Abstract
Plastic jerry cans are formed from a pair of injection-molded surface-stabilized, low warpage plastic shells having high diffusion tightness and low surface resistance to electrical conduction. A contiguous plastic inner wall is blow-molded from the inside of the shells and is fused onto the interior surface of the shells. The inner wall seals the shell halves together at the flat bottom of cone-shaped inward dips on the large side surfaces of the shells.
Claims14
A plastic jerry can comprising an outside wall which consists of a surface-stabilized low-warpage material of sufficiently high diffusion density and sufficiently low surface, skin effect resistance, which material is injected in the form of shells forming a portion of the shape of said jerry can, and
- a contiguous blow molded plastic wall sealed onto and around the interior surface of the shells.
A plastic jerry can for easily combustible liquids having a shape including large faces and end faces comprising
- an outside wall comprising two slender truncated cones forming a portion of the shape of the jerry can and comprised of a surface-stabilized, low warpage material of surface, skin effect resistance considerably below 10.sup.9 ohms,
- said cones having holes in spaced-apart truncated end-portions thereon,
- said cones projecting inward at the large faces of the jerry can,
- a wall of highly diffusion-tight, blow molded tube sealed onto and around the interior surface of the truncated cones and in the space between the spaced-apart end portions of the truncated cones, and
- rivet-like means through the holes in the truncated end portions for fastening the truncated cones to each other with the blow molded material in the space between them.
