A DENTIFRICE CLOSURE (16) ON A DENTIFRICE TUBE (10) CAN EMIT A SIGNAL UPON THE OPENING OF THE CLOSURE (16) TO DISPENSE SOME OF THE DENTIFRICE. THE CLOSURE (16) IS COMPRISED OF A BASE PORTION (18) TO ATTACH THE CLOSURE (16) TO THE DENTIFRICE TUBE (10) AND A LID PORTION (20) THAT CLOSES THE DISPENSING OPENING OF THE DENTIFRICE TUBE (10) AND WHICH CONTAINS SWITCH TIMER AND SIGNAL GENERATOR. THE SIGNAL GENERATOR CAN BE A LIGHT, BUT PREFEREBLEY IS A SOUND GENERATOR, AND MOST PREFERABLY A MUSIC GENERATOR. UPON THE LID BEING OPENED, A SWITCH (28) ACTIVATES THE TIMER WHICH IN TURN ACTIVATES THE SIGNAL GENERATOR. REGARDLESS OF THE POSITION OF THE SWITCH (28) AFTER A LID OPENING (THE LID CAN BE QUICKLY CLOSED) THE SIGNAL WILL BE EMITTED FOR A SET PERIOD OF TIME.(FIG 1)
