A continuous, relatively stiff ring capable of being coiled to form at least a pair of adjacent, generally circular loops of substantially the same size, about which the mouth of a flexible bag may be tucked as the loops are rolled over one another several times to, in turn, cause the bag mouth to be rolled a number of times about the loops and to be captured thereby, so that the loops hold open the bag mouth.

Apparatus comprising: a flexible bag having a mouth portion; and an endless member defining a continuous ring coiled to form at least two adjacent and overlapping, generally circular loops adapted to receive said bag mouth, the bag mouth being wrappable about the loops when the loops are rolled about each other a number of times to releasably couple the bag mouth to the member, said member provided with sufficient rigidity so that said bag mouth is held in an open position.
