Replaceable shaving assemblies are disclosed that include a razor cartridge having a lubricating strip geometry that is designed to work with the blade geometry and other cartridge features to provide a close, comfortable shave over the intended lifetime of the cartridge. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems and methods of manufacturing these cartridges.

One embodiment of a dual sided razor comprises a handle and a cartridge attached to the handle, the cartridge further comprising a first shaving side and a second shaving side, the cartridge being switchable relative to the handle between the first and second shaving sides.

In some embodiments, the present disclosure provides a razor assembly including a razor cartridge, razor handle, and recovering force-providing unit. The razor cartridge includes a shaving blade having a cutting edge and a blade housing receiving the shaving blade longitudinally. The razor handle is connected to the razor cartridge rotatably about a first rotational axis parallel to longitudinal direction within a rotation range. The recovering force-providing unit provides the razor cartridge rotated about the first rotational axis from a rest position with recovering force returning the razor cartridge to the rest position. The rotation range includes a first pivot section between the rest position and first angle, and a second pivot section between the first angle and a greater second angle. The recovering force increases as the razor cartridge rotates with an increasing rotational angle, at an increasing rate that differs between the first and second pivot sections.

A shaving device comprising a head assembly having a support member and a blade cartridge. The support member is configured to be detachably coupled to a handle. The blade cartridge has a first and a second face wherein at least one of the first or second faces comprises at least one razor blade. The blade cartridge is configured to be rotatably coupled to the support member about a pivot axis such that the blade cartridge is pivotable by a user to select one of the first or second faces.

A razor assembly includes a razor cartridge, a connecting head, a razor handle and a restoring force provider. The razor cartridge includes a blade housing for housing shaving blades in a first direction. The connecting head has one side detachably coupled to the razor cartridge. The razor handle includes a head adapter coupled to the connecting head to be rotatable about a rotational axis perpendicular to the first direction, and a grip extending from head adapter. The restoring force provider includes a first magnet disposed on another side of the connecting head which co-rotates with the connecting head about the rotational axis, and a second magnet disposed at a fixed position on the razor handle such that a magnetic force between the one or more first magnets and the one or more second magnets biases the connecting head toward a neutral rotation position with respect to the razor handle.

A razor handle. The razor handle include a main body and a pivoting head pivotally coupled with the main body about a pivot axis. The pivoting head can have a substantially trapezoidal prism shape and can include a base member and a cover member that overlies the base member in a mating relationship and can have an internal compartment. The cover member can have a skin interfacing face.

This invention relates to a novel application of liquid-infused surface materials (LISM) to at least a portion of one or more surfaces of razor components (e.g., frame, housing, clips, blade supports, blade body, blade edge, lubricating bodies, guard, handle, grip, button). If applied to a skin contacting surface of a component, the one or more LISM layers may generally be abrasion-resistant, long-lasting or non-erodible, desirably elevating shaving performance, such as glide, comfort, rinsing, and cleanliness, while also simplifying the manufacturing process.

A blade assembly including at least one blade support and at least one blade element having a cutting edge portion. The blade support includes a base portion and a flat portion. The flat portion extends at an angle with respect to the base. The at least one blade is attached to the flat portion of the blade support. The blade assembly further includes a lubricating element. The lubricating element is attached to the flat portion and the at least one blade element.
