• external threading complementary to said internal threading extending from said container neck;
• an abutment surface presented by said container neck for sealable contact with said cap skirt portion;
• a breakaway portion defined by said container neck;
• a contact portion defined by said cap for contact with said breakaway portion;
• a sterile solution in said container;
• and
• captive means operatively associated with said cap and said container neck;
• said cap and said container neck constructed and arranged so that when said cap skirt portion is sealed to said abutment surface, said threading is placed in a spaced apart position and when said tear away portion is removed said threads will engage;
• whereby when said threads are engaged, said contact portion of said cap will engage said breakaway portion of said container neck.
