Dual pack

Abstract

Disclosed is a dual pack. The dual pack includes a main body having an air pore for passage of air, a storage body configured to receive content therein, the storage body being located within the main body, and a water entrance/exit member configured to penetrate the main body and be connected to the interior of the storage body. The main body and the storage body are flexible, and an inner surface of the main body is separated from an outer surface of the storage body.

1 . A dual pack comprising:
 a main body having an air pore for passage of air;   a storage body configured to receive content therein, the storage body being located within the main body;   a water entrance/exit member including a water entrance/exit body that penetrates the main body and the storage body and has a flow path, through which the content is discharged outward, and a lid to control discharge of the content;   a drainage line mounted to the water entrance/exit body, the drainage line being adapted to open the flow path by separating the lid from the flow path, so as to enable discharge of the content; and   at least one interlayer member located between the main body and the storage body,   wherein the storage body is flexible such that a volume of the storage body is reduced when the content is discharged from the storage body, and outside air equal in amount to a reduced volume of the storage body is introduced into the main body, the air introduced into the main body serving to prevent deformation of the main body.   
     
     
         2 . The dual pack according to  claim 1 , wherein the interlayer member is an insulator to prevent transfer of heat from the interior of the storage body to the outside, or from the outside of the storage body into the storage body. 
     
     
         3 . The dual pack according to  claim 1 , wherein the interlayer member is a cooling and heating device to cool or heat the content stored in the storage body. 
     
     
         4 . The dual pack according to  claim 1 , wherein the interlayer member is a protective layer to prevent the storage body from being damaged by external shock. 
     
     
         5 . The dual pack according to  claim 1 , wherein the interlayer member is a light emitting member. 
     
     
         6 . The dual pack according to  claim 1 , wherein the interlayer member is a display panel. 
     
     
         7 . The dual pack according to  claim 1 , further comprising a shield film located within the main body, a portion of the shield film being affixed to an inner surface of the main body such that the remaining portion of the shield film is attached to or separated from the periphery of the air pore. 
     
     
         8 . The dual pack according to  claim 1 , further comprising a printed section provided on an outer surface of the main body.
