Abstract

PURPOSE:To keep the amount of the sterilizing liquid in a sterilizing liquid tank constant and to sufficiently and certainly bring a strip of packing material into contact with the sterilizing liquid, by providing a flow rate control hole to the side wall of the sterilizing liquid tank and performing the insertion and detaching operation of a truncated cone-shaped plug body to regulate the liquid amount in the tank. CONSTITUTION:Sterilizing liquid tanks 13a, 13b are opened at the upper and bottom parts thereof and form sterilizing liquid flow channels from the upper opening parts thereof to the bottom opening parts thereof and have linear slots 13a', 13b' capable of permitting a packaging material 19 to be sterilized to pass formed to the bottom opening thereof while flow rate control holes 38 are provided to one sides of said tanks by drilling and conical plug bodies 41 having a taper surface are provided to said holes 38 in a freely inserting and detaching state so as to make is possible to adjust the gaps with the flow rate control holes. A sterilizing liquid tank 12 is provided below the sterilizing liquid tanks to store the sterilizing liquids falling from the sterilizing liquid tanks. A pipe mechanism 16 communicates with the sterilizing liquid tank at one end thereof and the other end thereof is communicates with the sterilizing liquid supply nozzles 15 positioned above the sterilizing liquid tanks. A drive mechanism such as rollers 18, 20, 21 permits a strip of packing material to pass between the upper and bottom parts of the sterilizing liquid tanks.
