Abstract

A dry ink bottle lid must provide several functions if the material contained in the bottle is to be transferred, without complications, to the toner dispenser of an electrophotographic printing machine. Firstly, prior to installation, the lid on a full bottle ensures that the factory seal remains intact. Secondly, after installation, the lid forms an interface seal between a flange, on the bottle, and a mating gasket on the dispenser. Thirdly, when an empty bottle is removed from the printing machine, the lid prevents residual spillage.

SPRING LATCHING MECHANISM FOR DRY INK BOTTLE LID( Cont'd)

A dry ink bottle lid must provide several functions if the material contained in the bottle is to be transferred, without complications, to the toner dispenser of an electrophotographic printing machine. Firstly, prior to installation, the lid on a full bottle ensures that the factory seal remains intact. Secondly, after installation, the lid forms an interface seal between a flange, on the bottle, and a mating gasket on the dispenser. Thirdly, when an empty bottle is removed from the printing machine, the lid prevents residual spillage.

Securing a dry ink bottle lid to a toner dispenser has been accomplished heretofore by a mechanism that requires an operator to slide a full bottle into a corresponding bottle guide. The operator then turns a handle that latches the lid and actuates linkage so the bottle can be pushed into a fully seated position over the toner dispenser.

The lid comprises: a foam sealing gasket, bottle flange guide, and a single spring latch. Extra installation steps, space requirements, reliability of parts, and the cost of parts associated with this type of bottle guide mechanism led to the design of an improved spring latching mechanism. This proposed design utilizes a single...
