An oral care implement having a collapsible elastomeric element. The oral care implement may include a body having a handle portion and a head portion. Furthermore, an elastomeric element may extend from the body. The elastomeric element may comprise a hollow body that has an internal cavity, the hollow body having a base section, a middle section, and a distal section that includes a free distal tip, each of the base, middle, and distal sections coupled together by a pre-weakened section. The elastomeric element may be configured to alternate between a collapsed state and a normal state.

An oral hygiene handle device is configured for a holding of an oral-hygiene means, in particular an interdental brush, with at least one base body comprising at least one accommodation region for an accommodation of the oral-hygiene means in an application position wherein the accommodation region of the base body is longer than 30 mm, and is configured for an accommodation of a handle element of the oral-hygiene means.

A brush (200) for cleaning a periodontal pocket between a tooth and a gum of a user. The brush (200) comprises: a handle portion (205); an arm extending (210) from the handle portion; and a brush head (211) located at an end of the arm having a plurality of brush filaments (212) extending therefrom. The brush filaments (212) are configured to be inserted into a periodontal pocket. The brush (200) can be used to assist in the treatment of gum disease by enabling a user to precisely clean periodontal pockets. The brush (200) may be for self-use. Alternatively, the brush (200) may be used by a healthcare professional such as a dentist or hygienist to treat a patient or to demonstrate its use.

An interdental brush including a spine of twisted wire, bristles projecting from the spine of the twisted wire, a protective tip at the end of the twisted wire above the bristles where the protective tip includes a ductile cover enveloping the end of the twisted wire, molded and attached to the end of the wire and centered around the end of the wire, and where the ductile cover has a plurality of protrusions, is dome shaped at the closed end, and chamfer shaped at the bristle end.

An electrical appliance for personal care includes a handle with a longitudinal axis, and a plug-on part which can be attached to the handle, wherein a vibration unit having an electric motor and an eccentric element is arranged in the handle, wherein a plug-like coupling structure protrudes from the handle, which plug-like coupling structure forms an interface with a substantially mirror-inverted socket-like coupling structure of the plug-on part, wherein the interface has at least two stages with different circumferential geometry, wherein at least one of the stages has a rotation-preventing device between the handle and the plug-on part, and wherein a stop surface of the handle for the plug-on part extends obliquely with respect to the longitudinal axis of the handle.

A portable interdental toothbrush according to the present invention can be carried conveniently since a cleaning solution tube stays in a sealed state when carried without using it, which makes it convenient to use. When using, an engaging protrusion fixed to an engaging portion is released to wet a brush with the cleaning solution filled in the cleaning solution tube through the discharge hole by pulling the brush body to use the interdental toothbrush, thereby the structure is simple, the production is easy, and production cost is low, thereby allowing any user to use it, which promotes the dental and oral health for citizens.

An interdental cleaner has a rod-shaped carrier consisting of plastic, which has a cleaning device in an axial end area. The cleaning device comprises at least one fabric part, which extends in the direction of a longitudinal axis of the carrier and which has mutually intersecting thread systems with warp threads and weft threads. Provisions are made for the fabric part to be connected to the carrier and to radially project from same, wherein thread systems or the warp threads, on the one hand, and the weft threads, on the other hand, extend at an angle in the range of 20° to 70° to the longitudinal axis of the rod-shaped carrier and pass through the rod-shaped carrier.

A method for manufacturing an interdental cleaner includes providing a rod-shaped carrier made of plastic, into which laterally protruding bristles are embedded. In this case, a filament array formed of a plurality of filament strands is inserted into a holding cassette and is fixed in a predefined alignment in the holding cassette by means of a holding device. The holding cassette is then inserted into an injection-molding device and the filament array is extrusion-coated with plastic in the injection-molding device, forming a plurality of rod-shaped carriers arranged spaced apart next to one another. Finally, the filament strands forming the filament array are separated at least in the sections located between adjacent rod-shaped carriers. In addition, a device for carrying out the method is provided.

An interdental cleaning device (1) for being inserted into an interdental space to clean the interdental space includes a rod-shaped core portion (12); and a soft portion (20) being softer than the core portion (12) and covering the outer surface of at least a part of the core portion (12) including a core front end (P1) as the front end of the core portion (12), wherein the soft portion (20) has a partial length of 0.5 mm or more between the core front end (P1) and a soft front end (P2) as the front end of the soft portion (20).

Provided is a method for manufacturing an interdental cleaning device (1) including a base portion (10) having a handle portion (11) and a core portion (12); and a soft portion (20) having a cleaning soft portion (21), a non-slip portion (22), and connecting portions (23) extending from two sites of the non-slip portion (22) and being connected to the cleaning soft portion (21). The method includes causing a second gate (49) of second molds (40) and (41) for molding the soft portion (20) to open at a position substantially equally distant from positions of two communicating openings (48a) of a non-slip molding space (47) for molding the non-slip portion (22), the two communicating openings (48a) communicating with connecting portion molding spaces (48) for molding the connecting portions (23); and charging the elastomeric material from the second gate (49) into a second molding space (42) for molding the soft portion (20) to fill the molding space (42).
