Abstract

A dispensing apparatus and method for spraying the hands of a person is provided. The apparatus includes a housing having a plurality of walls forming a chamber for the hands and having an opening for inserting the hands into the chamber. The apparatus has an L-shaped actuating member having a pivot supported by a wall. The L-shaped member has a horizontal leg supported by the pivot, a disc portion disposed in the chamber for contact by the hands, and has a vertical leg with a tip bearing portion disposed outside the housing. The apparatus also has a resilient cantilever beam having a first portion with a cavity which receives a cap portion of an aerosol container, and having a second portion which is fixedly connected to a wall of the housing. The resilient cantilever beam has a passageway from the cavity to an orifice inside the chamber for spraying a substance. from the container, while containing the disc portion in the chamber. An upward force on the disc portion causes a downward force on the resilient cantilever beam to actuate the container. The resilient cantilever beam springs back to its release position when the force is removed and the flow of the substance is stopped.

Claims

1. A dispensing apparatus comprising:

a housing having a chamber, said housing having a plurality of walls enclosing the chamber, and an opening for insertion of the hands into the chamber;

mechanically actuating means in the form of a pivotable lever having a portion disposed in the chamber and a portion outside of the housing to actuate a pressurized aerosol container and a member having passage means for conducting the pressurized substance from the aerosol container to the chamber upon applying a force to the portion of the actuating lever disposed in the chamber, the member having passage means and being a resilient cantilever beam having a first portion with a recess for receiving a cap portion defining an outlet valve from said aerosol container and having a second portion fixedly connected to a wall, and the passage means having a passageway from the recess extending through the first portion and the second portion to an orifice disposed within the chamber for spraying therein.

2. The apparatus of claim 1, including pivot means for supporting the pivotable member, the pivotable member being an L-shaped member having a horizontal leg with a hand operable disc portion disposed in the chamber and having a vertical leg with a tip bearing portion disposed outside of the housing for applying a force to the cap portion of the aerosol container, said pivot means having a pivot pin with a pivot axis for supporting the L-shaped member, and having a pair of spaced pivot supports coaxial with the pivot pin along the pivot axis for support by a wall and for supporting the pivot pin.

3. The apparatus of claim 2, wherein the resilient cantilever beam has an upper face with a bearing recess that receives the tip bearing portion of the L-shaped member for applying a force from the tip bearing portion through the beam to the aerosol container cap portion.

4. A method for dispensing a substance comprising the steps of:

providing a housing having a chamber;

adapting the housing with a plurality of walls enclosing the chamber, and with an opening for inserting of the hands into the chamber;

providing a mechanically actuating means in the form of a pivotable lever having a portion disposed in the chamber and a portion outside the housing to actuate a pressurized aerosol container;

providing a member having passage means for conducting a pressurized substance from the aerosol container to the chamber;

adapting the member having passage means as a resilient cantilever beam having a first portion with a recess for receiving a cap portion defining an outlet valve of the aerosol container and having a second portion fixedly connected to a wall, and having the passage means as a passage way from the recess extending through the first portion and the second portion to an orifice disposed within the chamber for spraying therein; and

applying a force to the portion of the actuating lever disposed in the chamber to cause the substance within said container to be dispensed into the chamber beneath said actuating means.

5. The method of claim 4, including pivot means for supporting the pivotable lever, the pivotable lever being an L-shaped member having a horizontal leg with a hand operable disc portion disposed in the chamber and having a vertical leg with a tip bearing portion disposed outside of the housing for applying a force to the cap portion of the aerosol container, the pivot means having a pivot pin with a pivot axis for supporting the L-shaped member, and having a pair of spaced pivot supports coaxial with the pivot pin along the pivot axis for support by a wall and for supporting the pivot pin.

6. The method of claim 5 wherein the resilient cantilever beam has an upper face with a bearing recess that recieves the tip bearing portion of the L-shaped member for applying a force from the tip bearing portion through the beam to the aerosol container cap portion.

7. A dispensing apparatus comprising:

a housing having a chamber, said housing having a plurality of walls enclosing the chamber, and an opening for inserting the hands of a user into said chamber;

mechanically actuating means having a portion disposed in said chamber and a portion outside the housing to actuate a pressurized aerosol container, said mechanically actuating means having a pivotable lever, and pivot means for supporting the pivotable lever; and

a member having passage means for conducting a substance from a container to the chamber upon applying a force to the portion of the actuating means disposed in the chamber, said member having passage means is a resilient cantilever beam having a first portion with a recess for receiving a cap portion defining an outlet value of the aerosol container and having a second portion fixedly connected to a wall, and the passage means includes a passageway from the recess extending through the first portion and the second portion to an orifice disposed within the chamber for spraying therein.

8. The apparatus of claim 7, wherein the pivotable lever is an L-shaped member having a horizontal leg with a hand operable disc portion disposed in the chamber and having a vertical leg with a tip bearing portion disposed outside of the housing for applying a force to the cap of the aerosol container, said pivot means having a pivot pin with a pivot axis for supporting the L-shaped member, and having a pair of spaced pivot supports coaxial with the pivot pin along the pivot axis for support by a wall and for supporting the pivot pin.

9. The apparatus of claim 8, wherein said resilient cantilever beam has an upper face with a bearing recess that receives the tip bearing portion of the L-shaped member for applying a force from the tip bearing portion through the beam to the cap of the container.
