Abstract
Disclosed is a plate cover system having a plurality of plate covers that can be configured to stack upon each other in a protracted configuration and/or or a collapsed configuration. In one embodiment, a first plate cover can be used to support a second plate cover by placing the second plate cover on top of the first plate cover, wherein a volume of space exists between the first plate cover and the second plate cover. The system can be transitioned between the protracted configuration and the collapsed configuration by slidably engaging channels disposed on sidewalls of the plate covers. Some embodiments include a rotation retention mechanism for securing the plate covers in place when in a protected or a collapsed configuration.
