Abstract
A refuse compactor device has a container housing having an open top end for holding a trash bag in which the bag mouth is in registration with and folded over the open top end of the container for receiving trash to be compacted. The compactor device further includes a compactor plate received within the container housing for manual movement from the open top end of the housing toward the bottom end of the housing to compress refuse material in the trash bag. The housing has ventilation apertures in its side wall and bottom to allow air trapped between the bag and the side walls of the housing to be expelled from the container. The compactor plate also has ventilation apertures to allow air included in the refuse to be expelled from the container as the plate is moved into the trash bag and housing. The compactor plate further has an opening to receive therethrough the mouth end of the bag for convenient closing of the bag mouth.
