At least one radially protruding finger which is integrally connected to the coating is arranged on the outside of the coating. A recess is formed in the outer surface of the coating, and the radially inner foot region of the finger is arranged in the recess and is connected to the coating at the bottom of the recess.

A single-use oral delivery device includes a housing unit configured to house a predetermined amount of oral medication, vitamins and or minerals to be applied to an interdental space of a user, and an interdental device configured to be interlocked with the housing unit, wherein the interdental device includes a cap at a top portion for interlocking and sealing with the housing unit, and an applicator tip at a bottom portion for applying oral medication, vitamins or minerals to the interdental space.

A dental cleaning system (2) comprising a holder (12) for dental floss (18), which includes two mutually spaced brackets (19) and dental floss (18) held between the two brackets (19), and an, in particular U-shaped or annular, base body (1) to be slid onto a finger, which includes a recess (4) situated in the longitudinal direction (3) of the base body (1) for accommodating a fingertip. Essentially, the brackets (19) extend transversely to the longitudinal direction (3) of the base body (1). A first grip surface (9) is situated at least on each of the two sides of the base body (1), which is provided for controlling the movement of dental floss (18) in the mouth with the aid of the fingers adjacent to the base body (1). An appropriate base body (1) comprises, at least on each of the two sides of the base body (1), a first grip surface (9), which is provided for controlling the movement of dental cleaning elements, in particular dental floss (18), in the mouth with the aid of the fingers adjacent to the base body (1). An appropriate holder (12) for dental floss (18) comprises a second part (20) of a form-locking and/or force-locked fastening system (14) to be accommodated in a base body

To provide method for manufacturing interdental cleaner configured to suppress leakage of elastomer from space for forming slip resistance portion in mold to outside of space in step of filling elastomer into mold. Method for manufacturing interdental cleaner includes first step of molding base portion having handle portion and shaft portion (40) by filling composite material into first mold, and second step of forming cleaning portion and slip resistance portion by filling elastomer into second mold (200) with the base portion situated in second mold (200). In first step, what is molded has handle portion including base (24), recessed portion (26), and bulge portion (28) bulging from surface of the recessed portion (26). In second step, cleaning portion and slip resistance portion are formed by filling elastomer into second space from portion of base portion distant from bulge portion (28) toward shaft portion (40).

To provide method for manufacturing interdental cleaner for suppressing elastomer from insufficiently filling into space around shaft portion in filling the elastomer into mold. Method for manufacturing interdental cleaner includes first step of molding base portion having handle portion and shaft portion (40) by filling composite material into first mold, and second step of forming cleaning portion, slip resistance portion and coupling portion by filling elastomer into second mold (200) from distal end portion side of shaft portion (40) with base portion situated in second mold (200), second mold (200) having second space for forming cleaning portion, slip resistance portion and coupling portion. What is used as second mold (200) in second step has ratio no less than 40% of a flow path area in second space for elastomer around distal end portion of handle portion to flow path area in second space for elastomer around proximal end portion of shaft portion (40).

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.

A device for cleaning interdental spaces includes a housing that forms a handle. The device also includes a brush holder for holding an interdental brush, and a drive device which is configured to generate rotational and translational movement of the brush holder and/or of an interdental brush held in the brush holder.

A retractable built-in interdental brush includes a built-in interdental brush, a retractable mechanism, and a handle. The built-in interdental brush is connected to the retractable mechanism. By driving the retractable mechanism, the built-in interdental brush can be driven to extend from the handle to clean a gap between teeth. After use, the built-in interdental brush retracts into an accommodation space of the handle through the retractable mechanism, so that the handle can form a compact instrument box, which is very convenient to carry. An end surface of a delivery device of the built-in interdental brush is an inclined surface and is at an angle β to an axial direction of the retractable built-in interdental brush is, where the angle β is less than 90°.

An interdental cleaner has a gripping portion (3) and a cleaning portion (4) formed by an elongate body made from a thermoplastic material. The cleaning portion (4) has a coating made of a self-adhesive, heat-vulcanized rubber material forming peripheral, flexible brush members (6).
