Abstract

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°. 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.
