A stiff planar sheet-form member is formed with cuts extending through its thickness and framing portions that, when removed, form an array of windows, whereby the panel that remains after removing the portions may be placed against lands on one face of a blister sheet with the windows receiving respective blisters of the blister sheet for stiffening the blister sheet. The cuts extending through the thickness of the sheet-form member also form openings that communicate at opposite respective ends with respective windows. |
