BACKGROUND OF THE INVENTION Strip merchandisers are widely used throughout the retail trade to take advantage of cross-selling opportunities between products and to create impulse purchases without using valuable shelf space. They are also useful to display a plurality of discrete articles in a prominent manner using the least amount of available display area.

Examples of such strip merchandisers are described in US Patents US 4,483, 502 & US 4,546, 943.

As can be seen in the art, strip merchandisers are provided with a plurality of longitudinally spaced hooks upon which product may be hung.

Many items are sold in packaging, having a convenient tab in which a suitable hole or slot can be made enabling the products to be readily displayed on a strip merchandiser. Unfortunately this is not always possible or convenient, either the packaging size or shape does not easily take a punched hole or slot, as in cosmetics sachets for example, or the product does not usually have any additional packaging, as in a paperback book. It is possible to attach tabs having slots therein to each item. Tabs of this type are described in many Patent publications including WO00/26109 ; US5,542, 634; US5, 020,761 ; and US4, 890, 809 but these can have their own disadvantages. The adhesive on the tab may not always attach or remain attached to the product. For example the package may be a sachet which has been sealed by heat sealing or the like so that the edges of the sachet are no. longer flat and do not readily adhere to the tab. In other cases, the adhesive may damage the product, for example the cover of a book. It will also be apparent to one skilled in the art that these tabs invariably are applied manually and the expense through added labour and material costs is not attractive. The current requirement from many retailers is for products to be delivered by the manufactures/wholesalers already attached to a strip merchandiser. If product is damage or detached from a strip then there is every chance that the whole strip or event the batch may be rejected.

It is one object of the present invention to provide a display device akin to a strip merchandiser whereby the disadvantages described above may be overcome.

SUMMARY OF THE INVENTION According to one aspect of the present invention a display device comprises an elongate strip of sheet material having a plurality of product carrying pockets each pocket being provided with a pair of laterally spaced front sections in a plane substantially parallel to the plane of an adjacent rear section of the elongate strip, each front section being attached to said rear section of the elongate strip, at or adjacent an upper edge thereof, by means of an upper bridge portion, a further attachment between a further section of the elongate strip and the front portions is provided by at least one lower bridge intermediate the front portions and which is attached thereto at or adjacent the lower edges thereof and the pockets being arranged one above another so that the front sections of an upper pocket are in integral and coplanar attachment with the rear sections of a pocket immediately below.

It will be seen that products may be held in the space defined by at least the front and rear sections and the at least one lower bridge portion.

For additional security and to prevent accidental removal of products from the pockets one or both of the front portions, may be provided with detent means to firmly engage the product when located in the pocket. Such detent means is preferably provided in both front portions and may each comprise a tab adapted to abut either side of the products. The tab is preferably integral with the front portion.

The upper and lower bridge portions are preferably integral with respective areas of the front and rear sections and may provided by part of the respective section thereof or in one embodiment are provided by such parts which extend therebetween substantially at right angles to the substantially parallel planes, which parts being defined by fold-lines adapted to allow the bridge portions to remain substantially at rights angle to the parallel planes at least during use.

The display device may be provided with any convenient number of pockets which may be arranged continuously in stepped arrangement as described above. For convenience the display device is preferably provided with means to enable the loaded display device to be folded at least once along its length so that the loaded display device may be conveniently packed in a suitable carton or other container for shipment. In one embodiment the stepped arrangement is interrupted by an intermediate flat section of elongate strip which flat section carries means to facilitate a fold. Such means to facilitate the fold may be provided by a score-line, perforations or any other convenient means. Where perforations are provided that strip may also be readily split so as to produce a series of shorter strips, which may suit a particular retailer or to remove a section of display device from which all the product has been purchased.

Preferably the display device is provided at its head with means to attach the display device to other display apparatus. Such means may be provided by a hole or slot or self-adhesive tape or by any other convenient means. Where the display device is capable of being split, further attachment means may be provided below the perforations in the intermediate flat section.

It is a particular advantage of the present invention that the display device may be manufactured from a single sheet of material which sheet is provided with a series of cuts and fold lines which form the various sections and portions of the pockets.

According to another aspect of the present invention a blank for a display device of the type having a plurality of product carrying pockets comprises an elongate sheet of suitable material having a pair of substantially parallel spaced lines of longitudinal cuts running substantially centrally along at least one section of the sheet material, a second pair of substantially parallel spaced lines of longitudinal cuts running one each intermediate the first pair of lines and a respective edge of the sheet, adjacent cuts in the first and second lines being joined by a connecting cut between the leading and of a respective cut in the second pair of lines and the trailing end of a respective cut in the first pair of lines so that each area of sheet between each respective pair of cuts in the first pair of lines and a respective nearest portion edge of the sheet defines a front section of a pocket, each area of sheet between each respective pair of cuts in the second pair of lines and a respective nearest portion edge of the sheet defines an upper bridge portion, a first region of each area of sheet between each pair of cuts in the first pair of lines adjacent and extending laterally from the respective connecting cuts defines a rear section of the pocket, and a second remaining region of each area of sheet between each pair of cuts in the first pair of lines defines a lower bridge portion.

Preferably a number of transverse fold lines, which may be score- lines or perforated or provided by any convenient means are provided at each end of each bridge portion to facilitate folding of the blank to form the pockets.

Each are defining a front portion may be provided with a cut defining a tab which may be folded to secure product when held in a pocket.

Each cut defining the tab may be any convenient shape such as a'c' shape and may be provided with an appropriate fold line.
