Abstract

A sleeve for holding papers or other material may be provided with an outer corner tab. The sleeve may be formed of a single die-cut sheet of plastic or other material, or from two or more sheets that are attached together. A first sheet may include score lines along two adjacent edges that enable an extended portion of the first sheet to be folded over a second sheet. The second sheet may include score lines that enable an outer corner tab to be formed thereon. The corner tab enables a portion of the papers or other material stored in the sleeve to be inserted into an insert space of the tab. The tab may then be used to retain papers in a secure manner, such that they will not fall out of the sleeve should the sleeve or folder be inverted.

Claims

1. A document sleeve having a corner tab comprising:

a front cover having a free upper corner;

a back cover;

a corner tab on an upper corner of the back cover;

said front cover and said back cover being interconnected along the two adjacent edges opposite said corner tab;

said corner tab providing an insert space for said free corner of said front cover to secure said free corner of said front cover within said corner tab.

2. A document sleeve as described in claim 1, wherein the front cover and back cover comprise separate sheets of material attached together along said two adjacent edges.

3. A document sleeve as described in claim 2, wherein one of said front cover and said back cover comprise foldable extended portions on two adjacent sides of the sheet for securing the front cover to the back cover.

4. A document sleeve as described in claim 1, wherein the document sleeve is a high-capacity sleeve, with the corner tab comprising a top surface, two side walls and a bottom surface, said insert space being defined by said top and bottom surfaces and said side walls.

5. A document sleeve as described in claim 1, wherein the document sleeve is a high-capacity sleeve, said sleeve comprising a top surface, two adjacent side walls and a bottom surface.

6. A document sleeve as described in claim 5, wherein the high-capacity sleeve is formed from two separate sheets of material.

7. A document sleeve as described in claim 1, wherein said front cover, back cover, and corner tab are unitarily formed from a single sheet of material.

8. A document sleeve as described in claim 1, wherein the corner tab is initially separate from said front cover and back cover, and is then attached to said back cover.

9. A document sleeve as described in claim 8, wherein the corner tab is attached by heat welding, sonic welding or gluing.

10. A document sleeve having a corner tab comprising:

a front cover having a free upper corner;

a back cover;

a corner tab on an upper corner of the back cover;

said front cover and said back cover being interconnected along the two adjacent edges opposite said corner tab;

said corner tab providing an insert space for said upper corner of said front cover;

wherein the corner tab comprises a top corner tab surface and a separator, said insert space being defined by said top corner tab surface and said separator; and

said front cover and said back cover being interconnected along said two adjacent edges, each with a respective side wall, said front cover, back cover and side walls defining a document-retaining space.

11. A document sleeve as described in claim 10, wherein said document-retaining space is sufficiently wide to accommodate at least 50 sheets of paper.

12. A document sleeve as described in claim 10, wherein the sleeve is formed from two separate sheets of material joined along two respective edges thereof.

13. A document sleeve as described in claim 12, wherein said two separate sheets are different materials.

14. A document sleeve as described in claim 10, wherein said front cover, back cover, and corner tab are unitarily formed from a single sheet of material.

15. A document sleeve as described in claim 10, wherein the corner tab is initially separate from said front cover and back cover, and is then attached to said back cover.

16. A document sleeve as described in claim 15, wherein the corner tab is attached by at least one of heat welding, sonic welding or gluing.

17. A document sleeve having a corner tab comprising:

a front cover having an interior and an exterior;

a back cover having an interior and an exterior;

a corner tab on an upper corner of the interior of the back cover, with a corner tab insert space in between the corner tab and the back cover;

said front cover and said back cover being interconnected along two adjacent sides opposite said corner tab, said front cover having a free upper corner;

a document retention space in between said front cover and said back cover, at least one side adjacent to said corner tab being open to said document retention space;

wherein the corner tab insert space is adapted to receive said free corner of the front cover.

18. The document holder of claim 17, wherein said document sleeve comprises a polymer.

19. The document holder of claim 17, wherein said corner tab extends along portions of two adjacent sides of said sleeve to retain said free corner of said front cover along two sides.

20. A document sleeve as described in claim 17, wherein the front cover and back cover comprise separate sheets of material attached together along said two adjacent edges.

21. A document sleeve as described in claim 17, wherein the document sleeve is a high-capacity sleeve, with the corner tab comprising a top surface, two side walls and a bottom surface, said two adjacent side walls creating an insert space between said top and bottom surfaces.

22. A document sleeve as described in claim 17, wherein the document sleeve is a high-capacity sleeve, said sleeve comprising a top surface, two adjacent side walls and a bottom surface, said two adjacent side walls creating a space between said top surface and said bottom surface.

23. A document sleeve as described in claim 21, wherein the high-capacity sleeve is formed from two separate sheets of material.

24. A document sleeve as described in claim 21, wherein said front cover, back cover, and corner tab are unitarily formed from a single sheet of material.

25. A document sleeve as described in claim 21, wherein the corner tab is initially separate from said front cover and back cover, and is then attached to said back cover.

26. A document sleeve as described in claim 25, wherein the corner tab is attached by heat welding, sonic welding or gluing.

27. A document sleeve comprising:

a front cover having a free corner;

a back cover;

said front cover and said back cover being attached along two adjacent edges to form a sleeve;

means for securing said free corner of said front cover to said back cover.

28. A document sleeve as defined in claim 27, wherein said sleeve further comprises means for accommodating at least 50 sheets of paper between said front cover and said back cover.

29. A document sleeve as defined in claim 27, wherein said means for securing said free corner of said front cover to said back cover can accommodate at least 50 sheets of paper.
