Description

The invention relates to a fruit or vegetable box made from a one-piece die-cut blank made of solid cardboard, which has a bottom, two longitudinal walls, two end walls and adhesive tabs for four-corner gluing.

Fruit or vegetable boxes made of cardboard have become known in various designs and are formed from a die cut that contains the individual wall parts.

The wall parts are erected to form the box and connected to one another by plug-in tabs, which allows space-saving, flat storage of the die cuts, but results in cumbersome handling when putting the individual boxes together in their position of use.

Glued fruit or vegetable boxes have also become known, but they already have their box shape after being glued and thus take up a large volume for storage and provision.

The object of the invention is to improve a fruit or vegetable crate from a one-piece die cut from solid cardboard in such a way that it is finished by four-corner gluing, can be folded flat, stored at the place of use in a few easy steps to the crate and locked in a stable shape by simple means in the box shape and designed as a stackable box with high stability.

This object is achieved according to the invention by the characterizing features of patent claim 1, the design features listed in the subclaims representing advantageous developments of the task solution.

The object of the invention extends not only to the features of the individual claims, but also to their combination.

Through the invention, a ready-glued in the four corners, erectable fruit or vegetable box made of solid cardboard has been created, which in the folded state lies flat, space-saving to store and transport and for use at the place of use, e.g. B. on the fruit or vegetable field, can be erected to the box in a few easy steps.

During this erection process, the box is automatically stiffened by the hollow corner supports, which are integrally formed and glued in one corner, also unfold and interact with the floor of the box using anchoring means, as a result of which the standing walls are firmly fixed.

Furthermore, in the unfolded state, the cover and stacking strips, which are integrally formed and glued on the corner, are loosely supported, by means of which further stiffening takes place and which simultaneously form stacking surfaces for boxes to be stacked one above the other.

This box is simple in die cutting, inexpensive and safe in four-corner gluing, very easy to use and extremely stable, and can be used for a wide variety of agricultural foods.

• 5 shows a section in the transverse direction of the box of a corner area with corner support,
• Fig. 6 is a plan view of the one-piece die cut of the fruit or vegetable box.

The fruit or vegetable crate is formed from a one-piece die-cut blank made of solid cardboard according to FIG. 6 to form a stackable standing tray which is glued in the four corners.

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) forms 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 longitudinal wall (2) fixed cover and stacking strips (7).

Each corner support (6) is designed as a square 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.

For the positionally stable fixing of each corner support (6) in the erected position, it engages with a fixing wedge (8) in a hole (9) in the floor (1), this fixing wedge (8) at the corner of the box-receiving space of each corner Corner support (6) extends.

The two longitudinal ends of each end wall (3) are each extended to a folding flap (6a) which can be folded over by four fold lines (10) to the corner support (6) and which shows the punched fixing wedge (8) towards the longitudinal wall (2).

At the two length ends of each cover and stacking strip (7) there is the adhesive flap (4) and between the adhesive flap (4) and the cover and stacking strip (7) there is a fold line (11) and in the cover and stacking strip (7) in Connection to the adhesive flap (4) is provided with a diagonal fold line (12) for the flat folding of each corner support (6).

The two longitudinal walls (2) each have a trapezoidal cutout (13), on the short trapezoidal longitudinal edge running parallel to the floor (1), a stiffening strip (15) folded inwards by a fold line (14) and glued to the longitudinal wall (2) on the inside joins.

Furthermore, the two longitudinal walls (2) show two each with a fold line (16) for folding the longitudinal walls (2) onto the floor (1) with the longitudinal walls (2), externally to the corner support (6) and to the adhesive tab (4 ) glued adhesive tabs (5).

Handle openings (17) are provided in the two end walls (3) by means of wall parts (17a) that can be pushed out.

The four corners are glued as follows:

The folding flaps (6a) are folded inwards so that the square corner support (6) is created and the free support tab (6b) lies against the inside of the end wall (3) and is glued there to the end wall (3).

Then each cover and stacking strip (7) is folded onto its two corner supports (6) around the fold line (21), lies loosely on the corner supports (6) and its two adhesive flaps (4) are pushed down to the outside of the corner supports ( 6) folded down and attached to it by gluing.

Then the side walls (2) are folded up so that their four adhesive tabs (5) rest on the outer sides of the corner supports (6) and the adhesive tabs (4) and then the entire height of the tabs is glued to the corner supports (6) and the adhesive tabs (4).

The two stiffening strips (15) 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 using the end walls ( 3) are also folded towards the bottom (1) and then rest on the longitudinal walls (2). The longitudinal walls (2) bend in the fold lines (16) 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 (12) and lie in one plane with the end walls (3).

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 outwards around the fold lines (18) between the end walls (3) and the floor (1), the longitudinal walls ( 2) also swivel up around their fold lines (19) with respect to the floor (1) and the corner supports (6), which were previously lying diagonally flat, are unfolded into their square column shape, the cover and stacking strips (7) automatically extending onto the upper end faces of the corner supports ( 6) unfold.

After the uprighting of the longitudinal and end walls (2, 3) is carried out, the corner supports (6) snap with their fixing wedges (8) into the holes (9) of the floor (1) and this is the upright use position of the fruit or Vegetable crate stabilized and secured.

So that the fixing wedges (8) have sufficient freedom and are not damaged when the box is folded, a slot (20) is cut out for each fixing wedge (8) in the region of the fold line (18), into which the corner support (6) with its fixing wedge ( 8) penetrates.

The fruit or vegetable crate preferably has a rectangular basic and spatial shape.
