Claim Text:
1. An adjustable, automatically enlarging loop forming apparatus for an object with an flexible opening, said apparatus comprising: an elongated flexible band having a first end, a second end opposite said first end, an inner surface and an outer surface, said flexible band configured so that when said second end slides under and overlaps said first end a closed loop is formed, said flexible band is made of material that enables it to form different size closed loops by manually forcing said second end under said first end and sliding said outer surface of said flexible band adjacent to said second end and against said inner surface of said flexible band adjacent to said first end, said flexible band expands and automatically returns to its original shape and increases the diameter of said closed loop when the manual force is removed; a catch aperture formed near said first end of said flexible band, said catch aperture configured to receive said second end of said flexible band and allows said second end to slide under said first end and keep said flexible band configured in a closed loop, said catch aperture includes a transversely aligned front edge and a transversely aligned rear edge, said catch aperture configured to receive said second end of said flexible band when said second end extends over said first end and slides under said inner surface of said flexible band to form a said closed loop; a catch ridge located on said inside loop surface of said flexible band near said second end, said catch ridge configured to abut said rear edge of said catch aperture when said second end is inserted into said catch aperture, said catch ridge located inward from said second end of said flexible strap so that when said flexible band expands and returns to its original shape, said second end slides outward through said catch aperture and said catch ridge abuts said rear edge of said catch aperture and prevents said second end from disengaging from said catch aperture; and, wherein when said second end of said flexible band is inserted into said catch aperture and manually forced inward to form a narrow closed loop and then placed inside an opening formed on a flexible object and said second end is released, said flexible band automatically expands forcing the flexible opening on said object to expand to allow air to enter said object whereby airflow is enhanced.
