Definitions

  • the invention is related to manicure or pedicure accessories, namely to nail care devices, such as hand nail files.
  • the disadvantage of such an abrasive element is the lack of reliability of its fixation on the working plate only by means of an adhesive layer applied to one side of the abrasive element, and the possibility of shifting of the abrasive element during operation due to lack of 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, which, in turn, will complicate the peeling of the abrasive element when replacing it.
  • the prototype is a removable abrasive sleeve of the device for nail care, described in UA Patent 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 tube of the base, followed by its removal after wear of the abrasive working part and replacement with a new abrasive sleeve.
  • the abrasive working part is made in the form of an abrasive cloth mounted 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, when it breaks, which reduces the reliability of the removable abrasive sleeve and the possibility of injury to the treated nail surface. Bonding of the abrasive cloth over the entire surface of the base, especially in the rounded flat or flat-oval tube, as well as the lack of damping of the abrasive working part of the nail care device in the design of the prototype can lead to the reduction of reliability and safety of the removable abrasive sleeve.
  • the invention is based on the increasing the reliability and safety of use of the removable abrasive sleeve of the device by increasing the strength of the base and the reliability of the bonding of the abrasive cloth with the surface of the base.
  • the abrasive working part is formed by an abrasive cloth bonded to the flat surface, where the base is formed by a folded cloth of sheet material, the edges of which are fastened together overlapping 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) of the nail care device by wearing a flat or flat-oval 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 the abrasive working part of the abrasive cloth bonded to the flat surface of the base allows increasing the reliability of the bonding of the abrasive cloth to the surface of the base due to their contact on a flat surface over its entire area.
  • the formation of the base of the rolled cloth of sheet material allows to increase the tensile strength of the base, and reduces and eliminates possible error when connecting the edges of the rolled base cloth, which increase the reliability of 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 base with an adhesive, which increases the reliability of the connection and simplifies the manufacture of a removable abrasive sleeve.
  • the abrasive cloth is bonded to the flat surface of the substrate by a layer of elastic material, such as ethylene vinyl acetate (EVA), glued simultaneously to the surface of the substrate and the reverse surface of the abrasive cloth, which also increases the reliability of the microporous structure of the cell type elastic material, which gives better penetration of the adhesive, as well as provide additional damping of the abrasive work surface in contact with the nail when using a nail care device with a removable abrasive sleeve, which further increases the safety of the removable abrasive sleeve.
  • EVA ethylene vinyl acetate
  • the abrasive cloth is bonded to the flat surface of the base and additionally bonded to the opposite flat surface of the base, which increases the durability of the removable abrasive sleeve by using both sides of the base when operating the nail care device.
  • the cloth made of cellulose material is used for a base.
  • the inner surface of the base tube is coated with a layer of polymer coating made of polyethylene, applied in an amount 8-12 g/m 2 at a density cellulose material cloth within 40-60 g/m 2 .
  • This further improves the reliability of fixing the base on the metal rigid core of the nail care device by contacting the polymer coating of the inner surface of the base with the metal surface of the core and thereby preventing the base from slipping out of the nail care device.
  • the layer of polymer coating of polyethylene in the amount of 8-12 g/m 2 at a density of cellulose material cloth within 40-60 g/m 2 allows to provide the necessary reliability of fixing of a removable abrasive sleeve as well as the easy removal of used sleeve from a core by its rupture.
  • the thickness of the abrasive cloth should be at least 0.2 mm.
  • abrasive cloth with a thickness of less than 0.2 mm can lead to accidental damage from a relatively small effort, for example, when wearing a removable abrasive sleeve on the rigid core of the nail care device.
  • Removable abrasive sleeve for a nail care device contains a base (1) in the form of a flat or flat-oval tube, the surface of which has an abrasive working part (2).
  • the base (1) is formed by a folded cloth (3) of sheet material, the edges of which (4) and (5) are fastened together to form flat surfaces (6) on both sides of the base (1).
  • the cellulose material cloth (3) such as kraft paper with a density in the range of 40-60 g/m 2 is used for the base (1).
  • the amount of such a polymer coating of polyethylene for the cloth (3) is in the range of 8-12 g/m 2 .
  • the base (1) can be made entirely of polyethylene.
  • the abrasive working part (2) is formed by an abrasive cloth (7) bonded to the flat surface (6) of the base (2) by an adhesive.
  • the thickness of the abrasive cloth is 0.2 mm.
  • the abrasive cloth (7) is bonded to the flat surface (6) of the base (2) by a layer of elastic material (8), for example, ethylene vinyl acetate (EVA).
  • EVA ethylene vinyl acetate
  • the layer of elastic material (8) is glued simultaneously to the surface of the base (1) and to the reverse surface of the abrasive cloth (7).
  • the abrasive cloth (7) is bonded to the flat surface (6) of the base (2) and additionally bonded to the opposite flat surface (6) of the base (2).
  • the abrasive cloth (7) is bonded to the flat surface (6) of the base (2) by a layer of elastic material (8) and additionally bonded to the opposite flat surface (6) of the base (2) also by a layer of elastic material (8).
  • the thickness of the layer of elastic material (8) is in the range of 0.5-1.5 mm, for example, 1 mm.
  • the above-described removable abrasive sleeve mounted on the rigid core of the nail care device (not shown in the figures, but it is clear that it may be in the form of a flat metal work plate with rounded edges, or a plate of rectangular or other cross section) can be used as manicure or pedicure tool.
  • the removable abrasive sleeve is mounted on a rigid core by putting it on.
  • the sleeve is held on a rigid core without additional mechanical fastening or other means, such as adhesive bonding and the like.
  • This fixation of the sleeve to the nail care device is achieved due to the tight fit of the base (1) on the rigid core. This ensures easy and free installation of the sleeve without excessive effort.
  • the flat surface (6) of the base (2) with the abrasive cloth (7) is placed parallel to the surface of the nail and nail care is performed by contact of the abrasive working part (2) with the nail.
  • the layer of elastic material (8) when used allows softening the contact of the abrasive working part (2) with the nail and increasing the safety and convenience of working with the device for nail care. Removal of the removable abrasive sleeve is carried out by tearing (rupturing) the base cloth (1) by applying a certain force to it.
  • Such a removable abrasive sleeve can be made of a certain length, the size of the rigid core of the device for nail care, or in the form of a roll containing parts divided by the weakened areas of material, obtaining after the torn off a removable abrasive sleeve of the desired length.
  • the claimed the invention provides an increase in the strength of the base and the reliability of the bonding of the abrasive cloth to the surface of the base.
