PACKING MATERIAL FILLING DEVICE

摘要

Provided is a packing material filling device which maintains the pressure of a filling fluid food in a tube at a positive pressure, easily pre-shapes by using a molding flap, can prevent the dropping to a negative pressure even if the pressure of the liquefied food pressure is lowered by fluctuations in the liquefied food pressure, and prevent the seeping in of materials in the external environment into the tube. A positive pressure holding means lessens the fluctuations in the pressure of the liquefied food in the tube below the pressure flange, prevents the lowering of the liquefied food pressure to a negative pressure, and maintains the liquefied food pressure at a positive pressure.
