Door collar lock
An apparatus holds a door closed comprising: a top panel, a left wall and a right wall. A flap is attached to the left wall opposite the top panel and folded under the apparatus. A flap is attached to the right wall opposite the top panel and folded under the apparatus. The apparatus contains a front end, a back end and an opening at the front end that has a larger cross section than a cross section of the back end thereby providing for a tapered shape of the apparatus overall, such that the apparatus is configured to fit over two hinged arms of a door closing system, preventing the arms from articulating open to prevent the door from opening.
