Stereoscopic decoration for cosmetic containers - utilises polished grain effect of cast plastic embedded in transparent cover

摘要

The transparent plastic cover is made in two sections with a horizontal joint. The undersurface of the upper part is hollowed out to form the required pattern which includes local bosses or ribs. Synthetic resin is poured into the space between the two sections and allowed to harden. The upper section is the removed and the ribs and bosses are cut away and the surface of the resin is polished so that a patter nis formed on the surface by the flow lines. When light shines on the cover the different angles of reflection of the different flow lines of the resin produce a stereoscopic effect.
