Cobra safety razor and razor accessories for its maintenance

The utility model relates to human hygiene products, in particular, to safe shaving razors for shaving hair on a person’s skin with a mechanical wet method without first applying shaving agents to the entire surface of the skin being treated and to shaving accessories for servicing said safety razors.

Shadowless razors are known including a holder, a blade mounted in the holder, and a handle attached to the back surface of the holder. In a handle, assemblies for supplying shaving products to the cutting edges and / or skin surface in front of the blade and the razor holder are mounted in various structural designs ((US, C1, 4228587; US, C1, 4314404; US, C1, 4377034; US, C1, 4433483; US, C1, 5072512; US, C1, 5287624; US, C1, 5564190; US, C1, 2001/0003869; US, C 1, 2002/0023351; DE, C1, 19621215; GB, C1, 2141656; GB , C1, 2266854).

The disadvantage of these safety razors is the complicated design of the shaving means supply units located in the handle, as well as the excessive consumption of shaving cream (continuous application of the product on the skin or on the cutting edges of the blade).

The closest technical solution (prototype) is a shaving system containing a safety razor, including a handle and a holder connected to it with a mono or multi-edge blade mounted in the holder with the formation of through washing slots and a protective insert located along the cutting edges of the blade (US, C1, 4974319). Before shaving hair, the skin is degreased, moisturized, and the shaving process is carried out by periodically immersing the shaver holder in a ditch with a shaving aid, applying a razor with blades to the skin surface and repeatedly

moving along the specified surface, providing cutting hair. In the process of moving the razor, the shaving product is simultaneously transferred from the holder to the hairline and skin, which facilitates cutting hair.

The disadvantage of the prototype razor is the draining of the shaving agent from the holder and holding a small amount of shaving agent in the washing slots and on the surface of the razor holder when it is once immersed in the cuvette. In this regard, the inconvenience of using a razor arises from the need to repeatedly immerse its holder in a ditch with a shaving aid.

Known razor accessories, including a housing in which an internal channel is made in the form of a bell open on the side of the end face of a larger diameter, to which an elastic shaving container is coaxially attached. On the outside of this case, there is a safety razor fastening element and a working horizontal cell connected by a hole to the closed end of its inner channel (US, C1, 4858314).

The disadvantage of this shaving accessory is that it can only be used when placed in a horizontal position, which takes up a lot of space, and the part of the shaving agent that fills the internal channel of the housing is not used and is lost when washing the shaving accessory while changing the container with the shaving aid .

The closest analogue to the prototype device is a razor accessory, including a container, a lid and a tapered transverse partition with an opening in the top of the cone, located inside the container with the formation of a working cell located on the side of the lid and an open cavity located on the other side. An aerosol container with a means for

shaving under pressure, the spray head of which is placed in the hole of the conical transverse septum (US, C1, 5141349).

The disadvantages of the specified shaving accessories (prototype) is the ability to use shaving only in aerosol cans under pressure.

The technical result of the proposed utility model is the creation of:

- such a safe razor, which allows for a single immersion of its holder in a cuvette with a shaving aid to carry out the entire shaving cycle;

- such a compact razor accessory, which provides a dosed supply of shaving products into the cuvette without significant losses.

The specified technical result is achieved by the fact that in a safety razor including a handle and holder with a mono or multi-edge blade installed in the holder with the formation of through washing slots and a protective insert made along the cutting edges of the blade, according to a utility model, it is equipped with a storage container for shaving and a flat element for flowing the shaving means from the blade holder to the storage tank and vice versa, having wide and narrow mating parts. For example, a flat element can be made in the form of a trapezoidal plate. The end of the wide part of the flat element corresponds to the length of the holder and is attached to its rear side along the protective insert, the end of the narrow part of the flat element corresponds to the diameter of the handle and is attached to one of its ends, and the storage tank is installed with the neck in the direction of the holder around the flat element at the place of its attachment to the pen.

protrusions and depressions and is made curved towards the back of the blade holder.

Such a structural embodiment of the razor provides a smooth slow flow of the shaving product on the surface of the flat element from the blade holder to the storage tank and vice versa, which prevents the product from draining from the razor. The flat element and the capacitive storage allow for a single immersion of the holder in a cuvette with a shaving aid to ensure a full shaving cycle.

A perforated or comb plate is attached to the back of the holder along its line of connection with the flat member to form a collection pocket for the shaving aid. The collection pocket increases the amount of shaving aid that is captured when the holder is immersed in the cuvette, and also adjusts the dosed supply of the shaving aid to the edges of the safety razor blade.

The specified technical result can also be achieved by the fact that in a razor blade including a container with a shaving aid, a lid and a tapered transverse partition with an opening at the top of the cone, located inside the container with a shaving aid with the formation of a working cuvette located on the side of the lid and cavity with shaving means located on the side of the bottom of the container, according to a utility model, it is provided with a tube installed in a cavity with shaving means, one end of which is attached to the transverse minutes conical wall coaxially to its opening and the other end is placed at the bottom of the container with a shaving aid, and, in the conical partition docking location with the vessel wall in the conical wall or in the wall of the vessel, a check valve or an opening for pressure equalization.

In addition, the shaving accessory is equipped with a plug placed in the working cell coaxially to the tube and the lid and attached at one end to the lid or is made integral with it and the other end

placed in the inlet of the tube. The plug prevents the shaving product from escaping during shaving.

In addition, the inner channel of the tube is made tapering from the end attached to the transverse conical septum to the end located at the bottom of the container with a means for shaving. This embodiment of the channel provides a decrease in the speed of movement of the shaving means in the process of using shaving accessories.

Utility Model Description

The safety razor comprises a handle 1, a holder 2 with a mono or multi-edged blade 3 installed in the holder 2 with the formation of through washing holes 4 and a protective insert 5 made along the cutting edges of the blade 3. In addition, the razor has a shaving cap 6 and a flat element 7 for flowing shaving products from the holder 2 into the storage tank 6 and vice versa, having a wide 8 and a narrow 9 mating parts. For example, a flat element can be made in the form of a trapezoidal plate. The end of the wide part 8 of the flat element 7 corresponds to the length of the holder 2 and is attached to its rear side 10 along the protective insert 5. The end of the narrow part 9 of the flat element 7 corresponds

the diameter of the handle 1 and is attached to one of its coits, and the storage tank 6 is installed with the neck 11 in the direction of the holder 2 around the flat element 7 at the place of its attachment to the handle 1. Inside the storage tank 6, radial partitions 12 can be installed. The flat element 7 has corrugated surface with protrusions 13 and depressions 14 and is made curved towards the back side 10 of the blade holder 2. On the back side 10 of the holder 2, along the line of its connection with the flat element 7, a perforated plate 15 is attached to form a collection pocket for the shaving aid.

The shaving accessory contains a container 16, a cover 17 and a conical transverse partition 18 with an opening at the top of its cone, located inside the container 16 with the formation of a working cell 19 located on the side of the cover 17 and cavity 20 with a shaving means located on the bottom side of the container 21. A tube 22 is installed in the cavity 20 with the shaving means, one end of which is attached to the transverse conical septum 18 coaxially with its opening, and the other end is located at the bottom 21 of the shaving container. At the junction of the conical septum 18 with the wall of the container 16 in the conical partition 18 (Fig. 6) or in the wall of the tank 16 (Fig. 7), a check valve 23 is installed or a hole 23 is made for pressure equalization instead. In the event that a hole is made instead of valve 23, then it should be no larger than 500 microns in size.

In addition, the razor accessory is equipped with a plug 24, placed in the working cell 19 coaxially to the tube 22 and the cover 17 and attached end to the cover 17 or made integral with it. Another opposite end face of the plug 24 is placed in the inlet of the tube 22. The inner channel of the tube 22 is made tapering from the end attached to the transverse conical wall 18 to the end located at the bottom 21 of the shaving container.

Using a safety razor and razor accessories is as follows. The shaving agent, which is used as a shampoo, or liquid soap, or other foaming agent with dynamic viscosity, for example, no more than 10 Pa sec, is placed in the cavity 20 of the shaving container 16. The cap 24, when the lid 17 is closed, prevents the shaving agent from flowing out of the container 16 during storage and transportation of the shaving accessories. Before shaving, open the shaving cap 17 and press on the walls of the container 16. Due to the increased pressure in the cavity 20 of the container 16, the dose of the shaving agent passes through the tube 22 into the cavity of the working cell 19. The razor is lowered into the working cell 19 of the container 16 with the holder 2 immersed and partially flat element 7 in a layer of shaving products. In this case, the shaving agent is applied on the surface of the holder 2 and the flat element 7, on the cutting edges of the blade 3, penetrates into the washing holes 4 of the holder 2 and is held there due to viscosity. After the cessation of pressure on the walls of the container 16, the latter acquires its original shape and the remnants of the shaving agent flow through the tube 22 into the cavity 20 of the container 16 due to the occurrence of reduced pressure in it. A check valve or hole 23 smoothes out the pressure pulsations in the container 16, which enhances the usability of the device.

After that, before shaving (depending on the situation where the person is: at home, or in traveling conditions in nature, or on a train during a long trip), the face and hair on it are degreased by washing it with detergents and water (without drying the skin, for example towel). Next, the razor holder 2 with the cutting edges of the blade 3 is applied to the wet surface of the skin, followed by repeated movement of the razor along the surface of the skin of the face, during which the said shaving agent is transferred to the treated area of the skin from the razor blade 3 to form

a microlayer of foam and simultaneous cutting of hair with the cutting edges of the blade 3. To ensure high-quality shaving, the razor is first moved in the direction of hair growth (in the forward direction), and then against the growth of hair (in the opposite direction). When shaving hair in the direction of their growth, the razor holder 2 is located in the upper position, and its handle 1 is in the lower vertical position, as a result of which part of the shaving agent gradually flows from the surface of the holder and the surface of the flat element 7 into the storage tank 6. When shaving against growth hair holder 2 is in the lower position, and the handle 1 is in the upper vertical position. In this case, the shaving agent gradually flows from the storage tank 6 along the flat element 7 to the cutting edges of the blade 3 of the razor holder 2. The radial partitions 12 slow down the process of moving the shaving product from the reservoir 6, and the protrusions 13 and troughs 14 of the corrugated surface slow down the movement of this tool on the flat element 7, as a result of which a continuous, controlled process of supplying the foam detergent to the blade 3 is ensured during the entire shaving cycle. In addition, the radial partitions 12 prevent spraying or spilling of the foaming agent when shaving when the handle 1 is in the upper vertical position. The structural embodiment of the flat element 7, for example, in the form of a trapezoidal plate also eliminates the spraying or spilling of the product during shaving.

A complete shaving cycle is carried out without washing the holder 2 and the cutting edges of the razor blade 3. The preliminary degreasing of the skin and hair ensures unhindered penetration of the shaving product (soap, shampoo) to the surface of the hair, which contributes to their adsorption reduction in strength under the influence of surface-active substances (surfactants) in accordance with the Rebinder effect (D.A. Friedrichsberg. Course of colloid chemistry .- Leningrad, publishing house Chemistry,

1974.- p. 279-280) .. Moisturizing the skin and hair with water before shaving contributes to a more efficient formation during the shaving process of a microlayer of foam on the cutting edge of the blade and the area of hair subjected to cutting by the cutting edge of the blade.

Shaving a face is recommended daily or after 1-2 days, depending on the individual characteristics of the skin and the growth rate of human hair.

The utility model relating to safety razors and shaving accessories can be implemented both in large cosmetic companies and in small businesses using modern materials and technologies.
