Description
Pieza de inserci6n de cierre hermetico para uso con tapones roscados metalicos para recipientes. Hermetic seal insert for use with metal screw caps for containers.
Esta invenci6n se refiere a una pieza de inserci6n de cierre hermetico para uso con tapones para recipientes con cuellos roscados. This invention relates to a sealing insert for use with caps for threaded necks.
Mas especfficamente, la invenci6n se dirige a una pieza de inserci6n de cierre hermetico para uso con tapones roscados metalicos y de aluminio para botellas de vidrio con cuellos roscados. More specifically, the invention is directed to a sealing insert for use with metal and aluminum screw caps for glass bottles with threaded necks.
Los tapones de esta clase comprenden un alojamiento en el que se inserta una pieza de inserci6n de cierre hermetico. The caps of this class comprise a housing in which a sealing insert is inserted.
La pieza de inserci6n de cierre hermetico se disefa para cerrar hermeticamente la boca de la botella cuando se aplica el tap6n al cuello roscado de la misma, y debe garantizar un cierre hermetico incluso cuando la botella contenga un lfquido a presi6n. The sealing insert is designed to tightly close the mouth of the bottle when the cap is applied to the threaded neck of the bottle, and must ensure a tight seal even when the bottle contains a liquid under pressure.
En ese sentido, la pieza de inserci6n de cierre hermetico constituye una interfaz flexible entre la boca del recipiente y la tapa de cierre y es capaz de adaptarse a la rugosidad de la superficie de la boca de la botella. In that sense, the seal insert constitutes a flexible interface between the mouth of the container and the closure lid and is capable of adapting to the roughness of the surface of the mouth of the bottle.
Se conocen varios tipos diferentes de pieza de inserci6n de cierre hermetico para tapones metalicos de botellas. Several different types of airtight insert insert for metal bottle caps are known.
Un inconveniente de las piezas de inserci6n de cierre hermetico de la tecnica anterior es que estas piezas de inserci6n de cierre hermetico frecuentemente sufren dafos durante el proceso de colocaci6n del tap6n de la botella durante el que estan sometidas a intensos esfuerzos mecanicos. A drawback of the prior art seal inserts is that these seal inserts frequently suffer damage during the process of placing the cap of the bottle during which they are subjected to intense mechanical stresses.
Durante la colocaci6n del tap6n, el tap6n metalico es forzado sobre el cuello roscado de la botella y se deforma plasticamente de tal manera que crea un perfil conformado para casar con la rosca del cuello de la botella; si la pieza de inserci6n no esta conformada 6ptimamente,, una gran cantidad de tapones de cierre, durante el proceso de colocaci6n de los tapones, sufren dafos en el extremo de la zona plana del alojamiento en el tap6n de cierre, donde el tap6n se deforma por flexi6n para crear el extremo de comienzo de una parte cilfndrica roscada. During the placement of the cap, the metal cap is forced on the threaded neck of the bottle and plastically deformed in such a way that it creates a profile shaped to match the thread of the bottle neck; if the insert is not optimally shaped, a large number of closure plugs, during the process of placing the plugs, damage is suffered at the end of the flat area of the housing in the closure cap, where the cap deforms by flexion to create the starting end of a threaded cylindrical part.
Ademas, los perfiles de las piezas de inserci6n de la tecnica anterior son mas bien complejos desde el punto de vista geometrico; por tanto, estas piezas de inserci6n son tambien mas bien diffciles de fabricar y, como consecuencia, cierta cantidad de las piezas de inserci6n son defectuosas o no cumplen con las normas de calidad de producci6n. In addition, the profiles of the inserts of the prior art are rather complex geometrically; therefore, these inserts are also rather difficult to manufacture and, as a consequence, a certain amount of the inserts are defective or do not meet production quality standards.
El documento de patente DE 196 14 019 expedido a Alcoa describe una pieza de inserci6n aplicable a un tap6n roscado que comprende una base y una parte que es prominente con respecto a la base. Un inconveniente de esta pieza de inserci6n es que no garantiza un cierre hermetico bajo ciertas condiciones en las que el recipiente esta sometido a altos valores de presi6n y temperatura. El documento DE 198 58 778 describe una pieza de inserci6n de cierre hermetico segun el preambulo de la reivindicaci6n 1. Patent document DE 196 14 019 issued to Alcoa describes an insert applicable to a threaded cap comprising a base and a part that is prominent with respect to the base. A drawback of this insert is that it does not guarantee a tight seal under certain conditions in which the container is subjected to high pressure and temperature values. Document DE 198 58 778 describes a sealing insert according to the preamble of claim 1.
El documento de patente DE 198 58 778 expedido a Alcoa describe un perfeccionamiento de la pieza de inserci6n descrita en el documento de patente DE 196 14 019, que comprende una base y una parte que es prominente con respecto a la base. Patent document DE 198 58 778 issued to Alcoa describes an improvement of the insert described in patent document DE 196 14 019, which comprises a base and a part that is prominent with respect to the base.
La parte prominente comprende unos ensanchamientos en un extremo de la misma y/o uno o mas orificios internos. The prominent part comprises widenings at one end thereof and / or one or more internal holes.
Esta pieza de inserci6n comprende tambien unos rebajos practicados en la periferia de la misma, cuya funci6n es permitir que el aire sea ventilado desde el interior de recipiente si la presi6n en el interior del recipiente resulta excesivamente elevada. This insert also includes recesses made in the periphery thereof, whose function is to allow air to be vented from inside the container if the pressure inside the container is excessively high.
Esta pieza de inserci6n, tambien, por tanto no permite un cierre hermetico 6ptimo en condiciones de una presi6n muy elevada dentro del recipiente; por el contrario, el aire es ventilado desde el interior del recipiente cuando la presi6n en el mismo exceda de unos lfmites predeterminados. This insert, also, therefore, does not allow optimum sealing under conditions of a very high pressure within the container; on the contrary, the air is vented from inside the container when the pressure therein exceeds predetermined limits.
El objeto de esta invenci6n es, por tanto, superar los inconvenientes anteriormente mencionados mediante la provisi6n de una pieza de inserci6n de cierre hermetico para uso con tapones roscados metalicos con los recipientes con cuellos roscados, en particular para botellas, que es de fabricaci6n sencilla y al mismo tiempo resistente a los esfuerzos mecanicos y capaz de garantizar un cierre hermetico incluso en condiciones muy diffciles. The object of this invention is, therefore, to overcome the aforementioned drawbacks by providing a sealing insert for use with metal screw caps with threaded neck containers, in particular for bottles, which is of simple manufacture and at the same time resistant to mechanical stress and able to guarantee a tight seal even in very difficult conditions.
Segun la invenci6n, este objeto se consigue mediante una pieza de inserci6n segun la reivindicaci6n 1. Las caracterfsticas tecnicas adicionales se describen en una o mas de las reivindicaciones adjuntas como apendice a la presente memoria. According to the invention, this object is achieved by an insert according to claim 1. Additional technical features are described in one or more of the appended claims as appendix to the present specification.
Las caracterfsticas tecnicas de la invenci6n, con referencia a los objetos anteriormente indicados, se describen claramente mas adelante en las reivindicaciones y sus ventajas son mas aparentes a partir de la descripci6n detallada que sigue, con referencia a los dibujos adjuntos que ilustran una realizaci6n ejemplar preferida sin caracter limitativo de la invenci6n y en los que: The technical features of the invention, with reference to the objects indicated above, are clearly described later in the claims and their advantages are more apparent from the detailed description that follows, with reference to the accompanying drawings illustrating a preferred exemplary embodiment. without limitation of the invention and in which:
La figura 1 es un corte transversal de una pieza de inserci6n de cierre hermetico segun esta invenci6n aplicada a un tap6n de cierre que no esta aplicado a un recipiente; Fig. 1 is a cross-section of a seal insert according to this invention applied to a closure cap that is not applied to a container;
La figura 2 es una vista en corte transversal de la pieza de inserci6n de cierre hermetico y del tap6n de cierre de la figura 1 roscado al recipiente; Figure 2 is a cross-sectional view of the sealing insert and the closure cap of Figure 1 threaded to the container;
La figura 3 es una vista en corte transversal a escala ampliada de un detalle H de la figura 1. Figure 3 is an enlarged cross-sectional view of a detail H of Figure 1.
Con referencia a los dibujos adjuntos, el numero 1 de la figura 1 designa una pieza de inserci6n de cierre hermetico segun la invenci6n, insertada en un alojamiento cilfndrico 2 de un respectivo tap6n de cierre roscado 3 de un recipiente 4. With reference to the accompanying drawings, the number 1 of Figure 1 designates a seal insert according to the invention, inserted in a cylindrical housing 2 of a respective threaded closure cap 3 of a container 4.
La pieza de inserci6n de cierre hermetico 1 es simetrica con respecto a un eje geometrico y, para mayor sencillez, solamente se ha ilustrado la mitad izquierda en las figuras 1 y 2. The sealing insert 1 is symmetrical with respect to a geometric axis and, for simplicity, only the left half is illustrated in Figures 1 and 2.
El tap6n de cierre 3 comprende un cuerpo metalico 25, preferiblemente de aluminio, que tiene el alojamiento 2 construido en el. The closure cap 3 comprises a metal body 25, preferably of aluminum, having the housing 2 constructed therein.
El alojamiento cilfndrico 2 del tap6n de cierre 3 esta delimitado por una superficie interior superior 6 y por una superficie lateral 7. The cylindrical housing 2 of the closure cap 3 is delimited by an upper inner surface 6 and by a lateral surface 7.
Al tap6n de cierre 3 se hara referencia de ahora en adelante en la presente memoria como tap6n 3. The closure cap 3 will be referred to hereinafter as tap 3.
En las figuras 1 y 2, solamente se ha mostrado, tambien, la mitad del tap6n 3, en una configuraci6n en la que esta aplicado a una botella 4 y en una configuraci6n en la que esta aplicado a la botella, respectivamente In Figures 1 and 2, only half of the cap 3 has also been shown, in a configuration in which it is applied to a bottle 4 and in a configuration in which it is applied to the bottle, respectively
El tap6n 3 es del tipo roscado, y por tanto es adecuado para cerrar botellas 4 del tipo que tiene con un cuello roscado exteriormente. The cap 3 is of the threaded type, and therefore is suitable for closing bottles 4 of the type it has with an externally threaded neck.
La botella 4, de la que solamente otra vez se ha mostrado la mitad - y limitada a la parte donde el tap6n 3 se aplica a ella - se ha ilustrado en las figuras 1 y 2, comprende un cuello roscado exteriormente 5 y una boca 8 disefada para cerrarse hermeticamente mediante el tap6n 3. Bottle 4, of which only half has been shown again - and limited to the part where the cap 3 is applied to it - has been illustrated in Figures 1 and 2, comprises an externally threaded neck 5 and a mouth 8 designed to close tightly by tap 3.
Segun la invenci6n, la pieza de inserci6n 1 comprende una cara frontal interior 9 y una 10 que es prominente con respecto a la cara frontal interior 9 y que esta situada en la periferia 11 de la cara frontal interior 9. According to the invention, the insert 1 comprises an inner front face 9 and a 10 that is prominent with respect to the inner front face 9 and which is located at the periphery 11 of the inner front face 9.
La cara frontal interior 9 comprende una primera superficie 12, disefada para apoyarse en la boca 8 de la botella para cerrar hermeticamente la botella 4, y una segunda superficie 13 enfrente de la primera superficie 12 y disefada para apoyarse en las superficie interior superior 6 del alojamiento cilfndrico 2 del tap6n 3. The inner front face 9 comprises a first surface 12, designed to rest on the mouth 8 of the bottle to tightly close the bottle 4, and a second surface 13 in front of the first surface 12 and designed to rest on the upper inner surface 6 of the cylindrical housing 2 of the plug 3.
La parte prominente 10 sobresale de la primera superficie 12 de la cara frontal interior 9. The prominent part 10 protrudes from the first surface 12 of the inner front face 9.
La cara frontal interior 9 comprende, preferible pero no necesariamente, una parte circular central 15 y una parte periferica anular 14 sustancialmente de mayor espesor que la parte central 15. Preferiblemente, la parte prominente 10 esta situada en la periferia de la parte periferica 14 de la cara frontal interior 9 The inner front face 9 comprises, preferably but not necessarily, a central circular part 15 and an annular peripheral part 14 substantially thicker than the central part 15. Preferably, the prominent part 10 is located on the periphery of the peripheral part 14 of the inner front face 9
La parte prominente 10 comprende una superficie interior 16 y una superficie exterior 17 sustancialmente inclinada hacia fuera con respecto a la primera superficie 12 de la cara frontal interior 9. The prominent part 10 comprises an inner surface 16 and an outer surface 17 substantially inclined outwardly with respect to the first surface 12 of the inner front face 9.
La expresi6n " inclinada hacia fuera con respecto a la primera superficie 12 de la cara frontal interior 9" significa que las tangentes a la superficie interior 16 y a la superficie exterior 17 forman con la primera superficie 12 de la cara frontal interior 9 un angulo sustancialmente agudo. The expression "inclined outwardly with respect to the first surface 12 of the inner front face 9" means that the tangents to the inner surface 16 and the outer surface 17 form with the first surface 12 of the inner front face 9 a substantially acute angle .
Con referencia a la figura 1, la superficie interior 16 esta proximal a la cara frontal interior 9, mientras que la superficie exterior 17 esta distal de la cara frontal interior 9. With reference to Figure 1, the inner surface 16 is proximal to the inner front face 9, while the outer surface 17 is distal to the inner front face 9.
La parte prominente 10 comprende ademas una superficie convexa 19 disefada para conectar la superficie interior 16 y la superficie exterior 17. The prominent part 10 further comprises a convex surface 19 designed to connect the inner surface 16 and the outer surface 17.
Preferiblemente, como se ha ilustrado en la figura 3, la superficie convexa 19 comprende partes de arco. Preferably, as illustrated in Figure 3, the convex surface 19 comprises arc portions.
La superficie interior 16 y la superficie exterior 17 de la parte prominente 10 estan inclinadas con respecto a la primera superficie 12 de la cara frontal 9 de tal manera que, como mfnimo, una parte de la parte prominente 10 se estrecha progresivamente en el sentido de alejarse de la cara frontal interior 9, es decir, en una direcci6n sustancialmente inclinada separandose de la cara frontal interior 9 hacia fuera y hacia abajo, con referencia la figura The inner surface 16 and the outer surface 17 of the prominent part 10 are inclined with respect to the first surface 12 of the front face 9 such that, at a minimum, a part of the prominent part 10 progressively narrows in the direction of moving away from the inner front face 9, that is, in a substantially inclined direction separating from the inner front face 9 outward and downward, with reference to the figure
3. 3.
Dicho de otro modo, la superficie interior 16 y la superficie exterior 17 estan conformadas de tal manera que la totalidad de la parte prominente 10 se estrecha progresivamente alejandose de la cara frontal interior 9; garantizando de ese modo ventajosamente un cierre hermetico 6ptimo sobre el cuello de la botella. In other words, the inner surface 16 and the outer surface 17 are shaped in such a way that the whole of the prominent part 10 gradually narrows away from the inner front face 9; thereby advantageously guaranteeing an optimum seal on the neck of the bottle.
A la luz de lo anteriormente expuesto, hay que hacer notar que la parte prominente 10, que se extiende en el sentido de alejarse de la cara frontal interior 9, no tiene ninguna parte ensanchada o estrecha, (es decir, su estrechamiento progresivo es tal que su secci6n transversal disminuye constantemente con la extensi6n en el sentido de separarse de la cara frontal interior). In the light of the foregoing, it should be noted that the prominent part 10, which extends in the direction of moving away from the inner front face 9, has no widened or narrowed part, (i.e., its progressive narrowing is such that its cross section decreases constantly with the extension in the sense of separating from the inner front face).
Hay que hacer notar que, sorprendentemente, la forma de la pieza de inserci6n es especialmente adecuada para permitir que el tap6n garantice un cierre hermetico incluso cuando la presi6n dentro del recipiente sea muy elevada. It should be noted that, surprisingly, the shape of the insert is especially suitable to allow the cap to guarantee a tight seal even when the pressure inside the container is very high.
El hecho de que la totalidad de la pieza de inserci6n se estreche progresivamente en el sentido de alejarse de la cara frontal interior permite que la pieza de inserci6n experimente una deformaci6n cuando se prense a su posici6n, garantizando de ese modo un cierre hermetico 6ptimo. The fact that the entire insert inserts progressively narrow in the direction of moving away from the inner front face allows the insert to undergo deformation when pressed into position, thereby guaranteeing an optimal seal.
Hay que hacer notar tambien que la forma especial de la parte prominente 10, con una superficie interior 16, una superficie exterior 17 y una superficie convexa 19 de uni6n, ademas de proveer un cierre hermetico extremadamente eficaz, hace que el proceso de fabricaci6n de la pieza de inserci6n sea rapido y sencillo ( puesto que la pieza de inserci6n sf requiere cualesquiera partes socavadas y/o caracterfsticas post-procesamiento tales como orificios). It should also be noted that the special shape of the prominent part 10, with an inner surface 16, an outer surface 17 and a convex joining surface 19, in addition to providing an extremely effective seal, makes the manufacturing process of the insertion piece is fast and simple (since the insertion piece only requires any undercut parts and / or post-processing characteristics such as holes).
Preferiblemente, la superficie interior 16 y la superficie exterior 17 forman un angulo agudo a. Preferably, the inner surface 16 and the outer surface 17 form an acute angle a.
Con preferencia, el angulo a es menor de 40°. Preferably, the angle a is less than 40 °.
Ademas, la superficie interior 16 esta inclinada preferiblemente con respecto a la primera superficie 12 de la cara frontal interior 9 formando un angulo � sustancialmente menor de 35°. In addition, the inner surface 16 is preferably inclined with respect to the first surface 12 of the inner front face 9 forming an angle � substantially less than 35 °.
La superficie exterior 17 comprende un alargamiento 24 que es sustancialmente perpendicular a la primera superficie 12 de la cara frontal interior 9 para su uni6n a la segunda superficie 13 de la cara frontal interior 9. The outer surface 17 comprises an elongation 24 that is substantially perpendicular to the first surface 12 of the inner front face 9 for attachment to the second surface 13 of the inner front face 9.
La superficie exterior 17 y la superficie interior 16 son sustancialmente c6ncavas con respecto a una direcci6n radial en el sentido de separarse de la cara frontal interior. The outer surface 17 and the inner surface 16 are substantially concave with respect to a radial direction in the direction of separating from the inner front face.
La pieza de inserci6n 1 de cierre hermetico se construye preferiblemente de una sola pieza. The sealing insert 1 is preferably constructed of a single piece.
Preferiblemente la pieza de inserci6n 1 de cierre hermetico se fabrica de un polfmero, elegido del grupo que incluye polipropileno (en adelante PP). polietileno (en adelante PE) y compuestos de los mismos, o bien de cloruro de polivinilo (en adelante PVC). Preferably, the sealing insert 1 is made of a polymer, chosen from the group that includes polypropylene (hereinafter PP). polyethylene (hereinafter PE) and compounds thereof, or polyvinyl chloride (hereinafter PVC).
La pieza de inserci6n 1 de cierre hermetico se construye preferiblemente con un troquel de punzonar que comprende una cavidad que esta conformada para casar con la pieza de inserci6n. The sealing part 1 is preferably constructed with a punching die comprising a cavity that is shaped to match the insert.
Ventajosamente,, el perfil de la pieza de inserci6n 1 de cierre hermetico se puede hacer muy facilmente a escala industrial, puesto que tiene unas partes rectas y arqueadas y, en terminos geometricos, es relativamente sencillo de construir. Advantageously, the profile of the sealing insert 1 can be made very easily on an industrial scale, since it has straight and arched parts and, in geometric terms, is relatively simple to construct.
Una comparaci6n de la figura 1, donde el tap6n 3 no se ha aplicado al cuello 5 de la botella 4, con la figura 2, donde el tap6n 3 se ha aplicado al cuello 5 de la botella 4, muestra claramente la deformaci6n que experimenta la pieza de inserci6n 1 de cierre hermetico cuando el tap6n 3 se aplica al cuello 5 de la botella 4 para cerrar la boca 8 de esta ultima. A comparison of Figure 1, where the cap 3 has not been applied to the neck 5 of the bottle 4, with Figure 2, where the cap 3 has been applied to the neck 5 of the bottle 4, clearly shows the deformation experienced by the insert 1 for sealing when the cap 3 is applied to the neck 5 of the bottle 4 to close the mouth 8 of the latter.
De hecho, durante el proceso de colocaci6n del tap6n, el tap6n 3 llega a deformarse de tal manera que el perfil del cuerpo metalico 25 llega a conformarse para sustancialmente casar con la forma de la rosca del cuello 5 de la botella 4, y la parte prominente 10 experimenta una deformaci6n como resultado de la acci6n de compresi6n aplicada a el por la superficie exterior 21 del cuello 5 de la botella 4 y por la superficie lateral 7 del alojamiento cilfndrico 2 del tap6n 3. In fact, during the process of placing the cap, the cap 3 becomes deformed in such a way that the profile of the metal body 25 becomes shaped to substantially match the shape of the neck thread 5 of the bottle 4, and the part prominent 10 undergoes a deformation as a result of the compression action applied to it by the outer surface 21 of the neck 5 of the bottle 4 and by the lateral surface 7 of the cylindrical housing 2 of the cap 3.
De ese modo, como se muestra en la figura 2, cuando el tap6n 3 se aplica al cuello 5 de la botella 4, la superficie exterior 17 de la parte prominente 10 se adhiere a la superficie lateral 7 del alojamiento cilfndrico 2, mientras que la superficie interior de la parte prominente 10 se adhiere a la superficie exterior 21 del cuello 5 de la botella 4. Thus, as shown in Figure 2, when the cap 3 is applied to the neck 5 of the bottle 4, the outer surface 17 of the prominent part 10 adheres to the side surface 7 of the cylindrical housing 2, while the inner surface of the prominent part 10 adheres to the outer surface 21 of the neck 5 of the bottle 4.
La parte prominente 10 hace posible reducir las deformaciones mecanicas sobre el tap6n 3 y sobre la botella 4 durante donde el proceso de colocaci6n del tap6n; cuando el tap6n 3 se aplica a la botella, la parte prominente 10 se deforma elasticamente y de ese modo hace posible reducir la deformaci6n del tap6n 3 en la zona del extremo de la superficie plana de la superficie interior 6 de la cara frontal interior 9 del alojamiento cilfndrico 2. The prominent part 10 makes it possible to reduce the mechanical deformations on the cap 3 and on the bottle 4 during which the process of placing the cap; when the cap 3 is applied to the bottle, the prominent part 10 is elastically deformed and thereby makes it possible to reduce the deformation of the cap 3 in the area of the end of the flat surface of the inner surface 6 of the inner front face 9 of the cylindrical housing 2.
La parte prominente 10, cuando el tap6n 3 se aplica a la botella 4, forma una parte de extremo ensanchada 22 que permite que la deformaci6n del tap6n 3 se reduzca adicionalmente durante el proceso de colocaci6n del tap6n. The prominent part 10, when the cap 3 is applied to the bottle 4, forms an enlarged end portion 22 which allows the deformation of the cap 3 to be further reduced during the process of placing the cap.
La parte de extremo ensanchada 22 actua tambien como un elemento amortiguador interpuesto entre el tap6n 3 y la botella 4. The widened end portion 22 also acts as a damping element interposed between the cap 3 and the bottle 4.
Ventajosamente, la parte prominente 10 impide que se dafe la pieza de inserci6n 1 de cierre hermetico en la zona de extremo plana de la suficiente interior superior 6 de la cara frontal interior del alojamiento cilfndrico 2 del tap6n 3 cuando el tap6n 3 se aplica a la botella 4. Advantageously, the prominent part 10 prevents damage of the sealing insert 1 in the flat end area of the sufficient upper inner 6 of the inner front face of the cylindrical housing 2 of the cap 3 when the cap 3 is applied to the bottle 4.
Ademas, ventajosamente, una parte de la superficie interior 16 de la parte prominente 12 se adhiere a la superficie superior 23 de la boca 8 de la botella 4; esto garantiza un cierre hermetico de la boca 8 de la botella 4 incluso en presencia de un lfquido a presi6n. In addition, advantageously, a part of the inner surface 16 of the prominent part 12 adheres to the upper surface 23 of the mouth 8 of the bottle 4; this guarantees a tight seal of the mouth 8 of the bottle 4 even in the presence of a pressurized liquid.
Una ventaja de esta invenci6n es que hace que se disponga de una pieza de inserci6n de cierre hermetico para uso con tapones roscados metalicos de recipientes, en particular botellas, que es de fabricaci6n sencilla y al mismo tiempo resistente a los esfuerzos mecanicos, especialmente durante el proceso de colocaci6n del tap6n. An advantage of this invention is that it makes available a sealing insert for use with metal screw caps of containers, in particular bottles, which is of simple manufacture and at the same time resistant to mechanical stress, especially during the plug placement process.
Merced a su forma especial, la pieza de inserci6n de cierre hermetico garantiza un cierre hermetico de la botella incluso en la presencia de un lfquido a presi6n (o incluso en presencia de esfuerzos mecanicos). Thanks to its special shape, the hermetic seal insert guarantees a tight seal of the bottle even in the presence of a pressurized liquid (or even in the presence of mechanical stresses).
Hay que hacer notar r que, preferiblemente, la parte prominente de la pieza de inserci6n no tiene rebajos, agujeros o partes ensanchadas, de acuerdo con este aspecto, la parte prominente es una parte no interrumpida de material, es decir, una parte sin cavidades y/o agujeros practicados en ella. It should be noted that, preferably, the prominent part of the insert does not have recesses, holes or widened parts, according to this aspect, the prominent part is an uninterrupted part of material, that is, a part without cavities and / or holes made in it.
Ello garantiza una deformaci6n 6ptima y permite que el cierre permanezca hermeticamente cerrado de un modo eficaz incluso en condiciones muy diffciles. This guarantees optimum deformation and allows the closure to remain tightly closed in an efficient manner even under very difficult conditions.
Hay que hacer notar tambien que la parte prominente 10 se extiende anularmente alrededor de la cara frontal interior 9 de un modo ininterrumpido, es decir, sin ninguna interrupci6n en ella ( es decir, la parte prominente 10 circunda a todo el borde periferico de la cara frontal interior 9); esto garantiza un cierre perfectamente hermetico en cualquier zona del recipiente. It should also be noted that the prominent part 10 extends annularly around the inner front face 9 in an uninterrupted manner, that is, without any interruption therein (that is, the prominent part 10 surrounds the entire peripheral edge of the face inner front 9); This guarantees a perfectly tight closure in any area of the container.
De hecho, hay que hacer notar que esta soluci6n garantiza un cierre hermetico incluso en condiciones muy diffciles todo alrededor del borde del cuello de la botella ( a diferencia de algunas soluciones de la tecnica anterior, tales como por ejemplo la descrita en el documento de 198 58 778, que contemplaba la ventilaci6n del aire cuando la presi6n interior del recipiente excediese de ciertos lfmites). In fact, it should be noted that this solution guarantees a tight seal even in very difficult conditions all around the edge of the bottleneck (unlike some prior art solutions, such as for example the one described in document 198 58 778, which contemplated the ventilation of the air when the internal pressure of the vessel exceeded certain limits).
El invento anteriormente descrito es susceptible de aplicaci6n industrial y se podrfa modificar y adaptar de varias maneras sin apartarse de ese modo del alcance del concepto de la invenci6n segun se ha reivindicado. The invention described above is susceptible of industrial application and could be modified and adapted in various ways without thereby departing from the scope of the concept of the invention as claimed.
