Lightweight container.

摘要

A novel pressure holding container (1) formed of thin sheet metal of the order of between 10 and 4 mils wherein the container has a bottom portion (2) and a top portion (3), the bottom portion having a body and an integral bottom, and in one embodiment having a necked-in upper end of the body which tigthly fits into a lip portion (14) of the lower end of the top portion and is adhesively bonded thereto and wherein the upper portion (16) of the top portion has a toroconical shape which under pressure wants to expand it into a spherical shape and thus trhough beam loading on the lip portion imposes compressive stresses theron and holds in compression the adhesive (32) which is interposed between the lip and the annulus of the necked, in portion of the body which is loaded in tension by the internal pressure in the container.
