Abstract
Abstract A packaging structure, more particularly a beer case packaging structure having a reusable tray and a disposable sleeve, includes scoring outlining an openable closure flap for the packaging structure in the top panel of the structure. A blank for forming a disposable sleeve and having suitable crease and score lines is provided. The scoring outlining the flap may be provided by two closely spaced score lines, one formed through part of the thickness of the blank from one side and the other formed through the remainder of the thickness from the other side. The openable closure flap is hinged about one lateral side edge of the top panel and includes a tab at its free end positioned to coincide with a handhole in the structure so that the packaging structure may be temporarily reclosed.
