ABSTRACT:
A fluid dispenser according to the present invention has a tubular body having therein a fluid chamber, a pusher for pushing the fluid, and a feed mechanism for progressively advancing the pusher. The feed mechanism has a slider and an actuator for advancing the pusher so that a suitable amount of the fluid in the fluid chamber of the tubular body is fed to an outlet of the dispenser. The outlet may be in the form of a nib when the dispenser is in the form of a writing pen.
In a preferred embodiment of the invention, the feed mechanism has a nut fixed within the tubular body, a threaded rod threadedly engaged with the nut, a rotary member slidably mounted on the threaded rod and spring biased rearwardly towards the actuator, a slider for rotating the rotary member, and a guide device for guiding the rotary member and the slider. The guide device has grooves on the inner surface of the tubular body.
