Flexible closure

A flexible closure comprising:

• a series of at least two flexible stiffening flanges;
• said flexible stiffening flanges being lined up like rungs on a ladder;
• said rung-like flexible stiffening flanges being attached at two ends by two attachment regions;
• said attachment regions being perpendicular to said rung-like flexible stiffening flanges, and appearing like sides of a ladder that support rungs of a ladder;
• said rung-like flexible stiffening flanges and said attachment regions forming a ladder-like structure;
• said ladder-like structure being oriented in a vertical manner and said rung-like flexible stiffening flanges moving horizontally in groups of at least one away from the centerline of said ladder-like structure to form an opening;
• said groups of rung-like flexible stiffening flanges forming two sets on opposing sides of said opening;
• and
• said sets of groups of rung-like flexible stiffening flanges moving towards each other to close the closure.

A closure comprising:

• a series of at least two flexible bar-like portions;
• said flexible bar-like portions being oriented in groups of at least one to one side then to the other side of an opening between them;
• said groups comprising two sides of said opening,
• said opening being oval, circular or eye shaped when opened,
• said two sides moving towards each other as said opening closes;
• said flexible bar-like portions having ends connected together and comprising a hingeline having two corners that coincide with said ends of said flexible bar-like portions making up said groups comprising said two sides of said opening;
• and
• said sides nesting against each other when said closure is closed.
