Patent ID: 7175067

Claim:
A safety device for a container comprising a housing, a slot in a wall of the housing and a tray slideable into and out of the housing through the slot to convey items placed in the tray while the tray is extended from the slot into the interior of the housing, the safety device comprising: a body mounted in the tray to have limited movement relative thereto generally in the direction of movement of the tray, means biasing said body to a forward position in which, as the tray moves into the slot, it substantially fills the cross sectional area between the tray and the slot, and a latch depending from the body, the latch having a camming surface which will cooperate with a camming surface of the tray to force the latch downward as the body moves rearwardly and a latch surface adapted to abut said wall below the slot, the arrangement being such that if the slot is obstructed by one of said items when the tray is moved into the housing the body will be moved rearwardly to a position where the latch will engage said wall to prevent reception of the tray into the housing.
