Abstract
A dispensing system includes a decomposition chamber having a catalyst for the decomposition of hydrogen peroxide. The hydrogen peroxide and a foaming soap are provided in separate first and second chambers of a product reservoir portion of a refill unit. Decomposition of the hydrogen peroxide produces oxygen gas and water that may be used as a propellant for the creation of the foamed product, or may be used to power a pump. Additionally, the oxygen gas may be used to power a scavenger for the creation of electricity for charging a battery within the dispenser.
Claims11
A dispensing system comprising:
- (a) a decomposition chamber containing a catalyst for the decomposition of hydrogen peroxide to produce oxygen gas and water;
- (b) a foaming soap pump in fluid communication with a foaming soap reservoir;
- (c) a passage extending between the decomposition chamber and the foaming soap pump;
- (d) a scavenger for generating electricity;
- (e) a passage extending between the decomposition chamber and the scavenger;
- and
- (f) a rechargeable battery in communication with the scavenger.
A method of dispensing a foam product comprising the steps of:
- (a) introducing hydrogen peroxide into a decomposition chamber containing a catalyst to decompose the hydrogen peroxide and produce water and oxygen gas;
- (b) introducing the oxygen gas and water into a mixing chamber;
- (c) introducing a foaming soap concentrate into the mixing chamber to mix with the oxygen gas and water and form a foamed product;
- (d) dispensing the foamed product;
- and
- (e) powering an energy scavenger using the oxygen gas to generate electricity.
