Description

Mask {MASK}

The present invention relates to a mask mounted on a face of a person.

Japanese Patent Laid-Open No. 7-275384 discloses a mask covering a wearer's mouth and nose, particularly a three-dimensional mask. This three-dimensional mask is composed of a mask body, a left side ear hook part and a right side ear hook part. The mask body is configured to have a two-dimensional structure when the mask is folded and a three-dimensional structure when the mask is worn. As a result, a space around a mouth is formed between the mask body portion and the wearer's mouth, thereby making it possible to eliminate unpleasant feelings such as choking.

By the way, when designing and developing such a mask, what suits a wearer's face well (fitting) is important. In order to improve the fit, the wearer's facial features, the wearer's behavior pattern when handling the mask, and the like should be considered. For example, a wearer with a low nose and a high ball, or a wearer with a short vertical gap between the nose and the ear, if a general adult mask is used, the mask may be displaced from an appropriate wearing position or have sufficient space around the wearer's mouth. It may not be possible. In addition, simply reducing a general adult mask into a similar form is not sufficient as a mask used by a wearer such as a child or an adult having a small face.

The present invention was devised in view of the above, and an object of the present invention is to provide a mask that suits a wearer's face.

In order to achieve the said subject, the invention described in each claim is comprised.

One invention is a mask mounted on a wearer's face and includes a mask body portion, a left earring portion and a right earring portion covering the wearer's mouth and nose. The mask of this invention may be of the disposable type which assumed use once or several times, or may be of the type which can be used repeatedly by washing. In addition, the mask of the present invention can be suitably used by children, including infants, elementary school students, junior high school students, and adults with small faces, but can also be used by general adults by expanding in a similar form.

The mask body portion has a left sheet portion and a right sheet portion bonded to the edge portion. The mask body portion of the present invention is configured to be at least a three-dimensional shape when the mask is worn, and a space around the mouth is formed between the mask body portion and the wearer's mouth. Typically, the mask body is configured to be planar when the left sheet portion and the right sheet portion overlap with each other, and are planar when the mask is separated from the left sheet portion and the right sheet portion (when the mask is enlarged and opened).

The mask body portion is formed by partially joining one sheet portion (sheet member) or by joining all or part of a plurality of sheet portions (sheet member). The sheet portion forming the mask body portion is typically manufactured by sticking or entangled fibers with each other by mechanical treatment, chemical treatment, or thermal treatment, and typically a thermomelt fiber (thermoplastic fiber) It is comprised by the nonwoven fabric which can be welded (welded) in some.

The left earring part and the right earring part have a left earring hole and a right earring hole that are caught by the wearer's left and right ears, and extend from the left and right sides of the mask body part. The left earring portion and the right earring portion may be separate from the mask body portion or may be integral with the mask body portion.

In the present invention, at the time of folding the mask, an upper end portion of the left boundary line is orthogonal to the left boundary line between the mask body portion and the left earring portion (including approximately orthogonal) and connects the edge of the left boundary line and the left sheet portion. The length of the line passing through is shorter than the length of the line passing through the lower end of the left boundary line. Similarly, at the time of mask folding, the line passing through the upper end portion of the right boundary line is orthogonal to the right boundary line (including orthogonality) between the mask body portion and the right earring portion, and connects the right boundary line and the edge portion of the right sheet portion. It is comprised so that length may become shorter than the length of the line through the lower end part of a right boundary line. In other words, the width at the upper end side of the mask body is shorter than the width at the lower end side. In the mask of the present invention, when the mask body is viewed from the wearer side or the opposite side at the time of wearing the mask (when the mask is enlarged and opened), the mask body has a trapezoidal shape in which the upper end side is short and the lower end side is long. The boundary line and the right boundary line form a substantially "H" shape. The left boundary line between the mask body portion and the left earring portion and the right boundary line between the mask body portion and the right earring portion are preferably formed in a straight line. When the left boundary line and the right boundary line are formed in a curved shape, a line orthogonal to a line connecting the upper and lower ends of each of the curved left boundary line and the right boundary line is a line perpendicular to the left boundary line and the right boundary line. do.

In the mask of this invention, the width | variety in the upper end part of the boundary line (left boundary line and right boundary line) of a mask main body part is comprised so that it may become shorter than the horizontal width in a lower end part. Thereby, the upper end part side of a mask main body part becomes more easily in surface contact with a wearer's nose. Therefore, when a child with a low nose and a high ball or a person with a small face wears a mask, it can prevent that a mask main-body part twists from an appropriate wearing position.

According to another aspect of the invention, at the time of mask folding, the line having the longest length is perpendicular to the left boundary line and connects the left boundary line and the edge portion of the left sheet portion than the center portion between the upper end portion and the lower end portion of the left boundary line. The longest line runs downward from the center between the upper end and the lower end of the right boundary line among the lines connecting the lower boundary and orthogonal to the right boundary line and connecting the right boundary line and the edge portion of the right seat portion. That is, the top part (top part of a mouth lid part) of a mask main body part is arrange | positioned below the center part of the up-down direction of a left boundary line and a right boundary line.

This can prevent the mask from distorting from an appropriate wearing position when the mask is used by a child or a person with a small face. In addition, since the top part of the mask body part is disposed below the center part in the vertical direction of the left boundary line and the right boundary line, a child or face having a small difference in height between the tip of the nose and the tip of the mouth (short interval from the lips to the tip of the nose) is When a small person wears a mask, the space around the wearer's mouth can be sufficiently secured.

In still another aspect of the present invention, in the mask folding, the left earring hole is disposed below the line connecting the upper end of the left boundary and the upper end of the edge of the left sheet, and the right earring hole is the upper end of the right boundary. It is arrange | positioned below the line which connects the upper end part of the edge part of the right seat part. That is, the left earring hole and the right earring hole are disposed below the mask of a normal adult.

This can prevent the mask from distorting from an appropriate wearing position when the mask is used by a child or a person with a small face. In addition, when a child or the like having a short vertical gap between the nose and the ear (in detail, the vertical gap between the upper part of the nose root and the upper part of the ear root) is used, the mask can be easily set to an appropriate wearing position. . In addition, the length of the upper part and the length of the lower part of the left earring part with the left earring hole interposed therebetween, and the length of the upper part and the length of the lower part of the right earring part having the right earring hole interposed therebetween are approximately the same, or The length of the part is slightly longer than the length of the lower part. Thus, in order to fasten the left and right earrings to the left and right ear of the wearer, even if the left earrings and the right earrings are strongly stretched in the left and right directions, the upper and lower portions of the left and right earrings are approximately Increases equally. Therefore, since the force acts locally on the left earring part and the right earring part, the left earring part and the right earring part can be prevented from being in an extended state, thereby improving durability.

Another invention is a mask to be mounted on a wearer's face, which is formed by a left seat portion and a right seat portion joined at an edge portion, the mask body portion covering the wearer's mouth and nose and from the left and right sides of the mask body portion. It extends and includes a left earring portion and a right earring portion having earring holes for the wearer's left and right ears. The mask body portion is configured to be at least three-dimensional when the mask is worn, and a space around the mouth is formed between the mask body portion and the wearer's mouth. Typically, the mask body is configured to be planar when the left sheet portion and the right sheet portion overlap with each other, and are planar when the mask is separated from the left sheet portion and the right sheet portion (when the mask is enlarged and opened).

And in another invention, at the time of mask folding, the line which has the longest length among the lines which orthogonally cross the left boundary line between a mask main body part and a left earring part, and connects the left boundary line and the edge part of a left sheet part is the upper end part of a left boundary line. The longest line is a line extending downward from the center portion between the bottom and the bottom portion, and perpendicular to the right boundary line between the mask body portion and the right earring portion, and connecting the right boundary line and the edge of the right sheet portion. It runs below the center between the top and bottom of. That is, the top part (top part of a mouth lid part) of a mask main body part is arrange | positioned below the center part of the up-down direction of a left boundary line and a right boundary line.

This can prevent the mask from distorting from an appropriate wearing position when the mask is used by a child or a person with a small face. In addition, since the top of the mask body is disposed below the upper and lower centers of the left boundary line and the right boundary line, a mask of a child or a person having a small difference in the height between the tip of the nose and the tip of the mouth (short interval between the lips and the tip of the nose) is used. When wearing, it is possible to secure a sufficient space around the wearer's mouth.

In another aspect of the present invention, at the time of mask folding, the left earring hole is disposed below the line connecting the upper end of the left boundary line and the upper end of the edge portion of the left seat portion, and the right earring hole is connected with the upper end of the right boundary line. It is arrange | positioned below the line which connects the upper end part of the edge part of a right seat part. That is, the left earring hole and the right earring hole are disposed below the mask of a normal adult.

This can prevent the mask from distorting from an appropriate wearing position when the mask is used by a child or a person with a small face. In addition, the mask can be easily set to an appropriate wearing position when the child has a short vertical gap between the nose and the ear (more specifically, the vertical gap between the upper part of the nose root and the upper part of the ear root). have. In addition, the length of the upper portion and the length of the lower portion (the length of the upper portion and the length of the lower portion with the right earring hole interposed between the right earring portion) between the left earring portion are approximately the same, Or the length of the upper portion is slightly longer than the length of the lower portion. As a result, even when the left earring portion and the right earring portion are strongly stretched in the left and right directions, the upper and lower portions of the left earring portion and the right earring portion are substantially increased in the same manner. Therefore, since the force acts locally on the left earring part and the right earring part, the left earring part and the right earring part can be prevented from being in an extended state, thereby improving durability.

Another invention is a mask to be mounted on a wearer's face, which is formed by a left seat portion and a right seat portion joined at an edge portion, and includes a mask body portion covering the wearer's mouth and nose, and left and right sides of the mask body portion. And a left earring portion and a right earring portion having a left earring hole and a right earring hole that extends from the wearer's left and right ears. The mask body portion is configured to be at least three-dimensional when the mask is worn, and a space around the mouth is formed between the mask body portion and the wearer's mouth. Typically, the mask body is configured to be planar when the left sheet portion and the right sheet portion overlap with each other, and become planar when the mask is separated from the left sheet portion and the right sheet portion (when the mask is enlarged and opened).

In the present invention, at the time of folding the mask, the left earring hole is disposed below the line connecting the upper end portion of the left boundary line between the mask body portion and the left earring portion and the edge portion of the edge portion of the left sheet portion, and the right earring hole is It is arrange | positioned below the line which connects the upper end part of the right boundary line between the mask main body part, and the right earring part, and the upper end part of the edge part of a right sheet part. That is, the left earring hole and the right earring hole are disposed below the mask of a normal adult.

Thereby, when a child or a person with a small face uses a mask, it can prevent that a mask is twisted from an appropriate wearing position. In addition, when a child or the like having a short vertical gap between the nose and the ear (in detail, the vertical gap between the upper end of the nose root and the upper end of the ear root) is used, the mask can be easily set at an appropriate wearing position. Can be. Further, the length of the upper part and the length of the lower part (the length of the upper part and the length of the lower part with the right earring hole interposed between the right earring part) between the left earring holes of the left earring part are approximately the same, or The length of the upper part is slightly longer than the length of the lower part. Thereby, even if the left earring part and the right earring part are strongly stretched in the left-right direction, the upper part and the lower part of the left earring part and the right earring part extend substantially equally. Therefore, since the force acts locally on the left earring part and the right earring part, it is possible to prevent the left earring part and the right earring part from being in an extended state, thereby improving durability.

In a further different form of the invention, at least one of the mask body portion, the left earring portion, the right earring portion, the left boundary portion between the mask body portion and the left earring portion, and the right boundary portion between the mask body portion and the right earring portion, It includes a display that can determine the vertical direction. Thereby, the wearer can easily determine the up-down direction of the mask by a display part. The display portion is typically configured by forming an emboss provided in the left earring portion and the right earring portion so as to display letters, symbols, shapes, patterns, or the like, or printing the letters, symbols, shapes, patterns, etc. do.

Another different invention further comprises a mask body mounted on the wearer's face, the mask body portion, the left earring portion and the right earring portion. And this invention is further provided with the seal element which can be adhere | attached on the outer surface of a mask main-body part. Alternatively, the present invention further includes a seal member adhered to an outer surface of the mask body portion. As the seal member, a seal member having a display that a child is interested in, such as a character, is suitably used. As a result, the interest in the wearer's mask can be enhanced by the seal member.

As described above, the present invention can provide a mask that suits the wearer's face well.

EMBODIMENT OF THE INVENTION Below, the structure of the mask 1 of one Embodiment of this invention is demonstrated, referring drawings. In addition, the mask 1 of this embodiment is a disposable mask which assumed use | use once or several times. The mask 1 may be a mask having a barrier function against pollen or a cold virus or a function improving an environment in a space around a mouth. It can use as a mask which has a. In addition, although the mask 1 is typically used suitably by an infant, an elementary school student, a junior high school child, an adult with a small face, etc., the mask 1 can be used also by a general adult etc. by making the mask 1 large. .

In FIG. 1 and FIG. 2, the whole structure of the mask 1 of this embodiment is shown. 1, the figure seen from the side surface in the state which folded the mask 1 (when mask folding) is shown. In addition, in FIG. 2, the figure seen from the wearer side in the mask 1 opened state (when mask expansion is opened) is shown. As shown in FIG. 1 and FIG. 2, the mask 1 of this embodiment is constituted by a mask body 2 and an ear hook part 3.

[Mask main body part 2]

The mask body 2 is a member covering at least the mouth of the wearer, suitably the mouth and the nose, and is formed in a cup shape. The mask body part 2 is also called a "cup-shape part" or a "mouth cover part."

In the present embodiment, the mask body portion 2 includes a left seat portion 2a covering the left side of a face of the wearer and a right seat portion covering the right side of a face of the wearer ( It is comprised by 2b). The left sheet portion 2a and the right sheet portion 2b are joined by thermal welding at the point of the edge portion 2c. Thereby, the mask main body part 2 is divided into left and right on the edge part 2c as a boundary. The shapes of the left sheet portion 2a and the right sheet portion 2b (particularly, the shape of the edge portion 2c) are joined at the point of the edge portion 2c, and the left sheet portion 2a and the right sheet portion are When (2b) falls (at the time of enlarged opening), it is designed so that a hollow may be formed in the wearer side of the mask main body 2. In the present embodiment, the left sheet portion 2a and the right sheet portion 2b have the same shape. In addition, the edge portion 2c extends in a curved shape in the vertical direction of the wearer.

Thereby, the mask main body 2 is shown in FIG. 1 at the time of mask folding ("mask storage" or "non-mask usage") where the left sheet portion 2a and the right sheet portion 2b overlap. It is planar as it is. On the other hand, at the time of mask enlargement opening ("mask wearing") in which the left sheet portion 2a and the right sheet portion 2b are separated, the mask body portion 2 becomes a three-dimensional shape as shown in FIG. In addition, the mask main body 2 should just be a three-dimensional shape at least at the time of mask wearing. For example, it may be a three-dimensional shape when the mask is worn and when the mask is not worn.

The mask 1 provided with the mask main-body part 2 which becomes a three-dimensional shape at least at the time of mask wearing is called "stereoscopic mask" or "three-dimensional mask."

In the present embodiment, the mask body portion 2, that is, the left sheet portion 2a and the right sheet portion 2b are formed of nonwoven fabrics made of thermoplastic synthetic fibers. As the thermoplastic fiber, polyethylene, polypropylene, polyethylene terephthalate or the like is used, and an air through method, a spun bond method, and a thermal bond method are used. thermal bond method, spun lace method, point bond method, melt blow method, stitch bond method, chemical bond method The density of fibers produced by the needle punch method or the like can be suitably used in the range of 30 [g / m ² ] to 150 [g / m ² ]. As a nonwoven fabric, it is preferable to use the thing which has performance for capturing pollen and virus droplets, has breathability, and is soft and confortable. In addition, it is preferable to use one having a lower elasticity than the earring part 3 so that the three-dimensional structure is easily maintained when the mask is worn.

[Earrings (3)]

The earring part 3 has the left earring part 3a and the right earring part 3b provided in the left and right both sides of the mask main-body part 2. In the present embodiment, the left earring portion 3a extends from an end (opposite to the edge portion 2c) of the left sheet portion 2a of the mask body portion 2, and the right earring portion 3b is the mask body. It extends from the edge part of the right side sheet part 2b of the part 2. In addition, the left earring portion 3a is formed in a ring-shape having a left earring hole (opening) 5a that is caught by the wearer's left ear, and the right earring portion 3b is a right earring hole (which is caught by the wearer's right ear) It is formed in a ring shape having an opening 5b. The left earring hole 5a and the right earring hole 5b extend in the direction crossing the vertical direction of the mask 1 (up and down direction in FIG. 1).

At the time of wearing a mask, the left earring hole 5a of the left earring part 3a is caught by the wearer's left ear while the wearer's mouth and nose are covered by the mask body part 2, and the right earring part 3b The right earring hole 5b is caught in the wearer's right ear.

In the present embodiment, the left earring portion 3a and the right earring portion 3b are formed separately from the mask body portion 2, and the left side boundary region 4A and the right side boundary, respectively. In region 4B, the mask body portion 2 partially overlaps and is joined. Although described later in detail, as a method of joining the left earring portion 3a, the right earring portion 3b, and the mask body portion 2, an emboss roller having an uneven shape is used. A so-called "embossing process" can be used to bond.

In this embodiment, the left earring part 3a and the right earring part 3b are formed of the nonwoven fabric which consists of thermoplastic synthetic fibers similarly to the mask main-body part 2. In addition, as this nonwoven fabric, when wearing a mask, it is preferable to use the thing which has elasticity which a wearer does not feel an ear pain. For example, the nonwoven fabric which has higher elasticity than the mask main-body part 2 is used. Specifically, the left earring portion 3a and the right earring portion 3b are expanded layers made of expandable non-elastically extensible fibers (for example, nonwoven fabric in which propylene continuous fibers are welded to each other). ) And an elastic layer made of elastically stretchable elastic stretchable fibers (for example, a nonwoven fabric made of an elastomeric yarn made of elastomer or urethane, etc. of thermoplastic synthetic fibers) is laminated. do. In addition, although it mentions later in detail, several holes (openings) 6 are formed in the left earring part 3a and the right earring part 3b. The elasticity of the left earring part 3a and the right earring part 3b is improved by these some holes 6.

By the way, when designing and developing the mask 1, what suits a wearer's face well (fitting property) is important. In order to improve this fit, the wearer's characteristics such as the size and shape of the face and the wearer's action pattern such as how to handle the mask should be sufficiently considered. For example, a child has a lower nose and a higher cheek than a normal adult, and also has a shorter vertical gap between the nose and the ear. When such a child uses a general adult mask, there is a fear that the mask body part may be displaced from an appropriate position or may not be able to secure a sufficient space around the mouth. Moreover, simply forming a general adult mask small does not necessarily reflect the characteristics of the face of a small person with a child or a face.

Therefore, the present inventors analyze the characteristics of the child's face and the child's behavior pattern, and the mask main body 2 and the earring part 3 (left earring part 3a, right earring part) constituting the mask 1 are analyzed. (3b)], a review point was extracted to correspond to the feature of the child's face or the child's behavior pattern. At that time, the following six review points were extracted.

[Shape of face]

(1) Child has lower nose than general adult, and ball is high (soars). In addition, they often have round noses than adults.

(2) The child has a shorter interval from the lips to the tip of the nose than an adult.

(3) The child has a shorter vertical gap between the nose and the ear (more specifically, the vertical gap between the upper end of the root of nose and the upper end of the ear root) than an adult.

[Behavior pattern]

(4) The child is often chattered away, so the mask is likely to be displaced from the proper position (not in the proper place).

(5) Since the child tends to pull the earring part strongly when the earring hole of the earring part is put on the ear, the earring part tends to increase.

(6) Because child gets tired well, interest in mask does not continue for a long time.

Moreover, the present inventors examined the mask especially suitable for a child based on these review points. And the mask which has at least 1 structure among the 1st-6th structures shown below was developed.

(First structure)

The first structure of the mask 1 will be described with reference to FIGS. 3 and 4. 3, the figure seen from the side surface in the state which folded the mask 1 (when mask folding) is shown. 4 shows a view of the mask 1 viewed from the wearer side in a state in which the mask 1 is opened (when the mask is enlarged and opened).

In addition, in this embodiment, since the mask main body part 2 (left seat part 2a) and the left earring part 3a overlap and join by the left boundary part 4A, the mask main body part 2 (left side) is joined. There are two straight boundary lines between the sheet portion 2a and the left earring portion 3a. Similarly, since the mask main body 2 (right sheet 2b) and the right earring 3b are superimposed at the right boundary 4B, the mask main body 2 (right sheet 2b) is joined. ] And a right boundary line of two points exists between] and the right earring part 3b. Hereinafter, the boundary line of the left earring hole 5a side is used as the left boundary line 4a among the boundary lines of the two points of the mask main-body part 2 and the left earring part 3a, and also the mask main-body part 2 The case where the boundary line of the right earring hole 5b side is used as the right boundary line 4b among the boundary lines of the two points between and the right earring part 3b. Moreover, the boundary line of the edge part 2c side of the left sheet part 2a (right seat part 2b) among the boundary lines of two points can also be used as left boundary line 4a (right boundary line 4b).

The first structure was developed based on the review points (1) and (4), and the dimensions of the width in the left and right directions of the mask body part 2 are reviewed. In the first structure, the width on the upper end side (a in FIG. 3) is set shorter than the width on the lower end side (b in FIG. 3).

Specifically, at the time of folding the mask shown in FIG. 3, the boundary line (left boundary line) 4a and the left sheet between the mask body portion 2 (left seat portion 2a) and the left earring portion 3a are provided. Between the edge part 2c of the part 2a, the line (1st line) L1 orthogonal to the left boundary line 4a and through the upper end X1 of the left boundary line 4a, and the left boundary line 4a Draw a line L2 (called the "second line") through X2 of the lower end. The length between the upper end portion X1 of the left boundary line 4a and the point Y1 at which the first line L1 intersects the edge portion 2c of the left sheet portion 2a is defined as the length a of the first line L1. The length between the lower end portion X2 of the left boundary line 4a and the point Y2 at which the second line L2 intersects the edge portion 2c of the left sheet portion 2a is defined as the length b of the second line L2. In the first structure, the length a of the first line L1 is set to be shorter than the length b of the second line L2 (a <b).

Similarly, between the boundary line (right boundary line) 4b between the mask main body part 2 (right seat part 2b) and the right earring part 3b, and the edge part 2c of the right seat part 2b, the right side The line (first line) L1 passing perpendicular to the boundary line 4b and passing through the upper end portion X1 of the right boundary line 4b and the line (second line) L2 passing through the lower end portion X2 of the right boundary line 4b are drawn. And the length (length between X1 and Y1) a of 1st line L1 is set so that it may become shorter than the length (length between X2 and Y2) b of 2nd line L2 (a <b).

In the first structure, in the mask enlargement opening shown in FIG. 4, the length (lateral width on the upper end side) between the left and right upper end portions X1 is twice the length a of the first line L1 (2 × a) and Roughly equal. In addition, the length (lateral width on the lower end side) between the left and right lower end portions X2 is approximately equal to twice (2 × b) the length b of the second line L2. That is, in the state where the mask 1 is enlarged and opened in a three-dimensional shape, when viewed from the wearer side or the opposite side, the mask main body 2 has a trapezoidal shape in which the upper end X1 side is a short side and the lower end X2 side is a long side, or The left boundary line 4a and the right boundary line 4b form a "H" shape.

As described above, in the first structure, the width at the upper end X1 of the mask body 2 is shorter than the width at the lower end X2. For this reason, when the eye etc. with a low nose and a high ball use it, the upper end part X1 side of the mask main-body part 2 will be in surface contact with the wearer's nose easily. Therefore, it is possible to prevent the mask from twisting from an appropriate wearing position.

More specifically, at the time of wearing the mask, an edge portion of the uppermost portion of the mask body portion 2 is disposed on the ridge line of nose of the wearer's nose, and the left seat portion 2a and the right seat portion are disposed. 2b is arrange | positioned along the inclination part of the left side of the nose, and the inclination part of the right side, respectively. At this time, since the width of the upper end of the mask main body 2 is shorter than the width of the lower end, the left seat 2a and the right seat 2b are arranged in a state that satisfactorily fits the nose of the wearer.

In addition, since the width of the upper end of the mask main body 2 is shorter than the width of the lower end, when the left earring 3a and the right earring 3b are hooked to the ear, the left earring 3a and the right earring 3 ( The force that 3b) tensions the mask main-body part 2 has an upper end part larger than a lower end part. That is, the force which presses the mask main body 2 to the wearer's face is large at the upper end of the mask main body 2, and small at the lower end. In addition, since the width of the lower end of the mask main body 2 is longer than that of the upper end, the lower end of the mask main body 2 covers a wide range of the jaws of the wearer, and the lower end of the mask main body 2 The force applied to the wearer's chin is easily distributed. Thereby, the movement which follows the movement of a wearer's chin of the mask main-body part 2 is suppressed. Therefore, even if the wearer speaks in a state where the mask is worn, the mask body 2 is hardly twisted from an appropriate wearing position.

The left boundary line 4a (right boundary line 4b) between the mask body portion 2 and the left earring portion 3a (right earring portion 3b) is preferably formed in a straight line, but may be formed in a curved line. have. When the left boundary line 4a (right boundary line 4b) is formed in a curved shape, a straight line connecting the upper end X1 and the lower end X2 of the left boundary line 4a (right boundary line 4b) is a line L1 and a line L2. It is used as a left boundary line (right boundary line) for drawing.

(Second structure)

The second structure of the mask 1 will be described with reference to FIGS. 5 and 6. 5, the figure seen from the side surface in the state which folded the mask 1 (when mask folding) is shown. 6, the figure seen from the wearer side in the mask 1 opened state (when mask expansion is opened) is shown.

The second structure was developed on the basis of the review point 2, and the position of the top point of the mask body part 2 is reviewed. In the 2nd structure, the position of the top part (point Y4 in FIG. 5) (top part of the mouth lid part) of the mask main-body part 2 is arrange | positioned below the center part of the mask 1 in the up-down direction.

Specifically, at the time of folding the mask shown in FIG. 5, the boundary line (left boundary line) 4a and the left sheet between the mask body portion 2 (left seat portion 2a) and the left earring portion 3a are provided. A line orthogonal to the left boundary line 4a is drawn between the edge portions 2c of the portion 2a. The point X4 is the point at which the longest line (fourth line) L4 between the left boundary line 4a and the edge portion 2c of the left sheet portion 2a intersects the left boundary line 4a. In the second structure, the fourth line (the longest line) L4 through the point X4 of the left boundary line 4a passes through the center X3 between the upper end X1 and the lower end X2 of the left boundary line 4a (third line). It is set to be placed below L3. That is, the point X4 through which the 4th longest line L4 passes through is set so that it may be arrange | positioned below central part X3.

Similarly, between the boundary line (right boundary line) 4b between the mask main body part 2 (right seat part 2b) and the right earring part 3b, and the edge part 2c of the right seat part 2b, the right side A line perpendicular to the boundary line 4b is drawn. The point X4 is the point at which the longest line (fourth line) L4 between the right boundary line 4b and the edge portion 2c of the right seat portion 2b intersects the right boundary line 4b. And the 4th line (longest line) L4 through the point X4 of the right boundary line 4b is lower than the line (third line) L3 through the upper end X1 of the right boundary line 4b, and the center part X3 of the lower end X2. It is set to be placed in.

In the second structure, in the mask enlargement opening shown in FIG. 6, the length (the width of the top portion) between the left and right points X4 is approximately equal to twice (2 × c) the length c of the fourth line L4. Lose.

Thus, in the 2nd structure, the top part Y4 (position of the line L4 with the longest width | variety) of the mask main-body part 2 is arrange | positioned below the center part X3 of the up-down direction of the mask 1. Therefore, the space around the mouth of the wearer can be increased when used by a child or the like with a short interval from the lips to the tip of the nose.

(Third structure)

The third structure of the mask 1 will be described with reference to FIGS. 7 and 8. In addition, in FIG. 7, the figure seen from the side surface is shown in the state which folded the mask 1 (when mask folding). 8, the figure seen from the wearer side in the mask 1 opened state (when mask expansion is opened) is shown.

The third structure was developed based on the review points (3), (4) and (5), and the arrangement positions of the left earring hole 5a and the right earring hole 5b are reviewed. In the second structure, the left earring hole 5a and the right earring hole 5b are disposed at a position lower than that of a normal adult mask.

Specifically, the upper end portion Y5 of the edge portion 2c of the mask body portion 2 (left seat portion 2a) at the time of folding the mask shown in FIG. 7 and at the time of expanding and expanding the mask shown in FIG. 8. And the line (fifth line) L5 connecting the upper end X1 of the boundary line (left boundary line) 4a between the mask body portion 2 (left seat portion 2a) and the left earring portion 3a. In the second structure, the left earring hole 5a of the left earring part 3a is disposed below the fifth line L5.

Similarly, between the upper end portion Y5 of the edge portion 2c of the mask body portion 2 (right sheet portion 2b), and between the mask body portion 2 (right sheet portion 2b) and the right earring portion 3b. A line (fifth line) L5 connecting the upper end portion X1 of the boundary line (right boundary line) 4b is drawn. And the right earring hole 5b of the right earring part 3b is arrange | positioned below 5th line L5.

Thus, in the 3rd structure, the left earring hole 5a of the left earring part 3a is the upper end part Y5 of the edge part 2c of the main body part 2 (left seat part 2a), and a mask main body part (2) It is disposed below the line L5 connecting the upper end X1 of the left boundary line 4a between the [left seat portion 2a] and the left earring portion 3a and the right earring hole of the right earring portion 3b. 5b is the upper end Y5 of the edge 2c of the main body 2 (right seat 2b), the mask main body 2 (right seat 2b) and the right earring 3b. It is arrange | positioned below the line L5 connecting the upper end part X1 of the right boundary line 4b between them. Thereby, when the child etc. with a short vertical space | interval (in detail, the vertical space | interval between the upper part of a nose root and the upper part of an ear root) between a nose and an ear are used, the mask main body part 2 may be appropriately adjusted. It can be placed in a wearing position.

When the third structure is used, the length of the upper portion of the left earring portion 3a than the left earring hole 5a and the length of the lower portion than the left earring hole 5a are approximately the same, or the left earring hole ( The length of the upper portion than 5a) is slightly longer than the length of the lower portion than the left earring hole 5a. Similarly, the length of the upper portion of the right earring portion 3b than the right earring hole 5b and the length of the lower portion than the right earring portion 5b are approximately equal to, or the length of the upper portion of the right earring hole 5b. Is slightly longer than the length of the lower portion than the right earring hole 5b. Thereby, even if the left earring part 3a (right earring part 3b) is stretched to some extent in the lateral direction, the upper part of the left earring hole 5a and the lower part of the left earring hole 5a (right earring) Since the upper portion than the hole 5b and the lower portion than the right earring hole 5b are substantially similarly extended, the left earring portion 3a (right earring portion 3b) is prevented from locally stretching. Therefore, when the child or the like is used, the mounting performance can be prevented from being reduced in a short time (durability is improved).

(Fourth structure)

The fourth structure of the mask 1 will be described with reference to FIG. 9. 9, the figure which looked at the earring part 3 (left earring part 3a and right earring part 3b) in the state which folded the mask 1 (when mask folding) is shown from the side. .

The fourth structure was developed on the basis of the review point 5, and the material and configuration of the earring section 3 (left earring section 3a and right earring section 3b) are reviewed.

Specifically, the left earring portion 3a and the right earring portion 3b are made of crimp fibers having a fiber length of 44 mm or more. A plurality of holes (openings) 6 are formed in the left earring portion 3a and the right earring portion 3b. The hole 6 is formed in the elliptic shape which has two axes (long axis 6a and short axis 6b) from which a cross section differs in length. In addition, the cross section of the hole 6 is not limited to an elliptical shape, but can be formed in various shapes, such as a rhombic shape, a polygonal shape, and a circular shape.

This hole 6 typically sprays a water jet (high-pressure water) onto the front of the web when producing spun-laced non-woven fabrics. After tangling fibers of a web by jetting water jet (high-pressure water) on the whole surface of a web, further by jetting water jet (high pressure water) on the surface of a web. By forming the hole 6 using a waterjet, the density of fibers at the edge of hole 6 becomes higher than the fiber density at other points. That is, the elastic force at the edge of hole 6 (also referred to as a "recovery force, spring force") increases. For this reason, the left earring part 3a and the right earring part 3b extended for wearing the mask 1 can be easily returned to an original state.

In addition, the fiber density of at least a part of the edge portion of the hole 6 may be higher than the fiber density at other points. For example, the structure where the fiber density of a part of the edge of the hole 6 is higher than the fiber density at another point of the edge part of the hole 6, or the fiber density of a part of the edge part of the hole 6 is this hole ( The structure higher than the fiber density of the point other than the edge part of 6) may be sufficient. In this case, it is preferable to configure so that the fiber density of the point which intersects the short axis 6b of the hole 6, and its peripheral point becomes high.

The process of manufacturing a spunlace nonwoven fabric has the following processes more specifically.

Card process; Using the open tow, make webs having uniform density of fibers along the width direction using tows opened from its original tows.

Water jet process; Tangle fibers of webs by jetting high pressure water on the whole surface of webs such that the strength of sheet is increased.

Hole-make water jet process; Holes are formed in the sheet by passing a woven sheet over a structure (net punched plate) having projections through which water passes, and then spraying high pressure water flow from the projections. (When carrying a sheet having fibers tangled on the structure having projections through which water flows, make holes on a sheet by jetting high pressure water from projections). Alternatively, instead of forming a hole in the sheet by spraying high pressure water flow, a step of forming a hole in the sheet by jetting high pressure steam jet may be used.

Dry process; Remove any moisture contained in the sheet.

Shrink process; In the case where the crimped fiber is formed of polypropylene / modified polypropylene, near 140 ° C., the modified polypropylene starts to shrink, but the polypropylene does not shrink. This results in a coil like (becomes like a coil). At this time, shrinkage occurs in the conveyance direction and the width direction of the sheet.

By the card process and the waterjet process, non-woven fabric bodies are made of fibers of which are oriented to the direction parallel to the transfer direction. Further, a hole is formed in the nonwoven gas by the injection of a fluid jet (high pressure water flow or steam fractionation) into the nonwoven gas by the open water jet process. That is, a hole is formed in the nonwoven fabric by the fibers constituting the nonwoven fabric being moved aside around a fluid jet. At this time, the injection position of the injection fluid (high pressure water flow or steam jet) is fixed, but since the nonwoven fabric is moving, a hole having an elliptical cross section is formed. Thereby, the fiber density of a hole edge part becomes high. Further, by the shrinkage process, the fibers at the point where the fiber density is high (the edge of the hole) are shrunk. Therefore, the elastic force (spring force) of the edge part of a hole becomes high.

In the fourth structure, when the left earring part 3a and the right earring part 3b are tensioned in order to fasten the left earring part 3a and the right earring part 3b to the left ear and the right ear, the right ear of FIG. As shown, the holes 6 formed in the left earring part 3a and the right earring part 3b change from the state of the dashed line to the state of the solid line. Thereby, the left earring part 3a and the right earring part 3b easily stretch in the tensioned direction (left-right direction in FIG. 9). When the left earring part 3a and the right earring part 3b are hooked to the left ear and the right ear by the structure in which the left earring part 3a and the right earring part 3b are extended by the deformation | transformation of the hole 6, The force on the wearer's ear is reduced. That is, the wearer can prevent the ear from feeling pain.

In addition, fibers gather at the edge of the hole 6, and the fiber density at the edge of the hole 6 is higher than the fiber density at other points. Thereby, the elastic force (recovery force or spring force) of the left earring part 3a and the right earring part 3b becomes high. Therefore, even if the mask 1 is used repeatedly, the left earring portion 3a and the right earring portion 3b can be prevented from being stretched and can be used for a long time (durability is improved (durability). is increased)].

In addition, at least a part (preferably all) of the hole 6 is, as shown in FIG. 9, when the mask is folded, the major axis 6a has the mask body part 2 and the earring part 3. It is preferable that it is formed so that it may become parallel to the boundary line 4 between. For example, the hole 6 of the left earring portion 3a is formed such that the major axis 6a is parallel to the boundary line 4a between the mask body portion 2 and the left earring portion 3a, and the right earring portion 3b Hole 6 is formed such that the major axis 6a is parallel to the boundary line 4b between the mask body portion 2 and the right earring portion 3b. In this case, the hole 6 may be formed so that the long axis 6a may be substantially parallel with the boundary line 4. By such a configuration, the earring part 3 (left earring part 3a and right earring part 3b) can be more easily stretched when the tensile force is applied. In addition, when the tensile force dissipates, it becomes possible to more easily return to the original state (return).

In addition, in embodiment shown in FIG. 9, the some hole 6 in which the cross section is formed in elliptical shape is arrange | positioned regularly. However, the cross-sectional shape of the hole 6 and the arrangement position are not limited to this. For example, a configuration in which the plurality of holes 6 are irregularly arranged, a configuration in which a plurality of holes 6 having different cross-sectional shapes are arranged regularly or irregularly, and the like can be adopted.

Here, a performance evaluation (comfortable tensile strength at the time of wearing) of comfort and durability of the mask having the left earring part 3a and the right earring part 3b of the present embodiment; Elongation recovery rate (recovering property from extension)]. Below, this performance evaluation procedure and result are demonstrated. In addition, JIS L-1096 method was used for the performance evaluation demonstrated below.

(Making of sample)

Three samples of 210 [mm] in length, 297 [mm] in width and 100.0 [g / m ² ] in unit weight were made using the same materials as the left earring part 3a and the right earring part 3b having the above-described configuration. It was. In addition, three samples each having a width of 50 [mm] and a length of 297 [mm] were taken from each sample, respectively.

(Measurement and Evaluation of Tensile Strength)

In the measurement of tensile strength, the sample of width 50 [mm] and length 297 [mm] was evaluated by a known constant speed elastic-type tension testing machine. In the measurement, the distance between positions to be catched was set to 200 [mm] and the tensile velocity was set to 200 [mm / min]. And the intensity | strength at the time of extending | stretching 50% of each sample and the intensity | strength when extending | stretching 90% was measured, and the average value of each sample was computed. In this case, the strength at 50% elongation was defined as 50% stress [N], and the strength at 90% elongation was defined as 90% stress [N]. And 50% stress is 1 [N] or less, 90% stress is 1 [N] or less, satisfying the desired comfort standard, that is, the earring part 3 (left earring part 3a and right earring part ( 3b)] was stretched to the ear (left ear and right ear) and had elasticity that did not cause pain in the ear.

(Measurement and evaluation of kidney recovery rate)

In the measurement of elongation recovery rate, the said sample of width 50 [mm] and length 297 [mm] was evaluated by the well-known constant velocity stretching type tester. In the measurement, the gripping interval of the sample was set to 200 [mm] and the tensile velocity to 200 [mm / min]. And a recovery ratio when returning to the home position at the same speed after 50% elongation, and a recovery degree when returning to the home position at the same speed after 90% elongation ( Ratio) was measured, and the average value of each sample was calculated. In this case, the degree of return after 50% elongation was determined as 50% elongation recovery rate [%], and the degree of return after 90% elongation was defined as 90% elongation recovery rate [%]. And 50% elongation recovery rate is 70 [%] or more, and 90% elongation recovery rate is 60 [%] or more, satisfying the desired durability standard, namely, earring part 3 (left earring part 3a) and The right earring part 3b] was evaluated to be difficult to be stretched.

As a result of evaluation, in order to satisfy a desired comfort standard and durability standard, the fiber length of the elastic fiber which comprises the earring part 3 (left earring part 3a and right earring part 3b) is 44 [mm] or more. It was confirmed that it is effective to set the size before shrinkage of the hole 6 to 10 mesh to 50 mesh. When the fiber length of the stretchable fiber is less than 44 [mm], even if the size before shrinkage of the hole 6 is increased, the stress applied to the ear exceeds the reference value. In addition, when the size before shrinkage of the hole 6 is made larger than 50 mesh, the elongation recovery rate is significantly smaller than the reference value. When the size before shrinkage of the hole 6 is made smaller than 10 mesh, the hole 6 is not formed, and the stress applied to the ear greatly exceeds the reference value.

(Fifth structure)

The fifth structure of the mask 1 will be described with reference to FIGS. 10 to 13. In addition, in FIG. 10, the figure seen from the side surface in the state which folded the mask 1 (when mask folding) is shown. 11 is a cross-sectional view taken along the line A-A of FIG. 10. 12 and 13 show an embodiment of a second emboss-formed portion 4c in FIG. 10.

The fifth structure is developed on the basis of the review point 6 described above, and the boundary 4 between the mask main body 2 and the earring part 3 (left earring part 3a and right earring part 3b) is provided. ) The embossed structure of (left boundary 4A and right boundary 4B) is reviewed.

Specifically, as shown in Fig. 10, on the left boundary 4A (right boundary 4B) between the mask main body 2 and the left earring 3a (right earring 3b), A plurality of first embossed portions 4c for joining the mask body portion 2 and the left earring portion 3a are formed over the entire left boundary portion 4A (right boundary portion 4B), A plurality of second embossed portions 4d having a shape different from that of the one embossed portion 4c is formed.

As shown in FIG. 11, the 1st embossing part 4c and the 2nd embossing part 4d are recessed by the emboss roller which has a non-even shape. It is a part machined into a concave.

The first embossed portion 4c has a function of increasing the bonding strength between the mask body portion 2 and the left earring portion 3a (right earring portion 3b).

Further, the second embossed portion 4d determines the vertical direction of the mask 1 in addition to the joining function of the mask main body 2 and the left earring portion 3a (right earring portion 3b). It has the function of the display part to display it possibly. The display form by the 2nd embossing part 4d can be variously selected. For example, the 1st display form which displays the information regarding the up-down direction of the mask 1 can be used by the single 2nd embossing part 4d. Moreover, the 2nd display form which displays the information about the up-down direction of the mask 1 can also be used by combining several 2nd embossing part 4d. As information displayed by the 2nd embossing part 4d, the character, a symbol, a pattern, a pattern, etc. which can distinguish the information about the up-down direction of the mask 1 can be used suitably.

As a 1st display form, for example, as shown in FIG. 12, the display form which displays a "up arrow" in each of 2nd embossing part 4d can be used. This makes it possible to determine that the end of the arrow is above the mask 1.

In addition, as a 2nd display form, as shown, for example in FIG. 13, "A"-"E" which show a procedure to the 2nd embossing part 4d from the upper side to the lower side of the mask 1 in order. It is possible to use a display form that displays. In this case, "A" representing the first is displayed on the second embossed portion 4d disposed above the mask 1, and "E" representing the end is disposed below the mask 1. The 2nd embossing part 4d is displayed. Thereby, the 2nd embossing part 4d side in which "A" is displayed is the upper side of the mask 1, and the 2nd embossing part 4d side in which "E" is displayed is the side of the mask. The lower side can be determined.

By using the fifth structure, the wearer can easily determine the vertical direction of the mask 1. Moreover, since the embossing part for joining also serves as a display part, it is not necessary to provide a new display part and manufacturing cost can be reduced. In addition, display information, for example, a character or the like, which is easy to attract the child may be displayed on the second embossing part 4d. This can increase interest in the mask, especially when the wearer is a child.

Further, at the boundary portion 4 (left boundary portion 4A, right boundary portion 4B) between the mask body portion 2 and the earring portion 3 (left earring portion 3a, right earring portion 3b). Although the information regarding the up-down direction of the mask 1 was displayed by the embossing structure, in addition to the boundary part 4 or in addition to the boundary part 4, the mask main body part 2 and the earring part 3 (left earrings) On the outer surface of the part 3a and the right ear part 3b], the information about the up-down direction of the mask 1 can be displayed by the emboss structure or other display structure (for example, printing structure). It may be.

(Sixth structure)

The sixth structure of the mask 1 will be described with reference to FIG. 14. 14, the figure explaining the 6th structure of the mask 1 is shown.

The sixth structure was developed on the basis of the review point 6 and has a decorative element attached to the outer surface of a mask body 2 on the outer surface of the mask body 2. . As a to-be-adhered member, the seal element which can paste | paste to the outer surface of the mask main-body part 2 is used typically.

Specifically, as shown in FIG. 14, the adherends S1 to S4 that can be joined to the outer surface of the mask body part 2 are disposed on the mount S. As shown in FIG. Each of the adherends S1 to S4 has a puzzle shape. For example, when each of the adherend members S1 to S4 is joined to a proper position of the outer surface of the mask body portion 2, the outer surface of the mask body portion 2 is formed to be almost completely covered by the adhered portions S1 to S4. It is. In other words, by appropriately disposing the adherent members S1 to S4, the shape formed by the adherent members S1 to S4 substantially coincides with the outer surface shape of the mask body 2. In addition, it is preferable that the adherends S1 to S4 have air permeability (air permeability) so that the wearer does not feel choked when worn.

By using the sixth structure, when the wearer is a child or the like, the child's interest in the mask can be enhanced. In addition, when the adherends S1 to S4 have a puzzle-like shape, an appropriate combination of the adherends S1 to S4 can be considered, and the function of intelligent training can be provided. As the adherend member, it is preferable to use an adherent member having a display that the child is interested in, for example, a display such as a character. In this case, as a to-be-adhered member S1-S4, the to-be-adhered member which has the same indication may be used, and the to-be-adhered member which has a different indication may be used. Alternatively, a single display may be divided into a plurality of partial displays, and a plurality of adhered members each having the divided partial displays may be used. In this case, when a plurality of adherends are appropriately arranged, the displays of the adherends are combined to form a single display. By using such a to-be-adhered member, interest, such as an eye with respect to a mask, can be heightened.

A state in which the child wears the mask 1 will be described with reference to FIG. 15. FIG. 15 is a view of the mask 1 as seen from the side of the child.

As shown in Fig. 15, the mask 1 is well adapted to the face of the child. For example, the width at the upper end side of the mask main body 2 is set to be shorter than the width at the lower end side, and the upper end of the mask main body 2 is more easily in surface contact with the wearer's nose. Thereby, when a wearer with a low nose and a high ball wears a mask like a child or a person with a small face, it can prevent effectively that a mask is twisted from an appropriate wearing position. Moreover, when improving the fitting property at the point of the nose of a general adult, it is possible to respond by using the mask of the shape which expanded the shape of the mask 1 which has the said 1st structure at least.

Also, for example, the top of the mask main body 2, that is, the top of the edge 2c, is disposed below the center of the mask 1 in the vertical direction, so that the mask main body 2 is between the wearer's mouth. The space around the mouth can be formed reliably. This can prevent the wearer from feeling unpleasant, such as choking.

Further, for example, the left earring hole 5a of the left earring part 3a and the right earring hole 5b of the right earring part 3b include the upper end part of the edge part 2c of the mask body part 2 and the mask body. It arrange | positions below the line which connects the upper end part of the boundary line between the part 2 and the earring part 3. As shown in FIG. This allows the wearer who wears a mask to have a short vertical gap between the nose and ears (more specifically, the vertical gap between the top of the nose root and the top of the ear root), such as a child or a person with a small face. In doing so, the mask main body 2 can be disposed at an appropriate wearing position.

For example, a plurality of holes 6 are provided in the earring part 3 (left earring part 3a and right earring part 3b). This makes it possible to prevent the wearer from feeling pain in the ear when the earring part 3 (the left earring part 3a and the right earring part 3b) is hooked on the ear (left ear and right ear). Moreover, the fiber density of the edge part of the hole 6 is higher than the fiber density of another point. Thereby, the return force of the earring part 3 (left earring part 3a and right earring part 3b) becomes large, and the earring part 3 (left earring part 3a and right earring part 3b) is increased. Can be prevented from increasing.

In addition, this invention is not limited to the structure demonstrated by embodiment, A various application and a deformation | transformation are possible.

Although the mask 1 provided with the 1st-6th structures was demonstrated, this invention can be comprised as a mask provided with at least 1 structure of the 1st-6th structures.

Although the three-dimensional mask which becomes a three-dimensional shape at the time of wearing a mask was demonstrated, each structure demonstrated in embodiment can also be used as the mask used in a planar state.

Although the mask main body part 2 was formed by heat-welding the other left sheet part 2a and the right sheet part 2b, the method of forming the mask main body part 2 is not limited to this. For example, after folding one sheet | seat and carrying out thermal welding at the point of the edge part 2c, the mask main body part 2 is cut | disconnected along the outer shape of the left seat part 2a and the right seat part 2b. It can be used to form a method. In addition, as a joining method, various well-known joining methods can be used.

In addition, although the separate left sheet portion 2a and the left earring portion 3a (the right sheet portion 2b and the right earring portion 3b) were heat-welded, the left sheet portion 2a and the left earring portion 3a ) (The right sheet part 2b and the right earring part 3b) may be integrally formed. When integrally formed, it is preferable that the characteristics of the left sheet portion 2a and the characteristics of the left earring portion 3a (the characteristics of the right sheet portion 2b and the characteristics of the right earring portion 3b) are different from each other. . For example, the left earring portion 3a is formed to be easier to stretch than the left sheet portion 2a (the right earring portion 3b is easier to stretch than the right sheet portion 2b). In this case, the boundary line between the left seat portion 2a and the left earring portion 3a and the boundary portion are used as the left boundary line 4a and the left boundary portion 4A, and the right sheet portion 2b and the right earring portion 3b are used. The boundary line between them and the boundary portion are used as the right boundary line 4b and the right boundary 4B.
