摘要

The container for a viscous fluid has an air cushion (6) under pressure inside the outer wall (1). An inlet valve (3) for the introducing of outside air into the air cushion is installed in the outer wall or in the proximity of side lying opposite the outlet opening (2). The outer wall is elastically deformable and through external pressure is temporarily at least partially compressible, whereby the air cushion is put under pressure. A stop may be fitted inside the outer wall to limit its degree of compression.
