摘要

Apparatus for dispensing liquid preparations which comprises a container having demountable upper and lower container parts, the upper container part of which has a pressurized-fluid inlet connected by a flexible connecting line to a source of pressurized fluid and a vent, a flexible diaphragm located in the container so as to provide an expandable and contractable pressurized-fluid chamber and an expandable and contractable preparation chamber in the container, a charging and discharging orifice in the lower container part, and a flexible connecting line connecting that orifice with a point at which fluid is discharged. The container is mounted for rotation on a horizontal axis for allowing rotation of the container from a position in which the charging and discharging orifice in the lower container part is uppermost for filling and lowermost for discharge. The vent is so located with reference to the charging orifice that a back pressure is maintained in the pressurized-fluid container part sufficient to prevent collapse of the diaphragm faster than liquid preparation is fed in through the charging orifice.
