The tap has a tap bushing (10) with a passage opening (34) for the liquid to be discharged. A piston (12) is guided so as to move axially within the tap bushing (10) and has an entry opening (36) and an exit opening (38) for the liquid. The piston (12) closes off the passage opening (34) in a locked position when it is moved in. The entry opening (36) of the piston (12) is in connection with the passage opening (34) in an extended position of the piston (12). A locking bushing (14) that is guided to rotate on the piston (12) is seated in the piston (12), which locking bushing (14) optionally closes off the exit opening (38) or brings it into connection with a passage opening (44) of the locking bushing (14).

1. Tap for discharging liquid from a container, with a tap bushing that can be set into an opening in said container, with a seal, said tap bushing is provided with a passage opening for said liquid, and with a piston guided so as to move axially within said tap bushing, said piston has an entry opening and an exit opening for said liquid, whereby said piston closes off the passage opening of said tap bushing in a locked position when it is moved into said tap bushing, and whereby said entry opening of the piston is in connection with said passage opening of said tap bushing in an extended position of said piston, in which it is moved out of said tap bushing, and a flow path through said piston can be released and blocked off by means of rotational activation, wherein a locking bushing that is guided to rotate on said piston is seated in said piston, said locking bushing has a passage opening and can be rotated from a locked position in which it closes off said exit opening of said piston, into a release position in which said exit opening of said piston is in connection with said passage opening, and can be rotated back to a locked position closing off said exit opening of said piston. 2. Tap according to claim 1, wherein said entry opening and said exit opening of said piston lie on its bottom in a common radial plane.3. Tap according to claim 1, wherein said piston has a contact stop to limit its extended position out of the tap busting.4. Tap according to claim 1, wherein said locking bushing is limited by a contact stop that limits its rotational movement in said piston, towards both sides.5. Tap according to claim 1, wherein a shield is provided on said outer face of said locking bushing, and a handle stirrup is divided from this shield.6. Tap according to claim 5, wherein said handle stirrup is provided with an elastic covering.7. Tap according to claim 6, wherein said covering is textured on its surface, in such a way as to improve its feel, particularly it is provided with ribs or ridges.8. Tap according to claim 6, wherein said covering is molded onto said handle stirrup using two-component injection-molding technology.9. Tap according to claim 6, wherein said handle stirrup is connected to said tap bushing at at least one predetermined breaking point, and that said connection consists of said elastic material of said covering.10. Tap according to claim 2, wherein said piston has a contact stop to limit its extended position out of said tap bushing.11. Tap according to claim 2, wherein said locking bushing is limited by a contact stop that limits its rotational movement in the piston, towards both sides.12. Tap according to claim 3, wherein said locking bushing is limited by a contact stop that limits its rotational movement in the piston, towards both sides.13. Tap according to claim 2, wherein a shield is provided on the outer face of said locking bushing, and a handle stirrup is divided from this shield.14. Tap according to claim 3, wherein a shield is provided on the outer face of said locking bushing, and a handle stirrup is divided from this shield.15. Tap according to claim 4, wherein a shield is provided on the outer face of said locking bushing, and a handle stirrup is divided from this shield.16. Tap according to claim 7, wherein said covering is molded onto said handle stirrup using two-component injection-molding technology.17. Tap according to claim 7, wherein said handle stirrup is connected to said tap bushing at at least one predetermined breaking point, and that said connection consists of said elastic material of said covering.18. Tap according to claim 8, wherein said handle stirrup is connected to said tap bushing at at least one predetermined breaking point, and that said connection consists of said elastic material of said covering.
