The liquid-overflow platform and container device includes a generally horizontal platform for catching overflow liquid from a small appliance, such as a coffee maker, and a container attached beneath the platform that receives the liquid flowing through apertures in the platform. The apertures are less than 10% of the platform area. The platform may be topographically structured to encourage liquid to drain into the apertures, and is larger than the footprint of the appliance. The container is sized to contain more than the liquid capacity of the small appliance. The device is removable from beneath the appliance for carrying to an appropriate place to empty the contents, preferably by tipping the device to drain the liquid through platform corner apertures. The device may be separate from, and not connected to, the appliance, or may be sold as a connected but removable portion of the appliance.
