Description

DESCRIPTION

Cardboard container with safety closure

TECHNICAL SECTOR

The present invention refers to a cardboard container with a security closure, which, although it was initially intended for the commercialization of detergent capsules, could be equally applicable in other fields in which similar features are required.

The object of the invention is to provide a container that has stable and safe closing means that prevent accidental opening of the container, and that require an unintuitive maneuver that prevents children from accessing its content.

BACKGROUND OF THE INVENTION

In the preferred field of application of the invention, that of detergent capsules, these are supplied in plastic containers fundamentally due to the fact that this type of product 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 is an obvious ecological problem, so its marketing in cardboard packaging would be the solution to this environmental problem.

However, there are no known reusable cardboard containers that include closing and opening means such that they prevent children from accessing their content.

EXPLANATION OF THE INVENTION

The cardboard container that is recommended comes to fill the technical gap described above, based on a highly effective solution.

To do this, the container of the invention is constituted from the development of a cardboard sheet in which a rectangular sector determining the bottom is defined, from whose larger sides two rectangular sectors determining the larger side walls of the container emerge, and which they are linked to each other through tabs that emerge from their minor lateral edges and that are fixed to each other by gluing.

Well, in accordance with the essence of the invention, one of the larger side walls extends into a closing lid and while the opposite one, in correspondence with the edge that defines the mouth of the box, includes a pair of tabs that are they fold externally, remaining flush with said larger side wall, determining blocking means as will be explained later.

More specifically, the lid extends in correspondence with its three free edges in sectors of low height that in the assembly of the box determine a perimeter skirt for said lid, with the particularity that said skirt at least in correspondence with its sector central and opposite the hinge line of the lid, it has a structure with at least a double wall, so that the internal wall, which can be single or double, has formal and dimensionally coincident notches with the tabs that are arranged on the inner wall. upper edge of the front larger lateral wall of the box, so that when closing the box, these tabs fit into said notches, preventing the opening of the lid.

To allow this manoeuvre, it has been planned that the outer wall of said double wall of the intermediate or central section of the lid skirt includes some holes that will also be facing said tabs, so that in order to open the box it is necessary to introduce simultaneously one finger through each hole to push the tabs and pull the skirt so that said tabs disengage from the notches in which they had been coupled, thus leaving the lid unlocked, a maneuver that is by no means intuitive for a child, offering for both a highly secure locking means.

For a higher level of security, it has been planned that this double-walled structure with recess and access hole to the recess for access to the corresponding The lock can also be reproduced on the sides of the skirt and the smaller side walls, respectively, so that to open the lid it is necessary to use four fingers, both thumbs and forefingers, simultaneously to open the lid.

As for the aforementioned double or triple wall structure of the skirt in its different sections, this can be obtained in different ways, since it can be obtained from sectors that extend above the skirt sector itself to fold on itself, or from sectors that extend laterally from the determining sectors of the side skirts and that are folded and superimposed on said central sector, solutions that obey mere design criteria and therefore do not affect the essence of the invention.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the container of the invention is constituted from the development of a cardboard sheet in which a rectangular sector determining the bottom (1) is defined, from whose larger sides two rectangular sectors emerge determinants of the larger side walls (2-3) of the container, and that are linked to each other through tabs (4-5) that emerge from their smaller side edges and that are fixed together by gluing, obtaining a rectangular prismatic body open at the top, equipped with a hinged lid (6), which is an extension of one of the larger side walls.

In any of the foreseen embodiment variants, the lid (6) includes, in correspondence with its three free edges, a perimeter skirt constituted by lateral (7) and intermediate (8) sectors that emerge from respective three edges of the lid (6).

For its part, from the upper edge of the larger side wall (2) emerge a pair of tabs (9) that fold externally, remaining flush with said larger side wall, slightly tending to unfold, which improves, as will be seen later. , the tendency to lock the lid.

Returning again to the perimeter skirt of the lid (6), as was said before, this can be obtained in various ways, without affecting the intended blocking system.

In this sense, the skirt, at least in correspondence with its central sector and opposite to the hinge line of the lid (6), has a structure with at least a double wall, so that recesses (10) are defined on the inner wall. formally and dimensionally coincident with the tabs (9), so that when closing the box, these tabs fit into said notches, blocking the lid, while holes (11) are made on the outer wall of the skirt, which will also remain facing said tabs, so that in order to open the box it is necessary to simultaneously insert a finger through each hole to push the tabs and pull the skirt so that said tabs detach themselves from the notches in which they had been coupled, thus remaining the lid unlocked, a maneuver that is by no means intuitive for a child, thus offering highly secure means of locking.

In the embodiment variant of figure 1, the central section of the skirt has a triple wall structure, where the notches (10) are located in two sectors that emerge from the sides of the lateral sectors (7) and that fold each other forming a double wall, and which, in turn, when assembled, overlap internally the intermediate sector (8) that defines the external wall of the skirt.

However, this configuration is merely exemplary, since as can be seen in the embodiment variant of figure 11, a simpler solution but Consequently, slightly less secure is that the housing defined by the notches (10) is simple, that is to say that there is only one notch (10) for each tab (9), a solution in which the lid would also be blocked.

In both cases, to release the cover (6), it is necessary to press simultaneously with two fingers on the tabs (9) after inserting them through the holes (11).

According to the embodiment variant of figures 13 and 20, the security level in the lid locking and opening system can be increased by extrapolating the same system to the lateral flaps of the lid and to the respective smaller lateral walls.

More specifically, in the embodiment variant of Figure 13, it has been provided that the tabs (4) that help to form the smaller side walls include, in correspondence with their upper edge in the assembly, a tab (9) analogous to those provided on the larger lateral wall (2).

For its part, the intermediate sector (8) of the skirt extends into a sector of the same size as this one but equipped with the two notches (10), a sector that folds over the previous one, and that extends laterally into two other sectors that they also include two notches (10).

Finally, each lateral sector (7) that determines the lateral sector of the skirt will include a hole (11) analogous to the previously described holes (11), so that they face the notches (10) provided on the internal face of the skirt. skirt and the tabs (9) provided in correspondence with the upper edge of the smaller side walls.

In this way, to open the lid it is necessary to use four fingers simultaneously, both thumbs and forefingers that will be inserted through the holes (10) in the central sector and lateral sectors of the lid skirt, pressing on the corresponding tabs (9).

This objective is also achieved with the embodiment variant envisaged in figure 20, where the only thing that changes is that the sectors that include the notches (10) instead of emerging from an extension sector of the intermediate sector (8) do so from emerging sectors of the lateral sectors (7) which in turn extend laterally in sectors provided with notches (10) and which internally overlap the intermediate sector (8).

In any of the cases, an economical and safe cardboard container is obtained, ideal for the aforementioned applications.
