Abstract: The invention relates to 2 closure kit comprising two extra elements (200, 250) which can successively engaged and separated, and a cursor (100) comprising a base (110), two lateral side plates (120, 130), a central wall (140) and a sole (142) linked to the central wall (140), characterized in that at least one of the two elements (200, 250) comprises a structure (210, 260) forming a stop for the sole (242) in order to prevent doe cursor (100) from retreating as a result of the effect of a stair tending towards tearing.

Abstract: The invention relates to a sachet closure assembly, the sachet thus obtained and the associated production method and machine. The inventive closure assembly consists of two sections (100, 200) of thermoplastic material, comprising complementary elements (110, 210) which are adapted to be alternately engaged, such that the sachet can be closed, and separated, such that the sachet can be opened and the contents thereof accessed. The aforementioned complementary elements (110, 210) are borne by respective support webs (100, 200). The invention is characterised in that one, and only one, of the support webs (100, 200) comprises ridges (130, 230) which project out from the inner surface thereof, said inner surface facing the other web.

Abstract: A bag having closure profiles combined with a slider, wherein an end weld made between the closure profiles is shaped according to a geometry, which is the complement of the slider. Preferential shaping of the weld can be accomplished by pressing the slider on the weld, in a hot welding state, in order to mold the weld in the slider.

Abstract: The invention relates to a closure assembly (1) comprising complementary closure sections (2) and panels (6a, 6b) for fixing said closure assembly to the internal faces of a bag. The inventive assembly is characterised in that it comprises: sealing bands (11, 13) which are disposed on the external faces of the fixing panels (6a, 6b); a precut or line of weakness (10) which is made in one of the fixing panels (6a) and which divides said panel (6a) into a first external part (61a) and a second internal part (62a), the sealing band on the panel being limited to the external part of same; and a sealing band (12) which is disposed on the internal face of at least one of the panels, each internal sealing band being disposed on the internal part of the fixing panels.

Abstract: Reclosable bag (1) comprising two walls (2, 3) forming a mouth (5) on which are fixed bag opening and closing means (8), an actuating slider (7) for the said means (8), means (6) forming opening indicator means, characterized in that the opening indicator means (6) comprise an adhesive strip bonded to an external surface of the opening and closing means (8) and of the actuating slider (7).

Abstract: The present invention relates to a bag having closure profiles combined with a slider (20), characterized in that an end weld (3) made between the closure profiles is shaped according to a geometry which is the complement of the slider (20).
