An oral care implement having a handle, and a head having a main body that is coupled to the handle. The head may include a release component coupled to the main body. The release component may include a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 150° C. The oral care implement may include a plurality of tooth cleaning elements. A method of forming an oral care implement which includes injection molding a composition comprising a graft polymer onto a head of an oral care implement at a temperature equal to or greater than 130° C. to form a water-dissolvable polymer matrix.

Method of forming an oral care implement

The invention relates to a brush, in particular an interdental brush, which comprises a bristle-carrying stem defining a longitudinal direction and having an elongate support core, a bristle area having bristles projecting from the bristle-carrying stem, and a neck element connecting the support core to a handle, wherein the handle, the support core and the neck element are injection moulded integrally from a first plastics component, and wherein a second plastics component in the form of an integral layer and the bristles projecting therefrom is mounted on the support core. The invention also relates to corresponding product groups and to a corresponding method.

Method for producing brushes, in particular interdental brushes, and brush, in particular interdental brush, and product group comprising a plurality of brushes

Described herein is an oral care implement comprising a handle, and a head having a main body that is coupled to the handle, the head comprising a release component coupled to the main body, the release component comprising a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 150&#xb0; C., and a plurality of tooth cleaning elements.

Oral care implement

A grip body of a body care article, such as toothbrush, includes a grip part, a neck part, and a head part. The grip body includes a first and a second material component of a thermoplastic plastic. Manufacturing of the grip body is performed via an injection moulding tool with at least one tool cavity, and the grip body including a first, second, and third material component of a first, second, and third thermoplastic material, respectively.

Method for producing a toothbrush, and toothbrush

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.

Toothbrush with injection-moulded bristles and method and apparatus for producing the same

The invention relates to a brush, in particular an interdental brush, which comprises a bristle-carrying stem defining a longitudinal direction and having an elongate support core, a bristle area having bristles projecting from the bristle-carrying stem, and a neck element connecting the support core to a handle, wherein the handle, the support core and the neck element are injection molded integrally from a first plastics component, and wherein a second plastics component in the form of an integral layer and the bristles projecting therefrom is mounted on the support core. The invention also relates to corresponding product groups and to a corresponding method.

The brush according to the invention has a bristle carrier, which is produced by injection molding, and bristles, which are produced from a bristle material likewise by injection molding. The bristle carrier is provided with at least one distributing channel for the bristle material. The bristles are formed integrally with the bristle material in the distribution channel.

The invention relates to a method and a device for producing parts that are made up of more than one component. The first part () is produced in a first plane () and then transported by a transfer system () into a second plane ().
