Definitions

• FIG. 1 does not teach to carry out crimping at the level of the re-entrant flap, for the simple reason that there is no flap re-entering on the covering hoop of FIG. 1 Consequently, the technical problem which underlies the present invention (reduced hoop wall thickness) is not mentioned in this document of the prior art. Therefore, the simplest and most logical solution is to crimp the cover band in the same place as that of Figure 1, namely on its outer cylindrical part
• This rod 41 is located on the upper end of the neck 4 from which it projects upwards.
• the O-ring 3 according to the invention has an internal diameter such that its lower internal edge 31 comes into sealing contact with a possible deformation on the outside of the rod 41.
• the edge inner bottom 31 of the seal 3 is deformed against the rising outer slope of the rod 41, which contributes to a perfect seal at this location.
• the upper outer edge of the seal 3 is also deformed against the corner formed by the connecting flange 113 and the skirt 114.
• a perfect seal is obtained.
• the seal 3 does not extend between the ring 41 and the connecting flange 1 13, it does not create an allowance at this location so that the fixing ring can come into direct contact with the ring 41 , which contributes to reducing the total height of the dispenser.
