Fastening system for a distribution member on a threaded neck of a reservoir

A fluid product distributor comprising:

• a reservoir for fluid product comprising a neck, a distribution member, such as a pump, and a fastening system;
• a fastening system fastened to the neck, the system comprising:
• a fastening ring and a rigid collar, the ring comprising a skirt intended to be engaged around the neck, the skirt comprising articulated fastening tabs angled outwards with respect to a central axis of the ring, the collar being able to be moved with respect to the skirt and engaged around the skirt so as to fold back the articulated tabs to the radial alignment thereof with the axis,
• wherein the ring with the collar is able to be assembled on the neck without relative movement between the ring and the collar, and the ring with the collar is able to be disassembled from the neck without relative movement between the ring and the collar,
• wherein the articulated tabs have an internal fastening means that can engage with an external fastening means of the neck.

A method for manufacturing a ring of a fastening system for fastening a distribution member, such as a pump, on a neck of a reservoir to form a distributor for a fluid product, the ring having a central axis and comprising a skirt intended to be engaged around the neck, this skirt comprising articulated fastening tabs having an internal fastening means that can engage with an external fastening means of the neck, said method comprising the following steps:

• moulding the ring on a core with the articulated tabs in the angled position with respect to the central axis and directed towards the outside of the skirt;
• lifting the articulated tabs until the tabs disengage with respect to the core;
• and,
• demoulding of the ring with one single straight translational movement.
