1. A cap securable to a receptacle and comprising:
a lower portion for inserting into a receptacle opening; an upper portion having an opening formed therein, the opening defining an open end that is configured for engagement by a receptacle transport mechanism; a plurality of locking arms extending toward the lower portion of the cap and configured for engaging a portion of a receptacle to secure the cap to the receptacle when the lower portion is inserted into the receptacle opening, each of the locking arms extending axially from an annular flange extending radially with respect to a centerline of the cap and defining a gap between an outer surface of the lower portion and an inner surface of each locking arm, wherein the gap is sized to receive a lip surrounding the receptacle opening when the lower portion is inserted into the receptacle opening and the locking arms securely engage the lip surrounding the receptacle opening; and a plurality of longitudinally extending linear ribs disposed on an inner surface of the cap, the inner surface of the cap being defined by the opening formed in the upper portion, wherein each of the linear ribs has associated therewith at least one of: (i) an enlarged portion proximate a distal end thereof, and (ii) a recess disposed on an outer surface of the upper portion, wherein the recess corresponds in length with the associated rib and is disposed on the outer surface opposite the associated rib.
