Abstract (en)

[origin: EP0304387A2] the closure for tubular containers according to the invention is of the kind comprising a pan shaped lid (1) fitting on the inside of the container mouth (4) to be closed. According to the invention the border (3,23) of the mouth of the container (4) is formed with an internal thickening (2,20) extending on at least a portion of its contour, whereas the lid (1) has a side wall the outer surface of which fits with the thickening inner surface, a radial flange (5) extending outwards of its edge, intended to rest upon the edge (3a) of the container mouth, and a rim (6) extending outwardly about its bottom and having a saw tooth shaped cross section intended to be locked against the lower edge (7,22) of the border inner thickening, thus preventing an involuntary removal of the lid. The inner thickening (2) of the container mouth opening may be formed by folding inwardly the border (3) onto itself, or by a hoop (20) formed with a channel shaped transverse cross section fitting on the border (23) of the container opening to be closed, such that the said border is trapped between the internal faces of the channeled hoop.
