pastry box
A box designed for carrying multiple pastries such as cupcakes or doughnuts, usually either a half dozen or a whole dozen. Two common designs are seen - one as a long flat box that the pastries can sit in without being ruined; the other as a square box with flaps that open at the top and have a slot at the top for easy carrying.
