Fuente: WIPO "hemp" 666,181. Cold and heat retaining vessels. HEMP & CO., Inc. June 7, 1949 [March 28, 1949], No. 15133/49. Class 64(ii) An insulating container has a jacket in which an inner vessel or liner is suspended by means of a flange formed thereon (or on the jacket) and engaged between a pair of ring gaskets which seal the space between the liner and the jacket and are carried by the jacket (or liner). An inturned flange 18 at the mouth of a jacket 11 is held between gaskets 19, 20, e.g. of rubber, which are gripped by a shoulder 7 and a curled-over flange 9 formed on a liner neck 5 to give a tight seal. The flange 18 of the metal jacket 11 defines a mouth which enables the upper part of the two-part jacket to be placed over the liner flange 9 before this flange is embedded in the top gasket 19. The liner is coated with vitreous enamel and surrounded with insulating material.
