Description

THIS INVENTION relates to a blank from which a box can be erected, and to a box erected from such a blank.
According to the invention there is provided a blank from which a box can be erected, the blank comprising a rectangular base panel and, at each corner of the base panel:
a first side panel joined to the base panel along a first fold line defining the corresponding side of the base panel;
a fold-over side panel joined to the first side panel along a second fold line parallel to the first fold line;
a first end panel joined to the base panel along a third fold line defining the corresponding end of the base panel and having an end edge transverse to the third fold line;
a fold-over end panel joined to the first end panel along a fourth fold line parallel to the third fold line;
an end reinforcing flap joined to the first side panel along a fifth fold line transverse to the first fold line, the end reinforcing flap having a first free edge transverse to the fifth fold line and lying adjacent said end edge, a second free edge spaced from and parallel to the fifth fold line, and a third free edge spaced from and parallel to the first free edge;
a side reinforcing flap joined to the fold-over end panel along a sixth fold line transverse to the fourth fold line and having a fourth free edge

-3transverse to the sixth fold line and lying adjacent the second free edge, and a fifth free edge parallel to and spaced from the fourth free edge; and a corner reinforcing flap joined to the fold-over side panel along a seventh- fold line transverse to the second fold line and having a seventh free edge transverse to the seventh fold line and lying adjacent the third free edge, an eighth free edge spaced from and parallel to the seventh fold line and lying adjacent the fourth free edge, and a ninth free edge spaced from and parallel to the seventh free edge.
It will be understood that two adjacent corners will share the same first side panel and fold-over side panel, or first end panel and foldover end panel, as the case may be.
The fourth fold line may be constituted by a pair of closely spaced parallel fold lines whose spacing from one another is such that when the fold-over end panel is folded with respect to the first end panel through
90° about each of the fold lines of the pair, the spacing between the foldover end panel and the first end panel is substantially equal to the thickness of the material from which the blank is made.
The corner reinfoi'cing flap may have spaced, parallel eighth and ninth fold lines which are parallel to the seventh fold line, so that it can be folded to form a reinforcing corner structure that is triangular m horizontal section of the box when in the erected condition.

-4The fold-over side panel may be shorter in length than the first side panel, to accommodate the corner reinforcing structure. In other words, the distance between the seventh fold lines at opposite ends of the fold-over side panel may be shorter than that between the fifth fold lines at opposite ends of the first side panel.
The second fold line may be constituted by a pair of closely spaced parallel fold lines whose spacing from one another is such that when the fold-over side panel is folded with respect to the first side panel through 90° about each of the fold lines of the pair, the spacing between the fold10 over side panel and the first side panel is substantially equal to twice the thickness of the material from which the blank is made.
The blank may be of a corrugated material whose fluting runs in the direction from the first side panel on one side of the base panel to the first side panel on the opposite side of the base panel, whereby, in the 1 5 erected form of the box, the fluting of the corner reinforcing flaps extends in the vertical direction of the box.
The invention extends to a box when erected from a blank as outlined above.
The invention will now be described in more detail, by way of example, with reference to the accompanying drawings.

-6On each of the shorter sides of the base panel 12 there is a first end panel 22, this being joined to the base panel along a third fold line 24. Each panel 22 has an end edge 23 at each opposite end thereof, the end edges being transverse to the fold line 24. On that side of the panel 22 that is opposite the base panel 12 there is a fold-over end panel 26. This is joined to the panel 22 along a pair of closely spaced fourth fold lines 28 which are parallel to the fold line 24.
At the end of the panel 14 there is an end reinforcing flap 30, this being joined to the panel 14 along a fifth fold line 32 which is transverse to the fold line 16. The reinforcing flap 30 has a first free edge 34.1 which is transverse to the fold line 32 and lies alongside the corresponding end edge 23, a second free edge 34.2 which is spaced from and parallel to the fold line 32, and a third free edge 34.3 which is spaced from and parallel to the free edge 34.1.
At the end of the panel 26 there is a side reinforcing flap 36 which is joined to the panel 26 along a sixth fold line 38. The reinforcing flap 36 has a fourth free edge 40.1 which is transverse to the fold line 38 and lies alongside the free edge 34.2, a fifth free edge 40.2 which is spaced from and parallel to the free edge 40.1, and a sixth free edge 40.3 which is transverse to the free edges 40.1 and 40.2.

-742 whicn is joined to the panel 18 along a seventh fold line 44 which >s transverse to the fold lines 20, The corner reinforcing flap 42 has a seventh free edge 46.1 which is transverse to the fold line 44 and lies alongside the free edge 34.3, an eighth free edge 46.2 which is spaced from and parallel to the fold line 44, and a ninth free edge 46.3 which is spaced from and parallel to the tree edge 46.1. The free edges 34.2 and 46.2 an? aligned with one another and lie alongside the free edge 40.1.
The corner reinforcing flap 42 is provided with a pair of spaced fold lines 48 and 50, these being parallel to the fold line 44, The fold lines 48 and 50 divide the flap 42 into three flap portions 42.1, 42.2.
and 42.3.
it will be seen that the pane! 18 is shorter in length than the panel 14 (i.e. the distance between the fold lines 44 is shorter than that between the fold lines 32).
The panel 18 is provided with a series of three iocKing tabs along that edge thereof which is opposite the fold lines 20, m tne base panel 12, adjacent the fold line 18, there is a corresponding nuncer of cutout openings 54 for receiving the locking tabs 52. Likewise, the pane! 26 is provided, along that edge thereof which is opposite the fold lines 28, with a pair of locking tabs 56. In the base panel 12, adjacent the fold line 24, there is a pair of corresponding cut-out openings 58 for receiving the

-8locking tabs 56.
The manner in which a box is erected from the blank 10 will now be described. First, the flaps 30 are folded upwardly through 90° along the fold lines 32 and the panels 14 and 22 folded upwardly through
90° along the fold lines 16 and 24 respectively, so that the flaps 30 lie on the inside faces of the panel 22. Next, the flaps 36 are folded downwardly through 90° (as viewed in Figure 1), along the fold lines 38, and the panels 26 then folded inwardly through 180° about the fold lines 28 (i.e. through 90° about each of the two fold lines 28). The flaps 30 will now be located between the panels 22 and 26, and the flaps 36 will lie on the inside faces of the panels 14. To this end, the spacing between the fold lines 28 is such that the spacing between the panels 22 and 26 is substantially equal to the thickness of the corrugated cardboard material from which the blank is made.
Next, in respect of each of the flaps 42, the portion 42.1 is folded downwardly (as viewed in Figure 1) so that it forms an angle B (see
Figure 3) with respect to the panel 18, the flap portion 42,2 is folded about the fold line 48 so that it lies in a plane parallel to the panels 22 and 26, and the flap portion 42.3 is folded inwardly through 90° about the fold line
50. When this has been done the free end of the flap portion 42.3 will lie along the inner (or upper, as seen in Figure 1) face of the panel 18. The panel 18 is then folded through 180° about'the fold lines 20 (i.e. through
AP/T 0 0/01908
APO Ο 132 4
-9£0° about each of the two fold lines 20). The flap 36 and the flap portion
42.3 will then oe located between the panels 14 and 18. To tms end, the spacing between the fold lines 20 is such that the spacing between the panels 14 and 18 is substantially equal to twice the thickness o« tne corrugated cardboard material from which the blank is made. The gap that there is between the end of the pane! 18 and the end of the panel 14 as a result of the difference in their lengths accommodates the resulting corner structure.
When the panels 26 and 18 are folded through 180c as 10 aforesaid, the locking tabs 56 engage with the cut-out openings 58 and the locking tabs 52 with the cut-out openings 54, to retain the box n the erected condition.
The box will now be in the condition illustrated m Figure 3.
It will be seen that, when the box is in the erected condition, 1b the fluting of the panels 22 and 26 will run horizontally, whereas the fluting of the flaps 30 (which are located between the panels 22 and 26' run vertically. The fluting of the panels 22 and 26 will offer maximum strength to the ends of the box against bulging, whereas the fluting of the reinforcing flaps 30 will provide maximum strength to the ends or the box against vertical loading. Furthermore, the fluting of the panels 14 and 18 will run vertically, to provide the sides of the box with maximum strength
0 6 10/00 4/dV
APO013 2 4
-10against vertical loading, whereas the fluting of the reinforcing flaps 36 extend horizontally, providing the sides of the box with maximum strength against bulging.
The fluting of the corner reinforcing flaps 42 will run 5 vertically, providing the corners of the box with maximum strength against vertical loading.
It will be seen that, because of the particular configuration of the blank, there is no restriction on the length of the reinforcing flaps 36, so that they can, if desired, be half as long as the panels 14. They will then provide strength against bulging over essentially the full length of the sides of the box. Furthermore, if the height of the end panels 22 is equal to or greater than half their length, the reinforcing flaps 30 can be long enough to provide maximum vertical strength over essentially the full length of the ends of the box.
5 The reference numerals that appear in brackets in the appended claims have been included to make it easier to identify the features of the claimed invention in the specific construction illustrated by way of example in the drawings. This should not be interpreted as limiting the scope of the claims to the specific construction illustrated.
