Description

DESCRIPTION

Box with inviolable closing system

TECHNIQUE SECTOR

The present invention refers to a box specially designed for the transport of objects by courier, which has a structure in which, once the box is closed, it cannot be opened again without evidence of said manipulation, due to its breakage. .

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, and more specifically in that of messaging, there are occasions in which boxes carrying objects with a certain value are improperly manipulated to partially or totally extract their content, so that with some skill in At the time of delivery of the box, its appearance may be that it has not been tampered with, with the consequent risk that this entails when debugging responsibilities.

Trying to avoid this problem, to date what is used are adhesive tapes as a personalized seal of the transport company in question which, although they allow evidence of external manipulation, said seals can be replaced by new seals by of the personnel of the transport company itself once the objects in question have been stolen, so its efficiency leaves much to be desired.

EXPLANATION OF THE INVENTION

The box with an inviolable closing system that is recommended solves in a fully satisfactory way the previously exposed problem, based on a highly effective solution.

For this, the box of the invention is constituted from the development of a sheet of die-cut cardboard, in which four rectangular or square sectors determining the larger and smaller side walls of the box are defined, whose ends are fixed through a lateral tab, side walls from whose lower edge emerge respective tabs determining the classic self bottom -buildable, with the particularity that two separate rectangular sectors emerge from the upper edge of both larger side walls, with a width according to the width of the wall from which they emerge, and slightly longer than half the length of the side walls smaller, sectors that are linked to each other through sectors that emerge from the smaller side walls and that are equally attached to said rectangular sectors, presenting a slightly shorter length and a rectangular notch in correspondence with the middle zone of its free edge, whose vertices emerge fold lines that extend to the upper vertices of the smaller side walls, defining a folding isoscelic trapezoidal central sector, which in closing the box defines a barrier that prevents manual access under the two main rectangular sectors.

More specifically, the greater length than half the depth of the box of one of the rectangular sectors defines a tab that in the closure of the box is intended to be inserted between the other sector and the folds as a bellows that it defines. the isoscelic trapezoidal central sector that emerges from the lesser lateral walls.

Said rectangular sector will include an elongated slot in its middle zone whose function will be explained later.

For its part, from the middle zone of the free edge of the other rectangular sector emerges a rectangular and foldable appendix that has a width in accordance with the width of the groove described in the other rectangular sector, being intended to be inserted into it, but with the particularity that said appendage includes foldable lateral expansions that make the assembly present a greater length than the slot, so that said expansions must be folded 180° at the moment of inserting the rectangular appendage in the corresponding slot, remaining coplanar with said appendage, presenting the slot with a thickness according to double the thickness of the cardboard sheet in which the box is obtained, so that once this appendage is inserted, the expansions tend to unfold thus blocking the exit through the slot of rectangular appendage and therefore preventing the opening of the box.

In this sense, it has been foreseen that in correspondence with the sides of said rectangular appendix, the rectangular sector that integrates said appendix includes cutting and/or weakening lines transversal to the slot, which will make the rectangular sector that defines the closure of the box is torn in this area before the lateral expansions can be extracted by deformation or breakage through said slot.

In any of the cases, the opening of the box will be clearly evidenced and visible even if an attempt is made to close it again, thus avoiding undue manipulation.

Based on this structure, the box is capable of incorporating a sticker as a seal on the only visible joint on its upper base that certifies the inviolability of the box.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, and especially figure 1, it can be seen how the box of the invention is made from the development of a sheet of die-cut cardboard, in which four rectangular sectors determining the side walls are defined. larger (1) and the smaller side walls (2), so that the free lateral edge of one of the smaller side walls (2) is fixed to the corresponding larger side wall (1) by means of an emerging tab (3). of the free lateral edge of the latter.

A series of tabs (4, 4', 4'' and 4''') emerge from the bottom of both the larger and smaller side walls that determine a conventional self-assembling bottom, whose structure is clearly visible in figure 2.

Well then, in accordance with the essence of the invention, it has been provided that a first rectangular sector (6) emerges from one of the larger side walls (1), while a second rectangular sector emerges from the larger and opposite side wall. (5), both with a width corresponding to the width of the wall from which they emerge, and with a length slightly greater than half the length of the smaller lateral walls.

These rectangular sectors are laterally linked to each other by means of folding sectors (7) that emerge from the smaller side walls (2) and which are equally attached to said rectangular sectors (5-6), being linked to one of them through a lateral tab (3'), elements that are slightly shorter in length than the contiguous sectors to which they are attached, including a rectangular notch (8) in correspondence with the middle zone of its free edge, from whose vertices fold lines emerge (9) that extend to the upper vertices of the smaller side walls, defining an isoscelic trapezoidal central sector and two trapezoidal sectors sides that when closing the box fold over the isoscelic trapezoidal central sector and under the main rectangular sectors (5-6) defining a barrier that prevents manual access under the two main rectangular sectors, including an additional element for closing and barrier functions access side, materialized in a trapezoidal tab (10) emerging from the edge of one of the lateral trapezoidal sectors defined on the sides of the rectangular cutout (8), and which is intended to fit over the free edge (10') of the sector opposite side trapezoidal and under the first rectangular sector (6).

In figure 4 it can be seen how the free end of the first rectangular sector (6) defines a closure tab (11) intended to be inserted under the second rectangular sector (5) and between the folds as a bellows that define the folding sectors ( 7) that emerge from the smaller lateral walls (2).

As for the first rectangular sector (6), and in accordance with figures 1 and 5, it will include an elongated slot (12) in its middle area, essential for locking the closure system.

In said elongated slot (12) a rectangular appendage (13) is intended to be inserted during the closing operations of the box, which emerges from the free edge of the second rectangular sector (5), an appendage that, although it presents a width according to the length of the Said slot laterally incorporates some folding lateral expansions (14) that make the assembly present a greater length than the slot, so that said expansions must be folded 180° inwards at the time of closing the box, as shown Figure 5, being coplanar with the rectangular appendix (13), for which the elongated slot (12) will present a width according to twice the width of the cardboard sheet in which the box is obtained.

In this way, and as shown in figure 6, once the assembly formed by the rectangular appendage (13) and the folding lateral expansions (14) is inserted into the elongated slot (12), the latter will tend to unfold, the which is not even necessary for it to be complete so that both rectangular sectors (5-6) remain locked together, preventing the opening of the box without breaking it.

In addition, it has been provided that in correspondence with the sides of the rectangular appendage (13) some cutting lines (15) will be established that extend into the respective transversal weakening lines (15'), which will make that when pulling the second sector rectangular (5) it tears/breaks along these lines of weakness, before the collapsible lateral expansions (14) can be extracted by deformation or break thereof.

Finally, it only remains to point out that, once the box is closed, a sticker may be placed as a seal on the intermediate and longitudinal zone of the upper base of the box, certifying its inviolability.
