Abstract: A cosmetic product applicator including a straight stick extending according to a main axis with a longitudinal direction, the stick including an external surface over which furrows are formed. Over at least one longitudinal portion of the stick, the external surface of the stick includes at least two helical furrows, one of the two furrows having a right-hand pitch and the other one having a left-hand pitch, the furrows meeting several times over the longitudinal portion of the stick, such an applicator having furrows with opposite pitches improving combing and separating of the eyelashes (or other hairs) when applying a cosmetic product. The presence of furrows having opposite pitches allows for an efficient use of the applicator both with the right hand and with the left hand, with an identical or similar make-up quality. The applicator is well-suited to be used in a “mascara pen” type mascara item.

Abstract: A pot for a cosmetic product including a base topped by a substantially cylindrical neck defining an opening, and a lid equipped with a seal having top and bottom surfaces. The neck of the pot has a rim with an inner periphery having a shoulder forming a concave surface. The bottom surface of the seal includes a flexible annular lip that has a convex shape on an outer peripheral wall which, when the lid is tightened on the base, matches the concave surface over at least a portion of the height of the shoulder and presses sealingly against the rim around the entire inner periphery of same to sealingly close the pot. The flexibility of the seal and the shape of the lip thereof, which complements that of the rim, allow it to be deformed to be able to compensate for dimensional irregularities during at manufacture ensuring tight sealing.

The fixed portion is hollow, so that it includes an elongated cavity, and it includes holes connecting the cavity and an exterior area. The applicator includes a movable portion in relation to the fixed portion, the movable portion including an elongated central core in the longitudinal direction and disposed in the cavity formed by the fixed portion. The movable portion includes protuberances, each protuberance passing through a hole of the fixed portion so that it protrudes outside of said fixed portion. The configuration of the protuberances and of the holes makes it possible to move at least longitudinally the movable portion in relation to the fixed portion. The applicator may be obtained by additive manufacturing.

Abstract: Applicator for cosmetic product having an elongate general shape in a longitudinal direction, including a fixed part and a part movable in relation thereto. The movable part includes protrusions, at least one chain having a strand forming a succession of open loops, the chain extending substantially parallel to the longitudinal axis of the applicator. The fixed part includes at least two links, at least two of the open loops on each chain being passed through by a link of the fixed part. Thus, each chain of the movable part is fastened with at least one degree of freedom to the fixed part, enabling relative movement of the chain in relation to the fixed part longitudinally. This improves quality of the application of the product and gives the applicator a sensation of flexibility, even if the applicator is constituted by a rigid material. The applicator can be made by additive manufacturing.
