This disclosure relates to oral care appliances and methods of forming oral care appliances. A disclosed oral care mouthpiece includes a flexible membrane and a set of oral care elements attached to the flexible membrane. The set of oral care elements have a composition with a hardness of at least 50 Shore Type A (shA). Each oral care elements in the set of oral care elements has a minimum stiffness value higher than 410.sup.8 newton meters and lower than 610.sup.3 newton meters. The stiffness value and hardness of the oral care elements are both critical values for the disclosed appliances and methods. The stiffness value can be expressed as the product of the Young modulus of the oral care element and the moment of inertia of the oral care element divided by the length of the oral care element.

Example aspects of a cosmetics brush and a method for using a cosmetics brush are disclosed. The cosmetics brush can comprise a brush body; a brush head coupled to the brush body, the brush head defining a substantially disc-shaped cross section, a hole defined through a center of the brush head; a core received within the hole, the core defining a receiver surface configured to receive cosmetics thereon; and a mesh layer extending across the hole and configured to cover the receiver surface.

An apparatus for applying cosmetic solutions includes: a holder, including a cap, a stem, and a brush; and a bottle configured to hold a solution, wherein the brush is disposed at a first end of the stem and a second end of the stem is attached to the cap; the stem includes an absorbing structure configured to absorb the solution; and the brush is configured to wick the solution from the absorbing structure of the stem.

An interdental brush device comprising an interdental brush including a working part and a connector; a delivery component including a guide head, a sliding mechanism including a sliding block and an interdental brush connecting mechanism, and a housing; the interdental brush comprises a working part with fiber or a protrusion and a connector; the interdental brush is positioned within a bended tube, and the connector of the interdental brush is detachably coupled to the interdental brush connecting mechanism such that lateral movement of the sliding mechanism drives the working part of the interdental brush to slide within the bended tube, the protrusion is made of elastic polymer material, and the connector and the protrusion are formed into a whole; and the sliding mechanism is configured to make the working part of the interdental brush extend from the outlet of the bended tube at the end of the guide head.

The invention relates to dental micro-applicators having a body with a distal and a proximal end, whereby, on the proximal end, an application aid is provided, at least in part, with at least one additive selected from metals, metal-containing compounds, and organometallic compounds for affecting the polymerisation of dental materials, as well as a method for the production thereof and a kit comprising the applicator and a dental adhesive.

In one aspect, the present disclosure provides a brush for applying a formulation, the brush having a core having an outer surface and a longitudinal axis, a plurality of bristle rings protruding from the core and spaced apart along the longitudinal axis, each bristle ring having at least 6 bristles spaced radially apart around the outer surface of the core, and a high density zone that covers at least a portion of the outer surface of the core, the high density zone having an equivalent 360 degree linear bristle density of 13 to 31 whole bristles per 0.5 mm of length along the outer surface of the core measured along the longitudinal axis, and a surface bristle density of 3 to 5 bristles per square millimeter of area of the outer surface of the core.

A valve housing adapter for a paint pen kit includes a protruding inlet, a protruding outlet and a valve. The protruding inlet is adapted to matingly fit a syringe housing and the protruding outlet is adapted to matingly fit a paint tube housing. The valve having a closed position configured to bias a plug so as to prevent fluid flow through a dispensing tip of the syringe housing in the closed position when the protruding inlet is matingly fitted to the syringe housing. The valve is further configured to flex to an open position whereby the plug is no longer restrained relative to the dispensing tip of the syringe housing.

A leg-driven cleaning system embodying cleaning footwear device fluidly connected to cleaning solution is provided. The cleaning footwear includes cleaning bristles along an underside thereof, as well as a nozzle adjacent to the underside for selectively applying the cleaning solution while a wearer of the cleaning footwear device utilizes their leg strength to wipe their feet to scrub their carpet clean. The leg-driven cleaning system does not take up much room, is easy to store, is very cost effective, and anyone from the ages seven to ninety can operate.

A lighting-enabled interdental brush of the present application includes an interdental brush and a delivery component, where a guide head, a housing, and a lighting system are disposed on the delivery component, the interdental brush is installed on the guide head, and the lighting system can provide lighting for the interdental brush; therefore, a lighting condition in an oral cavity is significantly improved, the clearance between molars may be clearly observed, and a process that the interdental brush enters the tooth clearance is directly observed, which is convenient for cleaning and avoids an accidental injury to gum. An observation system is further designed on the interdental brush of the present application, by using the observation mirror or camera system during use, a process that the interdental brush enters a tooth clearance is observed directly, which is convenient for cleaning and avoids an accidental injury to the gum.

A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.
