La copa de montaje 121 tiene una parte inferior 122 montada calzadamente contra un escalón 123 definido entre el labio perimetral 109 de la boca abierta 108 y el cuello 107, y una porción superior a través de la cual pasa dicho vástago de válvula 1 14. Si la férula 121 es metálica, la parte inferior 122 de la misma se producirá por crimpado del borde sobre el escalón 123 para generar la retención suficiente de la válvula en el cuello o boca del cuerpo del envase. On the other hand, said valve stem is mounted guided by an internal seal 119 which, in turn, is retained by a ring seal 120 which also acts as a guide to said valve stem 1 14. Both the seal of internal seal 119 as ring seal 120, are retained within a ferrule or mounting cup 121 which is mounted outside the open mouth 108 and part of the neck 107, thus being that said ring seal 120 is retained against the internal walls of the mounting cup 121 and the open mouth 108 of the container body 102. The mounting cup 121 has a lower part 122 mounted wedged against a step 123 defined between the perimeter lip 109 of the open mouth 108 and the neck 107, and an upper portion through which said valve stem 1 14 passes. If the ferrule 121 is metallic, the lower part 122 thereof will be produced by crimp the edge on the step 123 to generate sufficient retention of the valve in the neck or mouth of the container body.
Sin embargo, dado que, a diferencia de los cuerpos convencionales hechos de metal, el presente cuerpo, gracias a su novedosa conformación puede ser hecho de un material plástico, la férula 121 también puede ser hecha de material plástico con su parte inferior a modo de traba por calce elástico sobre el escalón 123 del cuello del envase. Considerando que el cuerpo y la férula son ambos de plástico, una vez montada por calce elástico, el borde de la parte inferior 122 de la férula puede ser fijada al cuerpo del envase por cualquier técnica conocida, por ejemplo, por medio de una fijación seleccionada entre presión, adhesivo, soldadura térmica, fricción, ultrasonido y combinación de algunas de las mismas. Esto permite una mejor retención y sellado conjunto. Esto es muy importante a la hora de llenar el envase con el producto bajo presión. En los cierres por medio de férulas metálicas y cuerpos metálicos convencionales, si el cierre no es perfecto la presión, siendo tan importante, puede producir pérdidas entre la férula y el cuerpo. Si, de acuerdo con la invención, la férula es plástica y se adhiere por las técnicas mencionadas al cuerpo, esto nunca ocurrirá. Esto permite aumentar la velocidad de llenado del envase. However, since, unlike conventional bodies made of metal, the present body, thanks to its novel conformation can be made of a plastic material, the ferrule 121 can also be made of plastic material with its lower part in the manner of lock by elastic fit on the step 123 of the neck of the container. Considering that the body and the splint are both made of plastic, once assembled by elastic fit, the edge of the lower part 122 of the splint can be fixed to the body of the package by any known technique, for example, by means of a selected fixation between pressure, adhesive, thermal welding, friction, ultrasound and combination of some of them. This allows for better joint retention and sealing. This is very important when filling the container with the product under pressure. In the closures by means of metal splints and conventional metal bodies, if the closure is not perfect the pressure, being so important, can cause losses between the splint and the body. If, according to the invention, the splint is plastic and adheres by the techniques mentioned to the body, this never it will happen This allows to increase the filling speed of the container.
Dicho alojamiento 110 es tubular y se dispone concéntricamente con respecto al cuello 107 del cuerpo contenedor 102 y por debajo del mismo, estando fijo flotantemente mediante respectivos puentes de soporte 124 los cuales se encuentran distanciados entre sí, definiendo una pluralidad de pasajes de comunicación 125 entre el interior del cuerpo contenedor y una cámara de dosificación 126 definida entre las paredes internas del cuello 107 del cuerpo contenedor 102, el vástago de válvula 114, la junta de anillo 120 y la junta de sello interna 1 19. Dicha cámara de dosificación 126 se encuentra en comunicación con los pasajes 125 de manera de permitir el ingreso del producto dosificable en el conjunto de válvula 112 y así, permitir que el producto pase a través de los pasajes axiales 1 17 para ingresar en el pasaje 116 del vástago de válvula 114 y egrese del conjunto de válvula hacia una disposición externa o medio externo complementario que permite la inhalación del producto dosificable. Said housing 110 is tubular and is arranged concentrically with respect to the neck 107 of the container body 102 and below it, being fixed floatingly by means of respective support bridges 124 which are spaced apart from one another, defining a plurality of communication passages 125 between the interior of the container body and a metering chamber 126 defined between the internal walls of the neck 107 of the container body 102, the valve stem 114, the ring seal 120 and the internal seal 1 19. Said metering chamber 126 it is in communication with the passages 125 in order to allow the dosable product to enter the valve assembly 112 and thus allow the product to pass through the axial passages 1 17 to enter the passage 116 of the valve stem 114 and exit from the valve assembly towards an external arrangement or complementary external medium that allows inhalation of the product dosable
Tal como se ha descrito en la sección del arte previo, se entiende que los conjuntos de válvula son bien conocidos en el campo del arte y que su funcionamiento no varía uno del otro dado que operan bajo el mismo concepto operativo, y que, por tales motivos, no se describirá en forma detallada en la presente descripción. As described in the prior art section, it is understood that valve assemblies are well known in the art field and that their operation does not vary from one another since they operate under the same operating concept, and that, for reasons will not be described in detail in the present description.
De esta forma, se encuentra constituido y construido el envase con válvula dosificadora de la presente invención, el cual mejora los procesos productivos para su fabricación gracias a que está realizado en un material polimérico y, además, facilita el ensamble de las respetivas partes dado que reduce la cantidad de elementos a utilizar y siendo así que se reducen tiempos operativos. Es así que, una vez que se obtiene el envase contenedor por cualquier método conocido en el arte, simplemente se debe colocar las partes respectivas al resorte 1 10, junta de anillo 120, junta de sello interna 119, copa de montaje 121 y vástago de válvula 114, que garantizan un total sello y hermeticidad para evitar posibles fugas. In this way, the container with dosing valve of the present invention is constituted and constructed, which improves the production processes for its manufacture thanks to the fact that it is made of a polymeric material and, in addition, facilitates the assembly of the respective parts since reduces the number of elements to be used and thus reducing operating times. Thus, once the container container is obtained by any method known in the art, the respective parts should simply be placed to the spring 1 10, ring seal 120, internal seal 119, mounting cup 121 and shank valve 114, which guarantee a total seal and airtightness to avoid possible leaks.
A su vez, el diseño y configuración estructural en forma de cúpula de la porción superior del contenedor 102, evita la acumulación de producto a dosificar en su interior mejorando la comunicación entre el interior del mismo y la cámara de dosificación, por lo que, todo el producto es dosificado de manera segura y adecuada. In turn, the structural design and dome-shaped configuration of the upper portion of the container 102, prevents the accumulation of product to dose inside improving communication between the interior thereof and the chamber of dosage, so, the entire product is dosed safely and properly.
