Abstract
A dispenser packing for viscous or pasty material, comprising a cylindrical container; a piston slidingly movable in said container which divides the interior of the container into an upper chamber for receiving the material and a lower chamber; an expulsion valve for the material at the upper end of the container; a charging valve at the lower end of the container; a hose-shaped or pouch-shaped expulsion element which is connected to the portion of the charging valve which is inside the container and is adapted to be filled with a propellant gas under a pressure, and which abuts, on an outer wall portion, against the piston under a pressure.

A dispenser packing for viscous or pasty material, comprising:
- a cylindrical container having an upper end and a lower end, the lower end being formed by a lid,
- a piston slidingly movable in the container which divides the interior of the container into an upper chamber for receiving the material and a lower chamber,
- an expulsion valve for the material at the upper end of the container,
- a charging valve mounted to the lid at the lower end of the container, the charging valve having a charging valve chest, a valve body, and a valve element within the valve body,
- a hose-shaped or pouch-shaped expulsion element connected to the valve body of the charging valve and located inside the container and adapted to be filled with a propellant gas under pressure through the charging valve and which abuts, on an outer wall portion, against the piston under pressure.
