The present invention concerns a dosing feeder design for cream-like mixtures, or for fluids of other consistencies. The dosing feeder is connected to a container via a cylindrical connection piece 1 with a cylindrical flange forming a valve seat 3. The dosing part 6 proper consists of a downwards-tapering circular tube of flexible material. The lower part of the tube is shaped to a discharge opening 9 with a valve seat 10. In the tube there is a valve body 11 formed of an elongate, preferably tube-shaped, downwards-tapering section 12 with an upper end designed to function as a valve cone 13, operating in conjunction with the valve seat 3 to form a non-return valve. The valve body's lower end forms a valve cone 14 to operate in conjunction with valve seat 10. The connection piece 1 and the dosing part 6 are held together by the locking piece 5. <IMAGE> |
