Foldable does and piano for that.

The invention relates to a foldable box with a bottom and two pairs of upright walls arranged opposite each other, which are foldably connected to the bottom and which are attached to each other at the head ends by means of overlapping upright wall parts, wherein the one pair of walls is provided with foldable widening strips and foldable extension flaps, at least part of the extension flaps being secured to a corresponding part of the other pair of walls, while in a pair of walls from the bottom 10 vertices one below the other angle of approximately 45 ° upwardly extending oblique fold line is provided.

A similar folding box is described in the non-prepublished Dutch patent application 81.05838.

In this previously manufactured box, the one pair of opposing walls and the associated wall parts, which overlap the other two upright walls, are provided with foldable strip-shaped extensions, which can be folded at folding corners, at the corners of the box. are spaced apart by a cutout and vertical fold lines are provided from the ends and from the center of these cutouts such that a recessed corner is formed in each of the corners of the box with the respective corner wall parts of the box, while in the other pair of upright walls, an oblique fold line extending at an angle of about 45 ° from each of the base corners of the box is provided. In addition, the strip-like extensions of the one pair of opposed, upright walls foldable about the fold lines are overlapping fastening on that pair of opposed walls and the associated wall parts, except at the location of the recessed corners. A reinforcing member comprising an 8204276 - 2 - ϊ * compressible support leg is provided in the recessed corners. These support legs serve to support the weight of stacked, stacked boxes. Because the support leg is compressible, the leg can remain in the box when folded. A drawback of this previously manufactured box is that the supporting legs must be manufactured separately, kept in stock and fitted, which requires additional personnel and makes the box more expensive. Moreover, with frequent use by different persons, it is not guaranteed that the support legs will remain in the recessed corners, especially not when the boxes are used for packaging vegetables, fruit and the like, the boxes being at auctions, markets and in shops. exposed to rough treatment.

The object of the invention is to eliminate the drawbacks of the previously manufactured box.

This object is achieved in that according to the invention the foldable widening strips are folded in a position parallel to the bottom, because the oblique folding lines in the one pair of walls in the widening strips have been extended and because in the widening strips from the end points of the folding line a second oblique fold line parallel to the first oblique fold line is provided between the widening strip and the wall.

Because the foldable widening strips are folded in a position parallel to the bottom, a top wall is partly formed in the top surface of the box, which consists of supporting edges or stacking edges at two opposite ends of the box and these supporting edges or stacking edges support the weight for stacked, stacked boxes.

Moreover, thanks to the widening strips, the one pair of upright walls to which they are arranged remains upright in the erected position of the box and furthermore these upright walls remain straight, so that the other pair of upright walls also remain upright. This makes filling the box easier. Because the oblique fold lines in the one pair of walls in the widening strips have been extended and in the widening strips from 8204276 "" "!, Ρ ^ ιρ ™ · τν '-,. :: 1 & i 3 the end points of the fold line between the widening strip and the trend each time a second scalloped folding line is arranged parallel to the first-mentioned scented folding line, the box according to the invention can, despite the presence of the supporting edges 5 in the top of the box, simply fold up the pair of upright walls of the box are moved from the folded position to the unfolded position in one operation.

In a preferred embodiment of the foldable dobs according to the invention, the other pair of walls 10 are provided with foldable extension flaps, which are fixed with part of their surface on a corresponding part of the one pair of walls, and those extension flaps are provided with foldable second widening strips which are folded in a position parallel to the bottom and come to lie under the first-mentioned widening strips.

By applying these measures, said one pair of walls is reinforced by mounting the extension flaps of the other pair of walls thereon, and moreover, the carrying or stacking edges in the top surface of the box are at least locally doubled and thereby reinforced.

In a particularly efficient embodiment of the folding box according to the invention, the other pair of opposing walls are provided near both ends with foldable third widening strips, which are likewise folded in a position parallel to the bottom and which lie below the first-mentioned widening strips. .

This extends the carrying or stacking edge along the other pair of walls of the box, further increasing the carrying capacity of the box.

The invention also relates to a piano for a foldable does, provided with a bottom panel and with two pairs of opposite wall panels, which are foldably connected to the bottom panel, wherein one pair of wall panels is provided with extension strips, which are provided by folding lines 35 are connected to the wall panels and of extension flaps, which are connected by 8204276 * 9 4 folding lines to the extension strips and wherein in a few wall panels from the two corners of the bottom panel one is at an angle of approximately 45 ° with respect to the folding line an oblique fold line extending between the wall panel and the bottom panel is arranged.

Such a piano is described in the non-prepublished Dutch patent application 81.05838.

The piano according to the invention differs from this previously manufactured piano in that the wall panels, first widening strips and extension flaps thereof are cut T-shaped from one pair of walls, in that the said oblique folding lines are arranged in that pair of wall panels and in the widening strips. are extended and in that in the widening strips of the one pair of wall panels, from the end points of the folding line between the widening strip and the wall panel, a second oblique folding line parallel to the first mentioned oblique folding line is provided.

In a preferred embodiment of the piano according to the invention, the other pair of wall panels are provided with 20 extension flaps, which are connected by folding lines to the end edges of those wall panels, and those extension flaps are provided on the outer side with second widening strips, which are provided by folding lines are connected to those extension flaps.

The extension flaps 42, 43 and 44, 45 are provided on the outside with second widening strips 50, 51 and 52, 53 respectively, which are connected to the widening strips by folding lines 54, 55 and 56, 57 respectively. Semicircular cuts 58, 59 and 60, 61 respectively are made in the folding lines 54, 55 and 56, 57 respectively, the function of which will be explained in more detail hereinafter.

1 The side wall panels 2 and 3 are further provided near their end edges on the outside with third widening strips 62, 63 and 64, 65, which are connected to the side wall panels 2 and 3 by folding lines 66, 67 and 68, 69.

The side wall panels 2 and 3 are finally provided in the middle with folding strips 70 and 71 respectively, which are connected to the side wall panels 2 and 3 by 15 folding lines 72 and 73 respectively. Cut out slots 72 "and 72" connect to the folding lines 72 and 73 "and 73" and 73 ", respectively. The function of the folding strips will be explained in more detail later.

Assembling the folded box, see fig. 3, 20 the piano according to fig. 1 takes place in the following manner;

The end wall 6, 10 is folded inwardly around the fold line 8 on the bottom 1 and at the same time the hatched parts 6 'and 6 "together with the parts 10', 14 and 10", 15 and the extension flaps 14 and 15, respectively, are folding lines 26 and 27, respectively, folded outwards by + 180 ° back on the end wall 6.

The folding strips 70 and 71 are then provided with glue around the folding lines 72 and 73 inwardly folded and glued to the side wall panels 2 and 3.

The extension flaps 42 and 44 are then folded around the folding lines 46 and 48 on the hatched parts 2 and 3.

At the end wall 7, 11, the same procedure as described above for the end wall 6, 10 is followed.

Subsequently, the hatched parts 6 ', 6 "35 and 7', 7" are provided with adhesive and the two side wall panels 8204276 ..... ......: ^ ........... ............. '*' 'ir Τ;' ...... ^ '! ψ ^' "·· '.......

2 and 3 around the fold lines 4 and 5 inwardly folded, with the shaded parts 42 *, 44 'glued on both sides (fig. 1) to the' glued shaded parts 6 ', 6 ”and the hatched parts 43 ', 45' on parts 7r, 7 ".

5 Finally, the flaps Ί4, 15 and 16, 17 are glued on the top (fig. 1), folded around the folding lines 30, 31 and 32, 33 and on the bottom (fig. 1) of the shaded parts 2 ", 3" and 2 ", 3" glued.

Then the folded door according to the invention, which has been partially drawn in Fig. 3, is ready and these boxes can be stored in large numbers in a relatively small space, for instance in the storage space of the box manufacturer.

The box according to the invention is folded in the above manner by the manufacturer and delivered to the user in a folded state. The user can easily unfold or "set up" the box, namely by pulling the end walls 6 and 7 upwards with the tape and, if necessary, folding the widening strips 10 and 11 on the end walls 6 and 7, see figure 3.

When stacking the foldable boxes on top of each other, the lips of an underlying box, cut through cuts 38-41 and 58-61, protruded into the recesses 34-37 of an overlying box, so that the boxes do not lie relative to can shift each other. By folding the folding strips 70 and 73, ventilation openings are formed in the side wall panels 2 and 3 when the boxes are stacked on top of each other. These vents may be necessary, for example, when the stacked boxes are filled with moisture-releasing products, such as fruits and vegetables.

30. The folding boxes according to the invention can be adapted to the load requirements in a particular application of the boxes by using different types of cardboard, which are dependent on the weight of the filled boxes, the stacking height, the mode of transport, etc.

The box according to the invention is preferably 8204276-8 made of solid cardboard, which can be used in various thicknesses. It goes without saying that other materials, such as plastic, can also be used.

If one wants to reinforce the supporting or stacking edge even further, for instance when one wants to use a box for relatively light products for relatively heavy products, one can use at least a part 10 ', 10 "and 11 on the first widening strips 10, 11. Attach "and 11" to the inwardly facing side thereof cardboard or wooden reinforcement plates 10b JO, for example sticking.

The box according to the invention can furthermore be strengthened significantly in terms of carrying capacity by locally mounting a reinforcement plate of cardboard, plastic or other relatively stiff material on the hatched parts 2 '- 2 ", J5 3' - 3" and / or on the end wall panels 6 and 7 within the folding lines 26, 27 and 28, 29.

A strip of plastic or other relatively stiff material can be glued to the widening strips 10, 11 and the extension flaps 14, 15 and 16, 17 to further strengthen and increase the carrying capacity, which strip at the location of the folding strip 18, 30, 26, 27, 31, 39, respectively, the folding lines 20, 32, 28, 29, 33, 21 in the widening strips 10 and 1.1 are provided with so-called "plastic dabs", where on the spot the material is thinner and is thereby made foldable and which strip at the location of the cardboard lips formed by the cuts 38-41 is provided with molded-on lips which have the same function as the cardboard lips.

The box can furthermore be of single and double-walled design and although a rectangular embodiment has been described and shown in the drawing, a square shape could also be used, in which the boxes can moreover be manufactured in various sizes.

Although in the described and drawn embodiment the stacking or carrying edge is formed on the short sides of the box, this carrying edge can just as well be formed on the long sides 82 (14 276 9).

Furthermore, in order to reduce Bet differentiating from each other, it is sufficient to have an upright lip on the end walls and the recess in the Bottom and the end wall, which are then arranged in Bet center. The box can also be put in

Curves are slightly tapered, ie the Bottom has a smaller-r surface than the Top, in which case the recesses can be omitted.
