Embodiment Construction

[0030] Reference is made to a first advantageous embodiment of the invention figure 1 with 2 , the fluid product dispensing device includes a body 10, and a reservoir 20 for containing a fluid product, especially medicine, for being sprayed into a user's nose is assembled in the body 10. A dispensing mechanism 30 , such as a pump or a valve, is assembled on said reservoir 20 , advantageously by means of a retaining ring 60 . The distribution mechanism includes: a distribution mechanism main body 31 such as a pump body or a valve body; and a movable member 35 slidably installed in the distribution mechanism main body, such as a piston rod or a valve. The movable member 35 penetrates deep into the dispensing mechanism body 31 in a conventional manner to actuate said dispensing mechanism 30 . This is shown very schematically in the figure, where the movable member 35 is in figure 1 , 3 , 5 and 7 are at a high position (rest position) and in figure 2 , 4 , 6 and 8 are in th...

Abstract

A fluid dispenser device including a body, a reservoir, a dispenser head, and a dispenser member. The dispenser member includes a dispenser-member body and a movable member that moves axially in the dispenser-member body during actuation. The device includes a lateral actuator system secured to the body and having an actuator element that co-operates with the reservoir, with the dispenser member, or with an element secured to the reservoir and / or the dispenser member. The actuator element is movable between a rest position and an actuated position. The body includes a guide surface for guiding the actuator element, the guide surface is stationary relative to the dispenser head, and substantially parallel to the movement axis of the movable member in the dispenser-member body during actuation.

Description

technical field [0001] The present invention relates to fluid product dispensing devices, and more particularly to nasal spray devices for pharmaceuticals. Background technique [0002] Fluid dispensing devices are well known in the art. They generally comprise a reservoir containing a fluid product on which a dispensing mechanism, such as a pump or a valve, is assembled, the dispensing mechanism being actuated, typically through a dispensing head, in order to dispense the product contained in said reservoir in a selective manner. The dispensing head comprises a dispensing orifice through which the product is to be sprayed, for example into the user's nose in the case of a nasal spray device. Many such devices are manually activated by the user, causing the reservoir and dispensing head to move axially relative to each other, which actuates the dispensing mechanism. However, such devices have some disadvantages, especially when the device is of the nasal spray type, since ...
