Description

Hygienic foot pad of daily use

The present invention relates to a disposable foot sanitary pad, more specifically, to include antibacterial, deodorant, fragrance in order to absorb the sweat generated in the foot when the shoes are worn and to eliminate the cause of foot odor. The present invention also relates to a disposable foot sanitary pad that is removed after use once for hygiene and convenience.

In general, sanitary pads are used in various ways to remove secretions and odors generated in the human body. The secretions produced by the human body are large, urine, women's menstrual blood, cold discharge before and after menstruation, etc. These secretions are treated using various diapers, sanitary napkins, panty liners and the like. Sweat secreted from sweat glands is weaker than other secretions, so there is no special device for treating them, but recently, axillary sweat absorbing pads have been produced to prevent odor caused by sweat and promote cleanliness.

By nature, sweat is mostly acidic water, and itself does not smell or odor, but odor occurs because anaerobic diphtheria bacteria act to produce an unpleasant odor. In particular, when the shoes are worn, the feet are kept in a closed state so that a lot of sweating is provided, and in such a situation, optimum conditions for germs to grow are provided. In addition, sweating between shoes, socks, and toes causes the stratum corneum, the outermost layer of skin, to blow, and bacteria break down sweaty keratin, creating an odorous chemical called isovaleric acid.

Devices for removing the sweat generated from the foot when wearing shoes include socks, shoe insoles, disposable shoe insoles, etc. These include a number of problems that do not completely remove the odor caused by sweat. In socks, cotton socks provide comfort with excellent sweat absorbing ability, but when worn for a long time, they become wet due to excessive sweating, and have only a moisture absorbing function, but have no function of preventing bacteria generation. In particular, nylon stockings, which are mainly used by women, do not absorb sweat at all, and the smell of feet caused by them is a big concern. In addition, the existing shoe insole has a disadvantage in that the sweat absorbing ability is somewhat lower than the socks, and there is no separate device for preventing the growth of bacteria, and contaminants accumulate when not washed for a long period of time due to the hassle of washing frequently. Recently, a disposable shoe insole with antibacterial agent and fragrance added to the absorbent pad has been filed for <Registration Utility Model 20-0308056>. However, this method does not include deodorant and uses only a fragrance to mask the foot odor. There is this. This problem is not solved by simply adding a deodorant to the absorbent pad containing the antimicrobial and fragrance. This is because it cannot be overlooked that there is a possibility that the functions of each other will be canceled out when the deodorant having the property of adsorption and the fragrance having the property of emitting fragrance are used together. Therefore, in order to eliminate the cause of foot odor caused by sweating when wearing shoes, it is necessary to remove moisture, which accounts for most of the components of sweat, to suppress the production of bacteria, and to add deodorants and fragrances, but to cancel each other's functions. A separate device is needed to minimize it.

The present invention is to solve the above problems, in order to remove the cause of foot odor due to sweat generated in the foot when wearing shoes, including an antimicrobial agent, deodorant, fragrance in the integrated absorbent pad and used once without the need for separate washing The purpose is to provide a disposable foot sanitary pad to remove after.

The technical problem to be achieved by the present invention to achieve the above object is as follows.

First, it constitutes an aspect of a disposable absorbent pad that is appropriately arranged in each of the inner sheets constituting the integral absorbent pad, absorbent or absorbent, antibacterial, deodorant, fragrance and can be inserted, detachable on the existing shoe insole.

Second, in order to minimize the trade-off between each other due to the inherent characteristics of the deodorant and the fragrance, the area of the absorbent pad is divided and the deodorant and the fragrance are separately disposed in each area.

Third, in order to prevent the deodorant and the fragrance from moving and being mixed with each other in the area division of the integrated absorbent pad, a method of connecting the area division surfaces is devised.

The present invention for achieving the above object relates to a disposable foot sanitary pad for absorbing the sweat generated in the foot when wearing shoes and to eliminate the cause of foot odor caused by sweat.

As used herein, the term 'absorbent product' refers to a device that absorbs and retains human secretions, and more specifically, a device that is disposed opposite to or close to the wearer's body to absorb and retain various secretions secreted by the human body. Say. The term 'disposable' as used herein is intended to describe an absorbent product intended for disposal after one use, preferably for recycling, composting or disposal in an environmentally suitable manner. An 'integral' absorbent product refers to an absorbent product in which the individual parts are integrated with each other to form a combined finished product that does not require separate operating parts. Therefore, the integrated absorbent product described in the present invention is an absorbent product that is worn adjacent to the body for the purpose of absorbing and absorbing body secretions, ie, sanitary napkins, panty liners, diaper or incontinence pads, armpit sweat absorbing pads, sweat absorbing shoes. Of course, it can also be applied to other absorbent products such as insoles or absorbent products for pet food treatment.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the drawings.

<1> Structure of each layer of integrated absorbent pad

The integrated absorbent pad of the present invention is a liquid or moisture permeable top sheet 21, a liquid impermeable back sheet 24 connected to the top sheet 21, a top sheet 21 and a back sheet 24 as shown in FIG. It consists of the inner sheet 22 which functions in deodorization and aroma, and the absorption sheet 23 which functions in absorption or moisture absorption and antibacterial.

The top sheet 21 is non-irritating to the wearer's skin. It is also liquid, moisture permeable and penetrates well through its thickness. Suitable topsheets 21 may be made from woven and nonwoven materials made of perforated films, foams or natural or synthetic fibers.

The backsheet 24 is connected to the topsheet 21 and is preferably made from a liquid impermeable and thin plastic film, but other flexible liquid impermeable materials may also be used. The backsheet 24 has surfaces on the inside and outside of the pads, the surfaces outside the pads including an adhesive material 25 to adhere to the insole of the shoe so as to adhere onto the existing shoe insole.

The absorbent sheet 23 is located between the top sheet 21 and the back sheet 24, and includes an antimicrobial agent for suppressing bacterial growth in absorbents conventional for various absorbent products. The absorbent body can be any absorbing means that absorbs liquid or moisture, and can be of various sizes and shapes. However, in order to solve the dullness, tightening, and pressure feeling that may be felt when the pad is worn in the shoe, it is preferable to use an ultra-thin and lightweight absorbent. Since sweat is discharged from person to person, sweat is discharged in the form of moisture and in the form of flowing liquid. Therefore, in addition to the superabsorbent resin, the absorbent included in the absorbent may be silica, chloride-based absorbent and the like.

The inner sheet 22 is preferably located between the top sheet 21 and the absorbent sheet 23, and may be made of the same tissue material as that used for the pulp or absorbent body common to various absorbent articles. If necessary, the inner sheet 22 is configured to have a lower density than the absorbent sheet 23 so that sweat can be absorbed quickly. The inner sheet 22 preferably includes a deodorant for adsorbing malodors and a fragrance for providing a predetermined scent. However, when the deodorant and the fragrance are used together, there is a possibility that the functions of each other are canceled. Therefore, it is preferable to divide the regions in the pad and disperse them in the appropriate regions in consideration of the characteristics of each component.

Hereinafter, one preferred embodiment of the area division of the present invention will be described in detail with reference to the drawings.

<2> zone segmentation

In order to properly divide the deodorant and the fragrance into the region in which the inner sheet 22 is distributed, the characteristics of each material are as follows.

A fragrance is a product made by adding fragrance or strong scented organic substance to provide a fragrance. It is generally used for the purpose of concealing odors or reducing odors or unpleasant odors in homes, enclosed spaces and everyday living spaces. do. The material used here is highly volatile at room temperature and is an intense aromatic substance that is spread out into the air by diffusion.

Deodorants are products used for the purpose of reducing or eliminating odor-causing substances or treating them after they have occurred. Deodorization methods up to now can be divided into sensory deodorization, physical deodorization, chemical deodorization, and biological deodorization. All methods are based on deodorization technology except for sensory deodorization which conceals and neutralizes bad smell sources. Basically.

Mechanism of Deodorization Technology

Contact between pollutant (odor source) and deodorant material → decomposition, adsorption (neutralization, oxidation, reduction, etc.) → removal of odor-causing substances → clean air

Therefore, the main points in the area division of the inner sheet 22 in consideration of the respective characteristics are as follows.

First, fragrances need space to emit fragrance.

Second, it is preferable to place the deodorant at a close distance so as to make contact with the bad smell source more efficient.

Among the representative deodorants, activated carbon is easily found in daily life. Deodorization method of activated carbon is an adsorption method in which odor molecules are physically adsorbed onto a porous material and deodorized. In general, adsorption refers to a phenomenon in which a substance is concentrated on a solid or liquid surface. In the case of physical adsorption, the attraction of molecules between an adsorbent and a substance causes the substance to adhere to the adsorbent surface. This attraction acts in the form of chemical bonding force not only in the adsorption mechanism but also in the neutralization, oxidation, and reduction mechanisms to induce and form the combination of the deodorant and the malodor source. The attraction that induces this bond is a function of the distance inversely proportional to the square of the distance between the two materials, so the closer the distance between the two materials, the greater the attraction.

In order to apply the above point, the anatomical structure of the foot is examined and the contact surface of the pad and the foot is considered.

The human foot is the only foot that has an arch. The arch is responsible for shock absorption when standing, walking or running. Human feet with arches are divided into those that touch the floor and those that do not touch the skeleton. The parts other than the arch touch the floor to support the weight, and the arch forms extra space.

Therefore, the shorter the contact distance to the bad smell source, the greater the efficiency of the deodorant, which is preferably disposed separately in the portion other than the arch, that is, the portion 12 where the foot is in contact with the pad, and provides a space for emitting fragrance. The necessary fragrance is preferably placed in the part 11 where the arch of the foot is located in the pad. In addition, the fragrance may be disposed on the upper part of the end of the toe, that is, the part 11 where extra space may be left in front of the toe when the shoes are worn.

<3> Concatenation treatment of area division surface

In order to prevent the deodorant and the fragrance from moving and mixing with each other after arranging the materials according to their characteristics, an appropriate method of conjoint treatment of the divided area of the foot divided into parts where the foot touches the pad is required. For this purpose, a close joint is formed by attaching and sealing each sheet of the pad through a predetermined pattern or stitching along a line dividing the region. This is to ensure that each of the included materials functions more effectively and minimizes the surface area in contact with each other. If desired, several layers of stitches or stitches may be used to form barriers that impede the movement of the material.

Each sheet can be fixed in place with a predetermined adhesive as needed. Materials included in each sheet may be different in the stacking order and arrangement, if necessary, in addition to any of the materials having the characteristics required by the present invention as described above. The shape of the pad may be configured in various forms (for example, a pad shape using only the front of the foot) according to the shoes to be worn, and the color of the pad may also be configured in various ways according to the shoes to be worn. It is apparent that many other arrangements, combinations, and variations are possible.

As described above, the disposable foot sanitary pad according to the present invention has the following advantages.

1. Removes moisture by absorbing sweat from feet when wearing shoes.

2. Suppresses the growth of bacteria that cause foot odor.

3. Eliminate foot odor caused by sweating.

4. Provide the desired scent.

5. Minimize deodorization and offsetting of odor function and increase efficiency.

6. Disposable, hygienic, convenient to carry, can be replaced frequently as needed to alleviate the discomfort of the wearer and always maintain a fresh feeling.

7. On cold days, it also plays a role of keeping warm.
