Abstract
A diaper equipped with a view flap that allows a guardian to determine whether or not the diaper needs changing with a minimum of intrusion and bother, in that partial disrobing of the diaper is obviated. The view flap diaper according to the present invention is composed of a diaper member having an aperture and a view flap member wherein the view flap member is selectively openable and closable with respect to the aperture of the diaper member. A liquid absorbent inner layer bonded with a liquid impermeable outer layer is the preferred diaper structure. The inner layer may include a liquid permeable liner, and may not have areas of differing absorbency.
