  • the profiles defined on the one hand by the internal surfaces and on the other hand by the external surfaces of portions 661 and 662 are curved lines.
  • FIG. 15 shows a capsule 1 in which, for a single protuberance 6 , sections 67 and 68 are separated by an angle ⁇ i of 80 degrees, defined around axis X 1 .
  • the protuberances 6 together cover an angular area equal to 320 degrees around the axis X 1 .
  • this angular area is wider than in the first embodiment, the risk of the punch of the machine bearing on a space between two protuberances 6 is lower. In other words, the punching of the protuberances 6 is facilitated.
  • FIG. 16 shows a capsule 1 in which internal intermediate sections 69 of localized weakening are formed between the sections 67 and 68 of two neighboring protuberances 6 , in the continuation of sections 65 .
  • the punching of the protuberances 6 is facilitated.
  • FIG. 17 shows a capsule 1 having a single breakable protuberance 6 , having an annular shape centered on the central axis.
  • this breakable protuberance covers an angular area of 360 degrees around the axis X 1 .
  • a single section 65 and a single section 66 having circular shapes extend all around axis X 1 .
  • the section 65 may be a circular line of localized weakening, like section 66 .
  • Such a capsule 1 is well-suited to certain types of machines.
  • the capsule 1 may be adapted in terms of cost, functionality and performance.
