ABSTRACT:
The invention relates to a dosing and filling arrangement for containers of fluid or pasty masses, in particular contaminant-free nutrient material, such as milk, yogurt, pudding, desserts or the like. The arrangement includes a housing having two axially movable pistons. A first of such two pistons is a dosing piston and a second independently movable piston is the valve piston which is coaxially arranged relative to the dosing piston. The arrangement also has a mouthpiece on the lower side of the housing which is coaxial with the dosing and valve pistons. The valve piston rod is centrally arranged in a bore of the dosing piston and the hollow piston rod of the dosing piston is slidably movable in a cylinder of the housing. The piston rod has advantageously a plurality of equiangularly disposed longitudinal slots disposed on its periphery. The piston rod has a first control collar which coacts with the mouthpiece of the housing. This first control collar is connected via a push rod to a second control collar. Such a dosing arrangement makes possible a gentle filling operation as well as an easy cleaning of the arrangment. The arrangement, moreover, is, due to its simple construction inexpensive to manufacture.
