Abstract: A slider for actuating profiled closure tracks, especially for a bag, having a base and two flanks parallel to a median central longitudinal plane and configured for stressing the profiled closure tracks between a closed latch position and an open separated position. A longitudinal rib subdivides the internal space of the slider into two non parallel channels. A first axial end of the channels wherein the channels are convergent makes an input end of the channels, while a second axial end of the channels wherein the channels are divergent makes an output end of the channels.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention particularly relates to a device for placing a slider (1) for actuating closure profiles (P1, P2) of a bag (S), that includes a base, two flanges, and means adapted for respectively urging said closure profiles (P1, P2) towards each other or away from each other on a bag (s), wherein said device includes at least one clamp for retaining the profiles (P1, P2) as well as means for urging a slider (1) towards means (5) for temporarily spacing the flanges of the slider (1), said spacing means including cam paths with a rising slope, characterised in that said means include stowable cams (5) that, in a first non-stowed position interact with said slider (1) so that, during a movement thereof, the inner surface of its flanges is brought into contact with the cam paths progressively moving the same away from each other, and that, in a second stowed position, no longer interact with the slider (1) so that said flanges are brought together.

Abstract: The present invention relates to a closing device for sachets comprising at least two complementary closing elements (200, 300) and an associated slider (100) comprising a central bead (140), adapted for modifying the joining state of said two elements (200, 300) so as to respectively separate or engage the latter according to its direction of motion, characterized in that the slider (100) comprises at least one flexible lip (145, 146) placed on the apex of the central bead (140) opposite a lead angle (216, 316) provided on the closing element (200, 300), according to a configuration such that any attempt to pull back the slider results in autolocking hanging of the lip (145, 146).

Abstract: The invention particularly relates to a slider (1) for actuating closure profiles (P1, P2), in particular for a closing assembly on a bag (S), that includes a base (10), two flanges (11, 12), and means adapted for respectively urging said closure profiles (P1, P2) towards each other or away from each other, depending on the slider movement direction along the profiles (P1, P2), in order to move the profiles (P1, P2) between a closed latched position and an open separated position, as well as protruding urging spigots (4) on said flanges (11, 12) in the vicinity of the end thereof opposite said base (10) in order to temporarily open the same and facilitate the engagement thereof onto said profiles (P1, P2) when a force is applied on said spigots (4). The slider is characterised in that said means includes means for receiving protrusions (T1, T2) associated with said profiles.

Abstract: The invention notably relates to a sachet comprising a body, the inner space of which is notably delimited by two sheets (10, 11) forming its main walls, and which includes complementary closing profiles respectively attached on these sheets (10, 11) as well as a cursor (4) for actuating the profiles upon closing and opening, which comprises two longitudinal flanks (41, 42) connected by a base (40), as well as a longitudinal sole which extends from the base (40) between the flanks (41, 42), in order to delimit two opening/closing channels of the profiles. It is remarkable in that said cursor (4) includes, longitudinally, in the extension of said base (40), a jutting-out element (5) which extends beyond said flanks (41, 42), this element (5) being positioned on the side of the cursor (4) which corresponds to the closing direction of said profiles.

Abstract: Poultry packed in a crate suitable for the transport of live poultry are passed into a chamber having an oxygen depleted atmosphere and held in the atmosphere for a sufficient period of time for the poultry first to lose consciousness and then to die as a result of the lack of oxygen in the atmosphere. The atmosphere typically comprises nitrogen or argon containing less than 1% by volume of oxygen. It is found that the birds so slaughtered exhibit less bone damage than poultry slaughtered by a conventional method including the step of electrically stunning the birds prior to slaughter.
