[0026] These examples and images do not limit other possible embodiments of the removable abrasive sleeve according to the invention, but only explain its essence.

[0027] Removable abrasive sleeve for a nail care device (FIG. 2-4) 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.sup.2 is used for the base (1). On the surface of the cloth (3), which forms the inner surface of the base tube (1), is applied a layer of polymer coating—polyethylene. The amount of such a polymer coating of polyethylene for the cloth (3) is in the range of 8-12 g/m.sup.2. Alternatively, the base (1) can be made entirely of polyethylene.

[0028] 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. As one embodiment (FIG. 5-7), 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). 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). According to yet another embodiment (FIG. 8-10), 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). According to yet another embodiment (FIG. 11-13), 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). For these embodiments can be used an abrasive cloth (7) of the same grain size or different grain size on different flat surfaces (6) of the base (2). The thickness of the layer of elastic material (8) is in the range of 0.5-1.5 mm, for example, 1 mm.

[0029] 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. Before use, the removable abrasive sleeve is mounted on a rigid core by putting it on. During operation, 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. Then 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. In the case of using a removable abrasive sleeve with an abrasive cloth (7) located on both flat surfaces (6) of the base (2) alternately use each abrasive working part (2) or a flat surface (6) with an abrasive working part (2) of the desired grain size.

[0030] 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.

[0031] Thus, 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.
