摘要： 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.

摘要： According to this invention a flexible razor head is provided which features a flexible cap and blade support portion with the blade support portion featuring a segmented guard bar with the spaces separating the segment correlating to the spaces or areas of reduced thickness in the cap. Corrugations present in the blade support portions enable the blade support portion to lengthen in response to shaving forces.

摘要： An improved twin blade razor system having a unitary member positioned between the pair of blades for both spacing the blades and ejecting shaving debris from that space. The unitary member, which may conveniently be of injection molded plastic, includes a spacer portion, an ejector portion, and biasing means connecting the ejector portion and the spacer portion for biasing the ejector portion to a normally retracted position relative to the blades and spacer. The ejector portion extends across in front of but is substantially discontinuous behind the spacer portion, resulting in a compact front-to-rear configuration for the unitary member which may be housed in a relatively compact twin blade system. The ejector portion is manually displaceable to an advanced ejecting position. The biasing portion may be one or more beam springs connected and configured to reduce distortion and/or stressing of the relatively moving portions of the member during actuation.

摘要： A safety razor contains a blade cartridge in which two blades are rigidly secured. The cartridge has a seat member with an integral blade edge guard disposed transversely along its forward margin. A first razor blade is disposed on a planar surface of the seat member and has its cutting edge located rearwardly of the guard. A second razor blade having a cutting edge located parallel to and rearwardly of the first blade edge is in contact with a mating surface of a cap member. The cap member is secured to the seat member thereby clamping the blades in desired position. The blades are maintained at a predetermined distance apart by spacing means and the guard member has a plurality of projecting teeth transversely arrayed across the guard member forming a comb guard.
