Abstract

A method of assembling a fluid dispenser device, the method comprising the following steps:
pre-assembling a first unit comprising a body ( 10 ) and a lateral actuator system ( 40 ), said lateral actuator system including a presser element ( 42 ) that is mounted on the body ( 10 ) to pivot about an axis (A), an actuator element ( 41 ) being mounted on said presser element ( 42 ) to pivot about an axis (B), said presser element ( 42 ) having a pre-assembled position in which said lateral actuator system ( 40 ) is blocked; assembling a second unit, comprising a dispenser member ( 30 ), such as a pump or a valve, that is mounted on a reservoir ( 20 ) by means of a fastener ring ( 60 ), in said first pre-assembled unit; and moving said presser element ( 42 ) from its pre-assembled position to a final assembled position that is axially offset from said pre-assembled position, and in which said actuator element ( 41 ) co-operates operationally with said fastener ring ( 60 ) so as to actuate said dispenser member ( 30 ) each time the lateral actuator system is actuated.

First claim

The invention claimed is:

1. A method of assembling a fluid dispenser device, the method comprising the following steps:
pre-assembling a first unit comprising a body and a lateral actuator system, said lateral actuator system including a presser element that is mounted on the body to pivot about a first axis, an actuator element being mounted on said presser element to pivot about a second axis, said presser element having a pre-assembled position in which said lateral actuator system is blocked;
assembling a second unit, comprising a reservoir, containing a fluid, and a dispensing pump that is mounted on said reservoir by means of a fastener ring, in said first pre-assembled unit; and
moving said presser element from the pre-assembled position to a final assembled position that is axially offset from said pre-assembled position, and in which said actuator element co-operates operationally directly with said fastener ring so as to actuate said dispensing pump each time the lateral actuator system is actuated;
wherein said body includes a bottom portion, said presser element being moved from the pre-assembled position to the assembled position by assembling said bottom portion in said body.

2. A method according to claim 1 , wherein said lateral actuator system is blocked in the pre-assembled position of said presser element.

3. A method according to claim 2 , wherein said presser element includes a pre-assembly portion that is adapted to co-operate with a blocking portion of the body in the pre-assembled position, so as to block said lateral actuator system, said pre-assembly portion no longer co-operating with said blocking portion when said presser element is moved from its pre-assembled position to its assembled position.

4. A method according to claim 1 , wherein said actuator element includes a resilient element that co-operates with said presser element so as to urge an end of said actuator element away from said presser element.

5. The method according to claim 4 , wherein the resilient element is a resilient blade.

6. A method of assembling a fluid dispenser device, the method comprising the following steps:
pre-assembling a first unit comprising a body and a lateral actuator system, said lateral actuator system including a presser element that is mounted on the body to pivot about a first axis, an actuator element being mounted on said presser element to pivot about a second axis, said presser element having a pre-assembled position in which said lateral actuator system is blocked;
assembling a second unit, comprising a reservoir, containing a fluid, and a dispensing pump that is mounted on said reservoir by means of a fastener ring, in said first pre-assembled unit; and
moving said presser element from the pre-assembled position to a final assembled position that is axially offset from said pre-assembled position, and in which said actuator element co-operates operationally directly with said fastener ring so as to actuate said dispensing pump each time the lateral actuator system is actuated; and
wherein said actuator element includes at least one radial projection having a top edge that, during actuation, comes into contact with a bottom edge of a radial flange of the fastener ring, said radial projection of said actuator element being assembled below said radial flange when said presser element is moved from its pre-assembled position to its assembled position.

7. The method according to claim 6 , wherein said presser element includes a pre-assembly portion that is adapted to co-operate with a blocking portion of the body in the pre-assembled position, so as to block said lateral actuator system, said pre-assembly portion no longer co-operating with said blocking portion when said presser element is moved from the pre-assembled position to the assembled position.

8. The method according to claim 6 , wherein said actuator element includes a resilient element that co-operates with said presser element so as to urge an end of said actuator element away from said presser element.

9. The method according to claim 8 , wherein the resilient element is a resilient blade.
