The invention relates to a device (1) for expelling viscous masses (4.5) from a container (4) according to figure 1. Said device comprises: a first tube (2), closed on one end and having an internal screw thread (2.1) which extends from a closed end (2.5) to an open end (2.6), a piston rod (2.2), which is arranged centrally at the closed end (2.5) and extends in the direction of the center axis (L), and a piston (2.3), which is arranged vertically to the piston rod (2.2), being provided and moving a piston (2.4) that can be moved in a product-tight manner in (4) in a controlled manner; a second tube (3), closed on one end and having an outer screw thread (3.1) which is complementary to the internal screw thread (2.1) and which extends from a top, open end (3.4) down to the region of a lower, partially closed end (3.2); and a center opening (3.3) in the partially closed end (3.2); and a container (4) inserted in (3) and having a wall (4.3) which is open toward the top in the region of the open end (4.2); an exit device (4.4) on the bottom (4.1) of (4) and arranged in the center opening (3.3), (4) being filled with a viscous mass (4.5); and a piston (2.4) which can be moved along the center axis (L) in a product-tight manner and which is arranged so as to be moved by means of the piston (2.3). |
