  • Known similar replaceable abrasive cleaning devices for nail care among which the following are the following.
  • the abrasive element is disposable and disposable.
  • the replaceability of the abrasive element is achieved by the fact that an adhesive layer is applied to one of its sides and with the help of this layer the abrasive element is connected to the working plate (patent UA 122100 U, published on December 26, 2017).
  • the disadvantage of such an abrasive element is the insufficient reliability of its fixation on the working plate only with the help of an adhesive layer applied to one side of the abrasive element, and the possibility of displacement of the abrasive element during operation due to the lack of its mechanical fixation on the working plate.
  • the reliability of fixation for such an abrasive element will depend on the quality of the adhesive layer and the strength of its adhesion to the surface of the working plate, on the other hand, too strong adhesion will complicate the peeling off of the abrasive element when it is replaced.
  • the prototype is the removable abrasive sleeve of the nail care device described in the patent UA 118314 U, published on July 25, 2017.
  • the sleeve according to the prototype contains a base in the form of a flat or flat-oval tube, the surface of which has an abrasive working part.
  • the base provides the ability to quickly put on the working plate by moving the working plate into the cavity of the base tube, followed by its removal after the abrasive working part is demolished and replaced with new abrasive sleeve.
  • the abrasive working part is made in the form of an abrasive cloth installed on the base by gluing.
  • the disadvantage of this solution is the insufficient strength of the base, the integrity of which can be damaged during the use of the device for nail care, for example, in the event of its rupture, which reduces the reliability of using the removable abrasive sleeve and the possibility of injury to the treated surface of the nail.
  • a decrease in the reliability and safety of using a removable abrasive sleeve according to the prototype can also lead to the conjugation of the abrasive cloth over the entire surface of the base, especially in the places where the flat or flat-oval tube is rounded, as well as the lack of damping of the abrasive working part during the operation of the nail care device.
  • the basis of the invention is the task of increasing the reliability and safety of using a removable abrasive sleeve with a device for nail care by increasing the strength of the base and the reliability of the mating of the abrasive cloth with the surface of the base.
  • the abrasive working part is formed by an abrasive cloth connected to the flat surface of the base, while the base is formed by a rolled sheet of sheet material, the edges of which are overlapped with each other to form flat surfaces on both sides of the base.
  • the base in the form of a flat or flat oval tube, the surface of which has an abrasive working part, allows the installation of a removable abrasive sleeve on a rigid core (for example, in the form of a flat elongated rectangular plate with rounded edges) nail care devices by sliding a flat or flat-oval tube over a rigid core along its length.
  • a rigid core for example, in the form of a flat elongated rectangular plate with rounded edges
  • the formation of a base from a rolled sheet of sheet material, the edges of which are overlapped with each other with the formation of flat surfaces on both sides of the base makes it possible to increase the tensile strength of the base, and also reduces and levels the possible error when joining the edges of the rolled base sheet, which increases the reliability the entire base and simplify its manufacture, as well as improve the reliability and safety of use of a removable abrasive sleeve mounted on a rigid core.
  • the abrasive cloth is bonded to the flat surface of the backing by an adhesive bond, thereby increasing the reliability of the connection and simplifying the manufacture of the removable abrasive sleeve.
  • the abrasive cloth is connected to the flat surface of the backing by means of a layer of resilient material, for example, ethylene vinyl acetate (EVA), adhered simultaneously to the backing surface and to the back surface of the abrasive cloth, which also increases the reliability of the connection due to the microporous structure.
  • EVA ethylene vinyl acetate
  • a cellular type of elastic material which gives better penetration of the glue, and also provides additional damping of the abrasive working surface when it comes into contact with the nail when using a nail care device with a removable abrasive sleeve, which further increases the safety of using the removable abrasive sleeve.
