Description

CARTON BOX FOR FRUIT, VEGETABLES AND SIMILAR

OBJECT OF THE INVENTION

The present invention relates to a cardboard box for fruits, vegetables and the like, of the type of self-assembling from a flat development.

The object of the invention is to be able to reduce the internal capacity of the box according to the needs required at all times, maintaining its external dimensions.

BACKGROUND OF THE INVENTION

There are numerous types of cardboard boxes used for the storage and transport of fruits, vegetables and other similar products, boxes that are obtained from the development of a sheet with fold and cut lines to form the corresponding bottom or base in its assembly of the box, the major sides and the heads.

There is a type of box based on the aforementioned concept but that its testers are extended in triangular flaps that will form upper bridges in correspondence with each tester and logically projected horizontally inwards while these triangular flaps of the testers are They project respective extensions with fold lines to form three sectors that in the assembly are folded inwards, reinforcing the front, and even the lateral ones, in combination with an extension of each one of the lateral sides.

Well, this type of box for its specific application in certain products, such as lettuce, supposes that it is necessary to use two-size boxes, depending on the size of the lettuce, all this in order that these lettuces are perfectly adjusted inside the box.

Specifically, in a standardized way for the transport of lettuces there are cardboard boxes of 600 x 400 mm. and 580 x 385 mm. Naturally, the existence of two boxes of different sizes means a greater cost, both for the manufacturer of the boxes and for the storage and stowage that is required when having to store or stack two types of boxes.

DESCRIPTION OF THE INVENTION

The box that is recommended, based on the one referred to in the previous section, presents some novelty characteristics that make it possible to reduce the size of the box when the user considers it appropriate.

More specifically, the box of the invention is of the type that is obtained from the development of a cardboard sheet with a rectangular central sector that will constitute the bottom, two extreme and smaller extensions that will constitute the heads, and two longitudinal or greater extensions that will constitute the lateral ones, after the folding of said extensions perpendicular to the bottom sector.

The box also and as it is also conventional, has the particularity that the extension formed by the testers is prolonged in two triangular flaps whose ends or sides extend an extension with an intermediate fold line to form two extensions that in the assembly of the box will form extensions that are attached to the inner side of the end parts of the sides, reinforcing them, while said sides have an extension that in the assembly of the box are attached to the extreme and internal parts of the pointers.

Well, from these characteristics, the box of the invention has the particularity that each of the extensions corresponding to the pockets, that is to say those derived from the triangular flaps, are extended in turn in an extreme sector with small tongue at its outer edge, so that in the assembly said extensions or sectors can be attached to the inner side of the sides, anchoring in grooves established for that purpose in the bottom, corresponding to the maximum capacity of the box, or being able to occupy those novel sectors a diagonal position in correspondence with the corners, being interlocked through its small fin in oblique grooves provided in correspondence with the corners or areas near the corners of the bottom, achieving in this second case the closing of wide spaces of the own corners, which logically can not access the load and consequently reduce the effective capacity of the box, however maintaining its external dimensions.

Therefore, by means of a single box two capacities can be achieved, a maximum and a reduced one, so the storage or stocking of two different types of boxes will not be required, so that since the box is externally coincident, it is of capacity maximum or reduced capacity, it is possible to stack between them, with one or another capacity, and therefore it is reduced in the volume occupied both in the stock or storage and in transport.

DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

PREFERRED EMBODIMENT OF THE INVENTION

As can be seen in the aforementioned figures, the box of the invention is obtained from the development of a cardboard sheet, which can be single cardboard, corrugated cardboard, double wall, etc.

In any case, the cardboard sheet includes a central and rectangular sector (1) that will constitute the bottom, from which the lateral extensions (2) that will form the major laterals are derived longitudinally, while from the minor sides of that central and rectangular sector (1) of the bottom, the extensions (3) that are going to constitute the testeros are derived.

The extensions corresponding to the sides (2) have extreme extensions (4) that in the assembly of the box must be attached internally to the heads (3) reinforcing them.

For their part, said testers (3) have triangular extensions (6) that in the assembly of the box will form horizontal and upper bridges in correspondence with each testers, as shown in figures 4 and 5.

The triangular extensions (6) extend in turn laterally in extensions (7) with a fold line that gives rise to another extension (8), the latter having a small external fin (9).

In the assembly of the box, the small fins (5) are housed in grooves (5 ') established in the triangular extensions (6) of the heads, that is, those that form the upper bridges, while the fins (9) of

'. 11111il1 '

the extensions (8) are housed in the grooves (9 ') of the bottom itself (1) of the box, thus being perfectly armed, although without the possibility of varying its capacity.

Well, from these characteristics, the novelty of the invention is that the extensions (7) that are derived from the triangular extensions (6) of the heads (3), and after a fold line, are extended in sectors ends (10) with a small external fin (11), so that in the assembly of the box these sectors (10) can be attached to the inner side of the sides (2), maintaining the total internal capacity of the box , the sectors (10) being locked by housing their fin (11) in grooves (11 ') established for this purpose in the bottom (1) of the box.

On the other hand, these sectors (10) can occupy an oblique situation, housing their fin (11) in oblique grooves (11 ") of the bottom itself (1) of the box, so that when it occupies the sectors (10 ) This oblique position logically reduces the internal volume of the box, that is to say its capacity, as a result of which in the corners there are inaccessible spaces for the products contained in the box, being able to see the two solutions in Figures 4 and 5, in the first case with the sectors

(10) laterally attached to the heads (2), and in the second case arranged obliquely in correspondence with the corners.
