Abstract
A mounting cup for an aerosol container having radially outward extending dimples on the body portion of the mounting cup and radially inward extending indents in the skirt portion of the mounting cup; both the dimples and the indents being aligned with the longitudinal axis of the mounting cup. In the preferred form of the mounting cup, three aligned dimples and indents are spaced equidistant about the circumference of the body portion and the skirt portion, respectively. Additionally, the method of this invention comprises forming a mounting cup having dimples and indents aligned with the longitudinal axis of the mounting cup, wherein the indents are formed in the last stage of a progressive die stamping operation through displacement of the metal of the mounting cup into a recess in the outer surface of the pilot tool during the formation of the skirt portion of the mounting cup.
