A pest control aerosol sprayer that is free from giving rise to a fire or a burn in its storage or use, includes a pressure-tight container receiving therein a noxious insect behavioral inhibitor of which an active ingredient is HFC-152a acting also as both a propellant and refrigerant. The pressure-tight container has at its top a valve having a stem, and the stem has an injection hole therein that can be opened with the stem forced down. A head cap is attached to a top of the pressure-tight container and is provided with a spray nozzle and an inflow port in which the stem of the valve in the pressure-tight container is fitted. The head cap has an injection passage leading from the inflow port to the spray nozzle.

A blower type chemical diffusing apparatus is small in thickness, simple in structure, and reduced in cost. The apparatus allows the chemical and a battery to be exchanged readily and facilitates electrically connecting the battery to the motor in the blower. The apparatus casing includes a first and a second side casing counterpart hinged together to allow opening and closing. The apparatus further includes a blower with a motor and fan mounted in the first casing body. A chemical cartridge is disposed between the blower and the second casing body, and contains a chemical impregnated body which includes a carrier in the form of a sheet impregnated with the chemical. The first casing body has a battery accommodating recess in which dry cells are removably accepted to drive the motor and thereby to rotate the fan. Air is thus forced to flow through the chemical cartridge.

Blower type chemical diffusing apparatus, and chemical cartridge and chemical impregnated body used therefor

A chemical cartridge for a blower-type chemical diffusing apparatus includes a chemical-impregnated body including an air-permeable and liquid-absorptive sheet impregnated with a chemical, and a retainer receptacle for containing the chemical-impregnated body. The retainer receptacle includes a liquid pool recess formed at a central area thereof such that liquid chemical stored in the liquid pool recess is permeable towards a peripheral area of the sheet.

A pest control aerosol sprayer is provided that is free from giving rise to a fire or a burn in its storage or use. The pest control aerosol sprayer comprises a pressure-tight container () receiving therein a noxious insect behavioral inhibitor (A) of which an active ingredient is HFC-152a acting also as both a propellant and refrigerant, the pressure-tight container having at its top a valve () provided with a stem () and in the stem () with an injection hole () that can be opened with the stem () forced down; and a head cap () attached to a top of the pressure-tight container () and provided with a spray nozzle () and an inflow port () in which the stem () of the valve () in the pressure-tight container () is fitted, the head cap () being formed therein with an injection passage () leading from the inflow port () to the spray nozzle ().

A fan type noxious insect control apparatus is disclosed which is desirably used carried on a user's body part and excels in noxious insect control performance. To this end, the apparatus is so configured that air is drawn through an inlet port () by driving of an axial flow fan () and passed through a chemical carrier () carrying a noxious insect control active ingredient to form the air containing such active ingredient, the air being run out through an outlet port () to diffuse the active ingredient into the ambient atmosphere and further that the inlet port () at an upstream of the fan () is open facing axially thereof, the outlet port () at a downstream of the fan () is open facing radially thereof, and there are provided an annular wall () surrounding the fan () and an air flow passage () communicating between a delivery section of the fan () and the outlet port () to convert air flowing out of the axial flow fan () axially thereof to air flowing radially thereof.

A trigger type head cap for an aerosol sprayer allows residual gas inside of an aerosol container of the sprayer to be easily and reliably discharged and eliminated. The cap includes a cap cover to be placed on the aerosol container, which has a stem provided on a top thereof; a tubular member that has a stem mating part to mate with the stem and ends with a jet orifice to form a flow path continuous from the stem mating part to the jet orifice in the tubular member; and a trigger lever member capable of thrusting down the stem mating part. In addition, the cap has a rotatable rotary stopper () to hold the stem mating part in the state that it is thrust down, and a stopper operating lever for effecting rotation of the stopper.

A blower type chemical diffusing apparatus is disclosed which can be of service for an extended period of time and does not give rise to refuse disposal problems. The blower type chemical diffusing apparatus of the invention has an air blower, a chemical retainer and a fuel cell included in the apparatus body whereby powering the air blower to drive it with the fuel cell causes chemical from the chemical retainer to be emitted into an environmental atmosphere.

A blower type chemical diffusing apparatus is small in thickness, simple in structure and reduced in cost structurally. This apparatus allows the chemical and battery to be exchanged readily and to facilitate electrically connecting battery to the motor in the blower. The apparatus casing comprises a first and a second side casing counterpart hinged together to allow its opening and closure. The apparatus also includes a blower with a motor and fan mounted in the first casing body. A chemical cartridge is disposed between the blower and the second casing body. The cartridge contains a chemical impregnated body that comprises a carrier in the form of a sheet impregnated with chemical. Also provided in the first casing body is a battery accommodating recess in which dry cells may removably be accepted to drive the motor and thereby to rotate the fan. Air is thus forced to flow through the chemical cartridge.

A head cap for an aerosol type atomizer is proposed in which a residual gas that remains in the container after the use of the aerosol type atomizer is ended are discharged easily and safely, and which is so structured that the aerosol type atomizer cannot be falsely operated while it is being used. It comprises a cap body mounted over a top of a container accommodating its contents, and a movable member for spray operation disposed inside of the cap body and having a fluid channel extending from a stem fitting part for fitting with a stem and leading to a spray port, the movable member for spray operation having a push button such that pushing down the push button to take a spray position sprays contents of the container from the spray port via the fluid channel, wherein the cap body has a side face elastically deformable so that when the push button of the movable member for spray operation is pushed down to take the spray position, pressing the side face of the cap body inwards locks the movable member for spray operation with the side face to hold the movable member for spray operation at the spray position.

Chemical diffusing apparatus

Disclosed are a chemical carrier body capable of volatilizing a chemical stably for an extended period of time, a receptacle for retaining the chemical carrier body, an indicator adapted for displaying a degree of consumption of a chemical contained in the chemical carrier body, and a chemical heating, volatilizing apparatus adapted for heating the chemical carrier body. The chemical carrier body retaining receptacle is provided with at least one vent hole and has its inner surface spaced from the carrier body by a distance of 1 to 10 mm. The indicator has a mark gradually disappearing and a mark gradually appearing with a lapse of time of heating. The chemical heating, volatilizing apparatus has a heater element that is lager in size than the bottom surface of the chemical carrier body retaining receptacle and whose heat releasing surface is inclined at an angle of 0 to 70 degrees with respect to the plane on which the apparatus is placed.
