ABSTRACT:
A security holder consisting of a frame having an enclosed region presenting an opening through which an article such as a cassette may be inserted, and an extended handle portion which makes the holder difficult to conceal. A pair of opposing ramps which are slightly beveled and molded integrally into the side walls of the frame adjacent the opening of the enclosed region distort the frame when the article is inserted through the opening, and irremovably retain the article within the enclosed portion once the trailing edge of the article passes the ramps. In order to permit the frame to flex or distort sufficiently as the leading edge of the article is pressed through the opening between the ramps, a portion of the surface of the frame closely proximate to the ramps is cut, thinned, apertured, or otherwise weakened. Other angled projections on various portions of the holder frame are used to align or direct the motion of the article as it is inserted into the enclosed potion. The holder is molded from a highly translucent white polyethylene to permit viewing of the article directly through the frame, and once the article is received within the holder the frame cannot be manually manipulated or distorted to remove the article. A portion of the frame must be cut in order to remove the article.
