A mail collection apparatus comprising a housing defining an access opening. An access door is supported by the housing. The access door is moveable between a door open position, providing access to the housing interior space through the access opening, and a door closed position blocking the access opening. A chute is supported by the housing. The chute comprises an inlet end defining a chute inlet opening adapted for receiving mail and a chute outlet end defining a chute outlet opening opposite the inlet end. A bag comprises an inlet portion defining a bag inlet opening. The bag and chute are moveable relative each other between: 1) a mail deposit mode, in which the chute and the bag cooperate to form an enclosed mail deposit pathway from the chute inlet opening to the bag inlet opening and adapted so that mail deposited through the chute inlet opening falls along the mail deposit pathway through the chute outlet opening and the bag inlet opening into the bag interior space, and 2) a mail collection mode, in which the chute and the bag are spaced apart from each other. The apparatus may be useful in helping to reduce exposure to contaminated mail that may be deposited in the apparatus.

The apparatus of claim 1 further comprising a sealing band wherein in the mail deposit mode the sealing band encircles the inlet portion of the bag and the outlet end of the inlet chute to sealingly engage the inlet portion of the bag with the chute.7. The apparatus of claim 1 further comprising a sealing band moveable between: a sealing position in which the sealing band encircles the inlet portion of the bag and the outlet end of the inlet chute to sealingly engage the inlet portion of the bag with the chute in the mail deposit mode; and a spaced position in which the sealing band is spaced apart from the bag. 8. The apparatus of claim 1 wherein in the mail deposit mode the bag inlet portion is supported by the chute.9. The apparatus of claim 1 wherein: the chute comprises one or more support members; the bag defines one or more receiving openings in the inlet portion of the bag; and in the mail deposit mode the bag inlet portion is supported by the one or more support members inserted in the one or more receiving openings. 10. The apparatus of claim 1 wherein in the mail deposit mode the bag inlet portion is supported by the housing.11. The apparatus of claim 1 wherein: the housing comprises one or more support members; the bag defines one or more receiving openings in the inlet portion of the bag; and in the mail deposit mode the bag inlet portion is supported by the one or more support members inserted in the one or more receiving openings. 12. The apparatus of claim 1 wherein the chute is unapertured between the chute inlet opening and the chute outlet opening.13. The apparatus of claim 1 wherein the chute is moveably supported by the housing.14. The apparatus of claim 1 wherein the chute is moveably supported by the housing and moveable between a chute down position, in which the chute outlet end is in the housing interior space and the chute and bag are in the mail deposit mode, and a chute up position, in which the chute outlet end is in the housing exterior space .15. The apparatus of claim 1 further comprising a clamp supported by the housing, the clamp comprising front and rear opposing clamp members, wherein the clamp is adjustable between: a clamp open mode in which the front and rear clamp members are spaced apart; and a clamp closed mode in which the front and rear clamp members are proximate each other and adapted to squeeze the bag between the front and rear clamp members. 16. The apparatus of claim 15 wherein: in the clamp open mode the clamp defines an insertion zone between the front and rear clamp members; and in the mail deposit mode at least a portion of the bag is positioned in the insertion zone. 17. The apparatus of claim 16 wherein in the clamp closed mode the front and rear clamp members squeeze the bag to form a closed bag defining a closed bag volume comprising at least a portion of the bag interior space.18.
