PACK FOR FILING MATERIALS CAPABLE OF FLOW, HAVING GLASS END WALLS |
摘要 |
Described is a pack for filling materials capable of flow, comprising side walls (1) which are connected together to form a tubular configuration by way of a longitudinal sealing seam, and end walls which are mounted to the ends of the tube and which form the bottom (2) and the top (5) of the pack. In that arrangement the side walls (1) comprise card which is coated with thermoplastic material and the bottom (2) of the pack comprises a separate, substantially flat wall portion and is sealed on the lower edge (3) of the tubular side walls (1). To provide a light, stable and inexpensive pack, the material of which is better utilisd in relation to the filling volume and can also be better re-processed, the invention provides that the bottom (2) and the top (5) comprise glass and are fluid-tightly welded to the tubular side walls (1) and that the top (5) has a closable pouring opening (10). |
