An applicator () includes a main body (), a parallel crank (), and a lever (). The parallel crank () includes a first crank bar () and a second crank bar (). The first crank bar () and the second crank bar () each have one end portion swingably coupled to the main body (). To the lever (), another end portion of the first crank bar () and another end portion of the second crank bar () are each swingably coupled. The second crank bar () covers at least a part of side surfaces on both sides of the first crank bar () in an axial direction of a pin () as a rotation axis of the first crank bar () with respect to the main body () in a sandwiching manner.

Applicator

To prevent accidental discharge from a cartridge, a dispenser for the dental viscous material comprises a guide shafthaving a cylindrical partat a front end thereof, a guide memberhaving a large diameter partand a small diameter parton the rear side of the cylindrical part, and a knob for rotating the guide shaftat a rear end, a slide blockhaving a release plate, and piston shafts, a housinghaving pressing springs, which press piston shafts, and a lever main bodyhaving a lever partrotatable by a predetermined angle from a position in parallel to the housingand a pressing pieceprojected under the front side of the lever part, to constitute a mechanism of switching of discharge state and discharge release state.

Dispenser for dental viscous material

A dispenser for dental viscous material including a box-shaped handle provided with a cartridge-mounting portion for mounting a cartridge containing a dental viscous material. A guide shaft is supported in the front and back direction in a cavity of the box-shaped handle, at a preset position of which is provided a lever-engaging portion. A lever is provided in the box-shaped handle via a lever shaft, one end of which is engaged with the lever-engaging portion of the guide shaft and the other end of which is positioned outside the box-shaped handle. An elastic member is engaged with the box-shaped handle and the guide shaft or the lever so as to return the guide shaft to an initial position.
