Claim:
An applicator bottle comprising: a shell defining an internal cavity with mounting members positioned at a dispensing end and a distal end of said shell, said internal cavity defining a mixing chamber from which a liquefied product can be dispensed; a movable disk positioned within said internal cavity and defining a movable distal end of said mixing chamber; a dispenser apparatus selectively connectable to said mounting member at said dispensing end of said shell to regulate a dispensing of liquefied product from said mixing chamber; a spring-loaded piston assembly selectively mountable on said mounting member at said distal end of said shell, said piston assembly being engagable with said movable disk to push said movable disk toward said dispenser apparatus and expel said liquefied product from said mixing chamber; wherein said movable disk sealingly engages an interior surface of said shell to provide a watertight mixing chamber; a tail cap member configured for connecting to said mounting member at said distal end of said shell; a telescopic plunger extendable from said tail cap member; and a lock mechanism to secure said telescopic plunger into a compressed configuration; and a base member supported on said tail cap member; an upright center post projecting upwardly from said base member and being formed with a head and a relief area below said head; a sleeve surrounding said center post and being vertically movable relative to said center post, said sleeve being biased into an upper position by a spring and being movable into a lower position by compressing said spring; and at least one detent ball carried by said sleeve and being laterally movable between an outward lock position when aligned with said head of said center post and an inward release position when aligned with said relief area.
