Abstract
A substance dispensing system including a first pressure vessel defining a first interior space; a first substance positioned in the first interior space; a first portion of a first propellant positioned in the first interior space; and a first portion of a second propellant positioned in the first interior space. At least 90 percent by weight of the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof. At least 90 percent by weight of the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof.
Claims5
A substance dispensing system comprising:
- a first pressure vessel defining a first interior space;
- a first substance positioned in the first interior space;
- a first portion of a first propellant positioned in the first interior space;
- and
- a first portion of a second propellant positioned in the first interior space;
- wherein a combination of the partial pressure of the first propellant and the partial pressure of the second propellant define a pressure within the first interior space,
- wherein at least 90 percent by weight the first propellant is at least one of carbon dioxide, nitrous oxide, and combinations thereof;
- and
- wherein at least 90 percent by weight the second propellant is at least one of nitrogen, argon, helium, oxygen, and combinations thereof,
- a second pressure vessel defining a second interior space;
- a second substance positioned in the second interior space;
- a second portion of the first propellant positioned in the second interior space;
- and
- a second portion of the second propellant positioned in the second interior space;
- wherein a combination of the partial pressure of the first propellant and the partial pressure of the second propellant define a pressure within the second interior space, and
- wherein the second substance includes an isocyanate reactive compound, a metal catalyst, a surfactant, a chain extender, and a blowing agent.
