A pull-top lid for a pressurized tennis ball container having a rubber safety shield for protecting against injury from the sharp pressing seam edge of the removed lid.The rubber gasket-like safety shield being bonded to the upper surface of the top enclosure panel and reaching beyond the pressing seam of the lid such that protection against injury is provided by the shield being extended beyond the sharp edge of the sheet metal.An alternative embodiment having an outer perimeter comprised of an arch shaped extension arm extending across the pressing seam and resting upon the circular lip of the raised rim. The lid upon being pulled off the the top panel synchonously causes the extension arm to wrap about and encapsulate the sharp edge of the pressing seam thereby preventing injury of any body parts.
