Description

  The present invention relates to a three-dimensional non-woven mask, and more particularly to a three-dimensional non-woven mask having excellent fit when worn.

  2. Description of the Related Art Conventionally, there is known a mask in which a plurality of folds are folded in a pleated shape in a mask main body in order to enhance fit during mounting. The wrinkles of such a mask are generally provided in parallel with the width direction of the mask, and when they are opened, the mask has a three-dimensional shape in which a portion covering the nose and the mouth of the wearer is expanded. Become. Thereby, the wearer of the mask can obtain a good fit.

  However, although the conventional mask provides an excellent fit as compared to a mask having no wrinkles, the fitter may feel a lack of fit particularly around the nose. For example, a conventional mask tends to generate a gap between the nose and the mask, which strikes the upper part of the nose, and when the glasses are worn with the mask, the wearer's breath is likely to cause fogging of the glasses. . In addition, a gap is created between the mask and the cheek, and as a result, the filter effect on pollen and viruses may be reduced.

  This invention was made in order to solve the above subjects, and it aims at providing the three-dimensional nonwoven fabric mask excellent in the fitting property at the time of mounting | wearing.

This invention is a three-dimensional non-woven mask comprising a mask main body formed of non-woven fabric and straps respectively provided on both sides in the width direction of the mask main body to achieve the above object,
The mask body is
A plurality of buttocks including the outer bending portion and the inner bending portion extending in the width direction;
And a seal unit for fixing the plurality of non-woven fabrics overlapping each other at the buttocks,
The seal portion is characterized in that the seal portion is provided at a position located on both sides of the nose bone of the wearer.

  According to this invention, the wearer can wear the three-dimensional non-woven mask so that the mask body covers the nose and the mouth by putting the strap around the ear. The buttocks provided on the mask body are held in an unopened state by the seal around the wearer's nose bone. As a result, in the portion covering the nasal bone, the mask body maintains a linear outline in the vertical direction. Since the outer shape fits along the nose, a gap is unlikely to occur between the nose and the mask body. On the other hand, in the area where the seal portion is not provided, the outer shape of the mask main body becomes three-dimensional with a bulge by opening the buttocks. This contour forms a suitable space or reservoir around the mouth and nose wings while fitting the mask body to the wearer's cheeks. For this reason, according to the present invention, it is possible to provide a three-dimensional non-woven mask excellent in fit when worn.

It is a figure which shows the external appearance at the time of mounting | wearing of the three-dimensional nonwoven fabric mask which concerns on 1st Embodiment of this invention. FIG. 2A is a plan view of the initial state of the three-dimensional non-woven mask shown in FIG. 1 viewed from the outside. FIG. 2B is a plan view of the initial state of the three-dimensional non-woven mask shown in FIG. 1 as viewed from the inside. It is a figure which shows the name around a nose part. FIG. 4A is a side view showing the appearance of the three-dimensional non-woven mask shown in FIG. 1 when worn. FIG. 4B is a side view showing the appearance of the mask of the comparative example when worn.

Embodiment 1
FIG. 1 shows the appearance of a three-dimensional non-woven mask 10 according to a first embodiment of the present invention. The mask 10 of the present embodiment has a mask body 12. The mask body 12 is made of non-woven fabric. Straps 14 are attached to both ends of the mask main body 12 in the width direction.

  The mask body 12 includes a plurality of ridges 16 extending in the width direction. These ridges 16 are configured by a combination of an outer bending portion formed by folding the nonwoven fabric outward and an inner bending portion formed by folding the nonwoven fabric inward.

  The four sides, that is, the four ends of the mask body 12 are subjected to processing such as stitching. For this reason, the ridges 16 can not be opened near both ends in the width direction of the mask body 12. And the collar part 16 will be in the state which is easy to open as it approaches center vicinity from near both ends of the width direction. FIG. 1 shows the outer shape of the mask 10 in which the central portion is extended to form a three-dimensional shape by the flange portion 16 provided in the lower half of the mask body 12 opening particularly wide near the center in the width direction There is.

  In the three-dimensional nonwoven fabric mask 10 of the present embodiment, the seal portion 18 is provided on the mask body 12. The mask body 12 is made of, for example, a material that can be welded, such as polypropylene. The seal portion 18 is realized by locally fixing a plurality of non-woven fabrics overlapping each other in the ridge portion 16 by ultrasonic seal welding by an electric welding method. Since the seal portion 18 adheres the overlapping non-woven fabrics to each other, the ridge portion 16 does not open at the portion where the seal portion 18 is formed, and the outer and inner folds thereof are maintained substantially in the initial state.

  Further, the mask body 12 is provided with a shape maintenance material 20. The shape maintaining member 20 is a member for maintaining the shape of the mask main body 12 in a shape that follows the unevenness of the face of the wearer, and is made of a material capable of elastic deformation and maintaining the shape after deformation. . The shape maintenance material 20 is embedded at an upper end near the widthwise center of the mask main body 12 with a predetermined width.

Hereinafter, the features of the seal portion 18 will be further described with reference to FIGS. 2 and 3.
FIG. 2 is a view for explaining the position where the seal portion 18 is formed. More specifically, FIG. 2 (A) is a diagram showing the three-dimensional nonwoven fabric mask 10 in the initial state in plan view from the outside. Moreover, FIG. 2 (B) is the figure which showed the three-dimensional nonwoven fabric mask 10 of the initial state by the planar view from inner side.

  FIG. 3 is a diagram showing names of the nose and the vicinity where the mask 10 is attached. Hereinafter, as shown in FIG. 3, the base of the nose between the two eyes is the “nose”, the line extending from the nose to the tip of the nose, ie, the line formed by the nose bone The part that bulges to the left and right ends is referred to as the "nasal wing", and the entrance of the nose, that is, between the nose and the upper lip is referred to as the "nasal vestibule".

  As shown in FIGS. 2A and 2B, the seal portion 18 is provided such that the nonwoven fabric of the mask body 12 penetrates and welds from the outside to the inside. A plurality of non-woven fabrics overlap each other at each location where the seal portion 18 is provided, also due to the structure of the ridge portion 16. The seal portion 18 fixes all of them locally.

  Further, as shown in FIGS. 2A and 2B, the seal portion 18 is provided on the back of the nose of the mask wearer, that is, on the both sides of the nasal bone. In particular, in the present embodiment, a plurality of, specifically two, seal portions 18 are provided on both sides of the nasal bone so as to be symmetrical with respect to the nasal bone. The width of the nose usually extends from the nose to the wing. In accordance with this, in the present embodiment, the distance between the left and right seal portions 18 provided on the nose wing side is set wider than the distance between the left and right seal portions 18 provided on the nasal root side.

  Further, in the present embodiment, the seal portion 18 prevents the opening of the buttocks 16 on both sides of the nose of the wearer, and does not impair the opening of the buttocks 16 around the mouth of the wearer. I'm asking. For this reason, the seal portion 18 is not provided in the lower 1/3 region, more preferably the lower 1/2 region, of the mask main body 12 which covers the periphery of the mouth of the wearer. That is, in the present embodiment, the seal portion 18 is provided in the upper 2/3 region, more preferably in the upper 1/2 region of the mask body 12.

  FIG. 4 is a view comparing the shape of the three-dimensional nonwoven fabric mask 10 of the present embodiment at the time of wearing and the shape of the mask 30 of the comparative example at the time of wearing. More specifically, FIG. 4A is a side view showing the appearance of the three-dimensional non-woven mask 10 according to the present embodiment when attached. Moreover, FIG. 4 (B) is the figure which represented the external appearance at the time of mounting | wearing of the mask 30 of a comparative example by the side view.

  As shown to FIG. 4A, in the three-dimensional nonwoven fabric mask 10 of this embodiment, opening of the collar part 16 is suppressed in the upper side of the mask main body 12 by the function of the seal part 18. As a result, the area 22 covering the nose and back has a linear shape similar to that of the nasal bone. However, in the area sandwiched by the left and right seal parts 18, since the freedom in the opening direction is left in the collar part 16, in the area 22, the mask main body 12 is appropriate according to the shape of the nose of the wearer. A three-dimensional shape can be realized. In addition, since the seal portion 18 is not provided on the lower side of the mask main body 12, in the area covering the mouth, the curved portion 16 is secured by opening the collar portion 16.

  The mask 30 of the comparative example is a mask provided with the ridge portion 16 but not provided with the seal portion 18. In the case of the mask 30 of the comparative example, as shown in FIG. 4B, the ridge portion 16 can be opened in the height direction in the entire area of the mask main body 12 near the center in the width direction. For this reason, the appearance of the mask 30 has a generally curvilinear bulge from the area to cover the nose to the area to cover the chin.

  According to the three-dimensional non-woven mask 10 of the present embodiment, as described above, an appropriate three-dimensional shape along the nasal bone can be formed around the nose by the function of the seal portion 18. For this reason, according to this mask 10, a remarkably superior fit can be realized around the nose portion as compared with the mask 10 of the comparative example.

  Further, according to the three-dimensional non-woven mask 10 of the present embodiment, the opening of the buttocks 16 is suppressed even in the region covering the cheeks of the wearer on both sides of the nose by the function of the sealing portion 18. As a result, the fit on the cheek of the mask body 12 is improved. Furthermore, since the lift of the mask at the cheek portion is reduced, the loss of breath above the mask is reduced, the problem of fogging when wearing glasses is improved, and the filter effect of the mask is also improved.

Hereinafter, the functions and effects of the three-dimensional non-woven mask 10 of the present embodiment will be summarized from another viewpoint.
In the present embodiment, the comfort (feel, air permeability, moisture permeability) and functionality when wearing the three-dimensional non-woven mask 10 are sought.

(1) Stability of Shape A stable shape that fits the wearer's face is realized with a soft strap 14 without a sense of excessive pressure.
(2) Improvement of Breathability A reservoir is formed inside the nose wings of the mask body 12 so that the nose wings are not blocked with a non-woven fabric and are easy to breathe.
(3) Improvement of Virus Blocking Effect Since the mask body 12 fits the wearer's face, it is difficult to form a gap on both sides of the face and up and down, and air leakage and intrusion of pollen and virus can be prevented.
(4) Reduction of fogging when wearing glasses Because there is no gap between the mask body 12 and the area around the nose, when wearing glasses, there is no leakage of breath inside the glasses and fogging of the glasses with breathing is eliminated or Reduced.
