Definitions

  • the present invention relates to the field of flexible tubes comprising a cap closing off the neck prior to the first use of the tube, and a perforating cap suitable for piercing the cap.

  • a stopper the punch of which allows partial cutting of the cover.
  • tubes have already been proposed with which three turns are necessary to go from a position where the punch is flush with the cover to an end-of-travel position. During these three turns, the cap is pierced and then gradually sheared to achieve the desired partial cut.
  • said plug is configured to go from a position in which said teeth are flush with said cover, called flush position, to a position in which said teeth have pierced said cover, called piercing position, then from said position drilling at an end-of-travel position allowing partial cutting of said cover, the passage from said drilling position to said end-of-cut position being effected with an angular amplitude of rotation of less than 360 °.
  • the invention is based on the observation made by the applicant that it is possible to obtain a cutout of a cover with a reduced number of turns of the stopper by distinguishing between the angular amplitude necessary to pierce the cover, which will essentially depend on the elasticity of the latter, and the angular amplitude useful for cutting.
  • an angular cutting amplitude of less than 360 ° a partial, rapid and clean cutting of the cap is obtained when the tube is used for the first time. This facilitates the handling of the assembly by the user, in particular by saving time for cutting the cover.
  • stopper is understood to mean an object enabling a receptacle to be sealed off, in particular an outlet opening for a product, in a reversible manner.
