The present invention is directed to a shaving assembly and is particularly directed to a wet shaving assembly capable of simultaneously lubricating and shaving a shaving surface in a single stroke.
Shaving body hair typically requires at least five distinct steps: (1) wetting a skin surface, (2) preparing and/or dispensing a skin preparation (e.g., shaving cream), (3) applying the skin preparation to the shaving surface, (4) shaving the skin surface with a blade, and (5) washing away excess shaving preparation remaining on the skin surface. The above-mentioned steps are relatively complex and require a significant amount of time.
There have been a wide variety of efforts directed to combining two or more of the above-listed steps. For example, U.S. Pat. No. 4,712,300 discloses a razor blade capable of moisturizing and shaving the skin in a single step. The razor blade holder includes a block of sponge-like material having a razor blade assembly implanted therein, with the cutting edges of the blades arranged at or slightly below the surface of the sponge-like block. When wet, the sponge-like block may be pressed lightly on the skin surface and moved in a direction for shaving the skin.
U.S. Pat. No. 4,074,429 discloses a combined assembly for applying lather and moisture to a shaving surface in advance of a razor blade so that the shaving operation can be conducted in a single stroke. This is accomplished by attaching a lathering device, such as a soap cake, immediately in front of the blade of a razor. During a shaving operation, the razor and lathering device are immersed in water and the razor is drawn across a user's skin in an ordinary manner. The position of the lathering device on the razor is such that the soap cake contacts the user's face immediately in advance of the razor blade and thus provides a lubrication immediately before shaving. However, the use of the lather-applying assembly requires constant adjustment of the soap cake so that the lubricating substance is properly applied to the shaving surface.
U.S. Pat. No. 4,562,644 discloses a lubricant-applying safety razor including a lubricating member provided in front of a cutting edge of a blade. The lubricating member is an elongated cylindrical roll formed of lubricating compounds and extending substantially across the width of the cutting blade. When the razor is moved along a user's skin in a shaving motion, the lubricating member engages the skin of the user to apply a lubricating film to the skin.
U.S. Pat. No. 3,895,437 discloses a shaving assembly including a sponge-like element secured to a razor in a position that immediately precedes the advance of the blade. The sponge-like element is maintained in a saturated condition so that upon contacting shaving preparation applied to a user's face, the shaving preparation is moisturized by the sponge.
U.S. Pat. No. 4,944,090 discloses a razor including a soluble body carried by a razor cartridge. The soluble body is movable relative to the razor cartridge and is biased through an opening in the razor cartridge by a spring. The soluble body does not completely surround the razor. As a result, the razor may lubricate the skin in only one axial direction.
U.S. Pat. No. 5,141,349 discloses an apparatus for lubricating the blade of a razor by applying a liquid lubricant and solubilizer mixture via an aerosol system. The lubricant is applied directly to the razor blade immediately prior to shaving so that shaving can be performed without first applying a shaving preparation directly to the area to be shaved.
U.S. Pat. No. 5,121,541 discloses an electric razor which houses a misting mechanism for misting a lubricating agent, such as water, cologne or beard softener onto a user's skin while shaving. The misting mechanism includes a mist conduit, misting container and an ultrasonic vibrator. The ultrasonic vibrator is activated by the same power source as the electric razor. A protective screen overlies the mist conduit to prevent whiskers from contaminating the misting mechanism.
To some extent, the above-mentioned patents have simplified and/or improved the shaving process. However, the shaving devices disclosed in these patents are incapable of operating effectively in certain unique shaving environments, such as when a user attempts to shave while taking a shower. In addition, the shaving devices are able to lubricate and shave in only one direction.
There are a number of unique problems associated with shaving in a shower. First, the shaving preparation, such as shaving cream, is frequently washed away from the shaving surface before the razor touches the skin. As a result, there is typically little or no lubricant covering the skin or shaving surface during shaving. This makes it difficult, if not impossible, to take advantage of the lubricating properties of a shaving preparation and generally results in an uncomfortable shaving experience. Moreover, individuals who shave while in a shower must often assume awkward and unsafe positions in order to prevent water from washing away the shaving preparation. In addition, shaving in the shower is a rather complex process that requires a shaver to 1) place the razor in a stable location within the shower; 2) apply a shaving preparation to a skin surface; and 3) re-grasp the razor for shaving the skin. The chance that a user will drop the razor during this complex process in significant. In addition, the user must insure that the blade is drawn in only one direction over the skin surface to avoid nicks and cuts.
In response to the problems associated with shaving in a shower, commonly assigned U.S. patent application Ser. No. 09/505,408, filed Feb. 16, 2000, entitled “Wet Shaving Assembly,” discloses a shaving assembly for simultaneously applying a shaving preparation and removing hair in a single step. The shaving assembly includes a base having an upper end, a lower end and a hollow space between the upper and lower ends, whereby the hollow space defines an opening at the upper end of the base. The shaving assembly also includes a receiver for a razor, such as a cartridge receiver for a razor blade cartridge, that is connected with the base and that is disposed at the opening at the upper end of the base. The cartridge receiver has a perimeter and the opening at the upper end of the base completely surrounds the perimeter of the cartridge receiver. The hollow space of the base is adapted for containing a substantially solid shaving preparation, such as a soap cake, or a body wash and may be combined with skin beneficial ingredients and/or scent.
Thus, there is a need for a shaving assembly that allows for efficient and safe shaving in a wet environment, such as a shower. There is also a need for a shaving assembly that incorporates a fluid shaving preparation with a razor in such a way as to maximize skin lubrication during hair removal. Such a wet razor system should also allow for simultaneous application of a shaving preparation and hair removal, thereby reducing the amount of time spent in the shower.
In accordance with certain preferred embodiments of the present invention, a lubricating shaving assembly includes a body that may be grasped by a human hand. The body is preferably made of a polymer material such as plastic, a metal, or a combination of a polymer and metal. The body preferably has an upper end, a lower end, and one or more side walls extending between the upper and lower ends. The upper end of the body preferably includes a razor cartridge receiving area that is adapted for having one or more razor cartridges attached thereto. The one or more razor cartridges may be pivotally attached to the razor cartridge receiving area. The one or more razor cartridges may also be flexibly attached to the razor cartridge receiving area so that the razor cartridges may simultaneously pivot, swivel or move torsionally relative to the cartridge receiving area. In certain preferred embodiments, the shaving assembly includes a dispenser portion that stores the shaving preparation and a detachable cap that secures the one or more razor cartridges. The cap may be removed from the dispenser portion so that either the cap or the dispenser portion may be disposed of and replaced with a new cap and/or dispenser.
The body preferably includes a storage reservoir that is adapted for holding and dispensing a fluid shaving preparation such as a gel, semi-solid material such as a gel, cream, oil, foam or lotion. Before the shaving assembly is operated, a mass of fluid shaving preparation is deposited in the reservoir. The mass of shaving preparation may be deposited within the reservoir during the initial manufacture of the assembly, or the reservoir may be refilled with a refill purchased by a retail consumer. The storage reservoir is desirably substantially enclosed by the upper and lower ends of the body, as well as by the one or more side walls of the body. The upper end of the body may also have a plurality of openings adjacent the razor cartridge receiving area. The plurality of openings may surround the razor cartridge receiving area and may also be provided within the razor cartridge receiving area. The plurality of openings are preferably in communication with the storage reservoir.
The body also preferably includes a selectively movable pedestal having a top surface and a bottom surface. The top surface of the pedestal may be substantially flat. The pedestal is desirably disposed within the storage reservoir of the body and has an outer perimeter that closely engages the interior surface of the sidewalls extending between the upper and lower ends of the assembly. The pedestal is preferably selectively movable between the lower and upper ends of the body for dispensing the fluid shaving preparation stored in the reservoir through the plurality of openings at the upper end of the body.
In certain preferred embodiments, the upper end of the body or cap may include one or more retaining tabs that are attachable to the upper end of the body for securing one or more razor cartridges within the razor cartridge receiving area. The one or more retaining tabs may be permanently attached to the upper end of the body, such as by being hingedly attached to the upper end of the body by flexible hinges. The retaining tabs preferably engage one or more ends of the razor cartridges for securing the razor cartridges within the cartridge receiving area. The secured razor cartridges are preferably capable of pivoting, swiveling, and/or moving torsionally within the razor cartridge receiving area.
Each razor cartridge preferably includes one or more cutting blades having a longitudinal axis. The longitudinal axis of each razor cartridge preferably extends in a direction that is substantially parallel to the longitudinal axes of the cutting blades attached thereto. In certain embodiments, two razor cartridges are attached to the razor cartridge receiving area of the body so that the one or more cutting blades of the two razor cartridges face one another. The razor cartridges may also include one or more wires, molded elements, or die cut elements that extend in directions substantially transverse to the longitudinal axis of the one or more cutting blades. The one or more wires, molded elements or die cut elements preferably overlie the one or more cutting blades. Each razor cartridge may also include a mesh overlying the one or more cutting blades of the razor cartridge. In yet other preferred embodiments, the razor cartridge may include one or more razor blades in the form of a metal foil having a number of holes therein, whereby each hole has a peripheral portion having one or more cutting edges. Such razor cartridges are disclosed in commonly assigned U.S. Pat. No. 4,438,068, the disclosure of which is hereby incorporated by reference herein.
As mentioned above, the movable pedestal preferably includes an outer perimeter that closely engages the interior side walls of the body so as to form a fluid-tight seal therebetween. As the pedestal moves in an upward direction, the mass of fluid shaving preparation is forced toward the plurality of openings at the upper end of the body. Thus, the upwardly moving pedestal urges and/or forces the shaving preparation through the plurality of holes. Because the plurality of holes are adjacent the razor cartridge receiving area, the shaving preparation will be dispensed around the one or more razor cartridges attached to the body.
A broad array of elements may be used for moving the pedestal toward the upper end of the body. A ratcheting mechanism may be connected to the body and the pedestal for selectively moving the pedestal. At least a portion of the ratcheting mechanism is preferably accessible at the exterior surface of the body. The ratcheting mechanism may extend through an opening in the one or more side walls of the body. The ratcheting mechanism may also include a rotatable knob, a lever or a depressible button. The ratcheting element preferably makes a clicking sound or produces a vibration so that a user can sense that an incremental advancement of the pedestal has occurred. In certain embodiments, lower end of the pedestal may also include an opening extending therethrough having internal threads that are adapted for receiving at least a portion of the adjustable element. The adjustable element may include a rotatable shaft having a first end in contact with the pedestal and a second end that extends through the opening at the lower end of the body. The shaft may have external threads extending between the first and second ends thereof for engaging the internal threads of the opening of the pedestal. A knob may be attached to the lower end of the shaft. The knob may be rotated which, in turn, rotates the shaft. As the shaft rotates, the external threads of the shaft engage the internal threads of the opening of the pedestal for moving the pedestal toward the upper end of the body.
In certain preferred embodiments, one or more parts of the shaving assembly may be disassembled and/or detached from one another so that one of the parts may be replaced. In one preferred embodiment, one or more worn or dull razor cartridges may be detached from the assembly and replaced with new razor cartridges. In other embodiments, the upper end of the body or cap may be detached from the lower end or dispenser portion of the shaving assembly. The cap may have one or more razor cartridges permanently secured thereto. In this embodiment, the cap may be selectively detached from the lower body and replaced with a replacement cap having fresh razor cartridges secured thereto. The lower end of dispenser portion of the shaving assembly may also be replaced when the reservoir for the shaving preparation is emptied.
In still other preferred embodiments, a shaving assembly preferably comprises a handle having an upper end, a lower end and a substantially enclosed storage reservoir between the upper and lowers ends, the storage reservoir being adapted for holding a fluid shaving preparation. The upper end of the handle desirably has a razor cartridge receiving area adapted for having one or more razor cartridges attached thereto. The upper end of the handle preferably includes a plurality of openings adjacent the razor cartridge receiving area and in communication with the storage reservoir. A pedestal is preferably disposed within the storage reservoir. The pedestal is preferably movable toward the upper end of the handle for urging the fluid shaving preparation through the plurality of openings. The shaving assembly may also include one or more razor cartridges attached to the razor cartridge receiving area at the upper end of the handle. As the pedestal moves toward the upper end of the handle, the shaving preparation urged through the plurality of holes is dispensed about and adjacent the one or more razor cartridges. The movable pedestal may be connected to the handle by a ratcheting mechanism accessible at an exterior surface of the handle. The ratcheting mechanism may be actuated for moving the pedestal toward the upper end of the handle for dispensing shaving preparation. In other embodiments, an adjustable element including a knob may be in contact with the handle and the movable pedestal for selectively moving the pedestal toward the upper end of the handle. The adjustable element may include a rotatable shaft having a first end in contact with the pedestal and a second end that extends toward the lower end of said handle. The rotatable knob may be secured to the lower end of the shaft, whereby the knob may be rotated for moving the pedestal toward the upper end of the handle so as to dispense a portion of the fluid shaving preparation.
The upper end 23 of cap 28 also preferably includes a plurality of apertures 46 that surround at least a portion of the perimeter of the razor cartridge receiving area 32. The cap may also include central apertures 48 provided within the razor cartridge receiving area 32. The peripheral apertures 46 surrounding the razor cartridge receiving area 32, and the central apertures 48 provided within the razor cartridge receiving area 32 are desirably in communication with an underside (not shown) of the cap. As will be described in more detail below, the apertures 46, 48 provide a path for a lubricating shaving preparation to be dispensed within and around the razor cartridge receiving area 32. As a result, the shaving preparation may be provided about the razor cartridges during a shaving operation.
