发明名称 Delivered mail indicator system
摘要 Delivered mail indicator system for indicating when a mailbox door has been opened for the deposit of mail by the mailperson. A fluorescent or reflective lip is engaged in between the two latches of a mailbox, and when the mailbox door is opened, the lip springs upwardly and outwardly. When the mailbox door is closed, the lip or flag of the indicator engages against an upper latch handle, indicating that mail has been delivered. The delivered mail indicator is made of a suitable polymer with a flag appropriately colored for ease of visualization for indicating that mail has been delivered.
