Definitions

  • the invention is in the field of personal care and relates to a shaving device for wet shaving (blade shaving) according to the preamble of the independent claims, with which hair on any part of the body (surface, rounding or contour shaving) using any preparation (for example problem shaving), that is applied by the device while shaving, can be cut off very close.
  • a lubricant and softener any problem shave
  • the flat application of thin layers of such cosmetic (possibly pharmaceutical) preparations to the skin is usually carried out by hand or by spraying.
  • a good dosage and a very regular distribution is difficult. It is unavoidable that part of the sometimes expensive preparation to be applied remains on the application hand.
  • spray cans with which the application problem is also not solved are no longer desirable because of environmental pollution.
  • the hygiene problem always remains current.
  • the object of the invention to provide such a device with the aid of which a pumpable preparation can be applied as a thin, regular layer over a wide area and in a manner suitable for cutting.
  • the supply of preparation for application should only be possible during the application or pumping process be. If not applied, all feed routes should be automatically interrupted and shielded. For hygienic reasons, it should be prevented that contaminants are brought into the preparation from outside. It should be easy for the user to precisely dose the preparation.
  • the device is said to be suitable for shaving for women as well as for men. For women-specific shaving, areas with greater curvatures, i.e. rounding shaving (concave and convex), are required, while for men-specific shaving, areas with predominantly less pronounced curves are in the foreground. But the so-called "dimple problem" has always been an issue for men-specific shaving and it is not least due to the requirements of women-specific shaving that these problems of male shaving can also be solved.
  • the device according to the characterizing parts of the independent claims consists of an applicator part, a fluid supply part and a blade part.
  • the following description and the associated figures first deal generally with the interaction of the applicator part and the blade part ( Figure 1), then in detail with the applicator part ( Figures 2 and 3), with the feed part ( Figures 4 to 8) and finally with the integration of the blade part to a razor according to the invention ( Figures 9 to 14), in which the three parts come together to work.
  • the blade part and applicator part are formally matched to one another; the feed part including the reservoir is functionally matched to the applicator part, so that the applicator part on the one hand doses to the blade part and the shield to the dining area.
  • this intermediate link can be designed in many ways, can be adapted to any blade shape and controls the pumped-in flow of the fluid from its reservoir.
  • the application opening is preferably slit-shaped.
  • the elements delimiting the opening can be movable or rigid. If they are movable, the mobility can be used for application (for example, rollers) or for shrinking to cover the opening (for example, swivel axis of a roller) or for both.
  • the elements delimiting the opening can be arranged in relation to the blade part (one or more cutting edges) in such a way that the cutting is mechanically supported, so that the geometry of the cutting edge (s) and opening limiting element (s) is of additional importance.
  • the application opening is in turn connected via the feed part to the fluid reservoir, which is shielded by the feed channel and the delimiting elements, in order to meet the hygiene requirements.
  • 1.1 shows an abstracted schematic representation of the feeding, application and cutting function of a shaving device.
  • An application angle is designated by ⁇ and a cutting angle is designated by ⁇ , the angle ⁇ being greater than the angle ⁇ for trouble-free shaving.
  • the two angles relate to the skin surface H.
  • an applicator part (manipulation part) 30.2 influencing the cutting angle, which on the one hand delimits the application opening on the blade side and optionally the Fluid channel 10 is the closing part.
  • a crossed double arrow shows the adjustment options. Pushed towards the skin surface, it causes a local pushing back of the skin surface H into the position H '.
  • the scraping A that is hair and abrasion of the preparation and skin, can be removed between the blade 2 and the manipulation part 30.2.
  • the fluid In the fluid channel, the fluid is conveyed to the applicator part under a certain pump pressure (arrow p) and emerges at the application opening in the area of the skin surface. If the blade part is moved in the cutting direction, the applicator part distributes the preparation over the skin surface.
  • FIG. 1.2 shows an embodiment according to the invention, in which the fluid channel 10 of the applicator part can be closed or at least narrowed by a roller-shaped addition on the wall parts 30.1, 30.2.
  • the applicator part 30.2 (manipulation part) influencing the cutting angle is, for example, a cylindrical roller 3 which on the one hand delimits the application opening on the blade side and partially covers the fluid channel by its position.
  • the adjustment options are indicated by a double arrow if the roller 3 is mounted in a slot-shaped bearing.
  • the channel is covered more or less.
  • the skin surface is influenced more or less, that is, locally pushed back into a position H '.
  • roller-shaped manipulator part 30.2 If the roller-shaped manipulator part 30.2 is now brought into a rest position, in which the outlet opening of the fluid channel 10 is closed, for example by means of spring pressure, movement of the blade part in the cutting direction causes the latter to open, so that the fluid under pump pressure can emerge unhindered. At the same time, roller part 30.2 spreads it on the skin surface.
  • FIG. 1.3 shows a schematic section through an exemplary embodiment of the device according to the invention, which consists of the three parts, namely an applicator, a cutting device and a feed device from which the preparation is fed into the applicator.
  • the applicator corresponds to the roller solution according to Figure 1.2.
  • the cutting device is integrated in the applicator, that is to say the cutting device and applicator together form the shaving head 1.
  • the main component of the applicator is an application roller 3 arranged parallel to the blades 2.
  • the feeding device is accommodated in the handle 4 of the device and consists of a small pump 5 and a reservoir 6.
  • the shaving head 1 is pulled over the skin with the aid of the handle 4 in such a way that the application roller 3 rolls over the skin immediately in front of the blades 2.
  • the pump 5 is positioned in such a way that it lies between the thumb and forefinger and, depending on the embodiment, can be actuated by slightly alternating pressing and releasing.
  • the preparation is pumped from the reservoir 6 into the applicator and distributed as a thin film on the application roller 3 and transferred from there to the skin.
  • the dosage is easy. If the dosage is too short, the application roller runs dry, and if the dosage is too strong, it forms droplets.
  • the applicator consists of an application roll and a feed system.
  • the application roll is rolled over the skin for the application, for example. It is, for example, rotatably and pivotably mounted so that it is swiveled out in one direction (application direction R) when unrolling, while it remains in its rest position when unrolling in the other direction and, if it is not rolling. Swiveling out makes it possible for a thin film of preparation to be carried outwards from the feed system on the roll surface. In the rest position, the application roller shields the feed system from the outside. In another embodiment, the application roller is fixed and the gap width remains constant. This embodiment is suitable for preparations that do not dry out too much and tend to form little film. In a further embodiment, the application roller can also only be pivoted, but not rotatably, so that it closes and opens the application opening, but acts for the application itself in approximately the same way as an application spatula, as will be described below.
  • FIG. 2a shows an applicator from the side. It consists of the roller 3, a head piece 21 and two bearing parts 22 attached laterally from the head piece 21.
  • the bearings 23 in the bearing parts 22 are either designed so that they not only rotate the roller 3 about its axis of rotation, but also pivot it out Allow axis of rotation or so that they only move about their axis of rotation.
  • the first variant results in a variable application gap width and in the second variant a fixed application gap width.
  • FIG. 2b which represents a separate bearing part 22, a bearing 23, which enables a variable application gap width, is also shown separately.
  • FIG. 3a shows a section through the head part 21 of the embodiment of the applicator shown in FIG. 2a.
  • the bore opens into a channel 32, which runs parallel to roller 3 and is open towards roller 3.
  • the bore is designed in accordance with the connection to the feed device.
  • the head part is shaped into lips 33.1 and 33.2 on both sides of the channel 32.
  • the bearings of the roller 3 in the bearing parts 22 are designed in such a way that the roller can assume two extreme swivel positions: a “rest position” (shown in solid lines in the figure) and an “application position”"(shown in dashed lines in the figure).
  • a “rest position” shown in solid lines in the figure
  • an “application position” shown in dashed lines in the figure.
  • the width of the column A does not change, while the column C widens until its width in the application position corresponds to the desired exit quantity for the preparation.
  • the application position for a desired exit quantity can also remain fixed, so that the rest position corresponds to that of the application position.
  • the shielding is then good or better, depending on the film formation, the drying is good or worse.
  • the roller 3 If, in the case of the embodiment with a variable application gap, the roller 3 is pulled over the skin in the application direction, it is rotated by the friction between the skin and the roller in the direction of the arrow R and thereby swung out into the application position and held in it. If the roller 3 is rotated in the direction opposite the arrows R, it is pivoted into the rest position and held in this position. If the roller 3 is in its application position, but is no longer rotated in the direction of application, which is the case immediately after application, it is withdrawn against the rest position by the surface tension of the preparation surface in the gap C. The physical properties of the preparation are therefore used to close gap C after application. The surface is under tension that tries to reduce the surface to a minimum.
  • the roller is moved against the rest position as soon as it is not in the opposite direction by the application movement is pressed. If the applicator is left to its own devices after the gap C has been closed by the surface tension, a skin forms in the gap C by drying the preparation surface, which shields the rest of the preparation from the outside in the delivery system. This shielding is sufficient to prevent further drying of the preparation and to protect the preparation against oxidants and bacteria, for example. When reapplied, the skin covering gap C is immediately torn and does not interfere with the application in any way.
  • the gap A between the lip 33.1 and the roller 3 is very small in any pivot position (open / closed or for, correspondingly open) of the roller 3, the channel 32 on the side of the lip 33.1 is always closed to the outside. In the rest position and in the application position of the roller 3, no preparation can get out in this direction, in the application position no contamination that carries the roller from the skin can pass the lip 33.1 into the channel 32. In the embodiment with a fixed gap, this is only weakened.
  • a lid which is placed on the applicator after the application has ended and which is shaped in such a way that it presses the roller 3 against the two lips 33.1 and 33.2 or simply covers the application gap.
  • additional mechanical pressing means for example springs, can be provided in order to press the application roller 3 against the sealing lip. This may be necessary if, for example, such a shaving device is exposed to strong pressure fluctuations in travel versions and an additional closing force is desired on the device.
  • FIG. 3b shows a section through the embodiment of the applicator according to the invention with a variable gap. It shows the same parts as the applicator shown in FIG. 3a, but a blade carrier 34 with blades 2 is placed on its head part 21 by means of, for example, a sliding and snap fastening.
  • the roller 3 is advantageously as long as the width of the blade or blades 2.
  • the blade carrier 34 is placed on the head part 21 in such a way that the roller runs parallel to the blades and when the shaving head is guided over the skin in the shaving direction (same as the application direction) is rotated in the direction of arrow R and is thereby pivoted into the application position.
  • the application device with application roller 3, head part 21 and bearing parts 22 can also be integrated in an interchangeable blade carrier which can be placed or exchanged as a whole on a razor head.
  • This solution has hygienic advantages because the application roller that comes into contact with the skin is periodically renewed with the blades.
  • the supply part arranged on the blade carrier is connected to the supply part arranged on the razor by suitable measures.
  • FIG. 4a shows a schematic longitudinal section through an exemplary embodiment of the feeding device according to the invention.
  • this consists of a small pump 5 and a reservoir 6, both of which together, for example, simultaneously form the handle 4 of the application device, or are accommodated in a corresponding handle.
  • the reservoir 6, as shown, is accommodated in the end 4.1 of the handle (reservoir part of the handle) facing away from the applicator, where a sufficient volume does not have a disruptive effect.
  • the small pump 5 is advantageously arranged in such a way that it can be actuated during application, that is to say its actuating members are located in the region of the fingers holding the handle during application, that is to say at the end of the handle facing the applicator, and forms the pump part 4.2 of the handle .

  • This can be, for example, a piston 48 movable in the reservoir 6 or a pressure compensation valve.
  • an inner pump body 44 is attached inside the bellows 41, which in this exemplary embodiment has the shape of a tube, fixed to the reservoir part 4.1 of the handle and is connected to the connecting part 4.3 and is provided with openings 45 for pressure equalization. Because the inner pump body is angled, it forms an ergonomic handle together with the other parts of the feed device.
  • the bellows 41 is placed over the inner pump body 44 and clamped in place with elastically deformable means 46, for example clamping rings.
  • the two one-way valves 42 and 43 are, for example, diaphragm valves.
  • a resilient membrane 47.1 keeps the outlet of the reservoir closed in the force-free state and a corresponding membrane 47.2 keeps the entrance to the applicator closed.
  • the two membranes are arranged in such a way that the membrane 47.2 is deformed in the event of overpressure within the bellows, but the membrane 47.1 in the event of underpressure.

  • FIGS. 14a to c show examples in which the course of the cutting blades essentially follows the course of the application roller (whereby such shapes can also be transferred to the application spatula). Deviations from this shape can also make sense, but the shape of the application roll should be functionally related to the blade shape.
  • the options outlined here only represent suggestions for further development and therefore only one application roller 3 and blades 2 are shown here in their relative arrangement.
  • FIG. 14a shows a typical arrangement with a cylindrical application roller 3a for shaving skin surfaces that can be deformed from the application roller into a flat surface
  • FIG. 14b shows an arrangement with a convex application roller 3b for shaving concave surfaces such as depressions, for example in the armpits, which are no longer accessible with the linear blade
  • 14c shows an arrangement with a concave application roller 3c for shaving convex surfaces such as elevations, for example on the larynx, in which the linear blade would entail an increased risk of injury.
