The fruit or vegetable box is made from a one-piece die-cut from solid cardboard. Fig. 2 formed into a stackable upright in the four corners glued.

The one-piece die cut forms a base ( 1 ), two longitudinal walls ( 2 ), two end walls ( 3 ) and several adhesive tabs ( 4 , 5 ) for the four-corner gluing.

Each end wall ( 3 ) produces two folded, hollow corner supports ( 6 ) which are glued to the inside of the end wall ( 3 ) and one folded onto the two corner supports ( 6 ) and with adhesive flaps ( 4 ) between each corner support ( 6 ) and adhesive flap ( 5 ) the longitudinal wall ( 2 ) fixed deck and stacking strips ( 7 ).

Each corner support ( 6 ) is designed as a triangular column and extends over the entire height of the box and on the upper end of the two corner supports ( 6 ) of an end wall ( 3 ) the cover and stacking strips ( 7 ), which are continuous in the transverse direction of the box, lie loosely on.

Each corner support ( 6 ), which is triangular in cross section, stands with its hypotenuse ( 8 ) diagonally between the end wall ( 3 ) and the longitudinal wall ( 2 ) and in the upper region of its hypotenuse ( 8 ) a circular hole ( 9 ) is punched out, into which a hole on the deck - And stacking strips ( 7 ) articulated grip strips ( 10 ) with an end flap ( 11 ) for locking the triangular shape unfolded corner support ( 6 ) and the erected box (crate) engages releasably.

The hole ( 9 ) in the hypotenuse ( 8 ) is excluded outside its width bisector towards the front wall ( 3 ) and at a distance below the cover and stacking strip ( 7 ) resting on the corner supports ( 6 ).

The grip strip ( 10 ) which surrounds the hole ( 9 ) with its end fixing tab ( 11 ) lies at an angle to the floor ( 1 ) and the end wall ( 3 ) and forms with the cover and stacking strip ( 7 ) and the upper region of the end wall ( 3 ) a grip part ( 12 ) with a triangular cross section, which is gripped on the grip strip ( 10 ) by a grip tab ( 14 ) which is shaped out of the end wall ( 3 ) and in the end wall ( 3 ) releases a grip opening ( 13 ).

The two longitudinal ends of each end wall ( 3 ) are each extended to a folding flap ( 6 a) which can be folded over by four fold lines ( 15-18 ) to form the corner support ( 6 ). A slot ( 5 a) is punched out between the folding flap ( 6 a) and the adjacent adhesive flap ( 5 ).

The grip strip ( 10 ) is in a foldable connection with the cover and stacking strip ( 7 ) via a fold line ( 22 ) running in the longitudinal direction and is also due to the diagonal fold line ( 21 ) opposite the one between the adhesive flap ( 4 ) and the cover and stack strip ( 7 ) lying end flap part ( 7 a) foldable.

On each grip strip ( 10 ) a fixing flap ( 11 ), formed by a partially circular, preferably semicircular extension, is integrally formed on both length ends, which is set back relative to the adhesive flap ( 4 ) and lies within the expansion area of the flap part ( 7 a), namely on the free longitudinal edge of the grip strip ( 10 ).

At the two length ends of each cover and stacking strip ( 7 ) the adhesive flap ( 4 ) is connected and between the adhesive flap ( 4 ) and the cover and stacking strip ( 7 ) there is a fold line ( 19 ) and in the cover and stacking strip ( 7 ) and A diagonal fold line ( 20 , 21 ) - both lines ( 20 , 21 ) run in a V-shape to each other - in the grip strip ( 10 ) following the adhesive flap ( 4 ) - for the flat folding of each corner support ( 6 ), whereby the corner supports - Folding the grip strips ( 10 ) out of the lock ( 11 , 9 ) must be released.

The two longitudinal walls (2) each have a trapezoidal cutout (23) on whose parallel to the floor (1) extending, shorter trapezoidal longitudinal edge an inside glued-on by a fold line (24) inwardly folded over and on the longitudinal wall (2) stiffening strips (25) joins.

Further show the two longitudinal walls (2), the two via a respective fold line (26) for folding of the longitudinal walls (2) connected to the ground (1) with the longitudinal walls (2), on the outside of the corner post (6) and the adhesive flap ( 4 ) glued adhesive tabs ( 5 ).

The handle strip ( 10 ) formed on the outer longitudinal edge of each cover and stacking strip ( 7 ) and connected via the fold line ( 22 ) to the cover and stacking strip ( 7 ) corresponds in length to the distance between the two assigned corner supports ( 6 ) and his two fixing tabs ( 11 ) are also in this length.

In each of the two end walls ( 3 ), the handle opening ( 13 ) is provided with a handle tab ( 14 ) with an elongated, basic shape that can be bent out.

The grip strip ( 10 ) forms with the cover and stacking strip ( 7 ) and the grip tab ( 14 ) the hollow, triangular cross-section grip part ( 12 ) ( Fig. 1, 3-5), the grip strip ( 10 ) obliquely extends below and to the front wall ( 3 ) and the grip tab ( 14 ) runs obliquely upwards and towards the receiving space of the box and lies on the outside of the grip strip ( 10 ).

In the cover and stacking strip ( 7 ) from its fold line ( 27 ) to the end wall ( 3 ) two webs ( 29 ) are punched out as stacking stops, which extend vertically upwards to the cover and stacking strip ( 7 ) and in punched-outs ( 30 ) intervening to fix a stacked box; these punchings ( 30 ) are provided on both sides of the fold line ( 28 ) in the bottom ( 1 ) and the end wall ( 3 ).

The four-corner gluing takes place as follows: The folding flaps ( 6 a) are folded in by their three fold lines ( 16 , 17 , 18 ), so that first a square (rectangular) corner support ( 6 ) is created and the free flap part of the cathete ( 6 b) abuts the inside of the end wall ( 3 ) and is glued there to the end wall ( 3 ).

Then each cover and stacking strip ( 7 ) is unfolded on its two corner supports ( 6 ) around the fold line ( 27 ), lies loosely on the corner supports ( 6 ) and its two adhesive tabs ( 4 ) are down on the outside and that the second catheter-forming flap part ( 6 c) of the corner supports ( 6 ) folded down and attached to it by gluing.

Then the side walls ( 2 ) are folded up about their fold lines ( 28 ) so that their four adhesive tabs ( 5 ) lie against the cathets ( 6 c) of the corner supports ( 6 ) and the adhesive tabs ( 4 ) and then over the entire tab height Glue with the corner supports ( 6 ) and the adhesive tabs ( 4 ).

The two stiffening strips ( 25 ) have previously been folded inwards and glued to the side walls ( 2 ).

The erection ladder, which is formed from a one-piece blank, can be folded flat by folding the longitudinal walls ( 2 ) inwards onto the floor ( 1 ) and folding the corner supports ( 6 ) diagonally using the four-corner adhesive and attaching them to the end walls ( 3 ) are also folded towards the bottom ( 1 ) and then rest on the longitudinal walls ( 2 ); the end walls ( 3 ) fold against the bottom ( 1 ) around the fold line ( 28 ) and the fold line ( 17 ) in the hypotenuse ( 8 ) forms a diagonal edge for the flat folded corner support ( 6 ).

The longitudinal walls ( 2 ) buckle in the fold lines ( 26 ) and their adhesive flaps ( 5 ) lie on the longitudinal walls ( 2 ) with the end wall ( 3 ). The cover and stacking strips ( 7 ) fold outwards through the fold lines ( 27 ) and lie in one plane with the end walls ( 3 ). The handle strips ( 10 ) are also unfolded by their fold lines ( 22 ) and run in one plane with the cover and stacking strips ( 7 ).

In this flat folded position, the boxes can be stored and made available to save space.  

To erect the walls ( 2 , 3 ) in the use position of the box, the end walls ( 3 ) are grasped and pivoted upwards outward around the fold lines ( 28 ) between the end walls ( 3 ) and the floor ( 1 ), the longitudinal walls ( 2 ) also swivel up around their fold lines ( 28 ) with respect to the floor ( 1 ) and the corner supports ( 6 ), which were previously lying diagonally flat, are unfolded into their pillar shape, the cover and stacking strips ( 7 ) automatically extending onto the upper end faces of the corner supports ( 6 ) unfold. The columnar shape of the corner supports ( 6 ) is not yet completely triangular, but rather square due to the fold line ( 17 ), in which the hypotenuse ( 8 ) is bent towards the crate area.

After the front and longitudinal walls ( 3 , 2 ) have been erected, the two grip tabs ( 10 ) are bent downwards and in the direction of the end wall ( 3 ) about their fold line ( 22 ) so that they are at an acute angle to the end wall ( 3 ) and stand for cover and stacking strips.

When folding the handle strip (10) whose length ends press (securing flaps 11 and oblique edges 11 a) against the hypotenuse (8) and bend it in its fold line (17) to the flat in itself hypotenuse (8) and the triangular column shape is reached. At the same time, the fixing tabs ( 11 ) snap into the holes ( 9 ) and the inclined edge ( 11 a) is supported on the hypotenuse ( 8 ), so that the corner support ( 6 ) is supported by the two pressure points ( 11 , 11 a) locked in their triangular column shape and the entire box is fixed in its upright use position.

For a good folding over of the corner supports ( 6 ) and the grip strip ( 10 ), the fold lines ( 16 , 17 , 18 and 22 ) are partially formed by incision lines along their length. The fruit or vegetable crate preferably has a rectangular basic and spatial shape.
