A package for dispensing fluids including two concave walls interconnected along their peripheries at least one of the walls being flexible and one of the walls having a closure intended to be opened to dispense fluids when the flexible wall is deformed toward the other wall. Preferably, the flexible wall is resilient, tending to snap over to the corresponding convex position, complementing the other wall when the resilient wall is deformed beyond the intermediate position between the walls. Preferably, also the closure is self-closing and positioned in a neck formed in one wall. A removable seal member may be positioned in the neck to protect the self-closing closure.
