Description

The present invention relates to a pouch that can be washed in a household washing machine or a shower in a bathroom, a pouch cover bag that houses the pouch and allows allergens to be sucked out with a vacuum cleaner, and bedding using these.

It is known that mites easily propagate in bedding such as pillows and futons, and that a person inhales the living body, carcass or feces of the mites as an allergen, causing asthma, nasal allergy and the like. As a method of controlling mites, the allergen inside can be sucked and removed from the top of the duvet cover with a vacuum cleaner, but it is difficult to suck the living body of mites from the texture of the bedding. In addition, the bedding itself is bulky and cannot be put in a household washing machine, and if the cotton or the like inside the bedding is wet, it takes time to dry it. Therefore, the invention disclosed in Patent Document 1 proposes a bedding cover capable of suppressing the passage of allergens such as mites. This bedding cover has a bag-shaped structure made of a sheet-like cloth that does not allow ticks to pass through. It has a seal chuck with a structure that opens and closes. This double or more fastener makes it possible to more reliably suppress the passage of mites.

Japanese Patent No. 2009-95474

However, since the bedding cover cover material proposed in Patent Document 1 is made of a material that restricts the passage of allergens such as mites (generally, a size of 10 to 20 μm), the fastener is intentionally opened. Allergens can get inside the bedding cover when or when it is opened unexpectedly. Once the cover contains house dust containing living organisms of mites, their feces, and carcasses, there is a problem that it is difficult to remove them.

The pouch of the present embodiment has a first layer having a water-repellent function, a second layer provided on the back surface of the first layer, and a third layer provided on the back surface of the second layer and having a waterproof function. It has a layer and a pouch outer fabric containing. And it is equipped with a filling object, which is wrapped in the outer fabric of the pouch. The outer fabric of the pouch has a first ventilation hole having a hole diameter of 1 μm to 5 μm.

The water repellency of the outer pouch fabric has a water repellency of grade 4 or higher according to JIS L 1092-2009 7.2. The waterproof function of the outer fabric of the pouch is water pressure resistance of 500 mm or more. It is preferably 800 mm or more. The air permeability through the first ventilation hole is 200 to 10 (cc / cm2 · s) according to JIS L 1096 (Frazil type air permeability test). Further, the filling object is packed in the pouch inner fabric arranged inside the pouch outer fabric, and a part of the pouch inner fabric is sewn on the pouch outer fabric.

The pouch cover bag of the present embodiment houses the first pouch and the second pouch. The pouch cover bag is a first cover that separately stores the first cover side fabric and the second cover side fabric having a second ventilation hole of 0.5 mm square to 5.0 mm square, and the first pouch and the second pouch. A partition fabric joined to the side fabric and the second cover side fabric is provided. The surface of the first cover-side fabric or the second cover-side fabric that comes into contact with the first pouch or the second pouch is anti-slip processed.

In the pouch cover bag of the present embodiment, since the pouch is taken in and out of the storage space formed by the first cover side fabric and the second cover side fabric, at least one of the first cover side fabric and the second cover side fabric is open. It has a portion and has a sealing means for sealing the opening.
Further, the first pouch and the second pouch are rectangular in a plan view, and the partition fabric is a cross-sectional view so that a part of the long side of the first pouch and a part of the long side of the second pouch overlap each other. It is joined to the first cover side fabric and the second cover side fabric so as to be slanted at.

In the pouch of this embodiment, the living body and carcass of mites, allergens of excrement, human dandruff, skin pieces, dust, etc., which are mites' favorite foods, do not reach the clogged object, and water droplets such as a shower do not reach the clogged object. Does not reach.
The pouch cover bag of this embodiment has a second ventilation hole of the cover bag sufficiently larger than the size of the allergen. Therefore, the vacuum cleaner makes it easy to suck allergens and the like that have entered the cover bag and adhered to the surface of the pouch to the outside of the cover bag through the second ventilation hole of the cover bag.

<Regarding comforter 10>

FIG. 1 is a perspective view showing a comforter 10 according to the present embodiment. The comforter 10 has a rectangular parallelepiped shape, and is used so that the user is in a lying position (supine position) with the head side in the + X-axis direction and the leg side in the −X-axis direction. The pouch cover bag 12Q of the comforter 10 has a first cover side fabric 12a that covers the front surface (first main surface) of the rectangular parallelepiped pouch 40 (see FIGS. 2 and 4) and the back surface (second main surface) of the pouch. It has a second cover side fabric 12b that covers the surface.

The first cover side fabric 12a and the second cover side fabric 12b of the pouch cover bag 12Q have a rectangular shape, and are 0.5 mm to 5.0 mm of cotton, linen, rayon, silk, wool, nylon, acrylic, polyurethane, polyester, etc. It is a mesh material having a degree of mesh. A blended material in which a non-slip material such as polyurethane having a non-slip function is combined may be used, or the mesh material may be given moisture absorption / desorption. Since the first cover-side fabric 12a and the second cover-side fabric 12b come into contact with the skin of the user's neck, arms, etc., it is preferable that the first cover-side fabric 12a and the second cover-side fabric 12b are soft to the touch and excellent in hygroscopicity. The first cover side fabric 12a and the second cover side fabric 12b of the pouch cover bag 12Q are formed with a gusset. Although the explanation is given below with a gusset, it is not necessary to provide a gusset.

The fabrics of the first cover side fabric 12a and the second cover side fabric 12b are formed of a coarse mesh. The main producers of house dust derived from mites that cause mite allergies are gout mite and mite mite, and since the living body is about 0.4 mm, the first mesh cover side fabric 14a is equivalent to 0.5 mm square or more. It is preferable that the size of the eyes (second ventilation hole) is. The larger the mesh (second ventilation hole), the easier it is to suck in allergens, but since it is necessary to use a backing cloth when sewing, the mesh can be directly sewn with a mesh of about 3.0 mm to 5.0 mm. It is possible to reduce the cost by using. The user uses the vacuum cleaner head NZ of the vacuum cleaner VC to remove allergens such as dust and mite carcasses on the surface (+ Z direction side) of the pouch 40 from the first cover side fabric 12a or the second cover side fabric 12b. Can be sucked through the mesh of. In other words, the user can inhale allergens such as dust and mite carcasses on the surface (+ Z direction side) of the pouch 40 without removing the pouch 40 from the comforter 10.

In the present embodiment, since the pouch cover bag 12Q is a coarse mesh, by sucking through the pouch cover bag 12Q, it is possible to prevent sucking the dough of the pouch cover bag 12Q while effectively sucking the allergen, and the vacuum cleaner head NZ. Can be easily removed. As a result, the user can quickly and easily perform a wide range of suction of the pouch cover bag 12Q.

<Regarding Pouch Cover Bag Example 1>
FIG. 2 is a diagram showing the comforter 10, and is an example in which the pouch cover bag 12Q of the first embodiment is used. FIG. 2A is a plan view of the comforter 10, and three pouches 40 are drawn by a two-dot chain line. FIG. 2B is a sectional view taken along the line BB of FIG. 2A. 2 (C) is an enlarged cross-sectional view of the circled area of FIG. 2 (B), and FIG. 2 (D) is an enlarged cross-sectional view of the circled area of FIG. 2 (B). It is a figure.

The comforter 10 is for single use, for example, and has a long side direction (X-axis direction) of 210 cm and a short side direction (Y-axis direction) of 150 cm. It can be a large size such as a semi-double or double size, or it may be a small size for infants or children. Further, although the present embodiment is described by the example of three pouches 40, two pouches or four or more pouches may be used. When making a mattress or a kotatsu mattress, the size suitable for each may be adopted.

The first cover side fabric 12a, which is the front side of the pouch cover bag 12Q, has three openings 12c. Three pouches 40 are housed in the comforter 10 through the three openings 12c. As can be understood from FIG. 2A, the opening 12c is formed on the short side (Y-axis direction) of the comforter 10 with a length of 80% to 100% of the short side length. The opening 12c is formed to be equal to or slightly shorter than the long side (Y-axis direction) of the pouch 40 so that the user can easily store the pouch 40 in the comforter 10.

The sealing means 20 is provided so as to close the opening 12c. The sealing means 20 is, for example, a metal or resin fastener, and the metal or resin fastener has a slider 22 and a zip 24. The fastener shown in FIG. 2 (A) has two sliders 22 to improve convenience so that it can be opened and closed from any position in the short side direction (Y-axis direction), but only one slider 22. May be good. In addition to the metal or resin fastener, as the sealing means 20, a snap button composed of a convex button and a concave button, a hook-and-loop fastener having a plurality of hooks and loops, and the like can be used. Further, the width of the opening 12c in the short side direction (Y-axis direction) is narrowed to, for example, about 70 cm, the pouch 40 is folded so as to be stored from the opening 12c, and the pouch 40 is stored in the Y-axis direction after storage. You may store it so that it can be spread out and fastened.

At the four corners of the comforter 10, slip prevention strings 18 for fastening the comforter cover (not shown) and the comforter 10 are provided. In FIG. 2A, four slip prevention strings 18 are provided, but further, slip prevention strings 18 are provided near the center of each of the two long sides (X-axis direction) of the comforter 10, for a total of six slips. The prevention string 18 may be provided. The comforter 10 does not necessarily require a comforter cover, but is provided by the user for a user who wants to cover the comforter 10 with a comforter cover to prevent touch and dirt.

As shown in FIG. 2B, the second cover side fabric 12b, which is the back side of the comforter 10, is not provided with the sealing means 20. If the comforter 10 is turned upside down, the user can suck allergens such as dust and dead mites on the back surface (-Z direction side) of the pouch 40 through the second ventilation hole.

Further, the three pouches 40 are individually stored in the comforter 10 so as not to move unnecessarily in the comforter 10. Two partition fabrics 12d are provided in the X-axis direction so that the three pouches 40 are individually stored. For example, when the long side (X-axis direction) of the comforter 10 is 210 cm and the pouch 40 of the same size is stored, the length in the X-axis direction is 70 cm. The partition fabric 12d is sewn (joined) to the first cover side fabric 12a and the second cover side fabric 12b. As can be understood from FIG. 2B, the joining positions of the first cover side fabric 12a and the partition fabric 12d are the second cover side fabric 12b and the partition fabric 12d when viewed from the normal direction (Z-axis direction). The partition cloth 12d is diagonally arranged in a cross-sectional view, which is different from the joining position of.

As a result, the end portions 40p of the adjacent pouches 40 overlap each other. For example, when the long side (X-axis direction) of the comforter 10 is 210 cm, the distance from the joint position between the first cover side fabric 12a and the partition fabric 12d to the joint position between the second cover side fabric 12b and the partition fabric 12d is It is about 10 cm to 40 cm, preferably 20 cm to 30 cm. As a result, the end portions 40p of the adjacent pouches 40 overlap each other by about 5 cm to 35 cm. For example, if the adjacent pouches 40 do not overlap and there is a gap in the X-axis direction, the user may feel cold. That is, the end portions 40p of the adjacent pouches 40 do not overlap each other and impair the heat retention property. The partition fabric 12d is preferably anti-slip processed.

Further, the joint position between the first cover side fabric 12a and the partition fabric 12d is preferably in the + X axis direction (head side), and the joint position between the second cover side fabric 12b and the partition fabric 12d is in the −X axis direction (leg portion). Side) is preferred. This is because even if the user moves the legs while sleeping, the pouch 40 does not move toward the legs (-X-axis direction) by kicking the end 40p of the pouch 40 on the leg side.

FIG. 2C is an enlarged cross-sectional view of the second cover side fabric 12b and the pouch 40. As described above, the first cover side fabric 12a and the second cover side fabric 12b are made of a mesh material such as cotton, linen, rayon, silk, wool, nylon, acrylic, polyurethane or polyester, and polyurethane having a non-slip function or the like. A case where a blended material in which a non-slip material is combined is used will be described. As shown in FIG. 2C, the non-slip material 12h is arranged on the side of the second cover side fabric 12b in contact with the pouch 40, and the mesh material 12k is arranged on the opposite side (the side in contact with the user's body). Will be done. In the present embodiment, when a woven fabric is woven from a blended yarn of a yarn of a mesh material and a yarn of a non-slip material, the mesh material 12k is arranged on one side and the non-slip material 12h is arranged on the other side. .. However, the side fabric may be woven only with the thread of the mesh material 12k, the side fabric may be woven only with the thread of the non-slip material 12h, and the side fabric may be created by combining them. Since the non-slip material 12h of the second cover side fabric 12b is in contact with the pouch 40, the pouch 40 is difficult to move even if the user moves the legs or the like while sleeping. Therefore, the state in which the three pouches 40 are stored can be maintained as they are.

Although an enlarged cross-sectional view of the first cover side fabric 12a and the pouch 40 is not shown, the non-slip material 12h may be provided on the side in contact with the pouch 40, as in the case of the second cover side fabric 12b. Further, if the first cover side fabric 12a and the second cover side fabric 12b have the non-slip material 12h, the pouch 40 becomes more difficult to move even if the user moves the legs or the like while sleeping.

FIG. 2D is an enlarged cross-sectional view of the partition fabric 12d and the pouch 40. The partition fabric 12d is made of a material such as cotton, linen, rayon, silk, wool, nylon, acrylic or polyester. A blended material in which a non-slip material such as polyurethane having a non-slip function is combined may be used, or a material having moisture absorption / desorption may be used. In this embodiment, a case where anti-slip processing is applied will be described. As shown in FIG. 2D, the partition fabric 12db has the non-slip material 12h arranged on both sides in contact with the pouch 40, and the mesh material 12k arranged in the center. In the present embodiment, when a woven fabric is woven from a blended yarn of a yarn of a mesh material and a yarn of a non-slip material, the mesh material 12k is arranged in the center and the non-slip material 12h is arranged on both sides. Is preferable. However, the side fabric may be woven only with the thread of the mesh material, and the side fabric may be woven only with the thread of the non-slip material to create a fabric combining them.

If the adjacent pouches 40 do not overlap and a gap is created in the X-axis direction, the user may feel cold. It is preferable that the anti-slip processing is applied. Although not shown in particular, one of the hook-and-loop fasteners is placed on the end 40p of the pouch 40, and the other of the hook-and-loop fasteners is placed on the partition fabric 12d made of only mesh material, and the end 40p of the pouch 40 is non-slip processed. Alternatively, you may use a snap button or the like to prevent it from moving. In such a case, only the mesh material 12k may be used.

<Regarding Pouch Cover Bag Example 2>
FIG. 3 is a diagram showing the comforter 10 and shows the pouch cover bag 12R. The position of the sealing means 20, the region of the non-slip material 12h of the first cover side fabric 12a or the second cover side fabric 12b, and the presence / absence of the slip prevention string 18 are different from the pouch cover bag 12Q of FIG. Hereinafter, the differences from the pouch cover bag 12Q shown in FIG. 2 will be described, and the description of the same structure will be omitted.

FIG. 3A is a plan view of the comforter 10, and three pouches 40 are drawn by a two-dot chain line. FIG. 3B is a cross-sectional view taken along the line BB of FIG. 3A (a part thereof is not a cross section but a side view). 3 (C) is an enlarged cross-sectional view of the circled area of FIG. 3 (B), and FIG. 3 (D) is an enlarged cross-sectional view of the circled area of FIG. 2 (B). It is a figure.

The pouch cover bag 12R has three openings 12c on the side surface of the long side on which the first cover side fabric 12a and the second cover side fabric 12b are sewn. Three pouches 40 are housed in the comforter 10 through the three openings 12c. As can be understood from FIG. 3B, the opening 12c is formed on the long side (X-axis direction) of the comforter 10 with a length of 80% to 100% of the short side length of the pouch 40.

The sealing means 20 is provided so as to close the opening 12c. The sealing means 20 is, for example, a metal or resin fastener, and the metal or resin fastener has a slider 22 and a zip 24. The fastener shown in FIG. 3B has one slider 22. As the sealing means 20, a snap button composed of a convex button and a concave button, a hook-and-loop fastener having a plurality of hooks and loops, and the like can be used. Although the sealing means 20 is arranged only on the right side in FIG. 3A, the sealing means 20 is arranged on the left side so that the pouch 40 can be put into the pouch cover bag 12R from either the left or right side. You may.

At the four corners of the comforter 10, slip prevention strings 18 for fastening the comforter cover (not shown) and the comforter 10 are not provided. This is because the pouch cover bag 12R itself is soft to the touch and can be easily washed even if it gets dirty, and acts as a comforter cover.

Further, the three pouches 40 are individually stored in the comforter 10 so as not to move unnecessarily in the comforter 10. Two partition fabrics 12d are provided at equal intervals in the X-axis direction so that the three pouches 40 are individually stored. It is the same as the pouch cover bag 12Q in that the partition cloth 12d is diagonally arranged in a cross-sectional view.

3 (C) is a cross-sectional view of the right side region of FIG. 3 (A), as can be seen from the BB cross section of FIG. 3 (A). In the right side region (light-colored region) of FIG. 3A, only the mesh material 12k is arranged on the second cover side fabric 12b. This is because when the user opens the sealing means 20 and stores the pouch 40 from the opening 12c, if the non-slip material 12h is present, it is difficult to insert the pouch 40 all the way to the back (+ Y-axis direction).

3 (D) is a cross-sectional view from the central region to the left side region of FIG. 3 (A), as can be seen from the BB cross section of FIG. 3 (A). In the left side region (dark region) of FIG. 3A, the mesh material 12k and the non-slip material 12h are arranged on the second cover side fabric 12b. When the non-slip material 12h comes into contact with the pouch 40, the pouch 40 becomes difficult to move.

Although an enlarged cross-sectional view of the first cover side fabric 12a and the pouch 40 is not shown, in the right side region (light color region) of FIG. 3A, as in the second cover side fabric 12b, the first cover side fabric 12a is shown. 2 It is preferable that only the mesh material 12k is arranged on the cover side fabric 12a. Further, in the left side region (dark region) of FIG. 3A, it is preferable that the mesh material 12k and the non-slip material 12h are arranged on the second cover side fabric 12a. Further, although not shown in FIG. 3, in a structure in which the sealing means 20 is arranged on both the left and right sides, it is preferable that the non-slip material 12h is arranged only in the central region.

<About the pouch>
FIG. 4 is an embodiment of the pouch 40 housed in the pouch cover bag 12. 4 (A) is a plan view of the pouch 40, and FIG. 4 (B) is a sectional view taken along the line BB of FIG. 4 (A). 4 (C) is an enlarged cross-sectional view of the left edge region of the pouch 40 circled in FIG. 4 (B), and FIG. 4 (D) is a circled pouch in FIG. 4 (B). This is another example of the left edge region of 40. FIG. 4C is an enlarged view of sealing the needle hole using the hot melt adhesive ad, and FIG. 4D is an enlarged view of sealing the needle hole using the seam tape st.

The rectangular parallelepiped pouch 40 functions as a heat insulating material for the comforter 10. One pouch 40 has, for example, a length of 70 cm in the X-axis direction, a length of 150 cm in the Y-axis direction, and a height of 10 cm in the Z direction. As shown in FIG. 4A, the edges of the upper and lower pouch outer fabrics 45 are sewn on the pouch 40. In FIG. 4A, the two edges of the long side of the pouch outer fabric 45 are sewn with a hot melt sandwiched between them, and then the needle holes for sewing are closed by heat welding. Turn it over to form the edge 47c. The user cannot directly see the edge 45c and cannot directly touch it. The short side of the pouch outer fabric 45 is also sewn. As will be described later, the edge of the short side of the pouch outer fabric 45 is an edge 47a sewn together with a tongue piece (see FIG. 4C or FIG. 4D) so that the content 42 does not shift in position. This edge 47a can be touched directly. In the present embodiment, aesthetically, the edges of the two short sides are on the outside (can be directly touched), but all the sewn edges may be arranged on the outside, or one sewn edge is sewn. The edges may be placed on the outside.

As shown in FIG. 4B, the pouch 40 includes a pouch outer fabric 45 and a content 42 inside the pouch outer fabric 45. The content 42 is composed of a pouch inner fabric 42c and a filling object (so-called batting) 42i packed in the pouch inner fabric 42c. In this packed object 42i, the comforter 10 has a shape that rises in the Z-axis direction. It is preferable to have a structure in which mites, their feces, and carcasses do not enter the inside of the pouch outer fabric 45.

The fabric 42c in the pouch is, for example, a mesh material such as cotton, linen, rayon, silk, wool, nylon, acrylic or polyester, or a blended material in which two or more of them are combined. Further, the fabric 42c in the pouch can be changed to a non-woven fabric.

The filling object 42i is, for example, cotton, cotton, polyester cotton, acrylic resin cotton, feathers (feathers), wool, etc., and the type of the content 42 is not limited to cotton, but is not limited to cotton, and acrylate fibers (water-absorbing heat generators) or air pads. (Sheet that traps air) can be changed as appropriate.

As shown in FIG. 4B, the short sides on both sides of the content 42 are sewn on the pouch outer fabric 45 so that the content 42 does not shift in position. If the volume of the content 42 does not change even after long-term use, the content 42 may not be sewn on the pouch outer fabric 45. In the present embodiment, the volume of the content 42 is substantially the same as the volume formed by the pouch outer fabric 45, but when the filling object 42i shrinks due to long-term use, the content 42 becomes the pouch outer fabric 45. It prevents it from moving in the space formed by.

FIG. 4C is an enlarged cross-sectional view of a state in which the short side of the content 42 and the short side of the pouch outer fabric 45 are sewn, and is the first example. To aid understanding, FIG. 4 (C) is drawn with each member separated. On both side short sides of the content 42, the upper and lower short sides of the pouch inner fabric 42c are sewn with the sewing thread tr, and further, the tongue piece 43 is sewn on the pouch inner fabric 42c with the sewing thread tr. Further, the short side of the upper pouch outer fabric 45 and the short side of the lower pouch outer fabric 45 are folded in half to prevent fraying, and the hot melt adhesive ad is applied to the short side of the upper pouch outer fabric 45. And along the short side of the lower pouch outer fabric 45, respectively. The hot melt adhesive ad melts at 150-180 ° C. The tongue piece 43 is placed between the two layers of hot melt adhesive ad. Then, the short sides of the upper and lower pouch outer fabrics 45 and the tongue piece 43 are sewn with the sewing thread tr. After that, the hot melt adhesive ad is melted and pressed by a heater such as an iron, and the hot melt adhesive ad seals the needle hole formed by the sewing thread tr. This completes the edge 47a, from which mites, their feces, and carcasses do not enter.

FIG. 4D is an enlarged cross-sectional view of the short side of the content 42 and the short side of the pouch outer fabric 45, and is the second example. In the first example of FIG. 4C, the hot melt adhesive ad was melted and the needle hole formed by the sewing thread tr was sealed. Further, the tongue piece 43 is sewn on the fabric 42c in the pouch. In FIG. 4D, the seam tape st is used to seal the needle hole formed by the sewing thread tr. Further, at least one of the upper and lower parts of the pouch inner fabric 42c is long, and the tongue pieces of the pouch inner fabric 42c are sewn on the upper and lower pouch outer fabrics 45.

In FIG. 4D, the short side of the upper pouch outer fabric 45 and the short side of the lower pouch outer fabric 45 are folded inward in half to prevent fraying, and the tongue piece of the elongated pouch inner fabric 42c is formed. Is sewn with the sewing thread tr. The sewn area is hem-wound with a seam tape st, and the hem-wound peripheral edge is heated and pressed at 150 to 180 ° C. The needle hole is sealed by melting the resin seam tape st by this high temperature pressurization. Therefore, allergens such as mites and their feces do not invade the inside of the pouch outer cloth 45 from the needle hole. The seam tape st is a ribbon of a resin that melts under high temperature pressure, for example, EVA (ethylene vinyl acetate copolymer).

In this embodiment, the contents 42 (the pouch inner dough 42c and the filling object 42i) are contained inside the pouch outer dough 45 for ease of manufacturing. However, the structure may be such that the inner fabric 42c of the pouch is eliminated and the filling object 42i such as cotton is directly put inside the outer fabric 45 of the pouch.

FIG. 5A is a cross-sectional view taken along the line AA of FIG. 4A, which is an enlarged cross-sectional view of the long side of the content 42 and the long side of the pouch outer fabric 45. To aid understanding, FIG. 5 (A) is drawn with each member separated. The long side of the upper pouch outer fabric 45 and the long side of the lower pouch outer fabric 45 are folded in half to prevent fraying, and the hot melt adhesive ad is applied to the long side and the lower side of the upper pouch outer fabric 45. It is arranged between the long side of the pouch outer fabric 45 on the side. Then, the long sides of the upper and lower pouch outer fabrics 45 are sewn with the sewing thread tr, the hot melt adhesive ad is melted and pressed by the heating and pressurizing device, and the needle holes formed by the sewing thread tr are sealed. After that, the upper pouch outer fabric 45 and the lower pouch outer fabric 45 are turned inside out, thereby completing the edge 47c. Allergens such as mites and their feces and carcasses do not enter from this edge 47c.

FIG. 5B is an enlarged cross-sectional view of the pouch outer fabric 45 circled in FIG. 4B.
The pouch outer fabric 45 is composed of a water-repellent layer 45p, an outer fabric layer 45q, and a waterproof layer 45r from the outside. The outer fabric layer 45q of the pouch outer fabric 45 is preferably formed of a high-density woven fabric or a high-density non-woven fabric through which live mites do not pass and allergens in which dead bodies such as mites have become finer do not pass. For example, a high-density woven fabric is a fabric in which about 380 threads (about 220 vertical x 160 horizontal) are woven with 50 denier threads in a 1-inch weft. It consists of fibers that are difficult for finer particles to pass through. For example, the outer fabric layer 45q has a first ventilation hole having a hole diameter of 1 μm to 5 μm after being water-repellent (water-repellent layer 45p) and waterproof (waterproof layer 45r). 1 The hole diameter of the ventilation hole is large enough to allow air to pass through but not to allow water droplets or the like to pass through. The outer fabric layer 45q is made of a material such as cotton, linen, rayon, wool, acrylic, nylon or polyester, or a blended material obtained by combining two or more of them, as the material of the high-density woven fabric or the high-density non-woven fabric. The pouch outer fabric 45 is hard and uncomfortable to the touch when it is a high-density woven fabric or a high-density non-woven fabric, but the user does not feel so uncomfortable because the user's skin does not come into direct contact with the fabric. Since the pouch outer fabric 45 is made of a high-density woven fabric or a high-density non-woven fabric, human dandruff, skin pieces, dust, etc., which are preferred by allergens and mites, do not enter the inside of the pouch 40.

The water-repellent layer 45p of the pouch outer fabric 45 is coated with a PFOA (perfluorooctanoic acid) -free short-chain fluorine (carbon number 6 or less, commonly known as C6, C4, etc.) processing agent on the outer surface of the outer fabric layer 45q. It is formed. These water-repellent processing agents are provided by companies such as Teijin Frontier, Komatsu Seiren, and Toyobo STC. The pouch outer fabric 45 of the present embodiment is JIS L 1092-2009 7.2, which is grade 4 (not wet on the surface but showing adhesion of small water droplets) or grade 5 (no wetness or adhesion of water droplets on the surface). It is preferable that it has a water-repellent function.

In the waterproof layer 45r of the pouch outer fabric 45, the fluorine agent is directly immersed in the inner surface of the outer fabric layer 45q, and after the fluorine agent has spread to the inside of the outer fabric layer 45q and the fibers, a special solvent is applied in a state of being dried to some extent. It is formed by spraying. By spraying the special solvent, the pouch outer fabric 45 has a pore size of 1 μm to 5 μm. The waterproof layer 45r (state in which the water-repellent layer 45p is not formed) of the pouch outer fabric 45 preferably has a water pressure resistance of 300 to 500 mm or more. The water pressure resistance of 500 mm means that even if water is placed on the pouch outer fabric 45 having the waterproof layer 45r to a height of 500 mm per unit area, the water does not leak below. The pouch outer fabric 45 of the present embodiment has a water pressure resistance of 500 to 800 mm or more due to the combination of the water repellent function of the water repellent layer 45p and the waterproof function of the waterproof layer 45r.

Since the pouch outer fabric 45 having the water-repellent layer 45p and the waterproof layer 45r has a pore size of 1 μm to 5 μm, it is 200 to 10 (cc / cm2. It has the air permeability of s). It preferably has a breathability of 50 to 20 (cc / cm2 · s). Even if steam such as sweat generated while the user is sleeping or moisture in the air enters the inside of the pouch outer fabric 45, the steam or moisture can be removed by drying the pouch 40 with a household dryer or the like. Go outside 45.

Since the pouch 40 of the present embodiment has the functions and structures described with reference to FIGS. 4 and 5, the user can wash and dry the pouch 40 at home. More specifically, the user can take out the pouch 40 from the pouch cover bag 12, shower the pouch 40 to wash sweat and allergens on the surface of the water-repellent layer 45p, and then shake the pouch 40. Water droplets fly from the water-repellent layer 45p and can be easily dried. Further, if the pouch 40 is, for example, 70 cm × 150 cm × 18 cm, it can be put in a household washing / drying machine, so that the user can dry and remove mites with the household washing machine. Even if the function of the water-repellent layer 45p deteriorates due to long-term use, since there is a waterproof layer 45r, water droplets such as a shower do not reach the clogged object.
