Bag including closing profiles actuated by a slider

Abstract

The present invention relates to a bag ( 1 ) including: two generally parallel sheets ( 12, 13 ); matching closing profiles ( 2, 3 ) fixed on these sheets ( 12, 13 ); a slider ( 5 ) for actuating the profiles ( 2, 3 ), this slider ( 5 ) comprising flanks ( 51, 52 ) each inner surface of which bears a boss ( 53, 54 ). This bag is remarkable by the fact that said sheets ( 12, 13 ) include on their outer faces, and outside said slider ( 5 ), abutment means ( 6 ) capable of immobilizing said sheets ( 12, 13 ) relatively to said slider ( 5 ) along a direction generally perpendicular to the displacement axis (X-X′) of the slider ( 5 ).

1 . A bag ( 1 ) comprising:
 two generally parallel sheets ( 12 ,  13 ) forming main walls of the bag;   matching closing profiles ( 2 ,  3 ) respectively fixed on said sheets ( 12 ,  13 );   a slider ( 5 ) for actuating the profiles ( 2 ,  3 ) upon closing and opening, said slider ( 5 ) comprising opposing flanks ( 51 ,  52 ), each inner surface of which bears a boss ( 53 ,  54 ) directed towards the opposite flanks, so that the sheets ( 12 ,  13 ) forming the main walls converge towards each other, said profiles ( 2 ,  3 ) towards said bosses ( 53 ,  54 );   wherein said sheets ( 12 ,  13 ) comprise on their outer faces and outside said slider ( 5 ), abutment means ( 6 ) capable of immobilizing said sheets ( 12 ,  13 ) relative to said slider ( 5 ) along a direction generally perpendicular to a displacement axis (X-X′) of the slider ( 5 ).   
   
   
       2 . The bag according to  claim 1 , further comprising, parallel to said profiles ( 2 ,  3 ), between said sheets ( 12 ,  13 ) and at the mouth ( 10 ) of the bag, additional raised relief means ( 4 ) positioned on the inside of the closing profiles ( 2 ,  3 ), designed to provide a seal by forming a barrier between the sheets ( 12 ,  13 ) in the closure position of the bag, said additional relief means ( 4 ) being adapted so as to be urged towards a sealing position by the slider ( 5 ) when the slider is moved towards the closure position of the bag, and that said abutment means ( 6 ) are located in the vicinity of said bosses ( 53 , 54 ). 
   
   
       3 . The bag according to  claim 1 , further comprising additional abutment means ( 6 ) located on said sheets ( 12 ,  13 ) inside said slider ( 5 ), i.e. on the side of its inner space. 
   
   
       4 . The bag according to  claim 1 , wherein said abutment means ( 6 ) comprises a bulge which protrudes at the surface of each of said sheets ( 12 ,  13 ) and which extends parallel to the displacement axis (X-X′) of the slider. 
   
   
       5 . The bag according to  claim 1 , wherein said bulge ( 6 ) is continuous. 
   
   
       6 . The bag according to  claim 4 , wherein said bulge ( 6 ) is discontinuous, i.e. formed with a series of sections, the largest interval (l 2 ) between two neighboring sections being smaller than the longitudinal dimension (l 1 ) of said slider. 
   
   
       7 . The bag according to  claim 1 , wherein said abutment means ( 6 ) are made with said sheets in the same material. 
   
   
       8 . The bag according to  claim 1 , wherein said abutment means ( 6 ) are components added to said sheets.
