Description

DESCRIPTION

Container for fruit and vegetable products.

SECTOR OF THE TECHNIQUE

The present invention relates to a container for fruit and vegetable products, as a boat for the packaging, transport and marketing of products such as fruits and vegetables, without discarding other types of products.

The object of the invention is to provide the market and the general public with a means of packaging that replaces the classic plastic boats.

The package of the invention is obtained in corrugated cardboard, and is only closed superiorly by heat sealing a plastic sheet, thus minimizing the use of this type of contaminant products.

BACKGROUND OF THE INVENTION

In the packaging, transport and marketing of fruit and vegetable products, it is common to use containers or wafers obtained in plastic by molding. Undoubtedly, this material presents as advantages a reduced cost while allowing the visualization of the contents of the container by the consumer. Now, plastic is a material that, as is known, is an important ecological problem, due to the large number of years it needs for its degradation and decomposition. There is therefore a growing need to find alternatives to this type of packaging.

On the other hand, the products contained in this type of trays, can deteriorate or be damaged by the flexibility of the plastic, unless it presents a substantial wall thickness, which means an extra contribution of undesirable material. That is to say, drumsticks or traditionally used containers must guarantee minimum structural resistance that can only be achieved through the use of significant amounts of plastic.

Another drawback is that this type of trays or plastic containers do not allow direct stamping on them of the trademarks or specifications of product that they contain, so it is necessary to resort to these effects, to adhesive labels or girdles also of other materials adding difficulty at the time of recycling.

EXPLANATION OF THE INVENTION

The container for fruit and vegetable products that is recommended solves the problem described above in a satisfactory manner, based on a simple but effective solution.

As mentioned, both consumers and producers are becoming more aware of the negative impact of plastic on the environment. The cardboard container is easier to recycle, making it an ecological material, and the container is smaller and lighter, making it a practical material for transport.

For this, the container of the invention is made of corrugated cardboard, determining in its assembly a boat equipped with wings or perimeter overhang in its upper part that allows the closure by means of a heat-sealed plastic film.

In this way a box with closure is achieved that is perfectly attached to the box and therefore effectively protecting the product contained therein, said product being seen through the transparent plastic film and thus achieving a box that combines the properties of printing and recycling, typical of cardboard, with the advantages of visibility and good protection provided by the plastic closure.

More specifically, the package of the invention is constituted from the development of a corrugated cardboard sheet, stamped and with cut and fold lines, to allow easy assembly and obtain an octagonal contour container, thereby achieving better functionality in Automated filling lines As is well known, rectangular containers make it difficult to move through conveyor belts in automated filling or packaging facilities. Nowadays the processes of packaging of fruit and vegetable products are increasingly automated, working on high-speed production lines with the aim of optimizing yield indices, eliminating human errors and reducing costs. In this type of installation, the containers with curved or chamfered corners (as is the case of the octagonal box object of the invention) have important technical advantages for handling and storage.

The development of the cardboard sheet presents a central sector in functions of the bottom of the container, of rectangular configuration, with its chamfered vertices.

Extensions are formed from the major sides that have to form the major lateral walls, which in turn extend along their lateral ends in two adjacent flaps, one to form the wall corresponding to the chamfer of the octagonal contour, and a flange for fixing to the minor side walls, which emerge from the minor sides of the rectangular base.

Both the major side walls and the minor side walls extend at their upper ends in flaps that in the case assembly fold outwards adopting a horizontal arrangement, which determine a perimetral wing as a cantilever for the mouth of the container, on which the sealing sheet of the container is adhered by heat sealing, such that these flaps extend over the entire perimeter of the mouth of the container, partially overlapping each other, areas in which they are fixed by adhesive.

The sectors that form the minor side walls, in correspondence with the base chamfers, have a slightly trapezoidal configuration, in order to give the package as a whole a stackable and slightly divergent character towards its upper mouth.

Although the package of the invention is preferably and fundamentally provided for the packaging, transport and marketing of fruit and vegetable products, it is equally applicable in other food products.

As an additional advantage, it should be noted that the package is designed in such a way that it can be assembled by machine, including four glue points prior to heat sealing.

It should also mean that the design of the heat sealing flaps is such that they can be mounted and glued in a single machine step.

Also advantageous is the fact that the tub offers high structural strength, as well as easy assembly and bonding.

Another advantage of the package of the invention is that since it is octagonal, there are no sharp edges that can be hit and its advantageous movement in automated high-speed packaging lines.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

Figure 1.- Shows the development in plan of an octagonal container provided with thermosealing flaps for fruit and vegetable products made in accordance with the object of the present invention.

Figure 2.- Shows a perspective view of the properly assembled container.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures outlined, it can be seen how the packaging for fruit and vegetable products is obtained from the development of a corrugated cardboard sheet, stamped with cut and fold lines to allow the assembly of the same, establishing a sector in said development central and rectangular depending on the bottom (1), which has four chamfers (2) alternated with its four sides, forming an octagonal contour.

The bottom (1) has two major sides (3) and two minor sides (4), from which the major (5) and minor (6) walls of the container respectively emerge. From the sides of the major walls (5), inverted trapezoidal sectors (7) emerge which determine in the assembly the walls corresponding to the chamfers (2), sectors (7) which in turn they finish off in respective tabs (8) that, through folding lines (9), are fixed in the assembly by gluing to the smaller side walls (6).

Both the major side walls (5) and the minor side walls (6) are extended by means of the corresponding weakened fold lines (marked in the figure with differentiated lines) in flaps (10) and (11) respectively, than in the armed form a perimeter and horizontal wing or overhang for heat sealing of a plastic sheet that will close the container with the products inside.

The flaps (10) extend slightly over the entire upper edge of the major side walls (5) and partially extend over the edges inverted trapezoidal sectors (7). On the other hand, the flaps (11) have inwardly (11 ') couplings, of width according to the edge of the mouth that determine the inverted trapezoidal sectors (7) corresponding to the chamfers (2), said flaps partially overlapping in zones For gluing.

The size of the flaps (10) and (11) will be the minimum necessary so that an automated assembly with machinery is possible, with four bonding or joining points and then the plastic film can be added by heat sealing.

A relevant feature of the present invention is that the package can be assembled and pasted in two different ways:

- Glueing the tabs (8) to the smaller side walls (6) on the outside, thus leaving the inner surface where the product is free from edges that can damage it and providing a sturdy exterior support point so that at the time of folding the flaps (11), which make up the perimeter wing or cantilever, their horizontality is maintained.

- Glueing the tabs (8) to the minor side walls (6) inside, trying to crush the edges on the die and freeing the outside of the minor side walls (6) to allow a good impression of the brand image or of the technical specifications of the product.

In this way an extremely resistant box is obtained in its assembly, ecological and economic in its production.
