A cosmetic brush fiber includes five substantially parallel outer edges extending along a length of the cosmetic brush fiber; and five substantially parallel inner edges extending along the length of the cosmetic brush fiber, wherein the cosmetic brush fiber defines a star-shaped transverse cross section.

The present invention is directed to a toothbrush (100) that incorporates tapered bristle filaments (141) in combination with tuft holes (142) of a reduced size, such as between 1.3 mm to 1.4 mm in diameter. In another aspect, the invention provides a toothbrush (100) that balances the number of tuft holes (142) and the number (X) of tapered bristle filaments (141) within each tuft hole (142) to achieve a unique ratio that reduces the cost of manufacture of the toothbrush (100) while maintaining a mouth-feel that consumers associate with a quality product. In still another aspect, the present invention provides a toothbrush (100) that incorporates tapered bristle filaments (141) and also achieves a balance between the perimeter of reduced size tuft holes (142) and the spacing between adjacent tuft holes (142) to achieve a unique ratio that reduces the cost of manufacture of the toothbrush (100) while maintaining a mouth-feel that consumers associate with a quality product.

A mold insert has at least one filament cavity and a stack of at least a first and second insert plates, wherein the first plate has a front face that closely abuts a front face of the second insert plate. A portion of the a filament cavity is provided in at least one of the front faces of the first and second insert plates such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert. A venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided. The venting cavity, which is in air-conducting connection with the blind-hole end of the filament cavity, has a depth between 1 μm and 20 μm. A method of manufacturing the mold insert includes providing first and second insert plates, forming a portion of a filament cavity into at least one of the front faces of the insert plates, forming a venting cavity into the front face with the filament cavity, and bringing the front faces of the plates into close abutment to form a filament cavity.

A brush is provided that is configured for removing debris and hairs, and includes at least one body having a pad, a plurality of bristles having a bending configuration extending from the pad, one end of each first bristle being connected to the pad.

An applicator device for applying a fluid or paste product to keratin fibres or to the skin (epidermis), that includes an elongate core which extends along a longitudinal axis X and has a longitudinal cylindrical shape and a plurality of projections distributed across said core, each projection extending from an anchoring end in the core towards a free end and being integral with said core, and each projection having, at the free end, a means for the uptake and retention of a quantity of fluid or paste product.

Provided are multifunctional cases, device and kits for storing, peeling and cutting a miswak twig. Generally, the multifunctional case comprises a case portion and a cap portion each of which may have one or more compartments therein. The case is configured to store one or more miswak twigs therein and to contain an optionally removable clipper for cutting the twigs. The cap portion contains an optionally removable peeler and may further comprise a storage compartment and/or a cluster of bristling picks. The case may also comprise a mechanism to advance and to retract a miswak twig. The kits provided comprise any of the multifunctional cases or devices described herein and one or more miswak twigs stored within the case or device.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irradiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.

A monofilament bristle including: a body portion; a tip portion extending from the body portion and comprising a multi-lobed transverse cross-section, the monofilament bristle extending along a longitudinal axis; co-extruded first and second components, the first component being a first color and forming a first lobe of the multi-lobed transverse cross-section, the second component being a second color, which is different from the first color, and forming a second lobe of the multi-lobed transverse cross-section; and each of the first and second components forming a longitudinal section of the body portion, with an interface between the first and second components extending substantially parallel to the longitudinal axis.

An interdental brush including a spine of twisted wire, bristles projecting from the spine of the twisted wire, a protective tip at the end of the twisted wire above the bristles where the protective tip includes a ductile cover enveloping the end of the twisted wire, molded and attached to the end of the wire and centered around the end of the wire, and where the ductile cover has a plurality of protrusions, is dome shaped at the closed end, and chamfer shaped at the bristle end.

Provided is a combination broom and cleaning fabric adapter apparatus. The apparatus may include a planar plate having a first and a second surface. The plate may be configured to position a cleaning fabric on the first surface. The first surface may include grippers to grip the cleaning fabric onto the first surface. A stick attachment device may be connected to the second surface for attaching a standard broom or mop stick to the plate at a first location on the plate. The stick attachment device may be configured to allow the stick to pivot freely in two-dimensions relative to the plate. A broom brush attachment device may be connected to the second surface adjacent an edge of the plate for attaching a broom brush to the plate.
