A plug device is disclosed for snugly sealing material within a container. The plug device has a flexible, foldable, deformable plug body sized to be positioned within the container. The plug device also has a plug handle section with handles for facilitating insertion and removal of the plug body and for deforming the plug body out of an unfolded state. A first handle is attached to the plug body at both its beginning and end and along a radial axis of the plug body. A second handle, offset from the first handle, is also attached to the plug body at both its beginning and end and along the radial axis. The handles may be manipulated to deform the plug body out of an unfolded state. The manipulation, which may be twisting, squeezing, or using a tool, facilitates insertion of the plug body into the container and removal from the container.
