Claim 0:
1. An assembly comprising:
a. a wall element, defining a circumferential bonding strip area running over the wall element, and
b. a flexible flat film connected to the bonding strip with a continuous circumferential bonding, the wall element and film defining two opposite walls of a chamber, characterized in that the wall element further comprises:
a base plane defined by the wall element,
at least two corner elements positioned at a distance from one another, which extend substantially perpendicular to the base plane with a height above the base plane of the wall element, each corner element defining an angle of the chamber with an angle line which is substantially perpendicular to the base plane,
a plurality of strip sections, each strip section connecting two adjacent corner elements, any distance between the strip sections and the base plane being less than said height of the corner elements,
wherein the circumferential bonding strip area runs over the strip sections and over the corner elements and at least in the area of the corner elements at a distance from the base surface corresponding to said height of the corner elements, and wherein an outer contour of the film corresponds to a contour of the circumferential bonding strip area.
