The cake is held in clamped relation within the carton by a closure flap foldably connected to the bottom edge of a rear panel which is the mirror-image of the front panel. A slide may be placed in the carton between the front panel and cake. The slide is provided with openings which are moved into and out of registration with the openings of the front panel to open and close the front diffusion panel.
