Abstract
Abstract A toner container includes a containing portion and a cover. The cover is generally to be positioned adjacent a toner sump and the containing portion slid off the cover onto the sump. To prevent accidental removal of the cover when the container is not in a receiving apparatus, a releasable latch is provided for holding the cover on the container. The latch is releasable by the same motion used to position the containing portion over the sump.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A toner container comprising: a containing portion having an opening and a flange adjacent the opening, said flange having a planar bottom surface, a generally planar cover positionable against the bottom surface of the flange to cover said opening, means for holding the cover in a position over said opening, said means permitting sliding of said cover along a path between positions covering and uncovering said opening, and releasable latch means restricting relative movement of said containing portion and said cover along said path when said cover is in its covering position, said latch means comprising a handle connected to the flange on said containing portion and protruding in a transverse direction from said flange, said flange being bendable in response to an unlatching force on said handle to move said flange away from said cover, which movement releases said latch means.
Claim 2
Dependent Claim
142 words
A toner container comprising: a containing portion having an opening and a flange adjacent the opening, said flange having a planar bottom surface, a generally planar cover positionable against the bottom surface of the flange to cover said opening, means for holding the cover in a position over said opening, said means permitting sliding of said cover along a path between positions covering and uncovering said opening, and releasable latch means restricting relative movement of said containing portion and said cover along said path when said cover is in its covering position, said latch means comprising a handle connected to the flange on said containing portion and protruding in a transverse direction from said flange, said flange being bendable in response to an unlatching force on said handle to move said flange away from said cover, which movement releases said latch means.
Claim 3
Dependent Claim
149 words
A toner container comprising: a containing portion for holding toner and having a generally rectangular opening in its bottom through which toner can fall, said containing portion including a flange having a bottom surface and at least opposite side flange portions and a trailing flange portion extending laterally away from respective sides of said opening, a generally planar cover positionable against said bottom surface of said flange, said cover including means for engaging the side flange portions to hold the cover against said bottom surface in a position covering said opening, said engaging means permitting relative sliding movement of said containing portion and said cover along a path between positions in which said cover covers said opening and uncovers said opening, and releasable latch means between said trailing flange portion and said cover to prevent relative movement of said containing portion with respect to said cover along said path.
Claim 4
Dependent Claim
149 words
A toner container comprising: a containing portion for holding toner and having a generally rectangular opening in its bottom through which toner can fall, said containing portion including a flange having a bottom surface and at least opposite side flange portions and a trailing flange portion extending laterally away from respective sides of said opening, a generally planar cover positionable against said bottom surface of said flange, said cover including means for engaging the side flange portions to hold the cover against said bottom surface in a position covering said opening, said engaging means permitting relative sliding movement of said containing portion and said cover along a path between positions in which said cover covers said opening and uncovers said opening, and releasable latch means between said trailing flange portion and said cover to prevent relative movement of said containing portion with respect to said cover along said path.
Claim 5
Dependent Claim
98 words
The container according to claim 2 wherein said latch includes ramp means integral with said cover, said ramp means having a latching surface and a ramping surface, and said latch means further including a handle connected to said trailing flange portion, which handle includes a latch surface positionable against said latching surface of said ramp means when said latch means is in a latching condition, said handle being positioned to bend said trailing flange portion in response to force applied in a predetermined direction to cause releasing of said latch by raising said handle above said latching surface.
Claim 6
Dependent Claim
54 words
The container according to claim 3 wherein said handle is positioned to engage said ramp surface during movement of said containing portion along said path in a direction covering said opening, said engagement causing raising of said handle to position said handle behind said latch surface to latch the containing portion to the cover.
Claim 7
Dependent Claim
39 words
The container according to claim 4 further including stop means on said cover for limiting movement of said containing portion with respect to said cover in a direction opposite to the direction of movement in releasing said latch means.
