<p>PROBLEM TO BE SOLVED: To keep cakes in a good cold reserving state and put in/out the cakes without losing shapes by forming a box frame wherein the cakes can be put in from a front side and successively folding to form a handle and a cold insulator housing on an upper face side. SOLUTION: A left side piece 16, an upper piece 19 and a right side piece are sequentially folded from a left end of a bottom piece 2, so that a box frame wherein cakes can be put in from a front side is formed on the bottom piece 2. Then a front piece 3 and an upper piece 4, further an adhesive overlapping part 5 for forming a handle and a housing bottom piece 8 for forming a cold insulator housing are sequentially folded from the bottom piece 2 toward the front, so that a cake container box 1 with a cold insulator housing placed on a bottom of the upper piece 4 is formed. Thus while the box is carried home, cold air flows down from a cold air hole 9 thereby keeping the cakes well in a cold reserving state, and when the cakes are to be taken out, the front piece 3 and the upper piece 4 are extended toward the front and further front flaps 17, 25 can be opened for pulling out.</p> |
