Abstract
A marking particle cartridge including a container defining a marking particle storage chamber and an opening communicating with such chamber through which marking particles may pass, a removable tear strip attached to the container to cover the opening and enable the opening to be selectively uncovered, and a slide cover slidably attached to the container for movement between a first position sealing the opening of the container and a second position remote from the first position where the opening of the container is uncovered. The slide cover includes a substantially planar member and a plurality of ribs on the planar member. At least a portion of the ribs are positioned to lie in a direction at an angle to the direction of sliding movement of the slide cover between the first and second positions, such that the ribs trap and capture residual marking particles.
