Description

The utility model relates to manicure and pedicure accessories, namely to electromechanical devices for hardware manicure and pedicure, the so-called. for milling cutters, in which removable nozzles or cutters are used as a working body for grinding both the nail itself and the skin around it. On the outer surfaces of such removable nozzles, which, as a rule, are in the form of a disk, replaceable pads with an external abrasive surface are glued, which act as a working surface for a nozzle for cutting off dead or hardened tissue from the surface of human skin. The declared useful model also concerns the design of such removable linings.

There are many similar replaceable pads that are used to cut off dead or hardened tissue from the surface of human skin, among which the closest is the next one chosen for the prototype. This is a replaceable attachment for the manicure and pedicure apparatus described in patent UA141238, published 03/25/2020. Replaceable pad according to the prototype contains a working surface and an adhesive surface. The working surface is formed by a layer of abrasive material with an outer granular surface. The adhesive surface is formed by a layer of adhesive material with an outer adhesive surface connected to the layer of abrasive material on the side opposite to the outer granular surface. In this case, the nozzle is made of a flat and round shape with continuous layers of abrasive material and adhesive material, that is, it is intended for nozzles that have a flat outer (working) surface. When using such an overlay for a convex nozzle, that is, with a spherical outer surface, peeling, swelling or skewing of the overlay is possible due to its poor mating with the convex surface of the nozzle and insufficient fixation of the adhesive surface of the overlay on it. The convex surface of the nozzle has its advantages in processing, in particular, it allows processing without an angle of inclination of the handle of the manicure and pedicure apparatus.

The utility model is based on the task of creating a replaceable overlay on a convex nozzle for a manicure and pedicure apparatus, which ensures reliable fixation on the surface of the nozzle by changing the design of the overlay.

The problem is solved by the fact that a replaceable pad for a nozzle for a manicure and pedicure apparatus, containing a working surface formed by a layer of abrasive material with an outer granular surface, and an adhesive surface formed by a layer of adhesive material with an external sticky surface connected to the abrasive material from the side , opposite the outer granular surface, according to the invention, contains a cutout in the peripheral part of the abrasive material layer and the adhesive material layer. This cutout prevents the pad from peeling off the nozzle and its distortion or swelling due to guaranteed contact of the nozzle with the pad over its entire adhesive surface and increases the reliability of fixing the removable pad.

According to one of the preferred embodiments of the utility model, the removable patch is made in the shape of a circle, which is the optimal shape for treating the surface of the human skin when the attachment is rotated. In this case, the cutout can be located radially to the center of the circle of the lining and is made in the form of a sector of a circle with a center that coincides with the center of the circle of the lining, which additionally increases the reliability of fixing the removable lining and its coverage of the entire convex surface of the nozzle by closing the edges of the cutout when the lining is glued onto a convex surface. According to another possible embodiment of a removable patch in the shape of a circle, it may comprise a plurality of cutouts in the peripheral part of the abrasive layer and the adhesive layer, located at the same pitch along the diameter of the circle, which also improves the contact of the patch with the convex surface, and also further reduces the speed clogging the layer of abrasive material of the working surface of the lining with the cut material due to its more intensive removal through the specified set of notches, which improves the quality of the leather surface treatment and the service life of the lining.

The following is an example of the implementation of a removable patch according to the invention and its connection with the working surface of the attachment for the manicure and pedicure apparatus, illustrated by the following images: FIG. 1 is a side view of a removable pad; fig. 2 is a front view of a replaceable patch according to one of its variants; fig. 3 is a front view of a replacement patch according to another embodiment thereof; fig. 4 is a front view of a replacement patch according to another embodiment thereof. The examples given and the images provided do not limit other possible options for performing the replaceable patch, according to the utility model, but only explain its essence and confirm the possibility of its implementation.

FIG. 1-4, the following notation is used:

1 - work surface,

2 - adhesive surface,

3 - a layer of abrasive material,

4 - a layer of adhesive material,

5 - protective layer,

6 - cut

7 - central hole.

A replaceable pad for a nozzle for a manicure and pedicure apparatus has a round shape and contains a working surface (1) and an opposite adhesive surface (2). The working surface (1) is formed by a layer of abrasive material (3) with an outer granular surface. The layer of abrasive material (3) can be made of an abrasive cloth made of silicon carbide applied to a paper base with latex impregnation. The adhesive surface (2) is formed by a layer of adhesive material (4) with an external adhesive surface, connected to the layer of abrasive material (3) on the side opposite to the external granular surface. The outer sticky surface is covered with a protective layer (5) with the possibility of separating it from the outer sticky surface. The layer of adhesive material (4) can be made of double-sided adhesive tape or adhesive multicomponent composition based on organic or inorganic substances, connected on one side with a layer of abrasive material (3) and on the other side with a protective layer (5). The protective layer (5) can be made of paper.

In the peripheral part of the layer of abrasive material and the layer of adhesive material, a cutout (6) is made, located radially to the center of the pad circle and made in the form of a sector of a circle with a center that coincides with the center of the pad circle (Fig. 2). According to the embodiment (Fig. 2), the replaceable pad contains a set of cutouts (6) in the peripheral part of the abrasive material layer and the adhesive material layer, located at the same pitch along the diameter of the circle. In this case, such a patch may contain a central hole (7) made simultaneously in the layer of abrasive material (3) and the layer of adhesive material (4) in the form of a circle, the center of which coincides with the center of the circle of the patch. The central opening (7) can also be provided with a removable cover shown in FIG. 2. Such an embodiment is shown in FIG. 4. The central hole (7) is necessary to prevent the nozzle from slipping when it is rotated during the processing of the leather surface and to increase the safety of processing.

Use a removable pad, according to the utility model, as follows. First, the protective layer (5) is removed from the outer sticky surface of the adhesive layer (2), after which the outer sticky surface is connected to the outer surface of the disc-shaped attachment for the manicure and pedicure apparatus in such a way that the outer granular surface of the abrasive material layer (3) located outward. Then the apparatus is turned on, after which the rotation of the nozzle disk begins. By contacting the working surface (1) of the removable pad, which rotates with the attachment, dead or hardened tissue is removed from the nail or skin in the area of the human nail. At the same time, in the presence of a cutout (6) or a set of cutouts (6), they provide contact of the entire adhesive surface (2) with the convex surface of the nozzle and thereby prevent the lining from peeling off, its skewing and insufficient fixation on the outer surface of the nozzle of the apparatus. When the outer granular surface of the abrasive material layer (3) is developed, the replaceable pad is separated from the outer surface of the nozzle and replaced with another similar pad.

Thus, thanks to the use of the utility model, a reliable fixation of the patch on the surface of the attachment during the processing of the surface of the human skin is ensured.
