Definitions
- the present invention relates to a plastics material cap for closing a container and in particular, but not exclusively a closure cap for a screw top bottle.
- a ring extending down from the inside of the top of the cap can be used.
- the material of the cap cannot be as flexible as that of a liner, therefore the precision of the moulding of the cap is critical.
- the force with which the cap is applied that is to say the torque applied by a capping machine or capper, needs to be higher than is the case with a liner in the cap. Increasing the torque can itself introduce unreliability.
- an anti-tamper band at the bottom of the skirt of the cap. This is connected to the cap by frangible links extending from the skirt to the band.
- the anti-tamper band includes a continuous internal ridge, which rides over and engages under a complementary ridge on the bottle, a considerable amount of force and torque must be transmitted by the links to the band.
- the links must be of a certain size. However, making the links large enough to force the ridges over each other can make them too strong to enable easy breaking of the anti-tamper band from the skirt on opening of the bottle.
- the object of the invention is to provide an improved closure cap.
- a plastics material cap for closing a container, the cap comprising: • a top and a skirt;
- the sealing means including:
- the first annular sealing member is arranged to abut the inside of a neck of the container and the second annular sealing member is arranged to abut the distal end of the neck of the container.
- the first and second members have a common root, whereby abutment of the distal end of the container with second member tends to rotate the first member into firmer contact with the inside of the neck.
- the first and second annular sealing members will be lips dimensioned for slight deflection on sealing abutment with container, the lips preferably being of substantially the same shape
- a third annular sealing member is provided for abutment with the outside of the neck of the container.
- the means for holding the cap in position can be a snap fit of a feature on the skirt onto a feature on the neck; preferably the means for holding the cap in its sealing position is a screw thread in the cap for co-operation with a screw thread on the bottle.
- the skirt will be provided with an anti-tamper band.
- a plastics material cap for closing a container comprising:
- the tongues are interconnected by invert V fold members.
- the tongues have ribs on their radially outer surfaces for limiting the radial movement of tongues on fitting of the cap to the container.
- a ridge is provided on the inside surface of the skirt for co-operating with the ribs in limiting the radial movement of the tongues.
- the cap holding means is a screw thread in the skirt for threadedly engaging a complementary thread on the container.
- the sealing means is means integrally formed with the top on its inside for sealing the cap to the container, the sealing means including: • a first annular sealing member and
- Figure 1 is a partially broken away perspective view from below off a closure cap of the invention
- Figure 2 is a central cross-sectional side view of the cap of Figure 1;
- Figure 2A is a scrap view on a larger scale of the sealing detail at Y in Figure 2;
- Figure 2B is a scrap view on a larger scale of the anti-tamper detail at Y in Figure 2;
- Figure 3 is a cross-sectional view on the same scale as Figure 2B through an anti-tamper tongue;
- Figure 4 is a cross-sectional view through the cap when fitted to a bottle.
- the injection moulded, plastics material cap 1 there- shown for a screw top bottle has a top and a skirt with an anti-tamper band 2 connected to the skirt at a tear-of line by links 3.
- a depending annular ridge 10 is provided on the inside of the top of the cap. Its inside diameter is such that it abuts and seals on the outside diameter of the distal end of neck of the bottle, as shown in Figure 4. Also on the inside of the cap, inside the ridge 10, another annular feature is moulded, with a forked cross-section. This has an inner - that is smaller diameter - limb 12 which extends generally downwards with an outwards bias, and an outer limb 13 which extends generally outwards with downwards bias. The inner limb is dimensioned to fit inside the mouth at the neck of the bottle, sealingly engaging it, whilst the outer limb is dimensioned to abut the end of the neck, also sealingly engaging it when the cap is screwed tight.
- tongues 21 are provided on the inside of the anti-tamper band. Adjacent ones of these are interconnected by webs 20 in the form of invert V folds. The folds extend up and out (radially) from the tongues. The latter have ribs 22 on their outer faces. Above the proximal ends of the tongues, a ridge 23 is provided around the inside of the band, at a position such that the ribs abut it when the tongues are pushed up, as on screwing of the cap onto the bottle.
- the combined action of the folded webs 20 and the resilience of the tongues 21 themselves causes them to spring inwards when pushed outwards during fitting of the cap to the bottle as described below.
- the abutment of the ribs 22 against the ridge 23 limits the outwards movement of the tongues.
- the cap is moulded integrally with the cap as such connected to the anti- tamper band 2 by the links 3.
- the cap On filling of a bottle, the cap is placed on the bottle's neck by a capping machine. Inside the skirt of the cap, that is above the band, the cap has screw formations complementary to the screw formations 40 on the neck of the bottle. Below these latter, the neck has an anti-tamper ridge 41.
- the cap is screwed on and tightened by a capper.
- the tongues come into abutment with the ridge 41, which urges them outwards.
- the distal ends of the tongues pass the ridge, they spring in underneath it.
- the arrangement of the tongues at an upwards angle and the folds between them enables the tongues to be deflected with a relatively low torque applied to the cap by the capper.
- abutment of the ribs 22 against the ridge 23 avoids excessive deformation of the tongues for any reason.
- the tongues clear the ridge 41 they are not excessively stressed and readily spring back to engage beneath the ridge 41.
- the bottle is used for hot-fill, that is to say the contents are filled when hot, a slight vacuum may develop in the bottle.
- the outer lip 13 will have a greater pressure on its outside than its inside. This pressure differential tends to urge the lip 13 into sealing engagement with the end of the bottle.
- the inner lip will have a pressure differential across it urging into contact with the neck of the bottle.
- the ridge 10 provides an additional seal with the neck of the bottle.
- the cap On opening of the bottle, the cap is unscrewed.
- the tongues engaged under the ridge 41 hold the anti-tamper band tightly on the bottle, so that only a small unscrewing movement of the cap is needed to rupture the links 3 at the tear off line.
- any attempted tampering prior to purchase can be seen by inspection of the cap for separation of the band from the cap proper
