Patent ID: 8360671

Claim:
An art instrument having a self-contained reservoir for storing and dispensing application liquid, comprising: a reservoir body for containing the application liquid, said reservoir body having an open end including an opening; a dispensing assembly that dispenses the application liquid from said reservoir, said dispensing assembly comprising: an applicator; a primary orifice restrictor including a channel; a movable actuating assembly that retains said applicator and said primary orifice restrictor, said actuating assembly being movably connected to said open end of said reservoir body; and a secondary orifice restrictor arranged in said opening of said reservoir body and including an interior channel and a closure that closes said channel; and a partly movable control mechanism that controls movement of said actuating assembly relative to said reservoir body, said control mechanism having a first configuration on said reservoir body in which said control mechanism allows said channel of said primary orifice restrictor to be in flow communication with said channel of said second orifice restrictor and a second configuration on said reservoir body in which said control mechanism prevents engagement of said primary orifice restrictor with said second orifice restrictor and thus opening of said closure of said channel of said secondary orifice restrictor to thereby maintain said channel of said secondary orifice restrictor in a closed state until manual movement of said control mechanism into said first configuration.
