The fluid container includes a housing unit including a plurality of wall portions and a fluid chamber configured to store fluid therein. The housing unit is configured to removably attach to a respective receiver slot of the receiving unit of the image forming apparatus. The fluid container also includes a first key set disposed on an exterior surface of one wall portion of the housing unit. The first key set is configured to form a first key pattern corresponding to a conforming first receiver key pattern of a respective receiver slot. The fluid container also includes a second key set disposed on an exterior surface of an other wall portion of the housing unit. The second key set is configured to form a second key pattern corresponding to a conforming second receiver key pattern of the respective receiver slot. ## Claims ### Claim 1 A fluid container usable with an image forming apparatus including a receiving unit having a plurality of receiver slots, the fluid container comprising: a housing unit including a plurality of wall portions and a fluid chamber configured to store fluid therein, the housing unit configured to removably attach to a respective receiver slot of the receiving unit of the image forming apparatus; a first key set disposed on an exterior surface of one wall portion of the housing unit, the first key set configured to form a first key pattern corresponding to a conforming first receiver key pattern of a respective receiver slot; and a second key set disposed on an exterior surface of an other wall portion of the housing unit, the second key set configured to form a second key pattern corresponding to a conforming second receiver key pattern of the respective receiver slot; and wherein the one wall portion and the other wall portion of the housing unit form an angle with each other. ### Claim 2 (depends on 1) The fluid container according to claim 1, wherein the first key pattern corresponds to a respective color of the fluid stored in the fluid container and the second key pattern corresponds to a respective fluid container family. ### Claim 3 (depends on 1) The fluid container according to claim 1, wherein the first key set comprises at least one of one or more projections and one or more projection receiving areas to conform to the conforming first receiver key pattern and the second key set comprises at least one or more projections and one or more projection receiving areas to conform to the conforming second receiver key pattern. ### Claim 4 (depends on 3) The fluid container according to claim 3, wherein each of the first key set and the conforming first key pattern comprise a combination of three projections and three projection receiving areas such that the three projections of the first key set correspond to the three projection receiving areas of the respective receiver slot of the receiving unit, respectively, and the three projection receiving areas of the first key set correspond to the three projections of the respective receiver slot of the receiving unit, respectively. ### Claim 5 (depends on 4) The fluid container according to claim 4, further comprising: a port disposed on the other wall portion of the housing unit adjacent to the second key set, wherein the port is configured to engage a port engagement member and to provide fluid communication between the fluid chamber and the port engagement member. ### Claim 6 (depends on 1) The fluid container according to claim 1, further comprising: a guide member disposed on the one wall portion of the housing unit, the guide member configured to engage the respective receiver slot and guide the housing unit therein during installation of the fluid container in the receiving unit. ### Claim 7 (depends on 6) The fluid container according to claim 6, wherein the other wall portion of the housing unit is a leading end of the housing unit during the installation of the fluid container in the receiving unit, the other wall portion of the housing unit is positioned closer to at least a portion of the guide member than the other wall portion is to the first key set. ### Claim 8 (depends on 1) The fluid container according to claim 1, wherein the angle is in a range of 85 to 95 degrees. ### Claim 9 (depends on 1) The fluid container according to claim 1, wherein a shape of the housing unit is rectangular. ### Claim 10 (depends on 1) The fluid container according to claim 1, wherein at least a portion of the first key set is color-coded to correspond to a respective color of fluid in the fluid chamber. ### Claim 11 A fluid container usable with an image forming apparatus including a receiving unit having a plurality of receiver slots, the fluid container comprising: a housing unit including a plurality of wall portions and a fluid chamber configured to store fluid therein, the housing unit configured to removably attach to a respective receiver slot of the receiving unit of the image forming apparatus; a first key set disposed on an exterior surface of one wall portion and a second key set disposed on an exterior surface of an other wall portion of the housing unit, the first key set configured to form a first key pattern corresponding to a conforming first receiver key pattern and the second key set configured to form a second key pattern corresponding to a conforming second receiver key pattern of the respective receiver slot of the receiving unit; a port disposed on the other wall portion of the housing unit adjacent to the second key set, wherein the port is configured to engage a port engagement member and to provide fluid communication between the fluid chamber and the port engagement member; and a guide member disposed on the one wall portion of the housing unit, wherein the guide member is configured to engage the respective receiver slot and guide the housing unit therein during installation of the fluid container in the receiving unit. ### Claim 12 (depends on 11) The fluid container according to claim 11, wherein the other wall portion of the housing unit is a leading end of the housing unit during the installation of the fluid container in the receiving unit, the other wall portion of the housing unit is positioned closer to at least a portion of the guide member than the other wall portion is to the first key set. ### Claim 13 (depends on 11) The fluid container according to claim 11, wherein the first key set comprises at least one of one or more projections and one or more projection receiving areas to conform to the conforming first receiver key pattern of the respective receiver slot of the receiving unit and the second key set comprises at least one or more projections and one or more projection receiving areas to conform to the conforming second receiver key pattern of the respective receiver slot of the receiving unit. ### Claim 14 (depends on 13) The fluid container according to claim 13, wherein each of the first key set and the conforming first key pattern comprise a combination of three projections and three projection receiving areas such that the three projections of the first key set correspond to the three projection receiving areas of the respective receiver slot of the receiving unit, respectively, and the three projection receiving areas of the first key set correspond to the three projections of the respective receiver slot of the receiving unit, respectively. ### Claim 15 (depends on 11) The fluid container according to claim 11, wherein the one wall portion and the other wall portion of the housing unit form an angle with each other in a range of 85 to 95 degrees.
