Abstract:

A disposable medicinal application apparatus for use in the administration of a medicinal fluid comprises sealed flexible bag means at least partially filled with a quantity of the fluid to be applied. The apparatus has a neck piece freely enclosed within the sealed bag means, the neck piece being manipulable against the interior surface of a portion of the bag means and the bag wall being stretched over the neck piece. A separate applicator member has a passage in communication with discharge means. Cooperative locking and lockable means are formed on the applicator member and the neck piece, respectively, to allow the applicator member to be snap-fitted and locked to the neck piece, with the bore of the neck piece and the passage of the applicator member in alignment. A portion of the bag wall is compressed between the exterior surface of the neck piece and the interior surface of the applicator member to form a fluid-tight seal therebetween. A portion of the applicator member comprises means for puncturing the bag wall to allow egress of the medicinal fluid through the aligned bore and passage of the cooperatively locked neck piece and applicator member.
