Abstract: The present invention is a portable sprayer with a tank and at least a portion of a compression chamber of a pump mechanism for pressurizing the tank located external to the tank. Thus, as a user pressurizes the at least a portion of the compression chamber external to the tank with air, the air is directed into the tank thereby pressurizing the tank.

Abstract: The present invention is a portable sprayer with a tank and a measuring device in selective fluid communication with the tank. The measuring device may be located adjacent to a funnel at the top of the tank and a valve provided to selectively control the flow of fluid from the measuring device into the funnel. The measuring device may include a plurality of surfaces extending from the internal wall of the measuring device to provide indicia of the amount of fluid within the measuring device.

Abstract: A pressurized tank sprayer includes a base tank including a neck and a mouth. A lid having a top portion and a depending skirt is positioned upon the tank. Threads are provided on the neck of the tank and engage threads on the depending skirt of the lid in order to secure the lid to the tank. The threads include locking features that prevent the lid from becoming forcibly detached from the tank during removal of the lid if excess pressure remains in the tank. An annular seal is seated in the lid and provides a seal between the tank and the lid. The annular seal includes an annular sealing surface and a concave interior surface. The annular sealing surface contacts the interior surface of the tank while the concave interior surface is exposed to the interior of the tank.
