Description

Horde open at the top for fruits or the like.

The invention relates to racks or trays for shipping, storage and sale of fruits or the like, z. B. of fruit, vegetables, potatoes etc.

Such trays consist of a flat container, usually with Corner reinforcement, individually or in stacks, if necessary with suitable straps for dispatch and on top of each other in storage rooms or at retail outlets individually can be put up for sale. These hordes or crates mostly exist to this day wooden.

It was also suggested that fruit trays made of waterproof cardboard material to produce, namely the flat blanks were assigned to trapezoidal ones Side walls wall parts that can be knocked inwards to define knock-in flaps and used for reinforcement on an inwardly foldable wall part a blocking floor that is also hinged to it. A lock of the compiled Obsthorde was made with protruding tongues in corresponding incisions of the Exterior floor. This design resulted in considerable weakening of the cardboard body, when used for heavy packaged goods, such as fruit, etc., had an adverse effect.

It has therefore also been suggested to use narrow intermediate fields in the case of fruit trays to articulate the inner wall parts in connection with foldable reinforcement corners, the inner walls then being secured by the adjacent inner walls. To make these hordes stackable one looked at two opposite Side walls increases in front. These known designs result in complicated ones Cut to size and were therefore expensive compared to wooden fruit crates. Furthermore The well-known cardboard fruit trays were also able to withstand the high demands of transport difficult to withstand. It has therefore already been suggested to use corrugated cardboard, however These constructions also lack the one required for the intended use at hand Strength of the assembled packaging body.

As experience has shown, a fruit tray must be made of cardboard material not only be tightly locked in itself, so that a bending of the side walls under the pressure of the filled fruit is impossible, but must go beyond that In addition, the filled trays of fruit when placed one on top of the other have a very significant impact Can take pressure. To meet these practical requirements in every respect suffice, the invention consists in the fact that the corrugations of the corrugated cardboard for the cut across the side walls equipped with articulated corner tabs known per se run through it and use a corrugated cardboard bottom with the corrugations of the outer bottom as a barrier bottom glued to the crossing waves on the outer floor or otherwise. this is attached. In a preferred embodiment, the directions of the waves can all Be supporting side walls, so that they are vertical when the tray is assembled run to the ground.

The waves of corrugated cardboard standing on two opposite sides enable a stability that does not bulge due to pressure loads, in connection with the vertical waves of the tuck-in flaps at the bordered ones Pages. Here is especially at the folded corners due to the vertical Course of the waves the compressive stress on the horde so largely intensified that According to practical experience, all of these requirements are sufficient.

Due to the further feature of the invention, namely the one glued on the inside Corrugated board base with corrugations perpendicular to the outer base of the corrugated board not only created a locking effect against the inserted side walls, so that these are held in their desired position, but the inner floor in connection with the outer floor creates a very strong and durable in the manner of plywood Base plate. In addition, due to the glued-in interior floor, in connection with the outer floor of the corrugated cardboard has reached that after the filled trays have been stacked an impression is created in the ground, which causes the tray to slip during transport is excluded. This results inter alia. also by the fact that the size of the base plate coincides with the upper inner recesses of the assembled tray.

The fruit trays according to the invention can be used for filling weights of 10 pounds can be used up to over 35 pounds and there are maximum loads of about 280 to 330 kg. Such a horde is filled with any means of transport Stacked condition, without risk of damage, the high transport stresses grown.

The drawing illustrates, for example, embodiments of the Subject of the invention, namely Fig. I a blank, Fig. 2 is a front view an assembled tray, Fig. 3 a cross section in the direction of the narrow side, Fig. 4 is a top view of the assembled pack, Fig. 5 is a blank of a Another embodiment, Fig. 6 is a longitudinal section of Fig. 5, Fig. 7 is a cross section the execution according to Fig. 5 and 6 in the direction of the long side, Fig. 8 a cross section the version according to Fig. 5 and 6 in the direction of the narrow side.

The material used to make the tray is made of corrugated cardboard Od. Like., which proves to be advantageous, the corrugated cardboard after the Wart, as well the bottom down or the entire blank, possibly also the output corrugated cardboard, appropriately water-repellent wet solid or otherwise in a suitable manner impregnate or prepare.

For the corrugated cardboard cutout, as shown in Fig. I, are on a bottom part 1 on the opposite longitudinal sides, the wall parts 2 and hinged to this via strips 12 further wall parts 3 with bottom tabs 4. The walls 2 are narrowed trapezoidally towards the outside and from the intermediate strip I2 from the wall parts 3 expanded trapezoidal to the outside accordingly.

Wall parts 5 are on the narrow sides. over intermediate fields I3 wall parts 7 and bottom tabs 8 articulated thereon. On the outer edges of the wall parts 5 tuck-in flaps 6 are articulated.

After the side walls 2 and 5 have been raised, the wall parts are 3 knocked in over the tuck-in flaps. whereupon the wall parts 7 strikes (see Fig. 3).

The bottom flaps 4 of the longitudinal walls 2, 3 are folded inwards. On the narrow sides, depending on the width dimensioning of the walls 5 and 7 either vertical outer walls 2, as Fig. 3 shows, or an inclined position each according to the cutting dimension. The walls 5 are in the form of tuck flaps 6 directed obliquely outward by parallelograms.

The bottom flaps 8 are expediently knocked outwards and can, as Fig. 2 shows, be so long that the wall parts 7 run straight down. The inner walls 3 and 5 of the finished shelf are locked through a base plate 9. In this base plate 9, the waves I run, as in FIG Fig. 4 dash-dotted lines drawn, in the direction of the narrow side, while at the bottom I of the blank the waves I I perpendicular to it in the direction the long side. It is of course also possible to watch the waves of the To let the weli cardboard blank (Fig. I) run in the direction of the narrow sides and perpendicular to this are the corrugations of the base plate 9.

It is possible within the scope of the invention, just if the narrow sides 5 and 7 according to the longitudinal sides 2, 3 trapezoidal shape, so that all four pages with an assembled tray according to such a blank as well conically narrow upwards.

In the embodiment according to Fig. 5 to 8 are on a bottom part 1a the longitudinal walls 2 ,, and on them via intermediate strips 12a the impact walls 3av and hinged to these bottom tabs 4a. The ones with blankets on both sides Waves 14 of this blank run in such a way that when the walls 2a, 3a the waves are directed perpendicular to the ground, d. H. are load-bearing.

In Fig. 5 these waves are indicated by the dash-dotted lines 14 and shown in Fig. 6 and 7 as waves in the outer floor Ta. On the sub-floor 1a are 15 wall parts 5a and above with attached or glued tabs Intermediate strips 13a articulated further wall parts 7a with bottom tabs 8a. the Waves I6 of these wall parts run, as indicated by dash-dotted lines in Fig. 5, perpendicular to shafts I4, i.e. H. when erecting these wall parts 5a, 7e are also supporting the waves I6. Between the tabs 15 is adjacent to this an inner bottom 9a glued in or otherwise attached, the shafts 17 of which are perpendicular run to the shafts 14 (Fig. I). The ceilings I8 protrude from this inner floor 9a the outermost corrugations I7a The side walls 2aJ 3a are, as described for Fig. I, trapezoidal and the tuck-in tabs 6a on the walls Sa form outwardly directed Parallelograms.

The blank according to Fig. 5 can be dimensioned so that the outer walls 2a and 3aJ like Ahh. 3 shows, straight or, under certain circumstances, according to Fig. 5 at an angle outside and the inner walls run slightly obliquely inwards, so that these are also like the walls 5a. 7a extend downwards like a roof (Figs. 7 and 8).

The tabs 4a are dimensioned so that they are after turning of the side walls over the extended ceilings I8 lay on the shafts 17a and a secure anchoring is guaranteed, while the tabs 8a after pushes in on the outside.

To ventilate the contents of the rack, continuous Holes 19 are incorporated, if necessary also on the broad sides.
