    • The present invention provides a small and inexpensive gas mixing/supplying device for introducing a gas into a high-viscosity material, by use of which a high-viscosity material can be directly supplied from a container such as a cartridge.
      The present invention comprises:
      a step of effecting a first suction stroke in which the piston 25 is moved in the cylinder 27 so as to generate a suction condition in the cylinder 27;
      a step of supplying a high-viscosity material to the cylinder, using a suction force in the cylinder generated in said first suction stroke;
      a step of stopping the piston after said first suction stroke;
      a step of effecting a second suction stroke in which the piston is moved in the cylinder after the supply of the high-viscosity material;
      a step of supplying a gas to the cylinder, using a suction force in the cylinder generated in the second suction stroke;
      a step of effecting a pressurizing stroke in which the piston is moved in the cylinder after completion of the supply of the gas, to thereby pressurize the high-viscosity material and the gas; and
      a step of effecting a discharge stroke in which the high-viscosity material and the gas are discharged into a conduit. Then, the high-viscosity material is foamed under atmospheric pressure.
    • 本发明提供了一种用于将气体引入高粘度材料中的小而便宜的气体混合/供给装置,通过使用该气体混合/供给装置可以从诸如筒的容器直接供应高粘度材料。 本发明包括:实现第一吸入行程的步骤,其中活塞25在气缸27中移动,以在气缸27中产生吸入状态; 使用在所述第一吸入行程中产生的所述气缸中的吸力将高粘度材料供应到所述气缸的步骤; 在所述第一抽吸行程之后停止所述活塞的步骤; 在提供高粘度材料之后进行活塞在气缸中移动的第二吸入行程的步骤; 使用在第二吸入冲程中产生的气缸中的吸力将气体供应到气缸的步骤; 在完成气体供给之后进行活塞在气缸中移动的加压冲程的步骤,从而对高粘度材料和气体加压; 以及将高粘度材料和气体排出到导管中的排出行程的步骤。 然后,高粘度材料在大气压下发泡。
