NOVELTY - Portable and reusable liquid spray apparatus (10) configured to spray a liquid onto any surface, comprises: a spray housing (20) forming a liquid chamber (30) in it, where the liquid chamber comprises an opening into which a liquid can be received, and the liquid being retained within the liquid chamber; and a propellant housing (60), where the propellant housing configured to engage the spray housing, when engaged the propellant housing forming a first seal with the spray housing, where the first seal precluding spillage of the liquid from the liquid chamber.    USE - The portable and reusable liquid spray apparatus useful for spraying a liquid onto any surface (claimed).    ADVANTAGE - The liquid spray apparatus: is portable and reusable; is self-contained with propellant; easy to handle; has the ability to accept a liquid compound and then readily spray the compound upon a surface; is easily cleaned and readied for the next use where a different liquid compound may be loaded and sprayed; and utilizes the propellant source, which is cost effective and readily replaceable allowing extended spraying sessions.    DETAILED DESCRIPTION - Portable and reusable liquid spray apparatus (10) configured to spray a liquid onto any surface, comprises: a spray housing (20) forming a liquid chamber (30) in it, where the liquid chamber comprises an opening into which a liquid can be received, and the liquid being retained within the liquid chamber; and a propellant housing (60) configured to engage the spray housing, when engaged the propellant housing forming a first seal with the spray housing, where the: first seal precluding spillage of the liquid from the liquid chamber; propellant housing configured to hold a propellant within a propellant chamber; propellant have a pressure above atmospheric pressure; propellant housing further configured to form a second seal when engaged with the spray housing; second seal precluding leakage of the propellant into the atmosphere; spray housing further comprises a passage to supply the propellant into the liquid chamber; spray housing further comprises a spray valve and a spray nozzle (24); spray valve configured for releasing the liquid from the apparatus through the spray nozzle; and when liquid to be sprayed is poured into the liquid chamber and the propellant housing is engaged with the spray housing, when the spray valve is actuated, the propellant forces the liquid through the spray nozzle and out of the apparatus. INDEPENDENT CLAIMS are also included for a portable and reusable liquid spray apparatus configured to spray a liquid onto any surface, comprising either: the spray housing, an adaptor housing, where the adaptor housing configured to engage the spray housing, when engaged the adaptor housing forming a first seal with the spray housing, where the first seal precluding spillage of the liquid from the liquid chamber, and a propellant housing configured to hold a propellant within a propellant chamber, where the propellant have a pressure above atmospheric pressure, the propellant housing further configured to engage the adaptor housing, when engaged the propellant housing forming a second seal with the adaptor housing, the second seal precluding leakage of the propellant into the atmosphere, the adaptor housing further comprises a passage to supply the propellant into the liquid chamber of the spray housing, the spray housing further comprises a spray valve and a spray nozzle, the spray valve configured for releasing the liquid from the apparatus through the spray nozzle, when liquid to be sprayed is poured into the liquid chamber and the adaptor housing is engaged with the spray housing, and when the propellant housing is engaged with the adaptor housing, when the spray valve is actuated, the propellant forces the liquid through the spray nozzle and out of the apparatus; or the spray housing, the adaptor housing, the propellant housing, where the propellant cartridge contains a propellant, the propellant have a pressure above atmospheric pressure, the propellant housing further configured to engage the adaptor housing, the adaptor housing configured to engage the propellant cartridge, when engaged the adaptor housing forming a second seal with the propellant cartridge, the second seal precluding leakage of the propellant into the atmosphere, when liquid to be sprayed is poured into the liquid chamber and the adaptor housing is engaged with the spray housing, and when the propellant cartridge is engaged with the adaptor housing, when the spray valve is actuated, the propellant forces the liquid thru the spray nozzle and out of the apparatus.
