Abstract: Base unit and receptacle for holding various household items. The base unit is comprised of a surface with channels having inwardly projecting flanges. Receptacles have a flange capable of being inserted into the channel in the base. The flange on each receptacle is rectangular in shape, preventing the receptacle from being rotated when in the base channel. The invention is particularly useful for persons who have difficulty unscrewing lids on bottles due to limited use of their hands.
