Patent ID: 6871594

Claim:
A reusable paint grenade comprising a rigid, reusable casing defining a hollow cavity therewithin and defining at least one paint ejection port and a plunger port and said hollow cavity is subdivided into a paint storage chamber, a first propellant compartment storage chamber, and a second propellant component storage chamber, a fluid-tight paint/propellant barrier separating said paint storage chamber from said first propellant component storage chamber, a fluid-tight propellant component isolation barrier separating said first and second propellant component storage chambers from each other, first and second propellant components located respectively in said first and second propellant storage chambers, and said first and second propellants, when mixed react without combustion to form a gas that is under pressure in said casing, a plunger mounted in said casing and projecting from said plunger port and directed toward said second component storage chamber, whereby depression of said plunger into said casing breaches said propellant component isolation barrier, and a breachable paint seal separating said paint storage chamber from said at least one paint ejection port.
