ABSTRACT:
A container of rigid material comprises an appliance which employs the contractional force of an expanded rubber hose and expanded product container for the discharge of a medium stored therein. A hollow body of elastic material located in the axis of the product container is provided with a valve at one end through which it is inflated. The shape of the inner walls of the rigid container limits a radial, diagonal-radial and axial expansion of the appliance in a predetermined ratio, whereby the medium acts upon the inflated hollow body in such a way that the volume of the latter decreases, whereby its inner pressure increases and gives it a tendency to expand. If the squeezing pressure exerted by the rubber hose and the product container upon the medium decreases, the hollow body can expand accordingly and thus compensate the loss of contraction pressure.
