Packing apparatus having integrated internal buffer

Abstract

An exemplary packing box ( 2 ) includes a receptacle portion ( 21 ) and at least one buffer portion ( 23 ). The receptacle portion includes a plurality of side walls ( 213, 215, 217 ) and a base ( 211 ) perpendicular to thereof. The side walls and the base cooperatively define a receiving space. The at least one buffer portion extends from at least one of the side walls. The at least one buffer portion is located in the receiving space and including a first supporting member (213 b ) and at least one buffer layer ( 233 ).

1 . A packing box, comprising: 
 a receptacle portion comprising a plurality of side walls and a base, the side walls being perpendicular to the base, the base and the side walls cooperatively defining a receiving space; and    at least one buffer portion extending from at least one of the side walls, the at least one buffer portion located in the receiving space and comprising a first supporting member and at least one buffer layer.    
   
   
       2 . The packing box as claimed in  claim 1 , wherein the receptacle portion further comprises a cover opposite to the base.  
   
   
       3 . The packing box as claimed in  claim 1 , wherein the at least one buffer portion is four buffer portions.  
   
   
       4 . The packing box as claimed in  claim 3 , wherein the buffer portions are arranged at four corners of the base respectively.  
   
   
       5 . The packing box as claimed in  claim 1 , wherein a height of the first supporting member is less than a height of each of the side walls.  
   
   
       6 . The packing box as claimed in  claim 1 , wherein the supporting member is perpendicular to the base.  
   
   
       7 . The packing box as claimed in  claim 1 , wherein the at least one buffer layer is parallel to the base.  
   
   
       8 . The packing box as claimed in  claim 5 , further comprising a second supporting member, wherein a height of the second supporting member is substantially the same as the height of each of the side walls.  
   
   
       9 . The packing box as claimed in  claim 1 , wherein the receptacle portion comprises corrugated paper.  
   
   
       10 . A packing box, comprising: 
 a receptacle portion comprising a plurality of side walls and a base, the side walls being perpendicular to the base, at least one of the side walls comprising a first extending portion extending into a space defined by the receptacle portion, wherein the first extending portion comprises a buffer portion, and the buffer portion comprises a first supporting member and a buffer layer.    
   
   
       11 . The packing box as claimed in  claim 10 , wherein the receptacle portion further comprises a cover opposite to the base.  
   
   
       12 . The packing box as claimed in  claim 10 , wherein the at least one of the side walls is two of the side walls, which each comprise the first extending portion and a second extending portion, the second extending portion comprises a buffer portion, and the buffer portion of the second extending portion comprises a first supporting member and a buffer layer.  
   
   
       13 . The packing box as claimed in  claim 12 , wherein the buffer portions of the first and second extending portions are arranged at four corners of the base respectively.  
   
   
       14 . The packing box as claimed in  claim 10 , wherein a height of the first supporting member is less than a height of each of the side walls.  
   
   
       15 . The packing box as claimed in  claim 10 , wherein the first supporting member is perpendicular to the base.  
   
   
       16 . The packing box as claimed in  claim 10 , wherein the buffer layer is parallel to the base.  
   
   
       17 . The packing box as claimed in  claim 14 , wherein the buffer portion further comprises a second supporting member, and a height of the second supporting member is greater than the height of the first supporting member.  
   
   
       18 . The packing box as claimed in  claim 10 , wherein the receptacle portion comprises corrugated paper.  
   
   
       19 . A packing box formed by folding a sheet, comprising: 
 first, second third and fourth small side faces wherein the first and the third side faces are opposite to each other while adjacent to the second and the fourth side faces, and the second and the fourth side faces are opposite to each other while adjacent to the first and the third side faces; 
 two opposite large main faces circumferentially interconnected to each other by said first, second, third and fourth small side faces so as to form a rectangular box configuration with a cavity therein, each of said small side faces defining a long longitudinal direction and a short transverse direction;  
 the first small side face being directly extending between both said two large main faces,  
 in an extended manner, at least one buffer portion directly extending from one longitudinal end in said longitudinal direction toward the second side face, and adapted to be folded back into the cavity and located around a corner between said first side face and said second side face.  
   
   
   
       20 . The packaging box as claimed in  claim 19 , wherein in said extended manner, the second side face directly extends from one of said two main faces, and the at least one buffer extends beyond said second side face and cooperate with said one of the two main faces to sandwich said second side face therebetween.
