Abstract
A fluid dispensing device for use as anti-burglar device is disclosed which discharges a fluid, containing a chemical such as tear gas, into an area to be protected when an intruder causes the device to be actuated. The anti-burglar device employs an electrothermal actuator strip for causing fluid discharge when an electric current flows through it. In addition, the fluid dispensing device may also be used as a metered spray atomizing device by the addition of a timing device for periodically actuating the valve of the pressurized container for emitting sprays of atomized fluid into the atmosphere for the spray application of insecticides, disinfectants, deodorants, room air fresheners and the like.
Claims23
A fluid dispensing device for use with a pressurized container, the device comprising;
- a. a body member;
- b. means for supporting said pressurized container in said body member, wherein said pressurized container has a fluid-dispensing element adapted to release fluid under pressure from said pressurized container when actuated;
- c. dispensing element actuating means in said body member adapted to engage and actuate said fluid-dispensing element of said pressurized container;
- d. a passageway in said dispensing element actuating means having an entry section at one end thereof;
- e. an electrothermal actuator strip mounted in said body member moving between a quiescent position and an actuation position, in said quiescent position said fluid-dispensing element of said pressurized container and said dispensing element actuating means are separated from each other, said electrothermal actuator strip moving to said actuation position upon the application of an electric current whereby said electrothermal actuator strip forces said fluid-dispensing element and said dispensing element actuating means into engagement with each other, thereby causing said fluid-dispensing element of said pressurized container to be actuated, whereby fluid is released from said pressurized container to pass through said entry section and passageway.
A fluid dispensing anti-burglar device for use with a pressurized container wherein said pressurized container has a fluid-dispensing element adapted to release fluid under pressure from said pressurized container when actuated, the device comprising;
- a. a body member;
- b. means for supporting said pressurized container in said body member;
- c. dispensing element actuating means in said body adapted to engage and actuate said fluid-dispensing element of said pressurized container;
- d. a passageway in said dispensing element actuating means having an entry section at one end thereof;
- e. an electrothermal actuator strip mounted in said body member moving between a quiescent position and an actuation position, in said quiescent position said fluid-dispensing element of said pressurized container and said dispensing element actuating means are separated from each other, said electrothermal actuator strip moving to said actuation position upon the application of an electric current whereby said electrothermal actuator strip forces said fluid-dispensing element of said pressurized container and said dispensing element actuating means into engagement with each other, thereby causing said fluid-dispensing element of said pressurized container to be actuated, whereby fluid is released from said pressurized container to pass through said entry section and passageway.
A fluid dispensing device for use with a pressurized container wherein said pressurized container has a metering dispensing valve adapted to release a preset volume of fluid from said pressurized container when actuated, the device comprising;
- a. a body member
- b. means for supporting said pressurized container in said body member;
- c. dispensing valve actuating means in said body adapted to engage and actuate said metering dispensing valve of said pressurized container;
- d. A passageway in said dispensing valve actuating means;
- e. an electrothermal actuator mounted in said body member moving between a quiescent position and an actuation position, in said quiescent position said metering dispensing valve and said dispensing valve actuating means are separated from each other, said electrothermal actuator moving to said actuation position upon the application of an electric current whereby said electrothermal actuator forces said metering dispensing valve of said pressurized container and said dispensing valve actuating means into engagement with each other, thereby causing said metering dispensing valve of said pressurized container to be actuated whereby a preset volume of fluid is released from said pressurized container;
- f. and a means for periodically energizing the electrothermal actuator.
