초록 ▼

The present invention comprises a spray bottle in which the pressure resulting from the gripping force applied by the user is amplified and this increased pressure used in generating a spray such as an aerosol or fluid stream. In its preferred embodiment, the invention includes a high pressure chamber and a corresponding piston which is operative for driving fluid out of this chamber at high pressure through a spray nozzle and a low pressure chamber and corresponding piston which is acted upon by the hydraulic pressure within the bottle resulting from the gripping force. The low pressure chamber and piston are of larger size than the high pressure chamber and piston. The pistons are rigidly connected so that the force created by the pressure acting on the piston in the low pressure chamber is transmitted to the piston in the high pressure chamber where it is applied over a more limited area thereby generating greater hydraulic pressure for use in forming the spray.

A spray bottle adapted for holding at least one fluid and producing a media of this fluid upon being squeezed, said spray bottle comprising: (a) a resilient container for holding said at least one fluid within its interior; (b) a fluid spray discharge member including a spray nozzle; (c) a housing constructed and arranged for being mounted on said container, said housing including: at least two high pressure chambers in controlled communication with said spray nozzle and a fluid within said container, and at least two pressure chambers in communication with the atmosphere outside said container; (d) at least two hydraulic assemblies constructed and arranged to drive said fluid out through said nozzle at high pressure each of said hydraulic assemblies including: a first piston which is slidably mounted in said high pressure chamber for applying pressure to any fluid within this chamber, and a second piston of greater diameter than said first piston which is slidably mounted in said low pressure chamber so as to partition this chamber off from the interior of said container and which is rigidly connected to said first piston so as to be movable therewith, said piston being operative for being displaced within said low pressure chamber when said bottle is squeezed; and (e) valve means for controlling the transfer of fluid into and out of each high pressure chamber so that fluid will flow out of said high pressure chamber through said nozzle when said bottle is squeezed and
