Disclosed is a toothbrush with oligodynamic properties. This is achieved with a small current produced as a result of the dissimilar materials from which it is constructed. A small piece of zinc metal. attached to the device at a specified location acts as a sacrificial anode in order for any corrosion which will naturally occur, to occur at the replaceable anode, and nowhere else on the toothbrush. The bristles of the tooth brush are much longer than those of a conventional toothbrush in order to spend a longer period of time in contact with the teeth and gums thereby causing the desired effect to be more pronounced.

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 computer system receives user-specified settings for a custom formulation of a personal care product, obtains manufacturing parameters for the custom formulation based at least on part on the user-specified settings for the custom formulation; and transmits the manufacturing parameters to a manufacturing computer system. The manufacturing parameters are configured to initiate or guide a manufacturing process to produce the custom formulation of the personal care product. The computer system also receives user-specified settings for a personal care device having at least one computer-controlled component, obtains operational parameters for the personal care device based at least in part on the user-specified settings for the personal care device; and transmits the operational parameters to a remote computing device in communication with the personal care device. The operational parameters are configured to modify at least one operational characteristic of the at least one computer-controlled component of the personal care device.

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.

The present invention relates to a method for molding a shape of bristles of a mascara brush for eyelashes, a mold in used in the method. Two strands of iron cores are twisted and brush bristles respectively having dorsal portions are radially spread between the twisted iron cores through post-process so as to form a mascara brush, wherein the dorsal portions are formed by the brush bristles of the same length on the basis of the iron cores without difference in the length of the brush bristles, so that a mascara solution contained in the dorsal portion does not run down when being applied to eyelashes, and the mascara provides more volume and a beautiful eyelash make-up when a sufficient amount of the mascara solution is applied.

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).

A toothbrush is provided, including an elongated handle and a brush head supported by the handle. The brush head has a base and a plurality of bristles that extend from the base to form a contact surface elevated from the base. The handle includes a thumb press section that include ridges and flat sections. The toothbrush may include a skeletal structure with an overmoulding encasing the skeletal structure. The overmoulding may form the outer surface of portions of the toothbrush, including the thumb press section.
