Apparatus for application of a medicinal fluid, comprising:

• sealed bag means at least partially filled with said medicinal fluid;
• a neck piece having a first end and having a generally axial bore formed therethrough in communication with said first end, said neck piece being freely enclosed within said sealed bag means and adapted for manipulation of said first end against an interior surface of said bag means;
• an applicator member having opposed first and second ends, said applicator member including discharge means at said first end and having a passage between said discharge means and said second end;
• said applicator member also including means for piercing a wall of said bag means to form an opening therein in communication with said bore of said neck piece;
• lockable means formed upon an exterior surface of said neck piece adjacent said first end and comprising at least one channel formed to a selected depth into the exterior surface of said neck piece and extended from said first end of said neck piece;
• locking means formed upon an interior surface of said applicator member within said passage and adjacent to said second end and comprising a similar number of lug means radially extending inward into the passage of said applicator member adjacent to said second end;
• each channel in said neck piece being adapted to slidingly receive an associated lug means and to securely lock said lug means in said channel with a portion of said bag means compressed between said channel and said lug means;
• said locking and lockable means being adapted to cooperatively lock said neck piece and said applicator member together with a portion of the wall of said bag means compressed between said neck piece and said applicator member to form a substantially fluid-tight seal;
• wherein said lockable means further comprises a recess formed at the end of said neck piece channels furthest from said first end of said neck piece, said recess having a greater depth into said neck piece than the depth of said channel to snaplockingly receive an associated lug means.
