Liquid spray system

Abstract

A spray system for dispensing a homogenous mixture of a liquid formulation and propellant as an atomized aerosol where a disposable container containing a liquid base is used alone or secured within a rigid container and is charged through a fitting in fluid communication with the interior of the disposable container using a detachable pressurized charge can containing a propellant compatible with the liquid base. Preferably the liquid formulation is a paint base that can be tinted at the point of sale before charging with the charge can.

1 . A spray system for liquids comprising, in combination,
 a) a disposable container having an upper end, lower end, and an interior cavity, where the lower end has an inlet fitting that is in fluid communication with the interior cavity;   b) a sealing cap configured for removable connection to the upper end of the disposable container and containing a bearing surface;   c) a valve assembly comprising an fitting, a flange and a dip tube configured to fit within the upper end of the disposable container such that the dip tube is within the interior cavity, where the flange is configured to form a seal with the bearing surface of the sealing cap; and   d) a charge can comprising an outlet fitting, where the outlet fitting is configured to allow fluid communication with the inlet fitting.
