Abstract: A spill-less wave bowl for use by pets and small children. The wave bowl is designed to prevent contents such as liquids in the bowl from spilling out over the edge of the bowl and from the bowl overturning. The spill-less wave bowl includes an inner bowl snapped to the inside of an outer shell. The inner bowl includes a bowl base in a lower portion of the bowl, sloping sides extending upwardly and outwardly from the bowl base and a circular bowl flange with snap arm disposed around an edge of an upper portion bowl. The outer shell includes a shell base in a lower portion of the shell, sloping sides extending upwardly and inwardly, an inwardly curved inverted concave-shaped lip which forms an interior concave-shaped cavity inside an upper portion of the shell. Around an inside of a center portion of the shell is a circular flange notch. The flange notch is used for receiving the snap arm of the bowl flange in a press fit for securing the inner bowl inside the shell base.
