STOPPER FOR A CONTAINER

Abstract

The stopper for a container having a container opening, in which opening the stopper, having an olive that is molded onto a head segment of the stopper, engages in a force fit, wherein a slide element is arranged in the head segment in a recess leading through the center of the head segment and is guided in lateral grooves such that said slide element may be advanced beyond the lateral edge of the head segment as a grip for removing the stopper from the container, is characterized in that a tension band is attached on the top of the head segment and connects the two longitudinal sides of the recess and covers the slide element with little clearance.

Claims

1. A stopper for a container having a container opening, the stopper comprising a head segment, an olive molded onto the head segment and configured for a force fit in the container opening, a recess leading through the center of the head segment having lateral grooves, a slide element arranged in the recess in the head segment and guided in the lateral grooves such that said slide element may be advanced beyond a lateral edge of the head segment as a grip for removing the stopper from the container, and a tension band attached on a top of the head segment and connected to longitudinal sides of the recess and covering the slide element with little clearance.

2. The stopper according to claim 1, wherein the tension band is embodied as an annular flat strip that is integrally embodied with the rest of the head segment.

3. The stopper according to claim 1, wherein the head segment has an edge that broadens conically downward and in which is inserted, in a starting position, a likewise conical front grip segment of the slide element, wherein the back end of the slide element is positioned against the edge of the head segment.

4. The stopper according to claim 1, wherein the tension band covers the slide element immediately adjacent to the grip segment of the latter.

5. The stopper according to claim 1, wherein the tension band extends to the back end segment of the slide element without covering the latter.

6. The stopper according to claim 1, wherein the top of the tension band has at least one annular thickening.

7. The stopper according to claim 1, wherein the slide element is guided with lateral bars in the grooves, which are in the lateral edge of the recess.

8. The stopper according to claim 7, wherein the lateral bars are connected to the front grip segment of the slide element.

9. The stopper according to claim 1, wherein the slide element in its top has a recessed grip.

10. The stopper according to claim 1, wherein the slide element is a different color than the head segment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0020] The stopper includes an olive 1 that is molded onto the bottom of a head segment 2 of the stopper and that is inserted in a force fit into the container opening of a container (not shown). A desiccant chamber 3 that is filled, for instance, with a loose granulate and is sealed on the bottom, e.g., using a cardboard disk 4, is attached to the head segment 2 radially inside the olive 1.

[0021] The head segment 2 includes an annular edge segment 5 that expands downward conically.

[0022] The center of the top of the head segment 2 includes a recess 6 that extends from the back edge segment 5 to the front edge of the head segment 2 and into which a slide element 7 is inserted that includes a front edge segment 8 that also extends downward conically and seamlessly integrates with the otherwise annular edge segment 5 of the head segment 2 when the stopper is in the starting position.

[0023] An annular tension-band 9 is molded to the top of the head segment 2 and covers the stopper 7 tightly immediately adjacent to the grip segment 8 such that the slide element 7 may be advanced through the tension-band 9 unimpeded. On the back 10 of the stopper the flat tension-band 9 extends to the edge of the recess 6, i.e. without covering the stopper 7 at its back end segment. The top of the tension-band 9 has annular thickenings 11, 12 radially inward and radially outward.

[0024] Embodied on the inside of the recess 6 on the lower edge of the lateral walls are longitudinally oriented guide grooves 13 in which lateral bars 14 of the slide element 7 engage so that the slide element 7 is guided along these guide groves during its movement forward and backward. The lateral bars 14 are integrally attached to the grip segment 8. The top of the slide element 7 includes a recessed grip 18.

[0025] In order to be able to lift the stopper from a container (not shown), the slide element 7 is advanced in the recess 6, wherein the extended position of the grip segment 8 is drawn in with dot/dash lines in FIGS. 1 and 2. The range of movement for the slide element 7 is limited by a stop 15 on the bottom of the recess 6 and a lower projection 16 of the slide element 7 is positioned against said stop. When the slide element 7 is advanced, first the projection 16 must be pressed over a barrier 17 on the bottom of the recess 6. This barrier secures the slide element when it is not in use and provides an audible and tactile click for the user when it is being closed.

[0026] The tension-band 9 holds the lateral walls of the recess 6 at a constant distance from one another in the region of the greatest force so that the lateral bars 14 cannot be pulled upward out of the grooves 13. This also prevents the tension-band from covering the slide element 7. Due to this design, it is always possible to move the slide element 7 inward and outward.
