Abstract
Abstract A package having three or more components is held together by multi-duty undercut in the middle component which must be made of relatively thin material. Thus, the undercut in the middle receptacle component serves both as part of cover snap means and as retainer for bottom-most component. Corner initiated rips in an article-receiving cavity are virtually eliminated by a novel indentation at the corners of the cavity.
