Description

DESCRIPTION

Tray for packaging fruit and vegetable products

TECHNICAL SECTOR

The present invention relates to a tray for packaging products, and more specifically to a tray obtained from a single die-cut sheet of paper or cardboard and provided with folding lines through which a specially designed stackable tray is obtained for use in automated packaging lines.

The object of the invention is to provide a tray that after assembly and stacking is easy to unstack, capable of being closed at the top by means of a sheet of film or paper in an automated manner through conventional heat-sealing machines, with a structure that optimizes its capacity. of load without negatively affecting its stacking/unstacking capacity, structure with ventilation means for the fruit and vegetable products contained within it.

BACKGROUND OF THE INVENTION

In the field of practical application of the invention, the use of trays of a plastic nature is common, which are filled with fruit and vegetable products to be later closed by means of a packaging film.

Obviously the plastic nature of this type of packaging is a major environmental problem, so the use of trays made from paper or cardboard is desirable.

The problem with the trays obtained from paper or cardboard is that they are difficult to handle on automated lines, due to the difficulty involved in unstacking them, to which must be added the complexity involved in the process of sealing the mouth of the the same.

EXPLANATION OF THE INVENTION

The tray for the packaging of fruit and vegetable products that is recommended fully solves the aforementioned problems, based on a simple but effective solution.

For this, the tray of the invention is constituted from the development of a die-cut sheet of paper or cardboard with fold lines, in which a rectangular base or bottom is defined, from each of whose edges respective isosceles trapezoidal sectors emerge. determinants of the larger and smaller side walls of the tray, with the particularity that two inverted triangular sectors emerge from the sides of the larger side walls, which in the assembly of the tray determine a container with a rectangular base and an octagonal mouth, that is to say a container with a divergent configuration in the ascending direction, which facilitates its stacking with other containers of the same type.

At the same time, it has been planned that in this upper area of the larger side walls some small appendages are included that, in the assembly of the box, determine some prominent elements that limit the degree of insertion of a tray when it is stacked on another of the same type, without create large contact areas that can generate friction during unstacking.

More specifically, the inverted triangular sectors are extended by their free lateral edge in tabs through which they will be fixed by gluing to the smaller side walls of the tray, with the special feature that both the larger side walls and the Smaller side walls extend at the top in two sectors that fold outwards and partially overlap each other for fixing, determining a perimeter overhang at the mouth of the tray that determines the fixing means by heat-sealing of the classic sheet of film heat sealable

In accordance with another of the characteristics of the invention, it has been provided that in correspondence with the vertices of the bottom of the tray, the sheet of paper or cardboard includes circular perforations that determine ventilation holes for the product contained within.

These holes are complemented by windows that are determined in the upper confluence area between the larger and smaller side walls, by virtue of the special configuration of the inverted triangular sectors, in which their larger side, instead of being horizontal, is inclined, determining in the assembly in these areas triangular ventilation windows.

The following advantages are derived from this structure:

• Easy automated disengagement of trays when they are stacked after assembly.

• Inclusion of a perimeter overhang or canopy that allows its upper closure by heat sealing with sheets of film or paper in conventional heat sealing machines.

• Paper or cardboard based material, ecological and recyclable.

• Rectangular base and octagonal mouth that optimizes the interior capacity of the tray.

• The perimeter cantilever itself defines a means that facilitates the automatic disengagement of the trays in the warehouse filling chains.

• Means of ventilation of the product contained within, both lower and higher.

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

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, and especially of figure 1, it can be seen how the tray for the packaging of fruit and vegetable products of the invention is constituted from the development of a die-cut paper or cardboard sheet with fold lines, in which a rectangular base or bottom (1) is defined, from each of whose edges emerge respective isosceles trapezoidal sectors determining the larger (2) and smaller (3) side walls.

As has been said previously, although the tray has a rectangular base, its upper mouth is octagonal in configuration, for which two inverted triangular sectors (4) emerge from the sides of the larger side walls (2) that extend laterally in tabs (5) that are fixed by adhesive to the smaller side walls (3), as shown in figures 2 and 3.

Both the larger side walls (2) and the smaller side walls (3) are finished at their upper edge in elongated sectors (6-6') that are wider than the upper edge of said walls, which determines folding elements externally that partially overlap and are fixed together by means of adhesive to determine a perimeter overhang that determines the means of fixing the classic sheet of film or paper heat sealable

Returning again to figure 1, it can be seen how, in correspondence with the vertices of the bottom (1) of the tray, the sheet of paper or cardboard includes circular cut-outs (7) that determine ventilation holes for the product contained within.

Additional ventilation holes (7') have been included on the longitudinal edges that form the bottom (1) and the larger side walls (2).

For their part, the inverted triangular sectors (4) have their upper side (8) inclined, so that when assembled they form triangular windows (9) in correspondence with the vertices of the mouth of the tray.

At the same time, this inclined cut on the upper side (8) determines at the ends of the cantilever that determine the elongated sectors (6-6') a surface of greater amplitude for said cantilever, defining a larger support surface and giving rise to a square mouth with rounded corners.

At the same time, it has been planned that in this upper area of the larger side walls (2) some small appendices (10) are included, with a rounded contour, which in the assembly of the box determine some prominent elements that limit the degree of insertion of a tray in its stacking on another of the same type, without creating large contact areas that can generate friction in unstacking, all as can be seen in figure 4.

Thus, and as Figure 4 shows, the appendages (10) will rest on the ends of the elongated sectors (6-6'), presenting an arched configuration that manages to divert the tensions towards the interior of the container, avoiding concentrating them at the point critical that is generated at the corners via the cut lines.

Claims (2)
