Abstract: A process and apparatus for drawing off deformable masses containing air, such as sausage masses. The mass is transferred in a stream from a supply space into a filling cylinder where a vacuum is generated relative to the space to remove air from the mass, and the transferred mass is then ejected from the filling cylinder by means of a piston. To transfer the mass quickly and remove air from it completely, the mass stream is guided, during its transfer into the filling cylinder in such a way that, as it enters the filling cylinder, it first moves towards the cylinder wall at an angle to the direction of the piston. Moreover, during filling the level of mass in the filling cylinder is maintained at an essentially constant filling height so that a constant volume of free space remains above the mass in the filling cylinder.

Abstract: A resiliently squeezable container is disclosed which is partitioned by a resilient deformable membrane into two chambers, an ingredient chamber, which communicates through an ingredient discharge orifice to the outside, and an air chamber which communicates through a simplistic reclosable valve to the ambient atmosphere. The reclosable valve is such that the pressure within each chamber is held in equilibrium. Thus, on squeezing of the container ingredients are exuded from the ingredient chamber and on release of the container (recovery) air enters through the reclosable valve into the air chamber to re-establish equilibrium between chambers within the container. Thus, by cyclically squeezing and releasing the container, ingredients in the container are instantaneously discharged during each squeeze portion of the cycle. The invention resides in the reclosable air valve which utilizes as the movable element of the valve a portion of the resilient deformable membrane.
