Abstract

One type of tray adaptable to carry articles of different sizes includes a substrate, at least one blocking member, and at least one positioning block. The substrate includes a peripheral region and a middle region within. The blocking member is disposed on the peripheral region of the substrate, and the positioning block is detachably disposed on an inner side of the blocking member facing the middle portion.

What is claimed is: 
     
         1 . A tray comprising a substrate, at least one blocking member, and at least one positioning block, the substrate comprising a peripheral region and a middle region surrounded by the peripheral region, the blocking member is disposed on the peripheral region of the substrate, and the positioning block is detachably disposed on an inner side of the blocking member facing the middle portion. 
     
     
         2 . The tray according to  claim 1 , wherein the blocking member is detachably disposed on the substrate. 
     
     
         3 . The tray according to  claim 2 , wherein the substrate defines at least one first hole, and the blocking member defines at least one second hole corresponding to one or more of the at least one first hole, the blocking member is detachably disposed on the substrate by receiving at least one first tip post in the at least one second hole and the corresponding first holes. 
     
     
         4 . The tray according to  claim 3 , wherein the positioning block defines at least one third hole corresponding to one or more of the first holes, and the positioning block is detachably disposed on the substrate by receiving at least one second tip post in the at least one third hole and the corresponding first holes. 
     
     
         5 . The tray according to  claim 4 , wherein a number of the first holes is equal to or more than a sum of the second holes and the third holes. 
     
     
         6 . The tray according to  claim 1 , wherein the positioning block is magnetically attracted to the substrate by a magnet. 
     
     
         7 . The tray according to  claim 1 , wherein the at least one blocking member is integrally formed with the substrate. 
     
     
         8 . The tray according to  claim 1 , wherein the at least one blocking member comprises three blocking members, the peripheral region comprises a first side portion, a second side portion and a third side portion, the three blocking members are disposed on the first side portion, the second side portion and the third side portion respectively. 
     
     
         9 . The tray according to  claim 8 , wherein the peripheral region further comprises a fourth side portion, the first side portion and the third side portion are connected between the second side portion and the fourth side portion, and the second side portion and the fourth side portion are connected between the first side portion and the third side portion, the at least one positioning block comprises a positioning block disposed on the fourth side portion. 
     
     
         10 . The tray according to  claim 1 , further comprising at least one elastic member disposed on each of the at least one positioning block, the elastic member is configured to provide protections to an article on the substrate from impact forces.
