Packaging Device For Storing Fragile Substrate

Abstract

A packing box for storing a fragile substrate includes a body configured with first and second components. Each of the first and second components includes a base board, and the first and second components are engageable with each other to support the substrate. At least one of the first and second components includes a sidewall extending upward from an edge thereof. A mold with a smaller size can thus be used for making the first and second components, which are combined to form the packing box of a larger size so as to reduce the cost.

1 . A packing box for storing a fragile substrate, characterized in that the packing box includes:
 a body configured by a first component and a second component, each of which includes a base board and a sidewall extending from an edge thereof, wherein the base board of the first component and the base board of the second component are engageable with each other to contiguously form a floor area for supporting the fragile substrate; and   a plurality of buffering pads, each having a dimension smaller than the floor area of the body, and being disposed above the floor area of the body for protecting the fragile substrate;   wherein the first component and the second component are produced by injection molding and configured identically to each other.   
     
     
         2 . The packing box as recited in  claim 1 , characterized in that:
 the first component includes two partial components for respectively forming a left upper quarter and a left lower quarter of the floor area of the body, and the second component includes two partial components for respectively forming a right upper quarter and a right lower quarter of the floor area of the body;   each of the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter is included with a partial base board and a partial sidewall extending from an edge of the corresponding partial base board;   wherein the partial base boards of the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter are interconnected to configure the floor area of the body, and the partial sidewalls of the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter are interconnected to configure a loop.   
     
     
         3 . The packing box as recited in  claim 2 , characterized in that:
 the packing box includes a plurality of connectors, and each connector includes a bracket and a plurality of screws, wherein the bracket is provided with at least four first threaded holes;   wherein each of the base boards of the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter is provided with at least one second threaded hole corresponding to one of the first threaded holes, and each of the screws of the connector penetrates through one of the first threaded holes and anchored in a corresponding one of the second threaded holes so as to securely interconnect the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter together.   
     
     
         4 . The packing box as recited in  claim 2 , characterized in that:
 each of the left upper quarter, the left lower quarter, the right upper quarter and the right lower quarter is formed by injection molding as a single piece;   the left upper quarter is configured identically to the right lower quarter; and   the left lower quarter is configured identically to the right upper quarter.   
     
     
         5 . The packing box as recited in  claim 2 , characterized in that:
 the base board of each of the left upper quarter, the right lower quarter, and the right upper quarter, and the left lower quarter is provided with at least one dowel pin and/or at least one pin hole at adjoining edges thereof, wherein an inner wall of each the pinhole is provided with a latch, while each the dowel pin is provided with a hook engageable with the latch when the dowel pin is inserted into the pinhole so as to securely interconnect the left upper quarter, left lower quarter, right lower quarter and the right upper quarter together.   
     
     
         6 . The packing box as recited in  claim 1 , characterized in that:
 there are at least two buffering pads.   
     
     
         7 . (canceled) 
     
     
         8 . (canceled) 
     
     
         9 . The packing box as recited in  claim 1 , characterized in that
 the base board and the sidewall of the first and second components are made from acrylonitrile butadiene styrene (ABS) or high density polyethylene (HDPE).   
     
     
         10 . (canceled) 
     
     
         11 . (canceled) 
     
     
         12 . The packing box as recited in  claim 3 , characterized in that:
 the bracket has a rectangular shape, and has four first threaded holes respectively arranged at corners thereof.   
     
     
         13 . (canceled) 
     
     
         14 . The packing box as recited in  claim 1 , characterized in that:
 the buffering pads are made from polypropylene.   
     
     
         15 . (canceled) 
     
     
         16 . The packing box recited in  claim 1 , further comprising:
 a cover removably attached to a top of the body to sealingly configure the packing box.   
     
     
         17 . (canceled) 
     
     
         18 . (canceled)
