2. Description of the Related Art A sleeping bag, a futon, a winter clothes, and the like having feathers as a padding (in this specification, referred to as a futon) are widely used. Feather has a very delicate shape, so when used as a filling, it easily contains air, so it has high heat insulation, is very light compared to cotton cotton, has flexibility and elasticity, etc. It is prized as an expensive, luxurious and valuable item.

By the way, the feather as a raw material is literally a feather of a waterfowl or the like, which is usually imported in a bag or the like. Therefore, during the survival of waterfowl, etc., there is a high possibility that the bait fungus, mites, larvae, etc. were infested in the feathers, and it is highly possible that these pests and harmful bait fungi etc. are mixed in the raw feathers. It is a thing.

Of course, the manufacturer of raw material feathers usually removes the harmful insects and harmful fungi in the process of collecting feathers from waterfowl and removing small bones to produce raw material feathers. However, it cannot be expected that the pests mixed in the raw material feathers will be completely exterminated. Moreover, the pests mentioned above
It may be attached after the production of raw material feathers, and mold and other harmful bacillus may be attached at any time and anywhere.

If the above-mentioned harmful insects are mixed in the feather futon or the bait fungus adheres to the feather futon, mites, feathers, etc. may be used by the user while using the futon at home. Or the feathers are affected by the bacillus and the like, causing an offensive odor. Since the down futon and the like are expensive as described above, the futon and the like must be manufactured more completely after the bacillus fungus and the harmful insects are completely exterminated. Of course, if the feathers already have an offensive odor, they must be decomposed and removed.

[0006] Moreover, since the futon and the like are used by the user in contact with the body, the chemical activity is restored when the insecticide has a persistence, the insecticide having an offensive odor, or when it is wet with water at a later date. Since such insecticides and the like must not be used, the method for insect killing of feather futons is naturally limited.

As a method for insecticidal and sterilization of feather futons and the like suitable for the above purpose, as a result of intensive research by the inventor, as a result of exposing the raw material feathers to ozone in the washing room or the tank We have already announced the method of decomposing and cleaning the organic pollutants and odors attached to the feathers by the generated nascent oxygen, as well as exterminating the bacillus and pests that have also attached.

[0008] By the above method, it was found that the bait fungi and pests in the raw material feathers are almost ideally exterminated, the deodorizing effect is exerted, and the organic pollutants are decomposed and washed. However, mites, plums, etc. If the pests of the
Although it can be completely exterminated by the above method, it was also found that while these pests were in the egg state, they were not easily killed by exposure to ozone.

Therefore, as an effective control method for insect pests in the egg state, the insecticide, sterilization, and sterilization are carried out for a period from the spawning of the insect pests to hatching, that is, for about a week. It is desirable to continuously perform methods such as deodorization and mildew prevention, and the insecticidal purpose can be achieved by continuing the extermination method for at least 2-3 days.

However, exposing the raw material feathers to ozone in the cleaning chamber or the tank for a long period of time as described above requires a large number of facilities such as cleaning chambers.
Since it will occupy a large area in the factory,
It is very uneconomical and impractical from a financial standpoint and from the standpoint of efficient use of equipment.

[0011]

The problem to be solved is to eliminate the harmful insects and bacillus contained in the raw material feathers from the feathers by ozone in the washing room as previously announced by the inventor. The method of exposing has a temporary effect,
It is also effective for controlling bacillus and deodorizing, but in order to completely control pests, this method must be carried out for a long period from the spawning of the pest to the hatching, which is economical. The point is that it is virtually impossible.

[0012]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is characterized in that after the ozone is blown through a partial opening of the skin, such as a futon packed with feathers, the opening is opened. Based on the method of enclosing ozone inside the futon by closing the part, as another similar means, in the step of packing feathers into the futon skin or the like by wind pressure through the duct, A method in which an ozone supply pipe is opened at an appropriate place of the duct, ozone is blown into the inside of a skin of a futon or the like from the ozone supply pipe to seal it, and further, a completed feather futon or the like is put in a vacuum tank. By depressurizing the inside of the tank and blowing ozone into the vacuum tank,
A method of enclosing ozone inside the completed futon,
And a futon etc. in which ozone is enclosed by each of the above means,
By wrapping it in a packaging material made of highly airtight material such as vinyl sheet and sealing it, the concentration of ozone inside the futon etc. was maintained for a relatively long period of time. A method such as mold.

According to this method, since ozone is enclosed inside the completed futon, the completed futon is stored in a warehouse, wholesaled to a wholesaler etc. according to the order, and the wholesaler etc. sells it. Ozone is sealed inside the futon or the like for at least a few days within a long period before being transported to the store for display and reaching the user's hand.

Therefore, even if the pest attached to the raw material feathers is a futon etc. produced immediately after spawning, the pest eggs have almost completed hatching within the above-mentioned period, and as a result, they have just hatched. The harmful insects are also exposed to ozone, and the harmful insects are completely exterminated.

[0015]

The present invention will be described in detail below with reference to the production of a feather futon shown in the drawings. Needless to say, the present invention is not limited to the feather futon, and can be similarly applied to other cold protection equipment including feathers as a padding.

[First Embodiment] FIG. 1 is a layout view showing a first embodiment of the present invention. As shown in FIG.
Reference numeral 1 denotes a structure in which a feather 2 is wrapped in a futon skin 3. An opening 4 is provided in a part of the futon skin 3 by leaving unsewn parts, and ozone generated from an ozone generator 5 is stored in an ozone storage tank 6 After being stored in, the pump 7 feeds it into the inside of the futon skin 3 through the pipe 8. The feathers 2 are packed in the futon skin 3, and the space other than the feathers is filled with air. However, by sending ozone from the pipe 8 by the above-described method, the air inside the futon skin 3 is blown. The air leaks to the outside through the texture of the futon skin, and instead the air containing ozone fills the futon skin 3, so that ozone is enclosed in the futon skin 3. However, it is desirable that the feathers be previously dried with hot air.

In the above description, the ozone generator means, for example, a device for applying a high voltage to both electrodes of a double glass tube to supply oxygen or dry air to generate silent discharge between the electrodes to generate ozone. A commercially available ozone generator may be used, and the generated ozone may be directly sent to the inside of the futon skin 3, but if necessary, the ozone storage tank 6 may be used.
It is also possible to have a structure in which it is temporarily stored in and then sequentially supplied to the inside of the futon skin 3.

On the other hand, a sensor 9 for detecting the ozone concentration is inserted inside the futon skin 3, and the ozone concentration in the futon skin 3 is detected by the signal from the sensor 9. When the concentration becomes higher than a certain level, the supply of ozone is stopped, and the opening of the futon skin 3 is closed so that ozone is enclosed in the futon skin 3.

Next, the degree of ozone concentration in the futon skin will be described. The present invention, for the above-mentioned purpose, for the period from the egg egg of the pest is laid in the futon skin until hatching, ozone of a concentration or more effective for exterminating the adult insect of the pest is enclosed. Is ideal,
Usually, it can be said that it is sufficient to maintain an effective concentration for about 2-3 days at most. This is because adult pests remain in the feathers that have been packaged and imported by imports, etc., and it is rare that they will lay eggs just before insecticide in the futon manufacturing process. Most of the substances mixed in are those that have been spawned long before and hatching has been delayed, so treatment such as exposure to ozone to exterminate adult insects of the pest, exposure to hot air, etc. It is considered that the eggs are almost hatched within 2 to 3 days after the treatment, and those not hatched within the period are killed as they are due to the stimulation by the treatment.

Adults such as mites and larvae seem to be sufficiently killed in an ozone environment of about 5 ppm or more. It is desirable that at least 5 ppm or more of ozone remains in the futon skin during the period from the spawning of the mites and the fluffs to the hatching of the mites, etc. However, it can be said that the effects of the present invention can be expected if the ozone is enclosed for about 2 to 3 days.

By the way, the ozone enclosed in the futon skin as described above gradually disappears by being naturally decomposed and gradually released to the outside through the texture of the futon skin. However, feather futons require that fine feathers do not leak from the weave, and because they are expensive and luxurious products, the fact that they use high-quality cloth with tight futon skin also contributes. Therefore, there are not many things that leak out from the texture in the environment of normal storage and transportation, and according to the results of the experiment, if about 20 ppm of ozone is enclosed in the futon skin, it will be possible even after 2 to 3 days. It seems that the ozone concentration of 5 ppm or more can be maintained for the time being. Therefore, it is desirable that the concentration of ozone to be enclosed at the beginning of manufacturing the futon is about 20 ppm or more.

By the way, although ozone is a gas useful to the human body, it is said that absorption of a high concentration of ozone will damage the respiratory organs of the human body. However, the person who stores and transports the feather quilts may be damaged by breathing ozone leaking from the quilts, unless ozone is added to the quilts. Since it rarely leaks to the outside after passing through the weaves, it is limited to the case where the concentration of ozone in the futon skin is very high.
It is considered to be sufficiently safe up to about pm.

Therefore, in order to maintain an effective concentration of ozone inside the futon skin, the concentration of ozone initially enclosed should be about 20 ppm or more, and if it is 2000 ppm or less, It can be said that the concentration is not dangerous for carrying out the invention. However, when the method of the third embodiment described later is also performed, the initial ozone concentration may be lower. This will be described in the description of the third embodiment.

Since the permissible range of the ozone concentration in the futon skin is very large as described above, the ozone concentration in the futon skin is measured one by one by the sensor as in the above embodiment. Instead of blowing in, refer to the amount of ozone to be blown in, the time, etc., or, based on the experience and intuition of the worker, such as the odor of ozone leaking from the futon skin, stop supplying ozone when it is 20 ppm or more, The opening 4 of the futon skin 3 may be closed.

Of course, the worker who supplies ozone to the inside of the futon according to the method of the present invention should take measures to prevent a large amount of ozone from being drawn in by using a mask provided with a reducing agent. You will need to collect it. Also,
The ozone leaked to the outside through the texture of the futon by the operation of injecting ozone into the futon can be recovered and returned to the ozone generator, or contacted with a reducing agent. May be released into the atmosphere.

[Second Embodiment] FIG. 2 is a conceptual diagram showing a process of a second embodiment of the present invention. This is from a feather supply device 10 such as a feather storage tank or a hopper to ducts 11 and 1.
This is a method of blowing ozone together with the feathers and air in the step of blowing feathers into the inside of the futon 3 through the opening 4 of the futon 3 through 1'by wind pressure.

That is, in the apparatus configured such that the feathers supplied from the feather supply device 10 are fed through the duct 11 into the futon skin 3 by the wind pressure of the fan 12, between the ducts 11 and 11 '. A mixing valve 13 is interposed between the two, and when the mixing valve 13 is operated, ozone generated by a separately provided ozone generator 5 passes through the ozone supply pipe 8 and opens into the ducts 11 and 11 '. There is. As a result, the air containing feathers in the duct 8 and ozone are mixed, so that the tip of the duct 11 'is inserted into the opening 4 provided in a part of the futon skin 3 to blow the feathers and the like, and the futon is blown. Feathers and air containing ozone are blown into the skin 3. Also in the case of this embodiment, if the feathers are exposed to hot air by a method such as mounting a heater in the fan 12,
It is desirable because it helps dry and kill insects.

Of the feathers, air, and ozone, since air and ozone are gases, part of them leaks out through the texture of the futon skin, and the rest of the air and ozone are
Since it remains in the futon skin 3 together with the feathers, air containing ozone is enclosed in the futon skin 3 by sewing and closing the opening portion 4 here. The concentration of ozone sealed inside the futon skin can be adjusted by adjusting the mixing valve 13, and with or without a sensor by the same method as described in the first embodiment. It is desirable to adjust the ozone concentration to 20 ppm or more and 2000 ppm or less while detecting the ozone concentration inside the futon skin or without using such a detection device as described above.

In the above description, the feather supplying device is a device containing feathers, a bag containing feathers, a hopper, or the like, and is a device for supplying a small amount of feathers by the suction force of the duct, and the fan 12 is It is for generating the wind pressure for conveying the feathers in the ducts 11 and 11 '.

[Third Embodiment] FIG. 3 is a conceptual diagram showing a third embodiment of the present invention. As shown in the figure, the vacuum tank 1
Put the finished down futon in 4 and then vacuum pump 15
After the inside of the vacuum tank 14 is evacuated by the ozone generator 5 or the ozone storage tank 6 connected thereto,
The pump 7 supplies ozone into the vacuum tank 14.

In the above process, when the vacuum tank is evacuated, the air inside the feather futon also becomes a vacuum. Therefore, if the switching valve 16 is operated next to supply ozone into the vacuum tank 14, the ozone is supplied. Since the inside of the feather futon 1 is filled through the texture of the futon skin, the first embodiment, the second
Ozone can be enclosed inside the futon skin at a concentration similar to that described in the examples. Of course, the term "vacuum" as used in this specification does not mean a perfect vacuum but a state in which there is very little air, as is commonly used in society.

If ozone is enclosed in the inside of the futon 1 completed by the third embodiment, it is not necessary to close the opening of the futon skin after the ozone is enclosed, as in the first and second embodiments. Will be able to ship. The finished futon means a state in which feathers are packed in the futon skin, and it goes without saying that there is no problem even if there is a step of attaching a cover or a collar after that.

FIG. 4 is a conceptual diagram showing a fourth embodiment of the present invention. In this method, as shown in the same figure, a wrapping material made of an airtight material such as a vinyl sheet is obtained by filling ozone into the futon 1 according to the first to third embodiments. In this embodiment, it is sealed in a bag 17 made of a vinyl sheet and sealed by a fastener 18.

[0034] When making this embodiment, the ozone in the futon 1, since there is no leak out into the atmosphere from the interior of the comforter by packaging material, the concentration of the pre futon 1 as the respective embodiments It is not necessary to set it so high, and it is ideal if the concentration is such that ozone is naturally decomposed and disappears within about one week. However, as described above, 2
Approximately 3 days, if ozone remains, the effect will be fully demonstrated. According to the experiment, if the initial concentration is set to about 10 ppm, the concentration of ozone in the futon skin will be about 5 ppm after 2 to 3 days. Seems to be kept above.

In carrying out this method, it is more effective to blow ozone into the bag in which the completed futon is put and to seal the bag, but this will prevent the bag from expanding and becoming bulky. For this purpose, it is effective to suck air from the inlet of the bag in advance to reduce the pressure and then blow ozone into the bag to seal it. Through all the above examples, instead of putting the raw material feathers into the futon skin as it is, the raw material feathers are once exposed to ozone or ethylene oxide, or insecticidal or sterilized by ultraviolet irradiation,
It goes without saying that the present invention may be carried out for those that have been treated for deodorization, mildew prevention and the like. Even in that case,
The present invention produces an effect against pests and the like that survive in the egg state when the above treatment is performed. Also,
The description has been given by taking the feather futon as an example, but the present invention is not limited to this, and can be applied to all things with feathers as a padding, such as winter clothes, feather pillows, and sleeping bags.

[0036]

Industrial Applicability As described above, the present invention blows ozone from a partial opening of a leather, such as a futon packed with feathers, and then closes the opening to enclose the ozone to remove the futon. It keeps ozone inside,
As a result, the feather quilts will be stored inside the quilts for at least a few days during the long period from storage to delivery to wholesalers, arranging at retail stores, and reaching the user's hand. Since ozone can be left behind, even if the mite, the plum fly, etc. are in a state immediately after spawning, they will be exposed to an environment containing an effective concentration of ozone during the period, It is completely exterminated.

Further, in the step of packing the feathers into the inside of the futon or the like by the wind pressure through the duct, an ozone supply pipe is opened at an appropriate position of the duct, and ozone is fed together with the feathers into the futon or the like from the ozone supply pipe. In the method of blowing and enclosing the inside of the leather, the work of filling the inside of the futon skin with the ozone is performed at the same time as the work of filling the feathers with the feathers, so that it is not necessary to separately perform the work for enclosing the ozone.

[0038] A method of enclosing ozone into the completed futon by putting the completed down futon into a vacuum tank, depressurizing the inside of the tank, and then blowing ozone into the vacuum tank is described in advance. Since it is not necessary to sew with leaving the opening in the sewing machine or to close the opening after injecting ozone, the futon sewing process does not become complicated, and excess ozone is released to the outside. The act of managing the can be easily performed.

If a sensor is placed inside the futon skin and the concentration of the inside of the futon skin is detected and controlled by the signal from the sensor, the ozone concentration in the futon skin is required and sufficient. It can be easily enclosed in various ranges.

Furthermore, according to each of the above-mentioned methods, the futon containing ozone is wrapped in a packaging material made of a highly airtight material such as a vinyl sheet and hermetically sealed so that the concentration of ozone inside the futon can be reduced. It can be maintained for a longer period of time, the insecticidal effect is more complete, and the danger that ozone will be harmful to the person handling this package during transportation can be avoided.

As described above, the methods of insecticidal, sterilizing, deodorizing, and antifungal, etc. of the feather futon of the present invention are
Not only effective for sterilization, deodorization and mildew prevention, but also for eggs of pests that may be mixed in the feather futon,
It can be disinfected after it hatches.
