Multidose dispenser for sterile liquid preparations

A dispenser for liquid preparations without preservatives, comprising a container body (1), a dropper assembly (2), and a closure capsule (3) suitable to be coupled with said dropper assembly (2), wherein the dropper assembly (2), in turn, comprises a closure element (4) for the container body (1) ending with a rigid dropper nozzle (5) provided with one or more transversal passage ports (8), communicating with the interior of said container body covered with a resiliently deformable tubular sleeve (9), cooperating with said ports (8) for intercepting a liquid preparation contained in said dispenser, characterized in that the said dropper nozzle (5) comprises at least two portions to axially subsequent portions having different conicity:

• a first portion with smaller conicity (6) making out the distal end of said dropper nozzle (5) and a second portion with grater conicity (7) on which said two or more ports (8) are provided, and in that said closure capsule comprises an internal projection (21) that comes into contact, when the capsule is closed, with said resiliently deformable tubular sleeve (9) at a position corresponding to the second portion of the dropper nozzle (5) with grater conicity (7), thereby blocking the possible passage of the liquid preparation through the said two or more ports (8).
