Patent attributes
A vessel, e.g., a bowl, suited for holding water or foodstuff for use as a pet bowl or human kitchen houseware may be. The bowl may have a modular design to allow for different portions of the bowl to have different attributes. The vessel is scaled for use by pets or humans. Generally, this means that an inner surface of the vessel defines a volumetric space of 60 cubic centimeters to 30 liters for holding water or foodstuff. The bowl has a water level, and, at the water level, the surface area of the bowl may be 56 cm to 900 square cm. To facilitate lifting and gripping by one or two human hands of a user, the vessel's outer surface may include one or more graspable elements disposed between the top and bottom of the vessel. Each graspable element is configured to receive one or more fingers of a user so that the user can grasp or otherwise engage the graspable element and lift the bowl from a surface when the bowl is upright on the surface.
