ABSTRACT:
A method and device for retaining, in a rolled-up configuration, a portion of a collapsible container that holds a quantity of a product. The method includes forming a roll of a collapsible container holding a quantity of a product. The opening of a U-shaped clip is then urged into engagement with the roll of the collapsible container until the opening passes about the roll, and the roll becomes disposed between arms of the U-shaped clip. Thus arranged, an layer of a resilient, open-cell foam material lining the inside of the U-shaped clip is juxtaposed with and compressed by the roll of the collapsible container.
