Methods and devices for improved materials storage

A plug device for snugly and releasably sealing material within a container when the plug device is inserted into the container, the plug device comprising:

• a plug body that is sized to be positioned within the container for releasably sealing material into the container and for covering a top surface of the material,
• wherein the plug body has sufficient flexibility for at least partially folding the plug body, and
• a plug handle section having a plurality of handles for holding the plug device, for manipulating the plug device into and out of the container, for facilitating insertion of the plug body into the container and removal of the plug body from the container, and for deforming the plug body out of an unfolded state, the plurality of handles comprising:
• a first handle having a first handle beginning, a first handle end, and a first handle portion extending therebetween,
• wherein the first handle beginning and the first handle end are attached to the plug body at or near opposite ends of a first diameter across the plug body, and
• wherein the first handle portion is unattached to the plug body, except through the first handle beginning and the first handle end, and extends above the plug body along the first diameter;
• and
• a second handle having a second handle beginning, a second handle end, and a second handle portion extending therebetween,
• wherein the second handle beginning and the second handle end are attached to the plug body at opposite ends of the plug body at or near opposite ends of a second diameter across the plug body, and
• wherein the second handle portion is unattached to the plug body, except through the second handle beginning and the second handle end, and extends above the plug body along the second diameter;
• and
• wherein the second diameter is offset from the first diameter.
