An article closure includes a crushable channel, a crushable portion, and a stretchable cord in the channel with a protruding end. A releasable closure restricts movement of the cord. Pressure on the end of the cord extends it, and moves a portion thereof through the closure. Upon release the stretched portion of the cord within the channel crushes the channel as it contracts toward its unstretched length, thereby shortening the length of the channel and the crushable portion. On release of the closure, a portion of the cord moves back toward the channel and allows the channel and the portion of the article to which the channel is attached to return to their uncrushed dimensions. Retaining straps hold the closure to the article proximate the opening in the channel so that the closure is restricted from moving away from the opening in the channel. |
