Abstract

A container includes a first tray, and a second tray disposed within the space of the first tray to define a reservoir therebetween. The first tray has a first bottom wall and a surrounding first sidewall, which extends generally upwardly from the first bottom wall to define a space therein. The second tray has a second bottom wall and a surrounding second sidewall, which also extends generally upwardly from the second bottom wall. The second bottom wall has at least one aperture defined in a central region thereof, and also has an upper surface, which slopes downwardly toward the at least one aperture. The reservoir defined between the first and second trays is in fluid communication with the aperture.
