Title:
APPARATUS AND METHOD FOR HEATING A POLYMERIZABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO2001074572
Kind Code:
A3
Abstract:
A system for dispensing a heated polymerizable lens forming composition comprising: a heating apparatus body (1500), the heating apparatus body being configured to hold the lens forming composition, the heating apparatus body comprising an opening for receiving a fluid container and an outlet; a heating system positioned within the heating apparatus body for heating the lens forming composition; and a valve (1520) positioned proximate the outlet, wherein the valve comprises an elongated member, wherein the elongated member is positionable within the outlet in a closed position, wherein the elongated member in the closed position inhibits flow of the lens forming composition through the outlet, and wherein the elongated member in an open position allows flow of the lens forming composition flows through the outlet during use; and a fluid container (1560) configured to hold a lensforming composition, the fluid container comprising: a fluid container body and a cap, wherein the cap comprises a fluid control member and an elastic member, wherein the elastic member is coupled to the fluid control membersuch that the elastic member exerts a force on the fluid control member suchthe fluid control member is forced against a top inner surface of the cap; wherein the fluid container is insertable into the opening of the heating apparatus, and wherein insertion of the fluid container into the opening causes the fluid control member to be moved to a position such that the lens forming composition flows from the fluid container into the heating apparatus body.
