DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) FIGS. 1 and 2 show an embodiment of a dispensing closure 10 according to the present invention in a front view and in a side view. The dispensing closure 10 comprises a base 200 and a cover 100, while said cover 100 is attached to said base 200 by means of a hinge 400, so that the cover 100 can be essentially rotated around the hinge 400, as can be also seen in FIGS. 5 and 6 being described hereinafter.

(9) The base 200 is essentially cylindrical and provides an inner thread (see FIGS. 3 and 4), so that it can be attached to a corresponding outer thread of a container, so that the closure 10 can be attached to a container to cover an opening of such a container.

(10) The cover 100 has an outer side-wall 120, which has a curved outer form, and an essentially flat cover plate 160.

(11) According to the invention, the dispensing closure 10 has a push-button region 300 at the outer side-wall 120 of the cover, while said push-button region 300 has an essentially circular form.

(12) The push-button region 300 in this embodiment is connected with or attached to the remaining part of the outer side-wall 120 by means of an intermediate connecting region 320.

(13) In this embodiment, the intermediate connecting region 320 is made of the same material as the cover 100 and the base 120, namely HDPE. However, the thickness of the intermediate connecting region 320 is thinner than the thickness of the push-button region 300 and the remaining part of the outer side-wall 120.

(14) In this embodiment, the side-wall 120 has a thickness of 0.9 mm and generally the thickness of the side-wall is preferably in the area of about 0.6 mm to 2.0 mm.

(15) The thickness of the push-button region 300 in this embodiment is also 0.5 mm and generally the thickness of the push-button region is in an area of about 0.3 mm to 1.0 mm.

(16) The thickness of the intermediate connecting region 320 in this embodiment is 0.2 mm generally it can be in an area of about 0.05 mm to 0.8 mm.

(17) In this embodiment, the material and the thicknesses of the elements are selected such that the intermediate connecting region 320 does not break when the push-button region is moved between the first position (see FIGS. 1 to 3) and the second position (see FIGS. 4 to 6). However, in other embodiments it would be possible to adapt the cover and especially the material and the thicknesses of the elements such that the intermediate connecting region (320) does not break when the push-button region is moved for the first time, from its initial and first position (see FIGS. 1 to 3) to a second position (see FIGS. 4 to 6), however in case the push-button region is pushed back into the first position, e.g. by exerting a pressure against the push-button region from the inside of the cover 100 when said cover is open, the intermediate connecting region will break at least at one or at multiple points or even completely.

(18) As already mentioned above, the push-button region is shown in FIG. 1 to FIG. 3 in its initial and first position, as provided directly after manufacturing of the dispensing closure.

(19) As can be especially well seen in FIG. 2 and FIG. 3, showing the closure with the cover in its closed position, so that the outer surface of the outer side-wall and the outer surface of said push-button region 300 can be seen from a user from the outside, the push-button region 300 has a concave outer surface, and the curvature of the concave outer surface is in this case higher than the curvature of the outer surface of the side-wall 120. This realization is preferred as thereby the push-button region 300 outwardly extends beyond the outer surface of the outer side-wall, so that it can be more easily manipulated by the user, however it is in principle also possible that the push-button region has a concave curvature being essentially equal to a concave outer surface of the side-wall 120, and it would be even possible that the push-button region 300 has an essentially flat outer surface.

(20) FIG. 3 shows a cross-section through the dispensing closure as shown in FIG. 1 along line A-A as indicated in FIG. 1. In this cross-sectional view, the inner threads 210 of the base 200 for an attachment of the closure 10 to a container can be well seen. Furthermore FIG. 3 very well shows a dome-shaped dispensing spout 270, extending essentially upwardly from said base 200 and having a dispensing opening (222, see especially FIGS. 5 and 6).

(21) The cover 100 comprises, on its inner side and extending from said cover plate 160, a ring-like protrusion 162, which extends into said dispensing opening 222 when said cover 100 is in its closed position, thereby sealing said dispensing opening 222.

(22) The dispensing closure 10 of this embodiment also comprises a tamper-evident element 600, which is arranged such that breaking element 610 will break, when said dispensing closure 10 is unscrewed from the corresponding container for the first time.

(23) The base 200 has, on its upper area, a groove 280, into which a lower rim 180 of said cover 100 is inserted (see especially FIGS. 5 and 6). The groove 280 extends nearly around the completed circumference of the dispensing closure, however the groove is not provided in the area where the hinge 400 is provided.

(24) The lower rim 180 of the cover 100 and the groove 280 are dimensioned such that there is a friction between these two elements when said lower rim 180 of said cover 100 is inserted in said groove 280, so that the opening of the cover 100 requires a predetermined minimum force.

(25) FIG. 4 shows the dispensing closure as shown in FIG. 3, however with the push-button region 300 in its second position. This position is achieved by a user who has pushed the push-button region 300, when being in the initial or first position as shown in FIG. 3, e.g. by a fingertip, in an inward direction.

(26) As can be well seen in FIG. 4, the push-button region 300 has, in this second position, a concave outer surface. As can be also well seen in FIG. 4, it is now easily possible for a user to place a fingertip into the concave outer surface of said push-button region 300, which enables the user to exert an opening force onto said cover 100 such that the cover 100 can be opened, in this embodiment essentially by a rotation around the hinge 400, as can be well seen in FIG. 5 and FIG. 6.

(27) FIG. 5 shows the dispensing closure 10 after the cover 100 has been partly opened such that the ring-like protrusion 162 has moved out of the dispensing opening 222.

(28) FIG. 6 shows the dispensing closure 10 with its cover 100 in its completely opened position, so that the dispensing opening 222 is completely free for dispensing liquid or another flowable medium out of a container to be attached to the dispensing closure 10.

(29) It is clear to the expert that various amendments can be made to the embodiments, without departing from the scope of the present invention as defined by the attached claims, and any features disclosed in connection with the embodiments or the general description can be important for realizing the invention, either alone or in any combination thereof.
