Banda continua aligerada para la fabricación de bolsas para productos hortofrutícolas y similaresLightened continuous band for the manufacture of bags for horticultural products and similar

Objeto de la invenciónObject of the invention

El objeto de la presente invención es una novedosa banda continua que dispone de ventanas que se cierran mediante fragmentos de material plástico, estos fragmentos tienen una pluralidad de orificios repartidos uniformemente por su superficie.The object of the present invention is a novel continuous band that has windows that are closed by fragments of plastic material, these fragments have a plurality of holes evenly distributed over its surface.

Antecedentes de la invenciónBACKGROUND OF THE INVENTION

Son bien conocidas las bandas continuas para la fabricación de bolsas, mediante la unión de sus bordes longitudinales, para configurar un tubo continuo fragmentable en una pluralidad de sectores correspondiente a respectivas bolsas.The continuous webs for the manufacture of bags are well known, by joining their longitudinal edges, to form a fragmentable continuous tube in a plurality of sectors corresponding to respective bags.

Cuando el producto que contiene las bolsas son productos hortofrutícolas y similares las bolsas han de proporcionar una adecuada aireación de mismo lo que se consigue de muy diferentes maneras, entre las que se pueden citar que el material de la bolsa sea reticular o que la banda disponga de ventanas cerradas usualmente mediante fragmentos de red, estas soluciones también permiten que los consumidores puedan ver el producto envasado.When the product containing the bags are horticultural and similar products, the bags must provide adequate aeration of same which is achieved in very different ways, among which may be mentioned that the bag material is reticular or that the band disposes From closed windows usually through network fragments, these solutions also allow consumers to see the packaged product.

En el caso de bandas reticulares uno de sus inconvenientes es la imposibilidad de incluir ningún tipo de información impresa y otro inconveniente el daño que los filamentos pueda causar al producto. En cambio, la solución que conjuga ventanas y fragmentos de red permite imprimir todo tipo de información y la inspección visual del producto, pero para que la bolsa tenga la necesaria resistencia mecánica el grosor de los filamentos de la red ha de ser bastante grande, lo que implica mayor gasto de productos plásticos y por consiguiente un incremento de costes.In the case of reticular bands one of its drawbacks is the impossibility of including any type of printed information and another inconvenience the damage that the filaments may cause to the product. On the other hand, the solution that conjugates windows and fragments of network allows to print all type of information and the visual inspection of the product, but for the bag to have the necessary mechanical resistance the thickness of the filaments of the network has to be quite large, which implies higher spending of plastic products and therefore an increase in costs.

La presente invención preconiza una banda continua que para cerrar las ventanas incorpora fragmentos de material plástico que disponen de una pluralidad de orificios uniformemente repartidos en toda su superficie, que soluciona los anteriores inconvenientes permitiendo la impresión en las zonas sin ventanas y la inspección visual del producto, además de que el peso de un fragmento material plástico con sus correspondientes orificios que ofrezca la misma resistencia mecánica que un fragmento de red de iguales dimensiones es alrededor un 40% inferior, con lo que hay un ahorro en los materiales utilizados lo que conlleva un ahorro monetario y un menor gasto de productos que son de difícil eliminación cuando se convierten en residuos.The present invention advocates a continuous band that to close the windows incorporates fragments of plastic material that have a plurality of holes uniformly distributed over its entire surface, which solves the above drawbacks allowing printing in areas without windows and visual inspection of the product , in addition to the weight of a plastic material fragment with its corresponding holes that offers the same mechanical strength that a fragment of a network of equal dimensions is around 40% lower, with which there is a saving in the materials used which leads to a monetary saving and a lower spending of products that are difficult to eliminate when they become waste.

Descripción de la invenciónDescription of the invention

La banda continua aligerada para la fabricación de bolsas para productos hortofrutícolas y similares, que es el objeto de la presente invención, consiste en una lámina continua de plástico de anchura igual a la anchura de la mencionada banda, dicha banda dispone en cada uno de los mencionados sectores de una o más ventanas de igual o diferente tamaño; al menos una de las ventanas se cierra mediante un fragmento de material plástico formal y dimensionalmente adecuado a la dicha al menos una ventana y fijado por sus bordes a la periferia de la misma mediante termosoldadura o procedimiento similar, el referido fragmento de material plástico dispone de un pluralidad de orificios troquelados de igual tamaño que están repartidos uniformemente por la superficie del dicho fragmento.The lightened continuous band for the manufacture of bags for horticultural products and the like, which is the object of the present invention, consists of a continuous sheet of plastic of width equal to the width of said band, said band disposes in each of the mentioned sectors of one or more windows of equal or different size; At least one of the windows is closed by means of a fragment of plastic material formally and dimensionally adapted to the said at least one window and fixed by its edges to the periphery of the same by means of thermowelding or similar procedure, said fragment of plastic material having a plurality of punched holes of equal size that are evenly distributed over the surface of said fragment.

Una solución, a primera vista similar, podría ser que la lámina continua careciese de ventanas y troquelar en toda su superficie o en zonas previamente elegidas una pluralidad de orificios, pero esto implicaría, que para obtener una bolsa con la misma resistencia mecánica que la obtenida a partir de la presente invención, que el grosor de la lámina continua de plástico fuese mayor, por lo que el ahorro en material y costes desaparecería además de aumentar los problemas medioambientales generados al desechar las bolsas.A solution, at first sight similar, could be that the continuous sheet lacked windows and die-cut on all its surface or in previously chosen areas a plurality of holes, but this would imply, that to obtain a bag with the same mechanical resistance as that obtained from the present invention, that the thickness of the continuous sheet of plastic was greater, so that the savings in material and costs would disappear as well as increase the environmental problems generated when discarding the bags.
