A method of making a razor cartridge including providing at least one razor blade having a cutting edge extending along a length of the razor blade and printing at least one printed object on the length is provided. The razor blade is positioned between the guard and the cap where the visible surface of the at least one razor blade includes a printed object. The printed object may extend continuously along the length of the razor blade and/or may have multiple portions having a comb-like structure. The printed object appears as a solid object to a viewer's naked eye. The solid object includes a plurality of printed ink dots not visible to the viewer's naked eye. The printed object of flexible, polymer ink may act as a guard element on the razor blade which helps with glide and to manage a user's skin (e.g., bulge) during shaving.

Razor blade with a printed objected

A razor blade having an improved lubricious material deposited thereon and a method of making a razor blade for a razor cartridge having such a material disposed thereon are described herein. A novel printing process and printing material are provided where at least one printing material is deposited on one or more razor blades via a printing process which includes one or more print heads for printing the at least one printing material and forming at least one printed object on a tip or one or more sides of the razor blade. The printing material may comprise about of about 0.25% solid to about 50% solids by weight of composition of telomer and further desirably comprises glycerol and/or an antifoam material. Optimizing coverage of the printing material may be achieved by changing materials, print heads, the firing frequency of the print head or angling or rotating the print heads.

Printed lubricious material disposed on razor blades

A razor cartridge, a razor blade, and a process of producing a razor cartridge and razor blade is provided including at least one blade positioned between the guard and the cap where the visible surface of the at least one razor blade includes a printed object wherein the printed object has a height dimension of from about 0.04 mm to about 0.60 mm. The printed object may extend continuously along the length of the razor blade and/or may have multiple portions having a comb-like structure. The printed object appears as a solid object to a viewer's naked eye. The solid object includes a plurality of printed ink dots not visible to the viewer's naked eye. The printed object of flexible, polymer ink may act as a guard element on the razor blade which helps with glide and to manage a user's skin (e.g., bulge) during shaving.

Razor blade with a printed object

A razor cartridge including a guard at a front portion of the cartridge, a cap at a back portion of the cartridge, at least one blade positioned between the guard and the cap, a top surface and an opposing bottom surface, and a lubricating member positioned in the cartridge at the top surface. The lubricating member has a visible surface with a visible surface area. The visible surface includes a printed lubrication control structure on the visible surface of the lubricating member. The printed lubrication control structure is formed from a UV curable ink and covers a portion of the visible surface area creating a covered portion and an open portion.

Razor cartridge with a printed lubrication control member

A razor cartridge including a guard at a front portion of the cartridge, a cap at a back portion of the cartridge, at least one blade positioned between the guard and the cap, a top surface and an opposing bottom surface, and a lubricating member positioned in the cartridge at the top surface. The lubricating member has an exterior surface with a visible surface and a non-visible surface. A printed support structure is provided on the exterior surface of the lubricating member. The printed support structure covers a portion of the exterior surface to provide structural integrity for the lubricating member.
