Embodiments described herein relate to a safety razor and to a handle for a safety razor.
Safety razors are typically composed of a blade unit (or cartridge) connected, either detachably or fixedly (permanently fixed or integrated), to a handle. A safety razor with a detachable and disposable cartridge is known as a safety razor system. Cartridges are known which have one or more parallel blades perpendicular to the shaving direction and thus to the handle, each defining a cutting edge, with cartridge elements positioned in front of and behind (rear of) the cutting edge(s) (referred to as a “guard” and a “cap”, respectively) in a shaving direction. A shaving aid, such as a thin lubricating strip, or lubrapad is often incorporated into one or both of these cartridge elements to improve shaving performance and lubricating treatment of the user'"'"'s skin. Typically, the handle is elongate extending essentially in the direction of shaving. It would be desirable to provide an alternative handle design.
Embodiments of the invention provide a safety razor (or safety razor system, in which the cartridge is always detachable) comprising: a handle body with a substantially flat end surface and a side surface; and a cartridge attached to the side surface, wherein: when the flat end surface is in contact with a horizontal plane, the safety razor is in a stable position of rest, the flat end surface forming the safety razor'"'"'s only region of contact with the plane and elevating the cartridge above the plane.
The flat end surface allows the handle to stand on a horizontal plane, such as a basin edge or shelf with the blades and any lubrapad of an attached cartridge suspended above the surface and no other point of contact between the safety razor and the horizontal plane. This can help prevent blade corrosion and adhesion of the lubrapad to the surface.
The term “flat” is used herein to describe a surface which is completely or substantially flat and which thus may include some portions which are not flat (and thus some portions which are not in contact with the horizontal plane). For example, the surface may include patterns, a logo, an opening or writing recessed into the flat surface, some surface texturing or curvature or the like. However, the surface may be substantially unbroken. Preferably over 80%, or more preferably over 90% of the surface is in contact with the horizontal plane.
The term “stable position of rest” indicates that the safety razor will stay in the upright position on its flat end surface with the cartridge elevated without any external assistance/force.
In one embodiment, an overall handle body shape is bulbous in two orthogonal directions. Thus an outline/silhouette of the handle body in both directions may be generally fat and round (over the whole extent of the handle body).
The flat end surface and the “chunky” bulbous shapes of the handle allow not just a particularly stable position with the flat end surface on a level counter, but also a particularly flexible ergonomic handling, giving many varied gripping positions for the human hand and easy twisting of the handle within the grip to reach different angles.
The side surface may be a curved surface (made up of a single surface on several curved surface portions) adjacent to the flat end surface. This can give a good handling feel, with a flat face and possibly also an edge between the flat face and a curved face providing a tangible spatial reference to the user in combination with an easy-grip curved surface.
The handle body may comprise an opposite further end surface, giving even better handling feel. The further end surface may be rounded (concave or convex) and is preferably an opposite flat surface (opposite to the end surface). The side surface may be a single continuous curved side surface (or in fact the rest of the handle body including the opposite end may form a single continuous curved surface). This curved side surface, or a plurality of curved side surface portions, may provide the handle body with a cross section that increases away from the flat end surfaces towards the centre of the body, forming the bulbous shape mentioned above.
The flat end surfaces may be parallel, providing a symmetry which gives the user a better tactile impression of the overall handle, for improved shaving experience. One or both of the flat end surface(s) may be circular or elliptical, for example.
In use, the safety razor is pulled backwards across the skin in the shaving direction. The flat end surface may be in front of the blades in the shaving direction (to the rear of the razor if the cartridge is seen as the front), and the further flat end surface may be behind the blades in the shaving direction (to the front of the razor).
Any connection between the cartridge and the handle body may be used. For example, a part of the cartridge may simply fit into a recess in the handle body, or structure which is part of the handle may be provided outside or inside the handle body for attachment of the cartridge. This structure may be on (and/or inside) the side surface, or on (and/or inside) the flat end surface and the side surface.
In one embodiment, the safety razor further comprises a stem connecting the cartridge and the handle body, which extends from the side surface preferably parallel to the substantially flat end surface and connects the cartridge to the handle body.
In a safety razor system, a part or all of the stem may be permanently attached to the handle body and a part or all of the stem may be permanently attached to the cartridge. For example, there may be a handle stem and a cartridge stem which are releasably attached together. The handle stem may extend into the cartridge stem when the two are attached or vice versa to provide a connection.
The flat end surface may be of a size which gives good stability to the safety razor when resting on a plane. Thus it may have an area which is larger than the footprint of the cartridge on the skin surface, or preferably an area which is twice or more this size.
The handle body is not elongate. For example, the largest extent of the handle body (measured in any direction) may be up to twice the smallest dimension of the flat end surface. In one embodiment, the distance between two parallel flat end surfaces is equal to or smaller than the diameter (or smallest dimension) of one or both flat end surfaces.
In one preferred construction, the centre of mass of the handle and cartridge is above and vertically within the footprint of the flat end surface on the horizontal plane, and the handle body overhangs the flat end surface to one side when the razor is stably positioned on the flat end surface. This overhang side is preferably the side on which the cartridge is mounted. The cartridge may be mounted closer to the further flat end surface than to the flat end surface (i.e. closer to the front of the razor than to the rear in use, and closer to the top of the razor when stably positioned on the plane). Various different angles of overhang are possible.
If the stem projects from the side surface and preferably parallel to the end surface, then a slanted/overhang design of the safety razor (with the end surface(s) extending at a slant (non-perpendicular angle) to the average direction of the side surface between the centre of the flat end surface and centre of the further end surface) allows the handle body to sit with the flat end surface at the back of the user'"'"'s hand grip, on or towards the palm of the hand, with the user'"'"'s fingers positioned on the opposite end surface and side surface. In this position the end surfaces slope up and back towards the user'"'"'s hand, allowing a better view of the cartridge.
The stability of the safety razor on the horizontal plane can be assured in any suitable way. The material of the handle body on the same side of the centre of mass as the overhang may be less dense than the material of the handle body to the other side of the centre of mass from the overhang. For example, there may be a hollowed portion extending in the overhang side, or a lower density material.
Equally, the flat end surface may be provided with an anti-tilting lip on the same side as the overhang. The anti-tilting lip may extend from the end surface on the overhang side.
Any suitable means may be provided to aid stability of the safety razor. For example, the flat end surface may be provided with a suction feature, such as an air opening into a hollow part in a flexible handle body to help retention of contact between the flat end surface and the horizontal plane.
Equally, the flat end surface may be provided with a recess or other interface allowing attachment to another part, such as packaging or a travelling case, or suspension from a hook (which could be provided separately) on a wall or other vertical surface (or the same air opening could be usable for both purposes).
The handle body may be made of a single part and material (excluding any minor additions of logos etc). In one embodiment it is made of two or more parts, such as a core and an external layer, or two opposite halves, which are fabricated individually, and then connected. The stem may also be connected to form the full body at the same stage.
The stem and part of the handle body may fabricated from one part, for example to include a cartridge release mechanism and the rest of the handle body may fabricated from another part, possibly a translucent part.
In some embodiments, the handle body includes an insert inside a translucent material of the handle body. This insert may be used to permanently and attractively display a logo.
The handle body may have any suitable construction. The handle body may comprises a single material or may comprise a core material and an outer material. Inserts may be made in the same material or one or more different materials. In one embodiment the handle body is solid or contains a hard core or hard hollow core. This may allow the use of a softer material for the rest of the body.
In one embodiment, the handle body comprises a single moulded translucent or transparent body (forming a core or hollow core, an outer layer or the full body) of elastomeric material such as silicone, TPU (thermoplastic polyurethane), TPE (thermoplastic elastomer) PETG (Polyethylene Terephthalate Glycol), TPS or rubber (such as liquid silicone rubber or compression silicone rubber) for example having a Shore A hardness of around 5 to 80, preferably a squeezable 20 Shore A under the ASTM D2240-00 testing standard.
As used herein, TPEs are thermoplastic elastomers, for example thermoplastic elastomers selected from the group of styrenic block copolymers (TPE-s including TPE SBS and the hydrogenated version of TPE-SEBS; e.g. Thermoplast K, Thermolast M, Sofprene, or Laprene), thermoplastic olefins (TPE-o; e.g. For-Tec E), elastomeric alloys (TPE-v or TPV; e.g. Thermolast A, Thermolast V, Hipex, Forprene, Termoton-V, or Vegaprene), thermoplastic polyurethanes (TPU; e.g. Copec), thermoplastic copolyesters (TPE-E), thermoplastic polyamides and mixtures thereof.
As used herein, silicones (or polysiloxanes) are polymers that include any inert, synthetic compound made up of repeating units of siloxane.
These materials give a superior tactile feeling with a material that is soft and yet strong due to the shape of the handle. Moreover, the body being translucent or transparent allows the user to gain a better feel of the positioning of the handle (and thus of the attached blade unit) with respect to the hand and to the skin to be shaved.
The stem/attachment to the cartridge may be fabricated separately, from PPA Polyphthalamide)(/PPS (Polyphenylene sulphide)/LCP (Liquid Crystal Polymer) or ABS (Acrylonitrile Butadiene Styrene). The material may have a glass filling of 0% up to 40%, or 10% to 30%, preferably around 20%.
The materials and/or fabrication process may be chosen in such a way that the insert and core material will chemically bond with the handle material.
In one embodiment, the handle body is made entirely from a soft transparent silicon and the insert forming the stem is made from PPA (Polyphthalamide) with 20% glass filling. In another embodiment, the handle body is made entirely from a soft transparent TPE (thermoplastic elastomer) and the insert is made from PP (polypropylene) with 20% glass filling. In another embodiment, the handle body external portion is made from a soft transparent TPE (thermoplastic elastomer) and a handle body core and the stem are formed together from a thermoplastic.
A further embodiment relates to the handle when the cartridge is not attached. According to this further embodiment there is provided a safety razor handle comprising: a handle body with a substantially flat end surface and a side surface; and a cartridge attachment on the side surface, wherein: when the flat end surface is in contact with a horizontal plane, the safety razor is in a stable position of rest, the flat end surface forming the safety razor'"'"'s only region of contact with the plane and elevating the cartridge attachment above the plane.
According to the further embodiment, not only is the cartridge attachment elevated, so that it allows the handle to be resting in a stable position and the user to easily exchange a cartridge, but any attached cartridge is also elevated.
As mentioned previously in the description of the safety razor as a whole, the cartridge (and cartridge attachment or stem) may be on the side surface positioned towards the further end surface and thus towards the top of the razor when the razor rests on its end surface.
The above indicated aspects and embodiments may be combined with each other to achieve the advantageous effects as described above. Further embodiments, features, and advantages of the invention, as well as the structure and operation of the various embodiments of the invention are described in detail below with reference to the accompanying drawings.
The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention.
Reference will now be made to
The following detailed description refers to the accompanying drawings that illustrate examples and embodiments consistent with this invention. Other embodiments are possible, and modifications can be made to the embodiments within the spirit and scope of the invention. Therefore, the detailed description is not meant to limit the invention.
The term “underneath” is used to describe features of the handle, cartridge or a lubrapad that are positioned on the skin-contacting side of the cartridge or lubrapad (i.e., on a shaving-side or underneath of the handle, cartridge or lubrapad) in use, and the term “top” is used to describe features of the handle, cartridge or lubrapad that are positioned on a side opposite the skin-contacting side of the cartridge or lubrapad in use (i.e., on a user side or on top of the cartridge or lubrapad). The terms “front”, “rear”, and “side(s)” are used herein with reference to the shaving direction, i.e., the direction in which the cartridge and lubrapad are intended to be moved during shaving. In particular, the term “front” means facing in the shaving direction, “rear” means facing in the opposite direction to the shaving direction, and “side(s)” mean to either side in the shaving direction. In general, the cartridge is positioned at the front of the razor in use and the razor is pulled backwards across the skin (with the cartridge last).
Reference will now be made to
The handle body has a flat end surface 52 on which it can rest stably upright on a (substantially) horizontal surface, as shown in
When the razor is in use, the flat end surface forms the rear surface of the razor, as shown in
Opposite to the flat end surface is a further flat end surface 51. This is a front surface portion when the razor is in use, as shown in
These two opposite surfaces are parallel, and are separated by a single continuous side surface 56. As can be seen clearly from
The side surface of the handle body 56 has a curved underneath portion 53, a curved top portion 54 and curved lateral portions 55 in use as shown in
As shown best in
The handle body is made entirely from a translucent silicone or TPE-SEBS in this embodiment, as can be seen better in
The handle body may be formed by either LSR or injection or compression moulding. The full razor may weigh around 40 to 60 grams, preferably around 55 grams and the handle body may have a Shore A hardness of approximately 10 to 50, preferably 15 to 40 or around 20, to give a squeezable feel and pleasurable tactile sensation when gripped by the user. It may include a logo on the front surface (the further end surface which is on the top when the razor is in the upright position).
The stem may be fixedly connected to the handle body, such as by chemical connection.
In other embodiments, the handle body may have a hollow or solid insert (such as a core) of another material. If there is a hollow insert, it may store a fluid, such as a shaving preparation. In this case, the stem between the cartridge and handle body may include a fluid passage for a shaving preparation dispensed from within the body and the body may include a dispensing aperture.
The cartridge of these figures may include a lubricating strip or wider lubrapad 12 (not shown) as an additional or integral part of the cartridge, for example with a single frame both surrounding the blades and providing a back support for the lubrapad. The end surface has been shown and described as flat, but may alternatively be curved or uneven, if there is no requirement for the razor to be stable in an upright position.
Some advantageous dimensions of the safety razor which give good manoeuvrability in the human hand are shown in
The maximum length of the handle body parallel to the skin surface in use (with the end surface at 45° to the skin surface) is from 40 to 80 mm, preferably between 56 and 64 mm, for example 61 mm. This is measured from the foremost extent of the front (the lowest portion of the front or further end surface) to the rearmost extent of the rear (the highest portion of the rear or end surface which rests on the horizontal plane when the razor is upright). The maximum height of the handle body in use is between 25 and 55 mm, preferably between 36 and 41 mm, for example 39 mm.
The distance between the end surfaces is between 25 and 45 mm, preferably between 31 and 36 mm, for example 35 mm. The handle stem (or other interface between the handle and cartridge) starts at 3 to 10, preferably 5 to 6 mm along the underneath portion of the side surface in use from the front surface. The maximum width of the handle body measured parallel to the end surfaces is between 35 and 60 mm, preferably between 42 and 48 mm, for example 46 mm.
If the cartridge is flat on the skin in use, the end surfaces extend at between 35 to 55, preferably at 45 degrees to the skin surface.
The cartridge footprint may have a length of around 25-60 mm in the blade direction, preferably around 40-50 mm and a depth orthogonal to the blade direction from the front to the rear of the cartridge of around 10-30 mm, preferably 15-23 mm. Whilst the cartridge size may have a natural maximum linked to its function, the handle body and in particular the handle body extent in the blade direction is not similarly limited.
In an alternative definition which can be applied to these figures and the earlier and later figures, some embodiments of the invention provide a safety razor handle comprising: an underneath surface portion 53 facing the skin of the user in use and comprising an attachment means (such as a stem) for attachment to a blade unit; a front surface portion 51 facing in the opposite direction from the shaving direction in use; a rear surface portion 52 facing in the shaving direction in use; a top surface portion 54 and lateral surface portions 55, one directed to either side of the blade length in use; wherein the top surface portion, underneath surface portion and side surface portions together form a continuous smooth surface which is a substantially cylindrical or substantially ellipsoid or substantially partially spherical surface; and wherein: the distance between the front surface portion and rear surface portion is between one third and three times, preferably between a half and twice, the largest dimension of the largest cross section through the continuous smooth surface.
The term substantially cylindrical or substantially ellipsoid or substantially partially spherical surface is used to describe a shape which is close to cylindrical or ellipsoid or partially spherical form, for example with a 10% deviation from one of those forms. In one measure, a section (or all sections) taken vertically through the continuous smooth surface (for example in a direction parallel to the blade length) overlaps with a circle or ellipse drawn to just cover the whole section with the areas of the circle or ellipse which are not covered by the section being up to one tenth of the area of the section.
The front and rear surface portions may be flat or concave. The front surface may extend to the guard side of the attachment to the blade unit, and may conveniently be provided with a logo and/or instructions. It may extend substantially parallel to the rear surface portion and preferably substantially parallel to a main direction (in terms of longest extent) of the stem.
In another embodiment the body is hollow and contains a shaving preparation, which, for example, can be squeezed out by the user via the attachment means to the blade unit. Thus the shaving preparation (which may contain lubricating and/or hair conditioner and/or moisturiser) may pass through the recess, for example within a part of the blade unit which is housed inside the recess.
In one razor embodiment, the attachment means for attachment to the blade unit and corresponding means on the blade unit allow relative movement, such as pivoting movement, between the handle and the blade unit. For example the connection between the corresponding means and attachment means may have some play, or one or both of the attachment means or corresponding means may be flexible.
In one embodiment the corresponding means is a stem extending from the blade unit to the handle. The stem may fit into the recess, permanently or detachably.
In a further embodiment, the razor comprises a hard shell extending from the stem and forming part of the handle. The hard shell may give additional support to the body and a enable an enhanced connection to the blade unit.
In one embodiment either the stem or the shell is provided with a spigot (outlet for fluid connection from the body) which extends into the handle, to transport shaving preparation.
In one embodiment the shell forms the rear surface portion and part of the underneath and side surface portions of the handle. In this case, the shell may fit over the elastomeric material (such as TPE, rubber or silicone) body described previously. It may fit into receded surface portions of the body, so that the combination of the shell and the body provides a smooth external surface.
In one embodiment the safety razor further comprises a lubrapad. For example, a lubrapad body may be provided adjacent to the blade unit, and extend along a guard of the blade unit and in front of the guard in use. The lubrapad body may have a greatest width and/or depth in the blade direction at the guard, the body width and/or depth reducing in a smooth convex curve away from the guard to a curved front portion of the body.
In one embodiment the lubrapad body and cartridge are provided separately and comprise attachment means to attach them together whilst allowing relative movement, such as flexible projections from a front surface of the guard, which are to be housed in recesses in a surface portion of the lubrapad body which is directly facing the guard front surface.
In a further definition of the handle, invention embodiments provide a safety razor handle comprising a moulded translucent or transparent body of elastomeric material such as TPE, silicone or rubber having a Shore A hardness of 5 to 65 or preferably 10 to 50; wherein the body has a shape which is rounded and chunky (or bulbous), extending with perpendicular length I, width w and height h, wherein none of the maximum length, width and height of the body is more than 2, 3 or 4 times the size of the maximum in the other two dimensions.
For example, the height may be the largest vertical cross section through the side smooth surface previously defined, the width may be the largest horizontal cross section through the side surface and the length may be the horizontal distance (parallel with the shaving plane) between the end surfaces.
Any of the previous features of the handle and safety razor (and safety razor system) may be applied to these embodiments.
The smooth/continuous reduction of the width and depth of this lubrapad and the convex form of the gliding surface allows improved gliding across the skin of a user, with provision of the most lubrication closest to the blades.
Separating the cartridge and lubrapad, so that they can move independently from one another, allows the cutting and lubricating functions to be separated, and that allows optimization of the cartridge and lubrapad design to conform to, or follow, the contours of a user'"'"'s skin. The term ‘lubrapad’ generally refers to a solid shaving aid that has lubricating properties. The lubrapad can, of course, have other properties considered beneficial during shaving such as, for example, moisturizing properties. The lubrapad can be provided ‘bare’ in that it is not contained or surrounded by any manner of housing, base, or holder. Furthermore, the lubrapad body can consist entirely of solid lubricating material or the lubricating material can form part of the body, such as a layer on the body.
The composition of the lubrapads described herein can include a gliding agent. Materials which may be selected as the gliding agent are: PEG-400/1,4-Butanediol/SMDI Copolymer, PEG-115M, PEG 45M, and PEG-5M, or a combination thereof. The composition of the lubrapad can include an antioxidant agent, for example Tocopherol. The composition of the lubrapad can include an anti-inflammatory agent, for example aloe barbadensis leaf juice. The composition of the lubrapad can include a backbone structure. Materials which may be selected as the backbone structure are: styrenic block copolymers and polystyrene, or a combination thereof.
The handle 50 includes a hard curved shell 80 and the soft/medium soft silicone/TPE-SEBS body 70. The hard shell is provided at the front of the razor (closest to the cap) and forms the slanted front surface portion. It also curves to form part of the underneath surface portion. Where it joins the soft body, the body is shaped with receded portions 82 to give a smooth continuous external curved surface.
The shell is formed integrally with the stem 61 of the cartridge and the cartridge, but is detachable from the body 70.
The handle bodies in
An increased specific weight to the rear (non-overhang side) in the upright position may be achieved by holding liquid such as water or shaving/cleaning emulsions within the handle body.
Due to the tilted design of the handle (see
The standing functionality is improved or safeguarded by adding a suction feature 57 on the right side of the tipping line (see example B). This suction feature comprises an air opening and an elastic seal rim located around the opening in a hollow (or partially hollow) squeezable elastic handle (to create an under pressure). The suction feature might also be used for other reasons, such as hanging from a vertical wall, or refilling the handle by sucking up shaving/cleaning liquids or foam. It could also feature a valve to prevent leakage in case a refilling functionality is used.
This interfacing feature could also be a means to mechanically connect and seal the handle to a refill application (for instance a squeeze bottle) enabling an easy refill with shaving or cleaning liquid/foam inside of the handle. In this case a further opening in the handle might be required to allow the passage of air.
The handle body can be made of one or multiple parts or part combinations and/or have different materials and/or material combinations. The different parts and materials could introduced from a design perspective and/or have economic and/or functional reasons. The handle may be fabricated from the following materials: thermoplastic elastomers/thermoplastics/thermoset/silicones/metals/ceramics/natural materials (like wood or stone)/glass or composites. These materials can have different colouring, be opaque, translucent or transparent
The outside of the handle body could be separately fabricated from lacquers or coated with different materials to improve design or functionality.
The handle can be manufactured in different ways. Plastics can be fabricated by casting/injection moulding/compression moulding/milling I stamping/etc. The handle body can be manufactured all at once in one piece (as shown in
In each case, the stem of the handle or neck housing for connection to the cartridge is shown as a separate piece. However, the stem may be of the same material as and/or integrally formed with either of part 1 and part 2. In one advantageously simple and elegant construction, the core and stem (for example as shown in
In each case, the outer handle body is translucent and a cylindrical insert (for example of a different material) is used to display a logo. The insert may be of a depth which is much smaller than its diameter (a coin-shaped insert) or it may be of a depth which is equal or greater than the diameter. The logo may be a physical part of the insert and be protruded or recessed. Additionally or alternatively, it may be printed or lacquered or given a surface texture or finish which distinguishes it from the insert.
