A method of whitening teeth. The method may include delivering a buffer solution from a reservoir of a toothbrush to one or more tooth cleaning elements of the toothbrush; applying a toothpaste containing a peroxide to the tooth cleaning elements, the toothpaste having a first pH; and brushing the teeth with the tooth cleaning elements, thereby mixing the buffer solution and the toothpaste to form, at surfaces of the teeth, a tooth whitening mixture having a second pH that is greater than the first pH.

A cosmetic bottle with replaceable internal components includes a cover, two buttons, two inner connecting members, a brush rod, an inner bottle, a clamping ring, and an outer bottle that are coaxially arranged. A first button is placed in a first inner connecting member. The cover is sleeved on the first inner connecting member. One end of the rod body of the brush rod is provided with a head, and the other end of the rod body is fixedly connected to a brush head. The head of the brush rod is inserted into the first inner connecting member. An upper connecting portion of the inner bottle is detachably connected to the head of the brush rod, and a lower connecting portion of the inner bottle is fixedly connected to the clamping ring. A second inner connecting member is fixed in a lower opening end of the outer bottle.

One aspect of the present disclosure provides a cleaning tool including: a scraper; a container formed to extend from the scraper; and an outlet disposed at one end of the container, wherein a surface of at least one of the scraper and the container includes concave and convex portions, a sidewall of the container is made of a moisture-impermeable material, and the moisture-impermeable material includes a core layer and a skin layer formed on at least one surface of the core layer.

A cleaner includes a main body and a suction head connected to the main body to suck foreign objects into the main body therethrough, the suction head including a housing including a suction port, and a drum module disposed in the housing, and to be rotated to scatter the foreign objects to be sucked through the suction port so that the scattered foreign objects are drawn into the housing through the suction port, and the drum module including a drum body, a first blade coupled to outer circumference of the drum body, a second blade separated from the first blade in a circumferential direction of the drum body and having a mass greater than a mass of the first blade, and a mass compensation member arranged on the outer circumference of the drum body to compensate for a difference in mass between the first blade and the second blade.

The present invention relates to an applicator device for applying a product of the fluid or pasty type to keratin fibres, comprising a central core (1) having an elongate shape which extends along a longitudinal axis XX, at least one row of elongate spikes (2) comprising a first end (20) embedded in the core and a second, free end (21). According to the invention, at least one of the spikes (2) is delimited by a first flat face (200) that is coincident with a longitudinal plane, known as the reference plane P, and by a second flat face (210) that forms an angle of between 10 and 180° with said first flat face, said at least one spike comprising a first region (22) that is embedded in the core (1) and has a substantially constant cross section in the form of a portion of a circle, and a second region (23) having a variable cross section that is situated substantially in the longitudinal continuation of said first region (22).

The present invention relates to a toothbrush comprising a head portion comprising a cleaning formation for cleaning teeth in use. A handle portion is connected to the head portion. The toothbrush comprises a musical wind instrument, the wind instrument comprising a resonant cavity extending within one or both of the head portion and the handle portion, and an air inlet operatively connected to the cavity and configured to induce resonance with the cavity by exhalation from the user in use.

A head for an oral care implement comprises a number of colored filaments of different types. The filaments extend from a mounting surface of the head and are grouped together to define an initial color pattern. At least two types of filament have staggered time-controlled color changing properties, wherein each of said type of filament changes its color within pre-defined time periods, the pre-defined time periods being different from each other so that the initial color pattern changes color characteristics over at least a first pre-defined period of time to a first color pattern and over a subsequent second pre-defined period of time to a second color pattern, the second pattern being different from the first pattern.

A cleaning implement which utilizes a low-power motor coupled to a plurality of angle gears and drive lines for creating a mechanical action adapted to clean hair and fur. The device includes a housing, which may be bifurcated, and a plurality of bristled protrusions positioned in staggered form along elongated shafts connected to drive lines using angle gears.

An oral care implement having a head with a plurality of cleaning elements coupled thereto and extending therefrom. In the exemplified embodiment, the cleaning elements have a plurality of bristle tufts each including a plurality of bristle filaments. In one aspect, the oral care implement may include a first bristle tuft having inner and outer filaments with the outer filaments being taller than the inner filaments and a second bristle tuft having inner and outer filaments with the outer filaments being shorter than the inner filaments. In another aspect, the oral care implement may include a bristle tuft having inner and outer filaments with the inner filaments being either taller or shorter than the outer filaments, and whereby distal ends of the inner and outer filaments are angled relative to an axis of the bristle tuft.
