DISPLAY SUPPORTFOR SUSPENDEDPACKAGES HAVING SPACERDEVICE
This invention relates to packaging arrays, and more particularly to a package and display means for feeding packaged products to a consumer take-off point.
In supermarkets and other self-service stores articles are frequently sold in hanging packages adapted to hang from supports in a packaging display. In a common practice, a number of the packages are threaded on a horizontal elongate support in a row forming an array, allowing the customer to remove the package nearest to the end of the support. A display stand may have a large number of such supports and packages. Although by no means essential, many of such packages have at least one wall or a portion thereof formed from a transparent plastics film. Typical of such display packages are blister packs, clam-shell packs, and similar designs. These packages usually incorporate a piece of card or stiff plastics film as a backing or spine, the card having a hole adjacent one edge region thereof, by which the package can be suspended from a display stand. Hanging packages and arrays of the type described are very convenient and have been widely adopted, even for small items, which are often packed in large hanging packages to reduce the risk of pilferage. They do, however, have several disadvantages. Firstly, the blister packs and clam-shell packs are often of irregular shape, for example a blister pack usually comprises a
flat card having a dome-shaped central region of vacuum- formed transparent plastic film containing the article. When a number of these packs are threaded on an elongate support they tend to "bunch-up" due to their irregular shape, giving an untidy and unsightly appearance.
Moreover, as the nearest packages are removed from the elongate support, the remaining packages, which are further away from the customer, are more difficult to see on the display stand and may be overlooked. The elongate supports are often quite long, up to 60 cm in length, and therefore the last few packages are also quite difficult to remove.
The present invention provides a novel combination of a display support and packages threaded thereon, in which, as a package is removed from a free end of the support, another takes its place.
The invention also provides a hanging package, and an attachment device for a display package, shaped so as to reduce the "bunching-up" problem. The invention further provides a display support having means for moving packages threaded thereon towards a free end of the support.
According to a first aspect of the present invention there is provided a packaging array comprising an elongate display support and a plurality of hanging display packages suspended therefrom, the support having a fixed end and a free end and having (i) a downwardly inclined section between its ends or (ii) means for
moving display packages towards its free end, or both, and the display packages having suspension means whereby they are threadedly engaged with the elongate display support and spacer means arranged adjacent to the suspension means having a depth comparable to or greater than the greatest depth of the display package.
In another aspect of the invention there is provided an attachment device for a hanging package of the type adapted to be suspended from an elongate display support, the package having suspension means whereby the package can be threadedly engaged with an elongate display support, the attachment device comprising spacer means which, when the device is attached to the package, is arranged adjacent to the suspension means and which has a depth comparable with or greater than the greatest depth of the display package.
In a further aspect of the invention there is provided an attachment device for a hanging package, the device comprising suspension means whereby the package can be threadedly engaged with an elongate display support, and spacer means arranged adjacent to the suspension means, the spacer means having a depth comparable with or greater than the greatest depth of the display package. In a still further aspect of the invention there is provided a display package of the type adapted to be suspended from an elongate display support, the package having suspension means whereby the package can be
threadedly engaged with an elongate display support, and comprising spacer means arranged above or surrounding the suspension means, the spacer means having a depth comparable with or equal to the greatest depth of the display package.
In a yet further aspect of the invention there is provided a packaging array comprising an elongate display support and a plurality of hanging display packages suspended in a row therefrom, the support having a fixed end and a free end, and a push means or cursor mounted on the support and adapted to urge the row of packages in the direction of the free end of the support by applying pressure to a rear end package of the row over an area encompassing or adjacent to the point of greatest depth of the package, the free end of the support being provided with means for retaining the row of packages on the support whilst permitting the front end package to be manually removed by a consumer.
The elongate display support may comprise a single elongate rod or strip, having a fixed end adapted to be secured to a wall or display stand, and a free end with an end portion adapted to prevent the hanging packages from falling off the support, but allowing the hanging packages to be sequentially removed therefrom. For greater strength, and to improve the stability of the packages in a vertical plane, it is, however, preferred to use a support comprising two parallel rods or tubes or a single U-shaped rod or tube having elongate
arms. Where a U-shaped rod is used, the extremities of the arms are preferably anchored to the wall or display stand to form the fixed end of the elongate support. The elongate support may be formed from metal or plastic materials, or a combination thereof. The elongate support may be of any suitable length, but is usually greater than lOcms in length, and preferably from 10 to 60 cms in length, more preferably from 15 to 60 cms in length. The end portion of the elongate display support can be adapted to retain the display packages in any convenient way, for example it may have a bulbous end, or the end may be hook-shaped and up-turned sufficiently to prevent the hanging packages from sliding off the support, or the end may be provided with a pivotable retaining device. A generally hook-shaped elongate support is preferred for use in the invention.
In one preferred embodiment the elongate display support has a downwardly inclined section between its fixed and free ends whereby the hanging packages can slide under gravity along the support towards the free end. This is only possible to arrange consistently if "bunching-up" can be avoided, as will be explained hereinafter. One way of minimising the "bunching-up" problem is to use regularly shaped packages so shaped that when hanging in a row on a downwardly inclined support, with adjacent packages in contact with each other, the contact
point or points of the packages are sufficiently close to the suspension means for each of the packages to hang substantially vertically from the support.
Accordingly, in another aspect the invention provides a packaging array comprising an elongate display support and a plurality of hanging regularly shaped display packages suspended therefrom in a row and in contact with each other, the support having a fixed end and a free end and having a downwardly inclined section between its ends, the display packages having suspension means whereby they are threadedly engaged with the elongate display support, and the contact point or points of the packages being sufficiently close to the suspension means for each of the packages to hang substantially vertically from the support.
In another preferred embodiment the elongate display support is provided with means for moving the hanging packages towards its free end, which means may, for example, be spring activated or comprise an elastic member. Such a support is in itself novel and is included within the invention.
Accordingly, a further aspect of the invention provides an elongate display support adapted to receive a plurality of hanging display packages threaded thereon in a row, the support having a first end adapted to be fixedly secured to a wall of other vertical surface and a second free end provided with means for retaining the row of packages on the support whilst permitting the
front end package of the row to be manually removed by a consumer, and a push means or cursor mounted on the support and adapted to urge the row of packages in the direction of the free end of the support by applying pressure to a rear end package of the row.
By way of example, the support may have a push means or cursor threaded thereon, the push means or cursor carrying a roll spring whose free end is attached to the free end of the support so that the push means or cursor is urged by the roll spring in the direction of the free end. When hanging packages are threaded onto the support the push means or cursor is moved back towards the fixed end but continues to urge the packages towards the free end under the action of the spring. The roll spring can, in appropriate circumstances, be replaced by a tension coil spring or an elastic member, or a weight and pulley as appropriate. The surface of the elongate support is preferably smooth to allow for low-friction travel of the packages therealong. In another preferred embodiment of the invention the elongate display support is provided both with a downwardly inclined section between its fixed and free ends and with a push means or cursor mounted on the support, so that the packages are urged both by a component of gravity and by the push means or cursor towards the free end of the elongate support.
The hanging display packages can be regularly or irregularly shaped, but in certain circumstances it may
be preferred to use a package whose major surfaces at least are substantially parallel. The package can, for example, comprise a backing or spine forming one major surface and a moulded transparent container forming the other major surface, the card or spine and the container being joined at their edge regions to enclose the packaged article. Other designs are of course possible. The suspension means can be, for example, a hole or hook, of a size sufficient to allow the package to be threaded on the elongate support and to allow the package free movement therealong. The hole or hook is preferably situated adjacent the top edge of the package for example at a point that is from 75% to 90% of the height of the package, or the height of the package plus attachment device if present. It may be formed in the package itself, or in the attachment device if present, or both. The hole or hook may be circular, where a single rod- shaped support is used, but is preferably elongate, to permit the use of two parallel rods, or a U-shaped rod, as the support. Where an attachment device is used, this is preferably provided with a hole or hook which, in use, is in register with a similarly sized hole or hook adjacent the top edge of the package.
The suspension means desirably provides a low friction surface in contact with the elongate support in order to provide smooth and easy movement of the package along the elongate support. The wall of the package or attachment device adjacent the hole or hook is preferably
of smooth shape, for example contoured or rounded, so as to minimise any impediment to the movement of the package along the elongate support.
The spacer means may be provided on the hanging package, or on the attachment device, or both. In certain circumstances the spacer means may be a wholly separate item, but this is not usually preferred. Where the spacer means is provided on the package, this may take the form of a moulded or vacuum-formed shape above, below, or surrounding the hole or hook or other suspension means. Where the spacer means is provided on the attachment device this may be provided by the walls of the device itself, or by a specially moulded wider portion of the device. In order to avoid "bunching-up" it is important that the spacer means be relatively close to the suspension means such that when adjacent spacers are touching, the packages hang substantially vertically downwards. The spacer means is usually situated at a point at least 50%, preferably 60%, more preferably 75% and most preferably 90% or more of the height of the package.
The minimum depth or thickness of the spacer means is dependent on the depth or thickness of the hanging packages and their shape. In this specification the depth of the package or spacer means is measured in a direction normal to the largest plane of the package. Normally the depth of the spacer means is at least as great as that of the package, although with certain
irregularly shaped packages it may be possible to use a spacer means having a depth slightly less than the depth of the package, for example the spacer means may have a depth of only 80% or 90% of the depth of the package. Preferably, however, the spacer means is at least as deep as the greatest depth of the package and for example it may be from 100% up to around 120% of the depth of the package or greater.
In one embodiment of the present invention there is provided an attachment device comprising the spacer means and optionally also the suspension means. Such an attachment device is particularly convenient in that it can enable existing hanging packages to be used in the invention without substantial further modification. The attachment device is preferably clipped, clamped, fastened or secured in any suitable way to, for example, the top edge of the hanging package. The device can, for example, comprise a clam-shell arrangement with a "live" hinge and integral fastening means to fasten the two halves of the clam-shell together around the top edge of the package. A hole or holes for the fastening means to pass through may be provided toward the top edge of the package, or the fastening means may comprise piercing means to produce a suitable hole or holes in the package. Where the attachment device also comprises the suspension means, this may be provided for example by holes with rounded edges in each half of the clam-shell
arrangement which are in register when the clam-shell is closed.
A particular advantage of the use of a separate attachment device is that the device may incorporate further features useful to the store, for example, it may carry information about the product, in writing or by colour coding, or it may comprise a security device, for example a magnetic strip detectable by a store detection system. The attachment device may remain secured to the package, and be disposed of with the package, or it may be detached by a store assistant at the point of sale and re-used.
Various embodiments of the invention will now be described with reference to and as illustrated in the accompanying Drawings in which:

Referring now to Figures 1 to 3 the attachment device illustrated generally at 1 comprises two clam¬ shell halves 2,3 joined by a "live" hinge 4. The clam¬ shell halves are provided with elongate holes 5,6 with rounded shoulders 7,8. Internal pillars 9,10 and 11,12 have telescoping ends 13,14 and 15,16 by which the two clam-shell halves 2,3 can be firmly fastened together. In Figure 2 there is shown a card 17 of a typical blister
pack, provided with holes 18,19 for the reception respectively of pillars 9,10 and 11,12. Figure 2 shows the placing of the attachment device over the card 17 and it can be seen from Figure 3 that when the clam-shell device is clamped in place the holes 5,6 in the clam¬ shell device and hole 20 in the card 17 are all in register.
Referring now to Figure 4 there is shown an assembly of hanging packages according to the invention threaded upon a display hook 21. The display hook has a downwardly inclined section 22 and an up-turned hook- shaped end 23. It can be seen that because of the low friction surfaces 7,8 of the attachment device 1 the packages are free to slide along the downwardly inclined section 22 of the display hook 21 until they reach the up-turned end 23. The depths of the attachment devices 1 are substantially the same as the depths of the blister packages 24 so that the packs hang substantially vertically downwardly from the display 21 and bunching is thereby avoided. The packages can easily be removed sequentially by lifting in the direction of the arrow as shown. Figure 5 shows an alternative design of attachment device for use with a wider blister pack incorporating a wider portion 25 which is moulded into one of the halves of the clam-shell to accommodate the extra width of the blister packs.
Referring now to Figure 6, the display hook illustrated generally at 30 comprises a U-shaped rod 31
having elongate arms 32,33 joined by an upturned section 34 forming a hook at the free end of the U-shaped arms. A slider or cursor 35 is threaded on to the U-shaped arms and is freely moveable therealong. A roll spring 36 has one end 37 attached to the hook end of the display hook and is carried upon a spindle 38 mounted crosswise on the slider 35. A portion of the slider or cursor 35 is broken away in the figure to show the roll spring in position upon the spindle. In operation as packages are threaded upon the display hook the slider or cursor is pushed to the rear of the hook, but still exerts pressure by means of the spring to push the packages towards the free end of the hook. In this embodiment the display hook may also have a downwardly inclined section, but this is not essential.
The display hook 70 of Figures 7a and 7b is similar in shape to that of Figure 6 except that it comprises an elongate metal strip 71 with an up-turned rounded end 72. The metal strip 71 has a plastics friction-reducing cover 73 and is fixed at its rear end to a wall bracket 74. A slidable cursor 75 is mounted on the display hook and carries a loosely coiled spring 76 which projected through an opening 77 in the cursor and is led underneath the metal strip 71 to a fixing point 78 adjacent the up¬ turned end 72. The spring 76 operates in the same way to urge the cursor 75 in the direction of the up-turned end 72.
Referring now to Figure 8, there is shown a first novel hanging package according to the invention. The package, illustrated generally at 40, is a blister pack which comprises a vacuum formed transparent plastic film 41 which is laminated to a backing card 42. Elongate holes 43 and 44 in the film and card respectively are in register when the two parts are laminated together. A first vacuum formed cavity in the film 45 is adapted to receive the packaged product and a second vacuum formed cavity 46, arranged above the hole 43, comprises the spacer means for the package. Figure 9 shows a plurality of blister packs according to Figure 8 assembled upon a display hook 47 as previously described. It will be seen that the horizontal depth or thickness of the spacer means 46 effectively prevents the packages from bunching. A second novel hanging package according to the invention is shown in Figure 10, in which there is illustrated a clam-shell pack comprising a vacuum formed transparent plastic film 50 which is in two parts 51, 52 joined by a "live" hinge 53. A card insert 54 fits between the two halves of the clam-shell formed by the parts 51 and 52 of the film. In the assembled pack, elongate holes 55, 56 and 57 are in register so that the pack can be suspended from a display hook. Vacuum formed cavities 58, 59 in respectively parts 51, 52 form a transparent product retaining cavity in the assembled package. The card insert 54 forms a picture frame around this cavity. Vacuum formed parts 60, 61, in clam-shell
parts 51 and 52 cooperate to form the spacer means 62 for the hanging package (see Figure 11) .
An array comprising a plurality of packages according to Figure 10 on a display hook 63 is shown in Figure 11. It can be seen once again the horizontal depth or' thickness of the spacer means 62 prevents bunching up of the packages.
Figure 12 shows a packaging array according to the invention in which a novel display hook of the invention is used with an array of conventional hanging display packages. The packages 80 each comprise a card 81 provided with a hole from which the package can be suspended, and a vacuum-formed transparent plastics body 82 in which the product is displayed. The display hook 83 has an up-turned free end 84 and is fixed to a wall- mounted bracket 85. A cursor 86, is urged by a roll spring 87 in the direction of the up-turned end 84, in a manner similar to that described in connection with Figures 6, 7a and 7b. However in this case the cursor has a cranked bend 88 such that the force applied to the end package by the cursor plate -89 is applied at is point of maximum depth. In this way the force is evenly transferred by each package and "bunching-up" is avoided. If the force were to be applied solely to the top region of the package adjacent the suspension point, a turning moment is created, and tilting of the package and "bunching-up" would be very likely to occur.
Instead of the spring-operated cursor, it is possible to provide the display hook with a downwardly inclined section between its fixed and free ends, whereby the packages are urged under gravity towards the free end. This method can be operated for example with regularly-shaped flat-faced packages which can hang substantially vertically downwards.
