A cell of a brush making device for making at least a part of a toothbrush, having a pin unit having at least one pin, a pin holding sub-unit and a pin guiding sub-unit, the pin having a first section having a first end and a second section having a second end, the first section having a holding structure, and at least one spring section arranged between the first section and the second section, the pin holding sub-unit having a holding structure that is engaged with the holding structure of the pin for fixedly holding the pin, the pin holding sub-unit and the pin guiding sub-unit being arranged for being movable along a first direction towards and away from each other, and the pin guiding sub-unit having a channel for guiding at least a portion of the second section of the pin, the channel being inclined against the first direction.

Described herein is an oral care implement comprising a body having a head portion, a gripping portion, and a neck portion located between the head and gripping portions, a plurality of tooth engaging elements extending from the head portion, the body comprising a first component formed of a first hard plastic having a first ductility; and a second component formed of a second hard plastic having a second ductility that is greater than the first ductility.

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 of making a cleaning element carrier for a toothbrush comprises: providing at least two pluralities of loose filaments of a predefined length and different from one another in at least one of filament material, filament diameter, filament cross-section, filament shape, presence or absence of additives, presence or absence of a coating, and any combination thereof; providing a hole-perforation plate having a front surface, a back surface, a thickness therebetween, and a plurality of holes shaped and arranged according to a predetermined pattern; picking filaments from the pluralities of loose filaments; providing an energy source; arranging a plurality of bristle tufts in a fusing position in the hole-perforation plate so that ends of the bristle tufts are disposed at different distances from the energy source, wherein the distances are adjustable according to the at least one property, wherein the plurality of bristle tufts includes bristle tufts comprising an inner portion bristle tufts comprising a peripheral portion, and wherein a distance between the energy source and the ends of the bristle tufts comprising the inner portion is shorter than a distance between the energy source and the ends of the bristle tufts comprising the peripheral portion; applying energy from the energy source to the ends of the tufts until fuse balls are formed at the ends of the tufts; transferring the tufts to a molding position in the hole-perforation plate so that a distance between a bottom edge of at least one fuse ball of at least one bristle tuft and the front surface of the hole-perforation plate is different from a distance between the bottom edge of the fuse ball of said tuft and the front surface of the hole-perforation plate in the fusing position; over-molding the fuse balls with molten plastic material thereby forming a cleaning element carrier.

This disclosure relates to oral care appliances and methods of forming oral care appliances. A disclosed oral care mouthpiece includes a flexible membrane and a set of oral care elements attached to the flexible membrane. The set of oral care elements have a composition with a hardness of at least 50 Shore Type A (shA). Each oral care elements in the set of oral care elements has a minimum stiffness value higher than 410.sup.8 newton meters and lower than 610.sup.3 newton meters. The stiffness value and hardness of the oral care elements are both critical values for the disclosed appliances and methods. The stiffness value can be expressed as the product of the Young modulus of the oral care element and the moment of inertia of the oral care element divided by the length of the oral care element.

A makeup applicator head, adapted for applying cosmetic material on skin surface of user, includes an applicator body having at least an exterior surface portion forming a makeup surface which is a continuous surface made of rigid material and configured for attaching the cosmetic material thereon. The makeup surface has at least an end portion makeup surface and at least one side portion makeup surface extended from the end portion makeup surface towards the connection end.
