Abstract

A pack of smoking articles includes: a group of smoking articles; an inner wrapper folded around said group forming a tubular wall wrapping said group, and an upper wall covering a head end of said group; an outer wrapper folded around said group wrapped in said inner wrapper, to form a tubular wall that wraps said group wrapped in said inner wrapper, and a lower wall covering a bottom end of said group; wherein said upper wall is formed by at least two upper flaps which are connected to said tubular wall of said inner wrapper and are folded against said head end to completely cover said head end. The pack includes a tab, arranged protruding from an edge of one of said upper flaps and fixed on a corresponding portion of said inner or outer wrapper to keep said upper flaps against the head end.

1 . A pack of smoking articles, comprising:
 a group of smoking articles;   an inner wrapper which is folded around said group of smoking articles so as to form at least one first tubular wall which wraps said group of smoking articles, and an upper wall which covers a head end of said group of smoking articles;   an outer wrapper which is folded around said group of smoking articles wrapped in said inner wrapper, so as to form at least one second tubular wall which wraps said group of smoking articles wrapped in said inner wrapper, and a lower wall covering a bottom end of said group of smoking articles;   wherein said upper wall is formed by at least two upper flaps which are connected to said first tubular wall of said inner wrapper and are folded against said head end of said group of smoking articles to completely cover said head end of said group of smoking articles,   at least one tab, which is arranged on an edge of one of said at least two upper flaps of said inner wrapper,   wherein said at least one tab is fixed on a corresponding portion of said inner wrapper or of said outer wrapper to keep said at least two upper flaps of said inner wrapper against the head end of said group of smoking articles.   
     
     
         2 . The pack according to  claim 1 , wherein said at least one tab is arranged protruding from an edge of one of said at least two upper flaps of said inner wrapper and has a length such as to exceed an outer contour of said upper wall and fold against said first tubular wall of said inner wrapper. 
     
     
         3 . The pack according to  claim 2 , which has one or more gluing points between said at least one tab and said second tubular wall of said outer wrapper, on a portion of said first tubular wall, configured to identify a corresponding portion of said outer wrapper. 
     
     
         4 . The pack according to  claim 2 , wherein said at least two upper flaps of said inner wrapper are folded against said head end of said group of smoking articles in a condition wherein they at least partially overlap one another, and wherein said at least one tab is arranged on an outermost upper flap among said at least two upper flaps. 
     
     
         5 . A method for packaging a pack of smoking articles, including the steps:
 providing a group of smoking articles;   providing a first sheet of wrapping material and folding said first sheet around said group of smoking articles so as to form at least one first tubular wall that wraps said group of smoking articles, and an upper wall that covers a head end of said group of smoking articles, wherein said upper wall is formed by at least two upper flaps which are connected to said first tubular wall and are folded against said head end of said group of smoking articles to completely cover said head end of said group of smoking articles,   providing a second sheet of wrapping material and folding said second sheet around said group of smoking articles wrapped in said first sheet of wrapping material, so as to form at least one second tubular wall that wraps said group of smoking articles wrapped in said first sheet of wrapping material, and a lower wall that covers a bottom end of said group of smoking articles;   said step of providing said first sheet of wrapping material comprises providing on it at least one tab arranged on an edge of one of said at least two upper flaps of said folded first sheet, and   said method being characterized in that it includes fixing said at least one tab on a corresponding portion of said folded first sheet or of said folded second sheet to maintain said at least two upper flaps of said folded first sheet against said head end of said group of smoking articles.   
     
     
         6 . The method according to  claim 5 , wherein said step of providing said first sheet of wrapping material arranged with said at least one tab comprises providing the first sheet of wrapping material and performing a cutting operation on said first sheet of wrapping material which creates thereon said at least one tab. 
     
     
         7 . The method according to  claim 6 , wherein said step of providing said first sheet of wrapping material arranged with said at least one tab comprises:
 feeding a continuous web of wrapping material,   performing a cutting operation on a longitudinal edge of said continuous web, which creates a plurality of tabs on said longitudinal edge,   transversely cutting said web to divide it into a plurality of wrapping sheets each equipped with at least one respective tab.   
     
     
         8 . The method according to  claim 6 , wherein said step of providing said first sheet of wrapping material arranged with said at least one tab comprises:
 feeding a continuous web of wrapping material,   transversely cutting said web in a cutting operation to divide said web into a plurality of wrapping sheets,   wherein said cutting operation is carried out along a cutting line which separates a single first sheet of wrapping material from said web,   said cutting line being configured to create said at least one tab on said first sheet of wrapping material which is separated from said web, and a complementary notch on said web, or vice versa.   
     
     
         9 . The method according to  claim 5 , wherein said step of folding said first sheet of wrapping material arranged with said at least one tab includes folding said at least one tab against said corresponding portion of said first or second sheet of wrapping material after said first or second sheet of wrapping material has been folded at least partially around said group of smoking articles. 
     
     
         10 . The method according to  claim 5 , wherein providing said first or second sheet of wrapping material comprises providing at least one gluing point on a portion configured, due to the folding of said first or second sheet of wrapping material, to identify said corresponding portion of said folded first or second sheet on which said at least one tab is then fixed. 
     
     
         11 . The method according to  claim 5 , wherein arranging said at least one tab on said first sheet of wrapping material comprises arranging said at least one tab which is configured to be due to the folding of said first sheet—placed on an outermost upper flap among said at least two upper flaps of said folded first sheet; said method further comprising:
 folding said at least one tab against said first tubular wall of said folded first sheet; and 
 fixing said at least one tab to said second tubular wall of said folded second sheet by applying glue.
