Campo técnico de la invenciónTECHNICAL FIELD OF THE INVENTION

La presente invención se refiere a un envase para líquidos, específicamente un envase portable, de tipo tetrabrik, concebido para contener productos alimenticios en estado líquido, contenidos en una bolsa interna desde la que son extraídos evitando en todo momento que entren en contacto con el aire del ambiente, y cuyos productos envasados son extraíbles a través de una embocadura de salida ubicada en posición inferior según el uso normal del envase.The present invention refers to a container for liquids, specifically a portable container, of the tetrabrik type, conceived to contain food products in liquid state, contained in an internal bag from which they are extracted, avoiding at all times that they come in contact with the air of the environment, and whose packaged products are removable through an exit mouth located in inferior position according to the normal use of the container.

El campo técnico en el que se inscribe la presente invención se encuentra comprendido dentro del sector industrial dedicado al envasado de líquidos en contenedores portables, en particular líquidos de consumo tales como agua, zumos, leche, aceite, vino, caldos, u otros de naturaleza equivalente.The technical field in which the present invention is inscribed is comprised within the industrial sector dedicated to the packaging of liquids in portable containers, in particular consumer liquids such as water, juices, milk, oil, wine, broths, or other of nature equivalent.

Antecedentes de la invenciónBACKGROUND OF THE INVENTION

Los envases de tipo tetrabrik son envases de cartón impermeabilizados interiormente, que por lo general adoptan forma prismática de base rectangular, y que están destinados principalmente a contener diversos productos en estado líquido que normalmente suelen consistir en bebidas y alimentos líquidos. El producto del interior está directamente en contacto con la pared interna impermeabilizada del envase de cartón, y la extracción del producto se realiza a través de una embocadura de salida que puede consistir en una zona de la propia base superior del envase con porciones de cartón plegadas que el usuario abre para formar una especie de espita para vertido del producto, o bien puede consistir en una porción de tubo cilíndrico incrustada a través de una de las paredes (a veces en la base superior o a veces en una de las paredes laterales junto a la base superior), que sobresale ligeramente por fuera del envase para presentar una porción externamente roscada a la que se acopla un tapón enroscable/desenroscable por parte del usuario.Tetrabrik-type containers are internally waterproofed cardboard containers, which generally adopt a rectangular-shaped prismatic shape, and which are mainly intended to contain various products in a liquid state that usually consist of beverages and liquid foods. The product of the interior is directly in contact with the inner waterproofed wall of the carton, and the product is extracted through an outlet mouth which may consist of an area of the upper base of the container with folded cardboard portions that the user opens to form a kind of spout for pouring the product, or it may consist of a portion of cylindrical tube embedded through one of the walls (sometimes in the upper base or sometimes in one of the side walls next to the upper base), which protrudes slightly outside the container to present an externally threaded portion to which a screwable / unscrewable cap is attached by the user.

Como se sabe, los productos alimenticios de uso habitual, incluyendo los productos líquidos, tienen una fecha de caducidad a partir de la cual el producto empieza a degradarse. Esta fecha de caducidad está calculada en condiciones de almacenaje óptimas para el producto envasado. Normalmente, en la mayor parte de los casos (por ejemplo, cuando se trata de zumos, leche, vino, aceite o similares), el consumo del producto del interior del envase no se realiza en una sola vez, sino que se realiza en momentos sucesivos, generalmente en uno o varios días, de modo que, aunque se esté dentro del período de caducidad previsto para el producto, no se puede evitar que una vez realizada la primera operación de apertura (y a partir de ahí cada vez que se abre el envase), se produce la entrada de aire del ambiente en el interior del envase, de modo que el producto líquido envasado entra en contacto con el oxígeno del aire del ambiente, lo que indudablemente acelera el proceso de oxidación del producto y la pérdida consiguiente de propiedades organolépticas del mismo. A partir de ese momento, cuanto más tiempo se tarde en agotar el producto, mayor será su deterioro.As is known, commonly used food products, including liquid products, have an expiration date from which the product begins to degrade. This expiration date is calculated under optimum storage conditions for the packaged product. Normally, in most cases (for example, when it comes to juices, milk, wine, oil or similar), the consumption of the product inside the container is not done at once, but is done at moments successive, usually in one or several days, so that, even if it is within the expiration period foreseen for the product, it can not be avoided that once the first opening operation is carried out (and from there every time the container), the ambient air enters inside the container, so that the packaged liquid product comes into contact with the oxygen in the ambient air, which undoubtedly accelerates the oxidation process of the product and the consequent loss of organoleptic properties thereof. From that moment, the longer it takes to exhaust the product, the greater its deterioration.

Es por tanto evidente que sería necesario poder disponer de un envase que garantice que el producto líquido contenido en su interior no va a entrar en contacto con el aire tras la primera apertura del mismo, ni tampoco con las posteriores aperturas sucesivas, de modo que se garantice un mantenimiento óptimo de las propiedades del producto durante el tiempo de uso hasta su agotamiento o mientras dure el período de caducidad. It is therefore evident that it would be necessary to have a container that guarantees that the liquid product contained therein will not come into contact with the air after the first opening thereof, nor with subsequent successive openings, so that guarantee an optimal maintenance of the properties of the product during the time of use until its exhaustion or during the expiration period.

Breve descripción de la invenciónBRIEF DESCRIPTION OF THE INVENTION

De acuerdo con lo anterior, la presente invención está destinada al diseño y la provisión de un envase para líquidos, en particular para líquidos alimenticios, con el que se garantiza el mantenimiento del producto, tras la apertura del envase, durante todo el período hasta la fecha de caducidad merced a que no se produce contacto alguno del producto con el aire del ambiente, y por lo tanto no hay un deterioro acelerado del producto envasado. Para ello, la invención ha previsto la creación de un envase que adopta en general la forma de un envase tetrabrik portable, de tipo habitual, con la particularidad de que en el interior del envase según la invención se aloja una bolsa auto-colapsable, en particular fácilmente colapsable en virtud de estar fabricada con un material plástico de espesor de pared reducido, que contiene el líquido en cuestión (leche, agua, vino, caldos, etc.). La utilización del envase se realiza en posición invertida respecto a lo que es habitual en los envases del estado actual de la técnica, es decir, con la embocadura de salida situada junto a la base de apoyo del envase, consistiendo la embocadura de salida en un tubo hueco que por un extremo distal del tubo está unido, en comunicación de fluido, a la bolsa del interior del envase mediante una unión sellada, hermética, mientras que en relación con el extremo proximal del tubo de salida, éste sobresale ligeramente por fuera del plano de la pared lateral correspondiente mediante una porción roscada que admite el acoplamiento roscado de un tapón de cierre cada vez que se hace uso del envase. De ese modo, la extracción de 5 líquido desde el interior de la bolsa, a través de la embocadura de salida, se realiza sin entrada de aire, reduciéndose el volumen interior de la bolsa en virtud del plegado sobre sí misma en función de la cantidad de líquido extraída, y evitando con ello la puesta en contacto del producto líquido alimenticio con el aire del ambiente. In accordance with the foregoing, the present invention is for the design and provision of a container for liquids, in particular for food liquids, with which the maintenance of the product is guaranteed, after the opening of the container, during the entire period up to the Expiration date thanks to no contact of the product with the ambient air, and therefore there is no accelerated deterioration of the packaged product. For this, the invention has provided for the creation of a container that generally adopts the form of a portable tetrabrik container, of the usual type, with the particularity that inside the container according to the invention a self-collapsible bag is housed, particularly easily collapsible by virtue of being made of a plastic material of reduced wall thickness, which contains the liquid in question (milk, water, wine, broths, etc.). The use of the container is carried out in an inverted position with respect to what is usual in the containers of the current state of the art, that is to say, with the exit mouth located next to the support base of the container, the exit mouthpiece consisting of a a hollow tube which, at a distal end of the tube, is connected, in fluid communication, to the bag inside the container by means of a sealed, sealed connection, while in relation to the proximal end of the outlet tube, it protrudes slightly outside the tube. plane of the corresponding side wall by means of a threaded portion that allows the threaded coupling of a closing plug each time the container is used. Thus, the extraction of liquid from inside the bag, through the outlet mouth, is done without air intake, reducing the interior volume of the bag by virtue of folding on itself depending on the amount of extracted liquid, and thereby preventing the contact of the liquid food product with the ambient air.

Breve descripción de los dibujosBRIEF DESCRIPTION OF THE DRAWINGS

Estas y otras características y ventajas de la invención se pondrán más claramente de manifiesto a partir de la descripción detallada que sigue de una forma de realización preferida de la misma, dada únicamente a título de ejemplo ilustrativo y sin carácter limitativo alguno con referencia a los dibujos que se acompañan, en los que:These and other features and advantages of the invention will be more clearly apparent from the detailed description that follows of a preferred embodiment thereof, given solely by way of illustrative example and without limitation with reference to the drawings. which are accompanied, in which:

La Figura 1 es una representación esquemática, en perspectiva, con la pared delantera parcialmente rasgada, de un envase para productos líquidos de tipo alimenticio, propuesto por la presente invención.Figure 1 is a schematic representation, in perspective, with the front wall partially torn, of a container for food-grade liquid products, proposed by the present invention.

Descripción de una forma de realización preferidaDescription of a preferred embodiment

La forma de realización preferida del envase paras líquidos de la presente invención es según se ha representado en la Figura 1 de los dibujos. El envase comprende un cuerpo 1 portable, de forma general prismática rectangular, en particular un envase de tipo tetrabrik o similar, impermeabilizado internamente (en la Figura 1 aparece parcialmente rasgado por su pared delantera para permitir ver el espacio interno del envase), en cuyo interior se encuentra alojada una bolsa 2 llena con el líquido de consumo, es decir, un líquido alimenticio (agua, vino, leche, aceite, zumo, caldo, etc.) al que está destinado el envase. Tal y como se muestra en la Figura 1, el envase aparece en la posición de uso, es decir invertido con respecto a la forma de uso convencional, con la embocadura de salida situada en posición inferior, junto a la base de apoyo. La embocadura de salida comprende un tubo 3 hueco que accede al exterior a través de una de las paredes laterales del cuerpo 1 del envase, que por su extremo distal (o extremo interno) está unido en comunicación de fluido a la bolsa 2 a través de una unión 3a sellada, mientras que por el extremo proximal (o extremo externo) sobresale ligeramente respecto al plano de dicha pared lateral mediante una porción roscada a la que se encuentra acoplado un tapón 4 de cierre, enroscable y desenroscable manualmente por el usuario. The preferred embodiment of the liquid container for the present invention is as shown in Figure 1 of the drawings. The package comprises a portable body 1, generally rectangular prismatic in shape, in particular a container of type tetrabrik or similar, internally waterproofed (in Figure 1 appears partially torn by its front wall to allow to see the internal space of the container), in which inside is a bag 2 filled with the liquid of consumption, that is to say, a food liquid (water, wine, milk, oil, juice, broth, etc.) to which the container is intended. As shown in Figure 1, the package appears in the position of use, that is to say inverted with respect to the conventional use, with the outlet opening located in the lower position, next to the support base. The outlet mouth comprises a hollow tube 3 which accesses the outside through one of the side walls of the body 1 of the container, which at its distal end (or internal end) is joined in fluid communication to the bag 2 through a sealed junction 3a, while at the proximal end (or external end) slightly protruding from the plane of said side wall by means of a threaded portion to which is attached a closing plug 4, threaded and unscrewed manually by the user.

De acuerdo con esta forma de realización, cuando se desenrosca y retira el tapón 4 del extremo externo del tubo 3, se puede extraer el líquido del interior de la bolsa 2 en la medida que se desee, y una vez extraída la cantidad necesaria, se puede volver a tapar la salida roscando el tapón 4 nuevamente. La ventaja proporcionada por el envase consiste en que, al ser la bolsa 2 contenedora del líquido de un material plástico fácilmente autocolapsable, el vacío generado por la salida del líquido hace que la bolsa se contraiga en el sentido indicado por la flecha F1t impidiendo por tanto que quede libre algún espacio interno que pudiera ocasionar la entrada de aire en el interior de la bolsa 2. De esa manera se garantiza que el líquido del interior de la bolsa 2 no puede entrar en contacto con el aire ambiental y por lo tanto se puede mantener durante toda su duración de caducidad conservando intactas sus propiedades y sin deterioro alguno.According to this embodiment, when the cap 4 is unscrewed and removed from the external end of the tube 3, the liquid can be extracted from the inside of the bag 2 as desired, and once the necessary quantity has been extracted, the you can re-cover the outlet by screwing plug 4 again. The advantage provided by the container is that, as the bag 2 containing the liquid of a plastic material easily self-adhesive, the vacuum generated by the outlet of the liquid causes the bag to contract in the direction indicated by the arrow F1t thus preventing that there be free some internal space that could cause the entry of air into the interior of the bag 2. In this way it is guaranteed that the liquid inside the bag 2 can not come into contact with the ambient air and therefore can be maintain throughout its expiration duration keeping intact its properties and without any deterioration.
