Description

Bedclothes having good water-proof and dust-proof characteristics

The present invention relates to a bedding with a new function, and more particularly to a bedding with a function such as water repellency, antifouling and antibacterial.

In general, bedding is a product that is widely used as one of the most basic daily necessities in Korea, which is used to the ondol culture. These beddings are widely used in general homes, duvet blanket pillows, etc. can be said to be a typical example. These beddings are used and functions different from each other according to each product, so that each will be manufactured in a specific form in consideration of its characteristics.

FIG. 1 is a diagram showing a pillow 10 that has been widely used as a bedding material since ancient times. The pillow 10 is to support the user's head while lying down and relax, so that the user can rest comfortably, inevitably wraps the body portion 12 and the body portion 12 made of a soft and flexible material It consists of the inner fabric 14 which maintains the form, and the outer fabric 16 which gives the beautiful aesthetic which surrounds the exterior of the inner fabric 14. This basic configuration is no exception in the case of blankets, cushions, blankets, etc., although the form is different, the function and basic concepts are the same.

When the user actually uses such bedding, the outer fabric 16 is exposed to the outside, and is easily contaminated or soiled from the surrounding environment. The contaminants are washed and used again. Therefore, the outer fabric 16 is mainly using a synthetic fiber-based fabric, even in this case seems to be no problem. On the contrary, the fabric for fabric 14 is mainly made of cotton fabric, which is a natural fiber, which is softer in touch and better in breathability and better in sweat absorption than chemical fiber. This is because it does not cause allergies to the human body.

However, the use of such natural cotton fabrics for bedding has the following drawbacks: it is difficult to deal with such contaminated areas when they are soiled by prolonged use in these beddings or when the user inadvertently contaminates them. Used to occur. For example, when a user accidentally spills coffee or a drink, or when the user exhausts excessive sweats to wet bedding, or when a newborn child is breast-feeding or milk-feeding, or when children are children Natural cotton fabrics are almost impossible to remove contaminants generated in these situations, such as when playing with them and shedding them, or when the children are drenching the bedding by the urination phenomena that often occur during sleep. This was there.

Since the conventional fabric for fabric 14 is sewn with the cotton filled therein, it is often contaminated with the cotton filled therein, and these contaminants are often cotton or soft filler It was forced to dry with. This drying process had to be carried out in a state where the cotton or the filling material was soaked with moisture, it was difficult to dry properly, it was almost impossible to remove the traces left on the cotton fabric even after drying. As such, in the conventional bedding, it was simply dried without completely removing the contaminants from the fabric for fabric 14, and thus showed a ugly appearance in appearance, and also provided a cause of an unpleasant odor. It was. In addition, in the conventional bedding, there was always a concern that the contaminants that remained in the fabric for fabric 14 would cause decay or an unpleasant odor again if they contained proper moisture again. This phenomenon was more severe when the fabric for fabric 14 is cotton fabric as natural fibers rather than chemical fibers.

On the other hand, it has been found that there are several prior arts for the bedding and persimmon fabrics related to the present invention.

In Republic of Korea Utility Model No. 20-013697 "Pillow for easy replacement of pillowcases", the body portion 12 and the fabric for fabric 14 is formed integrally, the fabric for the outer fabric 16 is separated After forming, the outer fabric 16 shows a structure that can be easily coupled to the fabric for fabric 14, such as fastening rings and fastening straps. However, there is no specific reference to the fabric for fabric (14).

In addition, the Republic of Korea Application Publication No. 1991-3113 "pillow" relates to the pillow bundles to be filled in the body portion 12, the fine synthetic fibers in the form of a bundle, wrap it with a flexible foreskin and then cut it to a predetermined length It introduces one thing. However, this too is not introduced at all with respect to the fabric for the fabric 14 according to the present invention.

On the other hand, the prior art which is considered to be directly or indirectly related to the fabric for fabric 14 of the present invention is as follows.

Republic of Korea Patent No. 10-331722 "multifunctional fabric" relates to a composite fabric in which the knitted fabric and the adhesive bonded to each other. This is a coating treatment of the polyurethane composition on the fabric, the polyurethane composition contains a fragrance and a sunscreen, this composite fabric is described as excellent in touch and mechanical properties. However, according to the above patent specification, it can be seen that the above-mentioned fabrics are related to synthetic fiber fabrics because they are made of polyester yarn (see Example 1), and not to natural fiber fabrics, and can be used for bedding. It is considered a technology that has nothing to do with cotton fabrics present.

In addition, the Republic of Korea Patent Publication No. 2002-60876 "dry non-porous moisture-proof fabric" is to form an adhesive layer of a hydrophilic two-component polyurethane resin on a hydrophobic synthetic fiber fabric, a one-component polyurethane water on the adhesive layer Forming strata. However, the waterproof fabric is also related to synthetic fibers, and also improves durability and moisture permeability, it can be seen that it is not intended for cotton fabrics.

In addition, Republic of Korea Patent Publication No. 2002-60877 "Water-permeable waterproof fabric having moisture-absorbing quick-drying" is "hydrophobic synthetic fiber fabric + hydrophilic two-component polyurethane adhesive + one-component polyurethane resin layer + hydrophilic two-component polyurethane adhesive + sweat-absorbent quick-drying knitted fabric Introduces a composite fabric composed of However, this is also aimed at synthetic fibers, it can be seen that the technology related to the cotton fabric of the present invention.

As described above, according to the related art, a number of attempts have been made to improve the functionality of synthetic fibers. However, little or no technology has been developed for improving the functionality of cotton fabrics used in bedding.

The inventors of the present invention is a cotton fabric, the main ingredient of the fabric tissue is composed of cellulose, the cellulose component on the one hand provides a soft touch to the body and at the same time useful to prevent skin sensitivity On the other hand, it has hydrophilicity that attracts moisture and is easily contaminated by moisture-containing contaminants, and also has a negative aspect that provides conditions for the growth of decayed bacteria. Recognizing the fact that it is not possible to achieve the properties such as water-repellent oil-repellent antifouling properties provided in synthetic fibers by conventional water repellent treatment by the component, and began to develop the present invention.

The present inventors can obtain a water-repellent oil-repellent antifouling and antibacterial properties that can not be achieved at all in conventional cotton fabrics by adding a treatment process that can overcome the negative side of such cellulose, the cotton fabric having such a new function When used as a fabric for the fabric of bedding, it was confirmed on the basis of the objective data that a variety of new types of bedding can not be provided in the conventional bedding, and completed the present invention.

Therefore, an object of the present invention is to provide beddings having good water and oil repellency and antifouling properties and retaining antibacterial properties.

The present invention is a body part made of a soft and flexible material to achieve the above object, a fabric for wrapping the body portion and maintaining the shape, and the outer fabric giving a beautiful aesthetic to wrap the outside of the fabric for fabric In the bedding composed of a textile, the fabric for fabric is natural cotton fabric of its original material; A one-component polyurethane resin on one or both sides of the cotton fabric: a cellulose-modified urethane resin: a solvent-containing ratio of 50 to 60% by weight: 20 to 30% by weight: 10 to 30% by weight of a hydrophilic polyurethane adhesive layer; A film layer of a perfluorinated polymer formed on the adhesive layer; It provides a bedding, characterized in that it comprises a.

The subject innovation is characterized in that the fabric for the fabric of the above-mentioned fabrics using a fabric material made of natural fibers, by processing them.

Hereinafter, the beddings according to the present invention will be described in more detail with reference to the accompanying drawings. However, the accompanying drawings are provided only to be easily carried out by those skilled in the art, it is obvious that the present invention is not limited to the accompanying drawings.

2 conceptually illustrates the bedding 100 according to the present invention. The bedding 100 according to the present invention is a body portion 110 made of a soft and flexible material, the inner fabric to wrap and maintain the body portion 120, and wraps the outer fabric of the inner fabric It is composed of a fabric for outer fabric 130 to give a beautiful aesthetic. At this time, the body portion 110 is mainly for providing warmth and made of various cotton, chemical fiber yarn or feathers of various birds, etc., the outer fabric 130 is to form the outer covering of beddings Mainly, fabrics made of chemical fiber yarns are used, and predetermined patterns or various characters are printed on the outer shells.

The present invention is characterized in that it uses the fabric of the natural fiber that imparted water repellency and oil repellency and antifouling property to the fabric for fabric 120.

The bedding 100 according to the present invention uses a fabric 122 made of natural fibers manufactured by processing a natural material, unlike chemical fibers, as a fabric for fabric 120. Examples of the fabric 122 made of natural fibers include conventional cotton fabrics, woolen fabrics, and silk fabrics. Among them, it is more preferable to use cotton fabrics having good ventilation, soft touch, and well absorbing sweat and moisture. This is because it can meet the basic requirements of bedding which is widely used today. Therefore, in the present invention, synthetic fibers such as polyester fibers produced by an artificial synthetic process are excluded from the scope of the right.

In the present invention, the bedding fabric for fastening 120 includes a hydrophilic polyurethane adhesive layer 124 on one surface of the natural fiber fabric 122. The hydrophilic polyurethane adhesive layer 124 may be manufactured by a primary pretreatment process. The present invention is characterized in that the pretreatment step, the hydrophilic polyurethane component used in the pretreatment step is a one-component polyurethane resin: cellulose-modified urethane resin: solvent ratio of 50 to 60% by weight: 20 to 30% by weight %: It is preferable that it consists of 10-30 weight%. In the present invention, the hydrophilic polyurethane adhesive layer 124, the hydrophilic component thereof forms a primary reaction with the cellulose component constituting the main component of the cotton fabric 122, while the polyurethane component thereof is secondary It is adopted to form a reaction with the perfluorinated polymer 126 to be processed in the next process. In other words, the natural cotton fabric 122 is a cellulose-based component, and by the usual water repellent treatment, the cellulose component and the perfluorinated polymer form a weak bonding relationship with each other, and thus the water repellency required for the cotton fabric. Since the performance of oil repellent antifouling property and the like cannot be sufficiently achieved, the above pretreatment step is necessary to overcome such deficiencies.

In the present invention, the one-component polyurethane resin can be used that is usually used when processing a synthetic fiber fabric, it is preferable to use a cellulose-modified acrylate resin as the modified urethane resin. This is because the natural cotton fabric 122 contains cellulose as a main component, so that it is possible to more smoothly react with each other. In addition, the said solvent can use the product normally used.

In the present invention, the pretreatment process may be carried out in a manner conventionally performed in the field of textile processing, except for using each component as described above. In the present invention, when each component is used below the threshold, there is no significant difference in terms of the effect of the cotton fabric directly treated with a water repellent, and when used above the threshold, there is no significant difference in water repellency and oil repellency. Therefore, it is not preferable. On the other hand, the pretreatment process may be carried out by applying a thin hydrophilic polyurethane component having the above components and the composition ratio to the surface of the cotton fabric by a comb knife coating method, and then drying. Through this process, the adhesive layer 124 formed by the hydrophilic polyurethane component is formed.

The fabric for fastening 120 of the bedding 100 according to the present invention forms the adhesive layer 124 by the hydrophilic polyurethane component, and then forms a film layer 126 by the perfluorinated polymer thereon. In the present invention, since the Teflon-based water repellent was found to be the most suitable as the perfluorinated polymer, it is preferable to form a film layer using the same. The Teflon-based water repellent is a commercially available product that is developed by DuPont in the United States, and can be used by mixing other water repellents. In the present invention, the film layer 126 by the perfluorinated polymer may be completed by curing the cotton fabric after the pretreatment process with the Teflon-based water repellent, and then proceed in a manner that is performed in the field of fabrics Can be.

In addition, the fabric for the fabric 120 of the bedding 100 according to the present invention can form a film layer 126 of the water-soluble polyurethane adhesive layer 124 and the perfluorinated polymer on both sides at the same time. In this case, the method of immersing the fabric in the aqueous solution is more preferable than the application method by the comb knife in the manufacturing process.

Since the fabric for the fabric of the bedding material 100 according to the present invention has one or both surfaces thereof forming a film layer of the perfluorinated polymer, even if the user or children spill water, milk or coffee on it Also in the case of building, the water repellency and oil repellency are very excellent.

As such, the textile fabric for bedding according to the present invention has the most suitable performance for beddings using natural fabrics today. Accordingly, the bedding 100 in the present invention means a blanket, yo, cushion, bed pads, cushions, or pillows that are widely used today, the fabric for the above-mentioned fabric in the bedding 100 It is preferred to be used.

Hereinafter, the manufacturing method and the performance of the fabric for fabric fabric 120 used in bedding 100 of the present invention will be described in more detail through specific examples.

<< Example 1 >>

A fabric having a blend ratio of 100% cotton according to Korean Industrial Standards (KS K 0210-1998) was prepared and stored in a state free from contamination. On the other hand, a hydrophilic polyurethane resin composed of 60% by weight of a one-component polyurethane resin having a solid content of about 30%, 27% by weight of cellulose-modified urethane acrylate, and 13% by weight of a solvent (methyl ethyl ketone: toluene = 4: 1). Was applied thinly by a comb knife method, and dried through a drying chamber at about 55 ° C. Thereafter, 0.3 wt% of a Teflon-based water repellent developed by Dupont Inc. was used to make a water repellent aqueous solution. The pre-treated cotton fabric was completely immersed in the water repellent aqueous solution, which was taken out, and dried at 65 ° C. Thereafter, various tests were performed on the finished fabric.

<< Example 2 >>

In Example 1, 55 wt% of the one-component polyurethane resin having a solid content of about 30%, 30 wt% of the cellulose-modified urethane acrylate, and 15 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were performed on the finished fabric.

<< Example 3 >>

In Example 1, 55 wt% of the one-component polyurethane resin having a solid content of about 30%, 25 wt% of the cellulose-modified urethane acrylate, and 20 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were conducted on the finished fabric.

<< Example 4 >>

In Example 1, 50 wt% of the one-component polyurethane resin having a solid content of about 25%, 25 wt% of the cellulose-modified urethane acrylate, and 25 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were performed on the finished fabric.

<< Example 5 >>

In Example 1, 50 wt% of the one-component polyurethane resin having a solid content of about 25%, 20 wt% of the cellulose-modified urethane acrylate, and 30 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were performed on the finished fabric.

`` Comparative Example 1 ''

In Example 1, 45 wt% of the one-component polyurethane resin having a solid content of about 30%, 20 wt% of the cellulose-modified urethane acrylate, and 35 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were performed on the finished fabric.

`` Comparative Example 2 ''

In Example 1, 65 wt% of the one-component polyurethane resin having a solid content of about 30%, 25 wt% of the cellulose-modified urethane acrylate, and 10 wt% of the solvent (methyl ethyl ketone: toluene = 4: 1) Except for producing and using the constructed hydrophilic polyurethane resin, the remaining conditions were the same as in Example 1. Thereafter, various tests were performed on the finished fabric.

In order to examine the characteristics of the fabric for the fabric of the bedding 100 according to the present invention was tested through various methods as follows.

《Water repellent performance test》

For each of the cotton fabrics prepared in Examples 1 to 5 and Comparative Examples 1 and 2 described above, a test concerning water repellency was performed.

This is how much water absorbs such moisture when the fabric is exposed to water, and is usually determined by the American AATCC method.

Water repellency Measurement class Measure 100 Almost no moisture on the surface 90 Slight wetting on the surface 80 Show partial wetting and swelling on the surface 70 Surface shows swelling 50 Swelling over the entire surface 0 Swelling not only on the front surface but also on the back

According to the AATCC method (Inspection Method No. 22 spray method), the measurement grade was as follows.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 100 100 100 100 100 80 80

Therefore, it was found that the cotton fabrics according to Examples 1 to 5 had very good water repellency.

Oil repellency test

This is how much the oil component absorbs when the fabric is exposed to oil or the like and is usually measured by the American AATCC method.

In the oil repellency test, the measurement grade uses the most penetrating n-heptane from the least penetrating newsol to the more penetrating solvent, and measures the surface tension of the solvent dropped on the test fabric in that state. The grade is determined by the following criteria.

Oil repellent Measurement class Surface Tension (Dyne / cm 3) Standard test solvent One 31.5 New sol 2 29.5 New sol: n-hexadecane = 66: 35 (wt%) 3 27.3 n-hexadecane 4 23.5 n-decane 5 19.8 n-heptane

According to the AATCC method (Inspection Method No. 118), the measurement results were as follows.

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 4 4 4 4 4 3 3

Therefore, in the case of Examples 1 to 5 above it can be seen that it has a very high oil repellency, in the case of Comparative Example 1 and Comparative Example 2 it can be seen that it has a relatively low oil repellency.

<< water and water repellency test for each fabric after washing >>

After washing 20 times of the respective fabrics, the water repellency and oil repellency for each fabric was measured again, the measurement method was the same as the above case.

(One). Water repellency test results after washing:

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 90 90 90 90 90 70 70

(2). After washing, oil repellency test results:

Example 1 Example 2 Example 3 Example 4 Example 5 Comparative Example 1 Comparative Example 2 4 4 4 4 4 2 2

This is because the cotton fabric used for the bedding 100 of the present invention has very good water and oil repellency even after several washings, while the cotton fabric outside the scope of the present invention has its first characteristics when washed several times. It was accepted as a loss.

Antimicrobial Test

This causes an unpleasant odor when the cotton fabric used for bedding contains moisture, and recently, the controversy of the pathogen infection caused by bedding is controversial. Given the need for testing. Since such a test requires very professional and objective test results, the test fabric of the cotton fabric fabric and the untreated cotton fabric fabric according to Example 1 was commissioned by the Korea Yarn Textile Testing Institute to carry out an antimicrobial test. (Reception number: 41-41-03-24344)

Figure 3 is a photographic data showing the test results carried out by the Korea Yarn Textile Testing Institute, Figure 3a is a photographic data about strain 1, Figure 3b is a photographic data about strain 2. (At this time, since Comparative Example 1 is outside the scope of the present invention, it is clear that it was excluded from the antimicrobial test.)

Specific conditions regarding this antimicrobial test were as follows.

Weight of sample 0.4g Increase Strain 1: 48 times Strain 2: 47 times Used strain Strain 1: Staphylococus aureus ATCC 6538 Strain 2: Klebsiella pneumonniae ATCC 4352 Inoculation bacteria concentration Strain 1: (1.4 ± 0.3) x 10 ⁵ / ml Strain 2: (1.6 ± 0.3) × 10 ⁵ / ml Type of culture medium TWEEN 80 (0.05%)

Under these conditions, the test method was based on the antimicrobial degree (KS K 0693-2001) method according to the Korean Industrial Standards, and the results tested by the method were as follows.

Test Items Example 1 BLANK Strain 1 Initial bacterial count 1.4 x 10 ⁵ 1.4 x 10 ⁵ 18 hours later 〈10 6.7 x 10 ⁶ Bacteriostatic reduction rate 99.9 - Strain 2 Initial bacterial count 1.6 x 10 ⁵ 1.6 x 10 ⁵ 18 hours later 〈10 7.5 x 10 ⁶ Bacteriostatic reduction rate 99.9 -

At this time, in the above test, BLANK means used as it is a natural cotton fabric without any water repellent treatment, such as bacteria, bacteria number / ml, bacteriostatic reduction rate is%.

Therefore, when the cotton fabric according to Example 1 is exposed to bacteria and 18 hours have elapsed, it can be confirmed that almost completely contaminated bacteria are removed, which is a decoupling of the bedding 100 according to the present invention. It was interpreted that the cotton fabric clearly demonstrated that it had high antimicrobial properties.

《Real contaminant removal performance [Ⅰ]: in case of coffee》

This experiment was carried out to check how much performance can be achieved in the situation where the cotton fabric for fastening of the bedding 100 according to the present invention actually hit in a general home. In this experiment, a sample pillow was made using the cotton fabric according to the present invention, an instant coffee was poured randomly onto the pillow, and then rubbed with a toilet paper in the state, followed by wiping it off. .

Figure 4 is a photograph taken in this order the experimental process. First, in a state of placing a pillow, one of the beddings 100 of the present invention on a desk (FIG. 4A), slowly poured instant coffee (FIG. 4B), and continued until the instant coffee was very hot. This lock was enough (FIG. 4C). After a while, it was absorbed by the instant coffee while slowly moving inward from the periphery with the cosmetic tissue (Fig. 4d), and was able to sufficiently absorb the cosmetic tissue with the cosmetic tissue (Fig. 4e), It was then allowed to absorb the instant coffee remaining on its surface (FIG. 4F). Then, the surface was finally wiped off with a tissue as a whole (Fig. 4g).

After this series of procedures, the pillow according to the present invention was restored to the state before the surface was contaminated with instant coffee, which can be clearly confirmed by the last drawing (Fig. 4g).

《Practical removal of contaminants [II]: Green juice》

This is in consideration of the fact that the inner fabric cotton fabric of the bedding 100 according to the present invention as the main component of the vegetable fiber, and experimented to check the possibility of contamination by vegetable green juice. In this experiment, the cotton fabric used for the bedding 100 of the present invention is laid out on a desk, and the freshly delivered green juice (100% of fresh leaf green juice made from true down health food) is poured on it in the morning, After a period of about 2 to 3 minutes, it was carried out by wiping it with rubbing with a cosmetic tissue in that state.

5 is a photograph taken in this order of the experimental process. First, the cotton fabric used in the beddings 100 of the present invention and the new green sec green juice and toilet paper were prepared (FIG. 5A), and then slowly poured the green sec green juice (FIG. 5B). At this time, it could be observed that the green grass green juice is droplets without spreading from the surface of the cotton fabric (Fig. 5c). After about 3 minutes in that state, the fresh green leaf juice was slowly absorbed from the heavily contaminated portion with a cosmetic tissue (FIG. 5D), and this operation was continued to remove the surface juice (FIG. 5E). Thereafter, the toilet paper absorbed the new green grass green juice and the new green grass green juice and the cotton fabric after the experiment were collected on a desk, and finally photographed to confirm this (FIG. 5F).

Likewise in the above experiment, the cotton fabric used in the bedding 100 of the present invention was confirmed that the contaminated area is also removed by the green juice freshly delivered in the morning. However, in the case of the coffee, when rubbing the surface with toilet paper, the original surface was immediately restored as it was, whereas in the case of the green juice, slightly light green was maintained by the first rub, and then rubbed 2-3 times. The only difference was that they both recovered the original surface.

This means that once a conventional natural cotton fabric is contaminated by the chloroplast component of the plant (e.g., lying on grass or contaminated by grass or fruit juice), the cotton fabric is removed afterwards. Given what couldn't be done, this is incredible.

As confirmed through such a series of processes, the bedding 100 according to the present invention is very excellent in water repellency and oil repellency even in a practical situation, moreover, it is excellent in antifouling properties for natural green juice as cotton fabric It is considered an aspect that no one can expect.

The bedding 100 according to the present invention is the fabric for the fabric 120 is composed of a natural cotton fabric 122, the film by the polyurethane adhesive layer 124 and the perfluorinated polymer on one side or both sides thereof. Since the layer 126 is included, even if water, milk, coffee, green juice, or the like spills and contaminates due to various reasons, the water repellency, oil repellency, and antifouling properties are very excellent.

Therefore, when the bedding 100 according to the present invention is contaminated from various substances containing moisture or contaminated from oil-containing substances, the fabric for the fabric is held in one hand on the spot and the contaminants are turbid. It is good enough to shake off, and there is no need to perform another separate operation.

In addition, the bedding 100 according to the present invention does not penetrate the cotton or filling material contained therein even when exposed to a pollutant, so that the problem of having to dry or wash it cumbersomely as in the past There is also an advantage that can be solved.

Although the beddings according to the present invention have been described in detail above, this is only for describing the most preferred embodiments of the present invention, and the present invention is not limited thereto, and the scope thereof is determined by the appended utility model registration claims. Become limited. In addition, anyone of ordinary skill in the art will be able to make various modifications and imitations according to the description of the specification of the present invention, but it will be apparent that this is also outside the scope of the present invention.
