A toothbrush that can more effectively clean an interdental gap, a gap between a tooth and gums, a dental groove, and a surface of the tooth and the gums.

In the toothbrush, a bristle implanting section is formed so that a bristle implanting surface is in an elliptical shape of which the major axis direction corresponds to the longitudinal direction of a handle when viewed from the tip part side of bristle bundles. The brush section includes a plurality of center bristle bundles arranged along the major axis direction at the center of the ellipse in the minor axis direction and a plurality of side bristle bundles arranged on both sides of the plurality of center bristle bundles in the minor axis direction. At least, the center bristle bundles are formed to be gradually inclined upwardly from both sides to the center of the ellipse in the major axis direction.

A shed hair collection device includes a substantially planar mat and a gel pad. The mat has multiple substantially cylindrical protuberances with multiple nubs extending therefrom. A gel pad has multiple apertures attached to the mat such that each of the protuberances extends through one of the apertures. A shed hair collection device includes a hairbrush and a gel screen removably attached thereto. The hairbrush has a head with bristles and a handle. The gel screen has multiple apertures encircling the bristles. A shed hair collection device includes a silicone gel pad with multiple apertures and at least one loop formed at the perimeter. The silicone gel pad installs on a hairbrush head with bristles extending through the apertures.

A powered toothbrush and toothbrush head comprise a transmission housing; a substantially disk-shaped bristle carrier; a plurality of first bristle tufts arranged on the bristle carrier along a first virtual circle; and a plurality of second bristle tufts arranged on the bristle carrier along a second virtual circle, the second virtual circle being concentric with and having a smaller diameter than the first virtual circle, wherein each of the plurality of first bristle tufts includes a plurality of bristles of a first type, having a tapered form.

The brush for the application of cosmetic products comprises an housing seat for housing at least an application body having a plurality of spreading elements to spread a cosmetic product on a user, in which the housing seat comprises at least a concave portion and defining on the application body at least an application face of the cosmetic product.

A mechanically tapered bristle filament for an oral care implement. The filament is characterized by a long thin tapered end portion. The tapered end portion has a taper length and tip diameter comparable to chemically tapered filaments. The areal surface roughness of the tapered end portion however is greater than chemically tapered filaments thereby producing increased scrubbing action against the surfaces of the teeth. The foregoing taper and roughness characteristics of the present filament enhance inter-dental cleaning effectiveness.

A dental appliance for removing material from the mouth of a user is disclosed. The appliance has a body with a plurality of bores extending through the body. A cleaning element is positioned in each of the bores. The cleaning elements are disposed to extend beyond the body and are moveably positioned in the bores.

An automatic suction cleaning structure is disclosed. The automatic suction cleaning structure is disposed on a cleaner body. The automatic suction cleaning structure comprises a fixing base (1) connected to the cleaner body and a number of brush heads (2) arranged on the fixing base (1). The brush heads (2) are made of silica gel, and are of a hexagon shape and a hollow structure. The number of brush heads (2) are arranged on the fixing base (1) in an array and distributed in a cellular arrangement. By arranging the cellular brush heads (2) of a hollow structure and utilizing a suction force produced by the tightly-attached brush heads (2) during use, dirt on the skin surface is sucked automatically by means of a sucking disc principle in a process of contact with the skin, to allow more thorough cleaning. A cleaner is also provided.

A method for cleaning a coke deposit from an internal surface of a process equipment, comprising removing at least a portion of the coke deposit from the internal surface using a flexible pig comprising a plurality of bristles, without damaging a metal protective layer of the internal surface of the process equipment. A flexible pig for cleaning a coke deposit from an internal surface of a process equipment without damaging a metal protective layer of the internal surface, comprising a flexible body formed of a polymeric material, and a plurality of bristles partially encapsulated by the polymeric material of the flexible body.

A powered toothbrush and toothbrush head comprise a transmission housing; a substantially disk-shaped bristle carrier; a plurality of first bristle tufts arranged on the bristle carrier along a first virtual circle; and a plurality of second bristle tufts arranged on the bristle carrier along a second virtual circle, the second virtual circle being concentric with and having a smaller diameter than the first virtual circle, wherein each of the plurality of first bristle tufts includes a plurality of bristles of a first type, having a tapered form.

[Problem] This invention provides a makeup brush that not only enables easy application of cosmetics such as blushers and eyeshadows while creating gradations, but also achieves a beautiful finish, without requiring special makeup techniques. [Solution] A makeup brush 1, wherein an upper opening portion 2a of a cylindrical member 2 is formed into an arc shape having a predetermined width when planarly viewed, and a tip surface 3a of a brush 3 that is formed by tips of bristles extending upward from the upper opening portion of the cylindrical member is a composite curved surface having a first protruding curved surface 6 that is formed in such a manner that a length of brush bristles becomes gradually longer from an inner curved surface 4 having the arc shape toward an outer curved surface 5 having the arc shape, and a second protruding curved surface 7 that is formed in such a manner that the length of the brush bristles gradually changes along a length direction of the arc shape and that the brush bristles are the longest at approximately a central portion.
