Bag including closing profiles actuated by a slider

Abstract

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

1 . A bag comprising:
 two generally parallel sheets forming main walls of the bag;   matching closing profiles respectively fixed on these sheets; and   a slider for actuating the profiles upon closing and opening,   wherein said slider comprises opposing flanks,   wherein each inner surface of the opposite flanks bears a boss directed towards the other opposite flank such that the sheets forming the main walls of the bag converge towards each other,   wherein the two generally parallel sheets comprise, on their respective outer faces and outside said slider, a bulge protruding from a surface of each of said sheets and extending parallel to a displacement axis of the slider   wherein the bulge is adjacent to the slider such that the bulges immobilize the two generally parallel sheets relative to said slider along a direction generally perpendicular to the displacement axis of the slider,   wherein the bag further comprises, inside said slider, additional raised relief sealing bulges that run parallel to said profiles, on the side of said sheets which face each other,   wherein the additional raised relief bulges are positioned on a side of the closing profiles that is inside the bag when in a closure position,   wherein the additional raised relief bulges are designed to provide a seal by forming a barrier between the sheets in the closure position of the bag, and   wherein said additional raised relief bulges are configured so as to be urged towards a sealing position by the slider when the slider is moved so as to cause the closure position of the bag,   wherein the distance between said bosses is smaller than the cumulated thickness of said relief sealing bulges,   and wherein the distance between said bulges and said additional raised relief bulges is slightly higher than the width of said bosses.   
     
     
         2 . The bag according to  claim 1 , further comprising additional abutment bulges located on said sheets in an inner space of the slider. 
     
     
         3 . The bag according to  claim 1 , wherein said bulge of each sheet is continuous. 
     
     
         4 . The bag according to  claim 1 , wherein said bulge of each sheet is formed with a series of discontinuous sections, and wherein a largest interval between two neighboring discontinuous sections is smaller than a longitudinal dimension of said slider. 
     
     
         5 . The bag according to  claim 1 , wherein said bulge of each sheet is made with its respective sheet in a same material. 
     
     
         6 . The bag according to  claim 1 , wherein said bulge of each sheet is a component added to its respective sheet.
