A container assembly for a substance to be applied is provided that includes a
injector housing, an application tip, and a closure cap. The application tip and
the closure cap are alternatively removably securable to the outlet end of the
injector housing in a substantially fluid tight disposition. A first indicia is
associated with the injector housing and a second indicia is associated with each
of the application tip and the closure cap. The second indicia has an identity
correspondence with the first indicia such that the presence of both the first
indicia on the injector housing and the second indicia on the respective one of
the application tip and the closure cap secured to the outlet end of the injector
housing confirms that only the appropriate application tip or the appropriate closure
cap has been secured to the injector housing.
