each other to form a liquid-tight seal. The end closure flaps of a gable-top container are of the configuration shown in Fig. 1, and the heat seal is of H-formation, Fig. 2. |
