First Claim
1. A new article of manufacture comprising a blank for selectively forming an open tray and a closed carton of a size lesser than said tray, said blank being in the form of a generally rectangular sheet, longitudinal fold lines dividing said sheet into a central and two end portions, and transverse fold lines dividing said central portion into body panels and said end portions into edge panels disposed at opposite ends of said body panels, said edge panels of each end portion including two remote connecting panels and only two end panels, one of said two end panels of each end portion having fold line means for positioning said one end panel selectively coplanar with the other of said two end panels and in overlapped relation to the other of said two end panels.

Abstract
For use with frozen food products, such as dough, having a substantially larger bulk volume at an elevated temperature than when frozen, a container is erected from a container blank having a plurality of fold lines and being so arranged that, when the blank is folded along a first selection of said fold lines in a first manner, it defines a container having a bulk capacity of a first predetermined volume and, when folded along a second selection of said fold lines in a second manner, it defines an open, tray-like container having a bulk capacity of a second predetermined volume larger than the said first volume, and a base area different from the base area when the blank is folded in said first manner. The ratio of the said volumes is preferably 1:2. The blank may be glazed or lined (e.g. with aluminum foil) on at least one side thereof.

- 1. A new article of manufacture comprising a blank for selectively forming an open tray and a closed carton of a size lesser than said tray, said blank being in the form of a generally rectangular sheet, longitudinal fold lines dividing said sheet into a central and two end portions, and transverse fold lines dividing said central portion into body panels and said end portions into edge panels disposed at opposite ends of said body panels, said edge panels of each end portion including two remote connecting panels and only two end panels, one of said two end panels of each end portion having fold line means for positioning said one end panel selectively coplanar with the other of said two end panels and in overlapped relation to the other of said two end panels.
- 16. A new article of manufacture comprising a blank for selectively forming an open tray twice as wide as it is deep or a closed elongate carton of square cross-section of half the cross-sectional area of said tray, said blank being in the form of a generally rectangular sheet, first fold lines dividing said sheet into a central portion and two equal width end portions, and second fold lines orthogonal to the first fold lines and dividing said central portion into four body panels of equal width to one another and to said end portions and at least one further panel to connect the two outermost body panels together to form the said closed carton, said second fold lines further dividing said end portions into edge panels disposed at opposite ends of said body panels, said edge panels of each end portion including two remote connecting panels and square end panels which are only two in number and disposed between the connecting panels, one of said two end panels of each end portion having fold line means for positioning said one end panel selectively either coplanar with the other of said two end panels whereby the two end panels together form a side wall of the said open tray and their attached body panels are coplanar to form the tray bottom, or in overlapped relation to the said end panel whereby the said attached body panels form two adjacent body walls of the said closed carton.
