Abstract: The present invention concerns a curtain for an open side of a container, and the container having such a curtain, wherein the curtain comprises a flexible web material, is of an approximately rectangular shape and can be connected along its upper edge to the portion of the container, which is in opposite relationship to that upper edge. In accordance with the invention, the lower left and right corner regions of the curtain are on average per unit of surface area of a greater weight than the average of the remaining areas of the curtain. This allows the curtain to close automatically and independently in a well-defined manner and in so doing completely covers over the front side of the container without a user having to actively intervene apart from pulling down the curtain from the top side of the container or allowing the raised curtain to fall.
