An expandable container 10 with an enclosing wall and an aperture 94. The container has a first, collapsed configuration and second, expanded configuration in which the wall defines a receiving volume. The container is made from a sheet of material folded along fold line 18 to form a base portion (B, fig 2) and an overlying roof portion T. Preferably the fold line defines an edge of the enclosing wall. There may be material 48, 50 on opposite sides of the fold line which is secured to each other, preferably sealingly. Preferably there is material extending from the ends of the fold line, which is secured together to form flaps 44, 46. There may be handles 90, 92 hingedly or foldably attached above the roof portion. The handles may be made from material either side of the fold line which is secured together. The aperture may be located at the end of a tubular neck portion. |
