RU69384U1 - FOOTWEAR INsole FOR SHOES - Google Patents

Abstract

An insole for shoes refers to light industry, in particular, for shoe production, and can be used in the manufacture of insoles for working, everyday, sports, medical and other types of shoes. It is made of a base in the shape of a foot of a liquid absorbent material impregnated with an antimicrobial agent, and as a base material, a liposcopic - oil absorbing material is used, and as an antimicrobial agent - vegetable oils containing volatile antimicrobial components. For the base, material of plant or synthetic origin is used, namely, woven or non-woven material made of natural fiber, natural or pressed leather, cardboard, cork, foamed plastic, and vegetable oils are chamomile, thuja, eucalyptus, orange zest, cloves or their mixture. The ratio of liposcopic base material and antimicrobial agent is in wt.%: Liposcopic base material 86-97, antimicrobial agent 3-14. The insole is placed in a sealed package of polymer film or foil and has a long and high antimicrobial effect. It is simple and inexpensive to manufacture, pleasant to wear.

Description

The inventive utility model relates to light industry, in particular, to shoe production, and can find application in the manufacture of insoles for working, everyday, sports, medical and other types of shoes.

The development of an unpleasant odor, as well as fungal diseases of the foot, is a fairly common phenomenon. To reduce the negative factor that often occurs when wearing closed shoes, there are many different special designs of insoles based on various approaches: using hydrophilic and moisture-absorbing materials, making special channels in the insole for drying and ventilating the foot, using multilayer materials, impregnating the insoles with various antimicrobial and antifungal agents, etc. See, for example, patents RU No. 2260362, publ. 09/20/05., 2254795, publ. 06.27.05., 2142246, publ. 12/10/1999., 2217026, publ. 11/27/03., US 2004244224, publ. 12/09/04. and etc.

Closest to the claimed utility model is a footbed insole according to patent RU No. 2254795 publ. 06/27/05. This insole consists of the main fabric layer of cotonized flax, which is impregnated with chitosan in the following ratio wt.%: Cotonized flax 60-80, chitosan 20-40, while the main layer is placed between the layers of cotton fabric.

For the prototype, according to most of the coinciding features, due to the fact that we are declaring the object “device”, the invention was adopted according to A.S. USSR No. 112494, declared 10.10.1956 "Textile insert insole for shoes." This insole consists of the main fabric layer of textile, impregnated with a nitrous emulsion, consisting of colloxin nitro-lacquer, castor oil and water.

The above insole has several disadvantages. As a basis, it provides for the use of only textile material, and the active, antimicrobial agent is a nitrous emulsion, including nitro-lacquer, which is toxic and harmless to the human body. The presence in the active substance of castor vegetable oil, which does not have volatile properties, does not allow to achieve an effective effect on the entire foot, including fingers, between which fungi and microbes are most spread, emitting an unpleasant odor, limiting the area of its effect mainly to the sole. In addition, castor oil does not contain aromatic substances that can drown out unpleasant odors.

The technical task of the utility model is the creation of inexpensive, effective and harmless to human insoles, with a long antimicrobial and positive deodorizing effect.

This problem is solved due to the fact that in an insert insole for shoes, consisting of a foot-shaped base made of a liposcopic plant or synthetic tissue material - textiles soaked with an antimicrobial agent containing vegetable oil, essential oils containing volatile antimicrobial components are used as vegetable oil , such as sage oil, chamomile, thuja, eucalyptus, orange peel, cloves, or a mixture thereof, and as a liposcopic base material, in addition to woven materials, there can be USE liposkopichnye and nonwoven materials of natural fibers, natural or compressed leather, cardboard, cork or

foamed plastic. The ratio of liposcopic base material and antimicrobial agent can be in wt.%: Liposcopic material 86-97, antimicrobial agent 3-14. In order to fully preserve its antimicrobial properties prior to its intended use, the insole can be placed in airtight packaging made of a polymer film or foil.

The technical result is achieved due to the fact that the antimicrobial agents proposed for impregnation of insoles have the following properties:

- chamomile and sage with a pleasant unsharp smell of wildflowers and herbs - widely known highly effective anti-inflammatory, bactericidal, antimicrobial, antiseptic agents;

- thuja has a light, "unobtrusive" smell of needles and is also an effective anti-inflammatory and antiseptic;

- eucalyptus has a strong, but not annoying, but beneficial effect on the nervous system odor and, in addition, a very highly effective anti-inflammatory, antiseptic antimicrobial agent;

- orange peel has a light, very positive reassuring odor and good deodorizing effect;

- cloves, having a pleasant and persistent floral aroma, while being a good antiseptic and antimicrobial agent, has long been widely used in medicine and perfumery.

Thus, the use of the oils of the above plants and their mixtures as an active agent provides a positive, effective and long-lasting effect of insoles. In addition, by selecting various mixtures from the above oils, it is possible to obtain composite antimicrobial agents with an original, unconventional odor and a wide range of antimicrobial and deodorizing effects. At the same time, components harmful to humans are completely absent.

The manufacturing technology of the proposed insoles is very simple.

From a liposcopic (absorbent oil) material in the shape of a foot, blanks of the required size are cut with a stamp, after which, using a manual or automatic dispenser, an antimicrobial agent from one or a mixture of several volatile oils with antimicrobial properties that apply to the entire surface of the insole. The insole is placed in a sealed material (polymer film, foil) and sealed.

Application. They open the packaging, put the insole in the closed shoes - left or right, turning the right side, and wear it.

The authors conducted the following experiments. Insoles were taken in which liposcopic (oil-absorbing) material from natural fibers: flax or catonized flax soaked with antimicrobial agents was used as the base material. As antimicrobial agents, volatile vegetable oils of sage, thuja, eucalyptus, orange peel, cloves or a mixture of them were used: clove-sage in a ratio of 1: 1, thuja-eucalyptus in a ratio of 1: 1. The test subjects were put insoles with shoes with various options for impregnation with antimicrobial substances. After 8 hours of continuous shoe wear, sterile saline was used to flush out the interdigital portions of the subjects' legs. In the washes, the content of bacteria of the genus Bacillus was determined according to the standard method, in accordance with existing identification recommendations (Identifier of the bacteria Bergey. T.1 / Edited by J.... Hoult, N. Krieg, P. Snit, S. Williams. - M. : World, 1997 .-- 432 p.). Flushing was carried out every three days for 45 days from the beginning of the use of insoles. amount

subjects for one recipe was 5 people. The experimental data demonstrating the duration of exposure (by the number of bacteria) are shown in table 1.

The table shows that the content of microorganisms, in particular the genus Bacillus, when using insoles under the effect of the proposed essential oils and their mixtures was reduced to 5-30%. In addition, the insoles, impregnated with various types of oils and their mixtures, retained their properties for quite a long time, which proves their effectiveness. The volatility of the soles proposed for impregnation of the insoles of the oils ensures the unhindered penetration of their vapors to the surface of the legs even through socks, which are also soaked in a pleasant aroma.

Thus, the proposed insoles have a long and high antimicrobial and positive deodorizing effect. When several components are used simultaneously as an active substance, there are ample opportunities for creating original odors and mutually enhancing the properties of the components. Insoles are simple and inexpensive to manufacture, pleasant to wear.
