Abstract

A covering member (1; 1′; 1″) for mounting on a fastener ring (2), the ring and the covering member co-operating with each other to form a fastener device for fastening a dispenser system (3), such as a pump or a valve, on a receptacle neck (40), the covering member presenting a general configuration that is substantially cylindrical and that includes an outside wall (14) and an inside wall (15) for coming into clamping contact around the ring (2), the inside wall forming projections (17) that project inwards from a base zone (151), the projections being disposed as elongate ribs (16; 16′; 16″), the covering member being characterized in that each rib is formed by a plurality of projections (17) that are separated by gaps (18) in such a manner as to form a projecting rib that is interrupted locally.

Claims

1. A fastener device comprising a fastener ring (2) and a covering member (1;

1′

;

1″

) for mounting on the fastener ring (2), the ring configured to be engaged around a receptacle neck (40) for fastening a dispenser system (3), the covering member presenting a general configuration that is substantially cylindrical and that includes an outside wall (14) and an inside wall (15) for coming into clamping contact around the ring (2), the inside wall forming projections (17) that project inwards from a base zone (151) that is cylindrical, the projections are disposed as elongate vertical ribs (16;

16′

;

16″

) oriented relative to an upright orientation of the receptacle and substantially parallel to an axial direction of the covering member, each rib being formed by a plurality of vertically elongate projections (17) that are separated by gaps (18) in such a manner as to form a projecting rib that is interrupted locally and extending vertically and wherein the ribs extend parallel to each other.

2. A covering member according to claim 1, in which the projections (17) of the rib are vertically elongate relative to the upright orientation of the receptacle in the longitudinal direction of the rib, each of the projections forming two ends (171) and two long vertical edges (172), the adjacent ends of two projections being separated by a gap (18).

3. A covering member according to claim 1, in which the gaps (18) are made by displacing material, such that each gap is bordered by lumps of displaced material (175, 176).

4. A method of manufacturing a covering member according to claim 1, the method comprising the following successive steps:

a) making a covering member by stamping metal in such a manner as to form continuous ribs on the inside wall; and

b) machining the ribs by removing material so as to form gaps that divide each rib into a plurality of separate projections.

5. A method of manufacturing a covering member according to claim 3, the method comprising the following successive steps:

a) making a covering member by stamping metal in such a manner as to form continuous ribs on the inside wall; and

b) machining the ribs by displacing material so as to form gaps that divide each rib into a plurality of separate projections.

6. A method according to claim 5, in which the machining step is performed by embossing or by knurling.

7. A fluid dispenser comprising a receptacle, a dispenser system, and a fastener device that integrates a covering member according to claim 1.

8. The covering member according to claim 1, wherein the plurality of projections that form each rib extend serially one after the other to define a linear track that makes up the rib.

9. The covering member according to claim 1, wherein the plurality of projections that makes up one of the ribs is non-annular.

10. The covering member according to claim 1, wherein the plurality of projections that makes up one of the ribs are broken longitudinally to form the gaps.

11. The covering member according to claim 1, wherein the dispenser system is a pump or a valve.

12. A fastener for fastening a dispenser system to a receptacle, comprising:

a fastener ring;

a covering member configured to mount on the fastener ring;

the fastener ring-configured to engage around a neck of the receptacle to fasten the dispenser system to the receptacle;

the covering member comprises an outside wall and an inside wall sized so that the inside wall engages and clamps around an outer surface of the fastener ring;

the inside wall of the covering member comprising projections that project from a base zone, the projections are elongated with a length longer than a width and oriented vertically along the length relative to an upright orientation of the receptacle, groups of the projections are disposed vertically one after another with gaps between vertically adjacent projections, each group of projections forming a vertically oriented rib interrupted locally by the gaps, the rib extending parallel to each other and to an axial direction of the covering member.

13. The fastener according to claim 12, wherein the ribs extend parallel to each other along the circumference of the inside wall of the covering member.

14. The fastener according to claim 12, wherein the gaps provide axial retention of the covering member as a result of material from the fastener ring creeping into the gaps.
