Cushioning apparatus

Abstract

A cushioning apparatus includes an air cylinder sheet, a film, and one or more adhesive segment. The air cylinder sheet includes several nodes, and the air cylinder sheet is folded along the nodes to form a first cushioning portion, a second cushioning portion, and a third cushioning portion. The first cushioning portion is closely attached to the bottom of a box for packing an object. Two ends of the film are fixed at the second cushioning portion and the third cushioning portion, respectively. The length of the film is greater than a distance between the second cushioning portion and the third cushioning portion. The adhesive segment is disposed on the film to allow two regions of the film to adhere with each other or to allow the film to adhere to the second cushioning portion or the third cushioning portion.

What is claimed is: 
     
         1 . A cushioning apparatus, adapted to pack an object, the cushioning apparatus comprising:
 an air cylinder sheet comprising a plurality of nodes, wherein the air cylinder sheet is folded along the nodes to form a first cushioning portion, a second cushioning portion, and a third cushioning portion, wherein the second cushioning portion and the third cushioning portion are respectively located at two ends of the first cushioning portion, and the object is on the first cushioning portion;   a film having two ends respectively fixed at the second cushioning portion and the third cushioning portion, wherein the length of the film is greater than the distance between the second cushioning portion and the third cushioning portion; and   at least one adhesive segment disposed on the film, wherein the adhesive segment is adhered to at least two regions of the film or adhered to at least one region of the film and at least one region of the air cylinder sheet, such that the object is in contact with a surface of the film, where the surface of the film faces the first cushioning portion.   
     
     
         2 . The cushioning apparatus according to  claim 1 , wherein the adhesive segment allows the film to adhere to at least one of the second cushioning portion, the third cushioning portion, and a surface of the object. 
     
     
         3 . The cushioning apparatus according to  claim 1 , wherein when the film is not adhered to the adhesive segment, the film is sagged naturally down to the first cushioning portion. 
     
     
         4 . The cushioning apparatus according to  claim 1 , wherein the air cylinder sheet comprises two outer membranes partially connected with each other by a plurality of heat sealing lines, and the air cylinder sheet is inflated between the heat sealing lines to form a plurality of air cylinders, the nodes are located in the air cylinders and connected to inner surfaces of the two outer membranes, an interval is defined between each of the nodes and the corresponding heat sealing line, such that gas is allowed to flow into each of the air cylinders. 
     
     
         5 . The cushioning apparatus according to  claim 1 , wherein the adhesive segment is a double-sided adhesive tape, a pressure sensitive adhesive tape, or the combination of a double-sided adhesive tape and a pressure sensitive adhesive tape. 
     
     
         6 . A cushioning apparatus, adapted to pack an object, the cushioning apparatus comprising:
 an air cylinder sheet comprising a plurality of nodes, wherein the air cylinder sheet is folded along the nodes to form a first cushioning portion, a second cushioning portion, and a third cushioning portion, wherein the second cushioning portion and the third cushioning portion are respectively located at two ends of the first cushioning portion, and the object is on the first cushioning portion;   two films respectively fixed at the second cushioning portion and the third cushioning portion, wherein the total length of the two films is greater than the distance between the second cushioning portion and the third cushioning portion; and   at least one adhesive segment disposed on at least one of the two films so as to adhere the two films with each other and to allow the object to be in contact with a lower surface of each of the two films, where the lower surfaces face the first cushioning portion.   
     
     
         7 . The cushioning apparatus according to  claim 6 , wherein the air cylinder sheet comprises two outer membranes partially connected with each other by a plurality of heat sealing lines, and the air cylinder sheet is inflated between the heat sealing lines to form a plurality of air cylinders, the nodes are located in the air cylinders and connected to inner surfaces of the two outer membranes, an interval is defined between each of the nodes and the corresponding heat sealing line, such that gas is allowed to flow into each of the air cylinders. 
     
     
         8 . The cushioning apparatus according to  claim 6 , wherein the air cylinder sheet further comprises a plurality of air valves and two inner membranes, each of the air valves is located at a first end of the corresponding air cylinder and provided for filling gas, each of the inner membranes is connected to the inner surface of the corresponding outer membrane, a gas inlet is defined between the inner membranes, wherein after gas is delivered into the air cylinders to fill each of the air cylinders, the pressure in each of the air cylinders forces the two inner membranes to adhere with each other. 
     
     
         9 . The cushioning apparatus according to  claim 6 , wherein the adhesive segment allows the two films to adhere to the at least one of the second cushioning portion, the third cushioning portion, and a surface of the object. 
     
     
         10 . The cushioning apparatus according to  claim 6 , wherein when the two films are not adhered to the adhesive film, the two films are sagged naturally down to the first cushioning portion. 
     
     
         11 . The cushioning apparatus according to  claim 6 , wherein the adhesive segment is a double-sided adhesive tape, a pressure sensitive adhesive tape, or the combination of a double-sided adhesive tape and a pressure sensitive adhesive tape.
