Abstract

A safety closure device 1 in the form of a cap for a bottle has inner and outer closure members 2 and 3 respectively, the inner one of which has an outwardly directed radial flange 13, of triangular cross-section, which maintains a desired distance between skirts 7 and 8 of the members 2 and 3 so that the outer one cannot be tilted or squeezed to engage dogs 9 and sockets 10 by which the device is removed from the container. <IMAGE>

Description

SPECIFICATION A closure device for a container having a cylindrical opening The invention relates to a closure device for a container having a cylindrical opening, such as a med icine bottle having a screw neck.
Such closure devices are often designed to be a Safety closureRwhich cannot readily be removed from the neck, for reasons of safety or security so that unauthorised removal of the contents of the bottle for example by a child is obviated or hind ered. However, sometimes it is possible to force such a cap off the neck of the bottle even when ostensibly screwed engaged thereon.
It is an object of the invention to seek to mitigate this disadvantage.
According to the invention there is provided a closure device for a container having a cylindrical opening, comprising an inner closure member and an outer closure member normally urged apart by biassing means, the inner and outer members each including an end member skirt member and means to drive the inner and outer members in unison to remove the device from a container opening when the outer closure member is de pressed against the action of the biassing means and rotated, wherein there is means between the inner and outer members to prevent operation of the drive means on transverse pressure being ap plied to the inner and outer members whereby unauthorised removal of the device from the con tainer is prevented or hindered.
The means between the inner and out members may comprise a radial stop on one member which may project towards and engage the other mem ber.
The radial stop may comprise a circumferential flange.
The flange may be carried by the skirt of the in ner member.
The flange may be carried by the skirt of the in ner member adjacent the free edge thereof.
The flange may be substantially triangular in cross- section.
The skirt of the outer member may shroud the skirt of the inner member.
A closure device, for a container having a cylin drical opening, embodying the invention, is shown by way of example with reference to the accompa nying drawing.
Brief description of drawing The only Fig. of the drawing shows a closure de vice according to the invention mounted on a screw-threaded neck of a medicine bottle.
Referring to the drawing, there is shown a clo sure device 1 comprising an inner closure member 2 and an outer closure member 3 normally urged apart by biassing means in the form of resilient tabs 4 projecting from the inner (as viewed) of an end member 6 of the inner closure member 2.
The outer closure member 3 has a skirt member 7 depending from the end member 5. Likewise, the inner closure member 2 has a skirt member 8 depending from the end member 6. There is between the inner and outer closure members means in the form of driving dogs 9 engageable in sockets 10 which engage when the outer member 3 is depressed longitudinally against the biassing means 4 to overcome the force thereof to drive the inner and outer members 2 and 3 in unison to unscrew the closure device 1 from neck 11 of bottle 12. (It will be understood that the device 1 is screwed onto the neck 11 by rotating the device so that ratchets and pawls (not shown) engage to drive the members 2 and 3 in unison, the ratchets clicking over the pawls in the unscrewing direction if the dogs and sockets are not engaged).
There is between the inner and outer members 2 and 3 means in the form of an integral outwardly projecting radial flange 13 carried by the skirt 8 of the inner member 2 which engages the skirt 7 of the outer member 3 and which prevents the dogs 9 being engaged with the sockets 10 on canting or tilting of the outer member 3 on transverse pressure being applied to the inner and outer members 2 and 3. Effectively, the flange 13 acts as a radial stop to prevent the outer member 3 being tilted far enough to engage at least one dog 9 with a socket 10 so that even on a rotational motion, the closure device 1 will not be unscrewed. The flange or stop 13 acts to maintain the desired spatial relationship or integrity of the inner and outer members 2 and 3, so preventing unauthorised removal of the closure device 1 from the neck 11.
The flange 13 is adjacent the free end of the skirt member 8 and is generally triangular in cross-section.
As shown, the outer skirt member 7 shrouds the inner skirt member 8.
Both inner and outer members 2 and 3 are injection moulded from plastics material in a one shot injection moulding operation.
1. A closure device for a container having a cylindrical opening, comprising an inner closure member and an outer closure member normally urged apart by biassing means, the inner and outer members each including an end member a skirt member and means to drive the inner and outer members in unison to remove the device from a container opening when the outer closure member is depressed against the action of the biassing means and rotated, wherein there is means between the inner and outer members to prevent operation of the drive means on transverse pressure being applied to the inner and outer members whereby unauthorised removal of the device from the container is prevented or hindered.
2. A closure device according to Claim 1, the means between the inner and out members comprising a radial stop on one member projecting towards and engaging the other member.
3. A closure device according to Claim 2, the radial stop comprising a circumferential flange.
4. A closure device according to Claim 3, the
