The package for storing and spraying small amounts of liquid comprises a formed section and a flat sheet joined together such that together they provide a compressible container for storing liquid and a conterminous system of passageways for conveying and accelerating the liquid when pressure is applied to the container, said passageway system being constructed to keep the liquid within the container without any outside means of assistance. The passageway system terminates tangentially in a turbulence space provided with at least one central nozzle aperture. To intensify the spraying effect or atomization of the liquid, two passageways are provided between the container and the turbulence space which terminate tangentially in the turbulence space offset at an angle of 180.degree.. The means designed to keep the liquid within the container consists preferably of a ruptureable seal at a site between the container and the passageway system.
A package for storing and spraying small amounts of liquid, said package comprising two sheet sections which are joined, and together provide a compressible container for storing, a conterminous system of passageways for conveying and a nozzle for spraying said liquid, said passageway system receiving liquid from the container and accelerating said liquid when pressure is applied to said container, said passageway system terminating substantially tangentially in at least one substantially circular turbulence space for imparting a whirling motion to liquid conveyed to said space, said turbulence space having at least one central nozzle aperture for discharging the liquid from the turbulence space in the form of a spray.
