Abstract
A first panel-like element has a longitudinal fold near a first longitudinal edge. A second panel-like element has a longitudinal crease near a second longitudinal edge. The first longitudinal edge and second longitudinal edge are parallel to each other and form a longitudinal opening. A fastener is disposed at said longitudinal opening. When the fastener of the closure is closed, the first element and a second element form a flat, longitudinal flap, and the longitudinal opening and the fastener are located on the inside surface of the flap.
