Abstract: A method of fabricating plastic products with an integrated Lenticular lens material that thermally protects the ink layer and outer lens surfaces of the Lenticular insert. A Lenticular lens material is provided with a Lenticular lens layer with an outer surface of optical ridges and an ink layer bonded to a transparent lens layer. A thermal protective substrate comprising opaque flexographic ink is applied to the ink layer. The application of the thermal protective substrate is completed using a coating unit of a lithographic press. A Lenticular insert is formed from the coated Lenticular lens material and the insert is positioned within a mold cavity. The object is formed by inserting a liquid plastic charge into the mold cavity. The thermal protective substrate insulates the ink layer. Concurrently, the portion of the mold adjacent the insert is cooled to a temperature below the deformation temperature of the optical ridges.

Abstract: This disclosure relates to a plastic container having a separate cup-shaped base telescopically assembled on its bottom to provide stability so that the container can stand upright, and to a method of assembling the base on the container. The container includes a tubular side wall, such as in blow-molded bottles, and a generally convex bottom which is integrally interconnected to the side wall by an arcuate annular heel. A peripheral groove is provided on the outer surface of the container adjacent the heel to receive a radially inwardly directed peripheral bead or lip on the upper end of the base, forming an essentially water-tight seal. One or more longitudinal surface indentations are formed on the outer surface of the container beneath the circumferential groove, to allow the escape of air between the base and the container bottom during their telescopic assembly.
