A dosing apparatus for fluid, in particular pasty, substances such as toothpaste, liquid soap, mustard, etc., comprises a pump which has a filling nozzle which forms a suction opening of the pump in order to pump the pasty substance out of a container. An adapter has an inlet opening and an outlet opening for connecting a neck or an opening of the container to the filling nozzle of the pump. The outlet opening can be connected to the suction opening. The apparatus includes a two-part adapter housing where the upper part can be substituted for using different sized and shaped containers. The connection between the suction opening of the pump and the outlet opening of the adapter is designed to be releasable. The filling nozzle is formed coaxially to the adapter.

1. An adapter for a dosing dispenser having an inlet opening and an outlet opening for connecting a pump to a container, comprising a fixing element which is arranged on the inlet opening for holding a neck or a connecting portion of the container;a line portion which connects the pump to the container, wherein a valve which determines a flow direction in the line portion is arranged in the line portion;a sealing member which has a sealing membrane which forms a sealed connection between the line portion and the neck or the connecting portion;a housing to which the sealing membrane and the fixing element are fastened,wherein the fixing element is designed to be exchangeable separately from the sealing membrane, wherein the sealing membrane is movable in the axial direction and elastically preloaded by means of a spring element. 2. The adapter as claimed in claim 1, wherein the housing is formed of an upper part and a lower part. 3. The adapter as claimed in claim 2, wherein the fixing element has, on an outer edge, a rib portion which engages in a groove portion on an inner edge of the opening of the upper part. 4. The adapter as claimed in claim 2, wherein a cylindrical portion is arranged between a conical flange of the lower part and a filling nozzle of the pump when it surrounds the filling nozzle. 5. The adapter as claimed in claim 1, wherein the sealing membrane and the line portion are formed in one piece. 6. The adapter as claimed in claim 1, wherein the fixing element has at least one fixing gripper which can be brought into engagement with a connecting portion of the container. 7. The adapter as claimed in claim 1, wherein the fixing element has a screw portion which can be connected to a connecting portion of the container. 8. The adapter as claimed in claim 1, wherein the valve is designed as a nonreturn valve. 9. The adapter as claimed in claim 1, wherein the line portion has, at an end opposite to the sealing membrane, a cylindrical portion which is designed to surround a filling nozzle of the pump if the sealing membrane is pressed in by introducing a neck of a container into the adapter. 10. The adapter as claimed in claim 1, wherein the line portion has, at an end opposite to the sealing membrane, a cylindrical portion which is designed to be introduced into a filling nozzle of the pump if the sealing membrane is pressed in by introducing a neck of a container into the adapter. 11. The adapter as claimed in claim 1, wherein the spring element is designed as a coil spring. 12. The adapter as claimed in claim 1, wherein the sealing member has a double-cylindrical component of an elastic material, wherein two coaxial cylinders are connected to the sealing membrane. 13. The adapter as claimed in claim 12, wherein the valve is arranged in an inner cylinder of the sealing member. 14. A dosing apparatus for fluid substances, including a pump to pump the substance out of a container; andan adapter having an inlet opening and an outlet opening for connecting the pump to the container, the adapter comprisinga fixing element which is arranged on the inlet opening for holding a neck or a connecting portion of the container;a line portion which connects the pump to the container, wherein a valve which determines a flow direction in the line portion is arranged in the line portion;a sealing member which has a sealing membrane which forms a sealed connection between the line portion and the neck or the connecting portion;a housing to which the sealing membrane and the fixing element is fastened,whereinthe fixing element is designed to be exchangeable separately from the sealing membrane,wherein the sealing membrane is movable in the axial direction and elastically preloaded by means of a spring element. 15. The dosing apparatus as claimed in claim 14, wherein a connection between a suction opening of the pump and the outlet opening of the adapter is designed to be releasable and a filling nozzle is formed coaxially to the adapter.
