Abstract
Art instrument having a self-contained reservoir for storing and dispensing application liquid includes a reservoir body for containing the application liquid and a dispensing assembly that dispenses the application liquid from the reservoir. The dispensing assembly includes an applicator, a primary orifice restrictor including a channel, a movable actuating assembly that retains the applicator and the primary orifice restrictor and is movably connected to the reservoir body, and a secondary orifice restrictor arranged in an opening of the reservoir body and includes an initially closed channel. The instrument also includes a partly movable control mechanism that controls movement of the actuating assembly relative to the reservoir body. The control mechanism having a configuration in which it prevents opening of the closed channel and thereby prevents leakage of application liquid from the reservoir prior to manual activation by a user.
