Rectangular parallelepiped paper made entrainer

Abstract

The paper made entrainer is formed into a rectangular parallelepiped figure basically comprises a longitudinal framework, a transverse framework, a cylindrical supporting column, and a loading board. It has several advantages namely: easy to assemble and detach with low cost because the component parts are mutually engaged one another by insertion, by adjusting number of frameworks and supporting columns, the entrainer is able to carry many loads of different weight. The structure is made of paper so that the decayed entrainer is possible for recyling.

1 . A rectangular parallelepiped paper made entrainer basically comprising: 
 a transverse framework with several engagement slits formed on its wall    a longitudinal framework with several engagement slits formed on its wall for engaging with said transverse framework vertically;    a supporting column provided with several engagement slits on its wall surface to be engaged with said two frameworks after they have engaged with each other; and    a loading board.    
   
   
       2 . The paper made entriner of  claim 1 , wherein said supporting column is configurated into cylindrical shape and said engagement slits are formed on its wall surface.  
   
   
       3 . The paper made entrainer of  claim 1 , wherein number of said slits formed on said longitudinal framework, said transverse framework, and said supporting columns can be appropriately increased or decreased according to actual need.  
   
   
       4 . The paper made entriner of  claim 1 , wherein number of said longitudinal and said transverse frameworks and said supporting column can be increased appropriately to intensify the supporting strength.  
   
   
       5 . The paper made entrainer of  claim 1 , wherein the surface of said longitudinal and said transverse frameworks are reinforced by corrugation or adding ribs.
