ABSTRACT:
A pressure relief device for venting an internally pressurized container such as an aerosol can has three sections, a concave annular outer area, a circular central area and an annular intermediate area connecting the concave annular area to the circular area. The three sections all have the same thickness. The central area has a center point and an arc shaped score line extending through 132° to 138°, preferably 135°, about an arc center. The arc center is offset from the center point of the circular area by a distance of from about 0.290 inches. The score line has a depth of from 0.010 to 0.012 inches and is trapezoidal in transverse cross section. The intermediate area meets the circular area at an angle greater than 90° and the intermediate area meets the concave annular outer area at an angle greater than 90°.
