摘要

The mailbox is comprised of a rectangular box that is inclined at a 60-degree angle relative to the horizontal and forms a set with other mailboxes. An access door is pivotable about a horizontal hinge to position above half of the upper face of the box. A groove is formed on the access door that can be operated smoothly. The access door also ensures that the mail inside the box remains supported.
