Claim 17:
18. A flexible structure configured to expand a collapsible flask, the flexible structure comprising:
a first loop made of an elastically flexible material;
a second loop made of an elastically flexible material; and
a tether;
wherein:
the first loop and the second loop are operatively coupled together at a first intersection and second intersection;
the tether comprises:
a first end coupled to the first loop and the second loop at the first intersection; and
a second end coupled to the first loop and the second loop at the second intersection; and

the first loop and the second loop, together, are elastically movable between a compressed configuration in which the tether is slack and the first loop and the second loop are sufficiently narrow to fit through an opening of the collapsible flask, and an expanded configuration in which the tether is tensioned and the first loop and the second loop are not sufficiently narrow to fit through the opening.
