Problems solved by technology

When the applied axial pressure is relatively high, it is difficult to accurately control the position of the end point of the device including the dispensing mouth in the nostril, and the end of the dispensing head may hit the bottom of the nostril, which may cause pain to the user and / or pain
In addition, since the device requires a predetermined minimum force to operate, it may be difficult to use by elderly or people with limited mobility who have difficulty applying this force by placing the device in the nostril

Embodiment Construction

[0032] The invention will be made with reference to the three embodiments shown in the figures and relates to a double-dose fluid product dispenser, ie comprising two doses of the product to be dispensed, the product intended to be dispensed into the nasal cavity of the user. Of course the invention can also be used in single dose devices, ie comprising only one dose to be dispensed. Likewise, the invention may also be used in multiple doses comprising more than two doses, for example three or four doses. Additionally, the invention is not limited to nasal type dispensers.

[0033] refer to Figure 1-3 , shows the first embodiment of the present invention. In a first embodiment, the device comprises a reservoir 20 preferably formed by a glass tube 21 which is open at only one end and whose opening is blocked by a stopper-piston 25 . Thus, the reservoir 20 can be additionally filled with the product to be dispensed and then sealed closed with said bung 25, said filled reserv...

Abstract

The invention concerns a fluid product dispenser comprising a body (10), defining a dispensing orifice (11), and a reservoir (20) containing one or several doses of fluid product, said reservoir (20), comprising a plunger (25) forming a sealed top when inactivated. The invention is characterised in that the device comprises an elastic element (30), such as a spring, co-operating with said reservoir (20) or the plunger (25), and with a cocking member (40), said cocking member(40) being manually mobile relative to said body (10) to compress said spring (30) and being locked relative to said body (10) in at least one locking position wherein said spring (30) is compressed, said device comprising at least a triggering member (50, 51) designed to release said spring (30) to move said at least one plunger (25) relative to said reservoir (20) to discharge a dose of product.

Description

technical field [0001] The present invention relates to a fluid dispensing device, in particular to a fluid dispensing device for a limited number of doses, such as single and double doses. Background technique [0002] Devices of the single-dose or double-dose type are known in the prior art and find some use in pharmaceutical dispensers for the nasal cavity, in which application one dose of product is to be dispensed per nostril. [0003] Document FR-2761281 proposes such a double dose device. To use the device, the user places the dispensing port in the nostril and applies an axial pressure on the active part of the device. This axial pressure should be great enough to overcome the energy concentration device to ensure that each of the two doses is completely dispensed. When the applied axial pressure is relatively high, it is difficult to accurately control the position of the end point of the device including the dispensing mouth in the nostril, and the end of the dis...
