Description

ENVASE PARA CONSERVAR FRIOS PRODUCTOS  PACKAGE TO KEEP COLD PRODUCTS
OBJETO DE LA INVENCION  OBJECT OF THE INVENTION
La invención se refiere a un envase que está previsto para conservar fríos productos, del tipo de los que presentan una configuración flexible, y que tiene por objeto mantener los productos fríos un mayor tiempo, alargando la conservación de los mismos.  The invention relates to a package that is intended to keep cold products, of the type that have a flexible configuration, and which is intended to keep the products cold for a longer time, lengthening the preservation thereof.
Para ello el envase de la invención comprende dos compartimentos, uno de ubicación de un producto, y otro de ubicación de un elemento frío, de forma que la temperatura del elemento frío se transmite al producto, alargando su conservación .  For this, the package of the invention comprises two compartments, one for the location of a product, and the other for the location of a cold element, so that the temperature of the cold element is transmitted to the product, extending its preservation.
En general la invención es aplicable para envasar cualquier producto que sea susceptible de deterioro por una mala conservación térmica, y más concretamente para el envasado de productos alimenticios en los que sea conveniente mantener el frío ya sea para evitar roturas de la cadena de frío o que el alimento se deteriore como consecuencia de una temperatura excesiva y/o un tiempo de transporte elevado. Más específicamente la invención es aplicable para el transporte de alimentos que exuden líquido, tales como carnes o pescados frescos o congelados, por la impermeabilidad que el envase de la invención presenta .  In general, the invention is applicable to packaging any product that is susceptible to deterioration due to poor thermal preservation, and more specifically for the packaging of food products in which it is convenient to keep the cold either to avoid breaking the cold chain or that the food deteriorates as a result of excessive temperature and / or high transport time. More specifically the invention is applicable for the transport of food that exudes liquid, such as fresh or frozen meat or fish, because of the impermeability that the package of the invention presents.
ANTECEDENTES DE LA INVENCION  BACKGROUND OF THE INVENTION
En el estado de la técnica es conocido el empleo de envases que comprenden dos láminas flexibles y unidas entre sí, formando un alojamiento de productos, que además comprende una embocadura de introducción de dichos productos, y en la que incluye medios de cierre del envase, como por ejemplo se describe en los Modelos de Utilidad españoles con número de solicitud U9803051, U200601636 y U200601859.  In the state of the art it is known to use packages comprising two flexible sheets and joined together, forming a product housing, which also includes an introduction mouth of said products, and which includes means for closing the container, as for example described in the Spanish Utility Models with application number U9803051, U200601636 and U200601859.
Aunque estos envases presentan una configuración que permite el transporte de alimentos tales como carnes o pescados frescos o congelados, dichos envases se ven sometidos a la temperatura ambiente, por lo que en caso de que la temperatura sea elevada y/o el tiempo de transporte sea elevado, el alimento adquiere la temperatura ambiente, lo que puede determinar su descongelación y/o deterioro. Although these packages have a configuration that allows the transport of food such as meats or fresh or frozen fish, these containers are subjected to room temperature, so that in case the temperature is high and / or the transport time is high, the food acquires the room temperature, which can determine its defrosting and / or deterioration.
Ninguno de estos dispositivos permite enfriar el envase, de forma que se alargue la conservación del alimento envasado.  None of these devices allows the container to cool, so that the preservation of the packaged food is lengthened.
DESCRIPCION DE LA INVENCION  DESCRIPTION OF THE INVENTION
Para conseguir los objetivos y resolver los inconvenientes anteriormente indicados, la invención ha desarrollado un nuevo envase para conservar frios productos, que al igual que los previstos en el estado de la técnica comprende una primera y una segunda lámina flexible unidas entre si, de modo que forman un alojamiento de productos que incluye una embocadura para la introducción de los mismos, habiéndose previsto que dicha embocadura esté dotada de medios de cierre para facilitar el transporte y conservación del producto envasado.  In order to achieve the objectives and solve the aforementioned drawbacks, the invention has developed a new package for keeping cold products, which, like those provided in the prior art, comprises a first and a second flexible sheet joined together, so that they form a product housing that includes a mouth for the introduction thereof, it being provided that said mouth is provided with closing means to facilitate transport and preservation of the packaged product.
La principal novedad de la invención reside en el hecho de que comprende una tercera lámina flexible dispuesta entre la primera y segunda lámina flexibles, formando dos compartimentos independientes, uno para ubicar el producto a conservar, y el otro de ubicación de un elemento frió, como por ejemplo puede ser hielo, escarcha o un compuesto químico frío, de forma que la temperatura del elemento frío se transmita al producto envasado, evitando que se rompa la cadena de frío y/o se conserve el producto envasado durante un mayor tiempo.  The main novelty of the invention lies in the fact that it comprises a third flexible sheet disposed between the first and second flexible sheet, forming two independent compartments, one for locating the product to be preserved, and the other for locating a cold element, such as for example, it may be ice, frost or a cold chemical compound, so that the temperature of the cold element is transmitted to the packaged product, preventing the cold chain from breaking and / or keeping the packaged product for a longer time.
En una realización de la invención las tres láminas son de papel, y al menos la cara interior de la primera y segunda lámina, así como al menos una de las caras de la tercera lámina están plastificadas , para mantener estancos los dos compartimentos, lo que impide que el líquido que exudan ciertos alimentos como la carne y el pescado, pase al compartimento en el que se encuentra el elemento frío, y a la inversa, evitando la mezcla de ambos. Evidentemente todas y cada una de las caras de las láminas flexibles pueden estar plastificadas . In one embodiment of the invention, the three sheets are made of paper, and at least the inner face of the first and second sheet, as well as at least one of the faces of the third sheet are plasticized, to keep the two compartments sealed, which prevents the liquid exuding certain foods such as meat and fish, from entering the compartment in which the cold element is located, and conversely, avoiding mixing of both. Obviously, each and every one of the faces of the flexible sheets can be plasticized.
En otra realización de la invención se prevé que al menos una de las tres láminas flexibles sea de plástico, por ejemplo para permitir ver el interior de uno o los dos compartimentos del envase.  In another embodiment of the invention it is envisioned that at least one of the three flexible sheets is made of plastic, for example to allow viewing of the interior of one or both compartments of the package.
La invención prevé que las tres láminas estén unidas por sus laterales formando una bobina continua que se suministra a la dependencia en la que se han de envasar los productos. En este caso se permite a la persona que deba envasar los productos que corte el envase a la medida adecuada. También cabe la posibilidad de que la bobina continua esté dotada de lineas de precorte, para facilitar el corte y la obtención del envase a partir de dicha bobina continua. En cualquiera de estos dos casos, los lados abiertos del envase obtenido a partir de la bobina continua se cierran mediante termosoldado tras realizar el corte e introducir el producto en el interior del envase.  The invention provides that the three sheets are joined by their sides forming a continuous coil that is supplied to the unit in which the products are to be packaged. In this case the person is allowed to pack the products that cut the container to the appropriate extent. It is also possible that the continuous coil is provided with pre-cut lines, to facilitate cutting and obtaining the container from said continuous coil. In either of these two cases, the open sides of the container obtained from the continuous coil are closed by heat welding after cutting and introducing the product inside the package.
Cada uno de los envases obtenidos a partir de una bobina continua, comprende una linea de trepado de configuración en "U" para permitir abrir un orificio a modo de asa que facilite el transporte del producto por parte de un usuario.  Each of the containers obtained from a continuous coil, includes a climbing line of "U" configuration to allow opening a hole as a handle that facilitates the transport of the product by a user.
En la realización preferente de la invención los medios de cierre de la embocadura están determinados por una configuración de las tres láminas flexibles con longitudes diferentes, de forma que se establece en la embocadura un desfase escalonado entre las tres láminas flexibles, en el que la primera y segunda lámina presentan longitudes diferentes y la tercera lámina una longitud intermedia entre las longitudes de la primera y segunda lámina. Para realizar el cierre de esta configuración, bien la cara interior de la primera o segunda lámina de mayor longitud, o la cara exterior de la primera o segunda lámina de menor longitud, están dotadas de una banda adhesiva cubierta mediante una banda de protección, de forma que tras retirar dicha banda de protección y doblar las tres láminas hacia la cara exterior de la primera o segunda lámina de menor longitud, se realiza el pegado de las tres láminas sobre la banda adhesiva, proporcionando un cierre estanco de la embocadura. Para ello la banda debe presentar una anchura suficiente que permita la adherencia de las tres láminas flexibles. In the preferred embodiment of the invention, the closing means of the opening are determined by a configuration of the three flexible sheets with different lengths, so that a stepped gap between the three flexible sheets is established at the opening, in which the first and the second sheet have different lengths and the third sheet has an intermediate length between the lengths of the first and second sheets. To make the closure of this configuration, either the inner face of the first or second sheet of greater length, or the outer face of the first or second sheet of shorter length, are provided with an adhesive strip covered by a protective band, so that after removing said protective band and folding the three sheets towards the outer face of the first or second sheet of shorter length, the three sheets are glued onto the adhesive strip, providing a Watertight closure of the mouth. For this, the band must have a sufficient width that allows the adhesion of the three flexible sheets.
Cabe señalar, que los medios de cierre de la embocadura, asi como de los lados abiertos para el caso en el que el envase esté constituido a partir de una bobina continua, están determinados por las caras plastificadas de las tres láminas, que al aplicarse calor se sueldan realizando el cierre.  It should be noted that the closing means of the mouth, as well as the open sides for the case in which the package is constituted from a continuous coil, are determined by the plasticized faces of the three sheets, which when heat is applied They are welded by closing.
Por lo tanto, mediante la invención se alarga la conservación de los alimentos, y además se evita que puedan entrar en contacto con agua o hielo directamente, lo que podría mermar su calidad.  Therefore, by means of the invention food preservation is lengthened, and it is also avoided that they can come into contact with water or ice directly, which could diminish their quality.
Seguidamente se acompañan una serie de figuras en las que con carácter ilustrativo y no limitativo se ha representado el objeto de la invención.  The following are a series of figures in which the object of the invention has been shown for illustrative and non-limiting purposes.

DESCRIPCION DE LA FORMA DE REALIZACION PREFERIDA  DESCRIPTION OF THE PREFERRED EMBODIMENT
A continuación se realiza una descripción de la invención basada en las figuras anteriormente comentadas.  Below is a description of the invention based on the figures mentioned above.
En una primera realización de la invención, tal y como se muestra en las figuras 1 y 2, el envase comprende una primera lámina flexible 1 y una segunda lámina flexible 2 entre las que se encuentra dispuesta una tercera lámina flexible 3, de forma que las tres láminas 1, 2 y 3 se encuentran unidas entre si por tres de sus lados 6 formando dos compartimentos 4 y 5 independientes entre si a los que se accede a través de una embocadura 7. En la realización del ejemplo las caras de las tres láminas están plastificadas . In a first embodiment of the invention, as shown in Figures 1 and 2, the package comprises a first flexible sheet 1 and a second flexible sheet 2 between which a third flexible sheet 3 is arranged, so that the three sheets 1, 2 and 3 are joined together by three of their sides 6 forming two compartments 4 and 5 independent of each other which are accessed through of a mouth 7. In the embodiment of the example the faces of the three sheets are plasticized.
Esta configuración permite introducir en el compartimento 4 un elemento frió 8, como por ejemplo puede ser escarcha o hielo, y en el compartimento 5 se introduce un producto alimenticio 9, de manera que a continuación se permite efectuar el cierre de la embocadura 7, para lo que la primera lámina 1 tiene una menor longitud que la segunda lámina 2, y la tercera lámina 3 presenta una longitud intermedia entre ambas, estando la cara exterior de la primera lámina 1 dotada de una banda adhesiva 10 cubierta por una banda de protección 11, de modo que tras retirar la banda de protección 11, al doblar la embocadura de las tres láminas 1, 2 y 3, sobre la banda adhesiva 10, se pegan en ella y se produce el cierre de ambos compartimentos a la vez .  This configuration allows a cold element 8 to be introduced into compartment 4, such as frost or ice, and a food product 9 is introduced into compartment 5, so that the closure of the opening 7 is then allowed to close what the first sheet 1 has a shorter length than the second sheet 2, and the third sheet 3 has an intermediate length between them, the outer face of the first sheet 1 being provided with an adhesive strip 10 covered by a protective band 11 , so that after removing the protection band 11, when folding the mouth of the three sheets 1, 2 and 3, on the adhesive band 10, they are glued thereon and both compartments are closed at the same time.
Esta configuración alarga la conservación del alimento 9 por el frió que le transmite el hielo 8.  This configuration extends the preservation of food 9 by the cold transmitted by ice 8.
En otra realización de la invención, tal y como se muestra en la figura 3, el envase es suministrado en una bobina continua 12, que puede incorporar lineas de precorte 13 para facilitar el corte del envase, de forma que una vez realizado dicho corte y tras haber introducido el hielo 8 y alimento 9 en los compartimentos 4 y 5 respectivamente, se realiza el cierre de los lados abiertos del envase mediante termosoldado de las caras plastificadas .  In another embodiment of the invention, as shown in Figure 3, the package is supplied in a continuous coil 12, which can incorporate pre-cut lines 13 to facilitate the cutting of the package, so that once said cutting has been made and After having introduced the ice 8 and food 9 into the compartments 4 and 5 respectively, the closure of the open sides of the package is carried out by heat-sealing the plasticized faces.
Además cada uno de los envases que se obtienen a partir de la bobina 12, pueden incorporar en sus tres láminas 1, 2 y 3 unas lineas de trepado 14 que forman una configuración en "U", de forma que una vez cerrado el envase permita al usuario rasgarla y generar un pequeño hueco a modo de asa para favorecer su transporte de forma manual . In addition, each of the packages obtained from the coil 12, can incorporate in its three sheets 1, 2 and 3 some climbing lines 14 that form a "U" configuration, so that once the container is closed it allows the user tear it and generate a small hollow as a handle to favor its transport manually.
