Problems solved by technology

Depending on the force applied by the user, the delivered dose may not be complete
The inconsistency of the dose delivered is problematic as it may have non-negligible consequences when the substance is a drug
Furthermore, in addition to issues with the amount of substance delivered, the force applied by the user can also affect the spray quality—specifically, the size of the particles or droplets, as well as the angle and density of the spray, which means low mass injection

Embodiment Construction

[0025] From figure 1 As can be seen in the figure, a device for delivering liquid, semi-liquid, viscous or gaseous substances comprises a pump 10, for example for the production of nasal sprays for medicines. The pump 10 is designed to be mounted on a reservoir (not shown) and is typically topped with a user-pressable dispenser tip (not shown).

[0026] The pump 10 comprises: a first part 12, called the fixed part; and a second part 14, called the movable part, which can be moved between figure 2 detent positions shown and figure 1 Movement relative to the fixed part 12 between the actuated positions is shown. In this embodiment, the detent position corresponds to the "high" position and the activation position corresponds to the "low" position.

[0027] In this embodiment, the stationary part 12 comprises a pump body 16 with a dip tube 18 , a piston 20 and a guide bush 22 . A dip tube 18 is connected to the sump from which the substance that enters the pump is drawn. Fu...

Abstract

A device (10) for delivering a substance, the device including a first stationary portion (12) and a second movable portion (14) that is movable relative to the first portion (12) between a rest position and an activated position, the device further including an abutment (56,58) for putting the movable portion (14) into abutment relative to the stationary portion (12), which abutment needs to be forced past in order to enable the movable portion (14) to go from its rest position to its activated position, the abutment (56) carried by the movable portion (14) and an abutment (58) carried by the stationary portion (12), at least one of these abutments (58) being mounted on a resilient portion (60) of the stationary portion (12) and / or of the movable portion (14), the resilient portion being deformable between an abutment configuration and a retraction configuration and having a reinforcement (72) for reinforcing the resilient portion (60), namely a part that bears against a zone of the resilient portion (60).

Description

technical field [0001] The invention relates to the technical field of dispensing liquid, semi-liquid, viscous or gaseous substances, in particular in the medical field. A device for dispensing substances may include pumps such as those used for nasal sprays, or other types of dispenser means such as valves for dispensing ophthalmic liquids, valves for inhaling powders equipment, or the equipment actually used to protect the syringe. Background technique [0002] In the example of a device comprising a pump, as described in document FR 2 885 887, the device comprises a pump body and a dispenser head mounted movably on the pump body up to move between a detent position and an actuated position to deliver a predetermined dose of substance. When the user wishes to use the device, the user presses on the dispenser head, causing the dispenser head to move into its actuated position, thereby delivering a dose of substance. [0003] It has been found that the amount of substance...
