Definitions

  • This invention relates to folders for filing papers, documents and the like, and more particularly, to a plastic file folder which is flexible, durable and economical to manufacture.
  • File folders have been well known for many years and typically are made of a suitable fibrous material, such as fiberboard or paperboard.
  • U.S. Patent No. 2,291,724 describ ⁇ es a filing folder having a V-shaped pocket for receiving papers and documents and is provided with hanging hooks at the free edges for hanging or suspending the file folder.
  • Such folders have the drawback that they require separate steps to manufacture the parts and assemble them, making them more costly to manufacture than a file folder which would require no assembly and could be formed in a one-step operation. Also, because they are formed from a fibrous material, they are not longlasting and. are not durable.
  • a one-piece injection molded plas ⁇ tic file folder having first and second panels which define a V-shaped pocket therebetween.
  • a transversely extending hinge is formed between the first and second panels to allow the panels to fold relative to each other.
  • the hinge may include plural creases to allow for different size pockets.
  • the panels are injection molded from plastic to have an open framework, preferably in the form of an open grid.
  • the grid includes horizontal and vertical ribs which form rectangular-shaped openings to reduce the weight and cost of the product.
  • the open framework or grid may be formed to have triangular-shaped openings, diamond-shaped openings, circu ⁇ lar-shaped openings, or any equivalent arrangement which lends itself to injection molding techniques.
  • the panels may also be provided with label-receiving means, paper-receiving clips, carrying handles and snap means for releasably locking the panels to each other.
  • the present invention provides a file folder capable of high yield and economical production.
  • the plastic file folder can be injection molded in one opera ⁇ tion as a one-piece unit and thus needs no assembly opera- tion. Further, the plastic file folder is economical enough to replace paperboard file folders and is more durable to wear and tear, and thus has a longer useful life.

Similarly, panel 14 includes horizontal ribs 14b and verti ⁇ cal ribs 14c which define square-shaped openings 14d. The border or entire periphery of each panel 12 and 14 is provided with widened areas 12e and 14e of solid plastic, which surround the grid openings, and increase the rigidity of the folder 10.
  • outer borders 20 and 22 are each provided with integrally formed ribs or protrusions 20c and 22c, respectively.
  • ribs 20c and 22c may be placed at different heights on the borders so that they will nest when two or more folders are laying against each other.
  • FIGs. 2 and 2a there is shown an alternative arrangement for reinforcing the outer borders of panels 12 and 14.
  • border 20' is reinforced by molding a V-shaped cross section 20d into the border.
  • border 22' is provided with a similar V-shaped cross section 22d.
  • an integrally-formed folding hinge 18 which is formed by a crease or score 18a of reduced thickness (see Fig. 3).
  • several scores may be formed in the hinge area 18 so that the thickness or width at the bottom of pocket 16 may be increased for additional documents.
  • several scores 18b, 18c and 18d are provided for increasing the width of the pocket.
  • the thickness of the plastic in each panel is preferably forty-thousandths of an inch (0.040"), but can vary from twenty to sixty-two-thousandths of an inch.
  • the score lines 18a, 18b, 18c, and 18d have a reduced thickness in the range of two to ten-thousandths of an inch, but the preferred thickness of the score lines is four-thousandths of an inch (0.004").
  • a border or solid hanging strip 20 having integrally formed on one end of the strip a hook 20a, and integrally formed on the other end a hook 20b.
  • a border or solid hanging strip 22 having integrally formed on one end of the strip a hook 22a and integrally formed on the other end of the strip a hook 22b.
  • the hooks are for the purpose of hanging a file folder in a drawer or the like, in a manner known in the prior art.
  • a label receiving slot 24 may be integrally formed on one or both of the hanging strips 20 and 22.
  • the slot 24 includes three L-shaped channels for slidably receiving a suitable file label or marker.
  • Alternate label receiving means are shown in Figs. 8 and 9.
  • Fig. 8 shows a rectangular frame 28 having spokes 29 for receiving tabs which are weaved through the spokes and removably held in place by them.
