Description

  The present invention relates to a mask covering a target portion of a wearer's face including a nose and a mouth.

  A so-called pleated type mask is known as a mask for preventing dust, dust, pollen, microorganisms and the like from entering the body from the nose and mouth of the wearer. This mask has a mask main body part provided with pleats extending in the vertical direction and an ear hook part for locking the mask main body part to the ear, and the pleats spread in the vertical direction when worn. The mask body has a mountain-shaped three-dimensional shape. As a result, pressure on the nose and mouth of the wearer is suppressed and breathlessness is reduced, and when the wearer is a woman, there is an advantage that the lipstick applied to the lips does not easily adhere to the mask body. .

  In such a pleated type mask, pleat pressing portions for suppressing the spread of the pleats are formed linearly in the vertical direction on both sides of the mask main body in the left-right direction. Thereby, the pleats of the mask main body portion spread in the vertical direction only at the center side in the left-right direction of the pleat pressing portion when worn, and the spread is suppressed on the outer side in the left-right direction. As a result, the left and right side portions of the mask main body are pulled toward the center, and the distortion generated thereby creates a gap between the cheeks of the wearer at the left and right central portions of the mask main body, thereby reducing the mask function. Was the cause.

In order to suppress the formation of such a gap, a mask that has been devised in the form of pleat pressing portions on the left and right sides of the mask main body has been proposed (see, for example, Patent Document 1 and Patent Document 2).
The mask described in Patent Document 1 is formed by forming arc-shaped pleat pressing portions that bulge outward on the left and right sides of the mask main body. Thereby, the right and left both-side center part of a mask main-body part is changed to a wearer side at the time of wear, and suppression of the clearance gap formed between a wearer's cheek is aimed at.

  The mask described in Patent Document 2 forms a linear first pleat pressing portion extending in the vertical direction on both the left and right sides of the mask main body, and both the upper and lower sides from the vertical center position of the first pleat pressing portion. A second pleat pressing portion is formed in an oblique direction toward the edge of the. This prevents the spread of the pleats in the corner region of the mask main body sandwiched between the first and second pleat pressing portions, thereby improving the wearability at the corner portions.

  As described above, the pleat of the mask main body when worn is spread on the center side in the left-right direction with the pleat pressing portion as a boundary, and spread is suppressed on the outer side in the left-right direction. For this reason, stress is generated on the left and right side portions of the mask main body so as to bend the pleat pressing portion outward in the left-right direction at each pleat position.

  At this time, in the mask described in Patent Document 1, an arc-shaped pleat pressing portion that swells outward is formed across the pleats. Since the pleat pressing portion is curved in the direction opposite to the direction of the stress to bend the pleating pressing portion outward, the stress is not absorbed at each pleat position of the pleating pressing portion. , Concentrated in the center in the vertical direction on both the left and right sides of the mask body. As a result, an inflection point is formed between the two pleats positioned at the center in the vertical direction of the mask main body so that the uneven state of the pleat pressing portion changes due to the stress concentration. There is a possibility that distortions and gaps due to the inflection point may occur in the left and right side portions of the mask main body.

Moreover, in the mask of the said patent document 2, since the 2nd pleat pushing part becomes a substantially circular arc shape which expanded outward, and the said 2nd pleat pushing part is formed ranging over each pleat. As a result, the same problem as in Patent Document 1 is caused.
As described above, none of the masks described in Patent Document 1 and Patent Document 2 described above can sufficiently suppress the formation of gaps in the left and right side portions of the mask main body.

  The objective of this invention is providing the mask which can improve the suppression function of formation of the clearance gap in the right-and-left both sides part of a mask main-body part.

  In order to achieve the above object, a mask according to a first aspect of the present invention is a mask main body that covers a target portion of a wearer's face, and a pair of left and right ear hooks for locking the mask main body to the wearer's ear. A plurality of pleats capable of spreading in the vertical direction, and a pleat press formed on both sides of the mask main body for suppressing the spread of the pleats. And the pleat pressing part has a straight line part extending in the up-down direction and an arc part swelled outward in the left-right direction in series. And

The mask of the first invention of the present application is a so-called pleated type mask. That is, the target site | part of a wearer's face including a nose and a mouth is covered by expanding the pleat of a mask main-body part to an up-down direction at the time of wear.
Here, in the first invention of the present application, the pleat pressing portions formed on both sides of the mask main body in the left-right direction have a linear portion extending in the vertical direction and a circular arc portion swelled outward in the left-right direction in series. It is set as the structure which has. As a result, the uneven portion of the pleat pressing portion is formed at the boundary between the linear portion and the arc portion while the gap formed between the cheek of the wearer is suppressed by deforming the portion of the arc portion toward the wearer at the time of wearing. Inflection points that change can be formed. Since this inflection point is a boundary between the straight line portion extending in the vertical direction and the arc portion having a shape bulging outward in the left-right direction, the pleat pushing portion bends outward in the left-right direction at the inflection point. is doing. Therefore, the stress that tends to bend the pleat pressing portion in the same direction can be absorbed by the inflection point, so that the stress concentration on the left and right center portions of the mask main body portion can be reduced. As a result, it is possible to prevent the inflection point of the pleat pressing portion from being formed between the two pleats positioned at the center in the vertical direction of the mask main body, so that distortion and gaps are formed in the left and right side portions of the mask main body. Can be suppressed.

  The mask of the second invention is the above-mentioned first invention, wherein the pleat pressing portion is the arc portion provided between two pleats located on the center side in the vertical direction of the mask main body portion of the plurality of pleats; And the straight portions provided on both sides of the arc portion in the up-down direction.

Generally, when only the straight pleat pressing part is formed on both sides of the mask body part in the left and right direction, a gap is formed between the cheek of the wearer at the center part on both the left and right sides of the mask body part due to distortion generated during wearing. The mask function is degraded.
In the second invention of the present application, by providing an arc portion between two pleats positioned on the center side in the vertical direction of the mask main body portion, the portion of the arc portion is deformed to the wearer side when worn, and The gap formed in the part can be effectively suppressed.

  Moreover, it can be set as the structure by which an arc part does not straddle a pleat by providing an arc part between two pleats of the up-down direction center side. In other words, the shape of the arc portion that bulges outward in the left-right direction is curved in the direction opposite to the direction of the stress that attempts to bend the pleat pushing portion outward, so that the arc portion straddles the pleat. Cannot absorb the stress to bend the pleat pushing portion, but the above-described stress absorbing function can be improved by adopting a configuration in which the arc portion does not straddle the pleat as described above.

According to a third aspect of the present invention, in the first or second aspect of the invention, the pleat pressing portion is configured such that a boundary between the linear portion and the arc portion is a position corresponding to the pleat. Features.
In the third invention of the present application, the boundary between the straight line portion and the arc portion is made to correspond to the pleat position. As described above, an inflection point is formed at the boundary, and the pleat pushing portion is bent outward in the left-right direction at the inflection point. Therefore, by matching the position of the inflection point with the pleat position, The stress that tends to bend the pleat pressing portion in the same direction can be effectively absorbed.

The mask according to a fourth aspect of the present invention is the mask according to any one of the first to third aspects, wherein the ear hooking portion is attached to the mask main body portion by fixing an end portion thereof to a front side of the mask main body portion. It is characterized by being.
In 4th invention of this application, the edge part of an ear hooking part is attached to the front side (side opposite to a wearer side) of a mask main-body part. Thereby, compared with the case where the edge part of an ear hook part is attached to the back side (wearer side) of a mask main-body part, the edge part of a mask main-body part can be pressed on a wearer's cheek by the edge part of an ear hook part at the time of wear It is possible to further suppress the gap between the left and right side portions of the mask main body.

A mask according to a fifth aspect of the present invention is the mask according to any one of the first to fourth aspects, wherein the pleat pressing portion is formed on the mask main body so as to be doubled on both sides in the left-right direction of the mask main body. It is characterized by being.
In the fifth invention of the present application, the pleat pressing portions are formed in duplicate on both sides of the mask main body in the left-right direction. This increases the rigidity of the left and right side portions of the mask main body, and can further suppress distortion and gaps that occur during wearing. Moreover, compared with the case where only a single pleat pressing portion is formed, the contact area between the left and right side portions of the mask main body portion and the wearer's cheek can be increased, so that the wearing feeling can be improved.

  According to the present invention, it is possible to improve the function of suppressing the formation of gaps at the left and right side portions of the mask main body.

FIG. 3 is an enlarged partial cross-sectional view of a part of the side cross-section of the mask main body 2 shown in FIG. 4 and 5 are a perspective view and a side view showing the wearing state of the mask 1. In the following description, the terms “upper and lower” and “left and right” refer to the vertical and horizontal directions of the mask 1 when worn, and correspond to the vertical and horizontal directions in FIG. 1, respectively.

  As shown in FIG. 1, the mask 1 includes a mask main body 2 that covers a target portion of the wearer's face, and a pair of left and right ear hooks 3 for locking the mask main body 2 to the wearer's ears. have. As shown in FIGS. 1 and 2, pleats 4 a to 4 d that can spread in the vertical direction are formed in the mask body 2 in parallel at four locations in the vertical direction. As shown in FIGS. 4 and 5, when the pleats 4 a to 4 d are spread vertically when worn, the mask body 2 covers the target portion of the wearer's face including the nose, mouth and chin. ing.

  As shown in FIG. 3, the mask main body 2 includes an intermediate layer 5 and both side layers 6 provided on the front side (side opposite to the wearer side) and the back side (wearer side) with the intermediate layer 5 interposed therebetween. , 7. The intermediate layer 5 has a filter function and is made of, for example, a melt blown nonwoven fabric. Both side layers 6 and 7 are provided in order to give the mask main body 2 thickness and strength and to make the skin feel good because it directly contacts the wearer's skin. These both side layers 6 and 7 are comprised, for example with an air through nonwoven fabric, a spun bond nonwoven fabric, a spunlace nonwoven fabric, etc.

  The intermediate layer 5 may be coated with a fragrance, a drug having an antibacterial / antiviral effect, or the like. Examples of the drug having an antibacterial / antiviral effect include rose butts. Examples of the fragrances include menthol, carvone, cineol, limonene, pinene, camphor, linalool, turpineol, peppermint, spearmint, rosemary, lavender, tea tree, camomil, eucalyptus, orange, lemon, neroli, bergamot, petitgren and the like. It is done. The range in which these fragrances and chemicals are applied is not particularly limited, but when applied to the upper part, there is a risk that the chemicals may be seen when worn. It is preferable to apply to the intermediate layer 5 within the range.

  Returning to FIG. 1, on the both sides in the vertical direction of the mask main body 2, the joint portions 8 and 9 are formed such that the intermediate layer 5 and the both side layers 6 and 7 are joined by heat-sealing or the like. ing. The joint portion 8 formed on the upper end side includes an upper joint portion 8a and a lower joint portion 8b, and a nose base bar 10 is included between the joint portions 8a and 8b. This nose base bar 10 is made of a flexible material, and is formed between the upper part of the mask body 2 and the nose by being deformed so as to conform to the shape of the wearer's nose at the time of wearing. A gap can be suppressed. Although not particularly provided in the present embodiment, the movement of the nose base bar 10 may be limited by forming a joint portion around the nose base bar 10 by heat fusion or the like.

  Further, on both sides in the left-right direction of the mask main body 2, similarly to the above, the joint portions 20 in which the intermediate layer 5 and the both side layers 6, 7 are joined by heat fusion or the like are formed to be double. The joint portion 20 is provided to suppress the spread of the pleats 4a to 4d on both sides in the left-right direction of the mask main body portion 2, and corresponds to the pleat pressing portion described in the claims. As shown in FIGS. 1, 4, and 5, the joint portion 20 includes a straight portion 21, 22 extending in the vertical direction and a circular arc portion 23 swelled outward in the left-right direction in series in the vertical direction. Have. The arc portion 23 is provided between two pleats 4 b and 4 c located on the center side in the vertical direction of the mask main body portion 2 among the four pleats 4 a to 4 d, and the linear portions 21 and 22 are arranged above and below the arc portion 23. It is provided on both sides in the direction. Further, the joint portion 20 is configured so that the inflection point 24 formed at the boundary between the arc portion 23 and the straight portions 21 and 22 is at a position corresponding to each of the two pleats 4b and 4c. The inflection point 24 is a point where the uneven state of the joint 20 changes. As shown in FIGS. 1, 4, and 5, the joint 20 is directed outward in the left-right direction at the inflection point 24. It is bent.

  As shown in FIGS. 1, 4 and 5, the ear hook 3 is joined to the front side (the side opposite to the wearer) of the mask main body 2 by heat fusion or the like. As a result, the mask body 2 is attached. At this time, as shown in FIG. 1, the attachment positions of the upper ends 3a of the left and right ear hooks 3 to the mask body 2 are different in the vertical direction. That is, the joint portions 8a and 8b are formed at positions shifted from each other in the left-right direction, and the upper end portion 3a of the ear hook portion 3 on one side (left side in FIG. 1) is in parallel with the upper joint portion 8a. At the same time, it is joined to the lower joint 8b so as to partially overlap in the left-right direction. On the other hand, the upper end 3a of the ear hook 3 on the other side (right side in FIG. 1) is parallel to the lower joint 8b and joined so as to partially overlap the upper joint 8a in the left-right direction. Has been. With such a configuration, the adhesion of the upper portion of the mask body 2 is improved.

  In addition, the ear hook part 3 is a string-like member which has elasticity, for example, is comprised with spandex (polyurethane elastic fiber). In this embodiment, a string-like member whose cross-sectional shape is not a round shape but a flat plate shape is used as the ear hooking portion 3, and the contact area with the wearer's skin is increased to act on the ears and cheeks when worn. To improve the fit.

Next, effects obtained by the mask 1 configured as described above will be described using a comparative example.
FIG. 6 is a front view of a mask 1 ′ as a first comparative example, and FIG. 7 is a perspective view showing a wearing state of the mask 1 ′.
As shown in FIG. 6, arc-shaped joints 20 'bulging outward are formed on the left and right sides of the mask body 2' of the mask 1 '. Unlike the mask 1 of the present embodiment, the joint portion 20 ′ does not have a straight portion, and is formed in a uniform arc shape between the pleats 4 a and 4 d. The configuration other than the above is the same as that of the mask 1 of the present embodiment. With this configuration, when the mask 1 'is worn, the gap formed between the cheek of the wearer by deforming the left and right center portions of the mask body 2' to the wearer side as shown in FIG. It is possible to suppress this.

  Here, as shown in FIG. 7, the pleats 4 a to 4 d of the mask main body 2 ′ at the time of wearing are widened on the center side in the left-right direction with the joint 20 ′ as a boundary, and spread is suppressed on the outer side in the left-right direction. . For this reason, stress is generated on the left and right side portions of the mask main body 2 'so as to bend the joint 20' outward in the left-right direction at each pleat position. Such stress is similarly generated in the mask 1 of the present embodiment.

  At this time, in the mask 1 'of the first comparative example, the joint portion 20' is formed so as to straddle the pleats 4b and 4c. Since this joint 20 'is curved in a direction opposite to the direction of the action of the stress to bend the joint 20' outward, the stress corresponds to the pleats 4b and 4c of the joint 20 '. Instead of being absorbed at the position, it concentrates in the center in the vertical direction on both the left and right sides of the mask body 2 '. As a result, as shown in FIG. 7, an inflection point 24 'where the uneven state of the joint 20' changes is formed between the pleats 4b, 4c on the center side in the vertical direction of the mask body 2 '. As a result, distortions and gaps caused by the inflection point 24 'are generated in the left and right side portions of the mask body 2'.

  On the other hand, in the mask 1 of the present embodiment, as described above, the joint portions 20 provided on both sides in the left-right direction of the mask main body portion 2 include the linear portions 21 and 22 and the arc portion 23 in series. Yes. Thereby, in the circular arc part 23, like the said 1st comparative example, as shown in FIG.4 and FIG.5, as shown in FIG.4 and FIG.5, the part of the said circular arc part 23 is changed to a wearer side at the time of wear, The inflection point 24 described above can be formed at the boundary between the straight portions 21 and 22 and the arc portion 23 while suppressing the gap formed therebetween. Since the inflection point 24 is a boundary between the straight line portion 21 extending in the vertical direction and the arc portion 23 having a shape bulging outward in the left-right direction, the joint portion 20 has the inflection point 24 as described above. Are bent outward in the left-right direction. Therefore, the inflection point 24 can absorb the stress that causes the joint 20 to be bent in the same direction, and the stress concentration at the left and right center portions of the mask body 2 can be reduced. As a result, as shown in FIGS. 4 and 5, it is possible to prevent inflection points from being formed between the pleats 4 b and 4 c on the center side in the vertical direction of the mask main body 2. It is possible to suppress the occurrence of distortion and gaps.

  It is also conceivable to make cuts in the left and right edges of the mask body in order to absorb the stress that causes the joint 20 described above to bend toward the outside in the left-right direction at each pleat position. FIG. 8 is a front view of a mask 1 ″ as a second comparative example having such a configuration. As shown in FIG. 8, the left and right edges of the mask main body 2 ″ of the mask 1 ″ are shown in FIG. In addition, a cut-out portion 30 is formed, and linear joint portions 20 "are formed on both the left and right sides of the mask main body portion 2". The configuration other than the above is the same as that of the mask 1 of the present embodiment. is there.

  In the mask 1 ″ of the second comparative example, the above-described stress can be absorbed by the cut portion 30, but it is necessary to add a process of forming the cut portion 30 to the mask manufacturing process. In addition, the cut portion 30 may hit the cheek of the wearer during wearing, which may cause a reduction in wearing feeling, whereas the mask 1 of the present embodiment has the above-described problem without complicating the manufacturing process. The stress can be absorbed, and since the notch is not formed, the wearing feeling is not lowered.

  Further, in the present embodiment, in particular, the arc portion 23 is provided between the two pleats 4 b and 4 c located on the center side in the vertical direction of the mask main body portion 2. Thus, when only the straight joint portions are formed on both sides in the left-right direction of the mask main body 2, the gap formed in the center portions on both the left and right sides is effectively changed by deforming the arc portion 23 to the wearer side. Can be suppressed. Further, by providing the arc portion 23 between the pleats 4b and 4c, the arc portion 23 can be configured so as not to straddle any of the pleats 4a to 4d. In other words, the shape of the arc portion 23 bulging outward in the left-right direction is curved in the direction opposite to the direction of the stress acting to bend the joint portion 20 outward, so that the arc portion 23 is pleated. When straddling 4a-4d, the stress which is going to bend the junction part 20 cannot be absorbed, but the above-mentioned stress is obtained by adopting a configuration in which the arc part 23 does not straddle the pleats 4a-4d as described above. Can improve the absorption function.

  In the present embodiment, in particular, the boundary between the straight portions 21 and 22 and the arc portion 23 is configured to correspond to the positions of the pleats 4b and 4c. As described above, the inflection point 24 is formed at the boundary, and the joint portion 20 is bent outward in the left-right direction at the inflection point 24, so that the position of the inflection point 24 and the pleats 4 b and 4 c By matching the position, it is possible to effectively absorb the stress that causes the joint 20 to be bent in the same direction.

  In the present embodiment, the end 3 a of the ear hook 3 is particularly attached to the front side of the mask body 2. Thereby, compared with the case where the edge part 3a of the ear hook part 3 is attached to the back side (wearer side) of the mask main body part 2, the edge part of the mask main body part 2 is worn by the end part 3a of the ear hook part 3 at the time of wearing. And the gap between the left and right side portions of the mask main body 2 can be further suppressed. Further, in the present embodiment, as described above, the attachment position of the upper end 3a of the left and right ear hooks 3 to the mask main body 2 is varied in the vertical direction, and the end 3a is connected to any of the joints 8a and 8b. It joins so that it may overlap partially in the left-right direction. By setting it as such a structure, the adhesiveness of the upper part of the mask main-body part 2 can be improved, and formation of the clearance gap in the said upper part can be suppressed. Moreover, as a result of suppressing the formation of the gap in the upper portion of the mask main body 2 as described above, it is possible to suppress the occurrence of inconvenience such as the medicine applied to the intermediate layer 5 being seen by the wearer as described above.

  In the present embodiment, in particular, the joint portions 20 are doubled on both sides of the mask main body 2 in the left-right direction. Thereby, the rigidity of the right-and-left both sides part of the mask main-body part 2 can be increased, and the distortion and clearance gap which arise at the time of wear can be suppressed further. Moreover, since the contact area between the left and right side portions of the mask main body 2 and the cheek of the wearer can be increased as compared with the case where only the single joining portion 20 is formed, it is possible to improve the wearing feeling.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention.
For example, in the above embodiment, the case where the number of pleats is four has been described. However, the number of pleats is a preferable example, and the number of pleats is not particularly limited as long as it is two or more, regardless of whether it is odd or even. . Moreover, the form of the pleats is not limited to the apex at the center in the vertical direction of the mask main body 2 as shown in FIG. 2. For example, the lower side (or the upper side) of the mask main body 2 may be the apex as shown in FIG. It may be a form that becomes.

  In the above embodiment, the nose bar 10 is provided, but a mouth bar may be further provided. The mouth bar is made of a flexible material like the nose bar 10 and is provided to eliminate contact between the wearer's mouth and the mask body 2. Thereby, when a wearer is a woman, for example, adhesion of a lipstick to mask body part 2 can be prevented. The mouth bar is provided between the pleats 4b and 4c on the center side in the vertical direction of the mask main body 2, for example.

Moreover, in the said embodiment, although joined part 8,9,20 was formed by heat sealing | fusion, it is not restricted to this, For example, you may form a joined part by sewing. In this case, the intermediate layer 5 and the both side layers 6 and 7 constituting the mask main body 2 can be made of a material other than a thermoplastic material.
In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.
In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
