Description

DESCRIPTION

Prismatic-quadrangular container

TECHNICAL SECTOR

The present invention refers to a container, of the type that, when assembled, has a prismatic-quadrangular configuration, low in height, with multiple applications, from the field of gift packaging to that of fast food packaging.

The object of the invention is to provide a structurally simple container, with a structure in which the waste of material in its stamping is minimized, all with high structural strength and easy access to the interior of the container with a minimum volumetric occupation.

BACKGROUND OF THE INVENTION

Although the scope of practical application of the invention is much broader, the packages of this type that most closely approximate the package of the invention are cardboard packages for pizzas or hot cakes, which, as in the present invention, present a Once assembled a prismatic-quadrangular configuration of low height, but which nevertheless has a wide and varied problem, among which the following aspects should be highlighted:

• When opening, their flap lid takes up a lot of space, so they are not practical in confined spaces.

• The lid does not have sufficient structural integrity, which causes it to bend and come into contact with the food, for which some spacers are usually used that are located in correspondence with the center of the pizza, elements that suppose an additional cost, in addition to constituting totally anti-aesthetic elements.

• In the punching of the box, material is wasted that it would be desirable to minimize.

• They are not suitable for other foods that require minimal ventilation.

EXPLANATION OF THE INVENTION

The prismatic-quadrangular container that is recommended solves in a fully satisfactory way the problems previously exposed in each and every one of the aspects mentioned, based on a simple but highly effective solution.

For this, and more specifically, the container of the invention is constituted from the development of a sheet, preferably of die-cut cardboard, in which a quadrangular central sector is defined, determining the bottom of the box, of whose four edges respective rectangular sectors emerge with a height according to the height of the container, and which will determine its side walls, which are laterally linked to each other between pairs of triangular sectors destined to fold towards the inside of the container, giving continuity to said side walls.

Finally, from the upper edge of each side wall, respective closing tabs emerge, which fold over the central area of the container, with a configuration tending to the triangle, so that two of them, opposite each other, end in correspondence with their free ends. in a pair of tabs that fold towards the bottom of the box, determining a support element on the contents of the same, and provided with an intermediate groove, in which the corresponding tabs in which the others are finished off are intended to fit. two closing tabs.

In this way, instead of presenting a bulky closing lid that in the opening situation is a huge hindrance, the container is closed by means of four smaller tabs, which in the opening situation take up less space, being able to stabilize even without folding completely. out.

On the other hand, the tabs that come together in the central area of the container determine a separating element of the internal surface of the formed lid with respect to the product contained therein, thus preventing it from coming into contact with it.

To facilitate the opening of the container, the tabs destined to be implanted in the last instance in the assembly process of the box, can be assisted by claws that facilitate their uncoupling.

Finally, it only remains to point out that, in correspondence with the hinge lines of the closing tabs with respect to the side walls of the container, arcuate punches can be made in their central area that in the folding of said tabs determine narrow aeration windows , for those products that require this type of performance.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a plan development of a prismatic-quadrangular container made in accordance with the object of the present invention.

Figure 2.- Shows a perspective detail of the container in an intermediate assembly phase.

Figure 3.- Finally, shows a perspective view of the completely assembled 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 the development of a sheet, preferably of die-cut cardboard, in the involving a central quadrangular sector (1) that determines the bottom of the box, whose four edges are prolonged in rectangular sectors (2) of low height, determining the side walls of the box, and that are laterally linked to each other through of pairs of triangular sectors (3) foldable towards the interior of the container.

Superiorly, the rectangular sectors (2) extend through fold lines in closing tabs (4), which have a configuration in which a rectangular lower sector is defined, which extends superiorly in a trapezoidal-isoscelic and majority sector , the upper base of which is finished in turn in a tab (5-5 ') foldable towards the inside of the container.

In correspondence with the intermediate folding zone of the tabs (5) a transverse groove (6) is established which, as can be seen in Figure 2, is intended to receive the tabs (5 ') of the flanges of complementary closure.

These tabs can include a finger (7) in correspondence with the folding area of the tabs (5 ') to facilitate the opening maneuvers of the container.

In this way, the central area of the upper face of the container is substantially reinforced from a structural point of view, with respect to other containers of this type, so that the container closing means themselves determine internally prominent elements, with little volumetry. , but sufficient to prevent the closing tabs from bending into the container beyond their operative closing position.

Finally, to say that, in correspondence with the central area of the folding lines of the closing tabs (4) with respect to the side walls of the container, there can be arched blanks (8) that in the assembly of the container determine narrow windows aeration.

Claims (3)

1§.- Prismatic-quadrangular container, characterized in that it is constituted from the development of a preferably die-cut cardboard sheet, in which a central quadrangular sector (1) participates that determines the bottom of the box, whose four edges extend in rectangular sectors (2) determining the side walls of the box, and which are linked laterally to each other through pairs of triangular sectors (3) folding towards the inside of the container, side walls that extend in correspondence with its upper edge in closing tabs (4) that can be folded over the central area of the container, and of a configuration tending to the triangle, and that are finished in a tab (5-5 ') that can be folded towards the interior of the container, having provided that corresponding to the area intermediate folding of the two opposite tabs (5) a transverse groove (6) is established to receive the other two tabs (5 ') of the complementary closing tabs, m keeping the lid of the packaged product at a distance. 2§.- Prismatic-quadrangular container, according to claim 1§, characterized in that the closing tabs (4) include a lug (7) in correspondence with the folding area of the tabs (5 '). 3§.- Prismatic-quadrangular container, according to claim 1§, characterized in that in correspondence with the central area of the folding lines of the closing tabs (4) with respect to the side walls of the container, arcuate punches are established (8) that in the assembly of the container determine aeration windows.
