Abstract

The invention relates to a re-usable cap for pressurised cylinders of the type that comprise a cap body or lid having a protector that is weakened by grooving. A crown is placed on top of the lid, surrounding said lid. The inventive device is essentially characterised in that the exterior of the protector of the inner body of the cap is provided with helical grooves for receiving ridges which are disposed on the inner surface of the crown. The ridges of the crown slide into the helical grooves of the inner body, in order to join both bodies together into one single piece, and define two axial positions for said crown on top of the inner body, compressing or decompressing the closing protector on the neck of the bottle, thereby closing and opening said neck with a simple turn of the cap.

Description

TAPÓN REUTILIZABLE PARA BOTELLAS A PRESIÓN. MEMORIA DESCRIPTIVA. OBJETO DE LA INVENCIÓN. La presente solicitud de Patente de Invención tiene por objeto el registro de un tapón reutilizable para botellas a presión que incorpora notables innovaciones y ventajas frente a los actuales tapones y medios de cierre de botellas y envases. REUSABLE PLUG FOR PRESSURE BOTTLES. DESCRIPTIVE MEMORY. OBJECT OF THE INVENTION The purpose of the present invention patent application is to register a reusable cap for pressurized bottles that incorporates notable innovations and advantages over the current caps and means of closing bottles and containers.
Más concretamente la nueva invención consiste en un tapón de fácil apertura que está constituido en dos cuerpos, un cuerpo o tapón de cierre y un cuerpo anular exterior de aseguramiento con un funcionamiento a semejanza de un tapón de cierre a presión, pero que es capaz de soportar ciertas presiones como un tapón de rosca. Este tapón se ha ideado para su uso en el cierre de botellas y envases de bebidas carbónicas que contienen cierta presión, aunque su uso también se extiende al cierre de bebidas no carbónicas o sin presión añadida. ANTECEDENTES DE LA INVENCIÓN.More specifically, the new invention consists of an easy-to-open plug that is constituted in two bodies, a closing body or cap and an outer annular securing body with an operation similar to a pressure closure cap, but which is capable of withstand certain pressures like a screw cap. This cap has been designed for use in the closure of bottles and containers of carbonated beverages that contain some pressure, although its use also extends to the closure of non-carbonated beverages or without added pressure. BACKGROUND OF THE INVENTION
Actualmente en el mercado hay disponibles una gran variedad de tapones y cierres para botellas de bebidas . Las bebidas carbónicas presentan además un problema añadido debido a su contenido en gas que presuriza el envase y hace inviable el uso de cierres no resistentes al esfuerzo de compresión que deben resistir.A wide variety of caps and closures for beverage bottles are currently available on the market. The carbonated drinks also present an additional problem due to their gas content that pressurizes the container and makes it impossible to use closures not resistant to the compressive stress they must resist.
Son comunes los tapones de rosca en los envases de bebidas carbónicas. Dichos tapones están constituidos por una cápsula cilindrica que en su interior presenta una o más espiras que se enroscan con otras espiras resaltadas que existen en el gollete de la botella.Screw caps are common in carbonated beverage containers. Said plugs are constituted by a cylindrical capsule that inside has one or more spirals that are screwed with other highlighted turns that exist in the neck of the bottle.
También son conocidos los tapones corona, constituidos por una lámina de metal circular que se encuentra plegada sobre el gollete de la botella. Es un sistema barato y rápido de cierre, pero necesita una herramienta para su extracción y además no permite volver a cerrar el envase.Crown caps are also known, consisting of a circular metal sheet that is folded over the neck of the bottle. It is a cheap and fast closing system, but it needs a tool for its extraction and also does not allow the container to be closed again.
También existen tapones con cierre a presión, tales como corchos o cápsulas que se mantienen por encaje en resaltes circundantes existentes en el gollete. Muchos de estos tapones una vez abiertos no se pueden volver a utilizar para cerrarlos o si se proyectan para soportar presiones son difíciles de abrir. Debido a esto, ciertos tapones a presión tienen un escaso uso en la industria de las bebidas carbónicas, salvo en el caso de que se prevea desprenderse del tapón cuando se ha abierto el envase, caso del champaña, cerveza y otras bebidas. También existen los tapones descritos en los modelos de utilidad n° 9902575 y n° 9902322, de titularidad del solicitante, que son variantes del concepto del tapón constituido por un faldón que presenta un nervio interior circundante de encajado entre dos resaltes del gollete, estando su faldón ranurado verticalmente y coadyuvado en su operación de cierre del gollete por un anillo circundante y movible axialmente. Dicho tapón está cerrado cuando el anillo circundante se coloca alrededor del tapón de cierre, comprimiendo el nervio interior contra los resaltes del gollete y se abre por la extracción del anillo circundante, cuya ausencia conlleva la relajación del faldón ranurado, permitiendo su fácil extracción. Este tipo de tapón presenta inconvenientes de uso, dado que el tapón está constituido por dos piezas independientes, con lo cual si el usuario pierde una pieza no puede cerrar la botella y además existe el riesgo que al extraer el anillo exterior, en el caso de envases a presión, el tapón salga disparado por una falta de sujeción, con el consecuente riesgo. DESCRIPCIÓN DE LA INVENCIÓN. El tapón reutilizable para botellas a presión objeto del presente registro, se caracteriza porque comprende una única estructura de cierre de tapón, apto para su utilización en envases con golletes de contorno anular o similar, por ejemplo de las botellas para cierre por tapón corona o similares.There are also caps with snap closure, such as corks or capsules that are held in place by surrounding projections on the neck. Many of these once opened plugs cannot be reused to close them or if they are designed to withstand pressures they are difficult to open. Due to this, certain pressure caps have little use in the carbonated beverage industry, except in the event that it is expected to discard the cap when the container has been opened, in case of champagne, beer and other beverages. There are also the plugs described in the utility models n ° 9902575 and n ° 9902322, owned by the applicant, which are variants of the concept of the cap consisting of a skirt that has a surrounding inner rib embedded between two projections of the neck, its skirt being grooved vertically and assisted in its operation of closing the neck by a surrounding ring and axially movable. Said cap is closed when the surrounding ring is placed around the closure cap, compressing the inner rib against the projections of the neck and is opened by the removal of the surrounding ring, the absence of which involves the relaxation of the slotted skirt, allowing easy removal. This type of cap presents inconveniences of use, since the cap is constituted by two independent pieces, whereby if the user loses a piece he cannot close the bottle and there is also the risk that when removing the outer ring, in the case of Pressurized containers, the cap comes out triggered by a lack of support, with the consequent risk. DESCRIPTION OF THE INVENTION The reusable cap for pressurized bottles object of the present registration, is characterized in that it comprises a single cap closure structure, suitable for use in containers with annular contour struts or the like, for example of the bottles for closure by crown cap or the like .
Efectivamente el tapón de nueva invención está constituido por dos cuerpos que presentan un movimiento relativo mutuo, pero que son inseparables. El cuerpo interior del tapón presenta forma cilindrica y está proyectada en un faldón que presenta una serie de ranuras longitudinales que definen una debilitación relativa del mismo. Este faldón presenta en su contorno exterior dos surcos helicoidales que abarcan aproximadamente entre un cuarto y casi la mitad de vuelta alrededor del contorno. Alrededor de dicho tapón se encuentra instalada una corona de compresión, la cual presenta en su cara interior dos tetones o salientes corredizos, alojados respectivamente en las ranuras del cuerpo interior. Al girar la corona exterior sobre el cuerpo interior se produce un movimiento en hélice que determina un desplazamiento axial de la corona respecto el cuerpo interior del tapón.Indeed, the cap of the new invention consists of two bodies that have a relative mutual movement, but are inseparable. The inner body of the cap has a cylindrical shape and is projected on a skirt that has a series of longitudinal grooves that define a relative weakening thereof. This skirt has two helical grooves in its outer contour, covering approximately a quarter to almost half a turn around the contour. A compression crown is installed around said cap, which has two sliding lugs or projections on its inner face, respectively housed in the grooves of the inner body. Turning the outer crown over the inner body produces a helix movement that determines a displacement axial crown relative to the inner body of the cap.
De esta forma el tapón presenta dos posiciones estables. La primera posición consiste en la corona dispuesta completamente sobre el cuerpo interior del tapón. En esta posición dicho cuerpo interior se encuentra aprisionado por la corona exterior contra el gollete, asegurando el cierre de la botella o envase, los tetones interiores de la corona exterior se encuentran dispuestos en el extremo inferior del surco en helicoide existente en el contorno del cuerpo interior. La segunda posición consiste en la corona dispuesta desplazada axialmente sobre el cuerpo interior del tapón, fuera del área de interferencia del faldón interior, con lo que dicho faldón se encuentra relajado. En esta posición los tetones deslizantes se encuentran dispuestos en la parte superior del surco helicoidal.In this way the cap has two stable positions. The first position consists of the crown completely arranged on the inner body of the cap. In this position said inner body is trapped by the outer crown against the neck, ensuring the closure of the bottle or container, the inner lugs of the outer crown are arranged at the lower end of the helical groove existing in the body contour inside. The second position consists of the crown arranged axially displaced on the inner body of the cap, outside the interference area of the inner skirt, whereby said skirt is relaxed. In this position the sliding lugs are arranged in the upper part of the helical groove.
Al girar la corona exterior sobre el cuerpo interior se produce un movimiento en hélice que determina un desplazamiento axial hacia la parte superior del tapón con lo que se relaja la presión realizada sobre el faldón de cierre del cuerpo interior. Al estar liberado el faldón inferior de la compresión de la corona exterior se produce una desgasificación controlada del interior. Todo ello se realiza con el tapón sujeto con la mano, evitando así que dicho tapón salga despedido por la presión interior. Para acabar de desprender el tapón solo es necesario realizar un pequeño movimiento de balanceo que desplaza el nervio interior del tapón del acoplamiento con el gollete. La abertura del tapón es de forma natural, un giro aproximadamente inferior a la mitad de una vuelta y una balanceo o basculación del tapón en un plano transversal permiten extraer el tapón con facilidad. Para cerrar el tapón solo es necesario aplicarlo sobre el gollete con ligera presión y girar la corona externa en sentido contrario. En dicho movimiento la corona se desplaza axialmente sobre el cuerpo interior dado que los tetones interiores se desplazan en la ranura helicoidal en que están alojados. Dicho movimiento axial de la corona sobre el cuerpo interior comprime a este segundo contra el gollete, asegurando el cierre de la botella o envase.Turning the outer crown on the inner body produces a helix movement that determines an axial displacement towards the top of the cap, thereby relaxing the pressure on the closing skirt of the inner body. When the lower skirt of the compression of the outer crown is released, a controlled degassing of the interior occurs. All this is done with the cap held by hand, thus preventing said cap from being fired by the internal pressure. To finish detaching the plug, it is only necessary to perform a small swinging movement that displaces the inner rib of the coupling plug with the neck. The opening of the cap is naturally, a turn approximately less than half a turn and a swinging or tilting of the plug in a transverse plane make it easy to remove the plug. To close the cap it is only necessary to apply it on the neck with slight pressure and turn the outer crown in the opposite direction. In said movement, the crown moves axially on the inner body since the inner lugs move in the helical groove in which they are housed. Said axial movement of the crown on the inner body compresses this second against the neck, ensuring the closure of the bottle or container.
El surco helicoidal presenta por lo tanto dos fines de carrera de los tetones en su interior. La corona se encuentra relativamente fijada sobre el cuerpo interior del tapón gracias a estos tetones, con lo que se consigue que el tapón sea manipulable en una sola pieza compacta. A fin de mejorar la estanqueidad del tapón se ha previsto que el cuerpo interior del tapón presente un circuito laberíntico de salida de fluidos. Este circuito está constituido por un labio interior circundante que existe en la cara interior de la base del cuerpo del tapón, dicho labio presenta su contorno redondeado y encaja en el contorno interior del gollete, ajustando por flexión. El circuito laberíntico se encuentra coadyuvado por un resalte circundante opuesto a dicho labio, existente en el nacimiento del faldón de cierre. Dicho resalte además refuerza la estructura del cuerpo interior del tapón. Por último el nervio interior de anclaje del tapón también contribuye a la estanqueidad del cierre, a pesar de está debilitado en las zonas afectadas por las ranuras longitudinales. La parte interior de la base del tapón presenta una serie de nervios de refuerzo inscritos radialmente en el área encerrada por el labio de ajuste. Dichos refuerzos evitan que el tapón se abombe por la presión y aseguran que no se produzca falta de estanqueidad por deformación del faldón. La corona exterior está constituida preferentemente por una doble cascara o contorno cilindrico, estando ambos cilindros relacionados con nervios de refuerzo dispuestos entre ellas, el contorno interior es la parte destinada a comprimir el faldón interior y presenta en su superficie los dos tetones deslizantes alojados en los surcos helicoidales. Para facilitar su montaje dichos tetones, en un número preferente de dos, se encuentran opuestos entre sí y montados sobre respectivas lengüetas, de forma que flexionen al introducir la corona sobre el cuerpo interior. Dicha lengüeta no presenta ningún nervio de refuerzo en su parte posterior para mantener la flexibilidad. La corona también presenta un cilindro exterior, unido al cilindro interior en el contorno superior y a través de los mencionados nervios de refuerzo. Dicho cilindro exterior es la parte de asido resistente, pudiendo presentar un grabado para propiciar su agarre y está prolongado inferiormente en un anillo labiado a modo de precinto de seguridad convencional, unido mediante unos puntos de unión desgarrables y apto para estar trabado en un resalte anular del faldón del propio tapón. Un giro del tapón en sentido de abertura hace que dicho anillo se desprenda, quedando manifiesta su abertura .The helical groove therefore presents two ends of the studs inside. The crown is relatively fixed on the inner body of the cap thanks to these lugs, so that the cap can be manipulated in a single compact piece. In order to improve the tightness of the plug it is provided that the inner body of the plug has a labyrinthine fluid outlet circuit. This circuit is constituted by a surrounding inner lip that exists on the inner face of the base of the cap body, said lip has its rounded contour and fits into the inner contour of the neck, adjusting by flexion. The labyrinthine circuit is assisted by a surrounding projection opposite to said lip, existing at the birth of the closing skirt. Said projection also reinforces the structure of the inner body of the cap. Finally the inner anchoring nerve of the plug It also contributes to the tightness of the closure, although it is weakened in the areas affected by the longitudinal grooves. The inner part of the base of the cap has a series of reinforcement ribs radially inscribed in the area enclosed by the adjustment lip. These reinforcements prevent the plug from bulging due to pressure and ensure that there is no lack of tightness due to deformation of the skirt. The outer crown is preferably constituted by a double shell or cylindrical contour, both cylinders being related to reinforcement ribs arranged between them, the inner contour is the part intended to compress the inner skirt and has on its surface the two sliding lugs housed in the helical grooves To facilitate their assembly, said lugs, in a preferred number of two, are opposite each other and mounted on respective tongues, so that they flex when introducing the crown on the inner body. Said tongue does not have any reinforcement ribs in its back to maintain flexibility. The crown also has an outer cylinder, attached to the inner cylinder in the upper contour and through said reinforcement ribs. Said outer cylinder is the resistant gripping part, being able to present an engraving to propitiate its grip and is extended inferiorly in a ring carved as a conventional security seal, connected by means of tear-off junction points and suitable to be locked in an annular shoulder. of his own skirt plug. A rotation of the plug in the direction of opening causes said ring to detach, its opening being manifest.
