Abstract: An instrument (1) for applying a product to superficial epidermal derivatives comprising an elongated core (4) and at least one nucleus (5) supporting an applicator (6) of the product. The core (4), which is twisted, passes through the nucleus (5), and the core (4) and nucleus (5) are connected to prevent the nucleus (5) from pivoting freely on the core (4).

Abstract: An instrument for applying a composition to hair or nails includes a core made as a single piece that extends longitudinally along a mean longitudinal axis. The instrument includes a plurality of applicator projections for applying the composition to hair or nails. The applicator projections are carried by the core and are spread out helically along the core. The helical spreading of the projections is obtained by twisting the core. The projections are disposed on the core, prior to twisting the core, along at least three distinct radial directions about the mean longitudinal axis. The instrument further includes a twister element to which the core is attached such that the twisted nature of the core is imparted by the twister element.

Abstract: An instrument (1) for applying a product such as mascara to epidermal derivatives, comprising an application means (4) for applying the product to the epidermal derivatives, wherein the instrument comprises a twisted plate (5) bearing the application means (4).

Abstract: A cosmetic fluid dispensing apparatus (1) comprising a bottle (2) for containing the cosmetic fluid to be dispensed, the bottle (2) being deformable when compressed from a rest configuration in which the bottle (2) has a predetermined capacity to at least one deformed configuration in which the bottle (2) has a smaller capacity than the predetermined capacity, the bottle (2) having a shape memory in order to revert to its rest configuration, the bottle (2) being disposed between two flaps (3, 4) separate from the bottle (2), the flaps (3, 4) are brought together by a closing force in order to give the bottle its deformed configuration, and the assembly formed by the flaps (3, 4) having a shape memory so as to revert to a configuration in which the compression by the flaps (3, 4) is removed.

Abstract: An instrument for applying a composition to hair or nails includes a core made as a single piece that extends longitudinally along a mean longitudinal axis, and includes a plurality of applicator projections for applying said composition to hair or nails, said applicator projections being carried by the core and being spread out helically along said core, said helical spreading of the projections being obtained by twisting the core, said projections being disposed on the core, prior to twisting said core, along at least three distinct radial directions about said mean longitudinal axis, said instrument further including twister means to which said core is attached such that the twisted nature of the core is imparted by said twister means. The invention also relates to applicator instruments.
