Description

Dispositivo de extracción por presión sin gas de líquidos. Pressure extraction device without liquid gas.

Object of the Invention

La presente invención se refiere a un dispositivo de extracción por presión sin gas de líquidos, que aporta esenciales características de novedad y notables ventajas con respecto a los medios conocidos y utilizados para los mismos fines en el estado actual de la técnica. The present invention relates to a gas-free pressure extraction device for liquids, which provides essential novelty characteristics and notable advantages over known means and used for the same purposes in the current state of the art.

Más en particular, la invención desarrolla un dispositivo especialmente diseñado para su aplicación a la extracción de un líquido contenido en el interior de un recipiente en virtud de la presión del interior del recipiente, pero sin necesidad de utilizar ningún tipo de gas combinado con el líquido. More particularly, the invention develops a device specially designed for application to the extraction of a liquid contained inside a container by virtue of the pressure inside the container, but without using any type of gas combined with the liquid .

El dispositivo comprende elementos constitutivos de dos compartimentos principales, superpuestos y vinculados entre sí, de los que un primer compartimento se acopla herméticamente al cuello del recipiente contenedor (por ejemplo, una botella de refresco) y constituye el cierre de dicho cuello, y un segundo compartimento, portador de un tubo de salida para suministro del líquido contenido en el recipiente, está en comunicación de fluido con el interior del recipiente por medio de un tubo principal de extracción y llenado que por el extremo opuesto (es decir, el extremo del tubo sumergido en el líquido del interior del recipiente contenedor), está cerrado por medio de una válvula obtenida mediante un material elástico extensible. La válvula es accionable por medio de una varilla que recorre el mencionado tubo de extracción y llenado, para lo cual se ha dotado en su extremo proximal de un botón accionable manualmente a través de una membrana elástica protegida por una tapa que se abre opcionalmente, que cierra un tercer compartimento o tapa superior, acoplado a dicho segundo compartimento. The device comprises elements constituting two main compartments, superimposed and interconnected, of which a first compartment is tightly coupled to the neck of the container (for example, a soda bottle) and constitutes the closure of said neck, and a second compartment, carrier of an outlet tube for supply of the liquid contained in the container, is in fluid communication with the interior of the container by means of a main extraction and filling tube that by the opposite end (i.e. the end of the tube submerged in the liquid inside the container container), it is closed by means of a valve obtained by means of an extensible elastic material. The valve is operable by means of a rod that runs through said extraction and filling tube, for which a manually operated button is provided at its proximal end through an elastic membrane protected by an optionally open lid, which close a third compartment or top cover, coupled to said second compartment.

Technical Sector

El campo de aplicación de la invención se encuentra comprendido dentro del sector industrial dedicado a la fabricación y suministro de medios para la extracción de fluidos mediante presión. The scope of the invention is within the industrial sector dedicated to the manufacture and supply of means for the extraction of fluids by pressure.

Background

Es conocido por todos en general la existencia en el mercado de productos líquidos, del tipo de refrescos o similares, encerrados en contenedores o envases provistos de medios de válvula de salida que al ser pulsada manualmente desde el exterior por el usuario, produce la salida instantánea del producto líquido contenido en el interior del envase. La salida del producto líquido está ocasionada por el valor incrementado de la presión existente en el interior del envase con respecto a la presión externa, para lo cual se ha introducido previamente en dicho envase un gas a presión que actúa como propelente y que empuja por tanto al líquido a través del conducto de salida en el que se halla ubicada la válvula de salida. It is known by all in general the existence in the market of liquid products, of the type of soft drinks or similar, enclosed in containers or containers provided with outlet valve means that when manually pressed from the outside by the user, produces instant output of the liquid product contained inside the container. The exit of the liquid product is caused by the increased value of the pressure inside the container with respect to the external pressure, for which a pressure gas that acts as a propellant and that therefore pushes therefore has been previously introduced into said container to the liquid through the outlet duct in which the outlet valve is located.

Aunque está demostrado que los gases utilizados como propelentes son inocuos para la salud del consumidor, seria no obstante deseable que el producto líquido contenido en el interior de un envase o contenedor, pudiera ser extraído sin necesidad de utilizar ningún gas o producto adicional combinado con el mismo. Although it is shown that the gases used as propellants are harmless to the health of the consumer, it would nevertheless be desirable that the liquid product contained inside a container or container could be extracted without using any additional gas or product combined with the same.

State of the Art

La presente invención se ha propuesto como objetivo principal el desarrollo de un dispositivo mediante el que se facilite la salida del producto líquido encerrado en el interior del envase sin necesidad de propelentes gaseosos adicionales. Este objetivo ha sido plenamente alcanzado mediante el dispositivo que va a ser objeto de descripción en lo que sigue, cuyas características principales aparecen recogidas en la porción caracterizadora de la reivindicación 1 anexa. The present invention has as its main objective the development of a device whereby the exit of the liquid product enclosed inside the container is facilitated without the need for additional gaseous propellants. This objective has been fully achieved by means of the device to be described in the following, whose main characteristics are included in the characterizing portion of the attached claim 1.

Detailed description of the invention

De acuerdo con la invención, el dispositivo propuesto ocasiona la salida del producto líquido encerrado en el interior del envase, utilizando para ello la sobrepresión que se origina en la atmósfera interior cuando se produce el llenado del producto sin dejar escapar el aire del interior. Para ello, el dispositivo ha diseñado un conjunto compuesto por dos elementos constitutivos de compartimentos respectivos que proporcionan espacios o cavidades internas correspondientes, de las que un primer compartimento se utiliza como tapón de cierre hermético de la embocadura del envase o contenedor, y un segundo compartimento, acoplado al primero y superpuesto a este último, tiene su espacio interno en comunicación de fluido con el interior del envase merced a la provisión de un tubo de extracción y llenado cuyo extremo proximal desemboca en el espacio interior de dicho segundo compartimento tras atravesar la pared superior del primer compartimento, y cuyo extremo distal está sumergido en el interior del líquido contenido en According to the invention, the proposed device causes the liquid product inside the container to escape, using the overpressure that originates in the interior atmosphere when the product is filled without letting the air inside. For this, the device has designed a set consisting of two constituent elements of respective compartments that provide corresponding internal spaces or cavities, of which a first compartment is used as a hermetic closure cap of the mouth of the container or container, and a second compartment , coupled to the first and superimposed on the latter, has its internal space in fluid communication with the interior of the container thanks to the provision of an extraction and filling tube whose proximal end flows into the interior space of said second compartment after crossing the wall upper of the first compartment, and whose distal end is submerged inside the liquid contained in

el envase y acoplado a un soporte en cuyo interior se aloja una válvula compuesta por un material elástico extensible que por medio de cuerdas elásticas radiales está fijada a dicho soporte. El espacio interior del segundo compartimento, en el que desemboca el extremo proximal del mencionado tubo de extracción y llenado, esta en comunicación con el exterior a través de un tubo de salida o suministro de líquido, susceptible de ser cerrado en su extremo con la utilización de un tapón apropiado. En el interior del tubo de salida, esta ubicada una válvula esférica que esta presionada por un hilo elástico, el cual mantiene conservado el líquido existente entre las dos válvulas, tras la primera utilización. the container and coupled to a support inside which a valve composed of an extensible elastic material is housed which, by means of radial elastic cords, is fixed to said support. The interior space of the second compartment, at which the proximal end of said extraction and filling tube flows, is in communication with the outside through an outlet or liquid supply tube, which can be closed at its end with the use of an appropriate plug. Inside the outlet tube, a spherical valve is located that is pressed by an elastic thread, which keeps the existing liquid between the two valves, after the first use.

Por el interior de dicho tubo principal de extracción y llenado, se extiende una varilla de empuje que por el extremo interior o distal, apoya contra una porción terminal de la mencionada válvula elástica extensible, mientras que por el extremo exterior o proximal incluye un botón que puede ser accionado por el usuario a través de una membrana elástica extensible protegida por una tapa que se abre opcionalmente, asociada a un tercer compartimento susceptible de apoyo y fijación sobre el segundo compartimento ya citado, y cuya membrana elástica extensible queda en posición enfrentada a dicho botón asociado a la citada varilla de empuje. Inside said main extraction and filling tube, a push rod is extended which, on the inner or distal end, rests against a terminal portion of said extensible elastic valve, while on the outer or proximal end it includes a button that it can be operated by the user through an extensible elastic membrane protected by an optionally opening lid, associated with a third compartment susceptible to support and fixation on the second compartment already mentioned, and whose extensible elastic membrane is in a position facing said button associated with said push rod.

Con esta disposición, el llenado del líquido hacia el interior del contenedor se realiza desde el extremo proximal del tubo de extracción y llenado, por cesión elástica de la mencionada válvula elástica extensible que cierra herméticamente el extremo distal de dicho tubo principal, creando con ello la deseada sobrepresión en el interior del envase contenedor. With this arrangement, the filling of the liquid into the container is carried out from the proximal end of the extraction and filling tube, by elastic transfer of the said extensible elastic valve that hermetically closes the distal end of said main tube, thereby creating the desired overpressure inside the container container.

La segunda modalidad de llenado con líquido: en el interior de un contenedor con capacidad de un litro se introduce una cantidad de 850 (ochocientos cincuenta) mililitros de líquido, el dispositivo se acopla al contenedor y por el extremo proximal del tubo de extracción se llena de aire hasta que la presión interior llega a (4) (cuatro) atmósferas. The second mode of filling with liquid: inside a container with a capacity of one liter an amount of 850 (eight hundred and fifty) milliliters of liquid is introduced, the device is coupled to the container and by the proximal end of the extraction tube is filled of air until the internal pressure reaches (4) (four) atmospheres.

En estas condiciones, cuando se desea extraer líquido, basta con presionar sobre la membrana elástica que toca el botón asociado al extremo superior de la varilla de empuje para ocasionar el desplazamiento de ésta y empujar la válvula elástica vinculada al extremo distal del tubo de extracción y llenado, de modo que la sobrepresión del interior del envase ocasiona el ascenso del líquido a través de dicho tubo de extracción y llenado hasta el espacio o cavidad interior del segundo compartimento, y desde éste hacia el exterior a través del tubo de salida o suministro, y gracias a la presión de salida por cesión elástica del hilo elástico, el líquido empuja a la válvula esférica para que este se ubique dentro del tubo secundario, y el líquido salga al exterior; cuando la presión del líquido baja, el hilo elástico extensible tira hacia el interior la segunda válvula esférica, tapando perfectamente el tubo de salida del líquido y manteniendo perfectamente conservado el líquido existente entre las dos válvulas, tras la primera utilización. Under these conditions, when it is desired to extract liquid, it is enough to press on the elastic membrane that touches the button associated to the upper end of the pushrod to cause its displacement and push the elastic valve linked to the distal end of the extraction tube and filled, so that overpressure of the inside of the container causes the liquid to rise through said extraction and filling tube to the interior space or cavity of the second compartment, and from it to the outside through the outlet or supply tube, and thanks to the outlet pressure by elastic transfer of the elastic thread, the liquid pushes the spherical valve so that it is located inside the secondary tube, and the liquid goes outside; when the pressure of the liquid drops, the stretchable elastic thread pulls the second spherical valve inwards, perfectly covering the liquid outlet tube and keeping the existing liquid between the two valves perfectly preserved, after the first use.
