Abstract
A novel mail carrier sorting case arrangement facilitates the sorting of mail according to current conditions. Compartments formed in a case by vertical dividers are provided for each delivery address. Flags reflecting special current delivery situations with respect to particular addresses are temporarily placed across the entrances to corresponding compartments which must be noted by the sorting mail carrier when inserting the mail. The flags are obstructions which will be noticed physically if not visually, and may be readily deflected. The flags are formed of a strip of flexible material mounted on one end on a spring clip readily attachable to and removable from a divider. A flag has one bending point about which the free end of the strip moves inward facilitating the easy insertion of a single piece of mail into the compartment. The strips may be color coded to indicate broad categories of special situations, and may bear readily mounted and removed information cards which carry detailed instructions.
