Abstract A frozen yeast-containing developed dough fills a box-like folded box or receptacle made of a cardboard material. The receptacle is formed with two top opposing rectangular closure panels which together form the top wall of the receptacle. Integral side bottom, and end walls are also provided. When the mass of dough is permitted to thaw and rise, it presses upwardly against the top, rectangular closure panels to separate them and to effect automatic and gradual opening of the receptacle as baking proceeds. The top rectangular closure panels are each provided with an elongated scored line designed to be preliminarily manually folded inwardly to form elongated, outer hook panels. When the dough mass rises, it also catches under the hook panels and draws the opposing rectangular closure panels inwardly together at the same time as the closure panels are pressed upwardly. This inward drawing constituted a force which off-sets the tendency of the expanding mass of dough to force the receptacle side walls outwardly. As a result, numerous advantages accrue. For example, a lighter weight of cardboard material may be employed, both for economy and for providing a better shaped and more quickly baked loaf. Further, the inward drawing together of the receptacle side walls prevents those side walls from bowing outwardly and imparting an undesirable corresponding bow shape to the loaf side walls.
The aRticle of claim 1 and wherein said elongated edge panels are hingedly connected to the remainder of said top panels by a scored line, said contiguous free edges being the free edges of said elongated edge panels.

The article of claim 2 and wherein the width of said elongated edge panels is substantially one-half of the width of said remainder of said top panels.
Claim 3

The article of claim 3 and wherein said peripheral wall side sections are directly and hingedly connected to said top panels by a scored line whereby said inwardly drawing force is transmitted to said side sections for pulling them inwardly.

A baking product preparation comprising a baking receptacle including a vertical peripheral wall, closure means overlying the top of the receptacle, and a frozen, yeast-containing, unraised, developed dough in said receptacle, said closure means comprising a pair of elongated top panels each hinged to recpectively opposite sides of said peripheral wall and having free edges disposed substantially centrally of the receptacle top, and hinged integral longitudinal edge sections on each of said top panels and extending inwardly and downwardly from the remainder of said top panels so as to form hook-like narrow, elongated edge panels positioned so as to be grasped and pulled by the expansion of the thawing and rising dough at the same time that said top panels are pressed upwardly by the expanding dough, whereby side sections of said peripheral wall are drawn inwardly against the action of the sides of the expanding mass of dough.
