Abstract

The invention relates to a seal for crown-type caps used to seal bottles and other containers housing pressurised liquids (drinks and, in particular, cava, champagne, sparkling wine, etc.), which guarantees that the cap-fitted bottle is sealed. The seal takes the form of a planar disk provided with partial or full rings and positioned on the upper edge of the bottle. The shape of the seal enables same to be maintained in position in a uniform, controlled manner, applying pressure against the edge of the bottle by means of an outer ring and uniformly controlling the radial surface of the stopper by means of a second inner ring. The seal significantly reduces production costs and the associated environmental impact.

JUNTA DE TAPÓN CORONA PARA SELLADO ESTANCO Y OBTURADO DE BOTELLAS Y OTROS RECIPIENTES A PRESIÓNCROWN PLUG SEAL FOR SEALED AND SEALED SEALING OF BOTTLES AND OTHER PRESSURE CONTAINERS
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
El objeto de Ia presente invención es una junta para tapones del tipo corona para el sellado de botellas y otros recipientes que contienen líquidos a presión (bebidas, en particular, cavas, champán, vinos espumosos, etc), Ia cual garantiza Ia estanqueidad de Ia botella a Ia cual se aplica tapas, junta que con su forma de disco plano dotado de anillos parciales o completos está situada sobre el mismo borde superior de Ia botella; y que gracias a su geometría se mantiene en su posición de manera uniforme, controlada y presionando sobre el borde de Ia botella mediante un anillo exterior, y controlando Ia superficie radial del obturador de manera uniforme mediante un segundo anillo interior; y que gracias a Ia tecnología y materiales empleados en su elaboración reduce sensiblemente los costes de su elaboración y el impacto ambiental.The object of the present invention is a seal for crown type caps for sealing bottles and other containers containing pressurized liquids (beverages, in particular, cavas, champagne, sparkling wines, etc.), which guarantees the tightness of the bottle to which caps are applied, gasket that with its flat disk shape provided with partial or complete rings is located on the same upper edge of the bottle; and that thanks to its geometry it is maintained in its position in a uniform manner, controlled and pressing on the edge of the bottle by an outer ring, and controlling the radial surface of the shutter uniformly by a second inner ring; and that thanks to the technology and materials used in its elaboration it significantly reduces the costs of its elaboration and the environmental impact.
ESTADO DE LA TÉCNICASTATE OF THE TECHNIQUE
En general, en Ia actualidad se puede observar que existen diversas soluciones patentadas para el sellado de botellas y recipientes de líquidos, con terminación adecuada al uso de los tapones corona. Dentro de éstas cabe distinguir por un lado las que presentan juntas que se extienden hacia fuera del perímetro exterior de Ia terminación de Ia botella, o una segunda clase, las que se extienden hacia adentro de Ia propia botella. Por su diferencia respecto al objeto de Ia invención no tomaremos en cuanta Ia primera clase, cuyos costes de elaboración son significativamente más elevados.In general, at present it can be seen that there are several patented solutions for sealing bottles and liquid containers, with termination suitable for the use of crown caps. Within these, it is possible to distinguish on the one hand those that present joints that extend outward from the outer perimeter of the completion of the bottle, or a second class, those that extend into the bottle itself. Due to its difference with respect to the object of the invention, we will not take into account the first class, whose manufacturing costs are significantly higher.
Actualmente, Ia solución más implantada es aquella en Ia que presenta juntas para tapones corona en forma de discos, situadas sobre el extremo superior de Ia boca de Ia botella y con un diámetro exterior inferior al perímetro exterior de Ia boca; otras, las más cercanas al objeto de Ia presente invención, se encuentran en forma de discos, aunque éstos sean en forma de revestimiento interior del tapón.Currently, the most implanted solution is that in which it presents seals for crown caps in the form of discs, located on the upper end of the mouth of the bottle and with an outer diameter smaller than the outer perimeter of the mouth; others, those closest to the object of the present invention, are in the form of discs, although these are in the form of an inner lining of the cap.
Dentro de las juntas que garantizan alta estanqueidad en el sellado de los recipientes cabe señalar el documento GB1134178 que enseña una junta constituida por dos componentes: un recubrimiento del tapón formado por un plástico no espumado y un segundo componente en forma de anillo, confeccionado de un material espumado..Within the joints that guarantee high tightness in the sealing of the containers, it is worth noting document GB1134178 which teaches a joint consisting of two components: a cap covering formed by a non-foamed plastic and a second ring-shaped component, made of a foamed material ..
El documento GB884126 (N0 5) propone una junta de sellado con un material elástico o deformable, una goma, con dos recubrimientos del tapón: uno noGB884126 (N 0 5) proposes a sealing gasket with an elastic or deformable material, a rubber, with two coverings of the cap: one not
HOJA DE SUSTITUCIÓN (REGLA 26) adherente confeccionado con resinas fenólico-epóxidas y otro adherente de una laca vinílica. Las diferencias son las mismas que en Ia anterior.SUBSTITUTE SHEET (RULE 26) adherent made with phenolic-epoxy resins and another adherent of a vinyl lacquer. The differences are the same as in the previous one.
Sin embargo Ia elaboración de estas juntas bi-componentes no es sencilla al involucrar dos componentes diferentes.However, the elaboration of these bi-component joints is not simple by involving two different components.
Dentro de las juntas de un solo cuerpo, el documento GB963074 propone una junta blanda basada en cloruro de polivinilo que ajusta sobre el tapón. Las más modernas, de uso muy extendido actualmente, son éstas que cuentan con un solo anillo. Sin embargo, aunque el coste de elaboración respecto a las de b¡- componentes es inferior por Ia sencillez de su elaboración, adolecen de una serie de desventajas. Entre éstas, se señalan un coste de producción aún relativamente elevado y un sellado deficiente, que no garantiza totalmente Ia estanqueidad.Within the single-body gaskets, GB963074 proposes a soft gasket based on polyvinyl chloride that fits over the cap. The most modern, widely used today, are those that have a single ring. However, although the cost of processing with respect to those of b-components is lower due to the simplicity of its elaboration, they suffer from a series of disadvantages. Among these, a still relatively high production cost and poor sealing are indicated, which does not fully guarantee the tightness.
Sin embargo, dentro de estos sistemas para las juntas el elemento que garantiza mínimamente tanto Ia obturación, o sea Ia estanqueidad, como el control del obturado es un disco troquelado generalmente de polietileno o polipropileno espumado que hace las dos funciones mencionadas, pero tiene un costo aún relativamente elevado por tres motivos:However, within these joint systems, the element that minimally guarantees both the sealing, that is the sealing, and the sealing control is a die-cut disk generally made of polyethylene or foamed polypropylene that performs the two functions mentioned, but has a cost still relatively high for three reasons:
1o La placa ya ha sufrido un proceso de fabricación previa para conseguir Ia cualidad deseada a partir de Ia materia prima. 2o Es un disco troquelado que genera desperdicios1 o The plate has already undergone a previous manufacturing process to achieve the desired quality from the raw material. 2 o It is a die cut disc that generates waste
3o Tanto Ia elaboración como el troquelado constituyen un proceso de fabricación laborioso.3 o Both processing and die cutting constitute a laborious manufacturing process.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La invención consiste en una junta de tapón corona que gracias a Ia geometría de su forma novedosa de disco, garantiza una estanqueidad superior y un mejor control eficaz del obturado que las de Ia técnica anterior. La junta de Ia invención está integrada en un solo cuerpo en forma de disco elástico que comprende dos anillos concéntricos, totales continuos o interrumpidos parcialmente, y en Ia que se puede distinguir los siguientes elementos: un primer anillo exterior con su cara superior hendida (destinada a ser Ia superficie de contacto con Ia superficie del cuello de Ia botella), un segundo anillo interior para el contacto con el obturador y una superficie interior plana.The invention consists of a crown plug gasket that, thanks to the geometry of its novel disk shape, guarantees superior sealing and better effective sealing control than those of the prior art. The gasket of the invention is integrated in a single body in the form of an elastic disk comprising two concentric rings, total continuous or partially interrupted, and in which the following elements can be distinguished: a first outer ring with its split upper face (intended to be the contact surface with the surface of the neck of the bottle), a second inner ring for contact with the shutter and a flat inner surface.
El primer anillo exterior es lógicamente el de mayor diámetro, pero también el de mayor anchura transversal y altura, teniendo una sección transversal compuesta por dos triángulos separados por una hendidura, aunque dicha forma triangular puede adoptar cualquier otra forma geométrica adecuada a su función, tal como trapecial, elíptica, semicircular o similares. Dicho primer anillo exterior está destinado a servir de superficie de contacto con Ia superficie del borde superior de Ia botella o recipiente a fin de lograr Ia estanqueidad por compresión comoThe first outer ring is logically the one with the greatest diameter, but also the one with the greatest transverse width and height, having a cross-section consisting of two triangles separated by a slit, although said triangular shape can adopt any other geometric shape suitable to its function, such as trapecial, elliptical, semicircular or similar. Said first outer ring is intended to serve as a contact surface with the surface of the upper edge of the bottle or container in order to achieve compression tightness as

Un rasgo característico de dicha cara superior del primer anillo exterior es estar provista de una hendidura superior central que en profundidad llega aproximadamente hasta Ia mitad de Ia altura de dicho primer anillo exterior Dicha hendidura está destinada a facilitar, durante Ia colocación del tapón corona, Ia expansión de dicho anillo exterior por aplastamiento y el asentamiento de dicho anillo exterior sobre Ia mayor parte del borde exterior de Ia boca de Ia botella, garantizando así Ia máxima estanqueidad. El segundo anillo Interior tiene una sección en forma de trapecio, aunque puede también ser de otra forma geométrica cualquiera adecuada a su función, tal como triangular, elíptica, semicircular o similares. Se encuentra espaciado respecto al anillo exterior en Ia superficie interior de Ia junta de Ia invención, a una distancia radial del orden de una tercera parte de Ia distancia radial existente entre Ia hendidura del primer anillo exterior y el centro de Ia junta de tapón corona. Es el de menor grosor y altura. En consecuencia, dicho segundo anillo interior comprende una cara superior cuya sección horizontal a su altura media es significativamente menor, aproximadamente Ia mitad, que Ia del primer anillo exterior y está destinado a servir de superficie de contacto con zona de borde de Ia superficie del obturador de Ia botella a fin de lograr estanqueidad por compresión en el acomodo de Ia junta sobre dicho obturador, y en consecuencia el control radial del mismo.SUBSTITUTE SHEET (RULE 26) result of the arrangement of the crown cap on the joint, and in turn on the upper outer edge of the mouth of the bottles. A characteristic feature of said upper face of the first outer ring is to be provided with a central upper groove that in depth reaches approximately half of the height of said first outer ring. Said groove is intended to facilitate, during the placement of the crown plug, the expansion of said outer ring by crushing and the settlement of said outer ring on most of the outer edge of the mouth of the bottle, thus guaranteeing maximum sealing. The second Inner ring has a section in the form of a trapezoid, although it can also be any other geometric shape suitable to its function, such as triangular, elliptical, semicircular or the like. It is spaced with respect to the outer ring on the inner surface of the joint of the invention, at a radial distance of the order of a third of the radial distance between the groove of the first outer ring and the center of the crown plug seal. It is the smallest thickness and height. Consequently, said second inner ring comprises an upper face whose horizontal section at its average height is significantly smaller, approximately half, than that of the first outer ring and is intended to serve as a contact surface with edge area of the shutter surface of the bottle in order to achieve compression tightness in the arrangement of the seal on said shutter, and consequently the radial control thereof.
