Abstract

The invention comprises a one-piece body (1) in the form of a domed component, of any external geometrical configuration, which converges towards the opening (2) thereof, the inner wall of which has a profile or a generatrix that coincides with that of the bottle neck with which it has to fit tightly, a protuberance (12) of hemispherical configuration emerging downwards from the bottom of the base thereof, which projection is designed, in turn, to penetrate tightly inside the bottle neck, this coupling being facilitated by the existence of a bevel (6) at the mouth of the stopper. This results in a stopper that, despite being made from silicone, can easily be coupled to the bottle and is capable of withstanding the pressure inside the bottle without accidentally becoming detached therefrom.

TAPÓN DE SILICONA PARA BOTELLAS  SILICONE BOTTLE PLUG
DE CAVA Y SIMILARES  CAVA AND SIMILAR
D E S C R I P C I Ó N D E S C R I P C I Ó N
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención se refiere a un tapón de silicona, que ha sido especialmente concebido para botellas de cava y similares, como por ejemplo de champagne. The present invention relates to a silicone stopper, which has been specially designed for bottles of champagne and the like, such as champagne.
El objeto de la invención es conseguir una óptima estanqueidad entre el tapón y el gollete de la botella que mejore las condiciones de envasado de la bebida. The object of the invention is to achieve an optimum seal between the cap and the neck of the bottle that improves the packaging conditions of the beverage.
ANTECEDENTES DE LA INVENCIÓN Como es sabido las botellas de cava se cierran desde tiempo inmemorial mediante un tapón cilindrico, de corcho natural o de aglomerado de corcho, cuyo diámetro es considerablemente mayor que el diámetro interno del gollete de la botella de manera que en la operación de taponado se provoca una fuerte contracción radial de la porción de tapón alojada dentro de la botella, con la doble finalidad de, por un lado estabilizar en cierta medida el tapón con respecto a la botella, y por otro reducir en lo posible la porosidad del corcho, para evitar pérdidas a través del mismo. BACKGROUND OF THE INVENTION As it is known, the cava bottles are closed from time immemorial by means of a cylindrical, natural cork or cork agglomerate cap, whose diameter is considerably larger than the internal diameter of the bottle neck so that in operation of capping causes a strong radial contraction of the cap portion housed inside the bottle, with the dual purpose of, on the one hand stabilizing the cap to a certain extent with respect to the bottle, and on the other reducing as far as possible the porosity of the cork, to avoid losses through it.
Mas reciente se está produciendo en la industria del taponado una evolución hacia la utilización de otras materias primas, concretamente silicona. En este sentido cabe citar la Patente de Invención US 2011108511 que divulga un tapón de silicona con unos nervios perimetrales, de diámetro decreciente en sentido descendente, que facilita tanto el sellado como una retirada fácil del tapón, para lo que el tapón cuenta con una expansión en el exterior a la botella y que sirve de tope limite de penetración en el seno de la misma. More recent, there is an evolution in the capping industry towards the use of other raw materials, specifically silicone. In this regard, it is worth mentioning the US Invention Patent 2011108511 which discloses a silicone plug with perimeter ribs, of decreasing diameter in the descending direction, which facilitates both sealing and easy removal of the cap, for which the cap has an expansion on the outside of the bottle and which serves as a limit of penetration within it.
Existen también tapones que reproducen fielmente la configuración cilindrica de un tapón de corcho convencional, pero en este caso obtenidos a base de silicona, que en el mejor de los casos resultan apropiados para el cierre de botellas de vino, así como de otros productos que no alcanzan una presión considerable en el interior de la botella. There are also stoppers that faithfully reproduce the cylindrical configuration of a conventional cork stopper, but in this case obtained based on silicone, which in the best case are suitable for closing wine bottles, as well as other products that do not they reach considerable pressure inside the bottle.
Existen también tapones como el que muestra la Patente de In- vención US 20100050576 de naturaleza híbrida, consistentes en un anillo de silicona al que está convenientemente fijada una chapa de retención metálica, concretamente de aluminio, tapón que tampoco resulta idóneo, ni mucho menos, para el cierre de botellas de cava. También para cierre de botellas, en particular de botellas de vino, se conoce la Patente de Invención DE 19731620, en la que se utiliza silicona sin vulcanizar, que aumenta de diámetro una vez colocado el tapón y ser vulcanizada con un catalizador de peróxido, lo que supone un complejo proceso de fabricación del tapón. There are also plugs such as the one shown in the US Patent No. 20100050576 of a hybrid nature, consisting of a silicone ring to which a metal retaining plate, namely aluminum, is conveniently attached, a plug that is not suitable, much less, for closing champagne bottles. Also for the closure of bottles, in particular of wine bottles, the Invention Patent DE 19731620 is known, in which non-vulcanized silicone is used, which increases in diameter once the stopper is placed and is vulcanized with a peroxide catalyst, which involves a complex process of manufacturing the plug.
El documento CN 20102108471U divulga también un tapón de silicona para botellas de vino, similar al de la Patente de Invención US 2011108511, que incorpora además un tirador en forma de media luna y articulado, tapón que tampoco resulta idóneo, ni mucho menos, para botellas de cava. DESCRIPCIÓN DE LA INVENCIÓN Document CN 20102108471U also discloses a silicone stopper for wine bottles, similar to that of US Patent 2011108511, which also incorporates a half-moon and articulated handle, a cap that is not suitable, much less, for bottles of cava DESCRIPTION OF THE INVENTION
La invención propone un tapón de silicona capaz de ofrecer unas óptimas prestaciones como elemento de cierre para botellas de cava. The invention proposes a silicone stopper capable of offering optimum performance as a closure element for cava bottles.
Para ello, y de forma mas concreta, dicho tapón está constituido mediante un cuerpo monopieza, a modo de cazoleta, de configuración general externa tronco-cónica, convergente hacia su embocadura, y con una configuración interna que copia fielmente el gollete específico y particular de una botella de cava, al que ha de adaptarse perfectamente. For this, and more specifically, said cap is constituted by a single piece body, as a bowl, with a general trunk-conical external configuration, convergent towards its mouth, and with an internal configuration that faithfully copies the specific and particular neck of a bottle of cava, which has to adapt perfectly.
Del centro de la base del cuerpo del tapón emerge axial e infe- riormente una protuberancia de configuración semiesférica peraltada, destinada a alojarse ajustadamente en el interior del gollete o cuello de la botella. A protruding semi-spherical configuration emerges axially from the center of the base of the cap body, and is intended to fit tightly inside the neck or neck of the bottle.
De acuerdo con otra de las características de la invención, el tapón propiamente dicho está ligeramente infradimensionado con respecto al gollete de la botella, en orden a que su acople y fijación no solo se produzca por el efecto machihembrado entre ambos elementos, sino también por una deformación elástica y radial del tapón, que por recuperación asimismo elástica, incrementa la presión del cierre. According to another of the features of the invention, the cap itself is slightly under-sized with respect to the neck of the bottle, in order that its coupling and fixation not only occurs due to the tongue and groove effect between both elements, but also by a elastic and radial deformation of the cap, which by elastic recovery also increases the pressure of the closure.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el tapón que la invención propone está constituido mediante un cuerpo monopie- za (1) que configura a modo de una cazoleta exteriormente tronco-cónica, convergente hacia su embocadura (2), de pared lateral con una generatriz (3) ligeramente curvo convexa, que se une a través de una arista perimetral redondeada (4) a su base (5), que también es curvo-convexa. El cuerpo (1) puede ser de cualquier configuración externa geométricamente conveniente. In view of the aforementioned figures, it can be seen how the cap proposed by the invention is constituted by a mono-piece body (1) that configures as an externally trunk-conical bowl, convergent towards its mouth (2), side wall with a generatrix (3) slightly curved convex, which joins through a rounded perimeter edge (4) to its base (5), which is also curved-convex. The body (1) can be of any geometrically convenient external configuration.
El interior del citado cuerpo (1), es decir el interior de la cazóle- ta, tiende a la configuración cilindrica, pero con un bisel (6) a nivel de su embocadura (2) para facilitar su acoplamiento a la botella, con una garganta perimetral (7) formal y posicionalmente acorde con el clásico nervio perimetral (8) con el que cuentan las botellas de cava (9), y con una expansión perimetral redondeada (10) próxima a su base, a su vez formal y posicionalmente acorde con el también clásico reborde semi-toroidal (11) del gollete de la botella (9), de manera que entre la superficie lateral y perimetral interna del tapón y la superficie lateral y perimetral externa del gollete de la botella se produce un perfecto ajuste. The interior of the aforementioned body (1), that is to say the interior of the hunt ta, tends to the cylindrical configuration, but with a bevel (6) at the level of its mouth (2) to facilitate its coupling to the bottle, with a perimeter throat (7) formally and positionally in line with the classic perimeter nerve (8) with which the bottles of cava (9) count, and with a rounded perimeter expansion (10) close to its base, in turn formally and positionally in line with the also classic semi-toroidal flange (11) of the bottle neck (11) 9), so that a perfect fit occurs between the inner side and perimeter surface of the cap and the outer side and perimeter surface of the bottle neck.
La estructura del tapón se completa con una acusada protuberancia (12) que emerge interiormente de la zona central de la base de la cazoleta, de configuración semiesférica peraltada y destinada a alojarse a su vez ajustadamente, en posición de cierre en el interior del gollete de la botella. The structure of the cap is completed with a pronounced protuberance (12) that emerges internally from the central area of the base of the bowl, with a semi-spherical configuration and is intended to stay tightly, in a closed position inside the neck of the the bottle
Esta protuberancia (12) que penetra fácilmente en el seno de la botella, por la configuración semiesférica de su extremidad libre, presenta un diámetro acusadamente sobredimensionado con respecto al diámetro interior de la botella (9), a la vez que la pared lateral del cuerpo presenta su interior a su vez ligeramente infradimensionado con respecto al gollete de la botella, para conseguir que la tendencia a la expansión radial de la protuberancia (12) por un lado, y la tendencia a la contracción radial de la pared lateral del tapón por otro, generen una óptima posición de cierre que potencia la efectividad del tapón. This protuberance (12) that easily penetrates the bosom of the bottle, due to the hemispherical configuration of its free end, has a markedly oversized diameter with respect to the inner diameter of the bottle (9), as well as the side wall of the body It presents its interior, in turn, slightly under-sized with respect to the neck of the bottle, to achieve that the tendency to radial expansion of the protuberance (12) on the one hand, and the tendency to radial contraction of the side wall of the cap on the other , generate an optimal closing position that enhances the effectiveness of the cap.
