Abstract: A closure member for a bag has a blade and a sheath. The sheath has side walls that are joined on inner edges and open on outer edges. The blade inserts between the side walls. A partition connects between the side walls near a locking end of the sheath. The partition has a shoulder. A retaining wall locates on the locking end of the sheath, spaced longitudinally from the partition. The blade has a locking member that will insert between the retaining wall and the partition. The locking member of the blade has a shoulder that snaps over the shoulder end of the retaining wall.
Abstract: A Thermal Pack is shown for use in treating a localized injury. The pack includes a porous outer bag and a non-porous inner bag which is foldable between a retracted position within the outer bag and an extended position in which the inner bag protrudes from the outer bag for filling. A flap extends from the open mouth of the inner bag for creating a funnel to facilitate filling the inner bag when the inner bag is in the extended position.
