Description

CIERRE INTRÍNSECO PARA RECIPIENTE DE PARED FLEXIBLE INTRINSIC CLOSURE FOR FLEXIBLE WALL CONTAINER
DESCRIPCIÓNDESCRIPTION
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La invención se refiere a un cierre intrínseco para recipiente de pared flexible, aplicable a recipientes que, pudiendo tener cualquier configuración y estar cons¬ tituidos en un material flexible, como puede ser plástico resistente, presenta la particularidad de incluir un sistema de cierre particular, que es sencillo, no requiere medios de abroche de ningún tipo y sin embargo produce un cierre eficaz para impedir la salida de un liquido contenido en la propia bolsa.The invention relates to an intrinsic closure for a flexible wall container, applicable to containers that, having any configuration and being constituted in a flexible material, such as resistant plastic, has the particularity of including a particular closing system, which is simple, does not require fastening means of any kind and nevertheless produces an effective closure to prevent the exit of a liquid contained in the bag itself.
CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION
Esta invención tiene su aplicación dentro de la industria dedicada u la fabricación de cierres para recipientes o envases.This invention has its application within the dedicated industry or the manufacture of closures for containers or containers.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Se conoce un tipo de bolsa de pared flexible, constituida preferentemente en plástico suficientemente resistente para que la bolsa pueda contener liquido y que permita su traslado manual sin que se rompa.A type of flexible wall bag is known, preferably constituted in a sufficiently resistant plastic so that the bag can contain liquid and allows its manual transfer without breaking.
Este tipo de bolsas que pueden tener cualquier configuración geométrica, presentan la particularidad de que en la parte superior se define un asa y una estre¬ cha boca de llenado y vaciado, ya que este tipo de bolsas está preferentemente previsto para ser llenada de un liquido en caso de una necesidad momentánea, y/o en cir¬ cunstancias que lo requiera.This type of bags that can have any geometric configuration, have the particularity that in the upper part a handle and a narrow mouth of filling and emptying are defined, since this type of bags is preferably intended to be filled with a liquid in case of a momentary need, and / or in circumstances that require it.
Lo que es evidente, es que al ser una bolsa senci¬ lla y que es económica en su fabricación, la misma no es comercializada con un cierre eficaz, y ni tan siquiera con un cierre que pueda impedir la salida del liquido contenido en la misma en el momento que se produce una inclinación de la bolsa.What is evident is that since it is a simple bag and is economical in its manufacture, it is not commercialized with an effective closure, and not even with a closure that can prevent the liquid contained in it from leaving. at the moment there is an inclination of the bag.
La solución evidente a la problemática existente en la actualidad en esta materia, seria la de poder contar con un cierre intrinseco que permitiera su aplicación en un recipiente de pared flexible, que obviara la exis- tencia de los inconvenientes citados.The obvious solution to the current problem in this area would be to have an intrinsic closure that would allow its application in a flexible wall container, which would obviate the existence of the aforementioned inconveniences.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El cierre intrinseco para recipiente de pared flexible que la invención propone, es aplicable a reci¬ pientes que, aunque pudiendo tener cualquier configura¬ ción y estando constituidos en una pared flexible de cualquier nateraleza, presenta la particularidad de que la boca de llenado y/o vaciado de las mismas, está deter¬ minada por un largo cuello tubular que permite doblar sucesivamente varias veces, quedando en esa posición asegurado por un capuchón que preferentemente estará unido al recipiente y que puede ser obtenido de sus pare¬ des durante la fase de conformación del misino.The intrinsic closure for flexible wall container that the invention proposes is applicable to containers that, although having any configuration and being constituted in a flexible wall of any nature, have the particularity that the filling mouth and / or emptying them, it is determined by a long tubular neck that allows bending several times successively, being in that position secured by a cap that will preferably be attached to the container and that can be obtained from its walls during the phase of conformation of the misino.
De esta manera se consigue un cierre totalmente eficaz que permite que el recipiente contenga un liquido y este no caiga aunque dicho recipiente sea inclinado, o incluso tumbado, lo que permite su transporte cargado de liquido en un vehiculo o en cualquier otro medio con- vencional, es decir sin necesidad de tenerlo que llevar continuamente agarrado por el asa en la posición erecta para el mismo.In this way a totally effective closure is achieved that allows the container to contain a liquid and this does not fall even if said container is inclined, or even lying down, which allows its transport loaded with liquid in a vehicle or in any other means venational, that is to say, without having to carry it continually held by the handle in the erect position for it.
Como se habrá podido comprobar, el cierre es sumamente sencillo, puesto que se basa en un largo cuello que en virtud de su longitud permite una sucesión de dobleces del mismo, quedando este una vez totalmente plegado por esos dobleces en el interior de un capuchón vinculado al propio recipiente, formando dicho capuchón parte integrante de aquel y bastando con traccionar de tal capuchón para liberar el cuello y posibilitar el vaciado del líquido contenido en el propio recipiente, que por otra parte al contar con un cuello de salida de considerable longitud, posibilita un vaciado sensible¬ mente más eficaz y racional que cuando el recipiente incluye una simple abertura de salida del líquido.As it can be seen, the closure is extremely simple, since it is based on a long neck that by virtue of its length allows a succession of folds thereof, being this once fully folded by those folds inside a linked cap to the container itself, said cap forming an integral part of it and it is sufficient to pull such a cap to release the neck and enable the emptying of the liquid contained in the container itself, which on the other hand by having an exit neck of considerable length, enables a drainage significantly more efficient and rational than when the container includes a simple liquid outlet opening.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de estas figuras puede observarse como el cierre intrínseco para recipiente de pared flexi- ble está constituido a partir de una bolsa (1), que como ya se ha dicho anteriormente puede tener cualquier confi¬ guración y estar dotada de paredes flexibles, aunque estas pueden estar configuradas en cualquier naturaleza, presentando la particularidad de que la parte superior de la misma, es decir de la bolsa, incluye un cordón de soldadura (2) que la cierra prácticamente en su totali¬ dad a excepción de un tramo (3) determinante de la boca de llenado y vaciado para la bolsa, contando esta por encima de la linea de soldadura (2) con un asa (A) para el transporte manual de aquella.In view of these figures, it can be seen how the intrinsic closure for a flexible wall container is constituted from a bag (1), which, as already mentioned above, can have any configuration and be provided with flexible walls, although these can be configured in any nature, presenting the particularity that the upper part of it, that is to say of the bag, includes a weld bead (2) that closes it almost completely except for a section ( 3) determinant of the mouth of filling and emptying for the bag, counting this above the welding line (2) with a handle (A) for the manual transport of that.
Pues bien, la novedad de la bolsa (1), consiste en que la abertura (3) que se origina en la parte superior de la bolsa (1), se prolonga en un largo cuello tubular (5), con una longitud suficiente que posibilite el dobladoWell, the novelty of the bag (1), is that the opening (3) that originates in the upper part of the bag (1), extends into a long tubular neck (5), with a sufficient length that enable bending
HOJA DE SUSTITUCIÓN (REGLA 26) sucesivamente varias veces, para formar o configurar un plegado (6),' que quedará alojado en un capuchón (7) que forma parte del propio cuerpo de la bolsa (1) y vincu¬ lado a ella a través de un tirante (8), por lo cual ese capuchón (7) y el propio tirante (8), están permanentemen¬ te unidos a la bolsa y pueden ser obtenidos en la propia conformación de la misma, es decir de la bolsa.SUBSTITUTE SHEET (RULE 26) successively several times, to form or configure a fold (6), 'which will be housed in a cap (7) that is part of the body of the bag (1) and linked to it through a strap (8) , whereby that cap (7) and the strap itself (8), are permanently attached to the bag and can be obtained in its own conformation, that is, the bag.
Como se habrá podido comprobar, el cierre asi conseguido resulta totalmente eficaz, ya que el plegado (6) del cuello (5) por sucesivos dobleces, impiden la más minima salida del liquido contenido en la bolsa (1), con la particularidad de que tal plegado (6) del cuello (5), permanece en su posición al quedar alojado ajustada¬ mente en el interior del mismo del capuchón (7), siendo necesario traccionar manualmente de éste para desvincular¬ lo de ese plegado (6) y poder llevar a cabo el desdobla¬ do del mismo y, en consecuencia, el estiramiento del cuello (5) para permitir la salida del liquido contenido en la bolsa.As it has been possible to verify, the closure thus achieved is totally effective, since the folding (6) of the neck (5) by successive folds, prevents the slightest outflow of the liquid contained in the bag (1), with the particularity that such folding (6) of the neck (5), remains in position when it is lodged tightly inside the hood (7), it being necessary to manually pull it to detach it from that folding (6) and power carry out the unfolding of the same and, consequently, stretching the neck (5) to allow the liquid contained in the bag to escape.
Aunque el recipiente representado en los dibujos adjuntos, está configurado a manera de una bolsa, como puede comprenderse puede adoptar cualquier forma y estar destinado a contener productos líquidos o semiliquidos, pulverulentos o de tipo granular, incluso de naturaleza gaseosa, ya que el cierre logrado puede llegar a ofrecer una hermeticidad total. Although the container represented in the attached drawings, is configured as a bag, as can be understood it can take any form and be intended to contain liquid or semi-liquid, powdery or granular products, even of a gaseous nature, since the closure achieved It can offer a total tightness.
