A dispensing closure (10) for a drinks container, having a closure body (100), the passage opening ( 126) of which is in communication with the outlet opening of the container, a closure element (200) and a flexible dispensing tube (300). A pinch member (280) is arranged on the closure element (200
A dispensing closure (10) for a drinks container, having a closure body (100), the passage opening ( 126) of which is in communication with the outlet opening of the container, a closure element (200) and a flexible dispensing tube (300). A pinch member (280) is arranged on the closure element (200 ), and a mating holder (180) is arranged on the closure body ( 100). A cover (120) of the closure body (100) has a stepped stub ( 124) with an outlet opening ( 126) for the flexible dispensing tube (300). The flexible dispensing tube ( 300) is matched to the stub (124). An annular shoulder of the flexible dispensing tube ( 300) bears against an annular stop face (130) of the flexible tube holder ( 122, 124) and is widened by an annular bead (332) which engages in an annular groove ( 132) of the second step (134) . The flexible dispensing tube (300) covers the annular shoulder ( 122). When the closure element is being closed, the head plate (210) can be fitted over the flexible tube holder (122, 124) , in such a manner that the flexible dispensing tube (300) can be bent over by means of this pinch member (280).

What is claimed is: 1. A dispensing closure ( 10) for containers which contain free-flowing substances, in particular for drinks containers, comprising a) a closure body (100) having a cover (120), from the outer edge of which projects a casing ( 110) which can be secured to the container over an outlet opening thereof, b) a passage opening (126) in a top side of the closure body (100 ), which opening is in communication with the outlet opening of the container, c) a closure element (200), which is connected to the closure body (100) and can be moved between a position in which it closes off the passage opening of the closure body (100) and a position in which it opens up the passage opening of the closure body ( 100), d) a flexible dispensing tube (300), the passage opening (126) of the closure body (100) being designed in such a way that it can accommodate the elastic dispensing tube (300 ) for the free-flowing substance, which can be sealed by being pinched shut when the closure element ( 200) moves out of the open position into the closed position, characterized in that e) the closure element (200) is provided with a pinch member (280), f) the closure body (100) is provided with a mating holder (180), in such a manner that when the closure element ( 200) is being closed the flexible dispensing tube ( 300) can be moved onto the mating holder ( 180) by the pinch member (280) in order to pinch shut the flexible dispensing tube (300) in a sealing manner, g) the pinch member (280) is arranged on the underside of a head plate ( 210) of the closure element (200), and the mating holder ( 180) is arranged on the top side of the closure body (100), h) the pinch member (280) and the mating holder ( 180), in the closing position of the closure element ( 200), are arranged in such a way that the distance between them in the area into which the flexible dispensing tube (300) is forced by the closure element (200) closing corresponds to at most the thickness of the flexible dispensing tube which has been sealed by pinching, such that the pinch member (280), in the closed position of the closure element (200), pinches the flexible dispensing tube (300) shut on the mating holder (180) in a sealing manner, i) the closure element (200) forms a flap lid which is articulatedly mounted integrally on the closure body (100) by a hinge (290), j) the cover (120) of the closure body (100) is designed as a flexible tube holder with a radially outer annular shoulder (122) and a radially inner dome-like stub (124), the diameter of the dome-like stub (124) being stepped over the height of this stub, and the dome-like stub having, at its outer end, the passage opening ( 126) for an outer section (310) of the length of the flexible dispensing tube (300), k) the internal and external diameters of a section of the length of the flexible dispensing tube (300) which is arranged inside the stepped flexible tube holder (122, 124) are matched to the steps in the internal diameter of the flexible tube holder (120), l) a first step (128) is provided by cylindrical widening of the flexible tube holder (122, 124) below its passage opening (126), m) the lower end of this first step (128) of the flexible tube holder (122, 124) forms an inner, annular stop face (130), which at the same time delimits an annular groove (132) inside a second step (134), the diameter of which is widened with respect to the first step (128), n) the widening of the second step (134) below the annular groove (132) is of frustoconical configuration and, at the lower end, merges into the horizontally positioned annular shoulder ( 122) which faces the edge of the container opening and from the outer edge of which the securing casing (110) of the closure body ( 100) extends toward the container, o) the flexible dispensing tube (300) has a widened diameter at a distance below the outlet opening (126) of the axially stepped flexible tube holder ( 122, 124) and at the lower end of this widening has an annular shoulder (330), by means of which the flexible dispensing tube ( 300) bears against the annular stop face ( 130) of the flexible tube holder (122, 124), p) the annular shoulder (330) of the flexible dispensing tube (300) is widened by an annular bead (332) which engages into the annular groove (132) of the second step ( 134) of the flexible tube holder (122, 124), q) the flexible dispensing tube (300) has a cylindrical section (340) of its length extending from its annular shoulder (330 ) to an inner edge of the annular shoulder (122 ) of the cover ( 120) and has a disk-like widening (350) which substantially covers the underside of the annular shoulder ( 122) of the cover (120), r) the underside of the head plate (210) of the closure element (200) is provided with the pinch member (280 ), in such a manner that when the closure element is being closed, it can be fitted over the flexible tube holder (122, 124), which forms the mating holder (180), in such a manner that when the closure element (200) is being closed the flexible dispensing tube (300) can, by means of this pinch member (280), be bent over the edge of the passage opening ( 126) of the flexible tube holder (122, 124) and can be sealed by being pinched shut. 2. The dispensing closure as claimed in claim 1, characterized in that the closure element (200) is articulatedly mounted on the closure body (100) by means of an integral hinge (290). 3. The dispensing closure as claimed in claim 1, characterized in that the closure element (200) can be latched in the closed position with respect to the closure body (100). 4. The dispensing closure as claimed in claim 1, characterized in that the pinch member (280) is designed substantially in the form of a continuous curve with different radii, the radii being selected in such a way that the pinch member (280), in the closed position of the closure element ( 200), bears, by means of its side which faces the hinge (290), against that side of the flexible tube holder (122, 124) which faces the hinge ( 290), whereas that side of the pinch member (280) which is remote from the hinge (290), in the closed position of the closure element (200), opposite that side of the flexible tube holder ( 122, 124) which is remote from the hinge (290), forms, together with the flexible tube holder (122, 124), a free space for accommodating the bent-over, free end (310) of the flexible dispensing tube (300). 5. The dispensing closure as claimed in claim 1, characterized in that a substantially cylindrical through-channel ( 360) in the flexible dispensing tube (300) is widened in steps toward its inner end, matching the stepped contour of the flexible tube holder (122, 124). 6. The dispensing closure as claimed in claim 1, characterized in that the flexible dispensing tube consists of silicone. 7. The dispensing closure as claimed in claim 1, characterized in that the closure body (100) is provided with a sleeve element (150) which at least partially covers the flexible tube holder (122, 124). 8. The dispensing closure as claimed in claim 7, characterized in that the sleeve element (150) consists of a soft material, in particular silicone or rubber.
