Abstract

This article describes an assembly for loading dry toner powder into the reservoir of a replenisher apparatus within a bottle which is inverted and secured to the cover of the reservoir in an arrangement in which both the bottle and reservoir cover remain closed. Further relative movement between the bottle and the cover is needed to open the closures to permit toner to flow from the bottle into the replenisher. After filling the reservoir, the bottle may be removed without toner spillage even though the bottle has not been completely emptied.

Toner Load System

This article describes an assembly for loading dry toner powder into the reservoir of a replenisher apparatus within a bottle which is inverted and secured to the cover of the reservoir in an arrangement in which both the bottle and reservoir cover remain closed. Further relative movement between the bottle and the cover is needed to open the closures to permit toner to flow from the bottle into the replenisher. After filling the reservoir, the bottle may be removed without toner spillage even though the bottle has not been completely emptied.

The figure shows the toner bottle in place on the replenisher with both the bottle and the replenisher cover closed. A toner bottle 200 has a conical portion 202 leading to a cylindrical cap 204 with a conical closed bottom 206, and dispensing openings 208 in the lower half of its cylindrical wall. A cylindrical closure and valve member 210, open at both ends, surrounds the cap and is slidable thereon. The closure member 210 covers the area of the cap 204 containing the openings 208 and is sealed to the cap by O-rings 212 and 214 above and below the openings. A mechanical detent (not shown) between the cap 204 and the closure member 210 normally maintains the closure member positioned over the dispensing openings. and thus the bottle is securely closed.

The closure member 210 includes radially extending tabs 216 which function as locating and locking means to cooperate with claws 218 on a slidable cover 220 of the replenisher. The claws 218 are disposed around a refill hole 222 in the cover 220, which itself is surrounded by a half O-ring seal 224 which engages and seals against the open mouth of the member 210. The seal 224 is surrounded by an annular wall 226 from which the claws 218 protrude to form the bottle mounting mechanism. Thus, the toner bottle may be located on the bottle mountin...
