Description
SPECIFICATION
Container and child resistant closure assembly
This invention relates to a container and child resistant closure assembly.
The invention has as its object to provide an assembly of a container, e.g. a bottle, for drugs, medicines or other possibly dangerous substances and a child resistant closure therefor, the container being readily producible by any blow moulding process and the closure by injection moulding from suitable plastics material. Afurther object of the invention is to provide a container and closure assembly which can be used with a conventional screw cap.
The present invention provides a container and a child resistant closure assembly, the container having a neck portion and the closure having a plug portion adapted to fit within the container neck portion, one of said portions having a projecting annular flange which has at least one break therein and the other of said portions having at least projection thereon which can be passed through said break and engaged with said flange by relative axial and rotational movements of the container and closure to prevent removal of the closure except when said projection is properly aligned with said break.
Preferably, said other portion has a plurality of projections cooperable with corresponding breaks in the flange of said one portion as this helps to stabilise the assembly and disassembly of the closure on and from the container. In order to provide a single normal assembly and disassembly position of the closure relative to the container, one projection and associated break may be made of a size and/or shape different from that of the others.
However, the or each projection may be tapered or chamfered in order to permit the or each projection to be forced past the flange on said on portion to provide rapid closure without the need for alignment of the projections and breaks.
The container may be a bottle having a neck portion and may be formed from any suitable material and in any suitable manner, for example it may be formed from a suitable synthetic plastics material as by any of the well known blow moulding techniques. If desired the neck of the container may be externally screw threaded to receive a conventional screw cap or may be provided with a lip or flange around the mouth thereof which can be engaged by a snap-on cap or closure to enable the container to be used either with the closure of the present assembly and/or with a conventional screw cap or snap-on cap or closure. Alternatively, the closure may be provided with a depending annular skirt to resemble a normal screw cap but without the skirt fulfilling any closure function.However, the skirt may be provided with a continuous or discontinuous lip or bead extending inwardly thereof and arranged to snap over the annular bead normally provided below the screw threads on the neck of a screw-threaded container. In a still further alternative, the closure may be provided with a snap-on cap portion cooperable with the lip or flange around the mouth of container when such is provided. With these alternative arrangements, the need for a separate screw cap or snap-on cap is obviated.
The closure of the assembly may comprise a disc portion from which said plug portion extends and which is of a diameter similar to or larger than the external diameter of the neck of the container so that it can be readily grasped by the hand of a user. The said disc portion may have an arrow or other indication thereon which can be aligned with a similar arrow or indication on the neck of the container to facilitate aligning said projection with said break and may also have wording thereon indicating to a user how to assemble the closure with the container and how to remove the closure from the container.The said plug portion may extend coaxially of said disc portion and may comprise an annular sealing portion adjacent said disc portion which is adapted to make sealing engagement with the internal surface of the neck of the container and an anterior portion of smaller diameter than said annular sealing portion and which has said annular flange or said projection at that end thereof remote from the annular sealing portion.
The present invention will be more particularly described with reference to the accompanying di agrammaticdrawings, in which:

Figures 11 and 12 are side views of alternative closures for the containers of Figures 1 and 6, respectively,
Figures 13 and 14 are side views of further alternative closures for the containers of Figures 1 and 6, respectively, and
Figures 15 and 16 are side views of closures for containers generally similar to those of Figures 1 and 6, respectively, but being of the type to receive a snap-on closure rather than a screw cap.
Referring first to Figures 1 to 5 of the drawings, it will be seen that the assembly illustrated therein comprises a container in the form of a bottle 1 having a neck portion 2 and a closure 3 having a plug portion 4 which can be inserted into the neck portion 2 of the bottle 1.
The neck portion 2 of the bottle 1 has on the internal surface thereof an axially extending radial projection or key 5 the location of which is indicated by an arrow 6 on the external surface of the bottle 1.
Three further but smaller projections or keys 5A are provided with all four projections being generally equiangularly spaced around the inside of the neck portion 2.
The closure 3 comprises a disc portion 7 the periphery 8 of which is knurled, ribbed or otherwise formed so that it can readily be grasped by the hand of a user. The plug portion 4 extends coaxially of the disc portion 7 and comprises an annular sealing portion 9 adjacent the disc portion 7 adapted to make sealing engagement with the internal surface of the neck portion 2 of the bottle 1. Extending coaxially outwardly of the sealing portion 9 is an anterior portion 10 of smaller diameter than the sealing portion 9 and which terminates in an outwardly extending annular flange 11 having a break 12 therein, together with three further but smaller breaks 12A. An arrow 13 on the disc portion 7 indicates the position of the break 12 whilst wording 14 on the disc portion 7 instructs a user how to assemble the closure on and remove it from the neck portion 2 of the bottle 1 (Figure 3).
The breaks 12 and 1 2A are of a size to just receive the corresponding projections or keys 5 and 5A and the plug 4 is of such an axial length that when fully inserted into the neck portion 2 of the bottle 1, the annular flange 11 will be beyond the projections or keys 5 and 5A so that the closure 3 can be rotated relative to the neck portion 2 of the bottle 1 to lock the closure 3 on the bottle 1 and prevent removal of the closure 3 from the bottle 1 until the breaks 12 and 1 2A are again aligned with the respective projections or keys 5 and 5A.The closure 3 is assembled with the neck portion 2 of bottle 1 by aligning the arrow 13 with the arrow 6, inserting the plug portion 4 fully into the neck portion 2 of the bottle 1 so that the annular flange 11 passes beyond the projections or keys 5 and 5A and rotating the closure 3 relative to the bottle 1 to engage the flange 11 with the projections or keys 5 and 5A. The closure is removed from the bottle 1 by first rotating the closure 3 relative to the bottle 1 to align the arrow 13 with the arrow 6 and then pulling the closure 3 axially out of the neck portion 2 of the bottle 1.
The provision offourequianguarlyspaced projections or keys 5 and 5A stabilises the assembly and disassembly of the closure 3 on and from the container 1. However, more than three further projections or keys 5A may be provided or only one or two may be employed instead of three. In order to facilitate rapid assembly of the closure 3 on the container 1, the upper edges of the projections or keys 5 and 5A are tapered or chamfered at 5' and 5A', respectively, to provide a lead-in for the flange 11 when the projections or keys are not aligned with the corresponding breaks 12 and 12A, the flange being compresssed on being forced past the projections or keys and then expanding to engage the undersides of the latter as normal.This rapid closure facility is generally useful but especially for dispensing chemists, for example, in the case of pharmaceutical containers. However, this rapid closure does not detract from the child resistant characteristic of the assembly since the non-tapered undersides of the projections or keys 5 and 5A prevent the closure being pulled from the neck of the container without first aligning the projections or keys with the respective breaks 12 and 12A, unless excess force is used.
A taper of 15 to 20 to the horizontal has been found satisfactory for the chamfered portions 5' and 5A'.
With the rapid closure arrangement, the instructions to the user indicated in Figure 3 could be amended to read "To open - align arrows and pull off. To close insert and press firmly.".
The neck portion 2 of the bottle 1 is externally screw threaded as shown at 15 so that it can be used with a conventional screw cap if desired, this being possible because the bottle 1 is conventional apart from the projections or keys 5 and 5A which are internal of the neck portion 2. Alternatively, the neck portion 2 of the bottle 1 could be provided around its mouth with an outwardly projecting annular lip or flange for engagement by a conventional snap-on cap or closure.
Where the bottle 1 is to contain only dry goods such as pharmaceutical tablets, capsules or powders then it may be closed simply by the closure 3 and in this case the disc portion 7 is preferably of a diameter similar to or greater than the external diameter of the mouth of the neck portion 2. If the bottle 1 is to contain liquids such as liquid medicines then the bottle 1 may be closed both by a closure 3 to provide resistance to tampering by children and by a conventional screw cap to provide sealing against leakage, the disc portion 7 of the closure 3 being of substantially the same diameter as the mouth of the neck portion 2 so that a conventional screw cap can be threaded on the neck portion 2.
Preferably the annular sealing portion 9 of the plug portion 4 is a sufficiently tight frictional fit within the neck portion 2 of the bottle 1 as to provide, when the closure 3 is assembled with the bottle 1, a resistance to rotation of the closure 3 relative to the bottle 1 sufficient to make it difficult for a young child to effect such rotation but not such as to make it too difficult for an adult to effect rotation.
The bottle 1 is preferably formed from a suitable synthetic plastics material as by blow moulding although it can, if desired, be formed from glass or other suitable material. The closure 3 is preferably formed from a suitable synthetic plastics material as by injection moulding.
The embodiment of Figures 6 to 10 is similar to the embodiment of Figures 1 to 5 and like reference numerals have been used to indicate like parts.
The only difference between the embodiment of
Figurs 6 to 10 and the embodiment of Figures 1 to 5 is that in the former embodiment the neck portion 2 of the bottle 1 is provided with an internal, inwardly directed flange 16 having breaks 17 and 17Atherein in place of the projections or keys 5 and 5A, and the plug portion 4 of the closure 3 has projections or keys 18 and 18Athereon in place of the flange 11.As in the previous embodiment, the projections or keys 18 and 18A are adapted just to pass through the corresponding breaks 17 and 17A and the axial length of the plug 4 is such that when the plug 4 is fully inserted in the neck portion 2 of the bottle 1, the projections or keys 18 and 18A will pass beyond the annular flange 16 so that by rotation of the closure 3 relative to the bottle 1, the projections or keys 18 and 18A can be engaged with the annular flange 16.The operation of the assembly of Figures 6 to 10 is exactly the same as that of the assembly of Figures 1 to 5 and again, a rapid closure facility is provided although in this embodiment, the projections or keys 18 and 18A are tapered or chamfered 19 (15" - 20" to the vertical) downwardly from their radially outer edges so as to leave the upper edges square for cooperation with the underside of the flange 16.
Thus, the plug portion 4 of the closure 3 is compressed radially inwardly as the projections or keys 18 and 18A are forced pasttheflange 16, the plug portion then expanding to its normal size when clear of the flange so as to engage the underside thereof.
Turning now to Figures 11 and 12, these show closures 3 basically similar to those of Figures 4 and 9, respectively, but having a depending peripheral skirt 20 formed on the disc portion 7. This skirt 20 makes the closures 3 resemble a normal screw cap although it serves no closure function. However, the skirt 20 provides an enlarged area for grasping by the user and may be knurled, ribbed or serrated to assist gripping. In these two embodiments, the arrow 13 is provided on the skirt 20 rather than on the disc portion 7.
If it is desired for the skirt 20 to effect some closure function, it may be provided internally with an inwardly directed annular bead or flange 21 (Figures 13 and 14) arranged to snap over the annular bead or flange 25 normally provided below the threads on the neck of a screw-threaded container.
In the case of a container fitted with an annular bead or flange at or towards the mouth of the neck portion 2 to receive a snap-on cap, the closure 3 may be provided with a snap-on portion 22 as shown in
Figures 15 and 16 the closures of which otherwise generally correspond to those of Figures 4 and 9, respectively. The snap-on portion 22 is formed on the disc portion 7 of the closure 3 and carries the arrow 13. The snap-on portion 22 comprises a depending peripheral skirt 23 which is slightly outwardly and downwardly flared and which terminates in an inwardly extending flange 24 arranged to snap over and engage the bead or flange (not shown) on the neck of the container.
