Abstract: An instant beverage product includes a disposable cup, a soluble ingredient disposed in a bottom portion of the disposable cup, and a sealing layer sealed at an inner surface of the disposable cup at the bottom portion thereof to seal and enclose the soluble ingredient in said disposable cup, wherein the sealing layer is removed from said disposable cup for a predetermined volume of water being added into the disposable cup to mix with the soluble ingredient to form an instant beverage. The instant beverage product is adapted to be stacked up with another instant beverage product when the bottom portion of said disposable cup is placed in the upper portion of another disposable cup through the top opening thereof to minimize a space for packing two or more the instant beverage products together.
