ABSTRACT:
Structures for providing a single sheet of material or a box formed from the sheet with a manually detachable coupon-bearing surface area. A cut in the sheet to a depth less than the thickness of the sheet defines at least part of the perimeter of the detachable area. A tab adapted to be manually engaged is cooperable with the cut for enabling the surface area to be stripped as a layer from the sheet, the area prior to stripping from the sheet being substantially integral with the underlying region of the sheet. Various embodiments are disclosed.
