A fluid delivery device that may be used in any orientation is presented. The device includes a container, a first fluid in the container space, an inlet opening attached to a bladder, and an outlet opening. A second fluid enters the container through the inlet opening. The bladder, which receives the second fluid as it enters the container, expands with the amount of second fluid that is received. As more of the second fluid is received and the bladder expands, the first fluid is pushed out of the container through the outlet opening. The device may be used as a tire repair system, for example by coupling the inlet opening to an air compressor and coupling the outlet tube to a tire. The first fluid that's in the container space would be a sealant composition in this case. Different embodiments of the bladder are possible depending on the application.

The invention claimed is: 1. A fluid delivery device comprising: a container defining a container space; a first fluid in the container space; an inlet opening through which a second fluid enters the container space; a bladder in the container, wherein the bladder is attached to the inlet opening such that the bladder receives the second fluid and expands as the second fluid enters the container space through the inlet opening, wherein the bladder rips upon reaching a critical bladder volume such that the second fluid that enters the container through the inlet opening exits the container through the outlet opening; and an outlet opening in the container through which the first fluid exits the container as more of the container space is occupied by the second fluid. 2. The device of claim 1, wherein the bladder is expandable to the point where the second fluid substantially fills the container space. 3. The device of claim 1 further comprising a pressure relief valve coupled to the inlet opening, wherein the pressure relief valve maintains a pressure level of the second fluid in the container space at or below a predefined level. 4. The device of claim 1 further comprising a pressure relief valve in the container, wherein the pressure relief valve couples the inlet opening to the outlet opening if a pressure level of the second fluid in the container space reaches a predefined level. 5. The device of claim 1 further comprising: an inlet tube connected to the inlet opening, wherein the inlet tube is at least partially located in the container; and an outlet tube connected to the outlet opening, wherein the outlet tube is at least partially located in the container. 6. The device of claim 1 further comprising: an inlet tube connectable to the inlet opening; and an outlet tube connectable to the outlet opening; wherein the container is separable from the inlet tube and the outlet tube. 7. The device of claim 6, wherein the inlet tube and the outlet tube have different lengths. 8. The device of claim 1, wherein the bladder comprises a flexible polymer material. 9. The device of claim 1 further comprising a screen surrounding the outlet opening. 10. The device of claim 1, wherein the first fluid is a liquid and the second fluid is a gas. 11. The device of claim 1, wherein the first fluid is a sealant composition and the second fluid is air. 12. A system for dispensing a fluid, the system comprising: a housing; an inlet tube and an outlet tube fixed in the housing; a container containing a first fluid, wherein the container is disengageably attached to the housing such that the container receives a second fluid from the inlet tube and the first fluid exits the container through the outlet tube in response to the container's receiving of the second fluid; and a bladder attached to the inlet tube that receives the second fluid and expands inside the container, wherein the bladder rips upon reaching a critical bladder volume such that the second fluid that enters the container through the inlet tube exits the container through the outlet tube. 13. The system of claim 12 further comprising: a compressor; and an inlet connector disengageably connecting the compressor to the inlet tube to transfer the second fluid to the bladder. 14. The system of claim 13 further comprising as an outlet connector disengageably connecting the outlet tube to a target object in need of repair. 15. The system of claim 12, wherein the bladder is made of a vulcanized rubber material. 16. The system of claim 12, wherein the first fluid is a sealant composition and the second fluid is air. 17. The system of claim 12, wherein the first fluid is a liquid and the second fluid is a gas. 18. The system of claim 12 further comprising a screen attached to the outlet tube. 19. The system of claim 12, wherein the bladder is expandable to the point where the second fluid substantially fills the container. 20. The system of claim 12 further comprising a pressure relief valve coupled to the inlet tube, wherein the pressure relief valve maintains a pressure level of the second fluid in the container at or below a predefined level.
