Abstract: A self-contained portable solar powered fluid pump dispenser for concrete release agents having a movable supporting base pallet upon which a bulk container of release agent fluid is carried, along with a supporting framework which carries a solar panel, electric pump and rechargeable battery that is energized by the solar panel. An elongated dispensing hose is coiled on a hose reel carried by the supporting framework, such that the dispensing hose and dispensing wand connected thereto may be efficiently stored when not in use. The solar powered pump is fluidly sealed between the bulk container of release agent fluid and the dispensing wand to prevent undesirable contaminants from entering the fluid dispensing system.

Abstract: A method that is used for control of various liquids, including storage, mixing and dispersing thereof, but more particularly pertains to an improved method that is suitable for use with substantially any type of liquid of user choice. The method is economical, simplified, environmentally friendly, and includes use of multipurpose container(s) that further include various components and/or attachments that allow for storage, mixing and dispensing there from.
