Title:
METHOD OF FORMING DENTAL RESTORATIVE MATERIAL PACKAGING
Document Type and Number:
WIPO Patent Application WO2005032395
Kind Code:
A3
Abstract:
A method of forming a capsule assembly which includes radiation-reactive dental restorative material includes exposing selected portions of an exterior surface of the container to laser generated radiation at an energy level sufficient to create indicia on the exterior surface, with the indicia having a sufficient contrast relative to the exterior surface to enable readily visual human and/or optical machine-readable detection of the indicia. The indicia identify characteristics of the radiation-reactive dental restorative material in the container, the container is formed from a laser-enhanced (LE) polymer which is inert relative to the radiation-reactive dental restorative material within the container. The ability of the container to dispense the radiation-reactive dental restorative material under pressure is not adversely affected by the exposure of the container to laser generated radiation when creating the indicia on the exterior surface of the container. Optionally, the exposure of the laser-enhanced (LE) polymer to laser generated radiation is done at an energy level sufficient to create one or more raised protrusions on the container, useful for engaging a resilient cap adjacent an orifice on the container.
