The invention is an integral container system designed for separately storing a liquid, such as a diluent, and a second substance, such as a medicament, and subsequently adding the second substance to the liquid in a simple and sterile operation. In one embodiment, a flexible I.V. bag is provided with a second substance dispensing cup containing a powdered medicament, which cup fits slidably in a sleeve passing through the walls of the bag. Fitted in the open end of the cup is a pierceable plunger. A hollow needle is held in position to pierce the plunger when the cup is pushed toward the needle. The needle is slidably held so that when it is pushed by the plunger, it will also pierce a diaphragm fitting over the sleeve. When both the plunger and the diaphragm are pierced, fluid access between the cup and the bag is had through the hollow needle. Diluent can then be injected into the cup to dissolve or slurry the powdered medicament. When the cup is pushed further toward the bag, the plunger is stopped and the medicament is expelled from the cup as the volume is reduced.

A container system for separately storing a liquid and a second substance and subsequently dispensing a mixture of the two substances comprising: container means for containing and delivering a liquid, said container means having walls defining an internal cavity; sleeve means mounted in a wall of said container, said sleeve means having a pierceable member closing one end thereof; cup means for containing the second substance, said cup means being slideably positioned in said sleeve means, said cup means having an open end; pierceable plunger means slideably positioned within said open end of said cup means; collapsible cap means positioned over the other end of said sleeve means, and over said cup means; and hollow piercing means disposed between said pierceable plunger and said pierceable member; whereby as said cup means is urged toward said pierceable member by collapsing said cap means, said piercing means will pierce both said plunger means and said pierceable member, and said plunger means will be forced inwardly of said cup means so as to force said second material from said cup means through said hollow piercing means into said container means.
