Abstract

A tamper-evident closure ( 10) is provided and comprises a base (20) and a lid (30). The base has a tamper-evident feature (23) frangibly connected thereto. The lid has retention means (33) which upon first opening of the closure cause the tamper-evident feature to be released from the base and thereafter retain the feature on the lid.

Description

TAMPER EVIDENT CLOSURE
The present invention relates generally to a closure and particularly to a tamper- evident closure in which after the closure the closure has been opened for the first time there is visible evidence.
It is known to provide closures with a variety of different tamper-evident mechanisms including tamper-evident bands which are separated from the main closure body upon opening.
According to a first aspect of the present invention there is provided a tamper-evident closure compromising a body having a fixed part and a movable part, one of the parts having a tamper-evident feature and frangibly connected thereto and the other part having a retention feature, in which upon first opening the retention feature causes the tamper-evident feature to be released and thereafter retains the feature.
The present invention is based on the idea that on first opening a tamper-indicating feature on one part of a closure should be caused to break away by a retention feature on a different part of the closure; and thereafter the tamper-evident feature is retained by the retention feature. Accordingly, although the tamper-evident feature is released from one part of the closure it is retained on a different part.
The fixed part may comprise a base and the movable part comprises a lid. Other combinations of parts, and further parts such as spouts, are possible.
The parts may be connected together by a hinge, such as a snap hinge.
The closure may be moulded in the open position and upon first closing the retention feature is arranged to engage the tamper-evident feature.
Following first opening the tamper-evident feature may be at least partly concealed by the retention feature. This, gives additional evidence that the closure has been opened.
The retention feature may comprise a hook or the like. A hook structure can be used both to pull off a tamper-evident feature and if suitably shaped the feature can be clipped under the hook. The tαmper-evident feature may comprise one or more tabs, bands or the like.
The or each tab may be frangibly connected to the part by one or more frangible bridges or weakened portions.
The closure may be adapted for one-handed opening.
The movable part may comprise a pushing zone. In one embodiment two tamper- evident tabs are positioned on either side of a central pushing zone.
The closure may comprise a tamper-evident cover for an inner cap. In some embodiments the closure is a stand-alone structure and in others it is fitted onto or over a further closure/cap structure.
The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a perspective view of a closure formed according to the present invention shown in an open, as-moulded position prior to first closing;
Figure 2 is a front elevation of the closure of Figure 1 shown in an initially closed position;
Figure 3 is a side elevation of the closure of Figures 1 and 2 shown part way through a first opening operation; and
Figure 4 is a perspective view of the closure of Figures 1 to 3 shown following first opening.
Referring first to Figure 1 there is shown a closure generally indicated 10.
The closure 10 comprises a base 20 and a lid 30.
The base 20 comprises a generally cylindrical side skirt 21. One end of the skirt 21 fits onto a container neck 40, in this embodiment using co-operating screw thread formations (not shown) although other engagement features such as snap beads and the like could be used. At the other end of the skirt 21 α peripheral rim 22 projects radially inwardly. The rim 21 is continuous except in the region of a hinge 50 described in more detail below.
Opposite the hinge 50 the rim 21 carries two spaced, tamper-evident tabs 23 each of which is frangibly connected to two spaced, upstanding supporting posts 24 which are fixedly attached to the rim 22. This gives a generally upturned u-shape configuration.
The hinge 50 is provided as part of an inner pouring cap generally indicated 60. The cap 60 comprises a spout 61 and a lid 62 which are joined together by the hinge 50. The spout 61 is held within the base 20 but projects beyond the rim 21. The cap 61 fits within the lid 30 and includes a depending annular sealing ring 63 which seals within the orifice of the spout 61.
The lid 30 comprises a circular top plate 31 from which depends two arcuate side wall portions 32 which extend from the region of the hinge 50 and terminate at the point at which two spaced hooks 33 depend. The hooks are generally J-shape and accordingly comprise a back wall 33a and a curved front wall 33b.
Between the hooks 33 an arcuate pressing portion 34 depends from the lid 31 and includes a plurality of circumferential ribs 35 the purpose of which will be described in more* detail below.
Figure 1 shows the closure 10 in an as-moulded condition in which the hooks 33 do not engage the tabs 23. When the closure 10 is first closed prior to use the hooks 33 can pass under the tabs 23 because the curved front walls 33b can gently push on the tabs 23 without breaking them away from the posts 24. When the closure is in the fully closed position the free end of the curved front walls 33b sit below the tabs 23 as shown in Figure 2 so that the tabs 23 are visible.
Referring how to Figure 3, when the closure 10 is opened for the first time a user presses on the pressing portion. The ribs 35 help the user to push on the lid and allows the closure to be opened one-handed. The hooks 33 engage under the tabs 23 between the posts 24.
Continued opening results in the tabs 23 being ripped off the post 24. The posts 24 stay
■ on the base 20. The hooks 33 are shaped so that the tabs 23 fit tightly within the lower retaining portion so that the tabs 23 cannot fall out, as shown in Figure 4. The opening defined by the curved front wall 33b is narrower than the thickness of the tabs 23. Accordingly when the lid is lifted the tabs cause the wall 33b to deform and then snap back into place when the tabs fit into the bottom of the hooks so that they are locked in position. In an alternative embodiment (not shown) the posts are pulled off the rim 22 with the tabs 23.
It will be seen that following first opening the tabs 23 are concealed by the hooks 33 and this will be the case even when the closure is re-closed as the hooks 33 pass between the post 24.
In this embodiment, therefore, the hooks 33 serve to separate the tamper-evident feature, retain the tamper-evident feature and conceal the tamper-evident feature. The tamper-evident feature is transferred from one part of the closure to another but at all times is held on the closure.
