An apparatus and method is disclosed for an improved mounting cup for sealing with a container of an aerosol device. The container includes an annular bead extending about an opening in the container with the annular bead defining an internal surface contour having a generally partially circular cross-section. A mounting cup comprising a peripheral rim is formed for sealing with the annular bead of the container. The peripheral rim has an inner region contour substantially different in shape from the inner surface contour of the annular bead of the container. The inner region contour of the peripheral rim engages with the inner surface contour of the annular bead to allow only a portion of the peripheral rim of the mounting cup to contact the annular bead of the container when the mounting cup is disposed on the container. The inner region contour of the peripheral rim is deformed when the mounting cup is crimped to the annular bead of the container to reform the inner region contour of the peripheral rim to be substantially the same shape as the inner surface contour of the annular bead to provide a sealing engagement between the mounting cup and the container.
