Description

SPECIFICATION Cardboard boxes This invention relates to boxes made of cardboard including corrugated cardboard and is especially concerned with a tray-like box such as is used for containing vegetable produce e.g.
iettuces. Such boxes as commonly used have collapsible long sides so that they can be packed but this has the disadvantage that they tend to collapse when stacked.
The object of the present invention is to produce a box blank which can be supplied to customers in flat form or partially made up but still collapsible but will be rigid in finally made up condition.
According to the invention a box blank consists of a base, long side walls separated from the base by crease lines, end walls separated from the base by crease lines, top margins separated from the long side walls by crease lines, end flaps separated from the ends of the top margins by crease the lines and end flaps separated from the ends of the end walls or long walls by crease lines.
This blank can be supplied flat. The blank may be provided with diagonal crease lines in the end walls extending from the corners of the base towards each other to the outer edges of the end walls.The flaps on the end walls can then be glued to the upstanding side walls and the box can then still be collapsed in this partially made up state and the customer can erect the box and staple or glue the flaps on the side margins by a suitable machine to complete the erected box. Since the flaps on the side margins will be glued over the diagonal creases, the end walls are no longer collapsible and the box is very rigid.
A constructional form of the invention is illustrated in the accompanying drawings wherein: FIGURE 1 is a box blank made in accordance with the invention; FIGURE 2 shows the erected box of Figure 1; and FIGURE 3 shows a modified box blank.
The box blanks of Figures 1 and 2 has a base 10, and long side walls 11, 12 separated from the base by crease lines 13, 14. End walls 17, 18 are separated from the base 10 by crease lines 19, 20. Top margins 23, 24 are separated from the long side walls 11, 12 by crease lines 25, 26. End flaps 27, 28, 27A, 28A are separated from the ends of the top margins 23, 24 by crease lines 30.
End flaps 34, 35, 34A, 35A are separated from the ends of the walls 17, 1 8 by crease lines 36.
Diagonal crease lines 39, 40, 39A, 40A extend from the four corners of the base 10. In each end wall the diagonal crease lines extend towards each other at 450 out to the outer edge of the end wall.
In making up the box, the walls are erected and the flaps 34, 35, 34A, 35A are glued to the outer surfaces of the side walls. The margins 23, 24 are bent over and the flaps 27, 28 27A, 28A are glued on to the outside of the end walls.
If desired however the triangular piece B of each flap 34, 35, 34A, 35A may be glued to the outer surface of the triangular piece A of the walls 11, 12. The box can then still be folded flat and supplied to the customer for easy erection. Crease lines will be provided on the indicated diagonal broken lines.
In the modification shown in Figure 3, the flaps 34, 35, 34A, 35A are not attached to the end walls but are separated from the side walls by crease lines 42, 43, 42A, 43A and are referenced 34B, 35B, 34C, 35C. In this construction the blank may be supplied flat, the customer erects the walls and glues the flaps 34B, 35B, 34C, 35C on the outside of the end walls over the diagonal creases and then glues the flaps 27, 28, 27A, 28A or the outer surfaces of the flaps 34B, 35B, 34C, 35C. Alternatively, the walls may be erected and the flaps 34B, 34C, 35B, 35C glued to the walls 11, 12. In this condition the box may still be folded fiat and supplied to the customer who can erect the walls and glue the flaps 27, 28, 27A, 28A on the flaps 34B, 35B, 34C, 35C.
The base 10 will normally be much wider than shown. Sufficient gaps 45 will be left between the flaps to accommodate the thickness of the cardboard.
1. A box blank consisting of a base, long side walls separated from the base by crease lines, end walls separated from the base by crease lines, top margins separated from the long side walls by crease lines, end flaps separated from the ends of the top margins by crease lines and end flaps separated from the ends of the end walls or long side walls by crease lines.
2. A box blank as claimed in claim 1 having diagonal crease lines in the end walls extending from the corners of the base towards each other to the outer edges of the end walls.
3. A box blank as claimed in claim 1 or 2 wherein the end flaps are attached to the long walls and a triangular portion of each end flap is glued to a triangular portion of the adjacent end wall leaving the blank still in collapsible condition.
4. A box blank substantially as described with reference to Figures 1 and 2 or 3 of the accompanying drawings.
