Abstract: A paperboard box has removable identifying indicia. In a first embodiment, the top of the box has a central opening that may be rectangular in shape. Each corner of the opening has a removable tab and each of the tabs carries a different message. For example, the messages can relate to different kinds of pies such as, for example, “apple”, “cherry”, and “blueberry”. One of the tabs may be provided with a line to provide a location where an identifier may be handwritten using any suitable writing instrument. As an alternative example, the writing on each tab may relate to an occasion such as “Happy Birthday”, “Happy Anniversary”, “Congratulations” or “Bon Voyage”. A product is placed into the box and the cover is closed thereover. All of the tabs are removed with the exception of the remaining tab that accurately describes either the contents of the box or the occasion being celebrated or observed or other message.

Abstract: A rectangular cardboard box made from typically a single cardboard piece comprises a rectangular, tubular body having four walls terminating in end flaps which respectively connect to the walls through fold lines. The end flaps are foldable along the fold lines to close at least one end of the tubular body. The end flaps which are adjacent to each other are separated by a corner and define a first slit extending through the cardboard and along the corner between the flaps from the outer flap ends to a position which is outwardly spaced from the fold lines of the adjacent end flaps, where the first slit terminates. A second slit is defined on the inner surfaces of the adjacent end flaps. The second slit extends outwardly only partially through the thickness of the cardboard piece and defines a line that extends outwardly from the fold line of one adjacent end flap, then extending across the corner between the end flaps, and further extending inwardly to the fold line of the other adjacent end flap.

Abstract: A paperboard flat blank is scored for folding to form a container sleeve. The flat blank comprises at least first and second flat blank portions which have been sealed together along a seal line or lines to form the entire, flat blank. The majority of the area of each flat blank portion is free of contact with the other flat blank portion, i.e., the respective portions are not separate layers of a flat blank, but are separate, spaced portions thereof, connected together by one or more seal lines. The first flat blank portion exhibits at least one physical property that is different from the corresponding physical property of the second flat blank portion, other than the scoring and the shape and size in the plane of the flat blank. For example, one flat blank may be made of recycled material and the other of virgin material. The two flat blanks may have differing thicknesses, or differing surface treatment, one being impregnated with oil or plastic and the other being free of such impregnation, or the like.
