Description
DISPOSITIVO DISPENSADOR DE LÍQUIDOS CON MECANISMO ANTIRRETORNO DE GOTA Y FILTRO DE AIRE LIQUID DISPENSING DEVICE WITH ANTI-DROP RETURN MECHANISM AND AIR FILTER
CAMPO TÉCNICO TECHNICAL FIELD
La presente invención se enmarca en el campo técnico de los dispensadores de productos oftálmicos, específicamente se da a conocer un dispositivo dispensador de gotas multidosis con mecanismo antirretorno de gota, difusor de aire para un uso libre de preservantes. The present invention is part of the technical field of ophthalmic product dispensers, specifically a multi-dose drop dispensing device with an anti-drop mechanism, air diffuser for preservative-free use is disclosed.
ESTADO DE LA TÉCNICA STATE OF THE ART
En el estado de la técnica existen algunas tecnologías relacionadas con goteros multidosis sin preservantes, con mecanismos antirretorno de gota y sistema de purificación del aire, ejemplos de este tipo de tecnología son los documentos de patente US9345616B2 o US9238532B2 de la empresa Nemera la Verpilliere SAS o el documento US9833356B2 de la empresa Aptar Radolfzell GmbH, los cuales involucran válvulas con resortes o válvulas de membrana. Sin embargo, estos antecedentes tienen la desventaja de que su fabricación involucra el acople de una gran cantidad de piezas de dimensiones muy complejas que no permiten su elaboración bajo un concepto de uso de tecnologías de fabricación simples y rápidas (por ejemplo, a través de la tecnología convencional de Blow/fill/seal), asimismo, tienen la desventaja de que sus picos son achatados y gruesos lo que no permite el fácil y preciso guiado en la aplicación de la gota sobre el usuario. Otra desventaja de estos dispositivos es que el filtro mismo para la purificación del aire que ingresa al sistema es ancho, grueso o bien de un gran diámetro con respecto al diámetro de la boca del frasco. Ninguna de las tecnologías del estado de la técnica permite el ensamblaje en una sola operación, ni especifican una solución al problema del ensamblaje de las piezas sin necesidad de una alineación rotacional para que el flujo del aire de compensación entre sin problemas al interior del dispositivo. Adicionalmente, los dispositivos dispensadores del
estado de la técnica no comprenden un capuchón el cual tenga la suficiente extensión para subir y proteger el agujero de retorno de aire de la carcasa superior. In the state of the art there are some technologies related to multi-dose droppers without preservatives, with anti-drop mechanisms and an air purification system, examples of this type of technology are patent documents US9345616B2 or US9238532B2 from the company Nemera la Verpilliere SAS or US9833356B2 from Aptar Radolfzell GmbH, which involve spring valves or diaphragm valves. However, these antecedents have the disadvantage that their manufacture involves the coupling of a large number of pieces of very complex dimensions that do not allow their elaboration under a concept of using simple and fast manufacturing technologies (for example, through the conventional Blow / fill / seal technology), likewise, have the disadvantage that their peaks are flattened and thick, which does not allow easy and precise guidance in the application of the drop on the user. Another disadvantage of these devices is that the filter itself for the purification of the air entering the system is wide, thick or of a large diameter with respect to the diameter of the mouth of the bottle. None of the technologies of the state of the art allow assembly in a single operation, nor do they specify a solution to the problem of assembling the parts without the need for rotational alignment so that the flow of compensation air enters the interior of the device without problems. Additionally, the dispensing devices of the State of the art do not comprise a cap which has sufficient extension to raise and protect the air return hole of the upper casing.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
Con el objetivo de solucionar los problemas anteriormente mencionados del estado de la técnica, se desarrolló la presente invención la cual se refiere a un dispositivo dispensador de líquidos el cual comprende: un primer elemento al cual se le ha denominado como “cuerpo de circulación de flujos”, este elemento a su vez incluye un primer hundimiento anular en una superficie lateral exterior; al menos un agujero pasante ubicado en el primer hundimiento anular adecuado para el flujo de aire entre la parte externa con la parte interna del cuerpo de circulación de flujos; un difusor o membrana de silicona dispuesto en la parte interna del cuerpo de circulación y en comunicación directa con el al menos un agujero pasante de filtración de aire, donde, por este agujero pasante se conduce el aire para compensar la salida del líquido dispensado al usar el presente dispositivo, filtrando el aire antes de que tenga contacto con el líquido al interior del envase; un segundo hundimiento anular (medios adherentes o elementos de fijación para sostener un anillo de sellado) ubicado debajo del primer hundimiento anular en una superficie lateral exterior del cuerpo de circulación; un tercer hundimiento anular (medios adherentes o elementos de fijación que sostienen un anillo de sellado) dispuesto en una superficie superior del cuerpo de circulación; unos agujeros pasantes en la superficie superior del cuerpo de circulación, donde por estos agujeros pasa en primer lugar el líquido al interior del dispensador cuando el frasco es presionado; un soporte (asiento) de válvula con canales a lo largo dispuesto en la superficie superior del cuerpo de circulación de flujos; un anillo de sellado inferior dispuesto en el segundo hundimiento anular, un anillo de sellado superior dispuesto en el tercer hundimiento anular superior. De esta forma, entre los anillos de sellado se aísla la porción del cuerpo de circulación por donde ingresa el aire de compensación a ser filtrado por el sistema;
asimismo, el anillo de sellado superior tiene la función de evitar fugas del líquido cuando el frasco es presionado y el líquido circula a través del cuerpo. El anillo de sellado superior también sirve para ejercer una contrapresión y permitir un adecuado ensamble, funciona como un “resorte” que permite que el conjunto quede enganchado, haciendo “click” al momento del ensamble. With the aim of solving the aforementioned problems of the state of the art, the present invention was developed which refers to a liquid dispensing device which comprises: a first element which has been called "flow circulation body ", This element in turn includes a first annular recess in an outer lateral surface; at least one through hole located in the first annular recess suitable for air flow between the external part with the internal part of the flow circulation body; a silicone diffuser or membrane arranged in the internal part of the circulation body and in direct communication with the at least one through hole for air filtration, where, through this through hole the air is conducted to compensate the exit of the dispensed liquid when using the present device, filtering the air before it comes into contact with the liquid inside the container; a second annular recess (adhering means or fastening elements to hold a sealing ring) located below the first annular recess on an outer side surface of the circulation body; a third annular recess (adhering means or fixing elements supporting a sealing ring) arranged on an upper surface of the circulation body; through holes in the upper surface of the circulation body, where the liquid first passes through these holes into the dispenser when the bottle is pressed; a valve support (seat) with channels along the length provided on the upper surface of the flow circulation body; a lower sealing ring arranged in the second annular recess, an upper sealing ring arranged in the third upper annular recess. In this way, between the sealing rings the portion of the circulation body is isolated through which the compensation air to be filtered by the system enters; Also, the upper sealing ring has the function of preventing leakage of the liquid when the bottle is pressed and the liquid circulates through the body. The upper sealing ring also serves to exert a counter pressure and allow an adequate assembly, it works as a “spring” that allows the assembly to be hooked, making “click” at the moment of assembly.
La invención además incluye una válvula de membrana o cuerpo de válvula que cubre y rodea al soporte de válvula con una abertura de formación de gotas en una punta del soporte de válvula; preferiblemente y visto desde un corte longitudinal, la parte inferior de la válvula de membrana tiene una terminación en punta tipo cuña. Cuando se presiona el frasco, la presión hace que el líquido del frasco circule entre el soporte de válvula y el cuerpo de válvula; y, cuando se deja de presionar el frasco, el espacio entre el soporte de válvula y el cuerpo de válvula se cierra. En otra forma preferente, esta válvula de membrana tiene una terminación superior que se va estrechando, dejando un pequeño espacio abierto (un espacio entre 1 mm y 1.8 mm de diámetro, preferiblemente 1.4 mm) y a continuación extremos internos que se van ensanchando en forma de un cono invertido para la formación de la gota. The invention further includes a membrane valve or valve body that covers and surrounds the valve holder with a droplet opening at a tip of the valve holder; preferably and viewed from a longitudinal section, the bottom of the diaphragm valve has a wedge-like tip termination. When the bottle is pressed, the pressure causes the liquid in the bottle to circulate between the valve holder and the valve body; and, when the bottle is released, the space between the valve holder and the valve body closes. In another preferred form, this diaphragm valve has an upper termination that tapers, leaving a small open space (a space between 1 mm and 1.8 mm in diameter, preferably 1.4 mm) and then internal ends that widen in the shape of a an inverted cone for droplet formation.
Otro elemento de la presente invención es una carcasa superior o pico que cubre al cuerpo de circulación de flujos y se acoplan a presión entre sí, con un agujero pasante dispuesto a la altura del primer hundimiento anular; y, una tapa con una protuberancia central para absorber gotas residuales y evaporarlas a través de un orificio pasante de ventilación ubicado en la parte superior de la tapa. Another element of the present invention is an upper casing or spout that covers the body of flow circulation and is coupled under pressure to each other, with a through hole arranged at the height of the first annular recess; and, a lid with a central protrusion to absorb residual drops and evaporate them through a through-vent hole located in the upper part of the lid.

- Tiene un número muy reducido de piezas, comparado a los demás antecedentes del estado de la técnica que requieren del ensamblaje de varios
componentes para lograr el objetivo de proporcionar un dispensador para frascos multigotas con mecanismo de filtrado de aire con sistema de gotas antirretorno y libre de preservativos. - It has a very reduced number of pieces, compared to the other antecedents of the state of the art that require the assembly of several components to achieve the goal of providing a multi-drop bottle dispenser with air filter mechanism with non-return drop system and free of condoms.
- Permite un rápido y fácil ensamblaje de sus componentes, puesto que al menos 3 piezas se pueden ensamblar en una sola operación empleando tecnologías de inyección de plástico de doble disparo (double-shot) y multi- material en una máquina inyectora de última generación y con capacidad de inyectar silicona liquida ( LSR ), la forma como se han diseñado los elementos de lo propuesto permite el rápido y fácil acople de las piezas a través de protuberancias o muescas de enganche y mecanismos de presión (sin necesidad de roscas). - It allows a quick and easy assembly of its components, since at least 3 pieces can be assembled in a single operation using double-shot and multi-material plastic injection technologies in a state-of-the-art injection machine and With the capacity to inject liquid silicone (LSR), the way in which the elements have been designed allows the quick and easy coupling of the pieces through protrusions or hooking notches and pressure mechanisms (without the need for threads).
- No requiere de la alineación por rotación del cuerpo de circulación de flujos con la carcasa superior para crear una vía de comunicación y entrada de aire al sistema, simplemente basta con el ensamblaje directo a presión, uno sobre otro. - It does not require the rotation alignment of the flow circulation body with the upper casing to create a communication path and air inlet to the system, the direct assembly under pressure, one on top of the other, is simply enough.
- Se ha superado un prejuicio técnico que solía existir en el estado de la técnico, donde se creía que el difusor o membrana de filtración de aire debería ser grueso y largo, o de un gran diámetro, para facilitar la filtración del aire; sin embargo, se ha encontrado que basta con una membrana plana y de un diámetro relativamente pequeño (con un área entre 5mm2 y 20 mm2) se logra purificar el aire a niveles adecuados para que funcione correctamente la invención, superando así el prejuicio técnico de un filtro grueso, gran o de gran diámetro. - A technical prejudice that used to exist in the state of the art has been overcome, where it was believed that the diffuser or air filtration membrane should be thick and long, or of a large diameter, to facilitate air filtration; However, it has been found that a flat membrane with a relatively small diameter (with an area between 5mm 2 and 20mm 2 ) is sufficient to purify the air at adequate levels for the invention to function correctly, thus overcoming technical prejudice. of a coarse, large or large diameter filter.
El aparato dispensador de la presente invención es más pequeño comparado con los goteros oftálmicos de multidosis sin preservantes de las tecnologías antecedentes propuestas por Nemera o Aptar. The dispensing apparatus of the present invention is smaller compared to the multi-dose ophthalmic droppers without preservatives of the background technologies proposed by Nemera or Aptar.
