Abstract
A dispenser member such as a pump or a valve, comprising: a body (2) in which a piston (3) is slidably received and in which a ferrule (4) is engaged; and fixing means (5) comprising at least one peripheral projection (53) that projects radially outwards, said projection (53) serving to come into engagement in a notch (82) formed in an inside wall (81) of the neck (80) of a receptacle (8), said projection (53) being elastically displaceable radially inwards so as to come into engagement in the notch (82) in the neck by elastically deforming the body (2) radially inwards in a deformation zone (200); said dispenser member being characterized in that the ferrule (4) is not in contact with the body at the deformation zone (200) of the body (2).
Claims13
A dispenser member such as a pump or a valve, comprising:
- a body (2) in which a piston (3) is slidably received and in which a ferrule (4) is engaged;
- and
- fixing means (5) comprising at least one peripheral projection (53) that projects radially outwards, said projection (53) serving to come into engagement in a notch (82) formed in an inside wall (81) of the neck (80) of a receptacle (8), said projection (53) being elastically displaceable radially inwards so as to come into engagement in the notch (82) in the neck by elastically deforming the body (2) radially inwards in a deformation zone (200);
- said dispenser member being characterized in that the ferrule (4) is not in contact with the body at the deformation zone (200) of the body (2).
A method of fixing a dispenser member such as a pump or a valve, said dispenser member comprising:
- a body (2) in which a piston (3) is slidably received and in which a ferrule (4) is engaged;
- and
- fixing means (5) in which the body (2) is received, said fixing means comprising at least one peripheral projection (53) that projects radially outwards, said projection (53) serving to come into engagement in a notch (82) formed in an inside wall (81) of the neck (80) of a receptacle (8), said projection (53) being elastically displaceable radially inwards so as to come into engagement in the notch (82) in the neck by elastically deforming the body (2) radially inwards;
- said method comprising the step of exerting sufficient pressure on the fixing means (5) to bring the projections (53) into the notch (83) in the neck.
