Abstract
Abstract The invention is an open-ended package for an article comprising a sleeve of generally rectangular cross-section. Resiliently hinged tabs are provided for retaining the article within the sleeve. The tabs are positioned so that their hinge lines are adjacent and perpendicular to the external edge of the panel to which it is hinged. The tabs are of a length greater than the depth of the sleeve. As a result, when the tabs are bent into the interior of the sleeve in an over-center position, they press toward the opposite panel of the sleeve and are thereby retained in a position traversing the open end of the sleeve so as to effect retention of the article in the package.
