Abstract
An envelope has a latching mechanism that is activated by a key to releasably secure a flap of the envelope in a closed position. The latching mechanism is located on the envelope's flap. The tip of the key fits into an aperture in the middle of the latching mechanism. Rotation of the key rotates ears on the back of the latching mechanism from a first position to a second position. In the first position, the ears align with a correspondingly-shaped opening in the front panel of the envelope, and the ears pass through the opening. Rotation to the second position rotates the ears behind the front panel such that the ears of the latching mechanism are now behind the front panel, thereby securing the opening of the envelope flap.
