Abstract

A cigarette package has an inner pack 12 obtained by wrapping a cigarette bundle in aluminum-evaporated paper (inner wrapper), a tongue-lid inner box 10 that sealedly contains the inner pack 12 , and a hinged-lid outer box 2 that contains the inner box 10 , the package in which the inner box 10 is formed by folding an inner blank around the inner pack 12 , and the inner blank has a layer structure in which a polypropylene resin layer is formed on each side of an aluminum layer.

1 . A cigarette package comprising: 
 an inner pack obtained by wrapping a cigarette bundle in an inner wrapper;    an inner box sealedly containing said inner pack, and including a box body with an open end and a lid for opening/closing the open end of the box body, wherein the box body and the lid are formed of an inner blank, said inner blank being heat-sealable and having a shielding layer therein with respect to aroma and flavor components released from the cigarette bundle; and    a hinged-lid outer box formed of a paper outer blank and containing said inner box.    
   
   
       2 . The cigarette package according to  claim 1 , wherein:
