Container

Abstract

A container, in particular for receiving food, has a wall comprising at least one layer. The container comprises a withdrawal opening with a bent opening edge and is closed at its end opposite the withdrawal opening. At least the container wall is formed from a two-dimensional blank which is connected with itself for forming a continuous container wall. To improve such a container that in a simple constructive and inexpensive manner an inspection of the interior is possible and all advantages of the known containers are maintained, the container and in particular the container wall are at least partially formed from a transparent or translucent, in particular a liquid or fluid tight material which can be shaped for forming the container and which is dimensionally stable after having been shaped. Also, blank for the manufacturer of such a container is provided.
