Abstract
The invention relates to a stackable tray comprising an outer sheet with foldable tabs that fold around an inner sheet, and columns glued to the inner sheet. The outer sheet is glued to the columns and the tabs are glued to the inner sheet. The folder is the same tray but with an added cover glued to the left side of the tray. The trays or folders can be stacked one on top of the other, the inner sheet being supported on the columns, the columns being supported one on top of the other. The trays have side labels that allow them to be identified from the side when they are stacked, and a front label that allows the cover to be identified in the case of a folder.

DETAILED DESCRIPTION OF THE INVENTION
[0021] FIG. 1. Is a perspective view of the tray with the outer sheet 1 folded, the inner sheet 2 and the side label 4. The tabs 7 are glued to the inner sheet 2.
[0022] FIG. 2. Is a perspective view of the folder with the outer sheet 1 folded, the inner sheet 2 and the side label 4. The tabs 7 are glued to the inner sheet 2. The cover 3 is glued to the left side of the tray, the cover 3 has a fold line 3A to open and close the cover 3 and also has a front label 5 to identify the file.
[0023] FIG. 3. Is a plan view of the outer sheet 1 without folding with the folding tabs 7, 8, 9, 10. The size of the folding tabs 8,10 will vary depending on the height of the tray or folder, the higher the tray or folder, the wider the folding tabs 8,10 will be. The outer sheet 1 could be made of manila paper, kraft paper, thin cardboard (cardboard), glossy cardboard, cardboard, plastic or any other material that can be folded and offers protection to the documents.
[0024] FIG. 4. Is a plan view of the inner sheet 2 with the columns 15,16. The distance L26 will be 8.5 inches plus a slight clearance for letter and legal size trays and folders. The distance L27 will be 11 inches plus a small clearance for letter-size trays and binders. The inner sheet 2 could be made of gray cardboard, kraft cardboard, corrugated cardboard or any other material that offers resistance to deflection, to support the weight of the documents.
[0025] FIG. 5. Shows a perspective view of the unfolded outer sheet 1, the inner sheet 2, the distribution of the columns 15,16 and the fold lines 8A,9A,10A,7A of the folding tabs. In this view, the complete assembly process of the tray can be interpreted, first the columns 15,16 are glued to the inner sheet 2, then the folding tabs are folded along the fold lines 8A,9A,10A,7A and glued to the columns 15,16 and finally the tabs 7 are glued to the inner sheet 2. This same procedure will be used to assemble the trays and folders of different sizes and heights, for the different sizes of documents, letter, legal, tabloid etc.
[0026] FIG. 6. Is a perspective view of the hollow 15,16 and solid 17,18, square and L-shaped columns. These columns 15,16,17,18 serve as support so that the trays or folders do not collapse when they are stacked one on top of the other. The height of the columns 15,16,17,18 will depend on the height that the folder is to be manufactured. The hollow columns 15,16 and solid 17,18, square and in L, could be made of cardboard, pressed wood, wood, plastic or any other material that offers resistance to compression, so that the trays or folders are not squashed when stacked on top of each other.
[0027] FIG. 7. Is a perspective view of the side label 4 and the label holder 4A. The side label 4 could be made of paper and stick to the folder or tray. The tray or folder may or may not have a label holder 4A to insert a label into it so that it can be changed if desired.
[0028] FIG. 8. Is a plan view of the cover 19 with flanges 19B. The tabs 19B are to seal the folder with glue if required. The fold line 19A is for opening and closing the cover 19.
[0029] FIG. 9A. Is a plan view of the unfolded outer sheet 14A, the inner sheet 14B and the distribution of the columns 15,16 of the tray to contain legal-size documents.
[0030] The distance L26 will be 8.5 inches plus a slight clearance for legal size trays and binders. The distance L28 will be 14 inches plus a small clearance for legal size trays and binders.
[0031] FIG. 9B. Is a plan view of the folded outer sheet 14A and inner sheet 14B of the tray for holding legal-size documents. The tabs 7 are glued to the inner sheet 14B.
[0032] FIG. 10. Shows a perspective view of the folders 25,26,27,28,29,30 of different heights, stacked one on top of the other and with the side labels 4,20. The folder 25 could be ⅛ inch high. The folder 26 could be ¼ inch high. The folder 27 could be ½ inch high. The folder 28 could be 1 inch high. The folder 29 could be 1.5 inches high. The folder 30 could be 2 inches high.
[0033] FIG. 10A. Shows a sectional view of the folders 25,26,27,28,29,30 of different heights, stacked one on top of the other. In this view it can be seen that the inner sheet 2 is supported on the columns and the columns are supported one on top of the other.
The thickness of the inner sheet 2 will vary depending on the number of sheets 21 that it has to support, this thickness must be that required so that the inner sheet 2 can support the sheets 21 without being deflected or the deflection due to the load of the leaves 21 is minimal.
[0034] FIG. 10B. Shows an elevation view of the folders 25,26,27,28,29,30 of different heights, stacked one on top of the other and with the side labels 4.
