A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

Head for an oral care implement

A filament-transportation device has a plurality of tube elements for transporting filaments from an intake area to an outtake area via an airstream generated by underpressure or overpressure. Each tube element has an end orifice. A baffle-plate unit has a baffle plate having a through-hole, a top surface opposite to the end orifices to stop the transport of the filaments, and a bottom surface opposite to the top surface. The baffle plate includes baffle plate elements associated with the end orifices. Each of the baffle-plate elements has a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending between the top and bottom surface. There is a plurality of bridge elements, each having a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending from the top surface of the bridge element to the bottom surface of the bridge element. The through-hole is defined either by the side surfaces of at least two baffle plate elements or by the side surfaces of at least one baffle plate element and of a side surface of at least one bridge element not facing an end orifice of a tube element, which bridge element connects two spaced apart baffle plate elements from the plurality of baffle plate elements.

Filament transportation device

A process for creating multiple tufts for a tufted article comprises directing the initial filament bundle into a first channel, causing the bundle to move through the first channel while splitting the bundle into a plurality of tufts according to a predetermined pattern, and directing the plurality of tufts into the plurality of second channels such that each of the plurality of tufts has its own second channel. An apparatus comprises a first plate having a first channel for receiving a filament bundle, a splitting element for separating the bundle into the plurality of individual tufts, a second plate having a plurality of second channels for receiving the plurality of tufts, and a driving means for moving the filaments in the channels.

Process and apparatus for creating tufts for tufted article

A method for producing a toothbrush comprises providing a head, a neck portion, and a handle; providing a coupling element; and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed. The individual parts of the toothbrush to be formed can be produced in parallel or successively, wherein some of the parts can be produced by injection molding. A toothbrush formed by the method comprises a head, a neck portion, and a handle; these elements can be produced as building blocks separately and may be connected to one another via a coupling element to form an inseparable connection.

Manual toothbrush

Methods of producing toothbrush handles having an inner cavity are provided.

Method for producing a toothbrush handle having an inner cavity

A personal care article, such as a toothbrush having an inner cavity made in one molding process.

Toothbrush having an inner cavity

A toothbrush comprises a head, a neck portion and a handle, wherein the neck portion and the handle portion are connected to one another via a coupling element. The connection is constructed as an inseparable connection, i.e., after being combined once, the neck portion and the handle cannot be separated without the brush being destroyed by such separation. A method for producing such a toothbrush may comprise the following steps: providing a head, a neck portion, a handle, and a coupling element, and combining the neck portion to the handle by the coupling element so that an irreversible connection is formed.

A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements, such as bristle tufts may be fused by heat and may be placed in a mold cavity to be over-molded.

Brush head and method and tool for producing same

A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.

A toothbrush having a handle, a head with oral care elements and a neck connecting the head with the handle is described. The toothbrush has a base structure of the handle, and the neck and the head are formed by a hard plastic component. Said basic structure of the handle is covered, at least in part, by a first soft plastic component. Said head including a second soft plastic component and said neck including a through-opening, wherein at least one section of a boundary wall of the opening is provided with an elastic muscle.

Toothbrush

A toothbrush head with a bristle support to which a plurality of tuft-shaped cleaning elements are affixed is described. The bristle support including at least one movable rocker having a first end attached to it on the side remote from a handpiece and having a free second end which is on the side close to the handpiece. Said rocker carrying at least one row of cleaning elements. At least the cleaning elements arranged on the rocker furthest from a longitudinal center plane of the toothbrush head have their free ends inwardly tilted towards said longitudinal center plane at an acute angle.
