File folder

Abstract

A file folder has a faceplate, at least a snap-type combined plate and snap holes. The snap-type combined plate is snapped securely onto a local position of the faceplate. The snap-type combined plate has a first and a second snapping plate and coupling portion. The first and second abutting surfaces are formed separately on the first and second snapping plates for abutting onto two side surfaces of the faceplate. The first and second snapping plates are aligned correspondingly. The coupling portion allows secure coupling of the first and second snapping plates. Of which, the faceplate and snap-type combined plate are made of different materials. On the whole, the file folder of the present invention provides a protective effect, extends the service life and improves the assembly or recycling efficiency with better industrial benefits and applicability.

1 . A file folder comprising:
 a faceplate having a middle faceplate, a first and second side faceplate connected at both sides of the middle faceplate; of which, there is a folding line between the first/second side faceplates and middle faceplate, such that the first/second side faceplates can be folded in relation to the middle faceplate; and a corner is defined onto the first/second side faceplates of the faceplate, whilst a flange is defined onto the middle faceplate;   at least a snap-type combined plate, snapped securely onto local position of the faceplate; said snap-type combined plate comprising:
 a first snapping plate having a first abutting surface for abutting onto the side surface of the faceplate; 
 a second snapping plate having a second abutting surface for abutting onto the other side surface of the faceplate; the second snapping plate is aligned correspondingly with the first snapping plate; 
 at least a coupling portion, allowing to couple securely the first and second snapping plates; 
 snap holes; set correspondingly onto the faceplate for assembly of snap-type combined plate; the snap holes penetrate two side surfaces of the faceplate, allowing for insertion of the coupling portion of the snap-type combined plate; 
 of which, the faceplate and snap-type combined plate are made of different materials. 
   
     
     
         2 . The structure defined in  claim 1 , wherein said snap-type combined plate is assembled at the corner of the first and second side faceplates, such that the first and second snapping plates are structured into L-shaped pattern. 
     
     
         3 . The structure defined in  claim 1 , wherein said snap-type combined plate is assembled at the flange of the middle faceplate, such that the first and second snapping plates are structured into extended pattern. 
     
     
         4 . The structure defined in  claim 1 , wherein said snap-type combined plate is assembled at the folding line defined by the first/second side faceplates and middle faceplate; so the snap-type combined plate comprises of a first retaining portion, a second retaining portion and a folding edge between the first and second retaining portions, such that the first and second side faceplates can be folded, and the first/second snapping plates are arranged along the extension of the faceplate. 
     
     
         5 . The structure defined in  claim 1 , wherein a coupling edge is set between the first and second snapping plates, and used to connect the first and second snapping plates. 
     
     
         6 . The structure defined in  claim 1 , wherein the coupling portion is composed of male and female snappers that are protruded separately from the corresponding positions of the first/second abutting surfaces of the first/second snapping plates. 
     
     
         7 . The structure defined in  claim 1 , wherein said coupling portion is combined with the first and second snapping plates; assembly holes are set correspondingly onto the first/second abutting surfaces of the first/second snapping plates for the coupling portion.
