Patent ID: 8403165

Claim:
A security closure-cap device for closing off the outlet connection of a storage tank storing fluid therein, the storage tank being provided with an outlet, comprising: a first outlet component connectable to an outlet connection of a storage tank; a second closure-cap component connectable to said first outlet component; said first outlet component comprising a main body portion having first end defining a connecting section for connection to the outlet connection of a storage tank, and a second end distal from the first end, a mounting flange at said first end for mounting said first outlet component to a wall, and a projecting securing element defining a first end and a second end, and having a through-opening formed therein; said second closure-cap component comprising a substantially hollow-interior main body section for cooperating with said main body portion of said first outlet component; said main body section comprising a first open end leading to said hollow interior and a second substantially closed end for forming a closure cap proper, and a securing-element receiving portion through which passes a portion of said projecting securing element; said second closure-cap component further comprising a bifurcated partition element defining a pair of walls between which walls extends said portion of said projecting securing element, with said through-opening thereof being located between said pair of walls, whereby a locking device having a shaft may pass through said through-opening, with said pair of walls preventing access to the shaft of the locking device by a cutting instrument; each said wall having at least one elongated passageway formed therein; at least one reinforcing pin positioned in a said at least one passageway of each of said pair of walls of said bifurcated partition element, whereby, when said first and second components are connected together to close off the outlet of a storage tank, the locking device securing together said first and second components is substantially tamper-proof.
