Fluid dispenser

A fluid dispenser comprising:

• a tubular body having an outlet nib at one end thereof, said tubular body having a liquid chamber therein for containing a liquid, said liquid chamber being connected to said outlet nib so that the liquid can be fed to said outlet nib when pressure is applied to liquid in said liquid chamber;
• a pushing device longitudinally slidably mounted within said tubular body and having means in said liquid chamber for applying pressure to the liquid in said liquid chamber when said pushing device is moved toward said outlet nib;
• feed means connected to said pushing device for progressively advancing said pushing device toward said outlet nib, said feed means having:
• a nut rotatably mounted within said tubular body at a longitudinally filed position therein,
• a threaded rod non-rotatably and longitudinally slidably mounted in said tubular body and threadedly engaged with said nut,
• a rotary means longitudinally slidable relative to said nut and engaged with said nut for rotating said nut when said rotary member is rotated,
• a slider in facewise abutment with said rotary member for rotating said rotary member when said slider is moved longitudinally toward said outlet nib, and guide means on the inner wall of said tubular body for defining a plurality of grooves in which said slider is engaged for guiding said slider;
• and
• an actuation device connected to said feed means for moving said slider when said actuation device is actuated, whereby when said actuation device is actuated, said rotary member is rotated to rotate said nut through a certain angle to advance said threaded rod, and said pushing device is progressively moved forward, thereby supplying liquid in said liquid chamber to said outlet nib.

• a pushing device longitudinaly slidably mounted within said tubular body and having means in said liquid chamber for applying pressure to the liquid in said liquid chamber when said pushing device is moved toward said outlet nib;
• feed means connected to said pushing device for progressively advancing said pushing device toward said outlet nib, said feed means having:
• a threaded rod threadedly engaged with said pushing device and rotatably mounted within said tubular body,
• a rotary member,
• a spring connected between said threaded rod and said rotary member for transmitting the rotation of said rotary member to said threaded rod,
• a slider in facewise abutment with said rotary member for rotating said rotary member when said slider is moved longitudinally toward said outer nib,
• guide means on the inner wall of said tubular body for defining a plurality of grooves in which said slider is engaged for guiding said slider;
• and
• an actuation device connected to said feed means for moving said slider when said actuation device is, whereby when said actuation device is actuated, said rotary member is rotated to rotate said threaded rod through a certain angle to advance said pushing device progressively forward, thereby supplying liquid in said liquid chamber to said outlet nib.

• a threaded rod non-rotatably and longitudinally slidably mounted within said tubular body,
• a tubular cam body having a tubular cam on the outer surface thereof, said tubular cam body being threadedly engaged with said threaded rod and rotatably mounted at a longitudinally fixed position within said tubular body, and
• a slider engaged with said tubular cam for rotating said tubular cam when said slider is moved toward said outlet nib, said slider being spring-biased in a direction away from said outlet nib;
• and
• an actuation device connected to said feed means for moving said slider when said actuation device is actuated, whereby when said actuation device is actuated, said tubular cam is rotated to advance said threaded rod and said pushing device is progressively moved forward thereby supplying liquid in said liquid chamber to said outlet nib.
