#CMT# #/CMT# The element e.g. return spring (6), has a coating surface that is a coating barrier to avoid contact between the element and a fluid product such as perfume, where the element is made up of polymer or metal material. The coating surface is made up of inert polymer material such as Parylene(RTM: Polyparaxylene), and is highly resistant to the fluid product, and cosmetic and pharmaceutics products. #CMT# : #/CMT# An independent claim is also included for a method for coating a surface of a constituent element. #CMT#USE : #/CMT# Metal constituent element e.g. return spring, for a fluid product e.g. perfume, distribution unit (claimed) such as pump or valve, that is used for a fluid product distributor in a cosmetic field. #CMT#ADVANTAGE : #/CMT# The element of the fluid distribution unit avoids the distribution of superficial harmful materials that can interact with the product. The element ensures that the coating surface has high resistant to the products. The element can be manufactured in simple and reliable manner. The design of the element maintains the physio-chemical property e.g. thermal impact, mechanical property e.g. sensitivity of element structure, and aesthetic property such as taste and aroma, of the fluid distributor to be more compatible with usage of the element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical transverse sectional view of a fluid product distribution unit. 1 : Fluid distribution unit's body 2 : Actuating rod 3 : Piston 4 : Shell 6 : Return spring. |
