This present invention concerns a closure assembly that has two complementary elements which are capable of being successively joined and separated, and a slider that includes a base, two lateral walls, a low central ridge and a soleplate connected to the low central ridge, characterized by the fact that at least one of the two elements has, on its inside surface, a structure that is capable of being pressed against the soleplate under the effect of a pulling force so that, under the effect of this force, the said element tends to be flattened against the associated lateral wall of the sider.

Device intended for the closure of bags which includes resources that resist the pulling-off of a slider, and bag that is so equipped

A sachet has a body, the inner space of which is notably delimited by two sheets forming its main walls, and which includes complementary closing profiles respectively attached on these sheets as well as a cursor for actuating the profiles upon closing and opening, which comprises two longitudinal flanks connected by a base, as well as a longitudinal sole which extends from the base between the flanks, in order to delimit two opening/closing channels of the profiles. The cursor includes, longitudinally, in the extension of the base, a jutting-out element which extends beyond the flanks. The jutting-out element is positioned on the side of the cursor which corresponds to a closing direction of the profiles.

A slider actuates profiled closure shapes for a closure assembly equipping a sachet. The slider includes a base, two flanks, means adapted for stressing respectively said profiled closure shapes, by moving towards or moving away according to a direction of displacement of the slider along the profiled closure shapes, such that the profiled closure shapes are movable between a closed latch position and an open separated position, and a stiffening bar extending along a longitudinal free edge of each of the two flanks. The stiffening bar has a greater thickness than a thickness of its respective flank, extends over an external face of its respective flank, is made from a piece with its respective flank, and has a same longitudinal range as its respective flank.

Slider for actuating profiled shapes with stiffening bars

The present invention relates to a closing device for sachets comprising at least two complementary closing elements () and an associated slider () comprising a central bead (), adapted for modifying the joining state of said two elements () so as to respectively separate or engage the latter according to its direction of motion, characterized in that the slider () comprises at least one flexible lip () placed on the apex of the central bead () opposite a lead angle () provided on the closing element (), according to a configuration such that any attempt to pull back the slider results in autolocking hanging of the lip ().

Closing device with slider for sachet, comprising anti-engagement means

A slider chain including a plurality of sliders joined together by divisible bridging pieces (), and including a linking device at each end in order to interconnect the ends of two slider chains so as to form a longer chain overall. The sliders include an attachment mechanism which is not of cylindrical revolution.

Slider chains

A method for the manufacture of packaging bags, which includes a step of forming at least one bag in a scrolling film, welding opening and closing zippers that include a series of operating sliders onto the scrolling film, and effecting at least one cut in the zippers, where the length of the cut is greater than the length of each slider.
