a cylindrical covering member mounted on the fastener ring, the ring and the covering member cooperating with each other to form a fastener device for fastening a dispenser system to a neck of the receptacle, the covering member includes an outside wall and an inside wall for coming into clamping contact around the ring, the inside wall comprising:
an array of grooves including a plurality of elongate longitudinal groove segments interlaced by an array of non-groove zones, a portion of the plastic fastener ring creeping into the elongate groove segments of the inside wall of the covering member.
2. The covering member assembly according to claim 1 , wherein the elongate groove segments are disposed substantially horizontally, forming interrupted annular grooves.
3. The covering member assembly according to claim 1 , wherein the elongate groove segments are made by displacing metal material from the inside wall, such that each segment is bordered by lumps of displaced metal material.
4. A fluid dispenser assembly comprising the receptacle, the dispenser system, and the fastener device in combination that integrates the covering member according to claim 1 .
5. The covering member assembly according to claim 1 , wherein the elongate groove segments extend serially to define a discontinuous track.
6. The covering member assembly according to claim 1 , wherein the at least one elongate groove is broken longitudinally by the non-groove zones.
7. The covering member assembly according to claim 1 , each groove segment has two ends and two long edges, wherein the two ends of each elongate groove segment are respectively interconnected by the corresponding two long edges.
8. A covering member assembly comprising: a plastic fastener ring to be secured to a receptacle;
a cylindrical covering member mounted on the fastener ring, the ring and the covering member cooperating with each other to form a fastener device for fastening a dispenser system to a neck of the receptacle, the covering member includes an outside wall and an inside wall for coming into clamping contact around the ring, the inside wall comprising:
an array of grooves including a plurality of elongate lateral groove segments arranged in a series of rows and columns interspersed by non-groove zones, a portion of the plastic fastener ring creeping into the elongate groove segments of the inside wall of the covering member.
