  • Patent number: 4330060
    Abstract: A food serving plate for receiving and mounting cakes, pastries, and the like, is provided with a hidden, internal compartment having an opening on one side of the cake plate. A card having a message area is selectively inserted completely within the compartment through its opening to conceal the message or partially removed from the compartment to display the message. The message can be coordinated with the message decorated on the cake mounted on the cake plate and displayed at the time the cake is presented to its recipient. The card is also provided with a small tab to permit the manual removal of the card when the message area is concealed within the compartment and further provided with a slot which acts in conjunction with a leg on the cake plate to prevent the complete removal of the card from the compartment.
