Patent ID: 7040523

Claim:
An applicator device for abutment by or attachment to a reciprocating mechanism of a viscous fluid material printing machine, the applicator device being for applying a viscous fluid material to a surface therebeneath and comprising: a body having a through passage with an upper, fluid inlet extending along the body, a lower, fluid outlet extending along the body and pressure reduction means between the inlet and the outlet of the body for reducing the pressure of the fluid material; a sealing gasket or foil for peripherally sealing the outlet of the body against a stencil on being pressed thereagainst; an elongate, horizontally-extending reservoir for fluid material formed with or detachably mounted on an upper side of the body and being in fluid communication with the inlet of the body; and a displaceable piston extending in the reservoir for displacing fluid material out of the reservoir into the inlet of the body and, via the pressure reduction means, to the outlet of the body, with the piston being actuable from above by the reciprocating mechanism of the printing machine so as to be displaceable thereby and the applicator device being without and not requiring any other separate motive power source or pipe ducting means for such displacement.
