Description

DESCRIPTION

Cardboard container with safety closure for its lid

TECHNIQUE SECTOR

The present invention refers to a cardboard container, of the type made up of two pieces, a main body or box, and its corresponding closing lid which, although it has been initially intended for the marketing of detergent capsules, It could be equally applicable in other areas where similar benefits are required.

The object of the invention is to provide a container that has stable and safe closing means, which prevent accidental opening of the container, and that require a non-intuitive and coordinated maneuver and a minimum size of hands that prevents access to its contents. to kids.

BACKGROUND OF THE INVENTION

In the preferred scope of application of the invention, that of detergent capsules, these are supplied in plastic containers mainly due to the fact that this type of products can be very dangerous for children if they have access to them, so that this type of packaging includes opening means that require a certain skill that makes it unlikely that children will be able to open them.

However, the plastic nature of this type of packaging represents an obvious ecological problem, so marketing it in cardboard packaging would be the solution to this environmental problem.

Trying to avoid this problem, although cardboard containers with locking mechanisms for their lid are known, these are complex mechanisms that require an equally complex structuring for the box, which significantly increases their manufacturing and assembly costs.

EXPLANATION OF THE INVENTION

The cardboard packaging that is recommended completely satisfactorily solves the previously mentioned problem, based on a simple but effective solution.

To this end, the container of the invention is of the type made up of a main container body and a closing lid attachable to the mouth of the latter.

More specifically, the main body is constituted from the development of a die-cut cardboard sheet with folding lines, in which a rectangular sector determining the bottom of the container is defined, from whose larger sides emerge two rectangular sectors determining the rear and front larger side walls, while the smaller side walls of the container are obtained from the superimposition and fixing of respective emerging side sectors of said larger side walls, together with emerging inner side sectors of the smaller sides of the bottom, fixing these elements by gluing, determining in the assembly a rectangular prismatic body open at the top, from which two tabs emerge from the edges of the smaller side walls in the shape of an inverted “U”, which fold outwards on said smaller side walls to determine a lid locking mechanism as will be seen below.

For its part, from the larger rear side wall emerges a sector determining an internal folding lid, which increases the degree of security of the container, which ends at its free end in a tab that fits into a slot provided on the middle area. top of the anterior major side wall of the container.

As for the cover, it is constituted from the development of a die-cut cardboard sheet with folding lines, in which a central rectangular sector is defined that determines the upper base of the cover, from whose larger sides separate sectors emerge. rectangular sectors determining the larger lateral edges of the perimeter skirt of the lid, while from its smaller sides emerge two rectangular sectors of smaller width that when folded define the smaller lateral edges of the skirt of the lid, which will present a three-layer structure, to which these sectors extend superiorly into another sector that folds inwards, so that in the internal chamber that is defined between these two sectors, lateral expansions of the larger sides of the lid are intended to be inserted, which have a length half that of said space, to converge in its middle area, these elements being fixed by means of gluing points applied to the sector that will define the innermost wall, so that the intermediate and internal walls include formal and "U" cutouts. dimensionally coincident with the “U” tabs at the mouth of the box, which tend to be partially deployed, sufficient to lock into the chambers that define these notches and prevent the removal of the lid.

To carry out this extraction maneuver, it has been planned that the smaller and external side walls of the lid include windows through which the user's fingers can pass, and that give access to these deformable "U" tabs, so that It is necessary to activate both tabs simultaneously to unlock the lid and be able to pull it without initially releasing said tabs, all of which requires a hand size larger than that of a child, in addition to being an unintuitive maneuver. which is practically impossible to arrive at by chance.

In this way, a cardboard container is achieved with opening means that are not intuitive for a child, achieving a safe, simple and perfectly functional and structurally resistant container.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the container of the invention is constituted from a main body (1) and a lid (2), where the main body (1) is constituted from the development of a die-cut cardboard sheet with folding lines, in which a rectangular sector determining the bottom (3) of the container is defined, from whose larger sides emerge separate rectangular sectors determining the larger rear (4) and anterior (4') side walls. , while the smaller side walls of the container are obtained from the superimposition and fixation of separate lateral sectors (6-7) emerging from said larger side walls, together with interior side sectors (5) emerging from the bottom (3).

As can be seen in Figure 1, the different height of the lower lateral sectors (5) and the lateral sectors (6-7) allows that with a simple tail cord (8) along one of the latter sectors, these three elements are fixed together, as shown in figure 6, forming a rectangular prismatic body open at the top.

More specifically, two tabs (9) emerge from the edges of the lateral sectors (6) in the shape of an inverted "U", which fold outwards on said smaller side walls, tending to partially unfold them, which will determine the locking means for the lid (2).

In accordance with another of the characteristics of the invention, and to increase the degree of security of the container, it has been planned that the rear larger side wall (4) extends superiorly into a rectangular sector determining a folding internal lid (10). , which ends at its free end in a tab (11) that fits into a slot (12) provided on the upper middle area of the anterior major side wall (4') of the container.

This internal folding lid (10) will adopt a slightly inclined arrangement when it is attached to the larger anterior side wall (4'), due to its slightly longer length than the bottom of the container, which makes it difficult to open, including some arched cutouts ( 13) in correspondence with the edges of its free edge, acting as handles that facilitate the opening maneuver of said internal cover.

According to Figure 2, the lid (2) is constituted from the development of a die-cut cardboard sheet with folding lines, in which a central rectangular sector determining the upper base (14) of the lid is defined, from whose larger sides emerge two rectangular sectors determining the larger lateral edges (15) of the perimeter skirt of the lid, while from its smaller sides emerge two rectangular sectors of smaller width that, when folded, define the smaller and external lateral edges (16). ) of the lid skirt, these minor lateral edges presenting in their assembly a tri-layer structure, where the minor and external lateral edges (16) extend superiorly in a rectangular sector determining the minor and internal lateral edge (17) of the skirt of the lid, which is affected by a “U” notch (18) formally and dimensionally appropriate to the inverted “U” shaped flange (9) that emerges from each lateral sector (6) of the main body of the container , with the particularity that between these two external (16) and internal (17) smaller lateral edges, two “J”-shaped expansions (19) that emerge from the sides of the larger lateral edges (15) are intended to fit internally. , and which have a length half the length of said smaller lateral edges, in order to define an intermediate wall during assembly, in which the "J" profiles overlap symmetrically, defining a second "U" notch that overlaps the previously mentioned “U” notch, allowing a greater degree of insertion of the tab (9) in said chamber, improving the degree of locking of the lid.

These elements will be fixed using the gluing points (19') shown in figure 2.

Thus, and as shown in figures 13 and 14, the lid locking maneuver will be extremely quick and simple, since it will be enough to move the lid downwards until the tabs (9) fit the chamber defined by the “U” notches in the intermediate and internal walls of the smaller edges of the lid, and a “click” can be heard when said automatic locking occurs, which prevents the extraction of the lid by wedged into these elements.

Finally, in order to unlock the lid, it has been provided that on the smaller and external side edges (16) of the lid there are windows (20) for access to the tabs (9) by inserting the user's fingers.

Consequently, to unlock the lid it is necessary to insert at least one finger through each of the windows (20) and simultaneously press said tabs (9).

However, since it is a prominent element and is flush with the inner edge of the lid skirt, it is necessary to pull on the edges of said skirt to slightly and momentarily deform said skirt in order to release the tabs (9).

This means that the maneuver must be carried out with the thumbs, while with the rest of the fingers the free edge of the cover is pulled outwards, this edge having a sufficient separation from the window to require a size of hands. greater than those of a child.

In this way, an extremely safe container is obtained, practically impossible for a child to open, at least without resorting to some type of tool.
