Dosing device which can be placed on various containers

摘要

A dosing device for containers comprising a unit having an inner part (1) made of a flexible elastic material, placed in a cap (2) made of a rigid material. The unit either fits onto a container (3) having an assembling part whose shape is adapted to receive the unit, or the unit can be integral with the container. The elasticity of the part (1), and its form which is associated with the form of the cap (2), produces and discharges a dose when pressure is exerted on the cap (2), without allowing air from outside the container to come in contact with the contents (31) of the container (3).
