Shipping container

Abstract

The present invention disclosed a shipping container comprising a pair of side walls, a rear end, a front end, a roof, a floor and a base frame; said base frame further comprising two longitudinal bottom side rails and numbers of parallel bottom cross members, wherein said floor is made up of corrugated steel floor. On the premise of passing ISO test, it provides a container which is lighter in tare weight, less in material consumed and lower in production cost.

1 . A shipping container, comprising a pair of side walls, a rear end, a front end, a roof, a floor and a base frame; said base frame further comprising two longitudinal bottom side rails and numbers of parallel bottom cross members, wherein said floor is made up of corrugated steel floor.  
   
   
       2 . A shipping container according to  claim 1 , wherein said floor is made up of corrugated steel floor which is directly paved on said bottom cross members, and welded to the external side of the bottom cross members, constituting an integral rigid structure.  
   
   
       3 . A shipping container according to  claim 2 , wherein said bottom cross members may be made of steel bars of C-shape cross sectional form.  
   
   
       4 . A shipping container according to  claim 2 , wherein the cross sectional form of the bottom cross members is L-shaped, at the edge of the bottom cross member, there installed many convex teeth matching with the concave grooves of the corrugated floor, helping the bottom cross members to be welded to the corrugated steel floor.  
   
   
       5 . A shipping container according to  claim 2 , wherein there are non metallic stuffing filled within all the grooves of the corrugated steel floor.  
   
   
       6 . A shipping container according to  claim 5 , wherein said non metallic stuffing may be made of wood, or foam, or plastics.  
   
   
       7 . A shipping container according to  claim 2 , wherein thin plate is paved on the corrugated steel floor.  
   
   
       8 . A shipping container according to  claim 7 , wherein said thin plate may be made of thin wooden plate, composite plate or steel plate.  
   
   
       9 . A shipping container according to  claim 2 , wherein said non metallic stuffing is filled within some of the grooves of the corrugated steel floor.  
   
   
       10 . A shipping container according to  claim 9 , wherein the grooves with non metallic stuffing filled in are in a certain proportion to the grooves without non metallic stuffing filled in.  
   
   
       11 . A shipping container according to  claim 9 , wherein said non metallic stuffing may be made of wood, or foam, or plastics.  
   
   
       12 . A shipping container according to  claim 5 , wherein the non metallic stuffing filled in the grooves of the corrugated steel floor is continuously distributed along the grooves.  
   
   
       13 . A shipping container according to  claim 9 , wherein the non metallic stuffing filled in the grooves of the corrugated steel floor is continuously distributed along the grooves.  
   
   
       14  A shipping container according to  claim 5 , wherein the non metallic stuffing filled in the grooves of the corrugated steel floor is incontinuously distributed along the grooves.  
   
   
       15  A shipping container according to  claim 9 , wherein the non metallic stuffing filled in the grooves of the corrugated steel floor is incontinuously distributed along the grooves.  
   
   
       16 . A shipping container according to  claim 5 , wherein said corrugated steel floor may be continuous, the non metallic stuffing completely filled in the grooves of the corrugated steel floor.  
   
   
       17 . A shipping container according to  claim 9 , wherein said corrugated steel floor may be continuous, the non metallic stuffing completely filled in the grooves of the corrugated steel floor.  
   
   
       18 . A shipping container according to  claim 5 , wherein said corrugated steel floor is disconnected at the position where the non metallic stuffing is filled, said non metallic stuffing is held within a concavity which is formed by two adjacent disconnected corrugated floors and has an opening at its bottom.  
   
   
       19 . A shipping container according to  claim 9 , wherein said corrugated steel floor is disconnected at the position where the non metallic stuffing is filled, said non metallic stuffing is held within a concavity which is formed by two adjacent disconnected corrugated floors and has an opening at its bottom.  
   
   
       20 . A shipping container according to  claim 2 , wherein the wavelength of each corrugation of the steel floor is not equal to each other, and said non metallic stuffing is filled in the wider grooves.  
   
   
       21 . A shipping container according to  claim 2 , wherein the wavelength of each corrugation of the corrugated steel floor is equal to each other.
