ABSTRACT:
An dispenser characterized by provision for use of a replaceable needle and a prefilled cartridge.
The dispenser comprises an elongated body separable into two body sections, with the front end section adapted to contain a prefilled cartridge and with provision at the front end for mounting a needle removably thereon.
The back end section contains the operating mechanism shown by FIG. 10 to convert the longitudinal movement of a pushable element into unidirectionally rotary movement, then into longitudinal movement of a piston rod that acts to expel fluid through the needle.
A multipurpose cap is protective of the needle end when mounted on the front end, and is an operating member when mounted on the rear end, as is illustrated by FIGS. 1 and 2.
