1. A system for equalizing pressure, the system comprising:

  • a reservoir having a port and an interior volume for containing fluidic media;

    a plug positioned relatively offset to the port of the reservoir, the plug for closing the port of the reservoir when the plug is in a closed position; and

    a structure having a chamber in flow communication with the interior volume of the reservoir, the chamber for collecting fluidic media expelled from the interior volume of the reservoir through the port in a case where a pressure difference exists between the interior volume of the reservoir and the chamber before the plug is held in the closed position;

    the system further comprising;

    a first housing portion adapted to be carried by a user; and

    a second housing portion configured to be selectively operatively engaged with and disengaged from the first housing portion;

    the reservoir supported by one of the first and second housing portions; and

    wherein the plug is positioned to close the port of the reservoir when the first housing and second housing portions are operatively engaged.
