The invention provides a mixing and dispensing pouch for applying a wound dressing onto a wound. The pouch includes a pair of superimposed sheets, e.g., of plastic film, connected together at their edges. A pressure-rupturable seal is located between the super-imposed sheets and extends from one edge of the package to the other to form two compartments. The pressure-rupturable seal can be forced open manually by applying pressure on the exterior of the package with the hands so as to increase the hydrostatic pressure in a liquid, e.g., water contained in one compartment of the package causing the seal to rupture and the liquid to spurt through the ruptured seal, mixing with a dry wound dressing contained in the other compartment. If required, additional kneading of the package with the hands will mix the wound dressing for use as soon as it is expelled from the package. The package can be provided with notches to facilitate tearing the package open manually and, if desired, a pour spout with a frangible portion that can be removed so that the fluid dressing can be expelled through the spout.
