a barrier located inside the container, wherein prior to a breach of the barrier, said barrier separates a solvent comprising distilled water from a solute comprising sodium chloride and sodium bicarbonate; the saline solution, comprising the distilled water, the sodium chloride, and the sodium bicarbonate; and a dispenser head with a nostril end configured to form a liquid tight seal with a nostril; breaching the barrier separating the solute and solvent; responsive to the breaching, dissolving the solute and solvent to create the saline solution; pressing the nostril end of the dispenser head against a nostril; and depressing the container to push the saline solution out of the container through the dispenser and onto a surface of the sinus. ### Claim 2 (depends on 1) The method of claim 1, further comprising: separating a flexible tube from the container of saline solution to which it is attached; and coupling one end of the flexible tube to the container port and another end of the flexible tube to the dispenser head, wherein each coupling forms a liquid tight seal. ### Claim 3 (depends on 1) The method of claim 1, wherein the barrier is slidably coupled to adjacent inside surfaces of the container, said method further comprising: breaching the barrier by pulling a tab contiguous with the barrier to decouple at least a portion of the barrier from at least one of the inside surfaces of the container. ### Claim 4 (depends on 1) The method of claim 1, further comprising responsive to depressing the container to push the saline solution out of the container through the dispenser and onto a surface of the sinus, disposing the container and the dispenser. ### Claim 5 A method for rinsing an eye comprising: providing an apparatus configured for rinsing the eye, the apparatus comprising: a container configured to contain saline solution, the container having a port through which the saline solution is configured to flow when the container is depressed; a barrier located inside the container wherein prior to a breach of the barrier, said barrier separates a solvent comprising distilled water from a solute comprising sodium chloride and sodium bicarbonate; the saline solution, comprising the distilled water, the sodium chloride, and the sodium bicarbonate; and a dispenser head with an eye cup end configured to form a liquid tight seal with the eye; breaching the barrier separating the solute and solvent; responsive to the breaching, dissolving the solute and solvent to create the saline solution; pressing the dispenser head against an eye socket; and depressing the container to push the saline solution out of the container through the dispenser and onto a surface of the eye. ### Claim 6 (depends on 5) The method of claim 5, further comprising: separating a flexible tube from the container of saline solution to which it is attached; and coupling one end of the flexible tube to the container port and another end of the flexible tube to the dispenser head, wherein each coupling forms a liquid tight seal. ### Claim 7 (depends on 5) The method of claim 5, wherein the barrier is slidably coupled to adjacent inside surfaces of the container, said method further comprising: breaching the barrier by pulling a tab contiguous with the barrier to decouple at least a portion of the barrier from at least one of the inside surfaces of the container. ### Claim 8 (depends on 5) The method of claim 5, further comprising responsive to depressing the container to push the saline solution out of the container through the dispenser and onto a surface of the eye, disposing the container and the dispenser.
