Abstract
An access opening closure device is provided for enabling passage of food or medication into a confined space without providing direct access from within the confined space to outside of the confined space. The device includes a housing assembly including a body and a cover, and a slide assembly including an access door and a frame. The body defines a receptacle and first and second openings. The housing assembly is pivotally coupled to the slide assembly and is movable from an operative position to a stowed, non-operative position.
