Shock-absorbing packaging device

Abstract

A packaging device has a container provided with a shock-absorbing unit that includes a bottom pad, and a plurality of side pads extending upward from opposite sides of the bottom pad. Each of the bottom and side pads includes a plate member that has a corrugated base plate region and a peripheral flange surrounding the corrugated base plate region. The corrugated base plate region projects from an inner surface of the container to absorb shock when the peripheral flange abuts against the inner surface. Partition pads are provided to span opposite side pads when an object to be packaged is small.

         3 . The packaging device of  claim 2 , wherein said partition pad has a plastic plate member that has a corrugated partition plate region, and a marginal flange surrounding and projecting from said corrugated partition plate region. 
     
     
         4 . The packaging device of  claim 3 , wherein said corrugated partition plate region has a plurality of ribs that extend in a direction transverse to directions along which said ribs of said plate members of said side pads extend and that define grooves therebetween. 
     
     
         5 . The packaging device of  claim 3 , wherein said partition unit includes a plurality of said partition pads, said side pads having front, rear, left and right side pads, said partition pads including a first partition pad spanning said front and rear side pads, and a second partition pad spanning said left and right side pads, said first and second partition pads extending one above the other. 
     
     
         6 . The packaging device of  claim 5 , wherein each of said first and second partition pads is vertical and has a height smaller than that of said front, rear, left and right side pads. 
     
     
         7 . The packaging device of  claim 6 , wherein said height of each of said first and second partition pads is half of a height of said plate members of said front, rear, left and right side pads. 
     
     
         8 . The packaging device of  claim 2 , wherein said shock-absorbing unit further includes a top pad, each of said top and bottom pads including a plate member which has a peripheral flange surrounding a corrugated base plate region that is formed with a plurality of substantially parallel grooves and ribs, said corrugated base plate region of said top or bottom pad projecting inwardly from said inner surface of said container when said peripheral flange of said top or bottom pad abuts against said inner surface. 
     
     
         9 . A foldable pad for protecting an object placed inside a container, said foldable pad comprising:
 four plate members that are connected foldably to each other;   one of said plate members having front, rear, left and right sides;   three of said plate members being connected respectively to said front and rear sides and said left or right side and being foldable upward from said one of said plate members;   each of said plate members having a corrugated base plate region and a peripheral flange surrounding said corrugated base plate region, said peripheral flange being adapted to abut against an inner surface of the container, said corrugated base plate region being adapted to project from the inner surface of the container and to cushion the object; and   said corrugated base plate region being deformable to absorb shock and having a plurality of ribs that define grooves therebetween.   
     
     
         10 . The foldable pad of  claim 9 , wherein said ribs of said three of said plate members are substantially vertical when folded upward, said peripheral flange extending obliquely and flaring outwardly from said corrugated base plate region. 
     
     
         11 . A packaging device, comprising:
 a container; and   a shock-absorbing unit disposed within said container and abutting against an inner surface of said container, said shock-absorbing unit including:
 a bottom pad having opposite sides; 
 a plurality of side pads extending upward from said opposite sides of said bottom pad; 
 each of said bottom and side pads including a plate member which has a corrugated base plate region and a peripheral flange surrounding said corrugated base plate region, said corrugated base plate region projecting from an inner surface of said container when said peripheral flange abuts against said inner surface, said corrugated base plate region being deformable to absorb shock. 
   
     
     
         12 . The packaging device of  claim 11 , wherein said side pads includes front, rear, left and right side pads, said bottom pad including a pair of said plate members, each of said front and rear side pads including a pair of said plate members, each of said left and right side pads including one said plate member, one of said plate members of said bottom pad being formed foldably as one piece with one of said plate members of each of said front and rear side pads and said plate member of one of said left and right side pads, each of said corrugated base plate region having a plurality of ribs that define grooves therebetween. 
     
     
         13 . The packaging device of  claim 12 , wherein said plate members of each of said bottom pad, said front side pad, and said rear side pad are spaced apart from each other inside said container by a distance. 
     
     
         14 . The packaging device of  claim 12 , wherein said container has a plurality of corners, said peripheral flanges of said plate members of said side pads having protrusion-and-recess engagement surfaces that are interengaged at said corners. 
     
     
         15 . The packaging device of  claim 12 , wherein said container has a plurality of corners, said peripheral flange of said plate member of each of said left and right side pads abutting against said peripheral flanges of said plate members of said front and rear side pads at said corners. 
     
     
         16 . The packaging device of  claim 15 , wherein each of said peripheral flanges of said side pads flares outwardly from a corresponding one of said corrugated base plate regions. 
     
     
         17 . The packaging device of  claim 11 , further comprising a top pad disposed on top of said side pads, said top pad including a plate member that has a peripheral flange surrounding a corrugated base plate region and abutting against said inner surface of said container, said corrugated base plate region of said top pad projecting from said inner surface and being deformable to absorb shock.
