VESSEL MADE OF COMPOSITION MATERIAL Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: vessel has plastic shell, flanges mounted in the pole openings in the shell, and lid set in one of the pole flanges. The lid is concave inward and bears on the inner side of the pole flange. The butt between the pole flange and lid is made to provide the radius of the circumference formed by intersection of the middle surface of the lid and surface of the bearing part of the flange to be larger than that of the pole opening in the plastic shell. The thickness of the pole flange should be at least 1.5-2 mm, which is sufficient for the formation of the plastic shell. The loading acts on the developed bearing surface of the lid which is mating to the inner surface of the pole flange.

EFFECT: decreased weight of vessel.
