Container with a synthetic lining impermeable to liquids and method of making

摘要

A container comprising a non-deformable shell under ordinary stresses made from at least two cooperating parts which together constitute said shell, said shell being lined internally with and thermoplastically fused with a lining made of a liquid-impermeable thermoplastic material and a method of making said container, comprising (a) introducing at least two cooperating parts which together constitute a non-deformable shell under ordinary stresses into molding tool members which each have a contour corresponding to at least a portion of the outer surface of each part of the shell, (b) bringing the parts together, (c) applying a substantially even film of thermoplastic material at an elevated temperature and in an at least plastic state to the inner surface of the parts to produce on the internal surface of the wall of the shell a lining, which is liquid-impermeable and thermoplastically fused to the shell when the container is at ambient temperature, and (d) removing the container from the molding tool members.
