Cushion material for packaging product therein and suspension air-packing method using same

Abstract

A cushion material for packaging a product is capable of absorbing shocks and impacts and being used for various types of product in a multipurpose manner. A large volume of the cushion materials can be produced through an automatic production process at a low cost. A suspension air-packing method using the cushion material packs the product in a mid-hanging manner. The cushion material includes at least two flexible films facing one another and the edges of the two films are heat-sealed, a bag portion for holding the product therein, and a cushion portion established on the outer periphery of the bag portion which will be inflated by the air when the compressed air.

1 . A cushion material for holding an object to be packaged in a mid-air suspension manner, comprising: 
 two thermoplastic films overlapped with one another where edges thereof are heat-sealed;    a bag portion formed at an inner area of said two thermoplastic films for holding the object to be packaged therein;    a cushion portion that is established around said bag portion at an outer area of the two thermoplastic films, said cushion portion will be filled with compressed air; and    a sealed portion established at a boundary area between the bag portion and the cushion portion where a slit is formed the sealed portion to increase flexibility of the bag portion.    
   
   
       2 . A cushion material as defined in  claim 1 , further comprising an opening for inserting the object to be packed there through at least one side of said bag portion.  
   
   
       3 . A cushion material as defined in  claim 2 , wherein said bag portion is provided with a cut off on one of the thermoplastic films near the opening for inserting the object to be packaged.  
   
   
       4 . A cushion material as defined in  claim 1 , further comprising an air opening for injecting the air therethrough.  
   
   
       5 . A cushion material as defined in  claim 4 , wherein said air opening for injecting the air therethrough prevents the injected air from reverse flowing by a labyrinth construction or a narrow pathway.  
   
   
       6 . A cushion material as defined in  claim 4 , wherein said air opening for injecting the air therethrough prevents the injected air from reverse flowing by having a check valve.  
   
   
       7 . A cushion material as defined in  claim 4 , wherein said air opening for injecting the air therethrough extends through a main body of the cushion material.  
   
   
       8 . A cushion material as defined in  claim 1 , wherein a sealing portion is formed on each corner of the cushion portion through a heat-sealing treatment.  
   
   
       9 . A suspension air-packing method for holding an object to be packaged in a mid-air suspension manner, comprising the steps of: 
 providing a cushion material formed of two thermoplastic films overlapped with one another where the cushion material includes a bag portion formed at an inner area of the two thermoplastic films, a cushion portion formed at an outer area of the two thermoplastic films, and a sealed portion established at a boundary area between the bag portion and the cushion portion;    inserting an object to be packed through an opening of the bag portion;    inflating the cushion portion by supplying compressed air; and    installing the cushion material having the object therein in a container box.    
   
   
       10 . A suspension air-packing method as defined in  claim 9 , said step of installing the cushion material includes a step of fitting the cushion portion with a space created by support members within the container box.  
   
   
       11 . A suspension air-packing method as defined in  claim 9 , said step of installing the cushion material includes a step of installing two or more cushion materials each packing an object in the bag portion in an overlapping manner in the container box.  
   
   
       12 . A suspension air-packing method as defined in  claim 9 , said step of installing the cushion material includes a step of installing two or more cushion materials where an object to be packed is inserted between two adjacent cushion materials in the container box.  
   
   
       13 . A suspension air-packing method as defined in  claim 9 , wherein said cushion material includes a sealed portion established at a boundary area between the bag portion and the cushion portion where a slit is formed the sealed portion to increase flexibility of the bag portions.  
   
   
       14 . A suspension air-packing method as defined in  claim 9 , wherein said cushion material includes an air opening for injecting the air therethrough, wherein the opening prevents the injected air from reverse flowing by having a labyrinth construction or a narrow pathway.  
   
   
       15 . A suspension air-packing method as defined in  claim 9 , wherein said cushion material includes an air opening for injecting the air therethrough, wherein the opening prevents the injected air from reverse flowing by having a check valve made of thermoplastic film.  
   
   
       16 . A suspension air-packing method as defined in  claim 10 , wherein said support members contact inner walls of the container box where the cushion portion of the cushion material is inserted in the space of each support member.
