DESCRIPCIÓNDESCRIPTION
CONTENEDOR PARA PRODUCTOS ALIMENTICIOSCONTAINER FOR FOOD PRODUCTS
El presente modelo tiene por objeto un contenedor para productos alimenticios.The object of this model is a container for food products.
En particular, el presente modelo se refiere a un contenedor, expositor, de cierre hermético para productos perecederos, en particular para productos alimenticios.In particular, the present model refers to a container, display, hermetically sealed for perishable products, in particular for food products.
Actualmente está muy difundido el uso de contenedores (que cumplen la función de verdaderas bandejas) para la exposición y venta de productos alimenticios, como carne, verdura, fruta, etc., en tiendas y supermercados o hipermercados.Currently, the use of containers (which act as true trays) is very widespread for the display and sale of food products, such as meat, vegetables, fruit, etc., in stores and supermarkets or hypermarkets.
Estas bandejas, en efecto, permiten definir un envase de un producto encerrado en un am biente protegido (gracias al uso, en general, de una película plástica de recubrimiento), eventualmente ya pesado y provisto de su precio de venta.These trays, in effect, make it possible to define a container of a product enclosed in a protected environment (thanks, in general, to the use of a plastic covering film), possibly already weighed and provided with its sale price.
Hasta ahora la realización de esos contenedores siguió dos filosofías diferentes, a saber: - la primera de estas filosofías consiste en realizar el contenedor de una sola pieza y de material plástico a través de un procedimiento de termoformado o inyección en moldes; - la segunda de estas filosofías es la de realizar el contenedor con un material de papel, preferentemente de celulosa, derivado de hojas de cartulina, papel o cartón de diferente gramaje - espesor y de una o varias capas en función del tipo de alimento que deberá contener y de su vida de estantería.Until now, the production of these containers followed two different philosophies, namely: - the first of these philosophies consists of making the container in a single piece of plastic material through a process of thermoforming or injection into molds; - The second of these philosophies is to make the container with a paper material, preferably cellulose, derived from sheets of cardboard, paper or cardboard of different weights - thickness and one or more layers depending on the type of food to be contain and its shelf life.
Generalmente, el producto que se coloca en el vano de cabida del contenedor viene protegido mediante aislamiento del vano con respecto al ambiente externo a través de una barrera aislante asociada al contenedor y creando en la parte interna del vano un ambiente al vacío o un ambiente con atmósfera modificada de protección.Generally, the product that is placed in the compartment of the container is protected by isolating the compartment from the external environment through an insulating barrier associated with the container and creating a vacuum environment or an environment with modified atmosphere of protection.
Esencialmente, la barrera contra gases sirve para mantener dentro del contenedor, por el mayor tiempo posible, la mezcla de gases introducida durante el envasado.Essentially, the gas barrier serves to keep the gas mixture introduced during packaging within the container for as long as possible.
En función de la presión parcial de los gases presentes en el contenedor se tendrá una salida/entrada del gas desde la parte interna hacia la parte externa o en sentido inverso. Depending on the partial pressure of the gases present in the container, there will be a gas outlet / inlet from the inside to the outside or in the opposite direction.
Normalmente la barrera (preferiblemente contra gases y líquidos) se obtiene aplicando al contenedor una delgada película de material plástico, (preferiblemente, sin que ello implique ninguna limitación, material plástico multicapa de un espesor apropiado), que se extiende por encima del producto dispuesto dentro del contenedor, tensada por debajo de los bordes del mismo contenedor y soldada o pegada de manera continua a los bordes del mismo contenedor.Normally the barrier (preferably against gases and liquids) is obtained by applying to the container a thin film of plastic material, (preferably, without implying any limitation, multilayer plastic material of an appropriate thickness), which is extended over the product arranged inside. of the container, tensioned below the edges of the same container and continuously welded or glued to the edges of the same container.
En el caso de contenedores con bordes sumamente planos y lisos, (como, por ejemplo, los citados contenedores plásticos obtenidos mediante termoformado en un molde), la soldadura de la película de manera continua puede realizarse fácilmente, por lo cual el aislamiento del vano interno del contenedor no sólo se puede obtener de manera relativamente fácil, sino que, además, es duradero en el tiempo.In the case of containers with extremely flat and smooth edges, (such as, for example, the aforementioned plastic containers obtained by thermoforming in a mold), the continuous welding of the film can be carried out easily, therefore the insulation of the internal gap Not only can it be obtained relatively easily from the container, but it is also durable over time.
Por el contrario, en el caso de los citados contenedores que, en cambio, se obtienen mediante embutido de una hoja plana de cartón, cartulina u otro material equivalente (de sumo interés para esta exposición), obtener una soldadura de la barrera (una película de plástico con barrera contra gases o líquidos, o tapa rígida) en condiciones de asegurar el cierre hermético del contenedor es mucho más difícil de obtener.On the contrary, in the case of the aforementioned containers that, on the other hand, are obtained by embedding a flat sheet of cardboard, cardboard or other equivalent material (of great interest for this exhibition), obtain a weld of the barrier (a film made of plastic with a barrier against gases or liquids, or a rigid lid) in a position to ensure the hermetic closure of the container is much more difficult to obtain.
De hecho, el proceso de modelado (por ejemplo, por embutido) presenta el inconveniente de los característicos pliegues (o fruncido) superficiales del material que se concentran preponderantemente alrededor de las esquinas espaciales cóncavas delimitadas entre dos paredes laterales contiguas del contenedor y alrededor de las esquinas espaciales convexas delimitadas por el borde del contenedor y las paredes laterales.In fact, the modeling process (for example, by drawing) has the disadvantage of the characteristic surface folds (or gathering) of the material that are concentrated predominantly around the concave spatial corners delimited between two contiguous side walls of the container and around the Convex spatial corners delimited by the edge of the container and the side walls.
Dichos pliegues, en efecto, se deben a plisados y sobreposiciones locales a las cuales el material con que está formado la hoja se debe adaptar para asumir - a partir de una disposición plana - una configuración espacial que, en particular, presenta una superficie lateral curva y/o replegada.Said folds, in effect, are due to local pleats and overlaps to which the material with which the sheet is formed must adapt to assume - from a flat arrangement - a spatial configuration that, in particular, presents a curved lateral surface. and / or folded.
Puesto que tales pliegues podrían conducir a la formación de canales (capilares) de intercomunicación entre el vano interno del contenedor y el ambiente externo circunstante, lograr un cierre hermético en correspondencia de los pliegues es sumamente problemático.Since such folds could lead to the formation of channels (capillaries) for intercommunication between the internal span of the container and the surrounding external environment, achieving a hermetic closure in correspondence of the folds is extremely problematic.
A tal efecto, la parte Solicitante ha desarrollado su propia tecnología que ha sido ilustrada en los documentos de las patentes de invención EP 1365964 y EP 1792844 con la cual se brinda la solución - aparte de a otros problemas que se derivan del refuerzo anular del contenedor - también al problema de cómo obtener un mejor sellado de los contenedores adecuado al uso de los mismos como contenedores estancos de productos alimenticios frescos y/o, de todos modos, muy perecederos por contacto con el aire ambiente.To this end, the Applicant has developed its own technology that has been illustrated in the documents of the patents of invention EP 1365964 and EP 1792844 with which it is provides the solution - apart from other problems arising from the annular reinforcement of the container - also to the problem of how to obtain a better sealing of the containers suitable for using them as watertight containers for fresh food products and / or, anyway , very perishable by contact with ambient air.
Esa tecnología ofrece una mejora a dichos problemas a través de la producción de bordes de refuerzo especiales con conformaciones geométricas especiales aptas para sobreponerse de manera continua y para envolver las partes superiores de las paredes laterales del contenedor para tratar de mejorar el cierre hermético.This technology offers an improvement to these problems through the production of special reinforcing edges with special geometric shapes suitable to continuously overlap and to wrap the upper parts of the side walls of the container to try to improve the hermetic closure.
En la práctica industrial tal solución conocida consiguió resultados satisfactorios sólo en parte para las actuales necesidades de cierre hermético a los gases que exigen una garantía de hermeticidad duradera por un tiempo que dicha solución lo logra satisfacer.In industrial practice, such a known solution achieved satisfactory results only in part for the current gas-tight sealing needs that require a long-lasting guarantee of tightness for a time that said solution is able to satisfy.
El objetivo del presente modelo es el de poner a disposición un contenedor para productos alimenticios en condiciones de obviar los inconvenientes de la técnica conocida citados con anterioridad.The objective of the present model is to make available a container for food products in a position to obviate the drawbacks of the known technique mentioned above.
En particular, el objetivo del presente modelo es el de poner a disposición un contenedor para productos alimenticios en condiciones de combinar la alta resistencia del contenedor de celulosa con una elevada certeza de retención de los gases de embalaje y del producto contenido.In particular, the objective of the present model is to make available a container for food products in a position to combine the high resistance of the cellulose container with a high retention certainty of the packaging gases and of the contained product.
Otro objetivo del presente modelo es el de proponer un contenedor para productos alimenticios de bajo costo, así como elevado gradiente ecológico y de reciclado.Another objective of the present model is to propose a container for low-cost food products, as well as a high ecological and recycling gradient.
Dichos objetivos se logran en su totalidad mediante el contenedor para productos alimenticios objeto del presente modelo, el cual se caracteriza por lo especificado en las reivindicaciones expuestas más adelante.Said objectives are fully achieved by means of the container for food products object of the present model, which is characterized by what is specified in the claims set forth below.
Las características principales del modelo se pondrán aún más de manifiesto a partir de la descripción que sigue de una forma de ejecución preferida, ilustrada solamente a título ejemplificador y no limitativo en los dibujos anexos, en los cuales:The main characteristics of the model will become even more apparent from the following description of a preferred embodiment, illustrated only by way of example and not limiting in the attached drawings, in which:
- la figura 1 ilustra un contenedor para productos alimenticios objeto del presente modelo, en una vista esquemática en planta desde arriba;figure 1 illustrates a container for food products object of the present model, in a schematic plan view from above;
- la figura 2 ilustra el contenedor para productos alimenticios representado en la figura 1 en una vista esquemática lateral;- figure 2 illustrates the container for food products represented in figure 1 in a schematic side view;
- la figura 3 ilustra un detalle del contenedor para productos alimenticios representado en las figuras anteriores según una primera solución de ejecución y en una vista esquemática lateral de despiece;figure 3 illustrates a detail of the container for food products represented in the previous figures according to a first execution solution and in a schematic side exploded view;
- la figura 4 ilustra un detalle del contenedor para productos alimenticios representado en las figuras 1 y 2 según una segunda solución de ejecución y en una vista esquemática lateral de despiece.figure 4 illustrates a detail of the container for food products represented in figures 1 and 2 according to a second execution solution and in a schematic side exploded view.
Con referencia a los dibujos anexos, y en particular haciendo referencia a la figura 1, el contenedor de cierre hermético a gases y líquidos objeto del presente modelo, indicado en su totalidad con el número 100, se utiliza para contener productos perecederos de tipo alimenticio.With reference to the attached drawings, and in particular with reference to Figure 1, the gas and liquid hermetic closure container object of the present model, indicated in its entirety with the number 100, is used to contain perishable food-type products.
Como se puede ver además en las figuras 2, 3 y 4, el contenedor (100) está definido por un envoltorio (1) que comprende una base o fondo (2).As can also be seen in Figures 2, 3 and 4, the container (100) is defined by an envelope (1) comprising a base or bottom (2).
El envoltorio, además, comprende paredes laterales y superior (3) que, combinadas recíprocamente, contornan una cavidad de cabida de productos. Las paredes laterales y superior (3) presentan un borde superior (4) que se extiende con continuidad a lo largo del contorno del envoltorio (1) (ese borde (4) se extiende sobre un plano).The wrapper also comprises side and upper walls (3) that, reciprocally combined, surround a cavity for holding products. The side and upper walls (3) have an upper edge (4) that extends continuously along the contour of the wrapper (1) (that edge (4) extends on a plane).
El envoltorio (1), además, comprende un elemento anular de refuerzo (5) (por ende, también de sostén) asociado de manera de quedar superpuesto y en coincidencia superficial con el borde superior (4) de las paredes laterales y superior (3).The wrapping (1), in addition, comprises an annular reinforcing element (5) (therefore, also supporting) associated in such a way as to be superimposed and in superficial coincidence with the upper edge (4) of the side and upper walls (3 ).
De conformidad con lo ilustrado, el contenedor (100) además comprende una película (6) adherida y asociada al envoltorio (1) que sirve para recubrir completamente la superficie interna del fondo (2), las superficies internas de las paredes laterales y superior (3) y la superficie libre del elemento anular de refuerzo (5) de modo tal de crear una capa o piel de recubrimiento del contenedor (100) para proteger y sellar herméticamente la cavidad de cabida de productos.In accordance with what is illustrated, the container (100) also comprises a film (6) adhered and associated to the wrapper (1) that serves to completely cover the internal surface of the bottom (2), the internal surfaces of the side and upper walls ( 3) and the free surface of the annular reinforcing element (5) in such a way as to create a covering layer or skin of the container (100) to protect and hermetically seal the product storage cavity.
En otras palabras, el contenedor (100) comprende una combinación de componentes en condiciones de mantener y aumentar la rigidez del envoltorio, gracias al elemento anular y un componente con efecto barrera contra gases y líquidos que, también gracias a la presencia del elemento anular, puede ser dispuesto y asociado de manera estable a todas las superficies del envoltorio para lograr una perfecta hermeticidad de toda la cavidad de cabida del contenedor.In other words, the container (100) comprises a combination of components capable of maintaining and increasing the rigidity of the envelope, thanks to the annular element and a component with a barrier effect against gases and liquids that, also thanks to the presence of the annular element, can be arranged and associated in a stable way to all surfaces of the wrapping to achieve a perfect tightness of the entire cavity of the container.
Preferiblemente, la película (6) está hecha de un material plástico elegido de la familia de polímeros termoplásticos (por ejemplo, pero sin que ello implique ninguna limitación, PE, PP, PET) con asociaciones con otros polímeros y/o copolímeros (por ejemplo, pero sin que ello implique ninguna limitación, PA o nylon, EVOH) para obtener una estructura multicapa con efecto barrera contra gases y líquidos.Preferably, the film (6) is made of a plastic material chosen from the family of thermoplastic polymers (for example, but without implying any limitation, PE, PP, PET) with associations with other polymers and / or copolymers (for example , but without implying any limitation, PA or nylon, EVOH) to obtain a multilayer structure with a barrier effect against gases and liquids.
Preferiblemente, la película puede estar hecha con polímeros de fuentes fósiles (compostables o no compostables) o de fuentes renovables (compostables o no compostables) monocapa o multicapa.Preferably, the film can be made with polymers from fossil sources (compostable or non-compostable) or from renewable sources (compostable or non-compostable) monolayer or multilayer.
Preferiblemente, el elemento anular de refuerzo (5) comprende una superficie de intradós (7) replegada contra los bordes de las superficies internas de las paredes laterales y superior (3) y sobre el cual viene adherida la película de recubrimiento (6) (ver las figuras 3 y 4).Preferably, the annular reinforcing element (5) comprises an intrados surface (7) folded against the edges of the internal surfaces of the side and upper walls (3) and on which the covering film (6) is adhered (see Figures 3 and 4).
La presencia de la superficie de intradós permite cubrir de manera lineal los bordes internos de las paredes (3) cubriendo también las zonas de los recodos de las mismas paredes (3) donde se concentran los característicos pliegues superficiales del material durante la formación del envoltorio.The presence of the intrados surface allows the internal edges of the walls (3) to be covered in a linear manner, also covering the areas of the bends of the same walls (3) where the characteristic surface folds of the material are concentrated during the formation of the envelope.
Por consiguiente, gracias a la superficie de intradós se obtiene una superficie lineal con un suave ángulo hacia el restante elemento anular (5) en condiciones de permitir tanto una correcta y segura adhesión de la película (6), con reducidos riesgos de roturas de la película (6) durante su adhesión superficial, como un elevado efecto barrera global del envoltorio (1).Consequently, thanks to the intrados surface a linear surface is obtained with a smooth angle towards the remaining annular element (5) in conditions of allowing both a correct and safe adhesion of the film (6), with reduced risks of breakage of the film (6) during its surface adhesion, as a high overall barrier effect of the wrapper (1).
En aras de lo anterior, el elemento anular de refuerzo (5) además comprende una superficie de extradós (8) sobresaliente hacia fuera desde el borde superior (4) del contenedor (100) y sobre el cual viene adherida la película de recubrimiento (6) (ver la figura 4).For the sake of the foregoing, the annular reinforcing element (5) also comprises an extrados surface (8) projecting out from the upper edge (4) of the container (100) and on which the covering film (6) is adhered ) (see figure 4).
La presencia de la superficie de extradós (8) permite aplicar la película (6) incluso más allá del borde (4) para así, además, poder obtener, de ser necesario, en una o varias de las curvas externas de la superficie una «lengüeta» (11) para facilitar la adhesión y luego la apertura de la bandeja después de haber sido vez sellada herméticamente. The presence of the extrados surface (8) allows the film (6) to be applied even beyond the edge (4) in order to obtain, if necessary, in one or more of the external curves of the surface a « tab »(11) to facilitate the adhesion and then the opening of the tray after it has been hermetically sealed.
