Corrugated cabinet

Abstract

A corrugated cabinet of the present invention is provided with a main body and a back plate. The main body consists of several vertical plates and several transversal plates, which define at least two compartments therebetween. Each compartment has a rear opening, which is sealed by the back plate. The back plate includes several cardboards that are entirely enveloped by a paper skin. Furthermore, a seam is interposed between each two adjacent cardboards, and the seam has a width substantially equal to a sum of thicknesses of the two cardboards. Whereby, the back plate is foldable along the scam and becomes less space-consuming before sealing the rear openings.

1 . A corrugated cabinet, comprising:
 a main body, consisting of several vertical plates and several transversal plates, the vertical and transversal plates being made of corrugated board, two glue layers being disposed between each of the vertical plate and the adjacent transversal plate, and an isolator being sandwiched between the glue layers, such that the vertical and transversal plates being bound together and defining at least two compartments, each of which has a front opening and a rear opening; and   a back plate, sealing the rear openings of the compartments, the back plate is foldable.   
   
   
       2 . The corrugated cabinet of  claim 1 , wherein the back plate has at least one folding line, along which the back plate is foldable, the folding line divides the back plate into several parts, each of which corresponds to one of the rear openings. 
   
   
       3 . The corrugated cabinet of  claim 1 , wherein the back plate comprises several cardboards, each of which has a configuration corresponding to one of the rear openings, the cardboards are arranged to form a matrix corresponding to a permutation of the compartments, and a paper skin entirely envelops the matrix of the cardboards;
 wherein a seam is interposed between each two adjacent cardboards, the seam has a width substantially equal to a sum of thicknesses of the two cardboards, whereby the back plate is foldable along the seam and becomes less space-consuming before sealing the rear openings.   
   
   
       4 . The corrugated cabinet of  claim 3 , wherein the seam overlaps the vertical plate or the transversal plate, which locates between two adjacent compartments. 
   
   
       5 . The corrugated cabinet of  claim 3 , wherein the skin comprises a thinner outer skin and a thicker inner skin, a width and a length of the outer skin are bigger than a width and a length of the matrix of the cardboards respectively, and a width and a length of the inner skin are smaller than the width and the length of the matrix of the cardboards respectively, the outer skin covers a whole surface of the matrix facing away the rear openings, and rims of the outer skin, which extend beyond a configuration of the matrix, are folded inward to cover a part of a surface of the matrix facing the rear openings, the inner skin covers the surface of the matrix facing the rear openings, and rims of the inner skin overlap a part of the rims of the outer skin. 
   
   
       6 . The corrugated cabinet of  claim 1 , further comprising several door plates to selectively close the front openings of the compartments respectively. 
   
   
       7 . The corrugated cabinet of  claim 1 , further comprising several partitions, each of which being disposed in one of the compartments, a height of each of the partitions being substantially equal to that of its corresponding compartment, such that the partitions can stand, either movably or firmly, in the compartments respectively.
