Abstract

A packaging tray comprises a panel of stiff but foldable board material, having two substantially parallel fold lines on either side of a base 1 and side walls 2 on outer sides of the fold lines. Each fold line is defined by a plurality of cuts 4, each cut having a part running substantially parallel to the fold line and at least two parts running at angles greater than 45 degrees, e.g. greater than 65 degrees to the fold line, and of a length less than twice the thickness of the panel. The tray is used in a method of packaging an array of products positioned on the base 1. The side walls 2 are folded to abut sides of the products, the fold lines retaining each side wall at approximately 90 degrees to the base once it is folded into that position. A sheet of film is wrapped around the tray and the array of products, the wrapping may be shrink wrapping.

Description

PACKAGING TRAY
[0001] This invention relates to a packaging tray.
[0002] A known paperboard packaging tray is used to store and convey an array of products such as cans or drink cartons. The tray comprises a rectangular base carrying the products, and four side walls. At each corner there is a small flap which is an extension of one of the side walls and is joined to the adjacent side wall using hot melt adhesive. The tray is formed on a tray erecting machine at high speed (80-100 trays per minute). The machine collates the products into appropriate arrays and places them on the base of the tray. The machine then folds the side walls and end flaps into place around the array, temporarily holding them until the adhesive is effective. Next, the tray enters a shrink-wrap tunnel and a polymeric film is shrunk around the tray and the products.
[0003] When such a tray of products arrives in a store, the film is removed so that the products can be purchased one by one. However, products of lesser height may not be properly visible over the front side wall of the tray. This is true even if the products are on lower shelves, as the major identifying information is usually disposed on a vertical side of the product.
[0004] Surprisingly, it has been found that a practical tray can be formed which does not have four glued side walls and is therefore significantly more efficient.
[0005] The present invention provides a packaging tray comprising a panel of stiff but foldable board material, the panel having two substantially parallel fold lines defining a base therebetween and side walls on outer sides of the fold lines, each fold line being defined by a plurality of cuts, each cut having a part running substantially parallel to the fold line and at least two parts running at angles greater than 45 degrees, e.g. greater than 65 degrees thereto and of a length less than twice the thickness of the panel.
[0006] The length of said substantially perpendicular parts may be essentially equal to the thickness of the panel.
[0007] In an embodiment of the invention, at least one of said parallel parts of the cuts is provided on one side of the fold line and at least one other of said parallel parts of the cuts is provided on the other side of the fold line. In particular the parallel parts of the cuts may lie on alternate sides of the fold line in sequence.
[0008] The inventive fold lines retain each side wall at approximately 90 degrees to the base once it is folded into that position. Thus the machine does not need to hold the side walls in place nor is any adhesive required.
[0009] If the base has a side which lacks a side wall, the problem of poor product visibility can be solved by placing the tray on a shelf with that side at the front.
In an embodiment of the tray, said side walls on the outer sides of the two fold lines are the only side walls.
[0010] The invention also provides a method of packaging an array of products, comprising the steps of: providing a tray as defined above, positioning an array of products on the base of the tray, folding the side walls through an angle of approximately 90 degrees to abut sides of the products, and wrapping a sheet of film around the tray and the array of products. The wrapping may in particular comprise shrink wrapping.
[0011] The present invention will now be described in more detail, by way of example only, with reference to the accompanying drawing, the single figure of which is a plan of a tray according to the invention.
[0012] The drawing shows a rectangular tray cut from double faced corrugated board material, optionally coated with a tacky material on an upper side. Two generally parallel fold lines are parallel to and near (e.g. 5 to 50 mm from) opposite sides, in this case the longer sides, of the tray. The fold lines define a base 1 in the centre of the tray and side panels 2 outside the fold lines.
[0013] In the drawings, dotted lines represent a crease that has been formed in the paperboard and solid lines represent a cut. Central axes of the fold lines are formed by aligned creases 3. These are interrupted by U-shaped cuts 4 having a longest leg at the base of the U, parallel to and spaced from the central axis by a small distance, e.g. 0.5 to 3 mm. The arms of the U are formed by short cuts running substantially transverse to the fold line but in this example diverge in the direction away from the base of the U, by an angle of 10 to 60 degrees from each other, thus each lies at an angle of 60 to 85 degrees to the fold line. In this example the orientation of the U shaped cuts alternates so that a cut with its base on the outside of the fold line is followed by one with its base on the inside. The short cuts may be e.g. 0.5 to 10 mm long -their length may be related to the thickness of the tray so that the offset between the long legs of successive cuts is substantially equal to the thickness of the panel.
[0014] An array of products placed on the base 1 substantially fills it. The side walls 2 are then folded upwards, preferably by a machine, through 90 degrees around the products. Remarkably due to the shape of the cuts 4 the side walls 2 stay in this folded position without being held by the machine. The tray with its products can then be shrink wrapped and shipped as normal.
[0015] It will be appreciated that the invention saves a considerable amount of board material compared to the known tray.
[0016] In a store, the tray is placed on a shelf with one of the sides not having a side wall at the front so that even products of low height are visible.
