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.
Claims21
A dispensing system comprising:
- (a) a decomposition chamber containing a catalyst for the decomposition of hydrogen peroxide;
- (b) a mixing chamber;
- (c) a first pump for pumping a foaming soap concentrate into said mixing chamber;
- (d) a second pump for pumping hydrogen peroxide into said decomposition chamber;
- and
- (e) a passage extending between said decomposition chamber and said mixing chamber for providing oxygen gas and water produced from the decomposition of the hydrogen peroxide to said mixing chamber.
A refill unit for a foam product dispenser comprising a product reservoir having:
- (a) a first chamber containing a foaming soap concentrate;
- and
- (b) a second chamber containing hydrogen peroxide.
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;
- and
- (d) dispensing the foamed product.
