Toothbrush

A brush head for an electrically driven toothbrush is provided herein. The brush head includes a holding part connected to a carrier part, at least one bristle bundle formed by bristle filaments, and a resiliently soft cleaning element. The carrier part includes passage bores, through which the bristle bundle and resiliently soft cleaning element project, and each is fixed to the carrier part by way of a thickened portion formed by a filament material or a resiliently elastic material, respectively. A method of producing a brush head is also provided, including preparing the carrier part as a separate component with passage bores, fixing the bristle bundle and the resiliently clastic cleaning element to the carrier part with a thickened portion provided on the bristle bundle and the resiliently elastic cleaning element, respectively, and connecting the carrier part to the holding part.

Brush head, in particular for an electrically driven toothbrush, and method for the production thereof

A brush head for an electrically driven toothbrush includes a holding part () that provides at least one connecting element for mechanically coupling the brush head to the electric drive of the toothbrush, wherein the holding part () integrally forms a stud () defining a pivot axis (S) about which the brush head is pivotable, and a plate () which at its end facing away from the stud () carries at least one bristle bundle () which at its attachment-side end includes a thickening () formed by surface melting. For improving the brush head, a substantially disc-shaped bristle carrier () is connected to a holding part () and includes a bore that is penetrated by the bristle bundle ().

Brush head for an electrically driven toothbrush

A method for making a toothbrush including a handle, a head including at least one cleaning element extending therefrom, and a hinge arranged between the head and the handle, said hinge including a joint between the handle and the head of a harder thermoplastic component covered by a softer thermoplastic component is provided, the method including: forming a base body by injection molding of a first thermoplastic material forming one of the handle or the head, and injection molding of a second thermoplastic material for forming the other of the handle or the head to thereby fuse the second thermoplastic material against the first thermoplastic material; placing the base body into a further mold; and injection molding the softer thermoplastic component for covering the joint.

Method for making a toothbrush

A toothbrush is provided including: a handle; a head attached to the handle; a plurality of tooth cleaning elements projecting outwardly from a first surface of the head; and a cleanser including at least one projection protruding outwardly from a second surface for removal of microbial and other debris from soft tissue in the mouth, which second surface is arranged opposite to the first surface; wherein the at least one projection is made of a hard component; wherein the second surface is an elastomeric second surface.

Oral care implement

A method for producing a brush, wherein a filament bundle strand is unwound from a spool and moved past a cutting device that severs a predetermined length of the strand for connection with the bristle carrier of the brush. In order to increase productivity, airflow is used to transport the unwound strand and the severed strand length. A pressure or vacuum source is provided which communicates with the take-off guide channel and/or the guide channel and which produces in the respective channel an airflow that is effective in the direction of transport of the strand.

Method for producing a brush

A method for producing toothbrushes by way of injection molding is provided, wherein a brush body is formed in a mold cavity, bristle filaments are connected to the brush body for forming bristles, and at least one flexible element extending substantially in parallel with the bristle filaments is preferably formed by injection onto the brush body. The contouring and/or finishing of the bristle filaments can be carried out without any impairment by the flexible cleaning elements. During the finishing operation, the flexible cleaning element is removed from the operative area of the finishing tool.

Method for producing brushes and apparatus for performing said method

The present invention relates to a method of producing brushes, especially toothbrushes, which comprise a brush body and at least one bristle bundle composed of a plurality of oriented bristle filaments, the method comprising the steps of introducing the bristle bundle into a channel which is formed on a moulding tool component, partially melting the bristle bundle at its fixing-side end so as to form an enlargement, closing the moulding tool and filling it with a flowable material. According to a first aspect of the present invention, the method is further developed in that at least a weakened length area of the bristle filaments, which is created when the bristle bundle is partially melted, is completely surrounded by the enlargement. According to a further aspect of the present invention, hot gas is used for forming the enlargement. The device for producing brushes, especially toothbrushes, which is suggested for executing the method in accordance with the present invention, comprises a moulding tool component which is a constituent part of a moulding tool and which is provided with at least one channel for holding a bristle bundle, and a mould filling device which communicates with the moulding tool component as well as a heating device which is associated with the moulding tool component and used for partially melting one end of the bristle bundle. In order to achieve short processing times, at least one hot-gas nozzle is provided which is directed towards the moulding tool component.
