Reinforced container construction

Abstract

A container construction includes one or more containers that may be superposed and secured together with couplers. Each container includes a housing having a rear wall and two side walls, and a number of slits formed in each wall. One or more shelves each includes a number of ears engageable into the slits of the housing, for attaching the shelf to the housing. A number of coupling members each includes a channel for receiving the ears of the shelf and each includes one or more catches for engaging with the shelf, and for securing the ears of the shelf to the housing. The ears of the shelf each includes one or more notches for receiving the catches of the reinforcing member.

1 . A container construction comprising: 
 a container including a housing having a rear wall and two side walls, and including a plurality of slits formed in said rear and said side walls thereof,    a shelf including a plurality of ears extended outwardly from an outer peripheral portion and engageable into said slits of said housing respectively, for attaching said shelf to said housing, and    a plurality of coupling members each including a channel formed therein for receiving said ears of said shelf respectively, and each including at least one catch extended therefrom, for engaging with said shelf, and for securing said ears of said shelf to said housing.    
   
   
       2 . The container construction as claimed in  claim 1 , wherein said ears of said shelf each includes at least one notch formed therein, and said at least one catch of said coupling member is engageable into said at least one notch of said ear of said shelf, for anchoring said ears of said shelf to said housing.  
   
   
       3 . The container construction as claimed in  claim 1 , wherein said housing includes a reinforcing member provided in each of said side walls thereof, for reinforcing said side walls of said housing.  
   
   
       4 . The container construction as claimed in  claim 3 , wherein said reinforcing member includes a triangular cross section.  
   
   
       5 . The container construction as claimed in  claim 1 , wherein said housing includes a bottom board attached thereto, for reinforcing a bottom portion of said housing.  
   
   
       6 . The container construction as claimed in  claim 5 , wherein said bottom board includes a peripheral fence extended upwardly therefrom, for engaging with said rear and said side walls of said housing, and for solidly securing said bottom board to said housing.  
   
   
       7 . The container construction as claimed in  claim 5 , wherein said bottom board includes at least one wheel device attached thereto.  
   
   
       8 . The container construction as claimed in  claim 5 , wherein said bottom board includes two sockets formed therein, and said housing includes a reinforcing member provided in each of said side walls and engageable into said sockets of said bottom board.  
   
   
       9 . The container construction as claimed in  claim 8 , wherein said sockets of said bottom board includes a triangular shape, and said reinforcing members of said housing each includes a triangular cross section for engaging into said triangular sockets of said bottom board.  
   
   
       10 . The container construction as claimed in  claim 1 , wherein said shelf includes a reinforcing member provided in a front portion thereof, for reinforcing said shelf.  
   
   
       11 . The container construction as claimed in  claim 10 , wherein said reinforcing member of said shelf includes a triangular cross section.  
   
   
       12 . The container construction as claimed in  claim 10 , wherein said reinforcing member of said shelf includes at least one ear extended therefrom, for engaging into said slits of said housing respectively.  
   
   
       13 . The container construction as claimed in  claim 12 , wherein said at least one ear of said reinforcing member of said shelf includes at least one protrusion extended therefrom, for engaging with said housing.  
   
   
       14 . The container construction as claimed in  claim 1  further comprising a second housing including a rear wall and two side walls, and a plurality of slits formed in said rear and said side walls thereof, and a second shelf including a plurality of ears extended outwardly from an outer peripheral portion thereof, and engageable into said slits of said second housing respectively, for attaching said second shelf to said second housing.  
   
   
       15 . The container construction as claimed in  claim 14  further comprising two corner couplers each including two slots formed therein, and a rib formed between said slots thereof, for receiving said walls of said housing and said second housing respectively.  
   
   
       16 . The container construction as claimed in  claim 14  further comprising two front couplers each including two slots formed therein, for receiving said walls of said housing and said second housing respectively.  
   
   
       17 . The container construction as claimed in  claim 16 , wherein said front couplers each includes a receptacle extended therefrom, and said housing and said second housing each includes a reinforcing member provided in each of said side walls thereof, and engageable into said receptacles of said front couplers respectively.  
   
   
       18 . The container construction as claimed in  claim 17 , wherein said receptacles of said front couplers each includes a triangular cross section, and said reinforcing member of said housing and said second housing each includes a triangular cross section for engaging into said triangular receptacles of said front couplers respectively.
