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.

An oxidant production apparatus comprises an electrochemical reactant reservoir, an electrolysis compartment, a porous first electrode and a second electrode. The porous first electrode defines a boundary between the reservoir and the electrolysis compartment and is configured to allow an electrochemical reactant to pass from the reservoir, through the first electrode and into the electrolysis compartment. The second electrode disposed at least substantially in the electrolysis compartment and spaced apart from the first electrode. The apparatus is configured to produce an oxidant in an electrochemical reaction when a voltage is applied across the first and second electrodes and a current is passed through the first and second electrodes and an electrolyte disposed in the electrolysis compartment.

Example aspects of a cosmetics brush head, a cosmetics brush, and a method for using a cosmetics brush are disclosed. In a particular example aspect, the cosmetics brush head can comprise a cosmetics applicator; and an applicator tube nested within the cosmetics applicator, the applicator tube defining a tube cavity configured to receive cosmetics therein.

Example aspects of a cosmetics brush head, a cosmetics brush, and a method for using a cosmetics brush are disclosed. In a particular example aspect, the cosmetics brush head can comprise a cosmetics applicator defining an application end; and an applicator arm nested within the cosmetics applicator, the applicator arm defining a cosmetics surface configured to receive cosmetics thereon, the cosmetics surface defining a concave cosmetics surface.

The present disclosure provides a system including a handheld implement having a handle and a head. The system also includes a base having a basin, a pump, and a product container. The basin includes vertical walls forming mouth opening to an inner cavity that receives the head of the handheld implement. The product container includes a reservoir of product. The pump conveys the product from the reservoir to the inner cavity via at least one through-hole in the basin.

A liquid supply apparatus having an internal reservoir. In one embodiment, the invention can be a liquid supply apparatus including a housing having an internal reservoir containing a fluid. A partition member may be positioned within the internal reservoir to divide the internal reservoir into a first chamber and a second chamber. The partition member may include a passageway extending therethrough and terminating as a first opening in a first surface of the partition member and as a second opening in a second surface of the partition member. A capillary member is located within the second chamber and extends from a first end to a second end. The partition member prohibits axial movement of the capillary member into the first chamber.

A personal care implement that dispenses a fluid to cleaning elements during a hygiene activity. The personal care implement may include a handle, a head, and a reservoir containing a fluid in one of the handle and the head. A plurality of bristle tufts may extend from the head along an axis. Each of the bristle tufts may include a plurality of bristle filaments that are arranged in the bristle tuft so that spaces exist within the bristle tuft. The personal care implement may also include a capillary member that is fluidly coupled to both the first fluid and to one of the bristle tufts. The fluid may flow by capillary action from the reservoir to a bottom end of the one of the bristle tufts and then upwardly along the bristle tuft within the spaces between the bristle filaments.

A single dose package having a material chamber frangibly separable from a handle and concentric partial or semi-cylinders holding an applicator. An outer partial cylinder placed over an inner semi-cylinder encloses and holds an applicator. Moving the handle relative to the material chamber separates the handle from the material chamber to access a material contained within the material chamber. Different sizes and shaped plugs selectively adjust the volume of the material chamber.

A laundry treating appliance includes a chassis defining an interior. A rotatable treating chamber is located within the interior. The laundry treating appliance further includes a dispenser having at least one treating chemistry reservoir fluidly coupled to the treating chamber and at least one tool docking station fluidly coupled to the treating chamber. A treating tool has an internal treating chemistry reservoir and is configured to dock with the tool docking station to fluidly couple the internal treating chemistry reservoir with the treating chamber.

A spreading device comprises a container comprising a dispensing end and an exterior surface, and at least one gripping or handling surface extending from the container for gripping or handling the spreading device, squeezing or applying pressure against the exterior surface of the flexible container, and causing the dispensing of a spreadable substance out of the dispensing end of the container.
