Description

DESCRIPTION

Cardboard container with security closure for the commercialization of detergent capsules and the like

TECHNIQUE SECTOR

The present invention refers to a cardboard container that, although initially intended for the commercialization of detergent capsules, could be equally applicable in other areas in which similar features are required.

The object of the invention is to provide a container that, in addition to presenting stable and secure closing means, which prevent accidental opening of the container, and which require a non-intuitive maneuver that prevents children from accessing its contents, ensures that the container is not deformed when the lid is released.

BACKGROUND OF THE INVENTION

In the preferred field of application of the invention, that of detergent capsules, these are supplied in plastic containers mainly due to the fact that this type of product can be very dangerous for children if they have access to it, so that this type of packaging includes means of opening that require a certain amount of 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 marketing it in cardboard packaging would be the solution to this environmental problem.

Trying to obviate this problem, cardboard containers with a hinged lid are known that have a perimeter skirt based on double walls, on the internal wall of which are established some cutouts in which the respective tabs that emerge from the external face of the container are intended to fit. the mouth of the main body of the container, in such a way that they define locking and locking means for the lid, which are released through of holes made on said skirt, pressing the user's fingers simultaneously on said tabs.

The problem with these systems is that since they are containers intended to be opened and closed multiple times to gain access to their contents, when manually pressing on the aforementioned tabs, the walls from which said tabs emerge tend to deform, so that after several uses, the container may lose its physical integrity.

EXPLANATION OF THE INVENTION

The carton package that is recommended satisfactorily solves the problem previously exposed, based on a simple but effective solution.

For this, and more specifically, the container of the invention is constituted from the development of a die-cut cardboard sheet with folding lines that define a rectangular prismatic container with a foldable upper lid on the upper edge of its rear wall, lid that includes a perimeter skirt that affects its front edge and its side edges, so that, on one or more outer faces of the vertical walls of the container, at the level of its mouth, at least one tab is established, preferably more than one , to make it difficult for children to open the container, tabs that fold over said walls, constituting some prominent elements that will determine the blocking means for the box, presenting the aforementioned skirt of the lid in correspondence with these elements a multilayer structure in which a formally and dimensionally adequate cutout or cutout is internally defined for said flanges, so that they fit into said cutouts, so that said multilayer structure includes an external wall that covers said cutouts, these being externally hidden, with the exception of respective holes intended to allow passage for the respective fingers of the user in order to be able to press on the said tabs to cause the unlocking of the lid.

In this way, to unlock the cover it is necessary to press simultaneously on the aforementioned tabs, so that they disengage from the cutouts on which they were locked, so that once unlocked the cover can be tilted to to access the content inside.

Well then, in order to prevent the walls from which the aforementioned tabs emerge from being deformed during these lid release maneuvers due to the pressure exerted on them, it has been provided that the vertical front face of the container is finished off at the top in a sector hinged with dimensions in accordance with the plan dimensions of the container, such that it includes on its free edge a tab intended to fit into a slot established in correspondence with the hinge area of the lid.

In this way, this folding sector, in addition to defining a second lid or internal lid for the mouth of the container, constitutes a stiffening element for said mouth that prevents the vertical walls on which the locking tabs of the main lid are established from deform during the pressing maneuvers on them.

To open it, it will suffice to release the tab that emerges from its free end from the complementary groove in which it is intended to fit, while precisely by virtue of said structuring, the simple tilting towards the mouth of the container will cause the stabilization of this lid. interior, at the moment in which said tab engages in the groove established in the fold line of the main cover.

Given the structure of the container, the closure of the main lid by tilting it will cause an automatic locking of the main lid, when the tabs re-fit into the cutouts in the skirt of the box due to their own tendency to unfold them, all this through a fast, simple and automatic maneuver.

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, which allows its continued use without losing its physical integrity.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the container of the invention is constituted from the development of a cardboard sheet die-cut with folding lines, in which a rectangular sector determining the bottom (1) of the container is defined, from whose larger sides emerge two rectangular sectors determining the rear (2) and front (2') larger side walls, while the smaller side walls of the container are obtained from the overlapping and fixing of two side sectors (4-5 ) emerging from said larger side walls, together with some sectors lower sides (3) emerging from the bottom (1).

For its part, the larger rear side wall (2) is extended in a rectangular sector acting as a lid (6) which, as previously stated, will present a perimeter skirt that, when closing it, externally embraces the smaller side walls. and to the anterior wall (2').

This skirt is obtained from a rectangular sector that emerges from the front edge of said cover (6), determining the front (7) of the skirt, and two rectangular sectors that determine the side skirts (8) of the cover, all of them extending in determining sectors of a double wall (9-12) that folds internally over the skirt, giving it greater strength, and being linked to each other by means of intermediate tabs (13).

The double walls (12-9) that fold on the inside of the front (13) and sides (8) of the skirt, include some "U" cutouts (10), formally and dimensionally adequate to receive some tabs (17). that emerge from the mouth of the container, folding over the smaller side walls and front wall (2') which, when closing the lid, tend to interlock in said cutouts (10), so that said tabs are accessible through holes (11). ) provided on the front (13) and sides (8) of the flap of the lid to release them by pushing simultaneously with the fingers of the hand.

Well then, in accordance with the essence of the invention, experimentally it has been possible to verify that, when actuating said tabs (17) with the fingers of the hand, the pressure exerted can cause the deformation of the container at the level of its mouth.

In order to solve this problem, provision has been made for a folding rectangular sector to emerge from the upper end of the front wall (2'), which determines a second cover or inner cover (14) that has at least one tab (15) that locks into place. a slot (16) provided in the folded area of the main cover (6).

This inner lid (14) in a closed situation adopts a perpendicular arrangement to the perimeter of the mouth of the container, and therefore increases the structural rigidity of said mouth against the efforts exerted by the user's fingers on the tabs (17) that are transmitted directly to said inner cover (14) thus avoiding the mouth of the container is deformed.

Finally, it only remains to point out that, as shown in figures 9 to 12, the container can be designed with different distributions and number of locking tabs (17) and access holes (11), and may include one, two or three of these locking systems, the preferred embodiment being the one shown in figures 1 to 8, although in all cases a second cover or inner cover (14) is included that has at least one tab ( 15) for interlocking in a slot (16) provided in the folded area of the main cover (6) and which allows increasing the rigidity of the container at the level of its mouth, avoiding its deformation in the opening maneuvers of the container.
