Packaging case

Abstract

The present invention relates to a packaging case comprising: an inner case having at least three sidewalls for packaging products; and an outer case having support pieces supporting the pair of inner case sidewalls, which face each other, so as to prevent the movement of the inner case, encompassing the remaining region, which excludes the inner case sidewalls supported by the support pieces, and accommodating and packaging the inner case, wherein the support pieces are foldably provided to the outer case.

1 . A packaging case comprising:
 an inner case having at least three sidewalls for packaging a product; and   an outer case having support pieces supporting a pair of inner case sidewalls, which face each other, so as to prevent a movement of the inner case, surrounding a remaining region excluding the inner case sidewalls supported by the support pieces, and accommodating and packaging the inner case,   wherein the support pieces are foldably provided to the outer case.   
     
     
         2 . The packaging case of  claim 1 , wherein each of the support pieces supports at least a periphery of an associated sidewall. 
     
     
         3 . The packaging case of  claim 1 , wherein the inner case has a shape of a square pillar that is open at both sides thereof. 
     
     
         4 . The packaging case of  claim 3 , wherein any one of the four sidewalls of the inner case comprises a first overlapping portion and a second overlapping portion that are cut to partially overlap each other,
 the first overlapping portion and the second overlapping portion are attached to each other by an adhesive or tape, or a cut-out portion that is partially cut is foldably formed on a surface of the first overlapping portion and a free end of the second overlapping portion is fitted into the cut-out portion.   
     
     
         5 . The packaging case of  claim 1 , wherein the pair of sidewalls of the inner case supported by the support pieces comes into close contact with the packaged product to support the product.
