Description

DISPOSITIVO DE CIERRE PARA ENVASES DESCRIPCIÓN  CLOSURE DEVICE FOR PACKAGING DESCRIPTION
La presente invención se refiere a un dispositivo de cierre para envases, que permite evitar la entrada de aire al interior del envase incluso de que el envase se haya abierto por primera vez. The present invention relates to a closing device for containers, which allows to prevent the entry of air into the container even if the container has been opened for the first time.
Antecedentes de la invención Background of the invention
Es habitual el uso de envases para contener bebidas o alimentos que están cerrados herméticamente para que las bebidas o alimentos mantengan su calidad y se conserven en perfecto estado hasta su consumo. It is common to use containers to contain drinks or food that are tightly sealed so that the drinks or food maintain their quality and are kept in perfect condition until they are consumed.
Un problema de estos envases es que una vez abiertos por primera vez, los envases no quedan herméticamente cerrados, de manera que la bebida o alimento en el interior del envase debe consumirse dentro de un periodo de tiempo relativamente corto, ya que en caso contrario se estropeará y no se podrá consumir. A problem with these packages is that once opened for the first time, the containers are not hermetically sealed, so that the beverage or food inside the package must be consumed within a relatively short period of time, since otherwise It will spoil and cannot be consumed.
Un ejemplo habitual de este tipo de envase es el denominado Tetra Brik®. Este envase de uso común cuando se abría por primera vez se cortaba una esquina del mismo, de manera que quedaba completamente expuesto a la entrada de aire al interior del envase a través de esta esquina cortada, con lo cual en contenido del envase de debía consumir dentro de un corto periodo de tiempo. A common example of this type of packaging is the so-called Tetra Brik®. This container for common use when it was first opened, a corner of it was cut, so that it was completely exposed to the entry of air into the container through this cut corner, so that the contents of the container should be consumed Within a short period of time.
Para solucionar estos inconvenientes se idearon envases de este tipo con un elemento de cierre articulado, de manera que se retiraba una lengüeta que cubría un orificio para abrir el envase por primera vez, dicho elemento de cierre articulado permitía cerrar el orificio. To solve these inconveniences, packages of this type were conceived with an articulated closure element, so that a tongue was removed that covered a hole to open the container for the first time, said articulated closure element allowed to close the hole.
Aunque esta solución ha permitido alargar el periodo de tiempo para consumir el contenido del envase, en la práctica se ha comprobado que dicho periodo de tiempo puede ser insuficiente, ya que este tipo de cierre permite la entrada de aire al interior del envase. Por lo tanto, es evidente la necesidad de un cierre para envases que evite la entrada de aire en el interior del envase una vez abierto por primera vez, de manera que el contenido del envase pueda consumirse manteniendo sus características originales, durante el máximo tiempo posible. Although this solution has allowed to extend the period of time to consume the contents of the package, in practice it has been proven that said period of time may be insufficient, since this type of closure allows the entry of air into the container. Therefore, it is evident the need for a closure for containers that prevents the entry of air into the interior of the container once opened for the first time, so that the contents of the package can be consumed maintaining its original characteristics, for as long as possible .

La figura 4 es una vista en perspectiva de una segunda realización del dispositivo de cierre para envases de acuerdo con la presente invención en su posición de uso; La figura 5 es una vista en perspectiva de una tercera realización del dispositivo de cierre para envases de acuerdo con la presente invención. Figure 4 is a perspective view of a second embodiment of the closure device for containers according to the present invention in its position of use; Figure 5 is a perspective view of a third embodiment of the closure device for packages according to the present invention.
Descripción de una realización preferida Description of a preferred embodiment
En las figuras 1 a 3 se muestra una primera realización del dispositivo de cierre de acuerdo con la presente invención. A first embodiment of the closure device according to the present invention is shown in Figures 1 to 3.
Como es convencional, un envase 7, por ejemplo un envase de tipo Tetra Brik® comprende un orificio 8 a través del cual puede salir el contenido del envase, por ejemplo una bebida o un alimento líquido. As is conventional, a package 7, for example a Tetra Brik® type container comprises a hole 8 through which the contents of the package can flow out, for example a beverage or a liquid food.
De acuerdo con la presente invención, sobre este orificio 8 está colocado un elemento de cierre 1 , tal como por ejemplo una lengüeta que puede estirarse para su retirada. In accordance with the present invention, a closure element 1 is placed on this hole 8, such as a tongue that can be stretched for removal.
Además, justo por debajo del orificio 8 está colocado un elemento de sellado 2, que está formado a partir de una lámina flexible, por ejemplo una lámina de material plástico, ventajosamente, de polietileno. Furthermore, just below the hole 8 a sealing element 2 is placed, which is formed from a flexible sheet, for example a sheet of plastic material, advantageously, of polyethylene.
Este elemento de sellado 2 está parcialmente unido, por ejemplo en su parte central, al elemento de cierre 1 , tal como se puede apreciar en particular en la figura 2. Esta unión puede realizarse de cualquier manera adecuada, por ejemplo, mediante termosellado. This sealing element 2 is partially attached, for example in its central part, to the closure element 1, as can be seen in particular in Figure 2. This connection can be carried out in any suitable way, for example, by heat sealing.
Cuando se retira el elemento de cierre 1 para abrir el envase por primera vez la unión entre el elemento de cierre 1 y el elemento de sellado 2 hará que este último se deforme, gracias a su naturaleza flexible, definiendo una boca de salida 3, tal como se aprecia mejor en la figura 3. When the closure element 1 is removed to open the container for the first time the joint between the closure element 1 and the sealing element 2 will cause the latter to deform, thanks to its flexible nature, defining an outlet mouth 3, such as best seen in figure 3.
Dicha boca de salida 3 quedará automáticamente cerrada por las características de la lámina que la forma, por ejemplo por la electricidad estática generada por la lámina de manera plástico, haciendo que sus paredes contacten entre sí evitando la entrada de aire al interior del envase. Como se puede apreciar en las figuras, también se ha previsto que el dispositivo de cierre de acuerdo con la presente invención comprenda una tapa 5, que preferentemente está articulada respecto a un marco 6 unido al envase 7 alrededor del orificio 8. Said outlet 3 will be automatically closed by the characteristics of the sheet that forms it, for example by the static electricity generated by the sheet in a plastic manner, making its walls contact each other avoiding the entry of air into the container. As can be seen in the figures, it is also provided that the closure device according to the present invention comprises a lid 5, which is preferably articulated with respect to a frame 6 attached to the container 7 around the hole 8.
En consecuencia, para utilizar el dispositivo de cierre de acuerdo con la presente invención simplemente es necesario estirar del elemento de cierre 3, provocando la creación de la boca de salida 3, que se cerrará automáticamente evitando la entrada de aire al interior del envase 7. Consequently, in order to use the closing device according to the present invention, it is simply necessary to stretch the closing element 3, causing the creation of the outlet mouth 3, which will close automatically preventing the entry of air into the container 7.
Si se desea suministrar el contenido del envase 7, por ejemplo un líquido, se hará de una manera convencional, girando el envase 7 hasta que el contenido salga a través de la boca de salida 3, que se abrirá automáticamente por la presión ejercida por el contenido al salir del envase 7, y después se volverá a cerrar también automáticamente. If it is desired to supply the contents of the container 7, for example a liquid, it will be done in a conventional manner, rotating the container 7 until the content leaves through the outlet 3, which will be automatically opened by the pressure exerted by the content when leaving container 7, and then it will close again automatically.
Como es evidente, el usuario no deberá manipular el dispositivo de cierre de una manera diferente a como lo hace actualmente, ya que el elemento de sellado 2 interactúa con el elemento de cierre 1 al abrir el envase 7 por primera vez y después con el contenido del envase 7 para abrir la boca de salida 3.  As is evident, the user should not manipulate the closing device in a different way from the way it currently does, since the sealing element 2 interacts with the closing element 1 when opening the container 7 for the first time and then with the contents of the container 7 to open the outlet 3.
En la figura 4 se ha representado una realización alternativa respecto a la representada en las figuras 1 a 3. Por motivos de simplicidad se utilizan las mismas referencias numéricas para identificar elementos equivalentes. An alternative embodiment with respect to that represented in Figures 1 to 3 has been shown in FIG. 4. For the sake of simplicity the same numerical references are used to identify equivalent elements.
La única diferencia respecto a la realización anterior es la presencia de unas aletas de retención 4, cuya función es la de retener la boca de salida 3 en su posición orientada hacia arriba, tal como se muestra en la figura 4. The only difference with respect to the previous embodiment is the presence of retention fins 4, whose function is to retain the outlet mouth 3 in its upwardly oriented position, as shown in Figure 4.
Debe indicarse que estas aletas de retención 4 pueden tener cualquier forma adecuada, no necesariamente la representada en la figura 4. It should be noted that these retention fins 4 may have any suitable shape, not necessarily that shown in Figure 4.
En la figura 5 se representa una tercera realización del dispositivo de cierre para envases de acuerdo con la presente invención. Por motivos de simplicidad se utilizan las mismas referencias numéricas para identificar elementos equivalentes. A third embodiment of the closure device for packages according to the present invention is shown in Figure 5. For simplicity reasons They use the same numerical references to identify equivalent elements.
En este caso, la boca de salida 3 de dicho elemento de sellado 2 no está unida al elemento de cierre 1 , que es opcional. Además, la boca de salida 3 está hecha de un elastómero, por ejemplo de silicona. In this case, the outlet 3 of said sealing element 2 is not connected to the closing element 1, which is optional. In addition, the outlet 3 is made of an elastomer, for example silicone.
De esta manera, al verter el contenido del envase 7, la boca de salida 3 se abre automáticamente, igual que en las realizaciones anteriores, y se cerrará por las características elásticas de la boca de salida 3 al dejar de pasar el contenido del envase 7 a través de dicha boca de salida 3. In this way, when pouring the contents of the container 7, the outlet opening 3 opens automatically, as in the previous embodiments, and will be closed due to the elastic characteristics of the outlet opening 3 when the contents of the package 7 stop passing through said outlet 3.
A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el dispositivo de cierre descrito es susceptible de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser sustituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas. Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described closure device is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by others technically equivalent, without departing from the scope of protection defined by the appended claims.
