The foot-shaped part 2 having a middle laid sheet form is positioned on the sole of a user's foot, and the foot of the user is prevented from directly contacting the foot-shaped part of the slipper. In replacement, the holding part 3 is taken and demounted from the slipper body. Accordingly, the installation to the slipper body can be carried out in simple manner by the repulsive force for the bending of the wing-shaped part, without using an adhesive member or hooking member, and the slip during use can be prevented, and further, the direct contact of the instep part with the basic member of the slipper body can be prevented, and the sanitary and comfortable use can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a sheet-like material for slipper insoles that is used as an insole for slippers and can be freely replaced.

More specifically, we have created slippers that are always clean and hygienic, and free from the sticky and uncomfortable feeling caused by sweating and stuffiness during semi-humid conditions after taking a bath, hot and humid conditions such as during the rainy season and summer. The present invention relates to a sheet-like material for slipper insoles.

[Conventional technology] Conventionally, it has been used especially in hotels, inns, polling alleys, saunas, hospitals, schools, etc., as well as public facilities such as sleeper trains and airports.
The slippers provided in transportation facilities are inevitably extremely unsanitary, as a wide variety of people are constantly changing and using the same slippers semi-permanently, unless they are damaged or damaged. This may also lead to the transfer of athlete's foot. In addition, slippers stick to your feet especially when you get out of the bath, which makes you feel uncomfortable.Furthermore, if you wear slippers during Japan's hot and humid seasons such as the rainy season or summer, your feet will always feel damp or sticky. It was something. These sensations were particularly severe in PVC-based slippers, which are often used as slipper materials because of their low cost.

Furthermore, in recent years, so-called paper products, which are mainly made of polyethylene sheets and have been added with fibrous activated carbon deodorant,
Slippers are covered. These slippers are certainly light and not too bulky, making them convenient to carry around, but the bottom of the slippers is flat and too soft, making them uncomfortable to wear, and the cover sheet that covers the toes and the bottom sheet Since the sections were close together, there were problems such as difficulty in walking around.

Furthermore, as a replaceable slipper insole sheet, Japanese Utility Model Application No. 62-153905 discloses a slipper cover in which two pieces of nonwoven fabric consisting of a base part and a shell part are connected.
A slipper cover was proposed that was integrated with the slipper body using an adhesive member and a notch.
Japanese Patent No. 2605 proposes a slipper insole that integrates the slipper insole and the slipper body using a locking means such as an adhesive tape or a hook-and-loop fastener.

However, these conventionally known devices require the use of adhesives and hooks to attach them to the slipper body, which inevitably stains or damages the slipper body and makes it difficult to attach the slipper. It is very troublesome, and furthermore, when replacing the used insole with a new one, there are hygiene problems such as there is no place to hold it, and it is difficult to change it, so you have to grab the dirty part and replace it. However, it was not necessarily practical.

[Problems to be Solved by the Invention] In view of the above-mentioned points, an object of the present invention is to easily realize slippers that are always fresh, hygienic, and provide good comfort. The purpose is to provide a replaceable sheet-like material for slipper insoles. Furthermore, it is an object of the present invention to provide a sheet-like material for a slipper insole that can be attached to a slipper body without using any adhesive material.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the inventors of the present invention have made extensive studies and found that the slippers have a structure in which they can be easily replaced, and which can be easily replaced while being worn. A fresh and hygienic condition can always be obtained by providing a sheet-like material with a wing chamber shape that does not cause generation or misalignment with the base, and replacing the sheet-like material each time it is used. This discovery led to the present invention.

That is, the sheet-like product for slipper insoles of the present invention consists of a foot-shaped part, an airfoil-shaped part, and a handle part, and the adhesive member and/or the hook can be attached to the airfoil-shaped part without using the action of the members. This is a sheet-like article for a slipper insole, which is characterized in that it can be attached to a slipper body by a repulsive force against bending of the part.

A preferred embodiment of the sheet material for slipper insoles of the present invention is particularly characterized in that the sheet material is made of a nonwoven fabric having a basis weight of 30 to 500 g/d. Alternatively, the surface of the sheet-like article is particularly characterized by an uneven surface. Alternatively, in particular antibacterial and/or bactericidal agents and/or
Or, it is characterized by containing or having an antifungal agent attached thereto. Alternatively, a deodorant may be included or attached thereto. Alternatively, it is particularly characterized by the fact that it contains or is attached with a fragrance. Alternatively, the slipper insole sheet-like material is particularly characterized in that it is provided with an element that allows it to be determined whether it is before and/or after use.

Alternatively, the slipper insole sheet-like material is particularly characterized in that it is provided with an element that allows identification of the owner.

[Function] Hereinafter, the replaceable slipper insole sheet-like material of the present invention will be described in more detail with reference to the drawings and the like.

In the present invention, the shape of the sheet-like material for the slipper insole is larger than the shape of the foot surface as shown in FIGS. 1, 2, and 3. It has an airfoil-shaped part 1 and a handle part 3 on the foot-shaped part, and by constructing the airfoil-shaped part with a material having this shape and an appropriate modulus of rebound,
Even without using adhesives or hooks, it can be easily attached to the slipper body due to the repulsive force against bending of the airfoil-shaped part, preventing slippage during practical use, and furthermore, the top of the foot can be attached to the slipper body. This prevents direct contact with the base material, making it hygienic and comfortable to use.

FIG. 4 is a schematic diagram illustrating the state of the slipper insole sheet according to the present invention when it is attached to the slipper body. It is worn by being inserted into the instep of the foot (not shown).

Of course, the last part 2 of the slipper insole sheet according to the present invention is located on the sole of the wearer's foot, so that the wearer's foot does not directly touch the last part of the slipper. Also,
When replacing, all you have to do is pinch the handle 3 and remove it from the slipper body.

As the sheet material, non-woven fabric, paper, knitted fabric, etc. can be used as appropriate, but it is necessary to use something with a certain degree of tension and stiffness so that it can be attached to the slipper body due to its repulsive force against bending. , in terms of rebound modulus,
It is important to use 70% or more.

Note that here, the repulsion elasticity modulus is a value determined by the following method.

Measuring equipment: Compressive elasticity tester as mentioned above Sample size: A sample of width 3 cm x length 6 cm was folded in half in the length direction.Measurement method: Here, tl: Apply initial load (50 g/car) thickness (
mm), t2: Thickness (mm) when a load (300 g/cnf) is applied, t3: Thickness (mm) when returning to the initial load (50 g/Ci), as the sheet material,
Among these, nonwoven fabrics are preferably used because they are excellent in many aspects, such as cost, cuttability, prevention of tearing from cut parts, tactility, tension/firmness, shape retention, and strength.

However, it is needless to say that the sheet is not limited to non-woven fabric sheets, and paper, knitted fabric, etc. may be used as appropriate depending on the purpose, use, material of the slipper, etc.

The basis weight of the sheet-like material is preferably in the range of 30 to 500 g/rrf, and if it is outside this range, that is, if it is low in basis weight, it may lack tension and elasticity or tear easily.
It has poor integration with the slipper base material, and on the other hand, a high basis weight gives a heavy feeling, which is generally undesirable.

As the nonwoven fabric, those obtained by dry method, spunbond method, paper making method, etc. can be used, but they are not limited to these methods. Any method may be used as long as it has excellent tearing and tearing strength and does not cause problems such as fraying from the cut surface.

It is preferable that the surface of these sheet-like materials has appropriate unevenness. In other words, the unevenness of the surface is effective in preventing the slipper from slipping when worn,
Proper stimulation of the soles of the feet also prevents fatigue.

Furthermore, it is more preferable for the sheet-like material to be subjected to antibacterial, deodorizing, or aromatic processing, as this is hygienic and can soften the surrounding atmosphere.

Antibacterial agents, bactericidal agents, and/or fungicides include aldehyde compounds such as formaldehyde, glyoxal, and geltaraldehyde, ethanol,
Alcohol compounds such as isopropyl alcohol and benzyl alcohol, peroxides such as hydrogen peroxide, sodium percarbonate, and sodium peroxide pyrophosphate, free iodine preparations, iodine compounds such as organic iodine compounds, inorganic chlorine compounds,
Cationic surfactants such as organic chlorine compounds, alkylmethylbenzylammonium salts, alkylisoquinolium salts, amino acid type or imidazolinium betaine type amphoteric surfactants, cationic surfactants such as sodium lauryl sulfate, phenol, reseal , phenolic compounds such as cresol, 0-phenylphenol, and bisphenol, biguanide compounds such as chlorhexidine salts and polyalkylene biguaniline salts, benzoic acids such as benzoic acid, sodium benzoate, and isobutyl p-oxybenzoate, sorbic acid, Thiobendazole dehydroacetic acid, propionic acid compounds, tannin salicylic acid, water-soluble vinyl polymers, quaternary ammonium compounds, quaternary phosnium compounds, hydroxydiphenyl ether, sulfonate compounds, 2-methyl-isobutiazolin-3-one. A wide range of antibacterial and antifungal agents used in general industrial applications can be used, including food additives such as metal salts such as magnesium chloride, sulfur compounds, benzimidazole compounds, and nitrogen-containing organic cyclic compounds.

In addition to deodorizing agents such as activated carbon, titanium oxide, and ceramics, we also use natural plant-based, artificial oxidizing enzyme-based, and
Iron-ascorbic acid compounds, phthalocyanine derivatives, oxycarboxylic acid compounds, and the like can be used.

These antibacterial agents and deodorants may be used simply by being impregnated, coated, or attached to the sheet-like material of the present invention, or may be used by being appropriately included in microporous materials such as activated carbon or ceramics. The specific method for retaining and containing it in the sheet-like material of the present invention may be appropriately selected depending on the drug used.

Furthermore, there are various methods for imparting fragrance, but for example, α-pinene, β-pinene,
Coniferous oils such as cedrol, lavender ingredients such as linalool and linalyl acetate, and linemon found in oranges and lemons are kneaded into it, or these blended essential oils are made into capsules and embedded in fibers. be able to.

Furthermore, as a means of emphasizing hygiene, the distinction between before and/or after wearing is clearly made so that a third party can determine whether the sheet-like material for slipper insoles of the present invention has already been used or not. It is also preferable to keep the For example, a method in which a very small amount of colored material is made into a capsule and embedded in a sheet-like object, and when worn, the capsule ruptures and the sheet-like object is colored so that it can be identified, or In particular, it is possible to use a method such as using a sticker marked as used and covering it with a very weak cover object so that when worn, the cover object is torn and the marking becomes obvious. However, it is of course not limited to these methods. In short, any method may be used as long as it makes it clear before and after use.

Furthermore, we emphasize hygiene and the fact that it is personal property.
It is also preferable to provide a sense of security to the user. For example, a method such as printing letters of the alphabet, numbers, etc. can be used, but of course, the method is not particularly limited to these methods. In short,
Any method may be used as long as the owner can determine which slipper he/she was using.

The slipper insole sheet-like material of the present invention has a sheet-like material with excellent tension and stiffness as an airfoil-shaped part, so that the slipper body can be easily maintained during use without using special adhesive materials. In addition, by appropriately replacing the insole sheet material when wearing slippers, slippers can be easily and inexpensively made, hygienic, and comfortable to wear. This allows the use of slippers at all times.

[Example] Next, Examples will be shown, but this is for the purpose of clarifying the present invention, and the present invention is not limited to or restricted by such Examples.

Example 1 A nonwoven fabric made of polypropylene fibers and having a basis weight of 200 g/rrf was prepared in the form of a sheet by being thermally bonded with an embossing roll.

The nonwoven fabric was cut into the shape shown in FIG.

Next, the nonwoven fabric sheet was attached to one side of commercially available slippers made of vinyl chloride, and the other side was left as is.
I wore it barefoot all day and night.

As a result, the side to which the nonwoven fabric was not attached always had a slimy feel. This feeling was especially noticeable after taking a bath and was very unpleasant. Compared to this, the side to which the nonwoven fabric of the present invention was attached had a smooth and comfortable feel.

Furthermore, no phenomenon was observed in which the nonwoven fabric sheet came off from the slipper body while being worn.

Furthermore, when replacing the sheet the next day, it was extremely easy to remove, and since no adhesive was used, no phenomenon of staining the base of the slipper was observed.

Example 2 A heat-adhesive type nonwoven fabric made of polyamide fiber and having a basis weight of 150 g/rrf was prepared in the form of a sheet, and the nonwoven fabric was processed as shown in Table 1.

The sheets A, B, and C in Table 1 above were cut into the shape of a foot in the same manner as in Example 1, and when worn on slippers, a good feeling of wearing comfort was obtained.

C had excellent antibacterial properties, deodorizing properties, and aromatic properties that could never be obtained from the slipper body alone. [Effects of the Invention] The sheet material for slipper insoles of the present invention has the above-mentioned configuration. By doing so, the following excellent functions and effects can be achieved.

(1) Since no special adhesive is used, there is no need to worry about contaminating the base of the slipper.

(2) The slipper can be attached and detached from the slipper body very quickly and hygienically.

(3) Since the sheet-like product of the present invention is in a flat state before use, it is not particularly bulky, so it is convenient to carry when traveling.

(4) Since the insole sheet is simply replaced for the same slipper, the slippers are inexpensive and always provide the same comfort as new ones.

(5) When a nonwoven fabric is used for the sheet-like material, there is no need to prevent the cut surface from fraying, and the wing compartment sheet can be manufactured easily.

(6) You can always feel smooth and comfortable to wear even after taking a bath or during the summer.

■ It is extremely hygienic, and there is no need to worry about infecting other people's athlete's foot, for example.

The sheet material for slipper insoles obtained by the present invention has many features and effects as described above, and can be used in public buildings, homes, inns, hotels, saunas, and other facilities, and various transportation facilities. It can be effectively used for slippers, etc. that are always kept at home, and for personal use, if you always carry only the sheet material for slipper insoles of the present invention, you can use it wherever you go when traveling or going out. By attaching the sheet-like material of the present invention to the provided slippers and using the same, the above-mentioned effects can be easily obtained at any time.
