The invention relates to a closure for a container that holds a free-flowing product. The container is characterized by the following: a fixed lower part which can be fastened to a container neck that surrounds a container opening in order to seal said neck; a cover comprising a protruding connecting piece that forms a passage for the free-flowing product; a displaceable upper part which can be coaxially displaced on the lower part in and against the direction of the container between an outer resting position and an inner actuating position; a breaker or dish-shaped diaphragm valve which has a base consisting at least of a flexible elastic material and whose upper edge seals the underside of the upper part; perforations in the base of the diaphragm valve which are closed in the testing position of the upper part; and a diameter of the base that is greater than the inner cross section of the connecting piece. The outer end of the connecting piece continuously supports the base of the diaphragm valve, and the latter continuously pre-tensions the upper part in the direction of its resting position in such a way that, when axial pressure is exerted on the upper part in the direction of the container, the diaphragm valve is bent outwards, thus opening the perforations in the base.

What is claimed is: 1. A closure for container that holds a free-flowing product with a fixed lower part (12), which can be closely fastened to a container neck and a cover (18) with an externally protruding connecting piece (20), whereby a displaceable upper part (14) is coaxially displaceable on
What is claimed is: 1. A closure for container that holds a free-flowing product with a fixed lower part (12), which can be closely fastened to a container neck and a cover (18) with an externally protruding connecting piece (20), whereby a displaceable upper part (14) is coaxially displaceable on the lower part (12) between an outer position and an inner position, a beaker-shaped diaphragm valve (42) consisting of a flexible elastic material, the upper edge (50) of which seals the underside (54) of the upper part (14), having perforations (45) in its base (48), which are closed in the resting position of the upper part (14), and continuously pretensions the upper part (14) in the direction of its outer position, characterized in that the diameter of the base (48) of the diaphragm valve (42) is dimensioned larger than the inner cross section of the connecting piece (20), the outer end of which continuously supports the base (48) of the diaphragm valve (42) so that, when axial pressure is exerted on the upper part (14) in the direction of the container, the base (48) of the diaphragm valve (42) is bent outwards and the perforations (45) of the base (48) are opened. 2. The closure as claimed in claim 1, characterized in that the diaphragm valve (42) is provided with a flange-shaped outer edge (50) that seals the inner side or underside (54) of the cover (18) as well as the inner wall of an inner, cylindrical holder (52) of the upper part (14). 3. The closure as claimed in claim 2, characterized in that a plurality of slits (47) are separated from one another by, preferably, equal circumference angles and form triangular hinged covers (49) that are elastically bendable about their wide base, each in the closing and opening direction. 4. The closure as claimed in claim 1, characterized in that the at least one perforation in the base (48) of the diaphragm valve (42) consists of a slit (47), the length of which is dimensioned smaller than the diameter of the passage (22) of the connecting piece (20). 5. The closure as claimed in claim 1, characterized in that the base (48) of the diaphragm valve (42) is punctured, whereby the punctures are closed in the closing state of the diaphragm valve (42), but are permeable for a free-flowing product in the actuated state, when the base (48) of the diaphragm valve (42) is bulged outwardly. 6. The closure as claimed in claim 1, characterized in that the upper part (14) is provided with a rotary guide jacket (30) extending downwards from the end plate (34), with which the upper part (14) is axially displaceably guided on a guide piece (24) of the lower part (12). 7. The closure as claimed in claim 1, characterized in that cooperating guide and slide walls (24; 30) of the lower part (12) and of the upper part (14) are equipped with an arresting device that determines the resting position of the upper part (14). 8. The closure as claimed in claim 7, characterized in that the arresting device consists of at least one protrusion (28; 32) at the upper end of the outer peripheral surface of a guide piece (24) of the lower part (12) and at the lower end of the inner peripheral surface of a guide jacket (30) of the upper part (14). 9. The closure as claimed in claim 1, characterized in that between the lower part (12) and the upper part (14) a spring element (80) is provided, with which the upper part (14) is continuously pre-tensioned in the direction of its resting position. 10. The closure as claimed in claim 1, characterized in that the diaphragm valve (42) is made of silicone. 11. The closure as claimed in claim 1, characterized in that the diaphragm valve (42) is made of polyethylene. 12. The closure as claimed in claim 1, characterized in that the lower part (12) and the upper part (14) are made of plastic. 13. The closure as claimed in claim 12, characterized in that the lower part (12) and the upper part (14) are injection-molded from polypropylene. 14. The closure as claimed in claim 1, characterized in that the passage (22) of the connecting piece (20) is provided with a hole wall (77) as support for the base (48) of the diaphragm valve (42) in its closing position. 15. The closure as claimed in claim 14, characterized in that a hinged lid (70) is hinged to the upper part (60), the inside of which is provided with a sealing stopper (78) for the discharging piece (64). 16. The closure as claimed in claim 1, characterized in that a discharging piece (64) protrudes from an end wall (62) of the upper part (60). 17. The closure as claimed in claim 16, characterized in that the hinged lid (70) is connected with the upper part (14) in a single piece by means of a film hinge (68). 18. The closure as claimed in one claim 1, characterized in that the lower part (12) is provided with a ventilation opening (82) which is impermeable for the free-flowing product in the container in the region of its cover (18).
