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.
