Patent number: 10112831Abstract: A method of producing chlorine dioxide involves generating chlorine dioxide gas by deforming a container body of a chlorine dioxide generator which is deformable in response to application of a force to the container body from outside of the container body. The deforming of the container body causes an enclosure contained in the cylinder body to be broken to bring an aqueous chlorite solution into contact with a solid acidic composition to generate chlorine dioxide gas that is discharged via a gas discharge port of the container body to outside of the container body. The method additionally involves submerging in water at least the gas discharge port of the container body during the generation of the chlorine dioxide gas to dissolve the chlorine dioxide gas discharged via the gas discharge port in the water.Type: GrantFiled: December 13, 2016Date of Patent: October 30, 2018Assignee: TAIKO PHARMACEUTICAL CO., LTD.Inventors: Fumihiro Ozawa, Shigeo Asada, Koichi Nakahara, Kazuhiko Taguchi

Patent number: 9533272Abstract: A chlorine dioxide generator includes a container body deformable in response to application of a force from the outside. The container body contains therein a solid acidic composition and an aqueous chlorite solution under a non-contact state from each other. The solid acidic composition comprises a porous material containing an acidic substance. The aqueous chlorite solution is sealed within an easily breakable enclosure. In operation, when the container body is deformed, the enclosure contained therein is broken to bring the aqueous chlorite solution into contact with the solid acidic composition, whereby chlorine dioxide gas is generated. This generated chlorine dioxide gas is discharged via a gas discharge port to the outside of the container body.Type: GrantFiled: March 6, 2012Date of Patent: January 3, 2017Assignee: TAIKO PHARMACEUTICAL CO., LTD.Inventors: Fumihiro Ozawa, Shigeo Asada, Koichi Nakahara, Kazuhiko Taguchi

Patent number: 9315911Abstract: An electrolyzer apparatus includes an anode tank having an anode and a cathode tank having a cathode which are provided separately from each other. The anode tank includes a feed opening for feeding electrolytic solution into the tank, an anode aeration device for feeding aeration air to the fed electrolytic solution, and a gas extraction pipe for guiding gas generated from the anode tank to outside the tank. A communication pipe allows the amount of electrolytic solution fed into the anode tank to flow into the cathode tank, and via the electrolytic solution in the communication pipe, electric conduction becomes possible between the anode and the cathode. An amount of gas generated by an electrolysis reaction inside the anode tank is discharged to the outside of the anode tank via the gas extraction pipe together with the aeration air. The electrolytic solution introduced into the cathode tank is discharged continuously.Type: GrantFiled: March 17, 2011Date of Patent: April 19, 2016Assignee: TAIKO PHARMACEUTICAL CO., LTD.Inventors: Shigeo Asada, Kazuhiko Taguchi, Kouichi Taura, Koichi Nakahara
