Description
DESCRIPCIÓNDESCRIPTION
Un cierre para cerrar un recipienteA closure to close a container
La presente invención se refiere a un cierre para tapar recipientes, tales como botellas o similares.The present invention refers to a closure for covering containers, such as bottles or the like.
Son conocidos dos tipos diferentes de tapado para botellas fabricadas de material plástico, en particular botellas destinadas a contener leche, yogur o productos similares: cierres resellables y no resellables.Two different types of capping are known for bottles made of plastic material, in particular bottles intended to contain milk, yoghurt or similar products: resealable and non-resealable closures.
Los tapones corona o de rosca pertenecen al primer tipo, mientras que los cierres u opérculos fabricados de aluminio pertenecen al segundo tipo. En este último caso, la botella también puede estar provista de un tapón de rosca que se va a colocar sobre el cierre, de modo que una vez que se ha retirado éste, la botella todavía se pueda cerrar. La elección de usar un tapón de rosca además de un cierre depende a menudo del volumen de la botella, es decir, si esta última no es del tipo monodosis.Crown or screw caps belong to the first type, while closures or operculums made of aluminum belong to the second type. In the latter case, the bottle can also be provided with a screw cap to be placed on the closure, so that once the closure has been removed, the bottle can still be closed. The choice to use a screw cap in addition to a closure often depends on the volume of the bottle, that is, if the latter is not of the single-dose type.
Es evidente que, en todos los casos, tanto si el cierre es un tapón como si es un cierre, debe proporcionar un sellado perfecto, para garantizar la esterilidad en el interior del envase hasta la apertura inicial.It is evident that, in all cases, whether the closure is a stopper or a closure, it must provide a perfect seal, to guarantee sterility inside the container until the initial opening.
En el caso de botellas con cuello no calibrado, tales como las botellas fabricadas de HDPE (polietileno de alta densidad), por ejemplo, no es posible aplicar tapones de rosca de cierre, como es el caso, en cambio, de las botellas fabricadas de PET. Este problema técnico obliga por tanto a usar cierres fabricados de aluminio, que se sueldan al borde de la botella para garantizar un sellado perfecto. Como se ha dicho, entonces se puede enroscar un tapón de no sellado en el cuello de la botella, dependiendo de las necesidades.In the case of bottles with a non-calibrated neck, such as bottles made of HDPE (high-density polyethylene), for example, it is not possible to apply closure screw caps, as is the case, on the other hand, with bottles made of pet. This technical problem therefore makes it necessary to use closures made of aluminium, which are welded to the edge of the bottle to guarantee a perfect seal. As stated, a non-sealing cap can then be screwed into the neck of the bottle, depending on the needs.
Una desventaja de los opérculos fabricados de aluminio es que se deben esterilizar por separado y a continuación introducirse en la máquina de sellado. Esta es una complicación técnica en el procedimiento de tapado.One disadvantage of caps made of aluminum is that they must be sterilized separately and then inserted into the sealing machine. This is a technical complication in the capping procedure.
Además, los opérculos fabricados de aluminio, un material no biodegradable, implican problemas ecológicos porque muy a menudo el consumidor desecha el opérculo en el medio ambiente después de abrir la botella. Este problema se siente en particular en el caso de las botellas monodosis, con un consumo que está con frecuencia relacionado con el uso en la calle.In addition, caps made of aluminium, a non-biodegradable material, involve ecological problems because the cap is very often disposed of by the consumer in the environment after opening the bottle. This problem is felt in particular in the case of single-dose bottles, with consumption that is often related to use on the street.
Además, es conocido un cierre de acuerdo con el preámbulo de la reivindicación 1 adjunta a partir del documento FR1493504.Furthermore, a closure according to the preamble of appended claim 1 is known from document FR1493504.
Por lo tanto, el problema abordado por la presente invención es la provisión de un cierre para recipientes, en particular botellas con un cuello no calibrado, que supere las desventajas de los cierres conocidos.Therefore, the problem addressed by the present invention is the provision of a closure for containers, in particular bottles with a non-gauge neck, which overcomes the drawbacks of known closures.
Un problema de este tipo se soluciona por un cierre fabricado de material plástico como se define en las reivindicaciones adjuntas, con definiciones que forman parte integrante de la presente descripción.Such a problem is solved by a closure made of plastic material as defined in the appended claims, with definitions forming an integral part of the present description.
Por lo tanto, la presente invención se refiere a un cierre u opérculo fabricado de material plástico esterilizable que se puede aplicar por medio de soldadura al borde del cuello de un recipiente, como se define en una cualquiera de las reivindicaciones de 1 a 8.Therefore, the present invention refers to a closure or lid made of sterilizable plastic material that can be applied by means of welding to the edge of the neck of a container, as defined in any one of claims 1 to 8.
La invención se refiere además a un envase de un producto estéril, preferentemente un producto alimenticio, dietético, farmacéutico, cosmético o de suplemento, como se define en las reivindicaciones 9-10, que comprende un recipiente que tiene un cuello que termina en un borde que rodea una abertura, en el que el cierre u opérculo de la invención está soldado a dicho borde, y en el que dicho cierre u opérculo o partes del mismo no son totalmente extraíbles de dicho envase.The invention also relates to a container for a sterile product, preferably a food, dietetic, pharmaceutical, cosmetic or supplement product, as defined in claims 9-10, comprising a container that has a neck that ends in an edge surrounding an opening, wherein the closure or operculum of the invention is welded to said edge, and wherein said closure or operculum or parts thereof are not fully removable from said container.
La invención se refiere además a un envase que comprende un cierre u opérculo como se define anteriormente, caracterizado por que es resellable, así como al respectivo cierre u opérculo.The invention also refers to a container comprising a closure or lid as defined above, characterized in that it is resealable, as well as the respective closure or lid.

Con referencia a las figuras, el número 1, 101 indica un cierre u opérculo que no forma parte de la invención. El cierre 1, mostrado en la figura 1A, se aplica al borde B de la abertura A de un recipiente C. La abertura A se coloca en el extremo superior del cuello c L del recipiente C. La superficie exterior S del cuello CL, por encima del remate BG, comprende, en el ejemplo mostrado en la figura, una rosca F para enroscar en la misma un tapón de rosca (no mostrado). Sin embargo, se puede omitir la rosca, como en el caso de las botellas monodosis.With reference to the figures, the number 1, 101 indicates a closure or operculum that does not form part of the invention. The closure 1, shown in figure 1A, is applied to the edge B of the opening A of a container C. The opening A is placed at the upper end of the neck c L of the container C. The outer surface S of the neck CL, for above the cap BG, it comprises, in the example shown in the figure, a thread F for screwing a screw cap (not shown) therein. However, the thread can be omitted, as in the case of single-dose bottles.
El cierre 1 tiene una forma sustancialmente discoidal y comprende una porción de borde 2, una porción central 3 parcialmente extraíble y una porción de conexión 4, que comprende una ranura en forma de arco de círculo 5. La ranura en forma de arco de círculo 5 corresponde a una línea de debilitamiento, que tiene un espesor reducido (sección lateral como en la figura 1) con respecto al espesor del cierre 1, y forma una línea de rasgado.The closure 1 has a substantially discoidal shape and comprises an edge portion 2, a partially removable central portion 3 and a connecting portion 4, which comprises an arc-shaped groove 5. The arc-circle groove 5 it corresponds to a line of weakness, which has a reduced thickness (lateral section as in figure 1) with respect to the thickness of the closure 1, and forms a tear line.
La ranura en forma de arco de círculo 5 discurre a lo largo de un arco de círculo de menos de 360°, pero preferentemente mayor de 350°, de modo que la porción de conexión 4 comprende un elemento de vástago 6 dispuesto en la misma circunferencia que la ranura en forma de arco de círculo 5 y configurado para mantener la porción central 3 constantemente conectada a la porción de conexión 4 y/o a la porción de borde 2. Con este fin, el elemento de vástago 6 tiene un espesor de sección lateral que es sustancialmente igual al del cierre 1.The arc-shaped slot 5 runs along an arc of a circle of less than 360°, but preferably greater than 350°, so that the connecting portion 4 comprises a stem element 6 arranged on the same circumference than the circular arc-shaped slot 5 and configured to keep the central portion 3 constantly connected to the connecting portion 4 and/or to the edge portion 2. To this end, the stem element 6 has a lateral section thickness which is substantially the same as closure 1.
Preferentemente, la ranura en forma de arco de círculo 5 tiene una sección en forma de V.Preferably, the arc-shaped slot 5 has a V-shaped section.
En el ejemplo de las figuras 1 y 3, la porción de conexión 4 tiene forma de cono truncado, para conectar la porción de borde 2 y la porción central 3 en diferentes planos, en detalle, el plano en el que se encuentra la porción central 3 es inferior al plano de la porción de borde 2.In the example of figures 1 and 3, the connecting portion 4 has the shape of a truncated cone, to connect the edge portion 2 and the central portion 3 in different planes, in detail, the plane in which the central portion lies 3 is lower than the plane of the edge portion 2.
La porción central 3, dispuesta en el interior de la ranura en forma de arco de círculo 5, tiene forma discoidal y comprende una lengüeta 7 para facilitar el rasgado y la extracción parcial de la porción central 3, que, como se ha dicho, permanecerá sin embargo conectada al cierre 1, y por tanto al recipiente C, por medio del elemento de vástago 6 (véase la figura 3).The central portion 3, arranged inside the arc-shaped groove 5, is discoidal in shape and includes a tab 7 to facilitate tearing and partial removal of the central portion 3, which, as has been said, will remain however connected to the closure 1, and therefore to the container C, by means of the rod element 6 (see figure 3).
Preferentemente, la lengüeta 7 se coloca en el borde 3a de la porción central 3, cerca de la ranura en forma de arco de círculo 5 y en una posición diametralmente opuesta con respecto al elemento de vástago 6, o en un ángulo de ±5° con respecto al mismo a lo largo del borde 3a.Preferably, the tongue 7 is placed on the edge 3a of the central portion 3, close to the arc-shaped groove 5 and in a diametrically opposite position with respect to the stem element 6, or at an angle of ±5° with respect thereto along the edge 3a.
Preferentemente, la lengüeta 7 comprende una porción plana 7a y una porción de unión 7b.Preferably, the tongue 7 comprises a flat portion 7a and a joining portion 7b.
La porción plana 7a es sustancialmente paralela al plano en el que se encuentra la porción central 3, y se encuentra en un plano que es inferior al o coincide con el plano en el que se encuentra la porción de borde 2 del cierre 1. La porción de unión 7b está preferentemente inclinada con un ángulo de menos de 90° con respecto al plano de la porción central 3.The flat portion 7a is substantially parallel to the plane in which the central portion 3 lies, and lies in a plane that is less than or coincides with the plane in which the edge portion 2 of the closure 1 lies. joint 7b is preferably inclined at an angle of less than 90° with respect to the plane of the central portion 3.
Un ejemplo diferente se muestra en la figura 1B, donde la numeración 101, 102, 103, 103a, 104, 105, 106, 107, 107a y 107b identifica elementos correspondientes a los mismos elementos numerados como 1, 2, 3, 3a, 4, 5, 6, 7, 7a y 7b, respectivamente, en la figura 1A.A different example is shown in Figure 1B, where the numbering 101, 102, 103, 103a, 104, 105, 106, 107, 107a, and 107b identifies elements corresponding to the same elements numbered as 1, 2, 3, 3a, 4. , 5, 6, 7, 7a and 7b, respectively, in Figure 1A.
En este ejemplo, el plano en el que se encuentra la porción central 103 es el mismo que el de la porción de borde 102, con lo que la lengüeta 107 sobresale por encima del plano de la porción de borde 102.In this example, the plane in which the central portion 103 lies is the same as that of the edge portion 102, whereby the tongue 107 protrudes above the plane of the edge portion 102.
Las figuras 4 y 5 muestran el cierre de la invención, caracterizado por que es resellable una vez que se ha roto el cierre. El término "resellable" no pretende indicar un cierre hermético, sino el resellado por un número indefinido de veces sin la ayuda de un tapón. Este modo de realización es en particular útil en el caso de bebidas en envases multidosis, tales como leche, zumos de frutas y similares, que se pueden conservar por tanto, por ejemplo, en el frigorífico, incluso durante varios días.Figures 4 and 5 show the closure of the invention, characterized in that it is resealable once the closure has been broken. The term "resealable" is not intended to indicate sealing, but rather resealing an indefinite number of times without the aid of a stopper. This embodiment is particularly useful in the case of beverages in multi-dose containers, such as milk, fruit juices and the like, which can therefore be kept, for example, in the refrigerator, even for several days.
El cierre 201 tiene una forma sustancialmente discoidal y comprende una porción de borde 202 y una porción central 203 parcialmente extraíble.The closure 201 has a substantially discoidal shape and comprises an edge portion 202 and a partially removable central portion 203.
Se coloca una ranura en forma de arco de círculo 205 entre la porción de borde 202 y la porción central 203. An arc-shaped slot 205 is placed between the edge portion 202 and the center portion 203.
La ranura en forma de arco de círculo 205 corresponde a una línea de debilitamiento, que tiene un espesor reducido (sección lateral como en la figura 4) con respecto al espesor del cierre 201, y forma una línea de rasgado.The circular arc-shaped groove 205 corresponds to a line of weakness, which has a reduced thickness (lateral section as in FIG. 4) relative to the thickness of the closure 201, and forms a tear line.
La ranura en forma de arco de círculo 205 discurre a lo largo de un arco de círculo de menos de 360°, pero preferentemente mayor de 350°, para definir un elemento de vástago 206 dispuesto en la misma circunferencia que la ranura en forma de arco de círculo. 205, configurado para mantener la porción central 203 constantemente conectada a la porción de borde 202. Con este fin, el elemento de vástago 206 tiene un espesor de sección lateral que es sustancialmente igual al del cierre 201.The arc-shaped slot 205 runs along an arc of a circle of less than 360°, but preferably greater than 350°, to define a stem element 206 disposed on the same circumference as the arc-shaped slot. of circle. 205, configured to keep central portion 203 constantly connected to edge portion 202. To this end, stem element 206 has a side section thickness that is substantially equal to that of closure 201.
En modos de realización preferentes, la ranura en forma de arco de círculo 205 tiene una sección en forma de V. Como se muestra en la figura 4, el plano en el que se encuentra la porción central 203 es inferior al plano de la porción de borde 202.In preferred embodiments, the circular arc-shaped groove 205 has a V-shaped section. As shown in Fig. 4, the plane in which the central portion 203 lies is lower than the plane of the portion of edge 202.
Con este fin, la porción central 203, dispuesta en el interior de la ranura en forma de arco de círculo 205, comprende una porción rebajada 203a y una porción de conexión 203b con la porción de borde 202, donde dicha porción de conexión 203b tiene una forma sustancialmente cilíndrica y se eleva a partir de la porción rebajada 203a.To this end, the central portion 203, arranged inside the circular arc-shaped groove 205, comprises a recessed portion 203a and a connecting portion 203b with the edge portion 202, said connecting portion 203b having a substantially cylindrical in shape and rises from the lowered portion 203a.
Uno o más salientes anulares 208 configurados para insistir contra la superficie interior del cuello CL del recipiente C están dispuestos en la superficie exterior de la porción de conexión 203b, garantizando por tanto el resellado presurizado del cierre 201 una vez que se ha abierto. Se garantiza el resellado presurizado de este tipo por la interferencia entre los salientes anulares 208 y el cuello CL, debido a la flexibilidad del material del cierre 201, que normalmente es un material plástico flexible.One or more annular projections 208 configured to press against the inner surface of the neck CL of the container C are arranged on the outer surface of the connecting portion 203b, thus ensuring pressurized resealing of the closure 201 once it has been opened. Such a pressurized reseal is ensured by the interference between the annular projections 208 and the neck CL, due to the flexibility of the material of the closure 201, which is normally a flexible plastic material.
La porción rebajada 203a comprende una lengüeta 207 para facilitar el rasgado y la extracción parcial de la porción central 203 que, como se ha dicho, permanecerá sin embargo conectada al cierre 201, y por tanto al recipiente C, por medio del elemento de vástago 206. La lengüeta 207 puede tener forma de anillo, por ejemplo, como se muestra en la figura 5.The lowered portion 203a includes a tab 207 to facilitate tearing and partial removal of the central portion 203 which, as has been said, will nevertheless remain connected to the closure 201, and therefore to the container C, by means of the rod element 206 The tongue 207 can be in the shape of a ring, for example, as shown in Figure 5.
La lengüeta 207 no sobresale más allá de la porción de borde 202 del cierre 201, para permanecer siempre oculta en la cavidad formada entre la porción de borde 202 y la porción rebajada 203a.The tongue 207 does not protrude beyond the edge portion 202 of the closure 201, so as to always remain hidden in the cavity formed between the edge portion 202 and the recessed portion 203a.
En modos de realización preferentes, la lengüeta 207 se coloca en el borde de la porción rebajada 203a, en una posición diametralmente opuesta con respecto al elemento de vástago 206, o en un ángulo de ±5° con respecto al mismo.In preferred embodiments, the tab 207 is placed at the edge of the recessed portion 203a, in a diametrically opposite position with respect to the stem element 206, or at an angle of ±5° with respect thereto.

For example, if the container C is made of HDPE, the closure 1, 101, 201 will also preferably be made of HDPE.
El cierre u opérculo 1, 101, 201 es soldable al borde B del recipiente C por medio de la porción de borde 2, 102, 202. Se podrían usar los sistemas de soldadura normalmente usados para soldar piezas fabricadas de material plástico, sin la ayuda de materiales intermedios, tales como masillas o colas. Por ejemplo, se podría usar una soldadura por ultrasonidos, usando por ejemplo sonotrodos adecuados montados en máquinas taponadoras tradicionales en reemplazo de los cabezales taponadores.The closure or operculum 1, 101, 201 is weldable to the edge B of the container C by means of the edge portion 2, 102, 202. The welding systems normally used to weld parts made of plastic material could be used, without the aid of of intermediate materials, such as mastics or glues. For example, ultrasonic welding could be used, using for example suitable sonotrodes mounted on traditional capping machines instead of capping heads.
El cierre u opérculo 1, 101 se puede esterilizar en el mismo sistema usado para esterilizar el recipiente C.The closure or lid 1, 101 can be sterilized in the same system used to sterilize container C.
Las ventajas de la presente invención son evidentes a partir de lo anterior.The advantages of the present invention are apparent from the above.
El cierre 1, 101, 201 está soldado al borde B del recipiente C, mientras que la porción central 3, 103, 203 está siempre asociada al cierre debido al elemento de vástago 6, 106, 206. Esto permite que el cierre no se deseche en el medio ambiente una vez que se ha abierto el envase.The closure 1, 101, 201 is welded to the edge B of the container C, while the central portion 3, 103, 203 is always associated with the closure due to the stem element 6, 106, 206. This allows the closure not to be discarded. in the environment once the container has been opened.
La posibilidad de fabricar el cierre 1, 101, 201 del mismo material que el recipiente C hace que la producción, esterilización y soldadura del mismo sean en particular económicas y sencillas de producir.The possibility of manufacturing the closure 1, 101, 201 from the same material as the container C makes the production, sterilization and welding of the same particularly economical and simple to produce.
Con respecto a los cierres convencionales fabricados de material plástico (típicamente tapones de rosca), el cierre 1, 101, 201 tiene la ventaja de aplicarse a cuellos no calibrados, tales como los fabricados de HDPE, por ejemplo, haciendo el cierre de la invención similar a los opérculos fabricados de aluminio, de los que se diferencia, sin embargo, debido a un menor coste y una esterilización y soldadura más fáciles.With respect to conventional closures made of plastic material (typically screw caps), closure 1, 101, 201 has the advantage of being applied to non-calibrated necks, such as those made of HDPE, for example, making the closure of the invention similar to caps made of aluminium, from which it differs, however, due to lower cost and easier sterilization and welding.
Además, con respecto a los opérculos fabricados en aluminio, el cierre 1, 101, 201 de la invención se puede abrir más fácilmente debido a la presencia de la lengüeta 7, 207. In addition, with respect to the covers made of aluminum, the closure 1, 101, 201 of the invention can be opened more easily due to the presence of the tab 7, 207.
Si es necesario, el uso del cierre 1, 101 no excluye la aplicación posterior de un tapón de rosca, que se colocará sobre el mismo.If necessary, the use of the closure 1, 101 does not exclude the subsequent application of a screw cap, which will be placed on it.
