The toothbrush includes a handle and a head, the handle forming two bodies (1) and (2) provided with overlapping sectors (3), which permit the axial displacement, one with respect to the other, the body (1) constituting a container (4) for the toothpaste, which can be projected toward the exit (14) through a duct (7-8), in which are defined two sectors, one rigid (7) and the other flexible (8), the latter of the bellows type, sector (7) ending in a one-way valve (12-13), which tends permanently toward the closed position and which, while permitting the passage of the toothpaste toward the exit (14), blocks the return of the toothpaste in the backward direction axially of the body (1). An embolus (15) fills up the inside of the body (1), compensating for the dose of toothpaste which is supplied, while in the exit (14) a manually operated valve (17) is incorporated in the cylinder provided in an diametral orifice (18), which can be made to align with or not align with the exit orifice (14). The head (26) of the toothbrush is coupled to a tubular core (27), in which the extreme anterior of the body (2) of the handle ends, which head (26) being capable of movement with relation to the tubular core (27) in such a way that, when it is displaced outward, between a gasket (29) and the mouth (30) of the tubular core (27), a chamber (31) is defined, which communicates with the outside through an exit orifice (32), which orifice closes behind the dose of toothpaste by means of a new axial retraction of the head (26) on the tubular core.

A makeup device includes a cylindrical body which can accommodate a sealed reservoir containing a viscous or pasty makeup product, especially a mascara, and is capable of dispensing a measured amount of the product contained in the reservoir through a nozzle in the front opening of the reservoir onto an applicator. The applicator is permanently mounted on the cylindrical body in the vicinity of the front end of the body and includes a shaft. At the end of the shaft is mounted an applying element, the shaft being provided with an internal passage terminating by at least one orifice at its periphery, and contacting with the nozzle in the front opening of the reservoir. The device also includes a cap capable of enclosing the applicator and capable of separably attaching to the body in the vicinity of the front end of the body.

A toothbrush with a toothpaste feed system that includes a toothpaste cartridge feed handle, a hollow brush head, a resilient hinge openable neck structure connected between the toothpaste cartridge feed handle and the hollow brush head and providing a neck toothpaste passageway between a toothpaste feed end of a toothpaste cartridge cavity within toothpaste cartridge feed handle and a brush head toothpaste passageway formed within hollow brush head, and an accordion fold toothpaste filled cartridge with a rupturable perforated foil end that is sized to fit into the toothpaste cartridge cavity with the rupturable perforated foil end positioned within toothpaste feed end of toothpaste cartridge cavity. The back of the hollow brush head is provided with a flip open back cap that is in connection with the brush head toothpaste passageway and which is moveable into an open position to allow for cleaning of the brush head toothpaste passageway between uses.

An applicator tip for applying a composition to a tooth surface includes a structural body having a closed distal end portion and an inlet formed opposite the closed distal end portion. Preferably, but not necessarily, a plurality of fibers coat at least a portion of the closed distal end portion of the applicator tip. The applicator tip includes an axial opening formed within the structural body proximal to the closed distal end portion such that the structural body forms a channel that provides fluidic communication between the inlet and the axial opening.

A delivery tip for use on a delivery device for applying a dental composition to tooth surfaces includes a tubular member having a proximal end and a distal end. The proximal end of the tubular member is coupled to the delivery device. A plurality of fibrous bristles are disposed on an outer periphery at the distal end of the tubular member. The fibrous bristles can be used in an agitating action to remove entrapped air bubbles from the applied composition such as an impression material. The fibrous bristles on the delivery tip can also be used to coat and spread the composition on tooth surfaces. With the fibrous bristles attached to the outer periphery at the distal end of the delivery tip, the composition can be delivered through the passageway in the tubular member without interference from the bristles.
