ABSTRACT POUCH-LIKE BAGS FOR CONTAINING LIQUID A pouch-like bag for containing a liquid for medical or surgical use has two walls (10,11) formed by respective plies of flexible plastics material sealed together (at 12) around at least their top and side edges and a third, folded, ply (14) of flexible plastics material of sub- stantially smaller dimensions forming a gusset bottom and having opposed leaves (16,17) each of which is sealed (at 18) to the adjacent wall (10,11). The gusset ply (14) carries one or more elements (21,22) of elastomeric mate- rial capable of making an hermetic and liquid-tight seal with a needle, e.g. an administration set needle for a hospital drip-feed system or a hypodermic or injection needle for injecting a drug into the bag contents. The gusset ply (14) is closed below the elastomeric elements (21,22) by a seal (27) between its leaves to form a sealed compartment which can be opened, either by peeling open the seal (27) or by cutting or tearing, whereupon it forms a substantially flat bottom of the bag and presents the elements (21,22) substantially perpendicular to the walls (10,11) for insertion of a needle or needles without risk of accidental penetration of the walls.
