Abstract: A blank for forming a wrap-around carrier sleeve comprising a plurality of panels connected end to end and having first and second end panels that form the bottom of the sleeve. The first end panel includes at least one retainer flap struck from the panel which is joined to the panel along a fold line. The second end panel is configured to overlap the first end panel and includes at least one male supporting tab comprising a neck and at least one shoulder, the male tab being joined to the second end panel at a fold line. The male supporting tab is configured to extend through the opening in the first panel from which the retaining flap is struck and engage with the first panel to support the retaining flap within the carrier sleeve thereby forming a three-dimensional protuberance within the sleeve that serves to limit movement of an article in the sleeve towards an open end of the sleeve.
