Container and foolproof device thereof

Abstract

A container comprises a first cover and a second cover, in which the first cover comprises an internal space. The container further comprises a plate disposed on the second cover. The second cover is provided with at least one first foolproof device, while the plate is provided with at least one second foolproof device. When the second foolproof device is engaged with the first foolproof device, the plate and the second cover are generally fixedly positioned with respect to each other.

1 . A container for storing or transporting an article, comprising:
 a first cover, forming an internal space;   a second cover, for separating the internal space from outside, wherein the second cover comprises at least one first foolproof device; and   a plate, disposed on a surface of the second cover facing the internal space, and comprising at least one second foolproof device;   wherein the plate and the second cover are generally fixedly positioned with respect to each other when the second foolproof device is engaged with the first foolproof device in a particular orientation.   
     
     
         2 . The container according to  claim 1 , wherein the plate and the metal line are not fixedly positioned with respect to each other when the second foolproof device is not engaged with the first foolproof device. 
     
     
         3 . The container according to  claim 1 , wherein the first foolproof device is at least one recess and the second foolproof device is at least one protrusion corresponding to the recess. 
     
     
         4 . The container according to  claim 1 , wherein the first foolproof device is at least one protrusion and the second foolproof device is at least one recess corresponding to the protrusion. 
     
     
         5 . The container according to  claim 1 , wherein the second cover further comprises a frame and a door. 
     
     
         6 . The container according to  claim 1 , wherein the container is a reticle pod or a single-reticle SMIF-pod. 
     
     
         7 . The container according to  claim 1 , further comprising a metal liner. 
     
     
         8 . The container according to  claim 1 , wherein the plate is made of an electrically conductive material. 
     
     
         9 . The container as claimed in  claim 8 , further comprising a metal liner, wherein the metal liner is made of an electrically conductive material and in electrical communication with the plate. 
     
     
         10 . A container for storing or transporting an article, comprising:
 a first cover, forming an internal space;   a second cover, for separating the internal space from outside;   a plate, disposed on a surface of the second cover facing the internal space, and comprising at least one third foolproof device on a surface thereof facing the internal space; and   a metal liner, disposed on the plate and comprising a fourth foolproof device;   wherein the plate and the metal liner are generally fixedly positioned, and therefore will not move, with respect to each other when the third foolproof device is engaged with the fourth foolproof device in a particular orientation, so that the plate and the metal liner form a space to accommodate the article.   
     
     
         11 . The container according to  claim 10 , wherein the plate and the metal liner are not fixedly positioned with respect to each other when the third foolproof device is not engaged with the fourth foolproof device. 
     
     
         12 . The container according to  claim 10 , wherein the third foolproof device is at least one sidewall. 
     
     
         13 . The container according to  claim 12 , wherein the sidewall protrudes from the surface of the plate facing the internal space. 
     
     
         14 . The container according to  claim 12 , wherein the sidewall is sunk into the surface of the plate facing the internal space. 
     
     
         15 . The container according to  claim 12 , wherein the fourth foolproof device presses against the sidewall. 
     
     
         16 . A container for storing or transporting an article, comprising:
 a first cover, forming an internal space;   a second cover, for separating the internal space from outside, wherein the second cover comprising at least one fifth foolproof device on a portion thereof facing the internal space; and   a metal liner, disposed on the second cover and comprising at least one sixth foolproof device;   wherein the metal liner and the second cover form a space to accommodate the article when the sixth foolproof device is engaged with the fifth foolproof device in a particular orientation.   
     
     
         17 . The container according to  claim 16 , wherein the second cover and the metal liner do not form the space to accommodate the article when the fifth foolproof device is not engaged with the sixth foolproof device. 
     
     
         18 . The container according to  claim 16 , wherein the second cover is provided therein with a locking device for locking the first cover and the second cover. 
     
     
         19 . The container according to  claim 18 , wherein the fifth foolproof device is part of the locking device. 
     
     
         20 . The container according to  claim 16 , wherein the sixth foolproof device is a curved portion of the metal liner.
