ACCESORIO DE APERTURA-CIERRE PARA ENVASES TIPO BRIK OPENING-CLOSURE ACCESSORY FOR BRIK TYPE CONTAINERS

D E S C R I P C I ÓND E S C R I P C I ÓN

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a un accesorio especialmente concebido para envases tipo brik, como los utilizados en la comercialización de leche, zumos, etc., con el que se consigue seccionar limpiamente el pico vertedor del brik, para apertura del mismo, asi como establecer un cierre estanco del envase, tras su apertura, que se mantiene a lo largo de todo el período de consumo del contenido del envase y que, obviamente, permite la apertura del mismo en las fases de consumo.The present invention relates to an accessory specially designed for brik type containers, such as those used in the marketing of milk, juices, etc., with which it is possible to cleanly section the brik's spout, for opening it, as well as to establish a tight closure of the container, after its opening, which is maintained throughout the entire period of consumption of the contents of the container and which, obviously, allows its opening in the consumption phases.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Co o es sabido, los envases tipo brik adoptan una configuración prismático-rectangular e incorporan, en correspondencia con sus lados menores, "picos" replegados y abatidos, bien sobre sus bases o sobre sus caras laterales, convenientemente fijados a ellas y uno de los cuales es desacoplable para constituir el pico vertedor de vaciado para el contenido del envase.As is known, the brik-type containers adopt a prismatic-rectangular configuration and incorporate, in correspondence with their smaller sides, folded and folded "peaks", either on their bases or on their side faces, conveniently fixed to them and one of the which is decoupling to constitute the pouring spout for the contents of the container.

El previsto como pico vertedor incorpora además una línea de trepado o debilitamiento prevista para el rasgado manual del mismo y consecuente conformación de un orificio de vaciado. Sin embargo, esta solución, perfectamente aceptable desde el punto de vista teórico, presenta en la práctica problemas que se centran fundamentalmente en dos aspectos, por un lado este rasgado resulta en muchas ocasiones dificultoso, bien porque la línea de debilitamiento es deficiente o bien porque la apertura se realiza por niños o personas de avanzada edad, y por otro lado tal rasgado determina bordes irregulares que hacen que también sea irregular la salida del producto.The planned as pouring spout also incorporates a climbing or weakening line provided for the manual tearing of the same and consequent formation of a drain hole. However, this solution, perfectly acceptable from the theoretical point of view, presents in practice problems that focus mainly on two aspects, on the one hand this tearing is often difficult, well because the weakening line is poor or because the opening is done by children or elderly people, and on the other hand such tearing determines irregular edges that also make the product exit irregular.

Esta problemática hace que en la práctica no se utilice siempre este sistema de apertura previsto por los propios envases, recurriéndose habitualmente al uso de tijeras que permiten un corte limpio, pero sin embargo esta herramienta en muchas ocasiones no se encuentra disponible y en cualquier caso constituye un peligro para los niños.This problem means that in practice this opening system provided by the packaging itself is not always used, usually using scissors that allow a clean cut, but nevertheless this tool is often not available and in any case constitutes A danger to children.

Son conocidas también cuchillas especiales acopladas en un elemento plástico en funciones de asa o agarradero, pero al constituir elementos que se mantienen permanentemente independizados del envase presentan la misma problemática que las tijeras, en cuanto a su localización, y agravan el riesgo de accidentes en especial frente a niños.Special blades are also known coupled in a plastic element in functions of handle or handle, but constituting elements that remain permanently independent of the container present the same problem as the scissors, in terms of their location, and aggravate the risk of accidents in particular in front of children

Toda esta problemática ha llevado a una buena parte de los fabricantes que utilizan este tipo de envases, a la utilización de briks provistos en su base superior de un orificio asistido por una tapa abatible, inicialmente precintada, de manera que la apertura resulta sumamente fácil, la boca de vertido queda perfectamente definida, y además permite restablecer el cierre hermético del envase, tras el consumo parcial de su contenido, lo que no es posible con ninguno de los sistemas de apertura anteriormente citados. Sin embargo esta solución, además de no evitar que el producto salga a borbotones, constituye un sistema que resulta muy caro para el fabricante y que crea problemas medioambientales al incorporar mayor cantidad de plástico al envase, que dificulta el reciclaje del mismo.All this problem has led to a good part of the manufacturers that use this type of packaging, to the use of briks provided in its upper base with a hole assisted by a flip-up cover, initially sealed, so that opening is extremely easy, The pouring mouth is perfectly defined, and also allows to restore the hermetic seal of the container, after the partial consumption of its contents, which is not possible with any of the opening systems mentioned above. However, this solution, in addition to not preventing the product from spurting out, constitutes a system that is very expensive for the manufacturer and that creates environmental problems by incorporating more plastic into the container, which makes recycling it difficult.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El accesorio que la invención propone constituye un notable avance tecnológico en este campo, ya que permite seccionar el pico del brik limpiamente, como con una tijera, permite recuperar la situación de cierre estanco para el envase, y además no encarece en absoluto el envasado por cuanto que el accesorio, como su nombre indica, constituye un elemento físicamente independiente del envase, que en un determinado momento puede ser acoplado al mismo y que es reutilizable indefinidamente, por lo que no sólo no incide en absoluto en el costo del envasado sino que su propio costo se ve amortizado con una larga duración en condiciones operativas.The accessory that the invention proposes constitutes a remarkable technological advance in this field, since it allows the brik's peak to be sectioned cleanly, as with a scissor, it allows recovering the sealing situation for the container, and in addition the packaging by since the accessory, as the name implies, constitutes a physically independent element of the package, which at a certain time can be attached to it and that is reusable indefinitely, so that not only does it not affect the cost of packaging at all but its own cost is amortized with a long duration in operating conditions.

El accesorio ofrece además otra serie de ventajas complementarias que se irán haciendo patentes a lo largo de la presente descripción.The accessory also offers another series of complementary advantages that will be patented throughout this description.

De forma más concreta el accesorio que la invención propone está constituido mediante la combinación funcional de una carcasa destinada a acoplarse al pico vertedor del envase tipo brik, y un núcleo interior y giratorio con la doble función de constituir el elemento de corte del pico vertedor y el elemento estrangulador del mismo para cierre estanco tras la apertura.More specifically, the accessory that the invention proposes is constituted by the functional combination of a housing intended to be coupled to the spout tip of the brik type container, and an inner and rotating core with the double function of constituting the cutting element of the spout spout and the throttle element thereof for tight closing after opening.

Más concretamente, la carcasa, hueca y formal y dimensionalmente adecuada para adaptarse a una de las paredes laterales menores del brik, incorpora dos ranuras contrapuestas para introducción del citado pico vertedor, tras su desacoplamiento del cuerpo del envase y tras su disposición horizontal como prolongación de su base superior, de manera que dicho pico vertedor penetra en el seno de la carcasa por la ranura más ancha y emerge sensiblemente al exterior por la ranura más estrecha y contrapuesta.More specifically, the shell, hollow and formal and dimensionally suitable for adapting to one of the minor side walls of the brik, incorporates two opposing grooves for the introduction of said pouring spout, after its decoupling of the container body and after its horizontal arrangement as an extension of its upper base, so that said pouring spout penetrates into the casing the widest groove and emerges noticeably to the outside through the narrowest and opposite groove.

Entre ambas ranuras se establece en el seno de la carcasa un alojamiento que tiende al cilindro y en el que juega el núcleo interno y giratorio, el cual está provisto también de una amplia abertura diametral para paso del pico vertedor, abertura acusadamente divergente de su zona media a sus zonas extremas, situándose en la embocadura externa de dicha abertura una cuchilla que constituye un elemento cortador para seccionamiento del pico del brik, y en su embocadura interna y en oposición a dicha cuchilla, un lomo redondeado destinado a presionar el pico vertedor contra un asiento definido en la carcasa, para establecer el cierre estanco del envase tras su apertura.Between the two grooves, a housing that tends to the cylinder and in which the internal and rotating core plays, which is also provided with a wide diametral opening for passage of the pouring spout, sharply divergent opening of its area, is established within the housing a blade which constitutes a cutting element for sectioning the brik's peak, and in its internal mouth and in opposition to said blade, a rounded spine intended to press the spout against a defined seat in the housing, to establish the tight seal of the container after opening.

El núcleo interior y giratorio cuenta con un brazo que emerge al exterior tras atravesar la carcasa, concretamente a través de un orificio rasgado en el que existen dos estrangulaciones laterales determinantes de tres sectores de estabilización para el citado brazo, un sector extremo correspondiente a una posición del núcleo adecuada para acoplamiento del accesorio al envase, otro sector extremo, contrapuesto al anterior, correspondiente a la situación de corte o apertura, y un sector intermedio correspondiente a la situación de estrangulación del pico y consecuente cierre hermético del envase tras su apertura. El citado brazo presentará un sector elásticamente deformable operativamente enfrentado al orificio rasgado, que le permite el paso de uno a otro de los sectores establecidos en dicho orificio.The inner and rotating core has an arm that emerges to the outside after crossing the housing, specifically through a torn hole in which there are two lateral throttles determining three stabilization sectors for said arm, an end sector corresponding to a position of the core suitable for coupling the accessory to the container, another extreme sector, as opposed to the previous one, corresponding to the cutting or opening situation, and an intermediate sector corresponding to the situation of throttling of the spout and consequent sealing of the container after opening. Said arm will have an elastically deformable sector operatively facing the torn hole, which allows it to pass from one of the sectors established in said hole.

Sólo resta señalar por último que, al objeto de conseguir una óptima funcionalidad del accesorio, tanto la carcasa como el núcleo interior presentarán una superficie discontinua, con un pequeño escalonamiento en su zona media, al objeto de adecuarse formal y dimensionalmente al clásico repliegue o doble cosido central del pico vertedor de estos envases tipo brik.It only remains to point out finally that, in order to achieve optimum functionality of the accessory, both the housing and the inner core will have a discontinuous surface, with a small step in its middle area, in order to formally and dimensionally adapt to the classic folding or double central sewing of the spout peak of these brik type containers.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de estas figuras puede observarse cómo el accesorio que la invención propone está estructurado a partir de una carcasa (1) , de reducidas dimensiones, en la que se establece una cara (2) sensiblemente plana, de acoplamiento a la pared lateral (3) del brik (4) próxima al pico vertedor (5) en el que va a establecerse la apertura del mismo, definiendo en la citada carcasa (1) y en correspondencia con esta cara plana (2) , una amplia ranura transversal (6) a través de la que penetra en su seno el pico vertedor (5) , quedando el borde superior de dicha ranura (6) sensiblemente desfasado hacia afuera con respecto a la superficie plana (2) y definiendo un borde vivo (7) de inserción sobre la base superior del brik (4) , para un mejor acoplamiento del accesorio, como se observa especialmente en la figura 3.In view of these figures, it can be seen how the accessory that the invention proposes is structured from a small-sized housing (1), in which a substantially flat face (2) is established, coupling to the side wall ( 3) of the brik (4) next to the pouring spout (5) in which the opening of the same will be established, defining in the aforementioned housing (1) and in correspondence with this flat face (2), a wide transverse groove (6 ) through which the pouring spout (5) penetrates into its bosom, the upper edge of said groove (6) being substantially offset outward with respect to the flat surface (2) and defining a live edge (7) for insertion on the upper base of the brik (4), for a better coupling of the accessory, as observed especially in figure 3.

La carcasa (1) , que a partir del lateral interno correspondiente a la ranura (6) se estrecha hacia el lateral opuesto, de forma análoga a como lo hace el pico vertedor (5) , se remata por este otro lateral en una segunda ranura (8) , sensiblemente más estrecha que la ranura (6) y posicionada con respecto a esta última de manera que el pico vertedor (5) la sobrepasa sustancialmente, tal como muestra la citada figura 3. En el interior hueco y con tendencia a la configuración cilindrica de la carcasa (1) juega un núcleo giratorio (9) , también tendente a la configuración cilindrica, pero afectado por una amplia abertura diametral y media (10) susceptible de quedar enfrentada a las ranuras (6) y (8) en la posición de acoplamiento del accesorio al brik representada en la repetidamente citada figura 3, ranura (10) que se ensancha acusadamente de su zona media a sus zonas extremas, de manera que en correspondencia con su embocadura externa incorpora una cuchilla (11) , montada sobre un cajeado (12) establecido en el núcleo (9) en posición acusadamente inclinada, tal como se observa especialmente en la figura 4, al objeto de que en el giro del núcleo (9) el corte del pico vertedor (5) se produzca de forma progresiva, para mayor facilidad del mismo.The housing (1), which from the inner side corresponding to the groove (6) narrows towards the opposite side, analogously to the way the pouring spout (5) does, is finished off by this other side in a second groove (8), substantially narrower than the groove (6) and positioned with respect to the latter so that the pouring spout (5) substantially exceeds it, as shown in said figure 3. In the hollow interior and with a tendency to the cylindrical configuration of the housing (1) plays a rotating core (9), also tending to the cylindrical configuration, but affected by a wide diametral and middle opening (10) capable of being faced with the slots (6) and (8) in the coupling position of the accessory to the brik shown in the aforementioned figure 3, slot (10) that widens sharply from its middle to its extreme zones, so that in correspondence with its mouth external incorporates a blade (11), mounted on a recess (12) established in the core (9) in a steeply inclined position, as seen especially in Figure 4, in order that in the rotation of the core (9) the cutting of the pouring spout (5) occurs progressively, for greater ease thereof.

En la embocadura interna de la amplia ranura o abertura diametral (10) del núcleo (9) existe un lomo redondeado (14) que, en otra posición angular para el núcleo (9) , presiona el pico vertedor (5) contra un asiento (14) operativamente establecido en el interior de la carcasa (1) y también visible en la sección de la figura 3.In the internal mouth of the wide slot or diametral opening (10) of the core (9) there is a rounded spine (14) which, in another angular position for the core (9), presses the pouring spout (5) against a seat ( 14) operatively established inside the housing (1) and also visible in the section of figure 3.

De acuerdo con lo anteriormente expuesto el núcleo interior y giratorio (9) es susceptible de adoptar tres posiciones con respecto a la carcasa (1) , para lo cual cuenta con un brazo o accionador (15) exterior a la carcasa (1) , que atraviesa un orificio rasgado (16) de esta última, orificio en cuyos laterales se establecen dos estrangulaciones (17-17') que determinan tres sectores operativos en los que es susceptible de quedar estabilizado el brazo (15) , uno mostrado en la figura 3 y correspondiente a la situación de libre paso para el pico (5) del brik a través del accesorio, otra intermedia y de mayor amplitud, correspondiente a la maniobra de corte con la cuchilla (11) , y una tercera, contrapuesta a la mostrada en la figura 3, en la que el lomo (13) presiona el pico vertedor contra el asiento (14) , estrangulándolo y determinando el cierre estanco del envase, ya abierto.In accordance with the above, the inner and rotating core (9) is capable of adopting three positions with respect to the housing (1), for which it has an arm or actuator (15) external to the housing (1), which crosses a torn hole (16) of the latter, a hole on whose sides two strangulations (17-17 ') are established that determine three operating sectors in which the arm (15) is susceptible to remain stabilized, one shown in Figure 3 Y corresponding to the situation of free passage for the peak (5) of the brik through the accessory, another intermediate and of greater amplitude, corresponding to the cutting maneuver with the blade (11), and a third, opposed to that shown in the Figure 3, in which the spine (13) presses the spout against the seat (14), throttling it and determining the tight seal of the container, already open.

Para conseguir una perfecta estanqueidad en este cierre se ha previsto que el núcleo interior (9) incorpore un pequeño escalonamiento (18) en su zona media, del que es complementario otro existente en el asiento (14) de la carcasa (1) , de manera que dicho escalonamiento coincide posicional y dimensionalmente con el configurado en el pico vertedor (5) del brik por su propio repliegue de cierre.In order to achieve a perfect seal in this closure it is provided that the inner core (9) incorporates a small step (18) in its middle area, of which another existing in the seat (14) of the housing (1), of so that said staggering coincides positionally and dimensionally with that configured in the spout peak (5) of the brik by its own closing fold.

Sólo resta señalar por último que, como se observa en la figura 4, al objeto de facilitar el paso del brazo (15) a través de las estrangulaciones (17-17') del orificio rasgado (16) , se ha previsto que dicho brazo (15) presente un sector (19) enfrentado al orificio rasgado (16) , hueco y elásticamente deformable.It only remains to note finally that, as seen in Figure 4, in order to facilitate the passage of the arm (15) through the throttles (17-17 ') of the torn hole (16), it is provided that said arm (15) present a sector (19) facing the torn hole (16), hollow and elastically deformable.

Como se deduce de la estructuración descrita, el accesorio que la invención propone es pequeño y de fácil manipulación, secciona el pico del brik limpiamente, como una tijera, sin el menor riesgo de accidentes por cuanto que la cuchilla (11) queda totalmente protegida en el seno de la carcasa (1) , y tras la apertura define una boquilla de vertido aplanada, que lamina la salida del producto y evita los clásicos borbotones. Tras dicha apertura permite recuperar un cierre hermético tantas veces como sea necesario. Además el accesorio no repercute en absoluto en el envase, que puede mantener exactamente sus características convencionales y que, en consecuencia, no se ve encarecido en lo más mínimo. Además la carcasa del accesorio puede ser utilizada como soporte publicitario, colaborando de esta manera a minimizar o eliminar su costo frente al usuario.As can be deduced from the described structure, the accessory proposed by the invention is small and easy to handle, it cuts the brik's peak cleanly, like a scissor, without the slightest risk of accidents because the blade (11) is fully protected in The inside of the housing (1), and after opening defines a flattened spout nozzle, which laminates the product outlet and avoids the classic spurts. After this opening allows you to recover a seal as many times as necessary. In addition the accessory does not It has no impact on the packaging, which can maintain exactly its conventional characteristics and, consequently, is not expensive in the least. In addition, the accessory housing can be used as advertising support, thus helping to minimize or eliminate its cost in front of the user.
