JPH0292302A - Disposable body warmer (kairo) holder for footwear like shoes - Google Patents

Abstract

PURPOSE:To provide an adequate heating effect with different heating capacity corresponding to each service condition by a method wherein a holder in which a disposable body warmer is enclosed is set on the toe side in a shoe and fits the widest part of the shoe so that the holder is prevented from moving or slipping aside during walking. CONSTITUTION:A base sheet 1 is adequately spread from the toe side 11 toward the heel side up to an end part 13 located within a range that it is beyond the widest part 12 but does not reach the ankle part, and a cover sheet 2 is attached over the base sheet with a joint 4. A pocket opening is furnished at the end part 13. Both the base sheet 1 and the cover sheet 2 are made of air-permeable material but are different in permeabilities. Therefore, air supply amount to a disposable body warmer 7 changes depending on which of the base sheet or cover sheet is set on the insole, so that calorific value can be changed. As the holder is set only on the front part of the insole, the holder can adapt itself to the deformation of the insole. In reverse use, a right foot holder can be used for left foot.

Description

[Detailed Description of the Invention] ``Object of the Invention'' The present invention relates to a disposable cloth holder, which is equipped with a disposable cloth inside footwear such as shoes, and has a heat-generating effect that varies depending on the usage conditions. It is an object of the present invention to provide a shoe holder that can be substantially effectively adapted to any type of shoes of different sizes suitable for providing a warming effect.

(Industrial field of application) A holder for installing and using a disposable cloth that uses a chemical exothermic reaction inside footwear such as shoes (prior technology) A disposable cloth that uses an oxidation reaction of iron powder, etc. is available today. It is widely used in Japan, and some proposals have been made regarding the application of this disposable cloth to footwear such as shoes.

For example, in Japanese Utility Model Application Publication No. 61-8013, an insole used in shoes is provided with a housing section for the above-mentioned disposable cloth, and a pyrogenic substance stored in a breathable bag is placed in the housing section. It is generally considered to be set.

Furthermore, in U.S. Pat. No. 4,249,319, it is announced that a housing section for disposable wool as described above is formed on the upper surface of slipper-like footwear to provide a warming effect to the toes of the wearer from the upper surface. .

(Problems to be Solved by the Invention) In the above-described conventional insole that forms a storage part on the insole itself to accommodate disposable clothing, this is quite a problem since the insole covers the entire sole of footwear such as shoes. , and it is inevitably expensive. In addition, footwear such as shoes come in various sizes because they are tailored to the size of the feet of each wearer, and insoles of various sizes are prepared to accommodate these different shoe sizes. This makes manufacturing complicated, making it difficult to manage the product during the storage and distribution process, and requiring unnecessary space, which also inevitably increases costs.

Although the product according to the above-mentioned US patent specification does not require such an insole and therefore does not have these disadvantages, in this case it is effective for the toes and the bottom of the foot because it provides a warming effect on the upper surface of the foot. Does not provide a warming effect. That is, I
Generally speaking, the warming effect has a strong tendency to propagate upward, and since there is a certain amount of space between the inner surface of the upper surface of the footwear and the surface of the foot, it is possible for the warm air to have a warming effect on the foot. There is a strong tendency for it to be lost without giving much. Furthermore, even if there is no need to manufacture a separate part from the footwear, such as an insole, the disposable lining storage area is always kept in the footwear, so when wearing the footwear in summer or warm seasons, , the housing section obstructs the loading/unloading operation.

Furthermore, in the case of the above-mentioned shoes, which accommodate the entire instep and even the heel, it is very difficult to put on and take off disposable socks, making it virtually impossible to use them. . Furthermore, the footwear having the above-mentioned color accommodating portion requires a lot of man-hours to manufacture and is inevitably expensive.

Furthermore, in footwear such as the shoes mentioned above, the warming effect required by the wearer varies considerably depending on the constitution or preference of each wearer, as well as the external temperature conditions. A warming effect that does not reach this level cannot provide a sense of satisfaction, even if we take great pains to use disposable gels.

Of course, it is possible to use disposable warmers with different degrees of heat generation, but this does not mean that manufacturers, sellers, and users of disposable warmers can use a variety of disposable warmers with different heat generating effects. It is necessary to prepare and manage the system, which is very complicated and has the disadvantage of being costly. In particular, if excessive or insufficient temperature is detected after the shoe has been placed in the shoe and used, it is recommended to discard the used one and replace it with a new one with a different heat generation effect. This is necessary, wasteful, and requires double costs.

"Structure of the Invention" Means 1 for solving the problem is a holder which is set on the inner bottom surface of footwear such as shoes and which receives and uses a disposable jacket, the holder being used from the tip of the foot to the end of the foot of the footwear. Similarly, a breathable covering material is attached to a breathable table piece that extends in the heel direction to form an end within a range that exceeds a wide range and does not reach the ankle, and the peripheral edge is joined, and the end of the table piece described above is attached. A shoe characterized in that a loading/unloading opening for the disposable footwear is formed in the part thereof, and the air permeability of the base piece and the wrapping material are made different so that the footwear can be turned upside down and inserted into the footwear. Disposable holder for footwear.

2. The base piece is formed by crossing or knitting a rigid fiber material such as vinylidene chloride, and polymerizing a synthetic resin network material with an uneven structure in the thickness direction, and making it a breathable nonwoven fabric, a knitted woven fabric, or a perforated fabric. Claim 1: The base piece, which is like a sheet, is stiffened to have good extensibility against the inner surface of the sole, and an air layer is formed and maintained in the portion by the uneven structure of the synthetic resin net material. Disposable bag holder for footwear such as shoes as described in section.

3. The disposable footwear according to claim 1 or 2, wherein the base piece and the wrapping material are fibrous tissue materials having different densities and different air permeability. Kairo holder.

4. The disposable footwear holder for footwear according to claim 1 or 2, wherein the base piece and the wrapping material have different thicknesses to have different air permeability.

5. The end portion of the table piece and the end portion of the synthetic resin net material are welded and integrated, and an opening for inserting and removing a disposable bag is formed between the synthetic resin net material and the wrapping material. Disposable bag holder for footwear such as shoes described in item 2.

6. Shoes according to any one of claims 1 to 5, in which the disposable jacket accommodates an oxidized heat generating material in a container made of a breathable fiber material such as a non-woven fabric. Disposable holder for footwear.

7. Any one of claims 1 to 5, in which the oxidizing exothermic material is housed in a container in which the disposable tube is made of a resin film or a closed fiber tissue material and is made perforated to provide air permeability. Disposable cloth holder for footwear such as shoes described in (function) A disposable cloth containing a heat-generating composition that generates heat by reacting with oxygen using iron powder, etc., is housed in a breathable container, and is inserted from the loading/unloading port into the stand. and the wrapping material.

As described above, when the holder of the present invention that accommodates disposable bags is placed in the toe side of a shoe-like object, which is deeper than the widest part, the holder's largest width will be at the largest width of the shoe. Engagement prevents the holder from moving or being removed by the piercing step.

That is, when the wearer walks while the holder is set in the inner part of the shoe, heat is applied to the tip of the foot by the disposable holder, thereby warming the foot.

As described above, the holder of the present invention, which is set only on the toe side within the shoe, can respond appropriately to changes in the dimensions of the shoe.

In other words, even large shoes can be properly locked at the widest part, and for shoes that are too loose, it can be connected to the circumferential side or the inner surface of the sole and bent to provide a stable connection to the inner surface of the sole. A set can be made.

By using a material with a certain degree of rigidity for the base piece, the expansion center within the shoe can be properly performed.

A holder with different air permeability between the base piece and the wrapping material is used, and a disposable cloth is housed inside footwear such as shoes. By reversing and resetting the disposable heater, the amount of air supplied to the disposable heater can be changed, thus changing its heat generating action and changing its warming effect.

By changing either or both of the denseness and thickness of the tissue, the air permeability of the base piece and the wrapping material described above can be changed as appropriate.

In addition, by interposing a synthetic resin net material with a concavo-convex structure with a certain degree of rigidity, the air permeability through the base piece or enveloping material is improved, especially on the surface in contact with the synthetic resin net material. The heat generating effect of the disposable pad is made uniform on a plane, and as mentioned above, the base piece, which has a different air permeability than the covering material, is in contact with the sole of the shoe, and it is directed toward the inside of the shoe (i.e., the sole of the foot). The air permeability changes when the air is cooled, changing the warming effect.

(Example) Specific embodiments of the present invention as described above are explained as shown in the attached drawings.
As shown in the figure, the end portion 1 extends moderately from the tip of the foot 11 toward the heel within a range that does not exceed the maximum width portion 12 of the foot and does not reach the ankle.
An enveloping material 2 is attached to a base piece l on which a number 3 is formed, the peripheral edge portion is joined 4, and a loading/unloading port 5 is formed on the end portion 13 side. The end portion 13 may generally be straight, but in some cases it may be bent to some degree, for example, it may be a cutting line recessed in an arc shape.

In the present invention, the above-mentioned table piece 1 and enveloping material 2 are both breathable and have different air permeability. In other words, by using fibers with different density or thickness, or both, such as nonwoven fabric and felt, the air permeability can be changed as appropriate.
The table piece 1 and the wrapping material 2 with different air permeability in this way are
Depending on which one is set toward the sole (inner surface of the shoe), the amount of air supplied to the disposable sole will change depending on which one is set toward the sole (inner surface of the shoe). , thus its calorific value can be changed. It is easy to experimentally form a temperature difference of about 5 to 10°C, but depending on the case, it is possible to vary the temperature over a wide range of 3 to 20°C.

As shown in Fig. 3.4, the base piece 1 is made of a thick fiber having a certain rigidity and a diameter of 0.1 to 0.5 nm, such as vinylidene chloride, as shown in Fig. 3.4. It is preferable to use a polymerized net material 6 formed by crossing or knitting materials and forming bent portions 6a as shown in FIG. 4, thereby creating a certain space between the inner surface of the sole and the sole. By ensuring this, breathability is improved and heat generation is uniformly generated over a plane, especially for disposable warmers. As mentioned above, the wrapping material 2 is made of a felt-like material or a non-woven fabric that has a pleasant feel, and is preferably made to give a soft feeling to the sole surface of the foot. This gives effective extensibility to the wrapping material 2 and the stand piece 1, thereby achieving a stable set. It goes without saying that an adhesive may be used for the joint 4 at the periphery of these sheet materials 1.2 and 6, but it is also possible to weld these materials 1.2 together with the material 6 of synthetic resin. As a result, as shown in FIG. 2, it is possible to firmly form a joint 4 in which the materials 1, 2, and 6 are melted and integrated.

As is well known, the disposable bag 7 is housed in a bag 70 made of breathable fabric or sheet, and is loaded and unloaded between the base piece 1 and the wrapping material 2 through the loading/unloading port 5. In the case of this embodiment in which the mesh member 6 having the bent portion 6a is also used on the stand piece 1 as described above, the bag 7 as described above is used.
The disposable shell 7 housed in the cough mesh material 6 engages with the uneven bent portion 6a of the cough mesh material 6, and does not move due to frictional sliding during walking, and the covering material 2 is also properly bonded. A stable containment condition can be obtained.

The amount of warm heat obtained from the disposable pad 7 in the holder of the present invention, which is located on the inside sole of footwear such as shoes, is distributed evenly around the foot as the foot moves during walking, and is distributed inside the shoe including the toes. Naturally, it is possible to provide a warming effect to the entire foot area.

In the present invention, the warming effect changes by inverting the holder as described above, but since such inverting operation is only set on the front half of the sole in the present invention, -
Even if the shoes are the same, they can quickly respond to changes in the shape of the sole surface.

However, it is well known that a pair of shoes are symmetrical in shape, so when reversing the shoes as described above, the one for the right foot should be replaced by the one for the left foot, and the one for the left foot should be replaced by the one for the left foot. By setting it for the right foot, you can use it without straining yourself at all.

As described above, the device according to the present invention can immediately respond to dimensional changes in footwear such as shoes, so there is no need to prepare holders for each size. Able to respond quickly to changes. Therefore, manufacturing and management become very easy, and it is clear that the product can be manufactured and provided at a very low cost, considering that only the toe part needs to be small as mentioned above.

``Effects of the Invention'' According to the present invention as explained above, a product can be obtained at an extremely low cost, and it is possible to stably apply the product to the inner surface of the sole, and not only can it be used with less discomfort, but also can be reversed. This invention has great industrial effects because the warming effect can be changed appropriately depending on the use, and it can be used in accordance with each usage condition.
