Description

Technical Field

[0001] The utility model relates to the field of nail art services in the consumer service industry. Background Art

[0002] One of the main signs of a good manicure is a neat cuticle.

[0003] The stratum corneum is the name of the skin at the base of the nail plate and consists of two layers, the alar layer and the onychodermal layer.

[0004] The nail epithelium is a living part of the stratum corneum that protects the growth area of ​​the nail plate.

[0005] The pterygoid layer is directly attached to the nail plate and consists of keratinized cells, the presence of which creates aesthetic problems, since with it the manicure becomes loose and the decorative layer quickly falls off.

[0006] During a manicure or pedicure, the technician's task is to carefully remove the cornified cells from the stratum corneum (a thin film of dead cells at the bottom of the stratum corneum) without damaging the nail epithelium.

[0007] When performing a hardware manicure and pedicure, special working attachments are used to handle the nails and remove the wing layer.

[0008] Cuticle treatment and wing removal are one of the most labor-intensive stages of the manicure process.

[0009] A replaceable tip for manicure and pedicure is known, which has the shape of a truncated cone and whose side surfaces are abrasive (Russian Patent No. 2532145 of October 27, 2014, "Manicure and Pedicure Method", IPCA45D29 / 00).

[0010] Only a thin layer of the alar layer directly adjacent to the lunula can be effectively removed using known working tips, but removal of the alar layer deep in the stratum corneum often causes damage to the nail epithelium and nail plate.

[0011] The injured surface begins to densely proliferate and be covered with scales, and then a scar is formed.

[0012] Persistent scarring of the injured surface, in turn, leads to hyperplasia of the winged layer and the formation of cuticles, where dry scales are lifted, which quickly deteriorates the appearance of the nail and requires early repetition of the surgery.

[0013] A replaceable tip for manicure and pedicure is known, comprising a rod inserted into a manicure instrument and a working part in the shape of a truncated cone having a smooth base forming a bottom and an abrasive side surface (Eurasian Patent No. 039516 "Manicure method" from February 4, 2022).

[0014] A disadvantage of the known tip is that during the removal of the alar layer, the cutting tool, which exerts a constant pressure, comes into contact with the lower stratum corneum with greater force than with the upper and middle stratum corneum, which creates a risk of injury to the lower stratum corneum.

[0015] To reduce the possibility of injury to attached bones, the bottom of the working part should be kept at least 0.4 mm away from the deck surface.

[0016] Furthermore, in order to obtain good results, it is necessary to use less pressure when treating the lower stratum corneum than when treating the upper and middle stratum corneum.

[0017] Damage to the nail epithelium is unavoidable using known devices and increases the labor intensity of the manicure and pedicure process and the time required for the process. Utility Model Content

[0018] The utility model develops the replaceable tip for manicure and pedicure to reduce the possibility of damaging the nail epithelium and reduce the labor intensity of the manicure and pedicure process, thereby reducing the time required for the manicure and pedicure procedures.

[0019] The above-mentioned object is solved by incorporating a rod into a replaceable tip for manicure and pedicure, which is inserted into a manicure instrument, the replaceable tip being made in the shape of a truncated cone, whose smooth bottom surface forms the bottom, according to the utility model, there is an edge at a distance of 0.4 mm to 0.6 mm from the bottom, a part of the abrasive side surface of the working tip between the edge and the bottom is inclined at an angle of 40° to 50° with the edge, the diameter of the edge is 2.9 mm to 3.2 mm, the diameter of the bottom is within 2.4 mm to 2.7 mm, and a part of the abrasive side surface between the "edge" and the bottom is made into a smooth radius chamfer.

[0020] The edge of 0.4 mm to 0.6 mm from the bottom, and the abrasive side surface at an angle of 40° to 50° to the edge, the edge of 2.9 mm to 3.2 mm in diameter and the bottom of 2.4 mm to 2.7 mm in diameter, and the design of the abrasive side surface with a smooth radial chamfer between the edge and the bottom ensures close contact of the abrasive side surface. As well as the design of the abrasive side surface between the edge and the bottom with a smooth radial chamfer, it can ensure that the abrasive side surface of the working part of the tool tip and the stratum corneum are in close contact over the entire depth, and also ensure that the pressure exerted by the two parts of the abrasive side surface on the stratum corneum is evenly distributed.

[0021] Since the geometrical parameters of the working parts of the replaceable tips for manicure and pedicure are optimally adapted to the anatomy of the human finger and ensure safe treatment of the cuticle over its entire depth, the likelihood of causing damage to the epidermal layer below the cuticle is reduced.

[0022] In addition, the use of such replaceable tips for manicure and pedicure can also reduce the labor intensity during the processing, because the close contact of the abrasive side surface of the tip working part and the uniform distribution of pressure can reduce the time required for the manicure or pedicure procedure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the utility model. DETAILED DESCRIPTION

[0024] The utility model is described with reference to drawings depicting pointed tips for manicure and pedicure, and a specific example of its application is described.

[0025] Figure 1 The replaceable tip for manicure and pedicure comprises a stem 1 which is inserted into the manicure instrument and a working part 2 which is in the shape of a truncated cone with a smooth bottom surface forming a base 3 and abrasive side surfaces.

[0026] The bottom 3 has an edge 4 at 0.5 mm, the abrasive side surface L1 of the working part 2 between the edge and the bottom 3 is at a 45° angle to the edge, the diameter of the edge 4 is 3.1 mm, the diameter of the bottom 3 is 2.5 mm, and there is a smooth radial chamfer R between the edge 4 and the abrasive side surface L2 of the bottom 3, the length of which is consistent with the distance from the bottom 3 to the edge 4, which is equal to 0.5 mm.

[0027] The manicure process begins by removing the cuticle from the nail plate.

[0028] To remove the cuticle from the nail plate, use clippers or a manicure spatula to lift the nail plate edge, cuticle, and epidermis away from the nail plate.

[0029] Use the replaceable tip to further treat the periungual skin.

[0030] To this end, the abrasive side surface of the replaceable tip rotating at a speed of 12,000 revolutions per minute applies slight pressure to the stratum corneum along the entire depth of the stratum corneum and maintains it for 6 to 7 seconds at each contact point, while the lower chamfered portion of the abrasive side surface L2 cuts off the lower layer of the stratum corneum that directly contacts the nail plate, and the portion of the abrasive side surface L1 cuts off the upper part of the stratum corneum, while grinding its inner surface at each contact point and forming a rounded longitudinal ridge of the nail without contacting the nail bone.

[0031] Begin working the periungual skin from the left side first, then move the tip to the right using a clockwise, back-and-forth rocking motion while holding the base 3 of the tip against the nail plate.

[0032] After treating the cuticle, use the side abrasive surface of the tip to treat the lateral longitudinal ridges of the nail.

[0033] Therefore, this replaceable tip for manicure and pedicure can simultaneously cut off the wing-like layers of each layer of the cuticle and polish the inner surface of the cuticle at the same time.

[0034] The replaceable tip allows the alar layer below the cuticle to be removed without touching the surface of the nail epithelium, which greatly reduces the possibility of damage to the nail epithelium and allows the cuticle and the surrounding ridges of the nail epithelium to be neatly shaped.

[0035] Using this interchangeable tip for manicure and pedicure ensures that both the nail plate and the periungual ridge are treated with a single tool, reducing labor costs and shortening the time required to treat one finger to one minute and the time required to treat both hands to 10 minutes.

[0036] The replaceable tips for manicure and pedicure allow easy and quick cleaning of cuticles to a safe depth without damaging the cuticles, thus permanently eliminating the "sticky" cuticle effect on the nails, which in turn improves the quality of manicures and pedicures and increases the time between operations.

[0037] Such replaceable tips for manicure and pedicure are easy to manufacture, safe and effective to use, and can be manufactured in an industrial production environment using standard materials on standard equipment.
