Claims

1. An attachment for a milk pump, including a single-walled, substantially dimensionally stable application portion tapering in a funnel-shaped manner from the application opening to a fixing portion provided for connection with the milk pump, wherein the application portion and the fixing portion are interconnected by an articulated connection such that the longitudinal axis of the funnel-shaped application portion is adjustable relative to a longitudinal axis of the fixing portion at an angle deviating from 180°.
2. An attachment according to claim 1, wherein the application portion and the fixing portion are interconnected by a universal-joint connection.
3. An attachment according to claim 1, wherein the application portion and the fixing portion are interconnected by a flexible connecting portion.
4. An attachment according to claim 3, wherein the flexible connecting portion is folded like bellows or corrugated.
5. An attachment according to claim 3, wherein the attachment is made of at least two materials of different hardnesses.
6. An attachment according to claim 5, wherein a thermoplastic elastomer, silicone or rubber is provided as the softer material.
7. An attachment according to claim 5, wherein the softer material has a Shore hardness A of between 20 and 70.
8. An attachment according to claim 5, wherein polypropylene, polycarbonate or another thermoplastic material is provided as the harder material.
9. An attachment according to claim 5, wherein the harder material has a Rockwell hardness R of between 80 and 120.
10. An attachment according to claim 3, wherein the flexible connecting portion comprises at least a further plastic material differing from that of the application portion and the fixing portion.
11. An attachment according to claim 3, wherein at least one web connecting the application portion and the fixing portion is provided in the flexible connecting portion, said web being made of the same plastic as the application portion and the fixing portion.
12. An attachment according to claim 11, wherein a softer plastic is sprayed on the web in the region of the connecting portion.
13. An attachment according to claim 11, wherein the web is ribbed or corrugated.
14. An attachment according to claim 3, wherein the flexible connecting portion is comprised of softer plastic than the application portion and the fixing portion.
15. An attachment according to claim 3, wherein the flexible connecting portion and the fixing portion are comprised of softer plastic than the application portion.
16. An attachment according to claim 3, wherein the attachment comprises struts of the harder material and a cover of the softer material.
17. An attachment according to claim 16, wherein the attachment comprises struts extending in the direction of the longitudinal axis.
18. An attachment according to claim 16, wherein the attachment comprises circular struts arranged perpendicularly to the longitudinal axis in particular, in the region of the application portion.
19. An attachment according to claim 3, wherein the attachment is a one-piece two-component injection molded part.
20. An attachment according to claim 1, wherein the fixing portion is conically designed.
21. An attachment according to characterized in that claim 1, wherein the fixing portion is cylindrically designed.
22. An attachment according to claim 1, wherein the longitudinal axis of the application portion is adjustable relative to the longitudinal axis of the fixing portion at an angle of between 150° and 170°.
23. A milk pump including a pumping device having a suction socket in communication with a funnel-shaped application portion of an attachment to be applied to a mother's breast, wherein the spatial orientation of a longitudinal axis of the funnel-shaped application portion relative to a longitudinal axis of the suction socket is adjustable, wherein an attachment according to claim 1 is provided.
