Abstract

The present invention relates to an expandable packing device applied to a paper holder, a portfolio, a diary, a PP file or the like. The expandable packing device includes a first sheet, a second sheet kept extended from a first edge of the first sheet, a first expandable part disposed between the first sheet and second sheet, a third sheet kept extended from a second edge of the first sheet adjacent to the first edge, a second expandable part disposed between the first sheet and the third sheet, wherein the second sheet and the third sheet are kept spaced with the first sheet and secured with each other, so as to form an expandable holding space with the first sheet.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . An expandable packing device comprising: 
 a first sheet;    a second sheet kept extended from a first edge of said first sheet; a first expandable part disposed between said first sheet and second sheet;    a third sheet kept extended from a second edge of said first sheet adjacent to said first edge;    a second expandable part disposed between said first sheet and said third sheet, wherein said second sheet and said third sheet are kept spaced with said first sheet and secured with each other, so as to form an expandable holding space with said first sheet.    
     
     
         2 . The expandable packing device according to  claim 1  wherein said expandable packing device is a paper holder.  
     
     
         3 . The expandable packing device according to  claim 1  wherein said expandable packing device is a portfolio.  
     
     
         4 . The expandable packing device according to  claim 1  wherein said expandable packing device is a diary.  
     
     
         5 . The expandable packing device according to  claim 1  wherein said expandable packing device is a PP file.  
     
     
         6 . The expandable packing device according to  claim 1  wherein said first expandable part and said second expandable part are formed by means of pressing.  
     
     
         7 . The expandable packing device according to  claim 1  wherein said second sheet and said third sheet are secured to each other by means of hooking.  
     
     
         8 . The expandable packing device according to  claim 7  wherein said second sheet further comprises a hooked opening, said third sheet further comprises a hooking part engaged in said hooked opening.  
     
     
         9 . The expandable packing device according to  claim 7  wherein said second sheet and said third sheet are foldable, so as to form an expandable holding space with each face of said first sheet.  
     
     
         10 . The expandable packing device according to  claim 1  wherein said second sheet and said third sheet are secured to each other by means of hot pressing.  
     
     
         11 . The expandable packing device according to  claim 1  wherein said first sheet, said second sheet, said third sheet, said first expandable part and said second expandable part are of a unity.  
     
     
         12 . An expandable packing device comprising: 
 a first sheet;    a second sheet kept extended from a first edge of said first sheet;    a third sheet kept extended from a second edge of said first sheet opposite to said first edge;    a fourth sheet kept extended from a third edge of said first sheet;    a first expandable part disposed between said first sheet and second sheet;    a second expandable part disposed between said first sheet and third sheet; and    a third expandable part disposed between said first sheet and fourth sheet, wherein said second sheet, said third sheet and said fourth sheet are kept spaced with said first sheet, and said second sheet and said third sheet are simultaneously secured with said fourth sheet, so as to form an expandable holding space with said first sheet.    
     
     
         13 . The expandable packing device according to  claim 12  wherein said expandable packing device is used in a paper holder.  
     
     
         14 . The expandable packing device according to  claim 12  wherein said expandable packing device is a portfolio.  
     
     
         15 . The expandable packing device according to  claim 12  wherein said expandable packing device is a diary.  
     
     
         16 . The expandable packing device according to  claim 12  wherein said expandable packing device is a PP file.  
     
     
         17 . The expandable packing device according to  claim 12  wherein said first expandable part, said second expandable part and said third expandable part are formed by means of pressing.  
     
     
         18 . The expandable packing device according to  claim 11  wherein said second sheet and said third sheet are secured by means of hooking.  
     
     
         19 . The expandable packing device according to  claim 18  wherein said fourth sheet further comprises plural hooked openings, said second sheet and said third sheet further respectively comprises plural hooking parts respectively engaged in said hooked openings.  
     
     
         20 . The expandable packing device according to  claim 12  wherein said second sheet and said third sheet are secured to said fourth sheet by means of hot pressing.  
     
     
         21 . The expandable packing device according to  claim 12  wherein said first sheet, said second sheet, said third sheet, said fourth sheet, said first expandable part, said second expandable part and said third expandable part are of a unity.  
     
     
         22 . An expandable packing device comprising: 
 a first sheet;    a second sheet kept extended from a first edge of said first sheet;    a third sheet kept extended from a second edge adjacent to said first edge of said first sheet;    a first expandable part disposed between said first sheet and second sheet;    a fourth sheet kept extended from a third edge of said first sheet;    a fifth sheet kept extended from a fourth edge of said first sheet;    a second expandable part disposed between said first sheet and third sheet, wherein said second sheet and said third sheet are kept spaced with said first sheet and secured with each other, so as to form an expandable holding space with said first sheet;    a third expandable part disposed between said first sheet and fourth sheet; and    a fourth expandable part disposed between said first sheet and fifth sheet, wherein said fourth sheet and said fifth sheet are kept spaced with said first sheet and secured with each other, so as to form an expandable holding space with said first sheet.
