A method for manufacturing an interdental cleaner includes providing a rod-shaped carrier made of plastic, into which laterally protruding bristles are embedded. In this case, a filament array formed of a plurality of filament strands is inserted into a holding cassette and is fixed in a predefined alignment in the holding cassette by means of a holding device. The holding cassette is then inserted into an injection-molding device and the filament array is extrusion-coated with plastic in the injection-molding device, forming a plurality of rod-shaped carriers arranged spaced apart next to one another. Finally, the filament strands forming the filament array are separated at least in the sections located between adjacent rod-shaped carriers. In addition, a device for carrying out the method is provided.

The present invention relates to an applicator (2) for applying a cosmetic, makeup or care product (P) to the eyelashes and/or eyebrows, having a moulded applicator member (8) having:—a core (10) that extends along a longitudinal axis (X) and has two opposite longitudinal grooves that turn around said longitudinal axis (X) as they extend along the latter, and—spikes (18) carried by the core (10).

An oral implement and a method of forming an oral care implement. The oral care implement may include a head having a front surface and a plurality of tooth cleaning elements extending from the front surface. In one embodiment, the plurality of tooth cleaning elements may include three different types of tooth cleaning elements, each type of tooth cleaning element being formed of a different material. In one embodiment each of the materials has a different hardness and thus the oral care implement includes three different types of tooth cleaning elements each having a different hardness. In another embodiment, the oral care implement may include bristles and a molded cleaning element that may function as an interdental cleaner. Such a molded cleaning element may include a body and tines extending therefrom.

To provide method for manufacturing interdental cleaner configured to suppress leakage of elastomer from space for forming slip resistance portion in mold to outside of space in step of filling elastomer into mold. Method for manufacturing interdental cleaner includes first step of molding base portion having handle portion and shaft portion (40) by filling composite material into first mold, and second step of forming cleaning portion and slip resistance portion by filling elastomer into second mold (200) with the base portion situated in second mold (200). In first step, what is molded has handle portion including base (24), recessed portion (26), and bulge portion (28) bulging from surface of the recessed portion (26). In second step, cleaning portion and slip resistance portion are formed by filling elastomer into second space from portion of base portion distant from bulge portion (28) toward shaft portion (40).

To provide method for manufacturing interdental cleaner for suppressing elastomer from insufficiently filling into space around shaft portion in filling the elastomer into mold. Method for manufacturing interdental cleaner includes first step of molding base portion having handle portion and shaft portion (40) by filling composite material into first mold, and second step of forming cleaning portion, slip resistance portion and coupling portion by filling elastomer into second mold (200) from distal end portion side of shaft portion (40) with base portion situated in second mold (200), second mold (200) having second space for forming cleaning portion, slip resistance portion and coupling portion. What is used as second mold (200) in second step has ratio no less than 40% of a flow path area in second space for elastomer around distal end portion of handle portion to flow path area in second space for elastomer around proximal end portion of shaft portion (40).
