A shaving razor adapter used to attach a shaving razor cartridge to a razor handle. The razor cartridge has a pair of distally positioned arc shaped receiving regions and a camming surface. The adapter engages the razor cartridge with a pair of outwardly facing arc shaped bearings for mating into said pair of arc shaped receiving regions of said razor cartridge. The adapter has a recess and a pair of detents for receiving and engaging the handle. The handle has a biasing member to engage the camming surface of said razor cartridge.

Adapter for attaching a razor cartridge to a razor handle

A method of making a razor blade unit is provided. The method includes the steps of: providing a plastic base member; providing a plastic upper member, the plastic upper member having a first surface and an opening in the first surface; securing a shaving aid member to the first surface of the upper member, the shaving aid completely surrounding the opening; inserting at least one razor blade between the plastic base member and the plastic upper member; and securing the plastic base member to the plastic upper member creating a plastic body having the at least one razor blade disposed in the plastic body.

Method of making a razor blade unit

A shaving razor blade unit that has a plurality of blades and a guard that includes two groups of rows of elongated, elastomeric fins arranged generally parallel to the cutting edges of the blades. The first group of fins has tips with generally uniform base to tip heights of a first dimension, and the second group in has tips with generally uniform base to tip heights of a second dimension, the second dimension being less than one fifth of the first dimension. Also disclosed are elastomeric guard fins having base to tip heights less than 0.15 mm, and the fins being the last skin engaging structure contacted by a user's skin before contacting the blades.

Shaving razor and blade unit with improved guard

A cartridge dispenser for razor blade cartridges including latches that retain cartridges in predetermined positions permitting connection to a handle connecting structure on a handle as the handle is moved toward the cartridge, each latch having a latch camming structure that is shaped and positioned to interact with corresponding handle camming structure so as to cause the latch to be deflected and to unlatch a cartridge as the handle is moved toward and connected to cartridge connecting structure of a cartridge. The dispenser also has blade unit dividers that extend from the base, are substantially perpendicular to the base, and define blade unit regions in which the blade units are received, and angled dividers that extend from the ends of respective blade unit dividers at acute angles with the base and define angled regions through which the blade units pass in delivery to and removal from the blade unit regions and in which the cartridge connecting structure is received.

Dispensing razor blade cartridges used with a handle

A safety razor system includes an elongated housing pivotably attached to a member connecting the housing to a handle. The housing is substantially rectangular, having arcuate end portions. A plurality of razor blades and a guard member extend from the upper surface of the housing and an annular retainer clip is disposed about the periphery of the housing serving to retain the blades onto the housing and position the blades relative to the guard member. The connecting member pivotably supports the housing by four coaxial bearing surfaces contacting mating surfaces on the housing during rotation of the housing relative to the connecting member.

Razor blade system

Shaving aid strip for razor cartridge

A shaving system includes a replaceable shaving cartridge and a shaving razor handle. The replaceable shaving cartridge has a housing carrying blades, a guard, a cap, and a camming surface. The cartridge includes an interconnect member having a pivotal support structure that pivotally supports the housing and a base structure adapted to be removably and fixedly attached to the handle. A shaving razor handle has an elongated hand gripping structure and a cartridge support structure extending from an end of the hand gripping structure. The cartridge support structure has an extension with outer side surfaces that mate with inwardly directed surfaces of a recess on the cartridge and an end surface with an opening. The extension has an asymmetrical shape to ensure proper orientation. A spring-biased plunger is retained in the cartridge support structure and extends through the opening of the cartridge support structure.

Shaving system and method

A razor cartridge comprising a housing having an elongated blade receiving region defined between two side walls spaced from each other along parallel first axes and between a guard and a cap spaced from each other along parallel second axes that are transverse to the first axes, the housing also having blade-receiving slots in the side walls that face each other and extend along third axes that are transverse to both the first and second axes, and elongated blade members having blades with cutting edges that are parallel to the first axes and bent supports that extend downward from the blades and have support ends at the ends of the blade members that are mounted for movement in the slots along the third axes, the slots being defined by front stop portions and back stop portions of the housing on opposite sides of respective first and third axes, the front stop portions being located underneath the blades, the back stop portions being located along respective first axes outside of the front stop portions in a direction away from the blade receiving region.

Razor cartridge with movable blades

A replaceable razor blade cartridge including a blade unit, and cartridge connecting structure for connecting the blade unit to handle connecting structure of a handle, the cartridge connecting structure having inwardly directed surfaces for mating with outwardly directed surfaces on the handle connecting structure, the blade unit being pivotally connected to the cartridge connecting structure, the cartridge connecting structure including a latching member that is movable to release the cartridge from the handle connecting structure prior to retraction of the cartridge connecting structure from the handle connecting structure.

Shaving system including handle and replaceable cartridges

A cartridge-connecting subassembly for a shaving razor handle including a cartridge connecting structure, a handle connecting structure, and a movable component within the cartridge connecting structure that interacts with a replaceable cartridge when it is connected. The cartridge connecting structure and handle connecting structure have outer side surfaces that mate with inwardly directed surfaces of the cartridge and handle so that the subassembly is substantially covered when it is mounted in the handle and a cartridge is connected. The subassembly has an assembly opening for receiving the movable component during assembly, a cartridge interaction opening through which the component is movable for interaction with the cartridge, and blocking structure that retains the movable component in the subassembly. The movable component is an ejector structure that is separate from the cartridge connecting structure. The subassembly is connected to the handle by staking. The handle has gripping pads with an elastomeric outer layer and an nonelastomeric support layer thereunder.
