Abstract

A binder including a front cover including a front cover exterior layer, a front cover interior layer, a front cover base plate between the front cover exterior layer and the front cover interior layer, an exterior pocket formed between the front cover exterior layer and the front cover base plate, and an interior opening formed through the front cover interior layer and the front cover base plate to the exterior pocket. Methods of manufacturing the binder are also disclosed.

First claim

What is claimed is:

1. A method of manufacturing a binder, the method comprising:
providing:
an interior polymer layer;
an exterior polymer layer; and
a foamed polymer layer;

cutting:
the interior polymer layer to form a single continuous interior layer including a front cover interior layer, a spine interior layer, and a back cover interior layer;
the interior polymer layer to form an interior opening through the front cover interior layer, a front cover interior opening through the front cover interior layer, a spine interior opening through the spine interior layer, and a back cover interior opening through the back cover interior layer;
the exterior polymer layer to form a single interconnected exterior layer including a front cover exterior layer, a spine exterior layer, and a back cover exterior layer;
the foamed polymer layer to form a front cover base plate;
the foamed polymer layer to form an interior opening through the front cover base plate; and
the foamed polymer layer to form a back cover base plate;

stacking:
the front cover base plate between the front cover interior layer and the front cover exterior layer; and
the back cover base plate between the back cover interior layer and the back cover exterior layer; and
sealing at least a portion of the single continuous interior layer and a portion of the single interconnected exterior layer together.

2. The method of claim 1 , wherein the step of the sealing at least a portion of the single continuous interior layer and a portion of the single interconnected exterior layer together includes Radio Frequency (RF) welding, heat sealing, or ultrasonic welding.

3. The method of claim 2 , wherein the step of the sealing at least a portion of the single continuous interior layer and a portion of the single interconnected exterior layer together forms a seal area and a bumper bead, the seal area has a width in a range of about 0.5 mm to about 1.5 mm, and the bumper bead has a width in a range of about 0.5 mm to about 1.5 mm.

4. The method of claim 3 , wherein the interior opening formed through the front cover interior layer includes a peripheral edge, the front cover interior opening formed through the front cover interior layer includes a peripheral edge, the spine interior opening formed through the spine interior layer includes a peripheral edge, and the back cover interior opening formed through the back cover interior layer includes a peripheral edge, and further comprising at least one of:
embossing the peripheral edge of the interior opening formed through the front cover interior layer;
embossing the peripheral edge of the front cover interior opening formed through the front cover interior layer;
embossing the peripheral edge of the spine interior opening formed through the spine interior layer; and
embossing the peripheral edge of the back cover interior opening formed through the back cover interior layer.

5. The method of claim 1 , further comprising:
stacking a spine panel between the spine interior layer and the spine exterior layer;
stacking a spacer between the spine interior layer and the spine panel;
sealing at least a portion of the spine interior layer and a portion of the spine exterior layer together; and
removing the spacer through the spine interior opening formed through the spine interior layer.

6. The method of claim 5 , wherein the step of sealing the portion of the single continuous interior layer and the portion of the single interconnected exterior layer together and the step of sealing the portion of the spine interior layer and the portion of the spine exterior layer together are performed concurrently.

7. The method of claim 1 , further comprising forming a first hinge and a second hinge a portion of the single continuous interior layer and a portion of the single interconnected exterior layer.

8. The method of claim 7 , wherein the first hinge includes at least two columns of ridges.

9. The method of claim 8 , wherein the second hinge includes at least two columns of ridges.

10. The method of claim 9 , wherein the ridges of the at least two columns of ridges of the second hinge are diagonal ridges.

11. The method of claim 9 , wherein the ridges of the at least two columns of ridges of the second hinge are vertical ridges.

12. The method of claim 9 , wherein the ridges of the at least two columns of ridges of the second hinge are horizontal ridges.

13. The method of claim 8 , wherein the ridges of the at least two columns of ridges of the first hinge are diagonal ridges.

14. The method of claim 8 , wherein the ridges of the at least two columns of ridges of the first hinge are vertical ridges.

15. The method of claim 8 , wherein the ridges of the at least two columns of ridges of the first hinge are horizontal ridges.

16. The method of claim 8 wherein the columns of ridges of the first hinge and the second hinge each include a plurality of valleys between the respective ridges of each column of ridges.

17. The method of claim 7 , wherein the step of forming the first hinge and second hinge includes sealing the exterior layer to the interior layer.
