Abstract
The present invention discloses a folder index pocket structure, comprising a main body for being used in a folder having a plurality of loose-leaf pages, and such main body is a thin plastic transparent plate using a front cover sheet and a back cover sheet on one side of the main body to define an index pocket for holding an index card; a folded edge is disposed at the bottom of the index pocket to receive the index card; and a through hole is disposed on the back cover sheet for letting a user push the index card into and out of the index card pocket by finger. By means of the marked numbers on the index card corresponding to the page number, we can attain the purposes of turning the page and search the content quickly. Furthermore, the index pocket is used to protect the index card, so that the index card has the functions of resisting water and dirt, preventing damages, and saving materials.
Description




FIELD OF INVENTION




The present invention relates to a document folder structure, more particularly to a folder which includes an index pocket for holding an index card and providing reference to the page numbers for quick inquiry of data and contents in the folder. The index card is movably inserted into a through hole of the index pocket to facilitate a user to hold the index card with a finger, so that the user can insert or remove the index card. This invention can also attain the purposes of resisting water and dirt, preventing damages, and saving materials.




BACKGROUND OF THE INVENTION




Please refer to

FIG. 1

for the common folders sold in the market which generally have a label


1


extended from a part of the outer side of the inner page for labeling page numbers, and also providing the information of the contents in the inner page marked with the label


1


. Therefore an index page


2


is provided for us to write words or symbols for the corresponding page numbers, and make remarks on the contents recorded in the inner page, and thus attaining the purpose of turning to our desired page more quickly. However, since most of the index pages


2


are placed at the front page of a plurality of loose-leaf pages to facilitate users to turn to their desired page more quickly, therefore such index page


2


may be smudged or even damaged during the process of turning pages. Furthermore, most of such index pages


2


are made of paper and have no waterproof effect, and the index page


2


is usually used as an advertising paper


3


. Therefore, after the index page


2


is torn away, the advertising paper


3


will generally become a piece of garbage and thus wasting unnecessary material costs.




In view of the foregoing index page


6


which has many shortcomings, the inventor of this invention improved the prior art by performing many experiments and then finally invented this invention.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to overcome the above deficiencies and avoid the existing shortcomings by providing an folder index pocket structure, which comprises a main body for being used in a folder having a plurality of loose-leaf pages, and such main body is a thin plastic transparent plate and has an index pocket on one side of the main body; a folded edge is disposed at the bottom of the index pocket to receive the index card; and a through hole is disposed on the back cover sheet for letting a user push the index card into and out of the index card pocket by a finger. By means of referring to the marked number on the index card for its corresponding page number, we can attain the purposes of turning to the desired page and search for the content more quickly.




Another objective of the present invention is to provide a folder index pocket for inserting an index card, and such folder index pocket is used to protect the index card, so that the index card can have the functions of resisting water and dirt, preventing damages, and saving material costs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to

FIGS. 2 and 3A

which show the folder index pocket structure in accordance with this invention, comprising a main body


30


for being used in a document folder


10


having a plurality of loose-leaf pages


11


, and each loose-leaf page


11


has a label


12


extended from its outer side and each label


12


is colored and numbered in sequence; the main body is a thin plastic transparent plate having an index pocket


20


, and the index pocket


20


forms a hollow envelop by folding the outer edges of the thin plastic plate inward, and using high-frequency thermal pressure to adhere the outer edge


201


downward to stick the outer edges onto the back of the main body


30


. Thus, an index pocket


20


is produced by a two-layered structure with a front cover sheet


21


and a back cover sheet


22


to constitute a hollow envelop. The bottom of the back cover sheet


22


is folded upward to form a folded edge


24


with an appropriate area; a through hole


25


in the longitudinal direction is disposed on the back cover sheet


22


; and an indented edge


28


is disposed at the top edge of the back cover sheet


22


. By means of the design of the foregoing index pocket


20


structure, a paper index card


26


can be inserted into the index pocket


20


, and the index card


26


has the same length with the index pocket


20


. The color block


27


with the same width as the label


12


of the loose-leaf page


11


is printed transversally on the index card


26


, and the color block


27


is marked with a label number corresponding to the number on the label


12


.




Since the index pocket


20


of this invention is a pocket, and has a rectangular through hole


25


on its back cover sheet


22


to facilitate users to insert the soft index card


26


and use a finger to pass through the through hole


25


to push the index card


26


as shown in

FIG. 3

until the index card


26


is completely inserted into the index pocket


20


. On the other hand, if the user wants t replace the index card with a new one, the old index card must be pulled out first, and a finger is used to pass through the through hole


25


to directly touch and push the index card


26


out. Further, an indented edge


28


is disposed at the top of the back cover sheet


22


of the index pocket


20


to facilitate a user to insert the index card


26


into the interior of the index pocket


20


.




Further, in this invention, a folded edge


24


disposed at the bottom of the index pocket is used to hold the bottom of the index card


26


, so that the index pocket can prevent the index card


26


from falling out just as a pocket does.




In addition, the index card


26


in accordance with this invention is inserted into a plastic waterproof index pocket


20


, so that the index card is separated to prevent the index card from being smudged or damaged by accident during the process of turning pages, and such index pocket


20


also provides a waterproof effect. The size of the index card


26


is corresponsive to the index pocket


26


, so that it no longer needs to combine with an advertising sheet (not shown in the figure), and thus effectively saving material costs.




In view of the description above, physical samples according to this invention were made, and tests were passed. The design of such index pocket


20


facilitates users to replace the index card


26


, and the back cover sheet


22


having a through hole


25


facilitates users to push the index card into and out of the index pocket


20


with a finger.




The transversal block


27


on the surface of the index card


26


of this invention can be colored and numbered in corresponsive to the color and number of the label


12


of the loose-leaf page in order to allow users to search for the textual contents in the desired loose-leaf page


11


.




Those skilled in the art will readily recognize that these and various other modifications and changes may be made to the present invention without strictly following the exemplary application illustrated and described herein and without departing from the true spirit and scope of the present invention, which is set forth in the following claims.
