Abstract
Abstract A sealed system for collecting and removing waste imaging material from a reproduction apparatus in a waste collection container removably insertable into the reproduction apparatus so that the inlet opening of the container is positioned at discharge outlet of a pneumatic cleaning system, especially, the outlet of a cyclone air/toner separator. The container has a dual mode resilient pneumatic seal surrounding its inlet, and an integral insertion guide member. The cleaning system discharge outlet includes a spring loaded sled member and a flexible pneumatic seal connecting between the sled member and the discharge outlet to allow limited movement of the sled member. The insertion guide member of the container slides on an entrance guide path into compressed superposed engagement with the sled member to form a pneumaticaly-sealed waste material path between the discharge outlet of the reproduction apparatus cleaning system and the interior of the waste container when so inserted. Also provided is a cap for sealing the inlet opening of the container when the container is removed by engagement with the same, dual mode, resilient pneumatic seal surrounding the inlet opening of the container. Also, a mating detent system is provided, which also protects the seal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
225 words
In an waste imaging material collection and removal system wherein waste imaging material from a reproduction apparatus is collected in a removable waste collection container, which waste imaging material collection container is removably insertable into the reproduction apparatus so that an inlet opening of said container is positioned at a waste imaging material discharge outlet of the reproduction apparatus; the improvement wherein: said waste imaging material collection container has a resilient pneumatic seal surrounding said inlet opening of said container; said waste imaging material container also has an integral insertion guide member; said waste imaging material discharge outlet of the reproduction apparatus includes an entrance guide path and a spring loaded sled member and a second pneumatic seal connecting between said sled member and said discharge outlet to allow limited movement of said sled member; said integral insertion guide member of said container being adapted to slide on said entrance guide path into compressed superposed engagement with said spring loaded sled member to form a pneumatic seal between said container and said sled member with said resilient pneumatic seal when said container is inserted into the reproduction apparatus; said sled member providing a pneumaticaly sealed waste material path between said discharge outlet of the reproduction apparatus and said inlet opening of said container when said insertion guide member is so inserted in the reproduction apparatus.
Claim 2
Dependent Claim
225 words
In an waste imaging material collection and removal system wherein waste imaging material from a reproduction apparatus is collected in a removable waste collection container, which waste imaging material collection container is removably insertable into the reproduction apparatus so that an inlet opening of said container is positioned at a waste imaging material discharge outlet of the reproduction apparatus; the improvement wherein: said waste imaging material collection container has a resilient pneumatic seal surrounding said inlet opening of said container; said waste imaging material container also has an integral insertion guide member; said waste imaging material discharge outlet of the reproduction apparatus includes an entrance guide path and a spring loaded sled member and a second pneumatic seal connecting between said sled member and said discharge outlet to allow limited movement of said sled member; said integral insertion guide member of said container being adapted to slide on said entrance guide path into compressed superposed engagement with said spring loaded sled member to form a pneumatic seal between said container and said sled member with said resilient pneumatic seal when said container is inserted into the reproduction apparatus; said sled member providing a pneumaticaly sealed waste material path between said discharge outlet of the reproduction apparatus and said inlet opening of said container when said insertion guide member is so inserted in the reproduction apparatus.
Claim 3
Dependent Claim
52 words
The waste imaging material collection and removal system of claim 1, further including a cap member for sealing said inlet opening of said container when said container is removed from the reproduction apparatus by engagement of said cap member with said same resilient pneumatic seal surrounding said inlet opening of said container.
Claim 4
Dependent Claim
57 words
The waste imaging material collection and removal system of claim 1, wherein said waste imaging material discharge outlet is the bottom outlet of a vacuum system cyclone air/toner separator, and said waste imaging material collection container collects waste imaging material from said cyclone air/toner separator with a vacuum being applied to said container without substantial air leakage.
Claim 5
Dependent Claim
30 words
The waste imaging material collection and removal system of claim 1, wherein said second pneumatic seal connecting between said sled member and said discharge outlet is a foraminous hose section.
Claim 6
Dependent Claim
39 words
The waste imaging material collection and removal system of claim 1, wherein said waste imaging material collection container integral insertion guide member includes a leading edge ramp surface for slightly lifting said sled member with said insertion guide member.
Claim 7
Dependent Claim
46 words
The waste imaging material collection and removal system of claim 1, wherein said waste imaging material collection container integral insertion guide member and said sled member have a mating detent system for removably retaining said container in an operative position substantially aligned with said discharge outlet.
Claim 8
Dependent Claim
35 words
The waste imaging material collection and removal system of claim 6, wherein said detent system includes raised detent elements on said insertion guide member also functioning to protect said resilient pneumatic seal during said insertion.
Claim 9
Dependent Claim
25 words
The waste imaging-material collection and removal system of claim 3 wherein said waste imaging material collection container is positionable directly underlying said cyclone air/toner separator.
