A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

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.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

Flossing device according to the present invention comprise a flossing material attachment platform, a handle and a plurality of flossing material attached to the platform. The device is put into the users mouth and chewed thereby compressing the flossing material and producing tooth joint and subgingival penetration. The plurality of flossing material is systematically trimmed to varying lengths creating an interior angle of 90 degrees which automatically positions the flossing material at the optimum angle in relation to the tooth surface. While the device is chewed in the users mouth, the device dislodges bacteria from between teeth, along the side plane of the tooth, as well as the sulcular pocket. In the process this new device also gently stimulates and massages the gum surface promoting blood circulation and the healing properties associated with increased circulation. Because this new device is painless and user friendly, the frequency of use, compared to current flossing devices, is dramatically increased thereby resulting in much healthier and less tender gums.

The present invention recognizes that there exists a long felt need for brush heads and brushes having material application and buffing properties. A first aspect of the present invention is a brush head. A second aspect of the present invention is a brush including a brush head of the present invention. A third aspect of the present invention is a method of making a brush head of the present invention. A fourth aspect of the present invention is a method of making a brush of the present invention. A fifth aspect of the present invention is a method of using a brush head of the present invention. A sixth aspect of the present invention is a method of using a brush of the present invention. An additional aspect is a brush head having an outer zone of bristles and a convex inner zone of bristles.

A beveled broom and step-on dustpan cleaning system including a step-on dustpan having a step-on portion configured to allow a user to collect debris in a receptacle of the dustpan when a force is applied on the step-on portion. The dustpan includes a lip portion which is configured to seal against a floor surface upon a user stepping on the step-on portion to collect debris. A beveled broom having a broom head configured with a beveled or chamfered shape at a functional angle to provide an effective and efficient contact surface to a floor surface to collect debris during use.

A toothbrush apparatus includes a handle with a longitudinal axis and a toothbrush head constructed and arranged to hold multiple bristles. The bristles are formed in a non-circular configuration. The non-circular configuration is on a distal end, or a portion including the distal end, or the entire bristle. A wall defining an elongated bristle body of each bristle tapers from a base end towards a chisel end of the elongated bristle body. The toothbrush head is of an arcuate shape that conforms to a dental arch. The toothbrush apparatus includes one or more bristle carriers for detachably attaching multiple bristles to the toothbrush head. The second end of each of the bristles of predetermined heights defines a first curved trim profile and a perpendicular second curved trim profile. The bristles in the first curved trim profile at a terminal end of the toothbrush head are extended to reach rear teeth.

An applicator for applying a product to hair, especially a hair colouring product, including: at least one first row of teeth extending longitudinally over a distance l.sub.1, from a first application face of the applicator; and a plurality of second rows of teeth, extending longitudinally over a distance l.sub.1, from a second application face of the applicator, which is arranged opposite the first application face, the ratio l.sub.1/l.sub.2 being lower than or equal to 0.75.

A cosmetic brush is provided that is capable of enhancing an ability to retain a liquid cosmetic material and making fine adjustment to the eyelashes easier. The cosmetic brush comprises a core wire part and a bristle group radially attached to the core wire part around an axis of the core wire part continuously in a helical state in an axial direction of the core wire part. The bristle group has bristles each constituted by integrating a basic fiber made up of a plurality of bundled constituent fibers and a wound fiber helically wound around an outer circumferential surface of the basic fiber.

Disclosed is a new fiber which has a triangular cross section, and which may be used as a substitute for animal hair with comparable pickup and other properties. The disclosure also relates to methods for providing same.
