  • Patent number: 4260082
    Abstract: A manually operated, hand-held rechargeable liquid dispensing container device having a non-pressurized, either refillable or non-refillable receptacle or reservoir, is disclosed. The device comprises a relatively reciprocating piston and cylinder defining a pressurizable chamber therebetween which can be charged with liquid from the receptacle or reservoir in the container. The piston or cylinder is reciprocated relative to the other by a charging system connected to either one which compresses a resilient means such as a spring while simultaneously drawing liquid into the chamber through a check valve at the entrance of the liquid chamber. When the chamber is charged with liquid, hydraulic pressure is exerted upon the liquid by the now compressed spring. An improved charging system permits the hydraulic pressure application to be delayed until the check valve closes, insuring a full charge in the pressurizing chamber.
