The hydrogen peroxide gas supplying apparatus to be sterilized by the method of the invention comprises a hydrogen peroxide gas transport air pipe extending from an air source to the location of the article to be sterilized by way of a closed gasifying tank having a heater incorporated therein, and a microorganism removing filter provided on the air pipe and positioned upstream from the gasifying tank. The apparatus is sterilized by supplying an aqueous solution of hydrogen peroxide to the gasifying tank while supply of air from the air source to the air pipe is discontinued so that the solution is gasified by being heated with the heater.

Method of sterilizing apparatus for supplying hydrogen peroxide gas

An apparatus for supplying a liquid under a constant pressure comprising a supply tank disposed at a higher lever than articles, i.e., containers, to be supplied with the liquid, an overflow plate partitioning the interior of the supply tank into a main tank compartment and an auxiliary tank compartment, a supply pipe having an upper end connected to the main tank compartment and a lower end position to oppose the container, replenishing means for supplying a replenishment of the liquid to the main tank compartment at a rate in excess of the rate of supply by the supply pipe per unit time, means for transferring the liquid from the auxiliary tank compartment to the main tank compartment at a rate in excess of the rate of supply, and control means for operating the replenishing means and stopping the transferring means upon the liquid level in the auxiliary tank compartment reaching a predetermined low level and for stopping the replenishing means and operating the transferring means upon the liquid level reaching a predetermined high level.

Apparatus for supplying liquid under constant pressure

An apparatus for determining the rate of discharge from a nozzle for spraying an aqueous solution of hydrogen peroxide comprises a pressure sensor for detecting the internal pressure of a pipe for supplying the solution to the nozzle under elevated pressure, and means for determining the rate of discharge from the pressure detected by the pressure sensor and the predetermined relationship of the discharge rate of the nozzle with the internal pressure of the pipe.
