Title (EN) CONTAMINATION-RESISTANT DISPENSING AND METERING DEVICE
(FR) SYSTEME D'APPORT ET DE DOSAGE A L'EPREUVE DE LA CONTAMINATION
Abstract:
(EN) This invention relates to the field of liquid dispensing and metering devices that dispense a solution in drop form and protects the solution from contamination. In applications where contamination and proper dosage is a concern, the prior art discloses dispensers related both to the use of anti-bacterial agents added to the solution to prevent contamination and the use of a single dose device. Both present problems, as the addition of the agent causes allergic reactions in some users, while the single dose device is inconvenient to the frequent user. Prior art dispensers also do not permit control of metering for proper dosage. This invention solves these problems by providing a filter in the dropper portion of the device to prevent contamination of the solution. The device includes a dropper (2) having an outlet (3) and filter (4). The filter is a composite consisting of a liquophilic component (5) and a liquophobic component (6).
(FR) Cette invention concerne des systèmes d'apport et de dosage permettant de distribuer une solution sous forme de gouttelettes et protégeant ladite solution de toute contamination. Dans des utilisations pour lesquelles la contamination et le dosage approprié sont un problème majeur, l'art antérieur prévoyait des distributeurs utilisant des agents antibactériens ajoutés à la solution pour empêcher la contamination et employant également un système de doseur unique. Ces deux systèmes présentent des problèmes, étant donné que l'ajout de l'agent antibactérien provoque des réactions allergiques chez certains utilisateurs, et que le doseur unique ne convient pas à l'utilisateur assidu. En outre, les distributeurs de l'art antérieur ne permettent pas de régler le dosage pour obtenir la dose appropriée. Cette invention résout ces problèmes en prévoyant un filtre dans la partie du système où se forment les gouttes, afin d'éviter la contamination de la solution. Le système comprend un système de formation de gouttes (2) présentant un orifice de sortie (3) et un filtre (4). Ledit filtre est un composite constitué d'un composant liquophile (5) et d'un composant liquophobe (6).
