Definitions

• the present invention relates to the field of sachets comprising slider-actuated closure devices.
• the bag closure devices generally comprise two complementary male / female type profiled elements or complementary hook type designed to allow multiple successive openings / closings.
• the purpose of the slider is to facilitate engagement and separation of the profiles, respectively.
• the cursor 100 generally comprises a base 110 which carries two lateral flanges 120, 130 and a central wall 140.
• the flanges 120, 130 and the wall 140 define in combination two channels 150, 160 partly at less non-parallel. These channels receive respective elements linked to the two sections 200, 250.
• FIGS. 3, 4 and 5 It has also been proposed as illustrated in FIGS. 3, 4 and 5 to place a sole 142 on the end of the central wall 142.
• the sole 142 is intended to take position under the profiles 200, 250 as seen in FIGS. 4 and 5.
• this solution is not entirely satisfactory. Indeed, the sole 142 must have a tapered shape in the direction of the convergence of the channels 150, 160 so as not to disturb the closure of the bag. It is thus found in practice that the risk of the cursor tearing off remains, in particular by pivoting and extraction by the tapered end of the sole which acts in the manner of a wedge urging the spacing profiles.
• the aim of the present invention is to improve the known devices by limiting the risk of the cursor being torn off.
• a closure assembly comprising two complementary elements capable of being successively engaged and separated, and a slider comprising a base, two lateral flanges, a central wall and a linked sole to the central wall, characterized in that at least one of the two elements has a concave structure towards the inside of the bag forming a stop for the sole to prevent the withdrawal of the cursor under the effect of a pull-out stress .
• the present invention also relates to sachets equipped with such a closure assembly.
• FIG. 1 previously described represents a schematic perspective view, partially exploded, of a known closure assembly conforming to the state of the art
• FIG. 2 previously described represents a cross-sectional view of this same closure assembly
• FIG. 3 previously described shows a partially exploded perspective view of a cursor according to the state of the art
• - Figures 4 and 5 previously described represent two sectional views of a closure assembly equipped with such a cursor according to two planes referenced IV-IV and VV in FIG. 3,
• FIG. 6 represents a cross-sectional view of a closure assembly in accordance with the present invention at the tapered end of the sole
• the present invention can find application in any type of sachets. For this reason, we will not describe in detail below the means of producing the bag itself, or its constituent material or materials.
• closure profiles 200, 250 They are not limited to the geometry shown in the appended figures. These profiles can be of the complementary male / female type, of the complementary hook type, of the velvet / complementary hook type, or any other equivalent structure. They can be made of any suitable material.
• the closure profiles 200, 250 may have come in one piece with the walls of the bag, for example from extrusion or attached and fixed to the walls of the bag by any suitable means.
• the cursor 100 can be made of metal or plastic. It comprises a base 110, two lateral flanges 120, 130 and a central wall 140 which carries a sole 142.
• the lateral flanges 120, 130 and the central wall 140 define in combination two channels 150, 160 at least partly non-parallel.
• at least one of the two complementary elements 200, 250 of the closure assembly has a structure 210 forming a stop for the sole 142.
• - has a concavity directed towards the inside of the sachet, and / or
• - defines at least one surface which converges towards its support wall in the direction of the outside of the bag and / or - defines at least one longitudinal rib serving for attachment to the sole in the event of an attempt to tear off.
• FIG. 6 shows such a structure 210 forming a generally rounded concave stop on one of the closure sections 200 opposite a complementary rounded convex geometry formed on the sole 142.
• FIG. 7 shows a similar arrangement in which the structure 210 has the overall shape of a concave dihedral opposite a convex dihedral formed on the sole 142.
• FIG. 8 shows a variant according to which surfaces forming an abutment are formed respectively on the two closing elements 200, 250, under the references 210, 260.
• the sole 142 defines a complementary concave dihedron.
• FIG. 9 shows a variant according to which the structures forming a stop are independent of the closure profiles themselves. This provision can apply to all of the variants according to the invention.
• Figures 10 and 11 two variants according to which the structures forming a stop are provided on the outer side of the closure profiles 200, 250. This arrangement prevents the wall 140 and the associated sole 142 from passing between the closure profiles 200, 250. It therefore guarantees sealing.
• FIG. 12 shows an alternative embodiment according to which several stages of stop means 210, 260 are provided respectively opposite several associated stages of the sole
