         7 . An aerosol container for multiple contents discharge according to  claim 1 ,
 wherein a communication/shutoff between the first space and outside, and the communication/shutoff between the second space and outside are operated simultaneously by opening and closing of one valve.   
     
     
         8 . An aerosol container for multiple contents discharge according to  claim 1 ,
 wherein the valve performing the communication/shutoff between the first space and outside, and the valve performing the communication/shutoff between the second space and outside are different.   
     
     
         9 . An aerosol product for multiple contents discharge, comprising:
 the aerosol container for multiple contents discharge according to  claim 1 ,   a first content charged in the first space,   a second content charged in the second space, and   a propellant charged in the first space and/or in the second space.   
     
     
         10 . An aerosol product for multiple contents discharge, comprising:
 the aerosol container for multiple contents discharge according to  claim 2 ,   a first content charged in the first space,   a second content charged in the second space, and   a propellant charged in the third space.   
     
     
         11 . An aerosol product for multiple contents discharge, comprising:
 the aerosol container for multiple contents discharge according to  claim 2 ,   a first content charged in the first space,   a second content and a propellant charged in the second space, and   a gas existing in the third space.   
     
     
         12 . An inner container for inserting into an aerosol container which independently houses a plurality of contents, and which directly separates at least two contents,
 wherein the inner container is formed by overlapping, or folding one or more than two flexible laminated sheets having a metal foil layer and a synthetic resin layer so as to make the synthetic resin layer become an outer surface, and by mutually bonding the peripheral edge of the laminated sheets,   wherein a protecting means is provided in an edge face of the laminated sheet.   
     
     
         13 . An inner container for inserting into an aerosol container which independently houses a plurality of contents, and which directly separates at least two contents,
