  • Publication number: 20060048652
    Abstract: Disclosed is a cake decorating device, suitable for producing a more dramatic and attractive atmosphere of the place where various celebratory events are held, while displaying a congratulation message or picture on the decorating device by heat conduction. The cake decorating device includes a base having locking grooves formed at an upper surface of the base, and a support plate having locking protrusions formed at a lower surface of the support plate to be fitted into the locking grooves of the base. The support plate has a plurality of candles. Also, a transfer paper having a message printed using a thermosensitive microcapsule product is attached onto a wall of the base, whereby the message can be displayed by heat conduction of the candles. Thus, the atmosphere of the celebratory event is beautifully produced and reaches the climax by the cake decorating device.
