Description

Application for application of Article 30, Paragraph 2 of the Patent Act (1) On May 24, 2nd year of Reiwa, Chikusa Mihara visited the website (http://www.azurite-style.com, https: //store.shopping. The mask according to the present invention has been disclosed as "an antibacterial cooling mask capable of nasal breathing" on yahoo.co.jp/azuritestyle/). (2) On May 24, 2nd year of Reiwa, Chise Mihara sold the mask according to the present invention as "antibacterial cooling mask that can breathe through the nose" at Sogo Yokohama store.

The present invention relates to a mask.

Conventionally, a mask provided with pleats has been known (for example, Patent Document 1). Patent Document 1 states, "By spreading the pleats in the vertical direction and wearing them, the mask body has a mountain-shaped three-dimensional shape, and a space is formed around the wearer's nose and mouth, making it easier to breathe. ".

However, the conventional mask with pleats is configured to be substantially flat before the pleats are unfolded, and even if the pleats are unfolded, a natural three-dimensional shape cannot be formed, especially near the nose. There was a tendency to press, and the space formed around the nostrils was narrow, making it difficult to breathe through the nose.

It is a front view which shows the embodiment of the mask by this invention. It is a bottom view which shows the embodiment of the mask by this invention. It is a side view which shows the embodiment of the mask by this invention. It is a figure which shows the unfolded state of the main body part 1 before sewing in the form of a pattern.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings and the like.

(Embodiment)
FIG. 1 is a front view showing an embodiment of a mask according to the present invention.
FIG. 2 is a bottom view showing an embodiment of the mask according to the present invention.
FIG. 3 is a side view showing an embodiment of the mask according to the present invention.
It should be noted that each figure shown in this embodiment is a diagram schematically shown, and the size and shape of each part are shown by being exaggerated or omitted as appropriate for easy understanding.
Further, in the following description, specific numerical values, shapes, materials and the like will be described, but these can be changed as appropriate.
Further, in the following description, the orientations such as up / down, left / right, front / back, etc. will be appropriately used with reference to the wearer wearing the mask. In addition, these directions are also shown in the figure.

The mask 10 of the present embodiment includes a main body portion 1, a second main body portion 2, a pleated holding portion 3, and an ear hook portion 4.

The main body 1 is configured to be large enough to cover at least the nose and mouth of the wearer's face. Various cloths such as polyester can be appropriately used for the main body 1.
At each of the left and right ends of the main body 1, a pleated portion 1a in which each end is partially folded is provided. In the present embodiment, the pleated portions 1a are provided at four locations on each of the left and right sides, but the number of the pleated portions 1a may be appropriately changed.

The second main body portion 2 is overlapped on the back surface side (wearer side) of the main body portion 1. The second main body portion 2 is made of a material different from that of the main body portion 1. Various cloths such as polyester can be appropriately used for the second main body 2. Further, in the present embodiment, the second main body portion 2 is made of a mesh-like material to improve the touch.
The main body 1 and the second main body 2 are connected by a pleated holding portion 3 at the left and right ends, are connected at the lower end, and open at least a part of the upper end without being connected. There is. As a result, the main body portion 1 and the second main body portion 2 are connected to each other on the entire circumference other than the opening portion, and the whole is in the shape of a pocket. Therefore, for example, a cold touch sheet or the like can be inserted into the pocket-shaped gap. As the cold touch sheet, various cloths such as polyester having appropriate water retention and breathability can be appropriately used. Further, a non-woven fabric filter sheet or the like may be inserted into the pocket-shaped gap between the main body portion 1 and the second main body portion 2 to improve the filter performance (capture performance of viruses, bacteria, dust, etc.). ..

The pleated holding portion 3 holds the folded state of the pleated portion 1a. In the present embodiment, the pleated holding portion 3 holds both the main body portion 1 and the second main body portion in a folded state.

The ear hooks 4 are provided on the left and right sides of the main body 1. More specifically, both ends of the elastic string-shaped member inserted into the insertion passage 3a (see FIG. 2) configured by the pleated holding portions 3 attached to the left and right sides of the main body portion 1 are It is composed by tying.

FIG. 4 is a diagram showing the unfolded state of the main body portion 1 before sewing in the form of a paper pattern.
In FIG. 4, L1, L2, and L3 are shown at the positions constituting the pleated portion 1a, and the folding positions are shown. L3 drawn diagonally between L1 and L2 conforms to the notation of the pattern used for sewing, and means that L1 is bent according to the position of L2.
As shown in FIG. 4, in the deployed state, the width (length) WC in the left-right direction at the center of the main body 1 in the vertical direction is the length WT of the ridgeline in the left-right direction at the upper end of the main body 1 and the main body. The length of the ridgeline in the left-right direction at the lower end of 1 is longer than the length WB. Then, the raw fabric cut out in such a shape is sewn by the pleats holding portion 3 so that the left and right ends are substantially aligned with the pleats folded. Therefore, in the form after the mask 10 is sewn, that is, in the worn state, the length of the horizontal ridgeline at the center of the main body 1 in the vertical direction is the length of the horizontal ridgeline at the upper end of the main body 1. WT and the length of the ridge line in the left-right direction at the lower end of the main body portion are longer than the length WB (see FIG. 2). Therefore, as shown in FIG. 2, the shape of the mask 10 in the worn state when viewed from above and below is a three-dimensional shape protruding forward.

The difference in length between the length WC and the length WT is preferably 1 cm or more and 3 cm or less.
Further, it is desirable that the difference in length between the length WC and the length WB is 3.5 cm or more and 5.5 cm or less.
By setting the above range, a natural three-dimensional shape can be obtained.
In the present embodiment, WT = 15 cm, WL = 12.5 cm, and WC = 17 cm are set within the above range.

Further, at the left and right ends where the pleats are folded, the pleated state folded by the pleated holding portion 3 is maintained, whereas in the central portion, there is no configuration like the pleated holding portion 3. , The fabric of the main body 1 is in a naturally unfolded state. Therefore, as shown in FIG. 3, when the mask 10 is worn, the length HC of the vertical ridgeline at the center of the main body 1 in the left-right direction is the length HL of the vertical ridgeline at the left end of the main body 1. , And the length of the vertical ridgeline at the right end of the main body 1 is longer than the length HR. Therefore, as shown in FIG. 3, the shape of the mask 10 when viewed from the left and the right is a three-dimensional shape protruding forward. The effect of changing the length of the ridgeline in the vertical direction is the same as that of the conventional pleated mask.

The conventional mask with pleats is configured to be substantially flat before the pleats are unfolded, and by unfolding the pleats, the vertical ridge length at the center of the mask is larger than the vertical ridge length at the left and right ends. However, the length of the ridgeline in the left-right direction at the center of the mask was the same as the length of the ridgeline in the left-right direction at the upper and lower ends.
On the other hand, in the mask 10 of the present embodiment, as described above, in addition to the conventional three-dimensional effect by changing the length of the ridgeline in the vertical direction, the three-dimensional shape by changing the length of the ridgeline in the left-right direction. The effect of conversion is further provided. Due to these synergistic effects, the mask 10 of the present embodiment naturally forms a dome-shaped shape protruding forward. As a result, a vast space can be naturally secured around the nostrils of the wearer, and nasal breathing can be easily performed.

Further, in Patent Document 1, "when the mask main body portion is expanded in the vertical direction, the vicinity of the center portion in the horizontal direction of the mask main body portion expands in the vertical direction, but the vicinity of the left and right end portions does not expand in the vertical direction. Due to the distortion caused by this, a gap was formed between the wearer's cheek and the wearer's cheek in the vicinity of the central portion in the vertical direction on both the left and right sides of the mask main body, which caused the deterioration of the mask function. " ing.
On the other hand, in the mask 10 of the present embodiment, since the three-dimensional effect is further provided by changing the length of the ridge line in the left-right direction, the entire main body portion 1 naturally becomes a dome-shaped shape and is worn. There is almost no gap between the floor and the cheek.

In addition, it is difficult to create a dome-shaped space with the so-called "three-dimensional mask" (mask sewn in the center) that has been used conventionally, and it becomes an acute-angled mountain-shaped space under the nose, or there is a gap. Sometimes it was too much. Furthermore, with the conventional "three-dimensional mask", the cheeks are often too compressed to breathe through the nose.
On the other hand, since the position of the mask 10 of the present embodiment is fixed by the chin and cheeks, the upper part of the nose is not pressed only by the cloth, and it is easy to breathe through the nose.

Further, in the wearing state of the mask 10, the length WB of the ridgeline in the left-right direction at the lower end of the main body 1 is shorter than the length WT of the ridgeline in the left-right direction at the upper end of the main body 1. As a result, when the mask is worn, the upper end side is naturally closer to the ear than the lower end side. Therefore, the tension due to the ear hook portion 4 tends to be weaker in the upper part than in the lower part. Due to this difference in tension, it is possible to suppress the mask 10 from pressing the vicinity of the nose, and it is possible to obtain a wearing feeling as if the mask is lightly placed, and it becomes easier to breathe through the nose.
