Description
~35~X~
The invention relates to a tamper-proof closure for a container/closure with a tamper-proof ring which, in the closed condition, engages the exterior surface of the wall of the container and which is torn away the first time the closure is opened.
Tamper-proof closures are known in many forms. Most frequently, they occur in the form of screw type closures in which the tamper-proof ring is retained by the lower edge of the thread.
Proposals have also been made for closure plugs used, for example, Eor tubes for effervescent vitamin tablets. For instance, the tamper-proof ring may be held to the thickened edge or flange on the tube, in that the inside of the tube is provided with a bead which, by means of different oblique surfaces, allows the plug with the ring to be fitted but the ring is retained upon opening. However, because of the elasticity of the plastic, such a closure cannot be made absolutely safe. It is possible, when opening the closure, to slip the ring over the edge of the tube without using any tool and without tearing the ring.
It is therefore the purpose of the invention to provide tamper-proof closure of the type mentioned above which provides greater safety against opening without tearing the tamper-proof ring.
.. ~
s~
According to the invention, this purpose is accomplished in that the internal cylindrical surface of the tamper-proof ring is provided with tabs directed obliquely inwardly and in the direction of opening, the said tabs engaging under the edge-bead or flange of the wall of the container.
An example of an embodiment o~ the invention is described hereinafter in conjunction with the drawing attached hereto.
Figure 1 is a side elevation partly in cross-section of the tamper-proof closure of the present invention; and Figure 2 is a fragmentary top plan view of the closure shown in Figure 1.
The drawings show a stopper 1 for closing an effervescent vitamin tablet tube.
The stopper 1 has a flat cover part 3 and an outer cylindrical wall 4 which engages over the edge of the tube 2. Peripheral ribs are provided on the cylindrical outer surface of wall 4, to make the stopper 1 easier to grip when it is being opened.
The stopper 1 is provided in known fashion with a resiliently fitted ring 5 which holds down the content of the tube. The stopper 1 also comprises a chamber 6 which is filled with a drying agent 7, closed off by means of a cover 8.
A cylindrical skirt 9, the outside diameter of which corresponds to the inside diameter of tube 2, serves to seal the tube from air and moisture.
In the present case, tube 2 is made of metal, thus a flange 10 is provided at the upper edge thereof.
In the case of a plastic tube, this would be replaced by peripheral enlargement of the edge.
outer-wall 4 engages over flange 10 and secures the stopper 1 to the tube 2.
A tamper-proof ring 11 depends from the wall 4 of the stopper 1. The ring 11 is cylindrical and the connection to wall 4 is effected by means of thin webs 12 which require only a small amount of force to tear.
Eight tabs 13 are mounted to the inside surface of ring 11. The tabs 13 extend obliquely inwardly and-radially in the direction of opening.
The tabs 13 engage under flanged edge 10 of tube 2, and are distributed equidistantly around the periphery thereof, and each have a segment width corresponding to approximately 20 angular degrees. Instead o~ the eigh~
tabs provided in the present example, the desired function may still be obtained by a larger or smaller number of tabs 13. Like the stopper 1, the tabs 13 are made of plastic and are correspondingly resilient.
When the stopper is opened, tabs 13 act as barbed hooks and engage under flange 10 of the tube 2. Ring 11 is thus firmly held and webs 12 tear away when the stopper 1 is removed.
`` ~ 285~a24 In producing tabs 13, the corresponding tool part engaging behind the tab must be inserted from above. For this reason, the cover has the same number of recesses 14.as tabs 13 and the segment width of the recesses 14 must be the same as the corresponding width of the tabs 13.
