Abstract
A pump for a hand actuated device for producing an atomized spray includes a cylinder mounted with a cover cap on the neck of a container and closed in the bottom by a valve member and a stem operating a piston by means of a spring means. The discharge of the product is made through an inner passage in the stem and a lateral opening which is cleared out by movement of the piston when compressing above the spring caused by the increase of fluid pressure. The discharge pressure is so uniform and controlled by the strength of the spring, and atomization is always correct. The formation of drops as well as leakage are also avoided. The device is useful for atomizing perfumes, medicines, cleaning products, etc.
