A container apparatus, for storing sheetrock mud, includes a lid portion and a container portion attached to the bottom of the lid portion by an air-tight seal. The container portion includes a floor portion and wall portions projecting upward from the floor portion. The lid portion is attached to top portions of the wall portions. The floor portion includes four straight floor sides which form a rectangle, and four planar trapezoid-shaped wall portions project upward from the four straight floor sides. Preferably, the four planar wall portions slope outwardly from the four straight floor sides. The lid portion includes a snap-fit connection with the container portion. The scraper member has a length which is at least as long as a sheetrock blade and, when the lid portion is removed from the container portion, can be used for scraping excess sheetrock mud off of a sheetrock blade.
