Description

The present invention relates to a razor and a method of making a razor.

For the purposes of the present invention, shaving means cutting the hair on the skin to just above the top layer of skin with at least one blade. The hair is not removed, but only shortened.

Known razors comprise an elongated handle part which is connected to a blade head. When used as intended, the handle part lies in the hand of the user to allow the blade head to slide over the user's skin.

Such razors are usually used for wet shaving, but it is also possible that a razor in the sense of the present application also has an energy supply (for example battery or rechargeable battery) which causes a vibration in the blade head in order to bring about a massage effect and / or the thoroughness to increase the shave.

These razors are available as single-use items, with permanently installed or exchangeable blade heads and a wide variety of blade head variations with different numbers of razor blades.

DE 29503575 U describes a handle part for a razor, which is provided at one end with a receiving device for a holder with blades arranged therein. The handle is designed as a leaf spring.

DE2851457A1 describes an insert for a razor with a blade rest, a razor blade and a cap, wherein an integral solid and water-soluble shaving aid is provided.

DE20216827U1 describes a two-part shaving set for manual wet shaving consisting of a razor with a handle and a shaving brush. The hollow telescopic handle can alternately hold and hide both the shaving brush and the shaving head with razor block inside, the same telescopic handle serving as a handle for the user when soaping and shaving.

US2008072431A1 describes a shaving device with multiple parallel blades with a flat part and curved end portions for shaving curved areas of a body.

US5903978A1 describes a curved razor handle.

It is an object of the invention to provide an improved razor.

The invention relates to a razor with a handle with a handle part and a flexibly flexible head part for receiving a blade head, and the blade head, the blade head being designed as a brush head and / or brush head with bristles, at least one of the bristles having a razor blade.

The invention is based on the idea that a razor which has bristle-like razor blades is more pleasant and reliable to use for shaving. The bristles adapt flexibly to any skin irregularities or curvatures and thus enable a particularly thorough shave even in areas of the skin that are difficult to access. The bristles glide smoothly over the skin, which makes shaving particularly pleasant for the user. A thorough and pleasant shave without great effort for the user is made possible.

The blade head designed as a brush head / brush head has a base body made, for example, of plastic, the front side (the side facing away from the head part) forming the brush back / brush ferrule on which the bristle trim of the at least one bristle with at least one razor blade is arranged.

The bristles can have different lengths, widths, cross-sectional shapes, etc. and can also consist of different materials. Also, some of the bristles may not have a razor blade, but only a strip of balm to care for the skin of the user during the shave. Also, some of the bristles cannot have a razor blade, but only a special blade. However, it can also be preferred that one or more bristles have both one (or more razor blades) and one (or more) special blade and / or one (or more) balsam strips.

A razor according to the invention advantageously enables shaving like a brush stroke. The blade head preferably has a plurality of relatively small blades which are arranged on bristles and are thus flexibly movable relative to one another. According to the invention, a sensitive shave is made possible because the blades lie closer and more directly on the skin, which in particular on the knees and ankles ensures an improved thoroughness of the shave. An extremely sensitive shave is made possible, with which only slight pressure on the blade head is necessary. The razor blades of the bristles adapt "as if by themselves" to the skin surface of the user.

In particularly preferred embodiments, the razor according to the invention has a blade head with razor blade bristles which are arranged in a row next to one another. The individual razor blades are attached to flexible bristles (also referred to as "lamellae") that can be moved flexibly against one another. The bristles are anchored to a flat blade head, which acts as a kind of brush head, which is designed to be exchangeable. The razor blade bristles consist, for example, of commercially available elastic material and impress with their size and flexible use, which is reminiscent of a brush stroke. The flexibility and smoothness of the shave can be guaranteed by elastic lamellae made of a thermoplastic elastomer. Advantageously, the blades lie closer and more directly to the skin and therefore less pressure on the razor is required for shaving.

The flexibility and smoothness of the shave is ensured according to the invention by lower pressure on the razor and the flexible razor blades. The shave is ergonomically appealing and reduces the risk of cuts.

In one embodiment, the bristles have one or a plurality of razor blades. Each of the bristles can have one or more razor blades. The razor blade (s) is / are arranged essentially at right angles to the longitudinal axis of the bristle (s). The razor blade (s) is / are arranged on an underside of the bristle (s) which, when the razor is used as intended, slides over the user's skin to perform the shave. However, it can also be preferred that only one or some of a plurality of bristles has one or more razor blades. The inventive arrangement of razor blade (s) on bristle (s) enables a particularly gentle and thorough shave, since the bristles adapt particularly smoothly to the unevenness of the skin surface. For example, a razor has a variety of bristles with a variety of Razor blades, they can be particularly flexible against a flat skin (for example the ankle or knee) in order to shave the razor over this area of the skin with just one or a few movements.

In one embodiment, at least one of the bristles has a special blade (s) and / or a balsam strip. Each of the bristles can have one or more special blade (s) and / or balsam strips. The special blade (s) and / or balsam strip is / are preferably arranged essentially at right angles to the longitudinal axis of the bristle (s). The one or more special blade (s) and / or balsam strips is / are arranged on an underside of the bristle (s) which, when the razor is used as intended, slides over the user's skin in order to perform the shaving and / or care of the skin. The arrangement according to the invention of one or more special blade (s) and / or balsam strips on bristle (s) enables particularly gentle and thorough shaving and care because the bristles adapt particularly smoothly to the unevenness of the skin surface. If, for example, a razor has a large number of bristles with a large number of one or more special blade (s) and / or balsam strips, these can be applied particularly flexibly to a skin flatness (for example the ankle or knee) in order to use only one or a few Moving the razor over this area of skin to shave and care for it at the same time.

The razor can advantageously be supplemented by one or more special blades. The blade head therefore preferably has different blade types, which enables improved, more precise shaving in different skin areas of the user. For example, the razor blade (s) of the blade head can be suitable for a large-area shave, which can be refined by using one or more smaller special blades (s) arranged on one or more bristles. Depending on requirements, different blade heads with different special blades can be arranged on the shaver, which advantageously increases the flexibility in use.

A balsam strip in the sense of the present application can be a strip which has, for example, a shaving soap, a moisturizer, a skin-soothing care product, an oil or the like. The balsam strip is preferably arranged on the bristle along the longitudinal axis of a bristle, adjacent to the at least one razor blade and / or the at least one special razor blade. It is advantageously achieved that the skin is not only shaved, but also treated and cared for with the balm strip.

In one embodiment, the razor blade (and / or special blade) is designed as a notch and / or cut in the bristle surface. The at least one razor blade is preferably formed on the at least one bristle, in that the bristle has an incision on the underside of the bristles which, when the razor is used as intended, lies on the skin of the user to be shaved. The incision is made essentially at right angles to the longitudinal axis of the bristle. The incision can be designed as a wedge-shaped notch, which tapers in the direction of the bristle tip. In such an embodiment, the notch is only activated as a razor blade when the bristle rests on the surface of the skin and deflects under the contact pressure, which leads to a curvature of the bristle and thus a spreading of the notch. The bristle surface on the underside of the bristles thus has an essentially smooth surface when not in use, which advantageously prevents cuts or damage to and by the bristles. Only when the bristle is bent when used as intended, the razor blade of the notch is released to enable the speeders.

In one embodiment, the bristles have an elastic material. The bristles can be made of the same material, or it can preferably be that the bristles arranged on the outside of the blade head are made of a material with less elasticity than the bristles arranged between them. This advantageously enables the unevenness of the skin of a knee or ankle to be represented particularly well by the bristles brushing over it with different elasticity or strength.

In one embodiment, the bristles are arranged next to one another and parallel to one another on the head part. The blade head is preferably designed as a flat brush head. A row of bristles is preferably arranged next to one another on the blade head (preferably essentially along the transverse axis). It can be preferred that the bristles are arranged parallel to one another or as compartments. Depending on the use for different body areas of the user, blade heads with different bristle designs and arrangements can be arranged on the head part.

In one embodiment, the blade head is concave along the razor's transverse axis. It is advantageously achieved that the blade head has a curvature that essentially corresponds to a curvature of the skin surface of the user. It may be preferred that blade heads with different radii of curvature (which are adapted for different areas of the skin surface of the user) can be arranged on the razor. The underside of the blade head and thus the bristles arranged on it can slide particularly well along the skin of the user when the razor is designed as intended when the razor is used as intended. In a preferred embodiment, the bristles are therefore arranged along a curved line or row (front end of the blade head), so that they adapt particularly well to the curved skin surface of the user. In one embodiment, the row of bristles is at least partially concavely curved. In a preferred embodiment, the head part of the handle can also be concave along the transverse axis of the razor.

In one embodiment the handle is convex along the longitudinal axis of the razor. It can also be preferred that the handle is described in a slightly curved shape and consists of a solid, impact-resistant material (e.g. ABS (acrylonitrile-butadiene-styrene)). A convexly curved handle can be used more ergonomically and also more reliably for shaving, since the handle or handle part, which is essentially matched to the concave palm of the hand, enables particularly ergonomic handling.

In one embodiment, the head part has a recess in which the blade head is arranged. The blade head is preferably connected to the head part by means of the recess. In one embodiment, the blade head is fixed in the recess by means of holding elements, for example locked by means of locking elements. Since the blade head is only fixed in the recess by means of positive locking or simple holding elements, a flat surface of the razor can advantageously be provided, which improves handling and enables a comfortable shave.

In one embodiment, the grip part has at least one grip element for the user to hold the grip in a non-slip manner. In one embodiment, the top of the

Handle section Handle elements for non-slip holding of the handle by the user. The handling of the razor and its hold in the hand of the user can advantageously be further improved by grip elements (also referred to as "flu elements") such as roughened areas, a corrugation, an adhesive surface, areas of a non-slip material on the top (or else also in an optional concave curvature of the underside) and / or concave / convex curvatures are provided. The handle is thus particularly good in the hand, particularly safe handling of the razor is made possible and the razor is prevented from "slipping away".

The razor according to the invention is advantageously suitable for partial or full body shaving and in particular for shaving in the shower due to its flexible application options.

In another aspect, the invention relates to a method of making a razor of the present invention, comprising the steps of: providing a handle with a handle portion and a head portion for receiving a blade head, and arranging the blade head on the head portion, the blade head being a brush head and / or the brush head is designed with bristles, at least one of the bristles having a razor blade.

In a preferred embodiment, the blade head and / or the bristle has one or more pressure points which visually signal to the user whether and / or how much pressure is present between the bristle and the skin of the user when the razor is used as intended. In this way, the user can advantageously see particularly well whether the area of the skin to be shaved is subjected to sufficient pressure to shave.

In a preferred embodiment, the head part and handle part are formed in one piece.

In a further embodiment, the razor has a sliding element (preferably a sliding pin), which is designed to change the flexible flexibility (possible curvature upon deflection) of the head part.

In a preferred embodiment, the blade head comprises one or more blades, the cutting edges of which form a plane. The cutting edge plane of the blade (s) is advantageously formed in a plane with the skin support side of the head part. When the shaver is used as intended, the side of the skin on the skin is the underside of the head part. The blade head lies essentially in the plane of the underside to allow a smooth underside of the razor that glides particularly comfortably over the skin. This also ensures that there are no blade edges or fastening elements (since the blade head is integrated in the head part in a form-fitting manner) that could be disruptive when shaving. Furthermore, the substantially flat contact surface of the underside of the head part on the skin offers security in order to prevent the blade head from tilting and damaging the skin.

In a further aspect, the invention relates to a razor set comprising: a razor according to one of the above-mentioned aspects (preferably the second aspect) of the present invention, and a holder for positively receiving at least part of the razor.

Figures 1a and 1c show a razor 1 from above, and Figures 1b and 1d from underneath. Figures 2a and 2b show detailed views of the blade head 20.

The razor 1 has a handle 10 with a handle part 11 and a head part 12. The head part 12 in turn has the blade head 20, which is equipped with at least one razor blade 21 on at least one bristle 29. In the in Figures 1 to 5 In the embodiments shown, the blade head 20 has a multiplicity of bristles 29 with a multiplicity of razor blades 21.

The handle 10 can have handle elements (not shown) which enable the user to hold the handle in a non-slip manner. The blade head 20 or the bristles 29 can have balsam strips (not shown) with emulsions and nourishing oils and / or special blades (not shown).

In Figures 1 and 2a it is shown that the handle 10 is convex along the longitudinal axis of the razor 1 and the blade head 20 is concave along the transverse axis of the razor 1. The bristles 29 are made of an elastic material and are arranged next to one another and essentially parallel to one another on the head part 20.

In Figure 2b is shown by way of example how a plurality of razor blades 21 are shaped as notches in the bristle 29. The bristle 29 is anchored to the blade head 20 and formed from an elastic material, which is shown in Figure 2b is indicated by the arrow. If the bristle 29 is deflected by lying on the skin of the user and sliding over it, the razor blades 21 are spread open by the bristle 29 being bent and thus activated. If the bristle 29 is relieved by being removed from the skin, the bristle 29 assumes its original shape and the notch closes again, so that the razor blade 21 is deactivated.

Figures 4 and 5 illustrate further embodiments of the razor 1. Insofar as the features of the further embodiments correspond to those of the previously described embodiments, reference is made to the features described above.

The embodiment of the Figure 4 differs from the embodiments of FIG Figures 1 and 3 essentially in the shape of the handle 10 and the arrangement of the razor blades 21. The razor blades 21 are in the embodiment of the Figure 4 arranged at the bristle tip, whereas in the embodiments of the Figures 1 and 3 are arranged in a tip region (front half, front third of the bristle 29), but not at the tip.

The embodiments of the Figures 1 to 5 thus have razor blades 21 which can be moved flexibly relative to one another (in particular next to one another), the razor blades 21 being arranged side by side on bristles 29. Individual razor blades 21 can in turn be attached to one another (one behind the other) so as to be movable on each bristle 29 (elastic lamella). The slats 29 are anchored to a flat blade head or brush head 20, which at the same time represents the exchange unit for the razor 1,

The razor blades 29 can be anchored in the bristle 29 as commercially available blades or can be designed as a notch in the bristle surface. The razor blades 29 particularly impress with their size and flexible use, which is reminiscent of a brush stroke. The flexibility and smoothness of the shave is also ensured by the elastic slats 29 made of thermoplastic elastomer. The razor blades 21 are thus advantageously closer and more directly to the skin. A lower pressure on the shaver 1 is therefore required for shaving. Shaving with the razor 1 is ergonomically appealing and protects against cuts. The handle 10 is ergonomic, is described in a slightly curved shape and is made of solid, impact-resistant material (e.g. ABS (acrylonitrile-butadiene-styrene)) and can also be used with grip elements such as roughened Zones, corrugation and non-slip materials are covered.

Figure 6a shows a razor 1 from below, Figure 6b from above and Figure 6c when used as intended on the skin of the user.

The razor 1 has a handle 10 with a handle part 11 and a flexibly flexible head part 12 and a blade head 20 which is positively integrated into the head part 12.

In addition to the razor blades 21, balsam strips 24, 25 are arranged, which care for the user's skin with each brush stroke or feather stroke of the razor 1. The blade head 20 has a plurality of blades 21, the cutting edges of which essentially form a plane with the underside of the head part 12 (skin support side).

Head part 12 and handle part 11 are formed in one piece and the head part 12 is wider than the handle part 11. The blade head 20 is not detachably arranged in the head part 12.

Figure 7 shows a razor set with a razor 1 of Figure 6 , and a holder 30 for positively receiving the handle 10 or handle part 11 of the razor 1.

In Figure 8 a razor 1 is illustrated, the blade head 20 of which has a plurality of pressure points 33 which visually signal to the user whether and / or how much pressure is present between the blade head 20 and the skin of the user when the razor 1 is used as intended. The pressure points 33 can have, for example, pressure sensors or temperature sensors.

For example, piezo elements can be integrated in the pressure points, which then emit optical or electrical signals depending on the pressure.

In Figure 9 a razor 1 is illustrated which has a plurality of razor blades 21, a balm strip 25 and a special blade 23 on the blade head 20. The special blade 23 arranged at the tip can be used for fine shaving or for shaving particularly uneven areas of skin.

The razor 1 of the Figures 9b and 9c additionally has a push pin 13 which is designed to change the flexible flexibility (possible curvature upon deflection) of the head part 20. So the head part 20 in Figure 9b perform a relatively large deflection, whereas the push pin 13 in Figure 9c the deflection of the head part 20 blocked or difficult.

The push pin is advantageously made of different elastic material than the handle material in order to achieve a change in the deflection.
