Embodiment Construction

[0017] The present invention provides a novel method comprising a laser to produce markings on razor blades, in particular providing laser markings on the surface of the razor blades. Laser-generated marking offers several advantages over ink or other traditional marking techniques in that the method is faster, can be performed on a variety of materials, may be more legible over time, helps provide accurate date codes, Provides more font options without damaging or distorting the product.

[0018] The term "laser" as used herein implies an acronym denoting light amplification by stimulated emission of radiation. Laser light is produced by raising the energy level of atoms to an excited state, which releases light when they fall back to their original energy, or ground state. Once this beam is created, it is somehow magnified to create a focal point. As the atoms start to move, they produce faint light, and as more and more energy is added, the light waves become more concent...

Abstract

This invention relates to razor blades, and more particularly to laser produced markings on razor blades and processes thereof.

Description

technical field [0001] This invention relates to razor blades, and more particularly to markings on razor blades and methods thereof. Background technique [0002] Razor blades (eg, double-edged) are generally known in the art to be visibly marked on the outer surface, if any, with an ink such as a solvent-based ink. These inks are currently applied to the surface of the blade by printers and printing methods. In some cases, both sides are marked with ink. Ink markings are usually trade names (e.g., ), other text, designs and / or graphics. [0003] One disadvantage of prior art ink markings is the hazardous nature of printing solvent-based inks themselves and solvent thinners. Ink materials may be considered hazardous if inhaled and highly flammable. Another disadvantage is that in some cases, the markings are removed and are not permanent. In other cases, markings can be printed in an inconsistent manner. For some printers, the method of printing inks uses too much e...
