The aerosol can is a consumer convenience item used for many years. However, safety problem have existed because the cans will burst from overpressurization as a result of over-temperature. The problem is made acute by the introduction of flammable propellants and serious concerns exist for safe transport of these cans in aircraft cargo compartments. The initial goal of this proposed project 4s to increase the working pressure from the present maximum {DOT 2Q, 270 psi) to 450 psi and to provide optional rim venting. This approach wi11 reduce fire hazard and offers the further opportunity of utilizing higher pressure nonflammable propellants. During Phase 1, efforts will be focused on three-piece cans. Laser welding of double seamed ends will be utilized to achieve high strength end seams. This technology will be compared to extrapolation of conventional double seam technology to obtain similar high burst strengths.
Anticipated Results:The improved aerosol can will reduce fire hazards on the Nation's transportation system and improve safety for the consumer market by reducing the bursting propensity.
