Definitions

  • a spacer portion may be provided between the U-shaped portion and the threads 130, which has a constant-diameter cylindrical profile.
  • the first face 110a of the metal body 110 may have different profiles.
  • Figure 8b shows an example in which the first face 110a has a substantially corrugated profile with outward concavities to create a depression in the first face 110a of the metal body 11a substantially at a central area thereof.
  • diameter d 1 of the tubular wall 120 is intended to indicate the exterior diameter of the exterior portion 120d.
  • the interior diameter d 2 of the cap 100 may be selected according to the diameter of the container.
  • the seal 115 is made of polymeric material and may be integrally joined to the bottom 111 of the cap, preferably by press fitting the edge of the seal 115 against the surface of the inner portion 120c of the tubular wall 120.
  • the seal 115 is formed by pouring a liquid polymeric material 111 onto the bottom 111 of the cap 100.
  • the polymeric material is poured at the end of the process for forming the cap 100, after threading, as described hereafter.
  • the process of the invention includes the step of:
  • the steps d) and e) are carried out after the step a2) of deep-drawing the metal sheet 110 to obtain the tubular wall 120.
