TONER PORT/DISPOSABLE CLOUD TRAP (Cont'd)

The idea proposed here, while primarily to facilitate adding of toner to the toner hopper of a copying machine, also has general applicability for transferring any finely divided material from one container to another without spillage or escaoe of dust.

Referring to the drawing figures, presently to add toner to the hopper 2 of a copying machine, the customer opens both the toner hopper 2 and the toner hottle 3 and pours the toner from the bottle into the open hopper. A fine toner dust can billow into the air during this process which settles on the operator, the machine, and the surrounding surfaces. Because of this, many customers prefer to wait for the machine Tech'Rep to perform the job. Also, if the customer stands back at arm's length in an attempt to keep clean, toner pouring is less controlled and mav result in spillage. In some cases, an extra cost shroud is added to the back of the toner hopper to prevent toner from spilling onto the machine parts.

The idea proposed here centers on a disposable folding trap or enclosure which provides a flexible seal 5 between the toner hopper and toner bottle. The seal 5, which is fitted between the toner hopper mouth and the toner port 6 hinged thereon, is attached to the neck of the toner bottle 3 while the opened bottle 9 in

the vertical position. Seal 5 has a connecting bellows 8 which provides the I80 of rotation needed to permit the toner bottle 3 to be upended over the toner hopper 2 while encasing the path that the neck of the toner bottle takes as the bottle is raised into position over the mouth of the toner hopper so that toner is never exp...
