Abstract
A container in the form of a flat envelope, open at one end for insertion and removal of a slide, has a series of locking keys shiftable laterally to left or right from a normal, centered, rest position. When all the keys have been shifted in predetermined directions to positions representing a pre-set combination, the slide is freed for partial removal from the envelope, to an unlocking position that permits the object to be removed or in some cases to gravitate freely from the envelope. The device can be made inexpensively of injection molded plastic or plastic-coated cardboard, cheaply enough to allow it to be made as a single-use, disposable article.
