Abstract

PURPOSE:To obtain a double vessel which enables foodstuffs to separate sufficiently from soup and make the environs of the foodstuffs into atomosphere superior in permeability, by a method wherein at the time of integration of an inner and outer vessels of the doudle vessel, an air gap is formed between bottom parts of both the vessels and a plurality of through holes are formed in the bottom of the inner vessel. CONSTITUTION:A head obtained by setting a large number of pins to a first sheet materials 41 formed of a foamable resin material which is in transit is receiprocated, and a large number of through holes 14 are formed in a part of the said matterial 41 becoming the bottom of a double vessel 100. Then a second material sheet 42 formed of a solid type resin material is heated to weld the said materials 42 to the first sh.et material 41. Then an air gap 30 is formed between an inner and outer vessels 10, 20 by accelerating suction of either the first sheet material 41 or the second sheet material 42 to be conveyed within a vacuum molding device 40 having a first and second molds 45, 46 at the time of vacuum molding. The first and second molds 45, 46 are stuck close to each other and flange parts of both the inner and outer vessels are welded together even if suction at the mold side has to be stopped.
