Description

Cardboard container.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a package of cardboard that is the type of those that comprise a bottom, some walls lateral, as well as flaps or sectors to be able to assemble the container with the help of adhesive or other means of attachment of the own container.

When these packages are intended primarily to house perishable products in them, their mouthpiece with a heat shrinkable plastic film which hugs the package assembly essentially by its walls lateral, also hugging the edges that limit such walls lateral, said plastic sheet covering the mouth of the container to better protect the product contained in it.

Starting from this premise, the object of the invention is a characteristic package that prevents tears and tears  of the protective film of the packaged product, especially during Freight transport.

Background of the invention

There are currently different types of cartons that comprise all of them in general a bottom and Side walls

In many cases, cardboard containers are complement with a thermo-shrinkable plastic film which is applied on the perimeter of the mouth of the container a once filled with the corresponding product to protect it, being able to exceed the volume defined by the carton itself in correspondence with its mouth.

That plastic film thermo-retractable that hugs the container with the product contained in said container, may suffer damage on all in the live edges of the cardboard container itself, since these songs, after conventional transport operations, can tear said film and thereby reduce the quality requirements, each increasingly demanding, established by the buyer of the product packing.

The tearing and tearing of the plastic film causes the rejection of the container by the user. However for avoid this problem, one solution is to increase the weight of the film plastic up to 30/40% with economic and environmental expenditure That this implies. In addition, this plastic of greater weight adapts worse than one of less weight and also assembled and disassembled from most difficult way.

Description of the invention

In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the The invention proposes a cardboard package that comprises in principle a bottom and side walls.

The bottom is essentially rectangular in shape, although it could also present other forms.

So, considering the rectangular bottom, the container comprises a parallelepiped configuration, counting for this in principle with two minor side walls or front walls and two side walls major or sides.

Starting from this premise, the package is characterized in that the bottom comprises rounded vertices, in correspondence with which internal flaps are arranged that avoid the vertical corners pronounced at 90 ° and that form said internal flaps angles obtuse with respect to the sides and
testeros.

The assembly of the container is ensured by means of outer flaps attached to the inner flaps and which bond by adhesive to two opposite side walls, tearing off the inner flaps of the other pair of side walls opposite.

Other features of the invention are refer to the vertices of the side walls and flaps being rounded off in general to avoid tears in the plastic sheet that will cover the mouth of the container to protect the product contained in said container.

With this arrangement described, a cardboard container to be covered with thermo-plastic film retractable to protect the product contained in said container, from so that said plastic film thanks to the roundings cited strategic will not be torn as it is happening conventionally.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same, some figures are accompanied in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a perspective view of the cardboard container, object of the invention.

Figure 2.- Shows a plan view of a die-cut cardboard plate, from which the container of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the cardboard package comprises in principle a structure parallelepipedic consisting of a rectangular bottom 1 with its free rounded vertices 2, two minor side walls or 3 and two large side walls or 4 side walls, of which ends pull double inner flaps 5 and outer 6, joining the latter by means of adhesive to the heads 3 to assemble the container, while the inner flaps 5 remain arranged in correspondence with the rounded vertices 2 of the bottom 1, then constituting said inner flaps 5 a chamfered corner structure that results in obtuse angles with respect to the front 3 and 4 sides.

The width of sides 4 and front 3 is obviously less than the respective distances between the pairs of minor and major sides of the bottom. So, the bending lines that join the side walls with the bottom they only affect the straight sections of the sides of said bottom without affecting the wide curved vertices 2 of the bottom.

The four vertices of the testeros 3 are finished off  also rounded with a configuration curved-convex 7.

On the other hand, the set of each side 4 and double end flaps 5 and 6 also have vertices curved-convex, 8, 9, 10, 11 and 12, defining the upper edge of the inner flaps 5 according to a curvature curved-convex 13, at whose confluence with ends of the upper edge of the sides 4 a curved-concave bas-relief 14.

At the confluence of edge curvature 13 upper of the internal flaps 5 with respect to the flaps external 6 defines an angular bas-relief 15 of arched branches forming part of the upper edges of said flaps 5 and 6.

On the other hand, at the confluence of the edge lower of the internal flaps 5 and sides 4 another is defined angular bas-relief 16 comprising a short straight branch 17 belonging to sides 4 and a branch curved-convex that constitutes the lower vertex rounded 12 of the inner flaps 5.

The upper free edge of the outer flaps 6 can also present a configuration curved-convex

With this arrangement described, a cardboard container to be covered with a plastic film heat shrink, not shown in the figures, to protect the product contained in said container, so that the plastic film thanks to the strategic roundings These will not be torn as has been the case conventionally.
