A receptacle for receiving and securing an object, comprising: a housing including a housing cover having an input opening in a front side of the receptacle; a drum rotatably coupled to the housing, the drum being disposed within the housing cover and having a drum roof and a drum floor forming a drum chamber for receiving an object placed into the drum and a drum access opening through which an object can be placed into the drum chamber, the drum being rotatable between a first position in which the drum access opening is accessible through the input opening and a second position in which the drum access opening is aligned with a secure drop area disposed at least one of below or behind the drum thereby allowing an object in the drum chamber to exit out of the drum chamber and into the secure drop area; a delivery door rotatably coupled to the housing, the delivery door being rotatable between a closed position in which the delivery door is oriented substantially vertically and blocks the input opening and an open position in which the delivery door allows access through the input opening to place an object into the drum chamber, the delivery door comprising an extension flap extending from a bottom portion of the delivery door downwardly and inwardly into the housing cover toward the drum when the delivery door is in the closed position; and a linking mechanism mechanically coupling the drum to the delivery door, the linking mechanism being configured such that rotation of the delivery door in a first rotational direction causes the drum to rotate in an opposite rotational direction to the first rotational direction, the relative movement and position of the drum roof, drum floor and extension flap working together to restrict access and prevent a line of sight through the input opening to the secure drop area substantially throughout the rotational movement of the delivery door and drum. a housing including a housing cover having an input opening in a front side of the receptacle; a drum rotatably coupled to the housing, the drum being disposed within the housing cover and having a drum roof and a drum floor forming a drum chamber for receiving an object placed into the drum and a drum access opening through which an object can be placed into the drum chamber, the drum being rotatable between a first position in which the drum access opening is accessible through the input opening and a second position in which the drum access opening is aligned with a secure drop area disposed at least one of below or behind the drum thereby allowing an object in the drum chamber to exit out of the drum chamber and into the secure drop area; a delivery door rotatably coupled to the housing, the delivery door being rotatable between a closed position in which the delivery door is oriented substantially vertically and blocks the input opening and an open position in which the delivery door allows access through the input opening to place an object into the drum chamber, the delivery door comprising an extension flap extending from a bottom portion of the delivery door downwardly and inwardly into the housing cover toward the drum when the delivery door is in the closed position; and a linking mechanism mechanically coupling the drum to the delivery door, the linking mechanism being configured such that rotation of the delivery door in a first rotational direction causes the drum to rotate in an opposite rotational direction to the first rotational direction, the relative movement and position of the drum roof, drum floor and extension flap working together to restrict access and prevent a line of sight through the input opening to the secure drop area substantially throughout the rotational movement of the delivery door and drum.
