La presente invención se refiere a una bolsa prevista para envasar determinados productos hortofrutícolas, tales como naranjas, limones, patatas, zanahorias, etc., con la finalidad de ser comercializados en la bolsa y transportadas por el propio consumidor desde el establecimiento de venta hasta su domicilio, y lógicamente para el transporte y envasado de esos productos desde el almacén hasta el establecimiento de venta. The present invention relates to a bag intended for packaging certain fruit and vegetable products, such as oranges, lemons, potatoes, carrots, etc., in order to be marketed in the bag and transported by the consumer from the establishment of sale to its address, and logically for the transport and packaging of these products from the warehouse to the establishment of sale.
El objeto de la invención es minimizar la cantidad de material utilizado en la elaboración o fabricación de la bolsa para obtener una reducción de los costos de fabricación, así como para conseguir una elevada resistencia mecánica para poder soportar sin problemas el peso del contenido. The object of the invention is to minimize the amount of material used in the manufacture or manufacture of the bag to obtain a reduction in manufacturing costs, as well as to achieve a high mechanical strength to be able to withstand the weight of the contents without problems.
Es igualmente objeto de la invención proporcionar a la bolsa un asa desplegable para peirnitir el transporte manual con total facilidad. It is also the object of the invention to provide the bag with a folding handle to allow manual transport with ease.
ANTECEDENTES DE T A TNVENCTÓN BACKGROUND FROM T TO TNVENCTÓN
Las bolsas de plástico de estructura reticular que actualmente se fabrican para determinados productos hortofrutícolas, como son naranjas, patatas, etc., se obtienen a partir de un cuerpo tubular de malla que se cierran por sus dos extremos tras el alojamiento del producto en su interior, mientras que en otras ocasiones se parte de una banda continua y laminar que se cierra sobre si misma para configurar el citado cuerpo tubular, a través de una línea longitudinal de soldadura, tras lo que se repite el proceso anteriormente citado. The plastic bags of reticular structure that are currently manufactured for certain fruit and vegetable products, such as oranges, potatoes, etc., are obtained from a tubular mesh body that are closed at its two ends after housing the product inside, while at other times it starts from a continuous and laminar band that closes on itself to configure the said tubular body, through a longitudinal welding line, after The process mentioned above is repeated.
La problemática común a este tipo de bolsas es que el cuerpo de malla está incapacitado para recibir información impresa, la cual es imprescindible en la inmensa mayoría de las ocasiones, ya que sobre la propia bolsa es preciso establecer la marca del producto, características del mismo, código de barras, etc. The problem common to this type of bags is that the mesh body is unable to receive printed information, which is essential in the vast majority of cases, since on the bag itself it is necessary to establish the brand of the product, characteristics of the same , barcode, etc.
El modelo de utilidad español U 9701734 describe una bolsa mediante la que se trata de resolver el problema anteriormente expuesto, para lo cual en dicho modelo de utilidad se utiliza una banda continua estructurada a base de una tira o banda longitudinal intermedia de plástico continuo, de considerable anchura, y susceptible de portar información impresa, complementada con dos franjas laterales, también de plástico, pero de estructura reticular, fijándose entre si las distintas franjas o bandas mediante soldaduras lineales y longitudinales en correspondencia con sus bordes solapados. Esas bandas se complementan con otras dos bandas o tiras de plástico continuas y marginales de menor anchura, destinadas a superponerse por su borde libre y a fijarse entre si mediante una soldadura longitudinal para definir el cuerpo tubular, siendo éste posteriormente fragmentable en sectores o bolsas que se cierran por sus extremos tras recibir en su interior el correspondiente producto. The Spanish utility model U 9701734 describes a bag by means of which the above-mentioned problem is solved, for which in said utility model a structured continuous band is used based on a strip or intermediate longitudinal strip of continuous plastic, of considerable width, and capable of carrying printed information, complemented by two lateral stripes, also of plastic, but of reticular structure, fixing the different strips or bands together by means of linear and longitudinal welding in correspondence with their overlapping edges. These bands are complemented with two other continuous and marginal plastic bands or strips of smaller width, intended to overlap by their free edge and be fixed to each other by means of a longitudinal weld to define the tubular body, this being subsequently fragmentable into sectors or bags that are they close at their ends after receiving the corresponding product inside.
Estas bolsas suelen estar constituidas en dos tipos de materiales, uno de polietileno de baja densidad y otro de polietileno de densidad media, correspondiendo éste a la lámina cerrada y la de polietileno de baja densidad a la malla. These bags are usually made of two types of materials, one of low density polyethylene and another of medium density polyethylene, this corresponding to the closed sheet and low density polyethylene to the mesh.
Pues bien, para que la malla tenga la resistencia adecuada y por su propia naturaleza (polietileno) ha de tener un gramaje mínimo del orden 70gr/m , lo cual trae consigo que la bolsa resulte válida desde el punto de vista teórico, sin embargo no puede ser utilizada para determinados productos, como pueden ser los cítricos, debido precisamente a la cantidad de material que se requiere para la fabricación de la misma. Well, for the mesh to have the appropriate strength and by its very nature (polyethylene) it must have a minimum weight of the order 70gr / m, which brings with it that the bag is valid from the theoretical point of view, however not It can be used for certain products, such as citrus fruits, due precisely to the amount of material required to manufacture it.
Evidentemente este problema se soluciona sin mas que utilizar materiales de alto grado de resistencia, utilizando polipropileno bi-orientado. Obviously this problem is solved without using materials of high resistance, using bi-oriented polypropylene.
No obstante, esta solución en la practica no es viable por cuanto que el polipropileno bi-orientado no es soldable con el polietileno, al menos con el nivel de resistencia mecánica que se hace preciso. However, this solution in practice is not feasible because bi-oriented polypropylene is not weldable with polyethylene, at least with the level of mechanical strength that is required.

REATIZ.ACT N PREFERENTE fiF T,A TNVENCTÓN Como se puede ver en las figuras referidas, la bolsa (1) de la invención, representada en la figura 3, se obtiene a partir de una lámina en la que interviene una banda central de plástico (2) de densidad media, dos bandas, también de plástico y referenciadas con el número (3), fijadas mediante termosoldadura y por parcial solapamiento longitudinal de la banda central (2), estando esas bandas (3) reticuladas y formando respectivas mallas, a las que se unen a su vez otras bandas de plástico marginales o laterales (4) también de baja densidad, es decir de la misma naturaleza y características que la banda central (2). REATIZ.ACT N PREFERRED fiF T, A TNVENCTÓN As can be seen in the aforementioned figures, the bag (1) of the invention, represented in Figure 3, is obtained from a sheet in which a central band of medium density plastic (2), two bands, is involved. also made of plastic and referenced with the number (3), fixed by heat welding and by partial longitudinal overlap of the central band (2), these bands (3) being crosslinked and forming respective meshes, to which other bands are joined of marginal or lateral plastic (4) also of low density, that is to say of the same nature and characteristics as the central band (2).
Sobre las zonas marginales de esas tres bandas, que quedan superpuestas tal como se representa en la figura 2, se fijan a su vez también por superposición respectivas estrechas tiras (7), también de polietileno de densidad media, de manera que al aplicar a la banda continua en su conjunto una presión y un calor en esas zonas de superposición referida, las distintas láminas o franjas y tiras quedan solidariamente unidas por soldadura a través de los espacios vacíos de las bandas reticulares (3). On the marginal areas of these three bands, which are superimposed as shown in Figure 2, they are also fixed by superimposing respective narrow strips (7), also of medium density polyethylene, so that when applied to the As a whole, a pressure and heat continue in these areas of referred overlap as a whole, the different sheets or strips and strips are joined together by welding through the empty spaces of the reticular bands (3).
Evidentemente, las bandas laterales (4) pueden ser de la misma o distinta anchura, para formar una estructuración simétrica o asimétrica. Obviously, the sidebands (4) can be of the same or different width, to form a symmetrical or asymmetrical structure.
Otra característica es que sobre las zonas que han de constituir los puntos correspondientes a las asas de la bolsa obtenida a partir de la lámina o banda referida, se han previsto unos refuerzos (6) con troquelados en "U" próximos y separados entre si, determinando una tira (6') que ha de formar un asa desplegable en el momento de uso de la bolsa (1) obtenida mediante el conveniente plegado longitudinal de la banda original, sus soldaduras y conformación definitiva correspondiente. Another feature is that on the areas that are to constitute the points corresponding to the handles of the bag obtained from the sheet or band referred to, reinforcements (6) with "U" punches are projected and separated from each other, determining a strip (6 ') that must form a folding handle at the time of use of the bag (1) obtained by the convenient longitudinal folding of the original band, its welds and corresponding final conformation.
De esta manera se consigue una bolsa con un gasto de material mínimo y suficientemente resistente para soportar el peso del producto envasado en la misma, utilizando polietileno de densidad media y polipropileno bi-orientado combinadamente, en el primer caso para las bandas de plástico (2 y 4) y en el segundo caso para las bandas reticulares (3), cumpliendo por lo tanto la bolsa en cuestión con todos los objetivos pretendidos, cuales son un gasto mínimo de material para su fabricación, suficiente resistencia para soportar el peso contenido en la misma, óptima fijación por termosoldadura de las distintas bandas que la componen, y el complemento de incorporar un asa desplegable y resistente para el transporte manual de la bolsa con el producto contenido en la misma.. This way you get a bag with a material expense minimum and strong enough to support the weight of the product packaged in it, using medium density polyethylene and bi-oriented polypropylene combined, in the first case for the plastic bands (2 and 4) and in the second case for the reticular bands (3), therefore fulfilling the bag in question with all the intended objectives, which are a minimum expense of material for its manufacture, sufficient strength to withstand the weight contained therein, optimal heat welding of the different bands that the make up, and the complement of incorporating a folding and resistant handle for the manual transport of the bag with the product contained in it.
