Abstract: An apparatus for storing marking particles is described which includes a container defining a chamber for storing the marking particles therein and having an opening defined therein for the discharge of the marking particles therefrom. The apparatus further includes a seal member secured to the container, the seal member having an opening defined therein which is at least partially coextensive with the opening of the container for the passage of marking particles therethrough. Moreover, the apparatus includes a cover positionable over the opening defined in the seal member, the cover being removably secured to the seal member with an adhesive material.
