Appl. No.:

8/569388

Inventors:

Eastman Kodak Company - Rochester NY

International Classification:

G03G 1508

US Classification:

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.

Abstract:

A container for supplying toner includes a containing portion with an opening through which toner is moved into a receiving sump. A cover for the opening is flexible enough to move in an arcuate path from a position coveting the opening to a position of storage alongside a sidewall of the containing portion. The cover is stiff enough to be pushed back to its covering position. The leading edge of the cover in its movement back to its coveting position is made concave to the direction of movement so that it will more easily enter a channel partially defined by a seal around the opening. A protrusion on the cover enters a hole in a cover holding member when the cover is in its coveting position to lock the cover in place when the container is not on a receiving apparatus. The protrusion can be pushed out of the hole, unlocking the cover by an appropriate receiving member.
