An adaptor for being coupled to a drive shaft of an oral care device handle having an essentially cylindrical drive shaft coupling end and for being coupled to an oral care device attachment is provided, the adaptor comprising: a second separable coupling part configured for coupling with a first separable coupling part provided at a motion transmitter of the oral care device attachment; and a coupling unit having a top plate and one at least partly deformable essentially cylindrical wall element, or at least two elastic or deflectable wall elements, extending from the top plate, wherein the coupling unit defines an essentially cylindrical receiver receptacle for receiving and coupling with the essentially cylindrical drive shaft coupling end.

Provided is a hair-guiding element (10) for an electric shaver. The hair-guiding element has a skin-contacting surface (12) for contacting skin, and a cutting element-facing surface (14) for facing a cutting element (16), with the cutting element-facing surface facing in an opposite direction with respect to a direction faced by the skin-contacting surface. The hair-guiding element's periphery provides the hair-guiding element with a toothed profile comprising teeth (20) arranged along a main axis (MA) of the hair-guiding element, with the teeth each comprising part of the skin-contacting surface and part of the cutting element-facing surface. Slots (26, 26', 28, 28') separate neighboring teeth (20) from each other along the main axis (MA). The slots include pairs of slots (26, 28; 26', 28'). Each of the pairs of slots includes a longer slot (26; 26') and a shorter slot (28; 28'). Further provided is a hair-cutting assembly (10, 16) comprising the hair-guiding element and the cutting element, and an electric shaver comprising such a hair-cutting assembly. Additionally provided is a method of manufacturing the hair-guiding element.

Provided is an etching method that includes providing a metallic substrate (100) on which an etch-resistant material is arranged to mask the metallic substrate, through which etch-resistant material apertures (126) are defined. The etch-resistant material comprises a continuous region (128) that extends continuously between and surrounds the apertures. The etching method includes etching the metallic substrate, with the etching including delivering an etchant to the metallic substrate through the apertures so that discrete recessed regions in the metallic substrate are initially etched beneath the apertures. The etch-resistant material is resistant to the etchant. The etching is continued until at least some of the discrete recessed regions merge beneath the continuous region of the etch-resistant material so that the continuous region extends over a location of the metallic substrate located in-between the initially formed discrete recessed regions, at which location metallic material of the metallic substrate is removed when the discrete recessed regions merge to form one or more merged etched regions (130). The etching leaves behind a portion (132) of the metallic substrate, which portion of the metallic substrate still remains beneath the one or more merged etched regions. Also provided is a method of manufacturing a foil, comb or blade for an electric shaver, with the method comprising implementing the etching method. Further provided is an article obtainable by the etching method or the method of manufacturing the foil, comb or blade.

A personal care attachment for a personal care handle, the personal care attachment having an outer housing, a head unit having a head arranged for being driven into motion relative to the outer housing, in particular into an oscillatory motion, and a driver having a first end being coupled with the head and a second end arranged for being coupled with a drive shaft of the personal care handle, and a magnetic force unit having at least one first magnetically interacting element provided in fixed relationship with the outer housing and at least one second magnetically interacting element provided in fixed relationship with either the head or the driver, wherein the magnetic force unit is arranged to provide a force that biases the second end of the driver away from the head so that the head is in a maximum deflection state, in particular wherein the personal care attachment comprises a stopper that defines the maximum deflection state.

The present disclosure is concerned with a method of making an insert for an injection molding machine comprising the steps of providing a metal block, removing material from the metal block by eroding and/or milling so that at least one depression is formed for at least partly defining a mold cavity for molding a first component of a two-component plastic part, the depression being defined by at least one bordering wall of the metal block, where between a base surface of the depression and at least a portion of the bordering wall a material transition area is present having a first radius, removing material from the material transition area by applying laser light so that the resulting material transition area has a second radius smaller than the first radius.
