Definitions
- Dispensing devices for fluid products are well known. They generally comprise a reservoir, a dispensing member, such as a pump or a valve, and a dispensing head provided with a dispensing orifice.
- the fluid dispensing devices may also be inhalers comprising a plurality of reservoirs each containing an individual dose of powder or liquid, and means for opening and expelling said doses during successive actuations.
- these devices have many parts that come into contact with the fluid during actuation. There is therefore a risk that the product remains glued or hooked to one or more parts of the device before being distributed to the user. This results in a decrease in the dose distributed over the theoretical dose, which can create serious problems, for example for crisis treatments, such as asthma.
- These gluing problems can arise in particular at the level of the tank or tanks, but also at the level of the piston and the pump chamber or the valve and the valve chamber. It is the same in the pushers or dispensing heads.
- the present invention aims to provide a surface treatment method that does not reproduce the aforementioned drawbacks.
- said thin film is a polymeric film comprising silicone.
- said thin film has a thickness of less than 1 micrometer, between 10 and 2000 angstroms.
- said thin film has a thickness of less than 1 micrometer, between 10 and 800 angstroms.
- said thin film has a thickness between 400 and 1000 angstroms.
- the vinyl-terminated or acrylic-terminated siloxanes are chosen from the group consisting of polyalkylsiloxanes with acrylic or vinyl terminations, such as vinyl-terminated or acrylic-terminated polymethylsiloxane, and vinyl-terminated or acrylic-terminated polydimethylsiloxane, such as polydimethylsiloxane-acrylate (PDMS).
- polyalkylsiloxanes with acrylic or vinyl terminations such as vinyl-terminated or acrylic-terminated polymethylsiloxane
- vinyl-terminated or acrylic-terminated polydimethylsiloxane such as polydimethylsiloxane-acrylate (PDMS).
- a potential difference is applied in said solution.
- the electrodes are made of stainless steel.
- the potential difference is generated by a chemical battery.
- said two thin films are deposited on said support surface simultaneously during the same chemical grafting step in a multi-component bath.
- said dispensing device includes a plurality of individual reservoirs each containing a dose of fluid, reservoir opening means, such as a piercing needle, and dose delivery means for dispensing a dose of product. fluid from an individual reservoir open through a dispensing orifice.
- the solvent employed in the process may be protic or aprotic in nature. It is preferable that the primer is soluble in said solvent.
- adheresion primer corresponds to any organic molecule capable, under certain conditions, of chemisorbing on the surface of the solid support by radical reaction such as radical chemical grafting.
- Such molecules comprise at least one functional group capable of reacting with a radical and also a reactive function with respect to another radical after chemisorption.
- These molecules are thus capable of forming a film of polymeric nature after grafting of a first molecule on the surface of the support and then reaction with other molecules present in its environment.
- the vinyl-terminated poly (dimethylsiloxane) (1.0 g, 5 g / L) was poured into a solution of Brij® (0.874 g to 4.37 g / L) in 70 mL of milliQ water and then the suspension. was magnetically stirred to form an emulsion.
