PURPOSE:To make it possible to pour foaming resin in an inner boot under high pressure by a method wherein two-pack type forming resin is mixed and agitated in a metal can having a large strength to pressure. CONSTITUTION:By shaking a metal can vertically after the lid 9 of an inner can 4 is unfastened by pushing a slide tube 10 downwards, a second liquid 7 in the inner can 4 and a first liquid 6 in an outer can 3 are mixed with each other so as to start foaming. After that, the pouring hose C of an inner boot B is mounted through a lever 20 to the tip of a nozzle 17. Further, after the pressure in said metal can 1 rises high enough due to foaming, the lever 20 is depressed, resulting in tilting the nozzle 17 so as to form a gap between the lower end opening of a packing 16 and the choking plate 18 of the nozzle 17, resulting in jetting foaming resin in the metal can 1 through the slide tube 10 and said gap from the nozzle 17 so as to pour the foaming resin through the pouring hose C into the inner boot B. |
