    Abstract: A method for manufacturing a luminescent timepiece component for a portable object includes producing a pre-mixture of a phosphorescent pigment in an amount of 10 to 40% by weight, a fluorescent pigment in an amount of 1 to 4% by weight and a plasticiser in a maximum amount of 10% by weight; mixing a polymer base with the pre-mixture and extruding a first time the mixture obtained to obtain a homogeneous polymer mixture; extruding a second time the polymer mixture to form a strip of a predetermined thickness; and cutting the strip to obtain the desired luminescent timepiece component.

    CPC classification number: A44C5/0007

    Abstract: The invention relates to a bracelet strand made of a transparent or translucent elastomer material, comprising a first end capable of connecting to a watch case, characterised in that it comprises a rigid insert having a solid part forming a reinforcement, and a hollow part arranged to receive a fluid and solid elements dispersed in the fluid, said hollow part being located at the centre of the solid part, and in that the insert is coated in the transparent elastomer, and is positioned at the first end capable of connecting to a watch case.

    Abstract: A fashion item (100) including a thin wall with locally and selectively expandable areas including: an internal core (30) made of a lining material which can expand in contact with a liquid; a support layer (10) having an external face (11) opposite an internal face (12) on which the internal core (30) is arranged, the support layer (10) being configured so that the expansion of the lining material does not substantially cause its deformation; and an impermeable covering layer (20) attached to the support layer (10) so as to tightly enclose the internal core (30), the layer including one or a plurality of through holes (21) opening onto the internal core (30) and arranged relative to each other so as to form a predefined matrix, the covering layer (20) being configured such that the expansion of the lining material substantially causes its deformation.

    Abstract: A method for core impregnation of a finished part made of plastic material with an additive, including: dissolving the additive in a liquid medium to form a solution; placing the plastic part at ambient pressure in a pressure enclosure; hermetically sealing the chamber; impregnating the plastic part with the solution by a fluid at supercritical or near supercritical conditions in the enclosure at a pressure between 3 MPa and 6 MPa, at a temperature between 25° C. and 65° C. for a duration between 1 minute and 15 minutes; releasing the pressure inside the enclosure so that the liquid medium diffuses outside the plastic part and to trap the additive inside the plastic part.
