摘要： The present invention relates to a personal care device such as an electric hair cutter like shaver or toothbrush, and to a method of manufacturing such personal care device. More particularly, the personal care device comprises a handle and a function head supporting at least one personal care tool, said function head being attached to said handle, wherein at least one of said handle and said function head includes an outer metal shell formed in one piece with an integral, homogeneous, seamless structure having a ring-like or sleeve-like shape with closed annular cross-sections. Said outer metal shell includes at least one undercut portion which is formed with a hydraulic pressure forming step applying hydraulic pressure onto a side of a metal shell blank positioned in a mold to deform the metal shell blank and press an opposite side of the metal shell blank against said mold to adopt a contour of the mold.

摘要： The invention relates to an electrically operated shaving apparatus (1) having at least one cutting device that can move in or out in a first guide path (19) by means of a sliding switch (9) on a shaver casing (2). The cutting device consists of a blade casing (18) and a long hair cutter (20) on the blade casing (18) that is fed into a second guide path (20) which can be driven by a drive mechanism. Between the shaver casing (2) and the long hair cutter (10) is situated a transmission mechanism (21) that enlarges the displacement path (b) of the long hair cutter (10). According to the invention, the transmission mechanism (21) consists on the one hand of a fixed stop (31) attached to the shaver casing (2) and, on the other hand, to a sliding element (24) that can be slid crosswise to the displacement path (d) of the long hair cutter (10) into a third guide path (22). The sliding element operates in connection with the stop (31) by means of a ramp (26) attached to the sliding element (24) and tilted at an angle alpha vis-a-vis the sliding direction. The sliding element (24) is connected by means of a deflection device (25) to the casing part (17) of the long hair cutter (10). The invention provides for the creation of a transmission mechanism (21) that is very easy to manufacture and has very few components that enables the long hair cutter (10) to be lifted out quickly with little movement on the sliding switch (9).

摘要： The present invention relates to a personal care device such as an electric hair cutter like shaver or toothbrush, and to a method of manufacturing such personal care device with an outer metal shell, comprising the steps of forming the outer metal shell into a desired shape and mounting functional components for performing or helping to perform a personal care treatment into and/or onto said formed outer metal shell. Said forming the outer metal shell includes a hydraulic pressure forming step applying hydraulic pressure onto a side of a metal shell blank positioned in a mold to deform the metal shell blank and press an opposite side of the metal shell blank against said mold to adopt a contour of the mold, thereby forming the outer metal shell with the desired shape. Such hydraulic pressure forming step allows for deforming the metal shell blank into complex three-dimensional shapes without having the problem of getting mechanical forming tools such as punches, pusher or movable core elements out of the concavities of the metal shell. More particularly, the outer metal shell may include one or more undercuts formed by applying hydraulic pressure onto the shell portions desired to have such undercut shape, wherein the outer metal shell may be formed in one piece with a homogenous, integral and seamless structure having a closed annular cross-section.

摘要： The invention refers to an electric shaver (1) comprising a shaver housing (2), a shaver head (3) and at least one cartridge (10; 10a, 10b) mounted in or on said shaver housing (2). The adaption of the cutter element (6) to the contour of the skin to be shaved is improved by permitting at least one additional movement of the at least one cutter unit (4, 5) relative to the shaver head (3).
