Abstract
A self metering dispensing device for dispensing a predetermined quantity of material from an aerosol container. First and second actuating members are pivotally connected to a housing for the container and a nozzle actuating member is connected to the first actuating member. A pneumatic member in the form of a cylinder with a piston or a telescoping valve is operatively associated with the first and second actuating members. A compressive force placed on the second actuating member causes the nozzle activating member to contact the container valve to dispense product from the container. A controlled metering of product is produced by an air regulator connected to the pneumatic member.
Claims21
A self metering dispensing device for dispensing a predetermined quantity of material from a container having a nozzle comprising:
- a housing defining a support for the container;
- first and second actuating members pivotally connected to the housing;
- a valve activating member connected to the first actuating member;
- a fluid cylinder member having a reciprocating piston therein, the cylinder including a fluid regulator;
- a reciprocating rod operatively connected to the piston, the cylinder member and the rod operatively associated with the first and second actuating members;
- and
- a first and second biasing member connected to the housing and the respective first and second actuating members.
A self metering dispensing device for dispensing a predetermined quantity of material from a container having a nozzle comprising:
- a housing defining a support for the container;
- first and second actuating members pivotally connected to the housing;
- a valve actuating member connected to the first actuating member;
- a pneumatic member having a reciprocating piston therein, the pneumatic member including an air passage on one side of the piston and a fluid restrictor and check valve on another side;
- a reciprocating rod operatively connected to the piston, the pneumatic member and the rod operatively associated with the first and second actuating arm members;
- and
- a first and second biasing member connected to the housing and the respective first and second actuating members.
A self metering dispensing device for dispensing a predetermined quantity of material from a container having a nozzle comprising:

- and
- a first and second biasing member connected to the housing and the respective first and second actuating members.
A self metering dispensing device for dispensing a predetermined quantity of material from a container having a nozzle comprising:
- a housing defining a support for the container;
- first and second actuating members pivotally connected to the housing;
- a valve activating member connected to the first actuating member;
- a fluid compressible and self expandable member positional between the first and second actuating members, the compressible member having an air regulator operatively associated therewith;
- and
- a first and second biasing member connected to the housing and the respective first and second actuating members, the first biasing member having a biasing force greater than a compressible force of the compressible member.
