Method for manufacturing a package with a simple handle

Abstract

The invention relates to a method for manufacturing a packaging comprising the stages consisting in producing a packaging which is open at its upper end and then in sealing the upper part of the packaging along a leaktight sealing line so as to constitute a top band with the upper end of the packaging, characterized in that the method comprises a supplementary stage consisting in folding said top band down towards the bottom of the packaging and in fixing it onto the packaging so as to form a handle. The invention also proposes a packaging produced by such a method, characterized in that it has a folded-down top band forming a handle.

What is claimed is:  
     
         1 . Method for manufacturing a packaging comprising the stages consisting in producing a packaging which is open at its upper end and then in sealing the upper part of the packaging along a leaktight sealing line ( 21 ) so as to constitute a top band ( 22 ) with the upper end of the packaging, characterized in that the method comprises a supplementary stage consisting in folding said top band ( 22 ) down towards the bottom of the packaging and in fixing it onto the packaging ( 2 ) so as to form a handle (P).  
     
     
         2 . Method according to  claim 1 , characterized in that the top band ( 22 ) is folded down and then fixed onto fixing regions ( 25   a ,  25   b ) of the packaging via corresponding regions of the top band located close to its two lateral edges, in order to form, together with the central part of the top band, a cavity (P) forming a handle.  
     
     
         3 . Method according to the preceding claim, characterized in that said fixing is produced by welding or by adhesive bonding.  
     
     
         4 . Method according to one of claims  2  and  3 , characterized in that said fixing regions are located above said leaktight sealing line ( 21 ).  
     
     
         5 . Method according to one of the preceding claims, characterized in that a finishing sealing line ( 24 ) is also produced at the end of the top band.  
     
     
         6 . Method according to the preceding claim, characterized in that the top band is folded down along a line located between the leaktight sealing line ( 21 ) and the finishing sealing line ( 24 ).  
     
     
         7 . Method according to one of the preceding claims, characterized in that an opening is made in the hollow of the handle (P).  
     
     
         8 . Packaging ( 2 ) produced by a method according to one of the preceding claims, characterized in that it has a folded-down top band ( 22 ) forming a handle.
