Flexible packaging of the bag type with reclosing device

Abstract

Flexible package ( 1 ) of the bag type for loosely packaged perishable food products, comprising: a front wall ( 2 ) and a rear wall ( 3 ) situated opposite each other, defining on the upper part a closing fin ( 4 ) and laterally connected together by two gusset walls ( 5 ); and a reclosing insert ( 10 ) comprising an attachment portion ( 7 ), externally adhering to said rear wall ( 3 ), and a non-adhesive free portion ( 8 ), contiguous to said attachment portion ( 7 ) and defining between itself and the rear wall ( 3 ) an insertion space ( 6 ) open at the top; said free portion ( 8 ) being able to retain, in a reclosing configuration, a folded-over portion of said closing fin ( 4 ) within said insertion space ( 6 ).

1 . A flexible package of the bag type for loosely packaged perishable food products, comprising: a front wall and a rear wall situated opposite each other, defining on the upper part a closing fin and laterally connected together by two gusset walls; and a reclosing insert comprising an attachment portion, externally adhering to said rear wall, and a non-adhesive free portion, contiguous to said attachment portion and defining between itself and the rear wall an insertion space open at the top; said free portion being adapted to retain, in a reclosing configuration, a folded-over portion of said closing fin within said insertion space. 
     
     
         2 . The package according to  claim 1 , wherein said reclosing insert is a rigid planar element. 
     
     
         3 . The package according to  claim 2 , wherein said reclosing insert is a cardboard sheet. 
     
     
         4 . The package according to  claim 2 , wherein said reclosing insert is made of plastic material. 
     
     
         5 . The package according to  claim 2 , wherein said attachment portion is glued onto the outer surface of the rear wall, said free portion being instead without adhesive. 
     
     
         6 . The package according to  claim 5 , wherein said attachment portion has an extension which is at least equal to one fourth of the overall extension of the reclosing insert. 
     
     
         7 . The package according to  claim 3 , wherein said reclosing insert has a substantially rectangular profile, which is horizontally subdivided into an attachment portion and a free portion. 
     
     
         8 . The package according to  claim 7 , wherein the attachment portion has a lower skirt which is smaller in size than the rest of the substantially rectangular profile, so as to improve the adhesion to the outer surface of the rear wall. 
     
     
         9 . The package according to  claim 1 , wherein the upper edge of the reclosing insert, in a shelf configuration, is downwardly displaced with respect to the upper edge of the closing fin. 
     
     
         10 . The package according to  claim 1 , wherein the walls are made of paper material. 
     
     
         11 . The package according to  claim 1 , wherein the walls are made of plastic material. 
     
     
         12 . A method for reclosing a flexible package according to  claim 1 , comprising, following opening of the closing fin so as to define an upper mouth for access to the products, the steps of:
 folding-over at least twice said closing fin against the rear wall along a first folding axis and a second folding axis which is parallel to and below the first axis;   inserting the resulting closing fin, which is folded-over at least twice, into the insertion space under the free portion.
