Abstract (en)
[origin: EP0862890A1] A novel unit doses powder with solvent. It includes a powder supply container (1) and a dosing opening which releases powder from the container. A unit (4, 5) supplies solvent, flushing the powder out, through the opening. In this new design, the dosing opening contains a sieve (3). Although the sieve is perforated, the perforations are at such an angle, that no opening is visible through the sieve, when observing perpendicularly to its plane. The underside of the sieve is sprayed with solvent. Preferable the sieve is a plastic plate with openings. The plate is Teflon (RTM) or polyvinyl chloride.
