摘要:
The present invention relates to a packing method and an apparatuses implementing said method in which a material is packed into a container by an air tapping process in which the air-pressure state of the space comprising a container and a space part connected with said container, which space being loaded with the material, is switched several times from a low air-pressure state to a high air-pressure state alternately, while keeping said low air-pressure state equal to or higher than the atmospheric pressure existing outside said space, thereby preventing the material from getting blown up by the inflow of the atmospheric air outside the container and packing a material into said container homogeneously.
