Container system with integral second substance storing and dispensing means
First Claim
1. 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.

Abstract
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.

9. A container system for separately storing a liquid and a second substance and subsequently dispensing the second substance into the liquid comprising:
-
container means for containing and delivering a liquid having wall means defining an internal cavity; sleeve means passing through the wall means having a first closed pierceable and extending into said internal cavity, and a second end disposed outside of the container; cup means for containing a quantity of the second substance, said cup means being closed at one end and open at the other end, said open end fitting snugly and slideably within said second end of said sleeve means; collapsible cap means sealingly closing said second end of said sleeve and thereby enclosing said cup means within said cap means and sleeve means; plunger means fitting snugly and slideably within the open end of the cup means, and having a pierceable portion; and hollow piercing means positioned such that, when the cup means is pushed into the sleeve toward said first end of said sleeve and the plunger means is thereby pushed in the same direction, said piercing means pierces both said pierceable portion and said pierceable end thereby providing fluid access between said container means and the cup means. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An I.V. bag system for separately storing a medicament and a diluent and for subsequently mixing the medicament with the diluent prior to delivery, said system comprising:
-
a container for storing the diluent and for delivery of the mixed diluent and medicament, said container having wall means defining an internal cavity; sleeve means passing through the wall means whereby a first pierceable end of the sleeve means communicates with the internal cavity and the second end is disposed outside of said container; cup means for containing a quantity of the medicament, said cup means being closed at one end and open at the other end, said open end fitting snugly and slideably within the second end of the sleeve means; plunger means fitting snugly and slideably within the open end of the cup means, and having a pierceable portion; a hollow pin with a first sharp end disposed such that, when the cup means is pushed into the sleeve means toward said first end of said sleeve means and the plunger means is thereby pushed in the same direction, said first sharp end pierces said pierceable portion thereby providing fluid access between the hollow pin and the cup means; a pierceable diaphragm positioned at said first end of said sleeve means, and guiding means in said sleeve means for slideably holding said hollow pin whereby when the hollow pin is pushed by the plunger means within said guiding means toward the first end of the sleeve means, a second sharp end thereon pierces the diaphragm of said sleeve means thereby providing fluid access between the hollow pin and the internal cavity. - View Dependent Claims (18, 19, 20, 21, 22)
