Abstract
A disposable spray dispensing assembly for liquid materials includes a container that comprises an aerosol can, and a spray head initially detached from the container. A cap is connected to the container and includes a central recess extending into the chamber and presenting a hole. A tube within the chamber is connected to a cylindrical wall surrounding the recess. The cap is non-releasably connected to the container and hinders refilling of the chamber in order to reduce the likelihood that the chamber might contain a material different than the contents indicated on the container's label.
