A wall section as a constituent of a container, bottle, unit or component can be turned inside out from a concave final position into a convex one and vice versa. The wall section and the adjacent region, for example of a container wall, especially the entire container, are made of an elastically deformable material. The wall section has a stable position in at least one of the final positions, preferably in both. The volume of the container can be reduced by pressing in the wall section which can be turned inside out. A plurality of such containers can be stacked. If the wall section which can be turned inside out is designed as a roof-shaped area, with buckling lines subdividing the roof-shaped area, a tube for insertion and removal of pourable material can be tippably mounted on one of the subdivisions of the roof-shaped area. It can be tipped from a position parallel to the axle for production and filling to an inclined position for delivery of the pourable material, in a spring-loaded fashion. The inside of the end of the tube can be sealed by means of sealing elements in the container or in a screw cap, during retraction. The wall section can be used in a large number of units or components in which tipping movements are necessary. |
