A method of sanitizing a toothbrush. The method may include delivering a sanitizing fluid from a reservoir of a toothbrush that comprises a store of the sanitizing fluid to bristle tufts of the toothbrush solely via capillary action, wherein each of the bristle tufts comprises a plurality of bristle filaments so that the sanitizing fluid wicks upwardly along the bristle tufts within spaces between the bristle filaments to sanitize the bristle filaments.

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 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.

A toothbrush having a brush body and a bristle carrier that is produced from a hard material using an injection molding method and having injection-molded bristles that protrude from the bristle carrier. The injection molded bristles are produced from a bristle material using the injection molding method. The bristles have a bristle stem and the bristle carrier has a small carrier plate or is formed by the small carrier plate that is produced from a hard material using the injection molding method and fastened on the brush body. The hard material of the bristle carrier or the hard material of the small carrier plate is harder than the bristle material.

An interdental brush comprising an interdental brush bar and a grip, the interdental brush bar having a central shaft and a joint portion, the central shaft surface axially staggering a plurality of first bristle sets and a plurality of second bristle sets, the first bristle set has two first bristles, and the second bristle set has two second bristles, and each of the first bristles is connected with an adjacent second bristles to form a squeegee. The grip connects the joint portion, and the squeegee can increase the contact area with the teeth to enhance the cleaning effect.

An interdental brush includes a handle, a shank extending therefrom, and a bristle portion disposed around the shank. The bristle portion has a plurality of bristle units, each of which has a loading surface facing the handle and having a diameter larger than a diameter of the shank, and a surrounding wall extending from the loading surface toward a direction opposite to the handle with the extent progressively decreasing therefrom. The loading surface and the surrounding wall converge at a brim. The gradually-reduced arrangement of each surrounding wall facilitates an easy entrance into slits between teeth and provides each loading surface and brim with sufficient support to scrape and remove food debris and tartar while pulling the brush out. The revolution of bristle units around the shank helps the brush touch and massage gingivae in a large area, thereby increasing the effect of cleaning teeth and convenience of use.

Method of making soft interdental brushes, which relates to the field of daily necessities and solves the problems of unsightly fracture points and causing skin scratches at the fracture points with the current producing process. The method includes forming a receptacle frame with technical points as follows: a receptacle plate for organizing the brushes and receiving columns for fixing the brushes, the receptacle plate and the receptacle columns are fixedly attached; The method also adopts an interference fit approach to collect the brushes through the receptacle frame, meanwhile, the material after the injection will be cut off once the brushes are received by the receptacle frame. Compared with the traditional technology, the utility model makes the soft interdental brush more convenient to pick off, furthermore, there will be no residual connecting strips on the brush, so that the brush will not cut the skin while be more artistic.

A tool for attaching a treatment head to a wash media element of a vehicle wash component includes a nose portion and a handle portion. The nose portion is sized to pass through an opening in the wash media element. The nose portion includes a slot for receiving and retaining a base portion of the treatment head to secure it to the wash media element such that the nose portion and treatment portion are disposed on opposite sides of the wash media element.

Provided is an interdental cleaning tool which has a simple configuration and can effectively prevent an occurrence of breakage of a core base portion when inserting the interdental cleaning tool into an interdental space or during interdental cleaning without reducing productivity of the interdental cleaning tool, and provided is a method for manufacturing the interdental cleaning tool. An interdental cleaning tool (1) includes: a base portion (10) made of a synthetic resin; and a soft portion (20) made of an elastomer, the base portion (10) having a handle base portion (11) and a core base portion (12), the soft portion (20) having at least a cleaning soft portion (21) that covers the core base portion (12), in which a handle portion (3) as a grip is constituted by the handle base portion (11), and a cleaning portion (2) for interdental cleaning is constituted by the core base portion (12) and the cleaning soft portion (21), wherein two or more cleaning portion recesses (14) which penetrate the cleaning soft portion (21) and form core base portion recesses having a maximum depth d of 0.01 mm or more and 0.085 mm or less in the core base portion (12) are formed in each of a first side portion and a second side portion of the cleaning portion (2) at intervals in an axial direction of the cleaning portion (2).
