ABSTRACT:
A pressure relief liquid spray dispenser apparatus 10 is provided that allows a gas charged liquid spray dispenser 24 to be utilized in high temperature environments. The liquid spray dispenser apparatus 10 includes a supporting bracket 12 ) which receives a gas charged dispenser 24. The dispenser 24, having a domed shaped valve end 98 is positioned in an aperture 14 in the supporting bracket 12 so that a valve 27 on the head 98 is positioned adjacent to a control arm 50. The control arm 50 can be pivoted in the direction of the dispenser 24 to engage the valve 27 thereby releasing spray in the dispenser. The domed shaped valve end 98 of the dispenser 24 has a bellows like construction. The valve end 98 unfolds longitudinally outward when subject to excessive pressures from the expansion of the gas in the dispenser 24 at high temperatures. When this occurs the dispenser valve 27 engages the control arm 50 pivoting it away from the dispenser 24 and releasing spray in the dispenser.
