Abstract: A grinder includes a hopper having a top and a bottom and a shaft disposed within the hopper and configured to rotate about a shaft longitudinal axis with respect to the hopper. The shaft includes both a first end nearer to a top of the hopper as compared to a bottom of the hopper and a second end nearer to the bottom of the hopper as compared to the top of the hopper. A blade extends a radial distance outward from the shaft a smaller radial distance at a location on the shaft nearer to the first end of the shaft as compared to a second location on the shaft nearer to the second end.

Abstract: A container includes a base and a side wall integrally formed with and extending upwardly from the base to define an interior volume for holding a substance. The side wall and the base are formed of a microwave-safe material. The side wall has an outer side wall surface facing toward ambient and an inner side wall surface facing toward the interior volume. The side wall has a first region in which a wall structure is located offsetting the outer side wall surface on the wall structure from a recessed outer surface, which is offset outwardly from the inner side wall surface and inwardly from the outer side wall surface on the wall structure. The side wall is configured to be gripped by a user's hand in the first region and the wall structure allows for air pockets to form between the user's hand and the recessed outer surface.
