A refastenable mechanical fastening system has built-in elasticity and stretchability. The fastening system includes a first member provided with engaging elements and a second member consisting of a stretchable elastic tab having opposite end portions. One end portion of the elastic tab is secured to one of the objects to be fastened. The free end portion of the elastic tab extends from the object. The first member of the attachment system, which consists of engaging elements, is secured to the second object to be fastened. The two objects are fastened together by extending the elastic tab to engage the engaging elements of the first member. The stretchable elastic tab provides freedom for adjustment of the spatial relation between the two secured objects. One application of this invention is to provide a flexible closure system for a disposable diaper. |
