The invention provides for the speed and simplicity of this implementation, minimizing production costs and manufacturing time. The invention complies with the maximum health and safety guarantees.

Explicación de la invenciónExplanation of the invention

La invención consiste en un sistema para sorber el líquido contenido en un envase tipo Tetra Brik por medio de una pajita que, situada en el interior del envase y pegada adecuadamente a un sistema de apertura de los que ya existen en el mercado, sale al exterior del envase ayudada por dicho sistema de apertura y permite sorber el líquido de su interior.The invention consists of a system to sip the liquid contained in a Tetra Brik-type container by means of a straw that, located inside the container and properly attached to an opening system of those that already exist on the market, goes outside. of the container aided by said opening system and allows the liquid inside to be sipped.

Las perforaciones, la lámina desprendible, la tapa con precinto o la tapa abatible con pestaña son los sistemas de apertura de los que se ayuda la invención. La realización preferente de la invención necesita que el área a abrir por el sistema de apertura sea la de una ranura de 2 cm aproximadamente de larga y anchura el diámetro de la pajita a utilizar. La formación de un envase tipo Tetra Brik comienza con su desarrollo en un plano. La invención obliga a que el sistema de apertura abra el área de la ranura citada. De este modo, la bobina de material de envasado no sufre modificaciones de interés.The perforations, the removable sheet, the sealable lid or the hinged lid with tab are the opening systems that the invention uses. The preferred embodiment of the invention requires that the area to be opened by the opening system be that of a 2 cm slot. approximately as long and as wide as the diameter of the straw to be used. The formation of a Tetra Brik-type container begins with its development on a plane. The invention forces the opening system to open the area of the aforementioned slot. In this way, the reel of packaging material does not undergo significant modifications.

La invención consiste en tomar una pajita con dos fuelles de unos pocos mm cada uno y separados entre si una pequeña distancia. Esta distancia será la longitud del sellado con adhesivo alimentario de la pajita a uno de los extremos de la ranura. La pajita dejará libre de sellado a un lado el fuelle y lo que reste hasta cubrir los 2cm aproximados de la ranura. Por el lado del otro fuelle, la pajita tendrá longitud suficiente como para alcanzar el fondo del envase una vez fabricado este y terminará en un pico que mejorará la succión.The invention consists of taking a straw with two bellows of a few mm each and separated from each other by a small distance. This distance will be the length of the food adhesive seal from the straw to one end of the slot. The straw will leave the bellows free of sealing on one side and the remainder until the approximate 2cm of the slot is covered. On the side of the other bellows, the straw will be long enough to reach the bottom of the container once it is manufactured and it will end in a spout that will improve suction.

Cuando se accione el sistema de apertura, la pajita saldrá al exterior una longitud de unos 1,5cm, de los cuales la parte no sellada quedará libre del sistema de apertura para permitir la succión, mientras que la parte sellada mantendrá la pajita unida al envase facilitando así al consumidor la tarea de succión.When the opening system is activated, the straw will come out a length of about 1.5cm, of which the unsealed part will be free from the opening system to allow suction, while the sealed part will keep the straw attached to the container thus facilitating the task of suction to the consumer.

It shows the fastening mechanism that incorporates the lid so that once the straw is outside it can be fastened to the closing system in the event that the container has to be closed and opened again because it is not for single consumption.

Realización preferente de la invenciónPreferred embodiment of the invention

Partiendo de las figuras anteriores, se procede a una realización preferente utilizando como sistema de apertura una lámina desprendible que no se llega a separar completamente del Brik.Starting from the previous figures, we proceed to a preferred embodiment using a removable sheet as an opening system that cannot be completely separated from the Brik.

La cara superior de un envase tipo Tetra Brik (Figura 1) tendrá una ranura de unos 2cm aproximadamente de larga y anchura el diámetro de la pajita a utilizar y se situará en la dirección que se considere más apropiada Esta ranura se haría con la misma técnica con la que se hace el círculo que en la actualidad se perfora con la pajita que se encuentra en la bolsita pegada al Brik. El área de esta ranura es la que abrirá la lámina desprendible del exterior.The upper face of a Tetra Brik-type container (Figure 1) will have a slot approximately 2cm long and wide, the diameter of the straw to be used and it will be located in the direction considered most appropriate This slot would be made with the same technique used to make the circle that is currently pierced with the straw found in the bag attached to the Brik. The area of this slot is the one that will open the peelable sheet from the outside.

La pajita que se utiliza (Figura 2) tiene dos fuelles separados entre sí unos 0,5cm aproximadamente. Cada fuelle tiene una longitud de unos pocos mm. La pajita deja a un lado del fuelle aproximadamente 1,5cm y al otro lado la longitud suficiente como para alcanzar el fondo del envase una vez fabricado éste y termina en pico para una mejor succión.The straw used (Figure 2) has two bellows separated from each other by approximately 0.5cm. Each bellows is a few mm long. The straw leaves approximately 1.5cm on one side of the bellows and on the other side enough length to reach the bottom of the container once it is manufactured and ends in a beak for better suction.

Los 0,5cm que separan los dos fuelles de la pajita irán sellados con adhesivo alimentario a uno de los extremos de la ranura que abrirá la lámina desprendible (Figura 3). Los 1,5cm restantes quedan libres justo por debajo del resto del área ocupada por la ranura Esta longitud libre puede ser, si se desea, un poco mayor que la longitud de la ranura para que al accionarse el sistema de apertura, la pequeña dificultad que encuentra a su salida la pajita haga que el fuelle la separe del sistema de apertura y facilite la succión. Ésta es la situación antes de accionar el sistema de apertura Al abrir la ranura con la lámina desprendible, la Figura 4 muestra el interior del envase, la lámina desprendible que abre la ranura y que en este modo de realización sigue pegada al envase, la posición de la pajita tras la apertura con los 1,5cm aproximadamente de longitud libres que permiten la succión, su sellado al envase para facilitar dicha succión así como su terminación en pico en el fondo del Brik que ayuda a la extracción total del líquido de su interior.The 0.5cm that separates the two bellows of the straw will be sealed with food grade adhesive at one of the ends of the slot that will open the removable sheet (Figure 3). The remaining 1.5cm remain free just below the rest of the area occupied by the slot. If desired, this free length can be a little greater than the length of the slot so that when the opening system is activated, the small difficulty that finds the straw at its exit make the bellows separate it from the opening system and facilitate suction. This is the situation before activating the opening system. When opening the slot with the removable sheet, Figure 4 shows the inside of the container, the removable sheet that opens the slot and which in this embodiment continues to be attached to the container, the position of the straw after opening with the approximately 1.5cm free length that allows suction, its sealing to the container to facilitate said suction as well as its peak termination at the bottom of the Brik that helps to fully extract the liquid from inside .

La operación de sellado de la pajita a la cara interior de la ranura del envase con material adhesivo alimentario y la colocación de la lámina desprendible se realizarán en los instantes que se considere oportuno dentro del recorrido que hace la banda del material de envasado en el proceso de formación del envase tipo Tetra Brik.The operation of sealing the straw to the inner face of the slot of the container with food adhesive material and the placement of the removable sheet will be carried out at the moments considered appropriate within the route made by the band of packaging material in the process. formation of the Tetra Brik-type container.

La realización preferente descrita es para envases Tetra Brik de tamaño pequeño y/o mediano. The preferred embodiment described is for small and/or medium-sized Tetra Brik containers.

Otro ejemplo de realización de la invención es para envases tipo Tetra Brik de tamaño mediano que tienen tapa con precinto o tapa abatible con pestaña como sistemas de apertura. Con ello se consigue la aplicabilidad de la invención también a los envases medianos evitando así el uso del tapón. Este modo de realización resolvería el problema del espacio que ocupan los tapones, el de la dificultad de apilamiento y transporte, al mismo tiempo que reduciría la cantidad de plástico del envase, su precio y el impacto medioambiental. Este ejemplo de realización permitiría consumir el líquido del interior del envase en varios usos.Another example of embodiment of the invention is for medium-sized Tetra Brik-type containers that have a sealable lid or a hinged lid with a tab as opening systems. With this, the applicability of the invention is also achieved to medium-sized containers, thus avoiding the use of the cap. This embodiment would solve the problem of the space occupied by the caps, the difficulty of stacking and transportation, while at the same time reducing the amount of plastic in the container, its price, and the environmental impact. This exemplary embodiment would allow the liquid inside the container to be consumed in various uses.

Otro ejemplo de realización es para envase con perforaciones. Another example of embodiment is for a container with perforations.

Claims (4)

REIVINDICACIONES 1. Envase tipo Tetra Brik con pajita interior caracterizado porque en su cara superior se dispone como sistema de apertura una lámina desprendióle (pero que no se separa completamente del envase) que abrirá el área de una ranura de unos 2cm de largo aproximadamente y de ancho el diámetro de la pajita (1). Esta ranura se situará en la dirección que se considere más apropiada en la fabricación del envase En el interior del envase habrá una pajita con dos fuelles de unos pocos mm cada uno y separados entre sí unos 0,5cm. Al otro lado de uno de los fuelles habrá una longitud de unos 1,5cm aproximadamente y al otro lado del segundo fuelle una longitud suficiente como para alcanzar el fondo del envase una vez fabricado éste. La pajita terminará en pico para una mejor succión (2). Los 0,5cm son sellados con adhesivo alimentario a uno de los extremos de la ranura que abrirá la lámina desprendible El fuelle y los 1,5cm restantes quedan libres por debajo del resto del área de la ranura (3). Esta longitud que queda libre puede ser incluso un poco mayor que la longitud de la ranura para que al accionarse el sistema de apertura, la pequeña dificultad que encuentra a su salida la pajita haga que el fuelle la separe del sistema de apertura y facilite la succión. Cuando la lámina desprendible abre la ranura, la pajita sale al exterior con una longitud suficiente para permitir la succión al tiempo que se mantiene sujeta al envase facilitando así la succión de todo el líquido que hay en su interior (4).1. Tetra Brik-type container with an inner straw characterized in that on its upper face there is a detachable sheet as an opening system (but that does not completely separate from the container) that will open the area of a slot approximately 2 cm long and wide the diameter of the straw (1). This slot will be located in the direction that is considered most appropriate in the manufacture of the container. Inside the container there will be a straw with two bellows of a few mm each and separated from each other by about 0.5 cm. On the other side of one of the bellows there will be a length of approximately 1.5cm and on the other side of the second bellows a sufficient length to reach the bottom of the container once it has been manufactured. The straw will end in a peak for better suction (2). The 0.5cm is sealed with food grade adhesive at one end of the slot that will open the removable sheet The bellows and the remaining 1.5cm remain free below the rest of the slot area (3). This free length can even be a little greater than the length of the slot so that when the opening system is activated, the slight difficulty encountered by the straw causes the bellows to separate it from the opening system and facilitate suction. . When the removable sheet opens the slot, the straw comes out long enough to allow suction while remaining attached to the container, thus facilitating the suction of all the liquid inside (4). 2. Envase tipo Tetra Brik con pajita interior, según reivindicación 1, caracterizado porque en lugar de considerar una lámina desprendible considera perforaciones como sistema de apertura.2. Tetra Brik-type container with an inner straw , according to claim 1, characterized in that instead of considering a detachable sheet, it considers perforations as an opening system. 3. Envase tipo Tetra Brik con pajita interior, según reivindicación 1, caracterizado porque la lámina desprendible se desprende completamente del envase. En este ejemplo de realización el sellado de los 0,5cm de la pajita al interior del envase se hará justo antes de la ranura. En esta realización de la invención será necesario otro pequeño punto de sellado entre el fuelle o los 1,5cm y la parte interior de la ranura para que la lámina desprendible ayude a la pajita a salir. En ese movimiento la pajita saldrá al exterior, se soltará de la lámina desprendible que a su vez también se desprenderá del envase al tiempo que los 0,5cm sellados mantendrán la pajita sujeta al envase (5).3. Tetra Brik-type container with an inner straw, according to claim 1, characterized in that the removable sheet is completely detached from the container. In this example of an embodiment, the sealing of the 0.5 cm of the straw inside the container will be done just before the slot. In this embodiment of the invention another small sealing point will be necessary between the bellows or 1.5cm and the inside of the groove for the peelable sheet to help the straw out. In this movement, the straw will come out, it will be released from the removable sheet, which in turn will also come off the container while the sealed 0.5cm will keep the straw attached to the container (5). 4. Envase tipo Tetra Brik con pajita interior , según las reivindicaciones 1 y 3, caracterizado porque el sistema de apertura es una tapa con precinto o una tapa abatible. Dado que estos envases suelen ser de tamaño mediano o grande y llevan una lámina desprendible que se separa completamente del mismo, habría que incorporar una sencilla abrazadera a la tapa con precinto o a la tapa abatible para que sujete a la pajita y evite que ésta se introduzca en el envase en caso de que el vaciado de dicho envase no se haga en una sola vez (6). 4. Tetra Brik-type container with an inner straw, according to claims 1 and 3, characterized in that the opening system is a sealable lid or a hinged lid. Since these containers are usually medium or large in size and have a removable sheet that is completely separated from it, a simple clamp would have to be incorporated into the sealable lid or the hinged lid to hold the straw and prevent it from entering in the container in the event that the emptying of said container is not done in one go (6).
