[0010] The hair cap according to the present invention will be described below with reference to the drawings. However, the present invention is not limited to the embodiments shown below, and can be modified, added, altered, or deleted to the extent that a person skilled in the art can conceive of it. Any embodiment that achieves the function and effect of the present invention is included within the scope of the present invention.

[0011] <Hair cap> The hair cap of this invention is A hair cap having a main body with openings at both ends, a first string provided at one opening of the main body, and a second string provided at the other opening of the main body, The main body has openings at both ends designated as a first opening and a second opening, with a first insertion portion through which the first string portion is inserted into the first opening, and a second insertion portion through which the second string portion is inserted into the second opening. The first insertion portion and the second insertion portion are formed such that both ends of the corresponding cord portion extend outwards. The size of the first opening can be changed by pulling one end and / or the other end of the first string part, and the size of the first opening is fixed by tying one end and the other end of the first string part, The size of the second opening can be changed by pulling one end and / or the other end of the second string part, and the size of the second opening is fixed by tying one end and the other end of the second string part, The first opening or the second opening is brought into contact with the wearer's head, and one end and the other end of the first string part or the second string part are pulled and tied, so that the hair cap is configured to be wearable on the wearer's head It is characterized in that.

[0012] According to the present invention, it is possible to provide a hair cap that is easy to wear, can reduce wearing marks, and can reduce foreign body sensation during use. A string part is provided at the opening, and the hair cap can be worn by tying the string part, so that ease of wearing is obtained. In addition, it is only necessary to tie the string part to fix it to the head, fixing members such as rubber members, buttons, and hooks are not required, wearing marks can be reduced, and foreign body sensation during use can be reduced. By tying the string part firmly, difficulty in slipping off is obtained.

[0013] The hair cap of the present invention may also be referred to as a night cap, a cap member, or the like. The hair cap is assumed to be used during sleep, but is not limited thereto, and may be used when getting up or during activities. In consideration of the effect on hair, the hair cap of the present invention may also be referred to as a hair care cap or the like.

[0014] When the first string part and the second string part are described without distinction, they may be simply referred to as a string part. When the first opening and the second opening are described without distinction, they may be simply referred to as an opening. When the first insertion part and the second insertion part are described without distinction, they may be simply referred to as an insertion part.

[0015] <Description of each structure> The hair cap of the present invention has a main body part with both ends open, a first string part provided at one opening of the main body part, and a second string part provided at the other opening of the main body part. Figure 1 shows a front view (A), a rear view (B), and a side view (C) illustrating the hair cap of this embodiment. Note that the diagrams shown in Figure 1 are plan views of the hair cap when placed on a stand or the like. Figure 2 shows a schematic diagram (A) illustrating the opening of the hair cap of this embodiment, and schematic diagrams (B) and (C) illustrating the insertion part.

[0016] The main body 2 has openings at both ends, designated as a first opening 6a and a second opening 6b. The main body 2 has a shape with openings at both ends. The first string portion 3a is provided in the first opening 6a of the main body 2, and the second string portion 3b is provided in the second opening 6b of the main body 2. In the main body 2, the shape having openings at both ends may be referred to as a cylindrical shape, and the main body 2 in this embodiment may be described as a cylindrical shape with openings at both ends. However, the cylindrical shape only needs to have openings at both ends, and includes the example shown in Figure 6 described later. Furthermore, the first opening 6a and the second opening 6b in the main body 2 are not always open; for example, the openings close when the main body 2 is placed, and the user opens the openings by hand when attaching it. The statement that both ends are open could also be described as, for example, that the top and bottom of the main body are open.

[0017] The main body 2 has a first insertion section through which the first string portion 3a is inserted into a first opening 6a, and a second insertion section through which the second string portion 3b is inserted into a second opening 6b. The first and second insertion sections are formed such that both ends of the corresponding string portions extend outward. Figure 1 shows that both ends of each string portion extend outward. Figures 2(B) and (C) show enlarged schematic diagrams to explain the first insertion section 4a, and the illustration of the first string portion 3a is omitted. The first string portion 3a is stored inside the first insertion section 4a. Figure 2(B) is a schematic diagram of the exit of the insertion section as seen in a state similar to Figure 1(C), and Figure 2(C) is a schematic diagram of the exit of the insertion section as seen in a state similar to Figure 1(A).

[0018] Figure 3 is a diagram illustrating the insertion portion of the hair cap in this embodiment. The first string portion 3a within the first insertion portion 4a is shown by a dashed line. The second opening 6b, the second insertion portion 4b, and the second string portion 3b are similar, although they are not shown.

[0019] In this embodiment, for example, the first string extends approximately 8 cm from the first insertion portion, and the second string extends approximately 8 cm from the second insertion portion. The lengths of the first and second strings may be the same or different. The expression "the string extends from the insertion part" can also be expressed as, for example, "the string extends from the exit of the insertion part." In this case, for example, it would be appropriate to say that the string extends about 8 cm from the exit of the insertion part.

[0020] Such an insertion section can be made, for example, by folding and sewing the end of the main body. Figure 4 is a diagram illustrating an example of stitching and an example of creating a pass-through. The numerical values ​​shown are examples only and are not limiting. For example, the first insertion part 4a and the second insertion part 4b can be created by folding and sewing the end of the main body part 2 at a predetermined point. Considering that the cord part in this example is 2 cm long, the lengthwise distance in the illustrated example of the insertion part is 3 cm. The sewing positions for forming the insertion part are indicated by reference numerals 7a and 7b. The first insertion part 4a can be formed by sewing 7a, and the second insertion part 4b can be formed by sewing 7b. By creating the insertion part in this way, the insertion part becomes a cylindrical opening. Furthermore, the first fixing part 5a and the second fixing part 5b should be sewn together approximately 0.1 cm (1 mm) from the edge.

[0021] The insertion portion in this invention can be formed, for example, by sewing the main body at sewing positions 7a and 7b. It is preferable that such sewing (sewing at sewing positions 7a and 7b) is continuous without interruption. Such continuous sewing prevents fraying at the interrupted position and improves durability. If such sewing is interrupted, the length of the interrupted portion is preferably 5 cm or less, more preferably 3 cm or less, and even more preferably 1 cm or less. If the sewing at sewing positions 7a and 7b is interrupted and there is a section where the length of the interrupted portion exceeds 5 cm, it does not correspond to the first insertion portion 4a and the second insertion portion 4b.

[0022] Figure 9 is a schematic diagram illustrating Comparative Example 1, which is not included in the present invention. The main body 12 of Comparative Example 1 has a belt loop 13, through which the first string portion 3a is passed. The first string portion 3a is tied and secured to the user's head, but if the first string portion 3a shifts, the fit becomes poor and it becomes easy to fall off. In addition, it is necessary to attach the belt loop 13, which adds to the manufacturing process. Such a belt loop 13 does not correspond to the insertion portion in the present invention.

[0023] The hair cap of this embodiment is made by sewing, as shown in Figure 4, for example, and therefore does not form gathers, nor does it require sewing for gathering. As a result, it is less likely to leave marks when worn as a hair cap. The hair cap of this invention can be manufactured, for example, by cutting the main body, forming an insertion part, sewing the main body into a tubular shape, and inserting the string part to form a fixing part.

[0024] In this embodiment, the size of the first opening 6a can be changed by pulling one end and / or the other end of the first string portion 3a, and the size of the first opening 6a can be fixed by tying one end and the other end of the first string portion 3a together. To change the size of the first opening 6a, pull either one or both ends of the first string 3a. Pulling both ends of the first string 3a makes it easier to adjust the size of the first opening 6a. After adjusting the size of the first opening 6a, you can fix the size of the first opening 6a by tying one end of the first string 3a to the other end. The method of tying is arbitrary. A bow knot makes it easier to fix and release. The main body 2 has a first insertion portion 4a on the side of the first opening 6a, and the size of the opening is adjusted by the first string portion 3a inserted through the first insertion portion 4a. The size of the opening is fixed by tying the first string portion 3a, and the hair cap is attached. Therefore, fixing and attachment can be done using only the first string portion without using rubber members or the like.

[0025] Furthermore, because the string portion is inserted into the insertion portion and extends from the exit of the insertion portion, it has the advantage of being easy to tie and easy to attach. For example, if the string portion is located outside the main body instead of being inserted into the insertion portion, when the main body is attached to the user's head and the string portion is tied, the string portion tends to slip and becomes difficult to secure. For example, if a belt loop (which may also be called a belt loop) is attached instead of an insertion portion, and the string portion is passed through the belt loop and tied, this invention does not apply. When such a belt loop is used, the manufacturing process is complicated, the string portion tends to slip when attached, and the feeling of wearing it is reduced. In addition, the belt loop may cause a feeling of foreign body in the garment.

[0026] Figure 5 is a schematic diagram illustrating an example of a hair cap being worn. (A) is a view from the front, and (B) is a view from the rear at an angle. The insertion part is omitted from the diagram. An example of how to attach the cap is described below. For example, pass your hair through the first opening 6a and place the periphery of the first opening 6a against your forehead. With the extended side of the first string 3a facing your forehead, pull the first string 3a to narrow the opening of the first opening 6a, and then tie one end of the first string 3a to the other. This will allow you to attach the hair cap 1. If you pull the string tightly, the opening will become even narrower and less likely to come off. If you do not pull the string tightly, there will be more slack around the periphery of the opening, making it less likely to leave marks.

[0027] Similarly, the size of the second opening 6b and the second string portion 3b can be changed by pulling one end and / or the other end of the second string portion 3b, and the size of the second opening 6b can be fixed by tying one end and the other end of the second string portion 3b together. Fixing and attachment can be done using only the second string portion without using rubber members or the like.

[0028] As described above, the hair cap of this invention can be attached to the wearer's head by bringing the first opening 6a or the second opening 6b into contact with the wearer's head and pulling and tying one end of the first string portion 3a or the second string portion 3b together.

[0029] The main body 2 of this invention has an open shape at both ends. Because both ends are open, when using the hair cap, the user may attach it to their head using either the first opening 6a or the second opening 6b. Having two attachment sides allows the cap to be used continuously even if, for some reason, one side cannot be attached.

[0030] As shown in Figure 5(B), when wearing the device, it is preferable to keep the opening on the opposite side of the head of the main body 2 closed and tie the string. If the user has hair longer than the length of the main body 2 (for example, 70 cm or more), the opening on the opposite side of the head of the main body 2 may be opened, and the hair may be pulled out without bending it inside the main body 2. In this case, the hair will not be bent inside the main body 2, preventing the hair from developing a permanent bend. It also prevents damage caused by hair rubbing against itself. The present invention is not limited to these examples, and even if the user's hair is longer than the length of the main body 2, the opening on the opposite side of the head may be kept closed and the string may be tied.

[0031] In this invention, a string is inserted through the insertion part, and the size of the opening can be adjusted by pulling the string. Furthermore, the size of the opening can be fixed by tying the string, allowing the hair cap to be secured to the user's head. In conventional technology, the majority of the string portion is sewn to the main body, requiring the use of elastic materials or gathers, which often leaves marks on the head. In this invention, the string portion is inserted through an insertion section, and by tying the string, the hair cap can be secured to the head without using elastic materials or gathers, thus minimizing marks on the head. Furthermore, by having an insertion section, the hair cap can be secured to the head without using elastic materials or gathers, thus reducing the feeling of a foreign object when worn.

[0032] As shown in the side view of Figure 1(C), when the main body 2 is viewed from the side, it is preferable that the positions where both ends of the first string portion 3a extend and the positions where both ends of the second string portion 3b extend are located on the same side. This improves handling, such as making it easier to tie the strings.

[0033] The first cord portion 3a is sewn to the first insertion portion 4a on the opposite side of where it extends to form a first fixing portion 5a, and it is preferable that the cord portion 3a is fixed to the first insertion portion 4a by the first fixing portion 5a alone. Similarly, the second cord portion 3b is sewn to the second insertion portion 4b on the opposite side of where it extends to form a second fixing portion 5b, and it is preferable that the cord portion 3b is fixed to the second insertion portion 4b by the second fixing portion 5b alone. This prevents the cord from slipping out of the insertion point. If the string comes out of the insertion point, it creates the extra step of having to reinsert the string into the insertion point.

[0034] In the schematic rear view of Figure 1(B), the first fixing part 5a is shown, and the first string part 3a is fixed to the first insertion part 4a by the first fixing part 5a alone. Similarly, the second fixing part 5b is shown, and the second string part 3b is fixed to the second insertion part 4b by the second fixing part 5b alone.

[0035] Furthermore, since the first cord portion 3a is fixed to the first insertion portion 4a only by the first fixing portion 5a, the first cord portion 3a is not fixed to the first insertion portion 4a or the main body portion 2 in the region from the first fixing portion 5a to the position extending from it. As a result, the first insertion portion 4a can be made bellows-shaped in that region, making it easier to adjust the size of the opening of the first opening 6a. This makes it possible to achieve both the prevention of the first cord portion 3a coming off and the ease of adjusting the first opening 6a. The same applies to the second cord portion 3b, the second insertion portion 4b, and the second opening 6b.

[0036] The method for forming the first fixing part 5a and the second fixing part 5b can be selected as appropriate. For example, when forming them by sewing, a lockstitch, bar tack, etc., may be used. The first fixing part 5a may consist of, for example, one lockstitch, two lockstitches, or multiple lockstitches. Fewer lockstitches reduce the effort required for manufacturing. When forming by bonding, the adhesive used can be appropriately selected, and any known adhesive can be used. It is advisable to adjust the amount of adhesive to reduce the feeling of foreign matter. When forming by fusion, it is best to apply heat to fuse the cord portion and the insertion portion (part of the main body). Appropriate materials, temperatures, etc., should be selected for the fusion process.

[0037] The hair cap of this invention preferably does not have an elastic component. In this case, it is less likely to leave marks. An example of an elastic component is a rubber component. In particular, it is preferable that it can be attached to the user's head without using a rubber component. By not having an elastic component, it is possible to further prevent marks from being left and to further reduce the feeling of a foreign object during use. In addition, by not having gathers and fastening members such as hooks and buttons, it is possible to further prevent marks from being left and to further reduce the feeling of a foreign object during use.

[0038] Furthermore, the hair cap of this invention does not need to have any fastening members (which may also be called fixing members) such as buttons. By not having fastening members, marks are less likely to be left, and the feeling of a foreign object can be further reduced. The hair cap of this invention can be secured to the head by tying the strings only. The hair cap of this embodiment does not use any rubber or buttons, and is structured to be secured to the head and to be adjusted in size (to accommodate hair length and head size) using only the strings.

[0039] <Size and shape of the main body> The shape of the main body can be selected as appropriate. As in this embodiment, the planar shape may be rectangular, or it may be other shapes. As in this embodiment, if it is a rectangle with long and short sides, it can accommodate long hair when used as a hair cap. For example, a size of 70cm x 50cm can be made appropriate. By making the length about 70cm, it can accommodate long hair without being too long. By making the width about 50cm, it can be prevented from becoming difficult to handle.

[0040] In this embodiment, the direction from the first opening 6a to the second opening 6b of the main body 2 is defined as the length direction, and the direction perpendicular to the length direction is defined as the width direction. When the length of the main body is referred to, it means the length direction, and when the width of the main body is referred to, it means the width direction. For example, in this embodiment, the length of the main body may be about 70 cm, and the width may be about 50 cm. Although not particularly limited, the length of the main body may be, for example, 50 cm to 100 cm. The width of the main body may be, for example, 40 cm to 60 cm. In this range, handling when using the hair cap is improved.

[0041] The planar shape of the main body 2 may be other than a rectangle, such as an ellipse, circle, or trapezoid. Furthermore, the corners of the rectangle or other shape may have a rounded (curved) shape.

[0042] Figure 6 is a schematic plan view illustrating another example of the main body 2. For example, the length may be shortened as in (A). In this case, the size will be suitable for users with short hair. The size of the main body (length and width) may be changed according to the user's hair length, head size, etc. In addition, the corners may be rounded, for example, as shown in (B1) and (B2). (B1) is a plan view when the string is positioned in the center, and (B2) is a plan view when the string is positioned on the left. In addition, the curved shape may be changed, for example, as shown in (D). In addition, the sizes of the first and second openings may be changed, for example, as in (C1) and (C2). For example, this makes it easier to use for multiple users with different head sizes. The choice of which of the first and second openings to attach to the head can be selected as appropriate. Alternatively, for example, the corners of (C1) may be rounded, as in (E). Alternatively, for example, as in (F), the width of the central part of the main body may be reduced. The example shown in Figure 6 is one in which the main body has a cylindrical shape.

[0043] The main body 2 may be decorated with frills, embroidery, lace, or other embellishments. Adding frills or other embellishments to the main body improves its appearance. When adding frills or other embellishments to the main body, it is best to place them in a position that does not come into contact with the face when the hair cap of this invention is used as a pillowcase, for example, around the insertion area.

[0044] <Effects of using a hair cap on hair> The hair cap of this invention, when worn on the head, provides one or more of the following effects on the hair: it can prevent bedhead, reduce dryness, improve manageability, make hair softer, make hair smoother, make hair more manageable, add shine, and reduce hair damage.

[0045] The main body of this embodiment is preferably made of silk. There are different types of silk, and in particular, it is preferable to use 6A grade silk in this invention. Using 6A grade silk improves the effects on the hair as described above. It is preferable to use high-grade 6A grade silk, and among 6A grade silk, to use silk that has obtained OEKO-TEX® STANDARD 100 certification. In this case, it is possible to achieve a high level of both quality and safety. It is preferable to use silk that has received a good evaluation in international textile product safety standard certification. It should be noted that the "OEKO-TEX® STANDARD 100" certification is a separate standard, and some items may be rated 6A but not have this certification.

[0046] In this embodiment, it is preferable to use 100% high-quality silk for the main body. The hair cap of this embodiment can be washed in a household washing machine. The reason it can be washed in a household washing machine is, for example, due to the selection of the material for the main body.

[0047] The main body of this embodiment is made of 100% satin silk, using high-grade 6A silk. The outer surface (glossy side) has the smoothness characteristic of satin fabric.

[0048] The main body is preferably made of silk formed with a satin weave. In this case, it will have a glossy appearance and will have a good effect on hair and skin. Fabrics formed with a satin weave include satin, etc. Whether or not a fabric is a satin weave can be determined, for example, by examining the degree of intersection of the warp and weft threads. Compared to plain weave, satin weave has a lower degree of intersection between the warp and weft threads, resulting in a glossy and smooth texture.

[0049] <Evaluation of wash fastness> The hair cap of this invention can be washed in a washing machine and exhibits good colorfastness when washed in a washing machine. Table 1 shows the results of the colorfastness evaluation of the hair cap of this embodiment. Each test item was evaluated on a scale from 1 to 5, with a score closer to 5 indicating less color fading and transfer.

[0050] [Table 1]

[0051] As shown in Table 1, the wash fastness, perspiration fastness, rubbing fastness, and water fastness are good. These results are thought to be due to the use of high-quality (6A rank) material in the main body. The lightfastness is a result specific to silk, and discoloration may occur if dried in direct sunlight. A lightfastness of grade 3 is acceptable.

[0052] Furthermore, the appearance and shape retention performance of the hair cap of this embodiment was evaluated after washing. The evaluation involved performing one prescribed wash cycle, simulating a household washing machine, followed by hanging to dry, and then evaluating the appearance and dimensional change rate. The appearance evaluation checked for any damage to the fabric, deformation, or fraying of the stitching. As a result, the appearance was fine, unchanged from before washing, and the results were satisfactory. In evaluating the dimensional change rate, we measured how much the size changed after washing. As a result, there was a 0.0% change in the width direction and a -2.4% change in the length direction. A slight shrinkage was observed in the length direction, but given the properties of silk, this is within an acceptable range and is considered acceptable.

[0053] When washing in a washing machine, it's best to turn the item inside out. For example, this protects the surface, which has a strong sheen characteristic of satin fabric. The relatively rough reverse side comes into contact with your hair, while the relatively smooth surface comes into contact with your face, etc. (when used as a pillowcase), making it easier to maintain the surface's sheen for a longer period of time.

[0054] <String part> The hair cap of this invention has a first string portion 3a provided at the first opening 6a and a second string portion 3b provided at the second opening 6b. In other words, the hair cap of this invention has two string portions. The string portions may simply be called strings or the like. Also, since it is envisioned that each string portion will be tied in a bow, for example, the string portions may be called ribbon portions or the like.

[0055] The cord can be made of flat cord (a cord with a flat cross-section), round cord (a cord with a round cross-section), etc. A flat cord is preferable for the cord portion, as this makes it less likely to leave marks when the cord is pulled and tied.

[0056] The cord portion is preferably a flat cord with some width. If the cord portion is a flat cord, the width of the cord portion can be selected as appropriate. Examples of cord portion widths include 1 cm to 5 cm, 1 cm to 3 cm, etc. The cord portion is preferably a flat cord with a width of 1 cm to 3 cm. This makes it less likely to leave marks when the cord is pulled and tied. It also improves ease of handling. Within the above range, it is possible to simultaneously ensure that the cord does not easily come off during use, is easy to tie, and does not leave marks. The inventor of this invention found the above range by testing the ease of tying, ease of untangling, etc., by changing the width of the cord portion.

[0057] In the hair cap of this invention, by appropriately designing the shape and arrangement of the string portion, it is possible to improve the elimination of foreign body sensation, the resistance to slipping off, and the reduction of marks left by wearing the cap. Furthermore, it is preferable to change the width of the insertion portion according to the width of the string portion. As shown in the example in Figure 4, the width of the string portion and the width of the insertion portion are the length (distance, size) of the main body portion 2 in the longitudinal direction.

[0058] The width of the insertion section should be appropriately selected according to the width of the cord. For example, the width of the insertion section should be 0.5 cm to 1.5 cm larger than the width of the cord. For example, the width of the insertion section should be 2 cm to 5 cm. If the width of the cord and the width of the insertion section are above the lower limit of the above range, it will be possible to prevent them from becoming too narrow and reduce the likelihood of marks being left from use. If the width of the cord and the width of the insertion section are below the upper limit of the above range, it will be easier to ensure that they are easy to attach.

[0059] Preferably, the first cord portion 3a and the second cord portion 3b each extend 8 cm to 15 cm from their respective exits. The exits refer to the exits of the corresponding insertion portions, and may also be called the ends of the insertion portions. Figures 2(B) and (C) illustrate examples of the exits of the insertion portions. This improves ease of handling and tying. If the extension length is too short, it may be difficult to tie, and if the extension length is too long, the string may come into contact with the face when worn on the head, reducing the overall comfort.

[0060] The main body 2 is preferably made of silk formed in a satin weave, and the first cord portion 3a and the second cord portion 3b are preferably made of polyester. This combination provides beneficial effects to the hair while also improving the durability of the string. Furthermore, because the string is made of polyester instead of silk, it has higher friction than silk, making it less likely to come undone when tied. In addition to the above, nylon, cotton, and other materials may also be used for the cord portion.

[0061] As shown in Figure 4, the part through which the string passes (which may also be called the storage section) is formed by folding and sewing the main body to create the insertion point. This eliminates the need to create gathers, which reduces the likelihood of leaving marks on the user and improves ease of manufacturing.

[0062] The straps could be made of lace, for example. Using lace would, for instance, reduce the weight. Other additions such as ruffles or embroidery could also be made.

[0063] <Other uses> Unlike conventional bag-shaped hair caps, the hair cap of this invention has an open shape at both ends. This allows it to be used effectively for purposes other than hair caps. From this perspective, the hair cap of this invention may also be referred to as a multi-purpose textile product, a multi-purpose textile structure, or the like.

[0064] For example, by putting a pillow through it, it can be used as a pillowcase. Figure 7 is a schematic plan view illustrating an example of its use as a pillowcase. When used as a pillowcase, for example, after threading the hair cap of this invention onto the pillow, tying the strings will prevent the hair cap from easily coming off the pillow.

[0065] When used as a pillowcase, the silk material of the main body provides beneficial effects on the hair. For example, it gives hair a smooth feel and a pleasant texture. The hair cap of this invention has an open shape at both ends of the main body, making it easy to attach to a pillow. In addition, tying the strings prevents it from falling off the pillow.

[0066] In addition, for example, by opening both ends of the main body and spreading it out, it can be used as a lap blanket. Furthermore, since this invention uses a string rather than a rubber material to fix the size of the opening, the open state of both ends of the main body can be maintained by untying the string. Therefore, it can be used as a lap blanket when the main body is spread out. If the main body is made of silk, for example, it is preferable for the main body to be in contact with the user's skin when spread out. Because it feels good against the skin when used, a good user experience can be obtained when using it as a lap blanket or shoulder wrap. Figure 8 is a schematic diagram illustrating an example of its use as a lap blanket. The illustration of the straps has been omitted.

[0067] This invention can be used for purposes other than a hair cap when not being used as one. For example, if the frequency of using a hair cap decreases during hot weather, it can be used for other purposes such as a pillowcase or lap blanket. In this way, the hair cap of this invention can be used throughout the year. Also, when not using a hair cap depending on the condition of your hair, it can be used for other purposes. This invention uses a main body that opens at both ends, with strings provided at each opening, and is attached using the strings. Therefore, it is possible to maintain the state of having both ends open or closed, and it can be used for purposes other than a hair cap. [Explanation of Symbols]
