A container includes a receptacle including an upright receptacle side and a receptacle bottom that cooperate to at least partly define a container chamber. The bottom presents a peripheral margin, with the side being attached to the bottom along the peripheral margin and extending upwardly relative to the bottom along an upright container axis. The receptacle further includes a drain configured to permit material flow out of the chamber, with the drain intersecting the bottom to define a drain opening that fluidly communicates with the chamber. The drain opening is spaced inboard from the peripheral margin and is laterally offset from the container axis in an offset direction. The bottom includes first and second floor sections extending inboard from the peripheral margin and joined relative to each other along a first gutter area adjacent the drain opening. The first floor section slopes downwardly toward the first gutter area in the offset direction and the second floor section slopes downwardly toward the first gutter area in a direction opposite the offset direction, with the floor sections configured to cooperatively advance material within the chamber toward the drain opening.
