Abstract
A container for housing fluid material to be dispensed in incremental amounts. A conduit integrally formed with the container and in fluid-flow communication therewith serves to deliver material from the container upon generation of gaseous pressure within the body of the container above the physical level of the material stored therein. The container also includes a restricted filling port fitted with a closure cap. Interposed between the port and the body of the container, in coaxial disposition therewith, is a bellows assembly. The latter surmounts the container in fluid communication therewith, whereby application of manual or digital pressure downwardly upon the capped container effects physical compression of the bellows to force a volume-controlled and repetitively-rerproducible, incremental quantity of stored material from an open, exposed end of the fluid-delivery conduit for use. Withdrawal of compression forces applied to the bellows, and resultant responsive physical re-expansion of the bellows, effects, automatically, a vacuum-derived positive and forceful clearing of residual material from a lineal end sector of the product delivery conduit. Any dripping of material from the open end of the conduit is also obviated.
