Definitions

  • This invention relates to a child resistant closure assemblies comprising a co-operating container and cap in which anti-rotation means must be overcome to enable the cap to be rotated to a predetermined angular orientation on the neck of the container (this position being referred to herein as 'the aligned position') at which one side of the cap (referred to herein as the 'front of the cap') can be pushed off the neck in order to open the container.
  • the cap comprises a top wall and a depending skirt, and a co-operating circumferential bead and a lug are provided which engage to prevent the container from being opened, except at the aligned position.
  • the lug which is on the inside of the skirt at the front of the cap or on the neck of the bottle, can pass though a gap in the circumferential bead which is located on the neck of the container or inside the skirt at the front of the cap, so enabling the front of the cap to be pushed off the neck of the container in order to open the container.
  • Closure assemblies as described above are referred to herein as closure assemblies of the kind described.
  • further engageable means are typically provided on the opposite side of the cap ('the rear of the cap') which disengage from the container neck on opening, so enabling the cap to be completely removed from the container.
  • said further engageable means could be replaced, for example, with hinge means which attach the cap permanently to the container.
  • the present invention relates particularly, but not exclusively, to a closure assembly of the kind described which is the subject of our European patent application published as EP 0500265.
  • the further engageable means are provided on the rear of the cap and which disengage from the container neck on opening, to enable the cap to be completely removed from the container, and the skirt of the cap is connected by a number of breakable webs to a circumferentially extending tear-off band which in its turn is joined by further breakable webs to a continuous circumferentially extending captive band on the neck of the container.
  • Lugs on the captive band and on the neck of the container engage to provide the anti-rotation means of the closure assembly.
  • the anti-rotation means prevent the cap from being rotated to the aligned position until the captive band has been disconnected from the cap by removal of the tear-off band, and removal of the band is tamper-evident.
  • Provision of the anti-rotation means in closure assemblies of the kind described is an additional child-resistant safety feature to that of arranging for the cap to be removable only in the aligned position.
  • a child-resistant closure assembly of the kind described is provided with separable means attached to the cap of the assembly by way of a frangible connection, the assembly comprising detent means on the separable means and on the neck of the container of the assembly, surfaces of the detent means being engageable in the cap aligned position to resist the cap being pushed off the neck of the container until the frangible connection has been broken, said surfaces being engageable in the cap aligned position.
  • breaking of the frangible connection is arranged to be tamper-evident. It may, for example, involve the removal of a tear-off band, the absence of which would be clearly visible.
  • Said separable means may itself comprise such a tear-off band, but most preferably comprises a band such as a captive band which is spaced from the cap by a tear-off band.
  • the detent means on the separable means preferably comprises a surface of the separable means.
  • the detent means on the neck of the container conveniently comprises a projection. Most preferably a surface of the projection is obliquely angled relative to the direction of capping of the container, in order to facilitate passage of the separable means over the projection without damaging the frangible connection of the separable means.
  • the detent means on the neck of the container comprises a projection in the form of a rib which extends around the neck through less than a quarter of the neck circumference.
  • the detent means on the neck may comprise a plurality of projections disposed around the neck. Where the neck of the container is injection moulded, the detent means on the neck is preferably provided on a circumferential bead on the neck.
  • the detent means on the neck of the container is desirably located in a gap between the ends of the tear-off band when capping has occurred in the aligned position.
  • the tear-off band is preferably arranged to deform over the detent means without damaging its connection or connections to other parts of the closure assembly.
  • the closure assembly of Figure 1 comprises an injection-moulded container 1, a cap 2 having a skirt portion 3, and a captive band 4 attached via a tamper-evident tear-off band 5 and a pair of frangible connections 6 and 7 to the skirt portion 3.
  • Arrows 8 on the skirt 3 and 9 on the container 1 show that the cap has been put on in the aligned position.
  • the container 1 may be blow-moulded, at least in part.
  • a tab 10 on one end of the tear-off band 5 provides a grip for the fingers in removing the band.
  • the projection 11 comprises a rib which extends around the neck of the container 1 through less than a quarter of the neck circumference.
  • Figure 3 shows the closure assembly after the tear-off band 5 has been torn away and the cap removed, leaving the captive band 4 on the neck.
  • a lug on the cap normally engages beneath circumferential bead 13 on the container neck to prevent removal of the cap, except in the aligned position in which the lug can pass through the gap 14 in the bead.
  • the term 'captive band' is normally used to refer to a band which passes continuously around the neck of a container, but which is left behind after removal of a tear-off band. In this instance, after having been left behind, the captive band has no further role, and is free to fall off the neck of the container should the container be inverted.
  • Figure 4 shows the neck finish when the captive band 4 has also been removed.
  • Lugs 12 on the neck which are normally covered by the captive band, interengage with lugs on the inside surface of the captive band to form the anti-rotation means of the closure assembly.
  • the projection 11 in one embodiment has sides which are substantially rectangular.
  • the projection in a second embodiment, shown in Figures 8 and 9, is substantially wedge-shaped in vertical cross section, so as to present an obliquely angled surface 11b to the tear-off band 5 and the captive band 4 during capping, so that these can pass easily over the projection without damaging the frangible connections 6 and 7.
  • FIGs 12 and 13 a container 101 of an injection-moulded closure assembly is illustrated thereby, the container cap, tear-off band and captive band having been removed for reasons of clarity.
  • the container 101 may be blow-moulded, at least in part.
  • the container 101 is provided with detent means on the neck of the container, comprising three equi-spaced projections 111 disposed in a ring which is coaxial about the central longitudinal axis 25 of the container.
  • a single gap 114 is provided in the circumferential bead 113.
  • One of the projections 111 is aligned with the gap 114 when capping takes place.
  • the non-illustrated container cap, the tear-off band and the captive band of the assembly are of substantially the same form as cap 2, tear-off band 5 and captive band 4 of Figures 1 and 2.
  • the lugs 111 serve to prevent the captive band (not shown, but corresponding to captive band 4 of Figure 1) from falling off if the container, when opened, is inverted.
  • the plurality of spaced-apart lugs 111 serve to increase resistance to the container cap (not shown, but corresponding to cap 2 of Figure 1) being removed, particularly in the cap aligned position, when the tear-off band is present.
  • a single lug 11 offers resistance at a single, localised position, whereas the lugs 111 each offer substantially the same resistance, but at a number of spaced-apart positions.
  • the spaced-apart lugs 111 assist machine-capping, as the cap is centralised as it sits on the three lugs 111, before being pushed down into place.
  • any of the features disclosed herein may be added to, or substituted for other features.
  • the single lug 11 of Figures 10 and 11 could be replaced by a plurality of lugs, as in Figure 12.
  • containers of increased neck size may employ more than three lugs corresponding to lugs 111.
  • lug dimensions, particularly width may vary according to requirements.
