Binding system

A one piece plastic binder, that can be opened and closed so that when the binder is closed it has a generally circular cross section and articles having holes located near one edge of the articles are contained, comprising:

• a. an elongated section with a living hinge having two hinge extensions;
• b. a first plurality of spaced apart substantially semicircular shaped ribs, the ribs having a distal end and a proximal end with the proximal end integrally formed onto one hinge extension, the first plurality of ribs further having a length such that when the binder is closed the distal end of the ribs substantially abuts the other hinge extension;
• and
• c. a second plurality of spaced apart substantially semicircular shaped ribs, the ribs having a distal end and a proximal end with the proximal end integrally formed onto the other hinge extension, the second plurality of ribs being opposite to and corresponding in location with the first plurality of ribs such that when the binder is closed, the second plurality of ribs is above the first plurality of ribs, the second plurality of ribs further having a length such that when the binder is closed the second plurality of ribs substantially overlap the first plurality of ribs and when the binder is in an open position, the distal end of the second plurality of ribs contacts the first plurality of ribs, wherein the binder can be opened by bending one end of the hinge toward the other end of the hinge.

A one piece binder comprising:

• a. an elongated section with a living hinger having two hinge extensions:
• b. a first cover integrally formed onto a first hinge extension and extending substantially the length of the hinge;
• c. a second cover integrally formed onto a second hinge extension, the length of the second cover being substantially the same as the first cover;
• d. a first plurality of spaced apart ribs, the ribs having a distal end and a proximal end with the proximal end integrally formed onto the first hinge extension;
• and
• e. a second plurality of spaced apart ribs, the ribs having a distal end and a proximal end with the proximal end integrally formed onto the second hinge extension, the second plurality of ribs being opposite to and corresponding in location with the first plurality of ribs, wherein the hinge, the hinge extensions and the ribs, when in a closed position, have a generally circular cross section.
