Abstract

Stackable cardboard box, obtained from the development of a rectangular sheet with lines of cut and fold to form a bottom, side, some head and two semitapas of upper closing of the box, characterized because the front ends are extended by one of its edges in extensions that have to be superimposed on the bottom to reinforce it, while the other edge of such ends extends into other extensions sectioned by an intermediate transversal line, determining two parts in each end, each of whose parts is endowed with three fold lines that in the subsequent folding through said fold lines are formed triangular prismatic columns that fold inward to be positioned in correspondence with each corner of the box, establishing a reinforcement thereof in its stacking, while the sectors that form the sides extend into extensions that form half-steps to close the box.

Description

STACKABLE CARTON BOX

n..E..SCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a stackable cardboard box, and

Specifically, a box obtained from the development of a single sheet with I folding and cutting Incas to form a rectangular prismatic box reinforced by vertical colunms in correspondence with the corners, and also reinforced the bottom with extensions that overlap the sector that The fund itself.

15 BACKGROUND OF THE INVENTION

Numerous types of cardboard boxes are known, but they are obtained by means of several picz: as, with the consequent complexity in the manufacture, the annado and the necessary machinery for it.

However, one-piece boxes are also known but they lack sufficient strength to carry heavy objects, much less boxes that can also be stacked without

25 warp when they are full.

DESCRIPTION OF THE INVENTION

The box that is "economized" has been designed to solve the problem described above, based on characteristics that are

they will be exhibiting throughout the present description, with an embodiment

simple, easy to manufacture and anchored, and the box in question is equipped

of a great resistance in the stacking with other full of products,

Although these are heavy.

5

More specifically the box of the invention is constituted from

of a rectangular cardboard sheet with two longitudinal fold lines

and three transversal fold lines, defining two sectors that are going to

form the major latins, alternated with two other sectors that are going to

10

Fonnar the testeros, and laterally two longitudinal sectors that are going to

form the bottom and two other sectors to form closing half-steps

from the box.

One of the sectors corresponding to the testeros,

l S

specifically the one that is free, has a small fixing flap

on the corresponding side when the assembly of the box is carried out.

On the other hand, in correspondence with the testeros, one of the

their edges extend over the extensions that have to overlap the

twenty

fund to reinforce this, while the other edge of the heads presents

an extension sectioned in co: correspondence with its transverse midline,

and each part with two fold lines that fold together in the box

and they will form, in each case, triangular prismatic columns in

correspondence with the corners, presenting the free edge of one of the

2S

sides of those triangular prismatic corners a small extension

of interlocking in a groove established for this purpose in the background, so

achieve the anchoring and immobilization of the columns, without the need for

adhesives or additional elements.

30

Each part that has to confonate a prismatic column, after the

confonnación of this one folds towards the interior to form the own vertical column in each corner, that is to say that they are not independent elements but that they form part of the same box and they are obtained in the annado and later folded of the same, to be located in Own

5 corners without detriment of decrease of used cardboard area in the constitution of the box itself.

The box thus constituted pennite its stacking with other products loaded, even if they are heavy products,

10 since the bottom is resistant by virtue of the extensions that reinforce it, and also resistant to stacking by the triangular prismatic columns of the corners that are located interionnently.

In addition and as and, to the above, the fixation

15 of the columns do not require elements or adhesives to keep them stable in their positioning, since by virtue of the small extension that they present in the upper edge and their fit in the bottom or base, it establishes the immobilization in the annate of each column.

20 DESCRIPTION OF THE DIEIUJOS

To complement the description that is being made and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof,

25 accompanies as an integral part of said description, a set of drawings where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1.-Mm: stra a view corresponding to the flat development 30 of the cardboard sheet from which the box object of the invention is obtained.

Figure 2.-Mwe: stra a perspective view of the sheet represented in the previous figure but in a folded position, from which the annate of the box itself is obtained.

Figure 3. - Shows a perspective view of the box with the confonation dee: a single prismatic column of one of the corners, without being folded inwards and the other three columns without confonating.

Figure 4.- Shows a perspective view of the box represented in the previous figure, including the four prismatic columns armed but not positioned inside the box.

Figure 5. - Finally, it shows a perspective view of the fully annulled box, with the columns in their position of use, and the closing caps of the box in the open position.

PREFERRED REALIZATION OF THE FNVENTION

As can be seen in the aforementioned figures, the stackable cardboard box object of the invention is obtained from the development of a cardboard sheet with cut and fold lines that will form two rectangular sectors (4) that in it. The fund will contain the bottom, two sectors (2) that in the annate will fit the heads, one of which has an external flap (3) for fixing by gluing in the perimeter of the box. It also includes two sectors (1) of the same length as the sectors (4) of the fund, and whose sectors (1) will form the sides of the box, so that in opposition to the sectors (4) of the fund, another two are included sectors

(5) that will form half-lanes for closing the box.

In the conformation of the box in question, the folding of the aforementioned sectors entails that a bottom formed by the sectors (4), longitudinal sides (1) and some pockets (2) be formed, with the special feature that said front ends (2) extend along one of its sides (6) that will be superimposed on the bottom formed by the sectors (4), to reinforce said bottom, while in opposition to those extensions (6), two extensions are planned with a transverse intermediate cutting line (7), connecting two parts in each of these extensions, parts that have, in each case, fold lines (8) to form triangular prismatic columns that are arranged on the inside of the corresponding corners to the box.

The triangular prismatic columns shaped and referenced in general with the number (9), as shown in Figure 4, for example, are formed first on the upper edge of the testers (2) and then, through a fold line (12), they fold inwards, as shown in Figures 4 and S, to be perfectly positioned in the corners, logically inside the box, with the special feature that before the folding inwards triangular prismatic columns (9), an extension (10) of the upper edge is provided to fit into a groove (11) of the bottom or base of the box itself.

Claims (2)

1.-Stackable cardboard box, obtained from the development of a rectangular sheet with cut and fold lines to form a bottom, some sides, some heads and two semi-layers of upper closure of the box, characterized in that the heads are extended by one of its edges in extensions that have to be superimposed on the bottom to reinforce it, while the other edge of such testers extends in other extensions sectioned by an intermediate transverse line, determining two parts in each tester, each of whose parts is endowed of three fold lines that in successive folding through said fold lines are confined triangular prismatic columns that fold inwards to be positioned in corrcspondcnc: ia with each corner of the box, establishing a reinforcement of this in its stacking , while the sectors that form the sides extend into extensions that form half-lanes paths for closing the box. 2.-Stackable cardboard box, according to claim 1, characterized in that the triangular prismatic columns have a small extension at the bottom edge of the same, which is embedded in a groove established in the bottom or base of the box, to maintain the stable and armed position of each column in its final situation.
