A shutter seal assembly for opening and sealing an aperture on a surface including a frame having raised mounting ridges along its periphery on a first side, an aperture through the frame from the first side to a second side for communication with a dispensing device on the second side and a storage chamber on the first side, a pair of mounting pivot pins on the first side. Two integral shutter spring seal members on the first side each including a cover portion at one end to cover at least one half of the aperture and shutter seal arms at the opposite end to support the cover potions; each of the arms being mounted on one of the mounting pivot pins through pivot pin mounting holes at the ends, each of the shutter seal arms having integral compression spring elements compression loaded against the raised ridges to maintain the cover potions in sealing contact over the aperture, the shutter seal arms being in contact adjacent the cover portions and being tapered to form a V-like opening at the end, the raised ridges being discontinuous adjacent the V-like opening to enable the insertion of an aperture opening actuator to force the shutter seal arms apart toward the raised ridges to move the cover portions to the open position away from the aperture.

Shutter seal assembly

A counter assembly which can be used in a toner cartridge has a generally circular rotatable actuator member fixedly mounted on one end of a shaft having a screw thread on its surface, a magnet made of a molded compliant magnetic material mounted on the screw thread surface of the shaft adjacent to the actuator member. The magnet is secured against rotational movement but is permitted longitudinal movement along the screw thread surface of the shaft. The actuator member is rotated in a direction to transport the magnet along the screw thread surface of the shaft away from the actuator.

Simple reliable counter assembly of reduced parts for a toner cartridge

A toner bottle for resupplying toner to a copying or reproduction machine having an iris type closure in the bottle mouth to control discharge of toner therefrom and prevent spilling, the iris closure consisting of a first iris member located in the bottle mouth with a second cooperating iris closure integral with a cover for the bottle, projecting tabs on the first and second iris members cooperating with the machine toner hopper to establish relative rotation between the first and second iris members on rotation of the bottle while locking the bottle in place on the machine.
