<p>An apparatus for dispensing liquid or pasty substances to gelatin capsules and the like, in particular for dispensing pharmaceutical products thereto. In order to maintain the substance to be dispensed in relative motion to prevent deleterious thickening, the apparatus includes a reciprocating dispensing control plunger which periodically enters a capsule or container to be filled. If no container is present and no dispensing is to take place, the control plunger retreats into a position wherein a separate metering piston continues to transport the material but returns it to a storage container via a conrol channel in the control plunger.</p> |
