ABSTRACT:
A capsule for insertion into a bore includes a plastic container having a shank portion with one internal cavity having at least one end opening. The one internal cavity contains one chemical agent. A head element is integrally formed with the shank portion. A plastic plug sealingly closes the internal cavity. The plug is insertable into an end opening of the one internal cavity so as to provide a tight fit between the plug and the end opening. Another internal cavity is defined so as to be isolated from the one internal cavity. The other internal cavity contains another chemical agent. The shank portion has a plurality of recessed slots which are formed in the exterior surface thereof at circumferentially equal spacings. The slots extend longitudinally along a central part of the shank portion between the end opening and the head element and allow the shank portion to be broken so that as an impact force applied to the head element moves the head element towards the plastic plug, the plastic plug expands the central part of the shank portion and breaks the shank portion along the recessed slots into a plurality of strips to form passages between the strips. The chemical agents then pass from the one internal cavity and the other internal cavity through the passages.
