  • the so-called 1-inch aerosol mounting caps have a side wall diameter of 24.892 to 25.146 mm (0.980 to 0.990 "). It has been shown that sealing material with a thickness of 0.432 mm (0.017") is sufficient. Mounting caps with a side wall diameter of 24.13 mm (0.950 ”) were used to adapt to this sealing material thickness. Sealing tapes with a width of 7.14 mm (9/32”) were satisfactory.
  • any plastic sealing material made of plastic with sufficient elasticity can be used, provided there is compatibility between the container contents and the plastic, it has been found that a plastic which is a low density polyethylene (a density in the range 0.916 to 0.922), the 5 to 15% polyisobutylene in the molecular weight range of 40,000 to 200,000 and stabilizers, which are usually used for polyethylene in an environment in which the sealing material is, results in a satisfactory sealing material in a wide range of products.
  • annular ribs instead of only one annular rib in the sealing ring, it is also possible to use a plurality of ribs in the radial direction across the width of the sealing ring. Furthermore, several annular ribs can also be provided be, since it has been shown in principle that a discontinuity in the flatness or smoothness of the sealing ring, as caused by a ribbed design, gives the sealing ring resistance to loosening during filling or displacement on the mounting cap, namely in that the Seal returns to its initial feed position. 13 shows a mounting cap provided with a seal according to the invention in perspective.
  • the sealing cap In contrast to mounting caps, which are provided with sealing material only along the side wall part of the cap, the sealing cap has a better sealing effect due to the fact that the sealing material extends from the pinching point between the cap and the flange edge of the container and into the channel. Furthermore, the seal of the mounting cap according to the invention has a substantially uniform thickness even before it is flanged to the container, while the known seal formed by injection is non-uniform because it tapers towards the outer edge of the channel and to the transition point between the side wall and the channel. A uniform thickness results in a better sealing effect.
