Abstract
A shaving implement, such as a disposable cartridge or razor, comprises a shaving head which includes a skin-contacting element, in the form of a plurality of sections of flexible ridges. The ridges in each section are oriented alternately at positive and negative angles relative to the blade, in a herringbone pattern, and define flow-through recesses. Preferably, a ridge from each section is joined together with a ridge from an adjoining section, to form a chevron-shaped node between sections. When shaving, adjacent sections push areas of the skin in different directions, while the flow-through channels retain a layer of lubricating material on the skin, so that the cartridge provides a smooth, comfortable shave.
Claims40
A shaving implement for moving in a normal shaving direction, comprising:
- at least one razor blade having a blade edge extending in a direction perpendicular to said shaving direction;
- a shaving head which secures said at least one razor blade;
- and
- said shaving head including a skin-contacting element having leading and trailing edges parallel to said blade edge, wherein said skin-contacting element includes a plurality of adjoining sections, each section comprising a plurality of rows of parallel, flexible skin-engaging ridges, and wherein ridges in adjoining sections extend alternately at positive and negative angles relative to the direction of said blade edge.
A shaving implement comprising:
- at least one razor blade having a blade edge extending in a direction;
- a shaving head which secures said at least one razor blade, said shaving head being flexible in a direction perpendicular to said razor blade;
- and
- said shaving head including a skin-contacting element having leading and trailing edges parallel to said blade edge, wherein said skin-contacting element includes a flexible base secured to said shaving head and a plurality of skin engaging members extending from said strip, and wherein said skin engaging members define a plurality of flow-through channels extending from said leading edge to said trailing edge.
A shaving implement comprising:
- at least one razor blade having an edge;
- a shaving head made of a relatively rigid plastic material, wherein said shaving head secures said at least one razor blade and includes a cap portion and a guard portion;
- wherein at least one of said guard and cap portions has a recess including a seat portion and a joint-forming portion;
- an elastomeric skin-contacting element filling said recess and joint-forming portion to form a mechanical joint with said at least one cap and guard portion, wherein said skin-contacting element includes a skin engaging surface projecting from said recess and wherein said skin engaging surface comprises a plurality of flexible ribs extending forward of said guard portion and parallel to said blade edge.
