Abstract: A piston for a reservoir of a dispenser of a fluid product without air intake, and presenting a central axis X includes both sealing means and also guiding means. The sealing means extend in a plane orthogonal to the axis X and define a single external sealing line in a closed loop, distal from the axis X, capable of coming into contact with an inner wall of the reservoir 10. The guiding means include a base from which extends one or more tabs with free ends defining external guide points, distal from the axis X, capable of coming into contact with the inner wall of the reservoir.

Abstract: The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

Abstract: A device for diffusion of a liquid product, of the perfume type, stored in a reservoir includes at least one fixed part capable of being mounted on the reservoir, and offering at least one point of product supply by capillarity, the fixed part including a fixed porous body capable of being impregnated with product by capillarity by being directly immersed in the reservoir. The device also includes a nomadic element for each supply point, including a mobile porous body capable of being impregnated with product by capillarity while being in contact with the fixed porous body when the nomadic element is mounted on the fixed part. The nomadic element also includes a decorative structure of the jewel type, the mobile porous body being housed inside the decorative structure.
