A reusable closure is described which comprises an elongate member molded from a plastics material having memory. The member is formed with a reduced thickness live hinge line extending along its length and leg portions defined on opposite sides of the live hinge line which can be urged towards and away from each other between locked and released positions. An upstanding ear extending along the length of each leg portion has a locking portion adapted to releasably snap into locking engagement with a corresponding locking portion on the other ear in the locked position. Rounded areas join each ear to its respective leg portion. A packaging and storage system using such closures is described, and methods of making such closures by extrusion or injection molding are disclosed.

A reusable closure of the type used for holding sheets of pliable material together, comprising a one-piece elongate member molded from a plastics material, the member being formed with a reduced thickness live hinge line extending along its length, substantially straight leg portions being defined on opposite sides of said live hinge line which are movable towards and away from each other about said live hinge line, said leg portions each having an upstanding ear extending along their lengths, the areas joining said leg portions and ears being rounded, said ears having interengageable locking portions at their free edges which are adapted to snap releasably into locking engagement when said leg portions are urged towards each other; said locking portions comprising lips, one of said lips being of arcuate cross section and having a slanted flat face and the other lip being of substantially circular cross section and having a rounded face positioned so as to initially engage said flat face through sheets of pliable material disposed therebetween when said leg portions are urged towards each other and to slide over said slanted flat face into said locking position, whereby the sheets of pliable material are clamped between said interengaged locking portions to hold the sheets together, each of said ears curving arcuately towards each other at an angle of less than 90 degrees so that when in a closed position, the closure is substantially formed into an A-shape with the ears comprising the base of the A, thereby the closure to close and clamp the closure onto sheets of pliable material for clamping the sheets of pliable material together.
