Definitions
- the present invention relates to a dispenser for a liquid product containing a film-forming polymer. More particularly, this dispenser is an aerosol dispenser comprising, in a container, a pressurized propellant, a dispensing nozzle and a dispensing valve for controlling, at will, the dispensing of the product, and making it possible to deliver this product in the form of fine droplets. or fog.
- the product to be sprayed is an aqueous or hydroalcoholic composition containing at least one film-forming polymer. More particularly, this composition is a hair composition such as a hairspray for fixing the hair, a lotion for brushing, a styling lotion or a styling composition.
- the hair compositions to be sprayed onto the hair essentially consist of an alcoholic or hydroalcoholic solution and a solubilized polymer, optionally mixed with various cosmetic adjuvants.
- this solution is packaged either in a pump bottle or in a suitable pressurized container.
- Document EP-A-0 008 109 discloses a pressure distributor for dispensing a liquid product or a dispersion of particles.
- This dispenser is provided with a valve comprising a main body and a premix chamber provided with an additional gas outlet.
- the product is brought into this chamber by a capillary dip tube.
- the chamber is in communication with the valve body.
- the valve body can be placed in communication with a spray nozzle by actuation of an operating rod which has, for this purpose a passage orifice, closed in the rest position.
- the flow rate of the valve is determined by the section of the capillary tube. According to this document, by using a valve with a premix chamber, the flammability of the product to be sprayed is reduced.
- a dispenser with a sequential valve comprising an additional gas intake and provided with a mixing prechamber.
- This valve is configured so as to allow the purging of the distribution conduits downstream of the valve by a jet of pure propellant gas.
- the valve is provided with a prechamber into which an additional gas intake ends.
- propellant gas enters the prechamber, which has the consequence that the internal pressure in the prechamber drops, so that any aspiration of the product by a suction passage is prevented.
- valve stem When the valve stem is fully inserted, said passage is closed off by a projection of the stem, so that a gas / product mixture can be dispensed.
- the volume of the prechamber is occupied substantially entirely by the lower portion of the rod, so that, in the dispensing position, this prechamber is substantially nonexistent. In other words, in the dispensing position, this valve has substantially no prechamber.
- document BE-A-664,905 describes a valve of the same kind. At the bottom of the valve body is provided a product inlet orifice, ending in a premix chamber provided with an additional gas intake. Bedroom premix is separated from the main valve chamber by an elastomeric wall which is traversed by a through hole. Upon actuation of this valve, the elastomeric wall is pushed towards the bottom of the valve body, so that the premix chamber becomes substantially nonexistent.
- the problems posed by such a device are identical to those described with reference to document US-A-3,653,553.
- the correct spraying being an essential element for the final quality of the application of a hair composition to be sprayed onto the hair, it is essential to remedy these drawbacks in order to obtain a good quality of fine particles and a good distribution of the spray over the of the whole hair.
