Problems solved by technology

These lateral actuation devices usually include movable members that impose a clearly defined direction of actuation, with the risk of poor functioning in case of actuation in a slightly deviated direction
These laterally actuated devices produce noise when actuated or if the device is shaken, which is perceived as a negative by the user
The assembly of these lateral actuation devices is also usually complex, which is usually only possible after filling with the product to be dispensed, requiring a complex assembly line at the active product producer, which is usually different from the lateral Actuated Assembly Producer

Embodiment Construction

[0023] With reference to the example showing an advantageous first embodiment Figure 1 to Figure 3 , the fluid product dispensing device comprises a main body 10, in which a reservoir 20 is fitted, the reservoir 20 contains a fluid product, in particular a medicinal product, for spraying into the nasal cavity of a user. A dispensing mechanism 30, such as a pump or a valve, is mounted on the reservoir 20 with a retaining ring 60, which may be a crimped, snap-fit ​​or screwed retaining ring. The fixing ring 60 can be made of metal, such as aluminum, or of plastic material. As a variant, typically by overmolding, partly of plastic material and partly of metal, the retaining ring can be made of two materials. The dispensing mechanism includes a distributing mechanism main body 31, such as a pump body or a valve body, and a distributing mechanism 35, such as a piston rod or a valve member, which is installed so as to be axially slidable in the distributing mechanism main body. I...

Abstract

Disclosed is 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), the 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 the presser element (42) to pivot about an axis (B), the presser element (42) having a pre-assembled position in which the 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 the first pre-assembled unit; and moving the presser element (42) from its pre-assembled position to a final assembled position that is axially offset from the pre-assembled position, and in which the actuator element (41) co-operates operationally with the fastener ring (60) so as to actuate the dispenser member (30) each time the lateral actuator system is actuated.

Description

technical field [0001] The present invention relates to a method of assembling a laterally actuated fluid product dispensing device, in particular a nasal spray device for a medicinal product. Background technique [0002] Fluid dispensing devices are well known in the art. The device generally comprises a reservoir containing a fluid product, to which is fitted a dispensing mechanism, such as a pump or a valve, which is actuated, usually by means of a dispensing head, to selectively dispense the product contained in the reservoir. distribute. The dispensing head comprises a dispensing orifice, eg in the case of a nasal spray device, through which the product is sprayed into the nose of the user. Many devices of this type are manually actuated by the user by moving the reservoir and dispense head axially against each other so as to actuate the dispense mechanism. However, this type of device presents some disadvantages, especially when the device is of the nasal spray typ...
