摘要： The present invention relates to a skin treatment sheet comprising a substrate with a plurality of apertures wherein the sheet has a first surface and an opposing second surface. The apertures have a first and second inner perimeter and a cutting edge along at least a portion of the first inner perimeter. The skin treatment sheet has a stability ST which is the ratio of the average cross-sectional substrate area Ax and the total aperture area A1. Moreover, the present invention also relates to a skin treatment device comprising this skin treatment sheet.

摘要： The present invention relates to a cutting element having a substrate with at least one aperture which includes a cutting edge along at least a portion of an inner perimeter of the aperture. The cutting edges have an asymmetric cross-sectional shape with a first face, a second face opposed to the first face and a cutting edge at the intersection of the first face and the second face. Moreover, the present invention relates to a hair removal device including such cutting elements.

摘要： A razor blade including a blade body, an expanded coating structure arranged on a surface of the blade body so as to cover the blade body at least partially, the expanded coating structure including one or more expanded polymer microspheres, at least one of the one or more expanded polymer microspheres including a gas encapsulated within a hollow thermoplastic polymer shell. A process for fabrication of same, including providing a blade body, depositing a liquid suspension, the liquid suspension including expandable polymer microspheres dispersed in a liquid uncured polymer precursor, each expandable polymer microsphere including a gas encapsulated within a hollow thermoplastic polymer shell, on a surface of the blade body to obtain a deposit, and expanding at least a portion of the expandable polymer microspheres in the deposit to obtain an expanded deposit including one or more expanded polymer microspheres arranged on the surface of the blade body, the liquid uncured polymer precursor being configured to remain uncured during expansion of the expandable polymer microspheres. A skincare device including such a razor blade. A process of fabricating same, including attaching such a razor blade to a cartridge.

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip and novel dimensions is provided. The substrate has dimensions of volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The substrate is coated with one or more materials and has novel volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The thickness of the substrate at 2 micrometers back from the ultimate tip is at or below about 0.977 micrometers and at or below about 1.173 micrometers for a coated substrate at the same distance. These dimensional values are measured robustly with an atomic force microscope and provide reduced cut forces for improved blade performance.

摘要： Razor having a hair-severing member having a plurality of sawing teeth arranged along a hair-severing edge of the hair-severing member. Each sawing tooth has a tooth tip and tooth edges mutually connected via the tooth tip. The hair-severing member is mounted for sawing through hairs present on the skin by means of the sawing teeth by moving each sawing tooth in a local direction of extension of the hair-severing edge at the position of the respective sawing tooth. A drive is coupled to the hair-severing member for driving the hair-severing member such that the sawing teeth move with an average velocity larger than or equal to 10 m/s. The spacing between the tooth tips of two successive sawing teeth is between 20 μm and 150 μm.

摘要： When two conventional safety razor double-edged blades are superposed on top of each other, there is no space in between them to pass the shaving residues. The presently invented safety razor double-edged blade is equipped with several spaced protuberances on its surface. When two of these present invented blades are overlapped, there is a space between them to pass the shaving residues to be rinsed away by running water. Therefore two, three or more of them can be superposed on a single razor blade holder to allow the user to experience all the benefits of a multi-blade razor cartridge in a safety razor blade system.

摘要翻译： 当两个传统的安全剃刀双刃刀片重叠在一起时，它们之间没有空间通过剃刮残余物。 本发明的安全剃刀双刃刀片在其表面上装有几个间隔开的突起。 当这些本发明的叶片中的两个重叠时，它们之间有一个空间，以通过流动的水冲洗掉的剃刮残余物。 因此，它们中的两个，三个或更多个可以重叠在单个剃刀刀片架上，以允许用户在安全剃刀刀片系统中体验到多刀片剃刀刀片架的所有优点。

摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has thicknesses of 1.60-1.75 micrometers and 9.25-10.00 micrometers measured at a distance of four and forty micrometers from the blade tip, respectively. A ratio of the thickness measured at four micrometers to the thickness measured at forty micrometers is between 0.165-0.185. The substrate thickness is about 2.70-3.00 micrometers at eight micrometers from the blade tip, about 4.44-5.00 micrometers at sixteen micrometers from the blade tip with a thickness ratio measured at four micrometers and eight micrometers between 0.56-0.62, and a thickness ratio measured at four micrometers and sixteen micrometers between 0.32-0.40. The blade edge shape is defined by equation w=adn where “a” is between 0.50-0.62 and “n” is between 0.76-0.80. An included angle of less than 7° is measured at a distance of forty micrometers or greater from the blade tip. A nitrided substrate may also be provided.
