Abstract
A fluid container draining device for draining fluid from a fluid container, such as an oil filter, in a controlled manner. It has a front threaded screw with a sharpened drill tip. It has an internal channel communicating between an opening at the forward end of the screw and a rear region of the threaded screw. A fluid valve is positioned at the rear region of the screw in fluid connection with the channel. The fluid valve provides fluid flow control between the interior of the fluid container and the outside of the fluid container. The fluid valve has an internally threaded front region which screws into the externally threaded rear region of the screw, and an externally threaded rear region, onto which a fluid evacuation line is to be attached. A turning portion for turning the device into the wall of the container is located on the device. The fluid valve is provided with a fitting for connection to a suction line to thereby permit fluid to be drained from the fluid container when it is coupled with a drain line, and which otherwise remains closed. When the device is drilled into the fluid container, its screw will penetrate the wall of the fluid container and enter the fluid …
