Abstract
A vend door assembly for a vending machine from which articles are selected from a supply area and then deposited into a common vending area of the vending machine and which provides a customer access opening through which articles can be removed. It includes a delivery compartment mounted for pivotal movement between a receiving position in which articles are received through an opening therein from the article supply area, and an article retrieving position in which the opening therein is pivoted and aligned with the customer access opening in the vending area so that a customer can remove the articles from the delivery compartment. It further includes an anti-pilferage door which is mounted coaxially with the delivery compartment for pivotal movement between a first position in which it allows articles to be deposited in the delivery compartment and a second position in which it blocks access to the supply of articles through the customer access opening in the vending machine and the opening in the delivery compartment, when a delivery compartment is in its retrieving position.
