Patent ID: 7174753

Claim:
A port cover for a system integrated into a structure for injection of a material into one or more cavities in the structure, the port cover comprising: a base for coupling to the structure, the base comprising: one or more ports for injection of the material into the one or more cavities in the structure; and one or more slots; a cover for removably coupling to the base, the cover comprising one or more tabs each adapted to engage with a corresponding slot of the base; and a locking mechanism for removably securing the cover to the base to prevent unauthorized access to the one or more ports, the locking mechanism adapted to engage a projection of the base to removably secure the one or more tabs of the cover in engagement with the one or more corresponding slots of the base to removably secure the cover to the base to prevent unauthorized access to the one or more ports; wherein: the locking mechanism comprises a rotatable member having a perimeter and a gap in the perimeter; when the rotatable member is in a first rotational orientation, the rotatable member is adapted to receive, via the gap in the perimeter, the projection of the base and to allow the one or more tabs of the cover to slide upward substantially parallel to a front surface of the base to engage the one or more corresponding slots of the base to secure the cover to the base; when the rotatable member is in a second rotational orientation, the rotatable member is prevented from disengaging with the projection of the base, to substantially prevent the one or more tabs of the cover from sliding downward substantially parallel to a front surface of the base to disengage from the one or more corresponding slots of the base to secure the cover to the base; and when the rotatable member is returned to the first rotational orientation, the rotatable member is adapted to release, via the gap in the perimeter, the projection of the base and to allow the one or more tabs of the cover to slide downward substantially parallel to the front surface of the base to disengage from the one or more corresponding slots of the base to remove the cover from the base.
