Abstract:
The present invention relates to a closure device for bags or the like comprising two complementary profiled elements (110, 210), characterized in that it involves sequential squeezing (300), of the two engaged profiled elements (110, 210), in a direction perpendicular to the support webs (100, 200).
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:
A form-fill-seal machine and a method for manufacturing and filling a bag (100) having a drawstring tape or cord. The form-fill-seal machine includes a device to guide a film on the machine. A conveying device positions at least one drawstring tape or cord on the film. A folding device folds the film to form a first sheet and a second sheet of the bag. First and second welding jaws weld the first sheet and the second sheet to close two sides of the bag and leave a third side of the bag open. A filling chute fills the bag by the third side of the bag. Third welding jaws close the bag by sealing the third side.
Abstract:
The invention relates to a method for manufacturing (S) a bag (3) by means of blown film extrusion, including the following steps: extruding (S2) plastic such as to form an annular film (2) including closing assemblies (10, 20), said annular film being intended to form the walls of the bag; and blowing (S5) the annular film such as to form a sheath, the complementary profile sections (14, 24) of each of the closing assemblies (10, 20) being integrally formed with a base (18, 28) connected to the annular film (2) via a connection rod (19, 29) that extends parallel to the longitudinal axis (X) between the annular film (2) and the base (18, 28) and is designed to keep the base (18, 28) separated from the annular film (2).

The present invention relates to a closure device for bags or the like comprising two complementary profiled elements (110, 210), characterized in that it involves sequential squeezing (300), of the two engaged profiled elements (110, 210), in a direction perpendicular to the support webs (100, 200).
Abstract:
The invention relates to a bag (1) comprising:—two walls (10, 20),—two support webs (12, 22), each comprising at least one complementary section (3), an upper edge (12a, 22a),—two extension webs (14, 24), each comprising an upper part (14a, 24a) fixed to a respective wall (10, 20) of the bag (1) close to the mouth (5), and a lower part (14b, 24b) that is movable with respect to said wall (10, 20), the support webs (12, 22) being fixed to a respective wall (10, 20) by way of a respective extension web (14, 24) away from their upper edge (12a, 22a), such that the traction on the walls (10, 20) of the bag (1) when the complementary sections (3) are in contact causes the support webs (12, 22) to rotate about said complementary sections (3).
Abstract:
The present invention relates to a device for closing pouches or the like comprising a series of complementary parallel profiles (110a-110e, 210a-210e), said profiles being carried by respective supporting sheets (100, 200), characterised in that said device has sequential alterations (300) in at least one profile (110, 210) along a direction perpendicular to the supporting sheets (100, 200).
Abstract:
The invention relates to a form fill seal machine (200) for producing and filling a bag (100) with a band, said bag comprising a first sheet (112) and a second sheet (114) that together form a first edge (117) and a second edge (118) of the bag, and a band closing device (120), the machine comprising:—a device (210) configured to feed a film (1) onto the machine,—a conveying device (215) configured to position at least one band (136) on the film,—a folding device (240) configured to fold the film (1) in such a way as to form the first sheet (112) and the second sheet (114) of the bag,—welding jaws (245a, 245b) configured to weld the first sheet (112) and the second sheet (114) in such a way as to close two sides of the bag and leave a third side of the bag open,—a filling chute (250) configured to fill the bag via the third side of the bag, and—welding jaws (255) configured to close the bag by sealing the third side.

Abstract:
Sachet comprising: a first and a second wall (10, 20), a closure assembly (3) comprising a first and a second support web (30, 32) that are connected to the first and the second wall (10, 20), respectively, and each have a closure element (34), the first support web (30) being connected discontinuously along its length to the first wall (10) of the sachet (1) so as to form at least one passage (40) between this first support web (30) and the first wall (10) of the sachet (1) from the outside of the sachet (1), said passage (40) allowing local deformation of the first support web (30) for modifying the relative local orientation of the closure elements (34) while the walls (10, 20) are being moved apart and making it easier to separate the closure elements (34).
