Abstract
A single service container having a closure cap with a recessed portion extending generally interiorly of said container. A tab is defined by a score line which, upon deflection of a an actuating member on the cap, substantially separates from the remainder of the recessed portion forming an opening in the cap. Once the tab has been separated, it is deflected through the opening and prevented from obstructing the opening by the actuating member being positioned in an interference relationship between the interior of the container, adjacent the opening, and the tab.
