Abstract
A fastener system for releasably fastening a dispenser member on a reservoir neck, the system having a fastener ring including flexible axial tabs for fastening around the reservoir neck, the tabs separated by axial slots; and a locking sleeve engaged around the fastener ring to lock the tabs in engagement around the neck. The sleeve forms a plurality of locking sectors that engage the tabs to lock them around the neck and a plurality of non-locking sectors not in contact with the ring. The sleeve is movable about the ring between an assembled position and a disassembled position in which the locking sectors are situated at the slots so as to enable the tabs to deform in order to disengage from the neck.

A fastener system for releasably fastening a dispenser member, such as a pump or a valve, on a reservoir neck, the system comprising:
- a fastener ring including both reception means for receiving the dispenser member, and fastener means that are suitable for coming into engagement with the reservoir neck, the fastener means including flexible axial tabs that are suitable for fastening around the reservoir neck, the tabs being separated by axial slots;
- and
- a locking sleeve that is engaged around the fastener ring so as to lock the tabs in engagement around the neck;
- the locking sleeve forms a plurality of locking sectors for coming into engagement with the tabs so as to lock them around the neck, and a plurality of non-locking sectors not in contact with the ring, the sleeve being movable about the ring between an assembled position in which the locking sectors are in engagement with the tabs and the non-locking sectors are situated at the slots, and a disassembly position in which the locking sectors are situated at the slots and the non-locking sectors are situated at the tabs so as to enable the tabs to deform in order to disengage from the neck.
A fastener system according to any preceding claim, wherein the ring comprises:
