An adapter for coupling each of a razor handle and a razor cartridge together is provided. The adapter includes a cartridge engaging portion and a handle engaging portion. The handle engaging portion comprises at least one wall that defines a receptacle for receiving a razor handle and at least one handle protrusion extending from the at least one wall and configured to engage a central recess of a razor handle. The cartridge engaging portion is coupled with the handle engaging portion. The cartridge engaging portion comprises a stem that defines a first recess and a second recess for selectively engaging a first cartridge protrusion and a second cartridge protrusion and a tongue member slidably coupled with the stem and configured to contact a cartridge.

Shaving cartridge with enhanced rinsing
11628581 · 2023-04-18 ·

A razor that facilitates a user's removal of shaving lubricant, cut hairs, and other shaving-related debris, from around, and between, the razor's blade(s). A scoop at the upper portion of the razor's blade assembly funnels water to the blade channel in which the blades are affixed, and at least a portion of that water flows around and/or over the blade(s). The scoop captures, and directs through the razor's blades, a greater volume of water per unit time than can be achieved with an unmodified blade assembly. The cross-sectional area of the scoop's inflow mouth is greater than that of the blade channel's outflow mouth, thereby promoting a Venturi effect which increases the speed of the water's flow over the blades.

Dual double-edge razor

The present invention relates to a razor including a handle, a frame coupled to the handle, a spacer, a top cap, a first blade secured between the frame and the spacer, and a second blade secured between the spacer and the top cap, wherein the first blade is supported by a portion of a top surface of the frame and a portion of a bottom surface of the spacer such that a first profile of the first blade is convexly curved upward, and wherein the second blade is supported by a portion of a top surface of the spacer and a portion of a bottom surface of the top cap such that a second profile of the second blade comprises a curved central region that is convexly curved upward and a pair of curved side regions that are concavely curved downward on opposite sides of the central region.

METHOD OF RESETTING A DIGITAL COUNTER FOR A PERSONAL CARE APPLIANCE

A method of resetting a digital counter for a personal care appliance by sending an electrical output signal from an optical sensor to a control circuit. The electrical output signal is compared to a predetermined value with the control circuit or a change in the electrical output signal from the optical sensor is detected over time. A signal is sent to a consumer user interface by the control circuit based on the electrical output signal and the predetermined value or based on the change in the electrical output signal from the optical sensor. The digital counter is reset based on an input signal from the consumer user interface.

Press and methods for cutting and folding a safety razor to form a 2-blade system for a razor head, and assembly
11628584 · 2023-04-18 ·

A shaving head that doubles as breaking mechanism to break a safety razor blade into two pieces to form a 2-blade shaving razor. The shaving head includes a front component having a retention guide, a first position stop and a second position stop at a distance offset from the first position stop. The shaving head further includes a back component having a blade slot configured to receive a first blade portion and a second blade portion formed from breaking a double-edge safety razor blade such that the first blade portion has a different width compared to the second blade portion. The retention guide is configured to retain the first blade portion and the second blade portion in the blade slot responsive to the retention guide being at least partially inserted into the blade slot. The sharp shaving edges once installed form a shaving angle between 5 and 30 degrees, where the shaving angle is determined by where the blade is broken.

Shaving aid delivery systems for razors

A razor head, comprising a housing comprising one or more cutting elements, the housing further comprising a first window, and a second window; a substrate-based shaving aid delivery system, comprising a first reel that is rotatably mounted about a shaft, an actuator operationally coupled with the shaft, wherein at least part of the actuator protrudes externally from the housing via the first window; and a substrate carrying a shaving aid on its external surface.

Razor blades

A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has a thickness of greater than about 2.30 micrometers measured at a distance of four micrometers from the blade tip, a thickness of greater than about 4.26 micrometers measured at a distance of eight micrometers from the blade tip, and greater than about 7.93 micrometers measured at a distance of sixteen micrometers from the blade tip. A hard coating joined to the substrate has a thickness of 700 Angstroms to about 3500 Angstroms. An outer layer joined to a coated substrate is discontinuous. The outer layer may be produced from a dispersion comprising about 0.03 g/L or less of telomer or from about 0.5 % solids or less of telomer by weight of composition. The novel razor blade cuts at less than 100 % cutting efficiency using a single fiber cutting efficiency measure.
