A passive valve closure for liquid medicaments, configured to permit irreversible attachment to a pre-existing bottle and reversible engagement with a dosage cup bearing lugs such that when the dosage cup engages skirt lugs on the closure, a child-resistant closure is effected. In one embodiment, the closure has a collar, a plunger, and a tapered valve seal, such that the collar has spring features which permit compression in a downward direction and skirt lugs for engagement of complementary, mated lugs of a dosage cup, said skirt lugs being positioned such that engagement requires compression of the spring features. |
