Abstract: This invention relates to containers for liquified gases, of the kind which comprise an inner container intended to hold the liquified gas which consists of a container body and an elongated neck, and an outer shell spaced away from the said inner container which forms with the latter an evacuated insulating space packed with material made up of successive superimposed layers of materials which are alternately conductive and insulating, marginal portions of the said layers of conductive material being in individual thermal contact, along annular areas spaced above one another, with the neck of the inner container, which extends to the said outer shell. According to the invention, the neck of the inner container is made from a plastics material, the thermal contact between the screening layers of conductive material and the neck being ensured by simple free contact under pressure. The inner container may be made from resin or glass, either of which may be reinforced by fibres.
