HAIR REMOVAL DEVICE AND ACCESSORY THEREOFFIELD OF THE INVENTION
[0001] The present invention relates to the field of handles for hair removal devices, particularly to a handle for a device such as a wet razor or an electric shaver that comprises one or more glow-in-the-dark regions to enhance visibility and safety. The invention also relates to accessories for such devices.BACKGROUND OF THE INVENTION
[0002] Hair removal devices, such as razors and electric shavers, are common personal care items. These devices typically comprise a handle for gripping and a head containing the cutting elements, such as razor blades or foils and cutters. A significant safety issue arises when a user reaches for such a device in low-light conditions, for example in a travel bag, a dimly lit bathroom, or at home at night without turning on the lights. In such situations, it can be difficult to distinguish the handle end from the potentially hazardous head end, posing a risk of accidental cuts. It is also a helpful guidance for handicapped people to orient where to find what part of the razor or shaver.
[0003] The state of the art includes general concepts for making toiletries visible in the dark. For instance, US 7,617,828 B1 discloses a toiletries travel kit that may include a razor kit. The document suggests that the handle of the razor may be configured to glow in the dark so that the kit can be viewed at night.
[0004] However, this prior art fails to disclose specific structural implementations of the glow-in-the-dark feature that would provide enhanced functional or safety benefits beyond simple visibility. For example, it does not suggest how the glowing feature might be integrated with other functional parts of the handle, such as a gripping surface, nor does it teach the use of multiple, distinct glowing regions to provide more detailed orientational cues to the user.
[0005] Therefore, a need exists for a hair removal device with improved visibility features that not only allows the device to be located in the dark but also more effectively communicates information about its orientation and structure to the user, thereby enhancing safety and convenience beyond what is currently known.SUMMARY OF THE INVENTION

[0030] The present invention provides a handle for a hair removal device, such as a wet razor or an electric shaver, and related systems and accessories. By providing at least a first glow-in-the-dark region, the handle is easier to see in low-light conditions, such as in a bathroom during the night or in a travel bag. This reduces the risk of a user injuring themselves when reaching for the device, as the glow-in-the-dark feature helps the user to safely locate and orient the device, distinguishing the handle from the hair removal head.
[0031] The handle comprises an elongate holding portion with a first gripping region having a higher coefficient of friction and lower hardness than a second region of the handle. The first glow-in-the-dark region can be realized in several ways. In one embodiment, it may comprise one or more layers of a glow-in-the-dark coating. In another embodiment, the first gripping region itself can be formed from a glow-in-the-dark resin. In a further alternative, the second, harder region of the handle can be provided with the glow-in-the-dark feature, while the softer first gripping region is free of glow-in-the-dark material, creating a distinct visual and tactile contrast.
[0032] FIG. 1 shows a razor handle 100 having an elongate holding portion 101 that comprises a polymeric material, the elongate holding portion 101 having a first end 101a and a second end 101b. The razor handle 100 comprises an attachment region 102 at the first end 101a, the attachment region comprising means 103 for attaching a razor cartridge to the razor handle. The elongate holding portion 101 comprises a first glow-in-the-dark region 104 that, in this embodiment, comprises one or more layers of a transparent or translucent glow-in-the-dark coating on top of the polymeric material. The attachment region 102 may optionally comprise a further glow-in-the-dark region 105.
[0033] FIG. 2 shows a razor handle 100 corresponding to that of FIG. 1, except that the first glow-in-the-dark region 204 comprises a gripping region formed from a glow-in-the-dark resin, such as a thermoplastic elastomer. This gripping region provides enhanced tactile feedback to the user and simultaneously glows in the dark.
[0034] FIG. 3 shows two views of a razor comprising a razor handle 300 and a razor cartridge C. The razor handle 300 comprises an elongate holding portion 301 and an attachment region 302. The elongate holding portion 301 comprises a first glow-in-the-dark region 304 comprising three separate gripping areas formed from a glow-in-the-dark resin on the back side of the handle. An additional gripping region 304a may be present on the front side. The attachment region 302 comprises a further glow-in-the-dark region in the form of a rotatable ball 320, which acts as a swivel mechanism allowing the razor cartridge C to rotate relative to the handle 300.
[0035] FIG. 4 shows a razor corresponding to that of FIG. 3, except that the first glow-in-the-dark region 404 is located in a different area and is instead formed from one or more layers of a glow-in-the-dark coating.
[0036] FIG. 5 and FIG. 6 show further embodiments of a razor handle 500 with an elongate holding portion 501 and an attachment region 502. The attachment region 502 comprises a rotatable disc 525 acting as a swivel mechanism. In FIG. 5, the first glow-in-the-dark region 504 is a gripping area formed from a glow-in-the-dark resin. In FIG. 6, the first glow-in-the-dark region 604 is a coated area on the handle.
[0037] The glow-in-the-dark effect may be provided by any suitable glow-in-the-dark additive, such as a rare earth long persistence luminescent phosphor powder. In certain embodiments, the glow-in-the-dark region has a light color under normal light conditions, for example having a CIE LAB L*value of greater than 50, and preferably greater than 70, to ensure a bright glow.
[0038] FIGs. 7A, 7B, and 7C show various razor accessories 700a, 700b, 700c, such as a razor stand. Each accessory comprises a glow-in-the-dark region 701a, 701b, 701c and an insertion location 702a, 702b, 702c. The glow-in-the-dark regions provide alignment information to a user, for example by surrounding the insertion location (701a, 701b) or by forming the insertion location itself (701c) , making it easier to place a razor into the accessory in the dark.
[0039] Turning now to FIG. 8A, 8B, 9A and 9B, an alternative embodiment is shown as an electric shaver 800, 900. The shaver 800, 900 comprises a handle 801 and a shaver head or hair removal head 802, 902. The handle 801, 901 forms a housing that contains and inner chassis comprising a motor 803, 903 for driving movable blades within the head 802, 903 by the drive pins 804, 904. Both shavers of Figs 8 and 9 differ in the design of the handle housing 801, 901. According to Fig 8A, 8B, the handle 801 comprises a front shell 805 and a back shell 806. The front shell 805 is provided with a display, button area and a first gripping region 808. The back shall 806 may be also provided with a first gripping region 809 –which is made of a material which is higher in the coefficient of friction and lower in hardness, as e.g. achieved by TPE elastomer (soft material) compared to the hard plastic material used for other handle housing parts which may form a second region. In accordance with the invention, any of these components can comprise the glow-in-the-dark region –either as covered layer or as part of the molded resin in the form of fluorescent particles embedded. For example, the soft gripping regions 808 may be formed from a glow-in-the-dark resin. Alternatively, the front shell 805 or back shell 806 may be formed from a glow-in-the-dark resin or have a glow-in-the-dark coating applied. The shaver head 802 or neck area may also be provided with a glow-in-the-dark region. Plastic parts of the head 802 may be provided with a fluorescent additive in the resin or in a coating as with all other plastic based hard or soft components. The metal parts of the head may be also provided with a fluorescent coating.
[0040] The shaver embodiment of Figs 9A, 9B is composed similarly as that of Figs 8A and 8B with the main difference in that the handle housing is completely surrounding the inner chassis like a unitary sleeve or pod. The shaver head or parts thereof may be swiveling supported for better skin contour adaptability.
[0041] The shaver may further comprise a light source 812, such as an LED, integrated within the housing. This light source 812 is configured to intermittently or constantly illuminate the glow-in-the-dark regions from within, thereby "charging" the phosphorescent material and allowing for a prolonged and brighter glow in dark conditions.
[0042] A hair removal system includes the hair removal device 800, 900 and an accessory (not shown) . The accessory can be e.g. a stand, a travel case, or as depicted, a cleaning and charging station. The accessory has a receiving portion for holding the device 800, 900. In a preferred embodiment, the accessory may also include its own light source. This light source is configured to illuminate the glow-in-the-dark portions of the device 800, 900 when it is held by the accessory, for example during a charging or cleaning cycle. This ensures the device 800, 900 is fully "charged" with light photons and ready to glow brightly when removed from the accessory for use in a dark environment.
