| Abstract: |
A high-relief, resiliently flexible composite molded plastic product (21). The product (21) includes a relatively rigid injection molded core member (22) having a pair of oppositely facing core shoulders (26,27), and a plastic sleeve member (23) with sleeve shoulders (36,37) interengaged with the core shoulders (26,27). The sleeve member (23) is rotationally cast or molded from a plastisol dispersion having emulsion grade polyvinylchloride and suspension grade polyvinylchloride in a ratio of at least 3:1, and preferably 5:1, to produce substantial flexibility and to enable high-relief design features (46) to be molded into the sleeve member (23).

First Claim:
Show all 18 claims |
What is claimed is:
1. A high strength and impact resistant composite molded plastic product for use as a container for liquid comprising:
- a rigid core member having a sleeve-receiving end and a pair of oppositely facing, axially spaced apart core shoulders formed therein each having a shoulder radial depth dimension extending radially outward, relative a core longitudinal axis, from a core outer surface to a respective shoulder outer surface; and
- a resiliently flexible plastic sleeve member having a pair of oppositely facing sleeve shoulders formed for interengagement with said core shoulders over said shoulder radial depth dimension sufficient to secure and mount said sleeve member on said core member, said sleeve member being rotationally cast from a plastisol dispersion of emulsion grade polyvinylchloride and suspension grade polyvinylchloride in a ratio of at least 3 to 1 by weight to provide a set sleeve member of said ratio with a resilient elasticity sufficient to enable heat-free mounting of said sleeve member onto said core member over said sleeve-receiving end until said core shoulders and said sleeve shoulders are interengaged, an inner surface of said sleeve member intermediate said sleeve shoulders being outwardly spaced from said core outer surface over a substantial area of the sleeve inner surface to provide an insulatory cavity between said inner surface and said outer surface, and said sleeve member including at least one prominent molded design feature having a feature radial depth dimension extending radially outward, relative the sleeve longitudinal axis, from the core outer surface to a distal surface of said prominent feature at least four times said shoulder radial depth dimension.
