Packaging case

Abstract

A packaging case adapted for packing an article therein includes a fastening shell and a plurality of buffering elements. Each wall of the fastening shell defines at least one insertion hole. The buffering elements are dismountably inserted into the insertion holes of the fastening shell with tops thereof projecting out of the insertion holes. The fastening shell and the buffering elements are designed separately, so the buffering elements fully afford an external force struck on the buffering elements for effectively preventing cracks being caused between each buffering element and the fastening shell. Accordingly, the fastening shell is designed with a thinner thickness to lower a material cost and a transportation cost. Furthermore, the buffering elements assembled to the fastening shell are changeable to make the buffering elements dismountably inserted into the insertion holes properly and simply. So a better buffering function of the packaging case is realized.

What is claimed is: 
     
         1 . A packaging case adapted for packing an article therein, comprising:
 a fastening shell, each wall of the fastening shell defining at least one insertion hole; and   a plurality of changeable buffering elements dismountably inserted into the insertion holes of the fastening shell with tops thereof projecting out of the insertion holes.   
     
     
         2 . The packaging case as claimed in  claim 1 , wherein each buffering element has an insertion portion inserted in the insertion hole, and a buffering head of a substantial frustum shape forming on a top of the insertion portion and projecting out of the insertion hole. 
     
     
         3 . The packaging case as claimed in  claim 1 , wherein the fastening shell is made of a hollow sandwich material.
