Abstract: A trash receptacle including a container having a variable upper periphery to hold the opening of a plastic trash bag in tension and to ease the removal of a full bag of trash from the container. In one embodiment, the container has a peripheral frame having spaced apart ribs or protrusions, a slider bar mating with the spaced apart protrusions, a spring disposed intermediate the frame the slider bar to urge the slider bar away from the frame, thereby holding a plastic trash bag in a secure and open position within the trash receptacle. In another embodiment, a vertical section of the container is biased away from the main body of the container by gravity or springs. Thus, when the bag is placed within the container and wrapped around the lip of the container, the upper periphery of the vertical section is biased away from the upper periphery of the main body to hold the opening of the trash bag in tension.
