Patent number: 6484438Abstract: A pest control device is provided with (1) a volatile substance holder, which includes a pest control component volatilization surface and a liquid volatilization surface, and (2) an indicator, which is composed of a wick and a bottle. The pest control component volatilization surface holds a pest control component volatile at ordinary temperature so that the pest control component can be volatilized into the air, while the liquid volatilization surface is able to hold a liquid volatile so that the liquid can be volatilized into the air. The wick is for supplying the liquid to the liquid volatilization surface of the volatile substance holder, while the bottle contains the liquid to be supplied to the liquid volatilization surface via the wick. In this manner, the indicator indicates how much the pest control component, which is volatilized from the pest control component volatilization surface is left, by showing how much the liquid is left in the bottle.Type: GrantFiled: October 1, 2001Date of Patent: November 26, 2002Assignee: Sumitomo Chemical Company, LimitedInventors: Tadahiro Matsunaga, Tomonori Iwasaki

Patent number: 5872143Abstract: A pre-mix insecticidal composition is disclosed that contains (a) 0.1-10% by weight of 2,4-dioxo-1-(2-propynyl)imidazolidin-3-ylmethyl chrysanthemate, (b) 2.5-50% by weight of a fatty acid ester of 16-19 carbon atoms; (c) 2.5-30% by weight of a sorbitan fatty acid ester; (d) 0.5-1% by weight of at least one alcohol selected from the group consisting of ethanol, 1-propanol, 2-propanol, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, butylene glycol and glycerin; and (e) 40-93.5% by weight of a saturated hydrocarbon of 8-18 carbon atoms. This pre-mix insecticidal composition exhibits little, if any, precipitation when left to stand. It is sufficiently stable to be transported and is storage stable prior to formulating an insecticidal aerosol composition. A useful insecticidal aerosol composition contains 5-30% by weight of this pre-mix insecticidal composition, 40-85% by weight of water and 10-50% by weight of a propellant. The aerosol composition is stable, i.e.Type: GrantFiled: August 6, 1997Date of Patent: February 16, 1999Assignee: Sumitomo Chemical Company, LimitedInventors: Yasuyori Tanaka, Tadahiro Matsunaga
