Packaging device

Abstract

The packaging device contains a first frame member for wrapping a first edge of a frame, a second frame member for wrapping a second edge of the frame, at least a positioning opening configured in a middle section of each first and second frame member, and at least a plugging element configured at an end of each first and second frame member for joining with a positioning opening of another frame member. The frame members not only provide protection to the frame, but also help positioning the frame and maintaining a standard distance when the frame is hung.

I claim: 
     
         1 . A packaging device for a frame of a painting or picture comprising:
 at least a first frame member for wrapping a first edge of the frame;   at least a second frame member for wrapping a second edge opposing the first edge of the frame;   at least a positioning opening configured in a middle section along a side of each first and second frame member; and   at least a plugging element configured at an end of each first and second frame member for joining with a positioning opening of another frame member;   wherein, after the first and second frame members are joined by their respective positioning opening and plugging element, an assembly formed by the first and second frame members is used to help positioning the frame.   
     
     
         2 . The packaging device according to  claim 1 , wherein each frame member comprises at least a major face protecting a front or back face of an edge of the frame. 
     
     
         3 . The packaging device according to  claim 2 , wherein each frame member comprises a supporting face between two opposing major faces protecting a rim of the edge of the frame. 
     
     
         4 . The packaging device according to  claim 3 , wherein each supporting face has a width larger than a thickness of the frame. 
     
     
         5 . The packaging device according to  claim 1 , wherein each frame member is unfolded into a flat piece. 
     
     
         6 . The packaging device according to  claim 1 , wherein, after the plugging element of the second frame member is plugged into a positioning opening of the first frame member, an included angle is formed between the first and second frame member. 
     
     
         7 . The packaging device according to  claim 6 , wherein the included angle is a right angle.
