<p>A box or carton (180) for shipping, storing and microwave heating therein frozen pizzas (223) or the like. A punch down tab (222) is formed on the carton top panel (200) and a flap (220) is hinged in the carton directly beneath the tab. After the carton containing a frozen precooked pizza or the like has been removed from the freezer, a punch (61) is pushed down on the tab (or the carton is pushed up on a punch) punching the hinged tab down. The tab pushes against the flap and both of them become securely wedged against each other, or against each other and the carton bottom wall (202). A steam vent (234) in the top of the carton is thereby formed. Steam from the frozen pizza when it is microwave heated, can escape from the carton out this vent. After the carton has been removed from the oven, the user can tear open the tear tab (240) on the carton top and remove and eat the heated pizza directly from the carton, if desired.</p> |
