Abstract
The invention relates to a closure system for a container comprising a closure and container opening portion. The closure releasably seals the container opening and has a cylindrical collar comprising a plurality of elastically designed tabs. The free ends of the tabs deflect radially and comprise latching elements on at least one part At least one radially extending holding element is molded on the enveloping surface of the container and forms a snap-in connection with the latching elements. A plurality of guidance elements interact with the tabs and latching elements such that upon rotation of the closure in an opening direction, a spreading of the tabs radially releases the snap-in connection.
Claims15
A closure system (1) for a container (2) comprising:
- a) a closure (3) comprising:
- i) a cup shaped body with an opening (20);
- ii) a cylindrical peripheral collar (5);
- iii) a plurality of elastically embodied tabs (6) extending peripherally from said collar, each of said tabs ending in a free end (7) deflectable in springing fashion in a radial direction;
- iv) a latching element (8) configured on each free end (7) of each of said tabs (6);
- b) a cylindrical container opening (4) comprising:
- i) at least one holding element (9) configured as a circumferential ring or segmented ring with interstices adjacent said opening (4), said element extending radially from and shaped onto an enveloping surface (10) of said container (2);
- ii) an enveloping segment (11) defined as that portion of enveloping surface (10) of said container (2) residing between said opening (4) and said holding element (9);
- iii) a plurality of teeth-shaped container-side guidance elements (12) positioned circumferentially around said container opening (4) and against said holding element (9), each of said guidance elements (12) further comprising an outwardly directed flank (13), a first flank end (14) on said enveloping segment (11), a second outwardly directed flank end (15), and a bevel (17);
- wherein the closure (3) and the opening (4) are configured and dimensioned such that in the closed position, said closure (3) releasably closes off container opening (4);
- the at least one holding element (9) and said tabs (6) configured and dimensioned such that said latching elements (8) of said tabs (6) constitute with the at least one holding element (9) a snap-in connection by which said closure (3) is releasably secured on the container opening (4);
- and wherein said guidance elements (12) interact with said tabs (6) and latching elements (8) such that upon rotation of the closure (3) out of its closed position, tabs (6) deflect out in a radial direction such that the snap-in connection between the at least one holding element (9) and the latching elements (8) of the tabs (6) is released.
