Abstract:
A fluid container draining device which allows fluid to be removed from a fluid container in a controlled manner, said fluid container having walls defining a fluid filled interior region therebetween, said fluid container draining device comprising:a removable twist drill bit means having a sharpened tip and a shank with exterior channels formed thereon, and extending to a said tip;a drill bit holding means comprising a front region and a rear region, said front region being male threaded and adapted to sealingly engage an exterior portion of one of the walls of said container, the front region having an axial bore formed therethrough which communicates with said rear region of said drill bit holder means, said axial bore being sized to receive said twist drill bit means;a means to selectively immobilize said twist drill bit means in said axial bore through said front sealing region such that the sharpened tip of the drill bit means can be extended variably forward of said front region of the drill bit holding means; anda fluid valve means positioned at said rear region of said drill bit holding means and in fluid communication with said fluid container, said fluid valve means providing fluid flow control between the interior of the fluid container and the rear region as fluid flows along said exterior channels, wherein rotation of said fluid container draining device causes said twist drill bit means to rotate and cut into and penetrate the walls of the fluid container and simultaneously causes the male threaded front region of the drill bit holding means to be screwed into the walls of the fluid container, thereby permitting the front region to effectively seal against one of said container walls to prevent leakage therefrom.
