La presente invención se refiere a un envase obturable para productos alimenticios que se pueden verter.The present invention relates to a container sealed for food products that can be poured.

Como es sabido, muchos productos alimenticios que se pueden verter, tales como zumos de frutas, leche UHT (tratada a temperatura ultra-alta), vino, salsa de tomate, etc., son vendidos en envases hechos de material de envasado esterilizado.As is known, many food products that can be poured, such as fruit juices, UHT milk (treated at ultra-high temperature), wine, sauce tomato, etc., are sold in containers made of sterilized packaging

Un ejemplo típico de un tal envase es el envase de forma paralelepipédica para líquidos o productos alimenticios que pueden ser vertidos, conocido como Tetra Brik Aseptic (marca comercial registrada), que es producido plegando y obturando una banda de material envasado estratificada. El material de envasado tiene una estructura de capas múltiples que comprende una capa de base, que comunica resistencia y rigidez al envase, y que puede estar constituida por una capa de material fibroso, por ejemplo papel, o material de polipropileno con carga mineral. La capa de base está cubierta por ambas caras con capas de material termoplástico, por ejemplo películas de polietileno; y, en el caso de envases para productos de almacenaje prolongado, tal como leche UHT, el material de envasado comprende una capa de material de barrera para oxígeno, por ejemplo hoja de aluminio, que se superpone a la capa de material termoplástico, y está a su vez cubierta con otra capa de material termoplástico, que forma finalmente la cara interna del envase en contacto con el producto alimenticio.A typical example of such a container is the container parallelepipedically for liquids or food products that can be poured, known as Tetra Brik Aseptic (brand registered trade), which is produced by folding and sealing a Stratified packaging material band. Packaging material it has a multilayer structure comprising a layer of base, which communicates strength and rigidity to the container, and which can be constituted by a layer of fibrous material, for example paper, or mineral-loaded polypropylene material. The layer of base is covered on both sides with layers of material thermoplastic, for example polyethylene films; and, in the case of containers for prolonged storage products, such as milk UHT, the packaging material comprises a layer of material oxygen barrier, for example aluminum foil, which superimposes the layer of thermoplastic material, and is in turn covered with another layer of thermoplastic material, which forms finally the inner side of the container in contact with the product food

Como es sabido, tales envases son producidos en máquinas de envasado completamente automáticas, en las que se forma un tubo continuo a partir del material de envasado alimentado en banda. La banda de material de envasado es esterilizada en la máquina de envasado, por ejemplo aplicando un agente de esterilización químico, tal como una solución de peróxido de hidrógeno, el cual es eliminado después de la esterilización, por ejemplo vaporizado por calentamiento, de las superficies del material de envasado; y la banda de material de envasado así esterilizada es mantenida en un ambiente estéril cerrado, y es plegada y soldada longitudinalmente para formar un tubo vertical.As is known, such packages are produced in fully automatic packaging machines, in which it is formed a continuous tube from the packaging material fed into band. The packaging material band is sterilized in the packaging machine, for example applying an agent of chemical sterilization, such as a peroxide solution of hydrogen, which is removed after sterilization, by example vaporized by heating, of the surfaces of the packaging material; and the packaging material band as well Sterilized is kept in a closed sterile environment, and is folded and welded longitudinally to form a tube vertical.

El tubo es llenado con el producto alimenticio esterilizado y tratado estéril, y es soldado y cortado transversalmente a lo largo de secciones separadas por igual para formar envases de forma de almohada, los cuales son después plegados mecánicamente para formar los envases acabados, por ejemplo de forma esencialmente paralelepipédica.The tube is filled with the food product sterilized and treated sterile, and is welded and cut transversely along equally separated sections to form pillow-shaped containers, which are after mechanically folded to form the finished containers, for example essentially parallelepipedically.

Alternativamente, el material de envasado puede ser cortado en piezas elementales de partida, que son plegadas en husillos de conformación para formar los envases, los cuales son entonces llenados con el producto alimenticio y obturados. Un ejemplo de este tipo de envase es el envase de "parte superior en tejado de dos aguas", comúnmente conocido por el nombre comercial Tetra Rex (marca comercial registrada).Alternatively, the packaging material can be cut into elementary starting pieces, which are folded into shaping spindles to form the containers, which are then filled with the food product and sealed. A An example of this type of packaging is the "top part" gable roof ", commonly known by name commercial Tetra Rex (registered trademark).

Tales envases están normalmente provistos de dispositivos de apertura cerrables para proteger el producto alimenticio del envase del contacto con agentes externos, y para hacer posible la extracción del producto.Such packages are normally provided with lockable opening devices to protect the product food container contact with external agents, and for make possible the extraction of the product.

Los dispositivos de apertura más comúnmente comercializados actualmente comprenden un marco que define una abertura y aplicado alrededor de una porción retirable o perforable de la pared superior de envase; y una tapa articulada o roscada al marco y que puede ser retirada para abrir el envase. Alternativamente, se pueden usar también otros tipos de dispositivos de apertura, por ejemplo tipos deslizantes.The most common opening devices currently marketed comprise a framework that defines a opening and applied around a removable or perforable portion from the upper container wall; and an articulated or threaded cover to frame and that can be removed to open the container. Alternatively, other types of opening devices, for example sliding types.

La porción retirable del envase puede ser definida, por ejemplo, por un orificio denominado "prelaminado", es decir, un orificio formado en la capa de base del material de envasado antes de que la capa de base sea cubierta con las capas termoplásticas y con la capa de barrera, que cierra el orificio para asegurar la obturación aséptica hermética, mientras que al mismo tiempo se perfora fácilmente.The removable portion of the container can be defined, for example, by a hole called "prelaminated", that is, a hole formed in the layer of base of the packaging material before the base layer is covered with thermoplastic layers and with the barrier layer, which close the hole to ensure airtight aseptic sealing, while at the same time it is easily drilled.

En una solución particularmente ventajosa, descrita en la Solicitud de Patente EP-A-1081054, presentada por la Solicitante de la presente, la tapa del dispositivo de apertura es aplicada, de preferencia soldada por calor, directamente al material termoplástico que cubre el orificio de la capa de base del material de envasado, de manera que, cuando se retira la tapa del marco, la porción retirable permanece unida a la tapa y es desprendida del resto de la pared superior del envase. En otras palabras, el envase es abierto en una operación única por el usuario simplemente separando la tapa del marco para separar simultáneamente la porción retirable.In a particularly advantageous solution, described in the patent application EP-A-1081054, presented by the Applicant hereby, the lid of the opening device is applied, preferably heat welded, directly to the thermoplastic material that covers the hole in the base layer of the packaging material, so that when the lid of the frame, the removable portion remains attached to the lid and is detached from the rest of the top wall of the container. In others words, the container is opened in a single operation by the user simply by separating the cover from the frame to separate simultaneously the removable portion.

Aunque relativamente práctica y barata, la solución anterior deja espacio para mejora adicional, particularmente en lo que se refiere a la apertura del envase. Es decir, puesto que el material de envasado es laminado o estratificado mejor hacia dentro que alrededor del borde de la porción retirable, el material termoplástico que define la zona de borde tiende a rasgarse cuando se retira la tapa del marco, impidiendo así que el producto alimenticio sea vertido suavemente desde el envase, por los restos de plástico desgarrados de la porción retirable, que sobresalen a través del orificio expuesto del material de envasado una vez que la tapa es retirada del marco.Although relatively practical and cheap, the previous solution leaves room for further improvement, particularly as regards the opening of the container. Is that is, since the packaging material is laminated or stratified better inward than around the edge of the removable portion, the thermoplastic material that defines the zone of edge tends to tear when the frame cover is removed, thus preventing the food product from being gently poured from the container, for the torn plastic remains of the removable portion, protruding through the exposed hole of the packaging material once the lid is removed from the framework.

Además, cuando se envasan productos alimenticios particularmente agresivos, tales como zumo de frutas, la cara interior del envase se hace normalmente de materiales termoplásticos con características particulares de densidad, tales como los comúnmente conocidos comercialmente como "metaloceno" y "LK25", los cuales, aunque garantizan envases de buena calidad, incluso en presencia de productos alimenticios agresivos, hacen el envase particularmente difícil de abrir los usando dispositivos de apertura descritos anteriormente.In addition, when food products are packaged particularly aggressive, such as fruit juice, face Inside the container is usually made of thermoplastic materials with particular density characteristics, such as commonly known commercially as "metallocene" and "LK25", which, although guarantee good packaging quality, even in the presence of aggressive food products, they make the container particularly difficult to open using opening devices described above.

Finalmente, en el caso de que el envase, con la porción retirable separada y la tapa puesta hacia atrás encima, se sitúe horizontalmente, por ejemplo sea almacenado para uso posterior en un refrigerador, la absorción continua del producto alimenticio, particularmente si es de naturaleza agresiva, por el borde del orificio del material de envasado, puede dar lugar, después de un periodo relativamente largo (un promedio de ocho horas), a la separación del dispositivo de apertura con respecto al envase y a la fuga del contenido.Finally, in the case that the container, with the Separable removable portion and the lid put back on top, it position horizontally, for example be stored for later use in a refrigerator, the continuous absorption of the food product, particularly if it is aggressive in nature, by the edge of the hole of the packaging material, may result, after a relatively long period (an average of eight hours), at separation of the opening device with respect to the container and the Content leakage.

Es un objeto de la presente invención proporcionar un envase obturado para productos alimenticios que pueden ser vertidos, diseñado para eliminar los inconvenientes anteriormente citados.It is an object of the present invention provide a sealed container for food products that They can be poured, designed to eliminate inconvenience previously cited.

El documento EP 755 862 da a conocer un envase con un pico de apertura por salto de acuerdo con el preámbulo de la reivindicación 1 adjunta.EP 755 862 discloses a package with a jump opening peak according to the preamble of the attached claim 1.

Una realización preferida, no limitativa, de la presente invención, se describirá a modo de ejemplo con referencia a los dibujos que se acompañan, en los cuales:A preferred, non-limiting embodiment of the The present invention will be described by way of example with reference to the accompanying drawings, in which:

La figura 1 muestra una vista en perspectiva de un envase obturado para productos alimenticios que se pueden verter, de acuerdo con la presente invención;Figure 1 shows a perspective view of a sealed container for food products that can be pouring in accordance with the present invention;

La figura 2 muestra una sección transversal a escala mayor de una pared superior del envase de la figura 1 provisto de un dispositivo de apertura cerrable;Figure 2 shows a cross section to major scale of an upper wall of the container of figure 1 provided with a lockable opening device;

La figura 3 muestra un detalle a escala mucho mayor de la figura 2;Figure 3 shows a large scale detail major of figure 2;

La figura 4 muestra la misma vista que en la figura 1, con el dispositivo de apertura en la configuración de abierto.Figure 4 shows the same view as in the Figure 1, with the opening device in the configuration of open.

El número 1 de la figura 1 indica, como un todo, un envase obturado aséptico para productos alimenticios que se pueden verter, por ejemplo un envase de forma paralelepipédica conocido como Tetra Brik Aseptic (marca comercial registrada), que está hecho de material de envasado en lámina 1a como se ha descrito con detalle anteriormente, y está provisto de un dispositivo de apertura cerrable 2 hecho de material plástico y aplicado a una pared superior 3 del envase 1.The number 1 in Figure 1 indicates, as a whole, an aseptic sealed container for food products that they can pour, for example a parallelepipedic container known as Tetra Brik Aseptic (registered trademark), which It is made of sheet packaging material 1a as described in detail above, and is provided with a device of lockable opening 2 made of plastic material and applied to a upper wall 3 of container 1.

El material de envasado 1a, del cual está hecho el envase, tiene una estructura de capas múltiples (figura 3), y comprende una capa de base 5 de material fibroso, por ejemplo papel, o de polipropileno con carga mineral, cubierta, en el lado que define la cara exterior del envase 1, con una película 6 de material termoplástico - en el ejemplo mostrado, polietileno. El lado que define la cara interior del envase 1 tiene una capa 7 de material de barrera para oxígeno, por ejemplo hoja de aluminio, que está cubierta, en el lado enfrentado a la capa 5, con una película 8 de material termoplástico, y, en el lado opuesto, con una capa de adhesivo 9 y una película más 10 de material termoplástico, por ejemplo metaloceno, es decir, polietileno de muy baja densidad (LLDPE), o un material comúnmente conocido comercialmente como "LK25", es decir, polietileno de baja densidad (LDPE). Por lo tanto, la película 10 define la cara interior del envase 1.The packaging material 1a, of which it is made the package has a multilayer structure (figure 3), and it comprises a base layer 5 of fibrous material, for example paper, or of polypropylene with mineral charge, covered, on the side that defines the outer face of the container 1, with a film 6 of material thermoplastic - in the example shown, polyethylene. The side that defines the inner face of the container 1 has a layer 7 of material oxygen barrier, for example aluminum foil, which is cover, on the side facing layer 5, with a film 8 of thermoplastic material, and, on the opposite side, with a layer of adhesive 9 and a film plus 10 of thermoplastic material, for example metallocene, that is, very low density polyethylene (LLDPE), or a material commonly known commercially as "LK25", that is, low density polyethylene (LDPE). For the therefore, the film 10 defines the inner face of the container 1.

El dispositivo de apertura 2 está aplicado a una porción retirable 11 -en el ejemplo mostrado, circular y de eje A- de la pared superior 3 del envase 1, es decir, a una porción separable del resto del envase 1 de manera que pueda ser vertido el producto alimenticio.The opening device 2 is applied to a removable portion 11 -in the example shown, circular and axis A- from the upper wall 3 of the container 1, that is, to a portion separable from the rest of the container 1 so that the food product.

Preferiblemente, la porción retirable 11 se obtiene formando un orificio 12 de eje A a través de la capa 5 de material de envasado 1a, y estratificando la capa 5 con las películas termoplásticas 6, 8, 10 y las capas de barrera y de adhesivo 7, 9 para cubrir el orificio 12.Preferably, the removable portion 11 is obtained by forming a hole 12 of axis A through the layer 5 of packaging material 1a, and layering layer 5 with the thermoplastic films 6, 8, 10 and the barrier and adhesive 7, 9 to cover the hole 12.

Alternativamente, la porción retirable 11 puede comprender también una capa de material para proporcionar rigidez, constituido, por ejemplo, por el mismo material que la capa 5.Alternatively, the removable portion 11 may also comprise a layer of material to provide stiffness, consisting, for example, of the same material as layer 5.

Con referencia particular a las figuras 2 y 4, el dispositivo de apertura 2 comprende un marco anular 15 roscado exteriormente, fijado a la pared 3 del envase 1 en la porción retirable 11, y que define una abertura circular 16 de eje A, a través de la cual es vertido el producto alimenticio; y una tapa 17, que está formada separadamente del marco 15, se rosca al marco 15 a una posición cerrada que cierra la abertura 16 (figura 2), y se adhiere directamente a la porción retirable 11. El envase 1 se abre desenroscando la tapa 17 del marco 15 (figura 4), de manera que la porción retirable 11 permanece unida a la tapa 17 y es separada del resto de la pared 3 del envase 1 para abrir el orificio 12. Una vez abierta, la tapa 17 es movible entre dicha posición cerrada y una posición abierta (figura 4) en la que está separada del marco 15.With particular reference to figures 2 and 4, the opening device 2 comprises a threaded ring frame 15 outwardly, fixed to the wall 3 of the container 1 in the portion removable 11, and defining a circular opening 16 of axis A, to through which the food product is poured; and a lid 17, which is formed separately from frame 15, is threaded to frame 15 to a closed position that closes the opening 16 (figure 2), and is adheres directly to the removable portion 11. The container 1 opens unscrewing the cover 17 of the frame 15 (figure 4), so that the removable portion 11 remains attached to the lid 17 and is separated from the rest of the wall 3 of the container 1 to open the hole 12. Once open, the lid 17 is movable between said closed position and a open position (figure 4) in which it is separated from the frame fifteen.

Más concretamente, el marco 15 comprende esencialmente una pestaña o brida anular 20, de eje A, soldada por calor a la pared 3 del envase 1 y que define interiormente la abertura 16; y una porción anular cilíndrica 21, roscada exteriormente, que sobresale perpendicular y coaxialmente de la cara opuesta de la pestaña 20 a la que está fija a la pared 3.More specifically, frame 15 comprises essentially an annular flange or flange 20, of axis A, welded by heat to the wall 3 of the container 1 and which internally defines the opening 16; and a cylindrical annular portion 21, threaded externally, protruding perpendicularly and coaxially from the face opposite of the tab 20 to the one that is fixed to the wall 3.

La tapa 17 comprende una porción de cierre enteriza 22 para cerrar la abertura 16; y una porción anular cilíndrica 23 roscada interiormente, que sobresale desde el borde periférico exterior circular 24 de la porción 22, y que se rosca sobre la porción anular 21 del marco 15. La tapa 17 comprende también una porción de anclaje anular, cilíndrica, enteriza, 25, que sobresale de la porción de cierre 22, está situada radialmente hacia dentro con respecto a la porción anular 23, se aplica a la abertura de vertido 16 del marco 15 y se fija, por ejemplo se suelda con calor, a la porción retirable 11. Más concretamente, la porción de anclaje 25 está definida por dos elementos anulares concéntricos sobresalientes, muy poco separados.The lid 17 comprises a closing portion integral 22 to close the opening 16; and an annular portion internally threaded cylindrical 23, protruding from the edge circular outer peripheral 24 of portion 22, and which is threaded on the annular portion 21 of the frame 15. The cover 17 comprises also an annular, cylindrical, integral anchor portion 25, protruding from the closure portion 22, is located radially inward with respect to the annular portion 23, it is applied to the pouring opening 16 of frame 15 and is fixed, for example weld with heat, to the removable portion 11. More specifically, the anchor portion 25 is defined by two annular elements Outstanding concentric, very little separated.

La porción de anclaje 25 define, con la porción de cierre 22, una cavidad interior 26 abierta hacia la porción retirable 11 de la pared 3, y, con la porción anular 23 y el borde periférico 24 de la porción de cierre 22, un alojamiento anular 27 para recibir la porción anular 21 del marco 15.The anchor portion 25 defines, with the portion closure 22, an inner cavity 26 open towards the portion removable 11 from the wall 3, and, with the annular portion 23 and the edge peripheral 24 of the closure portion 22, an annular housing 27 to receive the annular portion 21 of the frame 15.

Una característica importante de la presente invención reside en el marco 15, que comprende también una porción de borde 28, la cual sobresale desde la pestaña 20 en el sentido opuesto a la porción anular 21, define la abertura 16 de manera que esté situada radialmente hacia fuera de la porción de anclaje 25 de la tapa 17 y se fija, por ejemplo se suelda por calor, por el extremo, a una zona de borde periférica 11a de la porción retirable 11. Como se muestra en las figuras 2 a 4, la porción de borde 28 cubre el borde del orificio 12 de la capa 5 del material de envasado 1a, y se adhiere por su extremo libre a la porción retirable 11.An important feature of this invention resides in the frame 15, which also comprises a portion edge 28, which protrudes from tab 20 in the direction opposite the annular portion 21, defines the opening 16 so that is located radially out of the anchor portion 25 of the lid 17 and is fixed, for example by heat welding, by the end, to a peripheral edge area 11a of the removable portion 11. As shown in Figures 2 to 4, the edge portion 28 covers the edge of hole 12 of layer 5 of the material of 1st packaging, and adheres at its free end to the portion removable 11.

En el caso de que el envase 1, con la tapa 17 cerrada y la porción retirable separada del resto de la pared 3, se deje en la posición horizontal, se impide así la absorción por el material de envasado 1a que define el borde del orificio 12, junto con cualquier posibilidad de que el dispositivo de apertura 2 resulte desprendido del envase 1.In the case of container 1, with lid 17 closed and the removable portion separated from the rest of the wall 3, is leave in the horizontal position, thus preventing absorption by the packaging material 1a defining the edge of the hole 12, together with any possibility that the opening device 2 It is detached from container 1.

El envase 1 se abre haciendo girar la tapa 17 con respecto al marco 15, de manera que se desenrosque la tapa del marco. A medida que es hecha girar, la tapa 17 retiene la parte de porción retirable 11 soldada a la porción de anclaje 25, desprendiéndola así del resto de pared 3 para abrir el orificio 12. Más concretamente, gracias a que el borde sobresaliente 28 del marco 15 está fijo a la zona de borde periférica 11a de la porción retirable 11, la porción de anclaje 25 de la tapa 17 se fija a una zona más radialmente interior 11b, mejor laminada, de la porción retirable 11, de manera que la apertura del envase 1 es mejorada en gran medida en comparación con envases conocidos, asegurando la retirada limpia del material de envasado 1a a través de la abertura de vertido 16.The container 1 is opened by rotating the lid 17 with respect to frame 15, so that the cover of the framework. As it is rotated, the lid 17 retains the part of removable portion 11 welded to anchor portion 25, thus detaching it from the rest of wall 3 to open the hole 12. More specifically, thanks to the protruding edge 28 of the frame 15 is fixed to the peripheral edge area 11a of the portion removable 11, the anchor portion 25 of the lid 17 is fixed to a portion more radially inner 11b, better laminated, of the portion removable 11, so that the opening of the container 1 is improved by greatly compared to known packages, ensuring the clean removal of packaging material 1a through the opening of discharge 16.

El borde sobresaliente 28 del marco 15 define un elemento de contraste, contra el cual es desgarrado el material que define la porción retirable 11, simplificando así la apertura del envase 1, incluso cuando se usan materiales que son particularmente difíciles de desgarrar, tales como metaloceno y LK25.The protruding edge 28 of the frame 15 defines a contrast element, against which the material that is torn defines the removable portion 11, thus simplifying the opening of the container 1, even when using materials that are particularly difficult to tear, such as metallocene and LK25.

Claramente, se pueden efectuar cambios en el envase 1 según se ha descrito e ilustrado aquí, sin apartarse, sin embargo, del alcance de las reivindicaciones que se acompañan.Clearly, changes can be made to the container 1 as described and illustrated here, without departing, without However, the scope of the appended claims.

En particular, el dispositivo de apertura 2 puede ser aplicado al envase 1 usando otros sistemas de sujeción, por ejemplo sustancias adhesivas, y puede ser de un tipo diferente, por ejemplo comprendiendo una tapa articulada o deslizante con respecto al marco.In particular, the opening device 2 It can be applied to container 1 using other fastening systems, for example adhesive substances, and it can be of a different type, for example comprising an articulated or sliding cover with Regarding the frame.
