Description

Technical field

The inventive utility model relates to manual cutting devices with several cutting edges, in particular to safety razors intended for human hygiene, namely for shaving hair on the skin.

State of the art

A safety razor is known which comprises a handle, a holder with a blade fixed therein and a security element. The blade holder is connected to the handle via two hinges. The hinges are made of spring wire. The protective element is made in the form of a damping bracket. It is located in front of the blade and connected to the handle with the possibility of damping. The blade holder is removable and connected to the hinges by a snap mechanism. (Application for invention RU 98115312 IPC B26B21 / 30, published on July 20, 2000).

A disadvantage of the known safety razor is its low hygiene characteristics.

Known safety razor made in the form of interconnected holder and handle, the holder of which contains at least one mono-or multi-edge blade, a cavity under it, provided with holes communicating with the upper side of the holder, and the surface surrounding the blade and in contact with the skin, and the holder includes elements of elastic and easily deformable material, while the holder is pivotally connected to it and covering at least its front part of the bracket with which are made of the elastic material of the cavity wall, forming one with the edging of easily deformable material, covering the surface of the holder in contact with the skin and protruding above it, at least the front part of which is fixed on a bracket having at least two fixed positions, while the cavity is made with holes in front of the blade and connected through a channel in the handle with a hollow elastic container attached to the handle, with the possibility of creating a vacuum or an air stream during its deformation (Patent RU 5550, IPC V26V21 / 00, It publishes 16.12.1997).

A disadvantage of the known device is the low hygiene characteristics.

The objective of this utility model is to expand the range of simple devices with high hygienic characteristics.

Utility Model Disclosure

The technical result of the utility model is the creation of a device with high hygienic characteristics.

The present technical result is achieved in a safety razor device containing a handle, a holder connected to the handle, in which the blade, hinge and protective element are fixed, the handle and holder made of impact-resistant, hypoallergenic heat-resistant polyester - Tritan, the blade and protective element are made of antibacterial material - Titanium, an oval shaped hole is located on the bottom of the handle.

Distinctive features are:

the handle and holder are made of impact-resistant, hypoallergenic heat-resistant polyester - Tritan, which allows the safe use of a device in contact with high-temperature media [3];

the blade and the protective element are made of an antibacterial material - Titanium, which has hygienic characteristics;

on the bottom of the handle there is an oval-shaped hole that allows you to more safely store devices on a hook in the toilet room, with minimal contact of other objects.

Comparison of the proposed solution with an analogue and prototype did not allow us to identify in them the features that distinguish the claimed solution, which allows us to conclude that the criterion of "novelty".

Brief Description of the Drawings

The figure shows a safety razor, where the numbers indicate

1. Handle containing a hole for easy storage.

2. Holder equipped with a blade.

3. The protective element.

4. The hinge.

5. The mechanism for fixing the blade.

Utility Model Implementation

The handle 1 and the holder 2 of the safety razor are performed on titanium injection molding equipment. A razor blade is made by passing a strip material - Titanium, between the rolls that touch and reduce the thickness of the strip material - Titanium. The blades for a long time remain sharp and do not rust, they have flexibility, light weight and antibacterial properties. The strength of the blades is achieved by high-temperature firing of the material. [4]

The handle 1 containing the hole is connected to a holder 2 equipped with a blade (not shown in the figure) and a protective element 3 made of titanium material in the form of a bracket and located in front of the blade mounted in the holder 2. The protective element 3, made in the form of a damping bracket, connected to the handle 1 with the possibility of damping forces. The holder 2 of the blade is connected to the handle 1 by means of hinges 4. In this case, the holder 2 of the blade is fixed to the hinges 4 by the locking mechanism of the blade 5 with the possibility of latching and replacement with a new one. The protective element 3 (damping bracket) is made in the form of a triangle, the base of which is located on the side of the blade holder 2, and the ends of the sides of the triangle are bent at an angle and fixed in the handle 1.

A safety razor is used as follows.

For shaving, you need a shaving brush, cream, foam or shaving gel (hereinafter cream). The brush is moistened with hot water, depending on the individual sensitivity of the human skin. With excess water, shake it off with a shaving brush. Then shaving cream is applied to it. Then apply the cream to parts of the face with overgrown bristles. Previously, the holder 2 is equipped with a blade and, by means of a latching locking mechanism of the blade 5, is connected to the hinges 4. Holding the safety razor by the handle 1, bring it to the face treated with the cream. The protective element 3 (the damping bracket) is in contact with the skin area first, and then, at an angle of about 30 degrees, the blade is fixed on its holder 2. The protective element 3 creates a damping force when touched, which is transmitted through the hinges 4 to the blade holder 2. Then, using the handle 1, is carried out several times by the protective element 3 and the blade of the holder 2 from top to bottom, until the skin becomes perfectly smooth. The blade in the holder 2 and the protective element 3, made in the form of a bracket and located in front of the blade of the holder 2, in use exert unequal pressure on the skin and bristles. The security element 2 exerts more pressure than the blade. The shaving process is repeated similarly with an unused blade, which in an unused holder is pre-mounted on hinges 4, the fastening is carried out by a snap mechanism for fixing the blade 5.

The proposed safety razor, which has high hygienic characteristics, allows you to expand the range of simple inexpensive devices, increase the life of the razor through the use of environmentally friendly, shockproof, heat-resistant polyester - Tritan, and will allow you to more safely store this razor due to the hole on the bottom of the handle, as well reduce the risk of skin irritation through the use of an antibacterial material - Titanium.
