A correction fluid dispenser comprising a body member (2) adapted to retain correction fluid, a barrel member (12) received by the body member (2), a core portion (24) extending axially of the body (2) and barrel (12) members, and tip seal member (34) disposed in a recess (28) in the core portion (24) and spring biased toward an orifice (38) in the barrel member (12) to block the orifice (38) and prevent flow of fluid therethrough when not in use. The tip seal member (34) being retractable against the spring bias to permit fluid flow through the orifice (38) when in use. The above arrangement requires a strong spring bias to block the orifice (38) when not in use. However, the strong spring bias is difficult to overcome when in use. Inadvertent actuation could also occur with the above structure. The solution to the above problem is to enable the body (2) and barrel (12) members to move the core portion (24) relative to the tip seal member (34) until contact, and thereby the tip seal member (34), into the orifice (38) in blocking, non-retractable position. |
