Abstract

A device for resealing an opened ring-pull can 100 comprises means 12 for sealingly engaging an opened dispensing orifice, gripping means 32 to retain the device in sealing engagement with the can, and attachment means 22 to allow the device to be releasably attached to a support. <IMAGE>

Description

Improvements relating to cans for liquids.
The invention relates to a handle for a can of the kind generally known as a 'ring pull' can commonly used to contain a liquid typically a beverage. Such cans are provided with a 'ring pull' portion which, when levered away from the can body either pushes a portion of the can wall into the can so forming an orifice to give access to the contents, or of the kind where a portion of the can wall is removed with the 'ring pull'. It is to be noted that with the former type of beverage can no part is detached from the body of the can and the ring is still attached to the can and is folded back substantially to its original position after forming the orifice. It is primarily this kind of can to which the invention relates, and hereinafter such cans will be referred to as a 'push-tab' cans. The latter type where a portion is removed will be referred to as 'tear-tab' cans.The term 'ring pull' can encompasses both types.
It is a disadvantage of ring pull cans that once opened they are difficult to reseal. Thus, once opened the can must be treated as one would a cup or beaker, or else the beverage will be spilt, and thus all the contents must generally be consumed 'at one sitting'.
The present invention seeks to provide a means of overcoming at least some of the foregoing disadvantages.
The present invention provides a resealing device for temporarily re-sealing an opened ring pull can of liquid comprising sealing means operable to sealingly engage the opened dispensing orifice of a can, gripping means operable to retain the device in sealing engagement with the can, and attachment means operable to allow the device to be releaseably attached to a support.
Preferably, the sealing means comprises a portion shaped to be received in the said orifice, and a shoulder portion provided on the sealing means to lie on the surface of the can at the periphery of said orifice. The sealing means may also include a thin laminar tongue having a concave front edge for cooperation with the underside of a retained ring pull of a push-tab can.
Preferably the gripping means comprises a hooked portion adapted to engage a bottom rim of the can and attached to the sealing means by a limb. The limb is of resilient material and formed such that the hooked portion and sealing means have to be forced apart against resilient urging of said limb to enable the device to be operatively deployed on a can, so gripping the can.
Said resilience acts to urge the sealing means into sealing engagement with said orifice and allows tolerance in the range of sizes of can with which the device is able to be deployed.
Preferably second gripping means are also provided near the sealing means to grip a top rim of the can.
Said second gripping means also help to locate the sealing means relative to the orifice.
The limb is preferably provided by an arcuate portion of resilient plastics material and usefully provides a handle for the can.
The attachment means preferably comprises an arcuate finger depending from the limb and lying alongside it with a free end of said finger disposed away from said sealing means, the finger being made of resilient material (desirably the same material as the limb and in one piece) so that the finger is urged by its own resilience towards the limb. Thus a flap of a pocket or the waistband of a pair of trousers or a belt of a wearer may be received between the finger and the limb and so the finger resiliently grips said flap etc against the limb thus holding the resealing device (and any can to which it is attached) to said flap etc, with the (sealed) orifice uppermost.
The device may be displaced circumferentially so that the can is still gripped by the device but the opened can orifice is exposed.
Thus the limb acts as a handle whilst the contents of the can are able to be dispensed or drunk from the orifice.
Resealing devices according to the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Fig.l is a perspective view from below and one side of a resealing device according to the invention shown before fitting to a push tab can, Fig.2 is a longitudinal section through a centre line of the device of Fig.l, on an enlarged scale.
Fig.3 is a longitudinal section through a centre line of the device of Fig.l, shown fitted to a push-tab can (only partially shown) on the same scale as Fig.2, the ring pull having been omitted for clarity.
Fig.4 is a perspective view of a portion of the device of Figs.l-3 shown fitted to a can.
Fig.5 is a partial perspective view from below and one side of a second device according to the invention formed for fitting to a tear-tab can.
Fig.6 is a partial plan view from above of the device shown in Figs.l to 4.
The device shown in Fig.l comprises sealing means indicated generally as 10, a limb shown generally as 20, and gripping means shown generally as 30.
The sealing means comprises a raised portion 12 which, in use of the device, is received in an orifice of the can, a shoulder portion 13 which in use lies on a top surface of the can and a thin laminar tongue 14 which is received in use under the repositioned ring pull portion of an opened push-tab can.
The limb 20 has attachment means comprising a finger 22 disposed so as to point away from the sealing means 10 and by which the device may be clipped to the waist band, belt or pocket of a wearer's clothing. The gripping means 30 comprises a hook shaped part 32 and an indent 34 these being provided so as to be cooperable with various shapes of can bottom surface, those having a deeply recessed bottom having a rim which is received in the recess 34 and those which have a less recessed bottom surface having a shallower rim which, in use, the hook shaped part 32 hooks over.
There is also provided additional gripping means 16 comprising a recess indicated generally as 16a having a curved wall 16b shaped so as to grip, in use, the edge of a circular rim of a can to be sealed.
It will be appreciated that the device shown in Fig.l is in its 'rest' state, the limb 20 being resilient so that to fit the device to a can the gripping means 30 is pulled away from the sealing means 10. The device then grips the can by the resilience of the limb 20 urging the gripping means 30 towards the sealing means 10.
Fig.2 shows the device of Fig.I in longitudinal cross-section. The numerals used in Fig.2 are the same as those used in Fig.l. referring to the same parts of the device.
In Fig.3 the device of Figs.l and 2 is shown fitted to a can (in cross-section). It will be seen that the limb 20 is tensioned having been stretched to grip the can 100. It will also be seen that the finger 22 now lies closer to the body of the limb 20 ready for receiving therebetween the flap of a pocket, a belt, or trouser waist band. The tongue 14 and raised portion 12 of the sealing means, as well as an upper surface 15 of the sealing means have arcuate front edges 14a, 12a and 15a respectively. This is seen also in Figs.4 and 6.
Fig.4 shows how the sealing means cooperates with the ring pull 50 of a push-tab can. The tongue 14 is received under the ring pull and around a stud 52 by which the ring pull 50 is fastened to the can. The concave cut away portion 15a of the upper surface receives the front edge of the ring pull.
Fig. 5 shows a second device according to the invention, with sealing means adapted to fit a tear-tab can. From Fig.5 it will be seen that the sealing means is of a curved segment shape to fit the usual shape of opening in a tear-tab can and comprises a raised portion 12', and a shoulder portion 13'. The remaining parts of the device are substantially the same as that shown in Figs.l to 4.
Various modifications may be made within the scope of the invention. The sealing means may be generally shaped to fit other kinds of can orifice. For example a small lug could be provided in the sealing means of the device shown in Fig.5 at the front edge of the raised portion 12' in order to retain the sealing means in contact with the orifice more easily.
