Depositing device for cargo carried by an aerial vehicle

A depositing device for a cargo carried out by an unmanned aerial vehicle, comprising:

• a receptacle comprising a peripheral sidewall extended around a bottom member, said receptacle is enclosed from above by at least one swinging ledge forming a cargo-dropping area on an outer surface thereof, wherein the receptacle is coupled to a hanging device adapted for hanging said depositing device;
• wherein, said depositing device is connected with a controller comprising a transmitter and designed to transmit information usable by the unmanned aerial vehicle to determine a spatial position of the cargo-dropping area;
• wherein, said at least one swinging ledge is designed to tilt downwards into the receptacle for inserting said cargo into the receptacle, in case a force exerted by a weight of the cargo imposed on the cargo-dropping area exceeds a weight-threshold;
• and wherein said depositing device further comprises a lock mechanism which prevents said at least one swinging ledge from tilting after one time of tilting downwards thereby preventing inserting further cargo after counting one time of inserting the cargo into the receptacle, wherein said lock mechanism is to reset and restart the counting.
