Description

SPECIFICATION A quick-fold box The present invention relates to a quick-fold box and to a blank adapted to be used as a quick-fold box. The invention is particularly, although not exclusively, applicable to quick-fold boxes used for carrying lettuce.
In the packaging of lettuce, strong boxes are required which are able to be stacked upon each other without collapsing and spoiling the lettuce.
Previously, the boxes have either been supplied in the form of flat cardboard blanks, in which case the packer must undertake the time consuming operation of assembling the boxes or the boxes are supplied already assembled, in which case each box occupies a large volume making transportation expensive.
According to one aspect of the present invention, a quick-fold box includes a base and opposed side and end walls, the box being able to occupy an erect position in which the side and end walls extend upwardly from the base and a collapsed position in which the base, side and end walls occupy a generally flat configuration, the box being movable between the collapsed and erect positions by lifting the side and end walls, each end wall including at least two layers over substantially its whole extent. The box is able to be supplied to a packer in the collapsed position, in which position the boxes in the flat configuration can be tied in compact bundles.When the packer wishes to use the boxes it is only necessary for the side and end walls to be lifted to move the box to the erect position, and a strong box is provided by each end wall including at least two layers over substantially its whole extent.
Each side wall may be integral with a flap which extends from either end thereof, each flap being arranged to extend along an end wall to a central region thereof. Thus the flaps from each side wall may provide an additional layer to each end wall to further increase the strength and stability of the box in the erect position.
Each end wall may be folded about a line extending generally parallel to the junction of the end wall with the base, the fold defining the upper edge of the end wall in the erect position, and the fold providing the two layers. By folding over the upper edge of the end wall, a strong edge to that wall may be provided. The two layers may extend from the fold to the base to provide further stability for the box in the erect position. The flap of the side walls may extend between the two layers provided by the fold in the end walls, and thus each end wall includes at least three layers over substantially its whole extent, and an extremely stable box is provided as each flap is trapped between the two layers of the end wall.
Each end wall may include an opening extending therethrough in order to provide a handle for the box. The opening may extend through two layers of each end wall, the two layers around the opening adding strength to the box to prevent or resist the box from buckling or bending too much when lifted by the openings.
The side and end walls may be held in place relative to each other by stitches.
Alternatively the side and end walls may be held in place relative to each other. The direct engagement of one part of the box with another allows the boxes to be quickly assembled, without the need for a stitching, or other fastening operation, to be employed. Where the end wall is folded to provide two layers, and each layer extends from the fold to the base, the edge of the layer which is not integral with the base, in the region of the base, may extend into an opening in the base to provide a convenient way of engaging one part of the box with another. When the fold in the end walls is trapped between the two layers provided by the fold, it may only be necessary to provide the engagement of the end wall with the base in order to assemble the box.
According to another aspect of the present invention a quick-fold box includes a base and opposed side and end walls, the box being able to occupy an erect position in which the side and end walls extend upwardly from the base, and a collapsed position in which the base, side and end walls occupy a generally flat configuration, the box being moveable between the collapsed and erect positions by lifting the side and end walls, the side and end walls being held in place relative to each other by direct engagement af one part of the box with another.
According to another aspect of the present invention, a quick-fold box includes a base and opposed side and end walls, the box being able to occupy an erect position in which the side and end walls extend an erect position in which the side and end walls extend upwardly from the base, and a collapsed position in which the base, side and end walls occupy a generally flat configuration, the box being movable between the collapsed and erect positions by lifting the side and end walls, the upper edge, in the erect position, of each end wall being defined by a fold.
The present invention also includes a flat blank adapted to be formed into a quick-fold box according to the present invention.
The invention may be carried into practice in various ways, but one embodiment thereof will now be described by way of example and with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a quick-fold box in the erect position.
Figure 2 is a perspective view of the box shown in Figure 1 in the collapsed position, and Figure 3 is a plan view of a cardboard blank from which the box shown in Figures 1 and 2 is assembled.
As s shown in the drawings the box includes a base 10, a pair of opposed end walls 12 and a pair of opposed side walls 14.
In the erect position shown in Figure 1, each end wall 12 is comprised by a flap 16 which is folded about two parallel adjacent lines 18 and 20. The lines 18 and 20 define a panel 22 which lies in a horizontal plane along the upper edge of the end of the box. The flap 16 includes an outer layer 24 integral with the base 10 and extending upwardly therefrom, and an inner layer 26 extending downwardly from the line 20, the lowermost edge 28 of the layer 26 lying adjacent to the base 10. Extending between the layers 24 and 26 are a pair of inserts 20 integral with each of the side walls 14. The inserts 30 abut each other at their edges 32 (see Figure 3) and the inserts fill the space between the panel 22 and the base 10. A handle 34 is defined through the end wall 12 by a number of aligned openings 36 formed in the layers 24 and 26 and each of the inserts 30.As shown in Figure 3, each insert 30 includes a strip 38 which is able to be folded inwards to lie against the insert 30, when viewed in Figure 1, to provide a double thickness layer on the upper edge thereof.
A pair of stitches or staples 40 are inserted through the layers of the flap 16 and the inserts 30 in order to hold the side and end walls together, In one alternative the stitches may be dispensed with, as shown in Figure 3 in broken lines, by providing a tab 42 on the edge 28 of the inner layer 26 which can engage with an opening 44 formed along the edge region of the base 10.
As shown in Figure 1, each side wall 14 includes a vertical wall 46, and an inwardly directed horizontally extending panel 48, connected to the vertical wall 46 by a fold 50. The vertical wall 46 is connected to the insert 30 by a fold 52, and the panel 48 is connected to the strip 38 by two triangular shaped segments 54 (shown in Figure 3) which lie against each other in Figures 1 and 2.
In the erect position shown in Figure 1, the box is extremely strong and resists forces which tend to bend or buckle the box. The end walls are particularly strong having four layers of cardboard where the two layers of the flap 16 and the insert 30 and strip 38 overlap. The upper edge of the end walls is also extremely rigid as a result of it being formed from the fold in the flap 16 and the fold between the insert 30 and the strip 38.
In order to move the box from the erect position to the collapsed position, the panel 48 of the side wall is lifted slightly and the panel 48 and the wall 46 are then pushed inwardly to move around a fold 56 extending diagonally from each bottom corner of the box along and up each side wall. The end walls can then be pushed inwardly to lie on top of the end portions of the side walls. The collapsed boxes can then be tied into bundles for compact storage and transportation.
In order to move the box from the collapsed position, it may only be necessary to move the end walls upwardly and outwardly.
The blank shown in Figure 3 is stamped out of a sheet of corrugated cardboard comprising two planar sheets spaced from each other by a corrugated layer. The creases are either formed simultaneously with the blank, 0-' formed later as "Delta" creases.
