Abstract

The present disclosure is directed to a method and apparatus for receiving and easily securing and latching a replenishment toner bottle onto a toner or developer material hopper of a toner using machine. As illustrated in FIGS. 1 and 2, the replenishment toner bottle (not shown) which has a lip 10 surrounding an opening 12, is positioned upside down onto the platform 14 of a bottle guide 16. The lip 10 of the bottle includes a flange portion 20 that has a tapered front end 22. The front end 22 has a width W1. The Iip 10 also has an untapered rear end 24 that has a width W2 greater than W1.

DRY INK BOTTLE CAP LATCHING MECHANISM(Cont'd)

The present disclosure is directed to a method and apparatus for receiving and easily securing and latching a replenishment toner bottle onto a toner or developer material hopper of a toner using machine. As illustrated in FIGS. 1 and 2, the replenishment toner bottle (not shown) which has a lip 10 surrounding an opening 12, is positioned upside down onto the platform 14 of a bottle guide 16. The lip 10 of the bottle includes a flange portion 20 that has a tapered front end 22. The front end 22 has a width W1. The Iip 10 also has an untapered rear end 24 that has a width W2 greater than W1.

The lip 10 of the replenishment toner bottle is pre-assembled to a bottle cap 26 so that the cap 26 closes or covers the opening 12. As shown, the lip 10, and hence toner bottle, can be separated from, and returned onto, the cap 26 in the directions as shown by the arrows 28 and 30, respectively. The cap 26 includes a backstop 32, and a pair of leaf expandable springs 34,36 attached to the sides of the flange portion 20 in alignment with the front end 22 of lip 10. The leaf springs 34, 36 each include an inwardly bent front portion having an outwardly slanted ear section 38,40, respectively for moving with each spring 34,36 from an unexpanded position W1, W3 to an expanded position W4. The leaf springs 34, 36 are expandable as such horizontally along a plane parallel to the platform 14 and cover 26.

As further shown, the bottle positioning guide 16 is mounted to a toner or developer material hopper 41, and includes the platform 14, and side walls 42,
44.
The hopper 41 includes an opening 46 that is aligned horizontally with the bottle guide platform 14, and is at a height that is suitable to seal against the lip 10 of an open toner bottle that has been slid over it from the platform 14. The toner hopper 41 also includes a front end stop 48 for engaging and stopping the front end 22 of the lip 10 when the lip 10 is fully aligned over the opening
46. To facilitate separation of the open toner bottle from the cap 26 on the platform 14 (for transfer or movement of the open bottle onto the opening 461, the bottle guide 16 includes a front end hardstop 50 that engages and prevents forward movement of the cap 26.

For proper functioning of the apparatus and method of the present disclosure, the side walls 42, 44 of bottle guide 16 include a pair of slots 52 and 54, respectively, that are aligned for receiving and retaining the leaf spri...
