Description

本考案は、浮遊する塵埃や花粉などの体内への吸い込みを防止する粉塵防止マスクに関するものである。   The present invention relates to a dust prevention mask that prevents inhalation of floating dust and pollen into the body.

昨今、花粉症を患う人が増加し、また、中国からの黄砂や粉塵の到来の問題から、外出時にはマスクを着用する人が著しく増加している。また、従来から粉塵が浮遊する作業現場では、空気中に漂う粉塵の吸い込みにより作業する人の健康が害されるのを防止すべくマスクを着用する。このようなマスクは、通常、長方形の平面な形状をしており、マスクに取付けた係止バンドを耳部に係止させて、鼻部から口部の表面にマスクを当てるように着用する。
しかし、長方形の平面な形状のマスクの場合、マスク着用者の鼻部から口部まで当着させ、係止バンドを耳部に係止させてマスクを緊張させたとしても、鼻部から口部へかけての表面の凹凸面のために、鼻の両側部とマスクの上縁部との間に隙間ができやすく、この隙間から外部の粉塵や花粉がマスク内へ侵入するといった問題がある。
In recent years, the number of people suffering from hay fever has increased, and the number of people wearing masks has increased remarkably when going out due to the arrival of dust and dust from China. Also, at work sites where dust has conventionally floated, a mask is worn to prevent the health of the worker from being harmed by inhalation of dust floating in the air. Such a mask usually has a rectangular flat shape, and is worn so that a locking band attached to the mask is locked to the ear portion and the mask is applied from the nose portion to the surface of the mouth portion.
However, in the case of a mask with a rectangular flat shape, even if the mask wearer is worn from the nose to the mouth and the mask is tensioned by locking the locking band to the ear, the mouth to the mouth Due to the uneven surface on the surface, there is a problem that a gap is easily formed between both sides of the nose and the upper edge of the mask, and there is a problem that external dust and pollen enter the mask through this gap.

上記問題点に鑑みて、鼻部より口部までを被覆可能に形成された通気性生地体と、通気性生地体の周縁部に設けられ鼻部や口部の表面に同通気性生地体を密着させる貼着部と、が設けられた防塵マスクが知られている(特許文献1)。
また、肌に密着させることを目的として、高粘弾性の粘着剤がマスクの基布の周辺部で顔に接する部分に設けられているマスクが知られている(特許文献2)。特許文献2に開示されたマスクでは、マスクの基布の周辺部で顔に接する部分に、高粘弾性の粘着剤が設けられているが、その例として、マスクの基布の全周に設けられている実施例が説明されている。高粘弾性の粘着剤は皮膚に密着できればよく、高粘弾性の粘着剤の量及び形態は適宜調節されるものであり、その例として、高含水性のジェルや、マスクの基布の上側周辺部に鼻が入る凹部を形成させたものが実施例として説明されている。
なお、粉塵や花粉など微小な物質がマスク内へ侵入することを防止する目的ではないが、紐やゴムを用いなくても顔面からの脱落を防止できることを目的として、マスクの周縁部全周に、顔に密着させるための粘着部を備えたマスクが知られている(特許文献3)。
In view of the above problems, a breathable fabric body formed so as to be able to cover from the nose portion to the mouth portion, and the breathable fabric body provided on the periphery of the breathable fabric body on the surface of the nose portion and the mouth portion. There is known a dust mask provided with a sticking part to be brought into close contact with (Patent Document 1).
In addition, a mask is known in which a highly viscoelastic adhesive is provided on a portion of the mask base fabric that is in contact with the face for the purpose of adhering to the skin (Patent Document 2). In the mask disclosed in Patent Document 2, a high-viscosity adhesive is provided on the peripheral portion of the mask base fabric in contact with the face. As an example, the mask is provided on the entire circumference of the mask base fabric. The described embodiment has been described. The high viscoelastic pressure-sensitive adhesive is only required to adhere to the skin, and the amount and form of the high viscoelastic pressure-sensitive adhesive can be adjusted as appropriate. For example, a high water content gel or the upper periphery of the mask base fabric An example in which a recess into which the nose enters is formed in the part is described.
It is not intended to prevent fine substances such as dust and pollen from entering the mask, but it can be applied to the entire periphery of the mask to prevent it from falling off the face without using a string or rubber. A mask having an adhesive portion for closely contacting the face is known (Patent Document 3).

しかし、特許文献1〜3に開示されたマスクでは、粉塵や花粉など微小な物質がマスク内へ侵入することを防止するために、顔に密着する部分であるマスク周縁部全周に粘着剤を設けているため、マスクの取付け、取り外し作業が簡便に行い難いという問題があった。
マスクを取付ける際、マスク周縁部全周に粘着剤があると、粘着剤同士が触れないようにしてマスクを取り付ける必要がある。
また、マスクを取り外すは、顔の皮膚に着いた粘着剤を拭き取る必要がある。
このように、マスク周縁部全周に粘着剤を設けたマスクでは、マスクの装着・脱着作業が煩雑となる。
上記状況に鑑みて、本考案は、マスクの取付け、取り外し作業が簡便に行え、粉塵や花粉など微小な物質がマスク内へ侵入しにくい安価なマスクを提供することを目的とする。
However, in the masks disclosed in Patent Documents 1 to 3, in order to prevent a minute substance such as dust or pollen from entering the mask, an adhesive is applied to the entire periphery of the mask peripheral part, which is a part closely contacting the face. Therefore, there is a problem that it is difficult to easily attach and remove the mask.
When attaching the mask, if there is an adhesive around the entire periphery of the mask, it is necessary to attach the mask so that the adhesives do not touch each other.
In order to remove the mask, it is necessary to wipe off the adhesive on the facial skin.
As described above, in the mask in which the adhesive is provided on the entire periphery of the mask, the mounting / demounting operation of the mask becomes complicated.
In view of the above situation, an object of the present invention is to provide an inexpensive mask that can be easily attached and detached, and in which minute substances such as dust and pollen do not easily enter the mask.

上記目的を達成すべく、本考案者は、マスク周縁部全周に粘着剤を設けるのではなく、マスク上辺部で、鼻骨から左右の鼻翼溝および鼻翼基部に至る皮膚を覆う部分にのみ粘着剤を設けることで、効果的に粉塵や花粉など微小な物質がマスク内へ侵入することを防げることの知見を得た。また、肩紐やアンダーベルトが不要で、シリコン素材の粘着性と弾力性を利用して、胸の素肌に直接貼りつけて使用するブラジャーであるヌーブラ(登録商標)などに用いるシリコン素材をマスクに圧着して取り付けることが可能であるという知見を得た。   In order to achieve the above object, the present inventor does not provide an adhesive on the entire periphery of the mask, but only on a portion covering the skin from the nasal bone to the right and left nasal grooves and the base of the nose wings on the upper side of the mask. It was found that it was possible to effectively prevent minute substances such as dust and pollen from entering the mask. In addition, it eliminates the need for shoulder straps and underbelts and uses the silicone material used for Nubra (registered trademark), which is a brassiere that is applied directly to the bare skin of the chest, using the adhesiveness and elasticity of silicone material as a mask. The knowledge that it can be attached by crimping was obtained.

すなわち、本考案のマスクは、長方形平面状マスクの基布の上辺部で、鼻骨から左右の鼻翼溝および鼻翼基部に至る皮膚を覆う部分に、シリコン素材の帯状粘弾性粘着シートが連続して圧着されていることを特徴とする。
ここで、シリコン素材は、胸の素肌に直接貼りつけて使用するブラジャーに用いるような皮膚への刺激が低く、皮膚への粘着性と弾力性があり、顔の凹凸形状に柔軟に対応して皮膚表面と粘着できるものである。
このようなシリコン素材は、マスクの基布に対して圧着して取り付けることが可能である。マスクの上辺部にシリコン素材を圧着させることで、マスクの上辺部に選択的にシリコン素材の粘着性と弾力性を付与できる。
That is, in the mask of the present invention, a band-like viscoelastic adhesive sheet made of a silicon material is continuously crimped on the upper side portion of the base fabric of the rectangular planar mask and covering the skin from the nasal bone to the right and left nasal groove and the nasal wing base. It is characterized by being.
Here, the silicone material has low skin irritation, such as that used for brassiere that is directly attached to the bare skin of the breast, has adhesiveness and elasticity to the skin, and flexibly corresponds to the uneven shape of the face. It can adhere to the skin surface.
Such a silicon material can be attached to the base fabric of the mask by pressure bonding. By bonding the silicon material to the upper side of the mask, the adhesiveness and elasticity of the silicon material can be selectively imparted to the upper side of the mask.

また、上述の通り、マスク上辺部で、鼻骨から左右の鼻翼溝および鼻翼基部に至る皮膚を覆う部分にのみ粘着剤を設けることで、効果的に粉塵や花粉など微小な物質がマスク内へ侵入することを防げることから、マスク周縁部全周ではなく、上辺部にのみ顔の皮膚と粘着できるようにする。マスクの左右の縁部、下辺部は、従来の長方形平面状マスクと同じであり、顔と完全に密着しないで若干の隙間が生じるが、従来の長方形平面状マスクが、左右に長いことや、耳部に係止させる係止バンドによりマスクを緊張させていることから、左右から粉塵や花粉などがマスク内へ侵入する可能性が低い。また、マスクを着用した場合、顔の顎部でマスクが屈曲することになり、下辺部から粉塵や花粉などがマスク内へ侵入する可能性も低い。   In addition, as described above, by providing an adhesive only on the upper part of the mask that covers the skin from the nasal bones to the right and left nasal grooves and the base of the nasal wing, fine substances such as dust and pollen effectively enter the mask. Therefore, it is possible to adhere to the skin of the face only on the upper side, not on the entire periphery of the peripheral part of the mask. The left and right edges and the lower side of the mask are the same as the conventional rectangular flat mask, and a slight gap is produced without completely adhering to the face, but the conventional rectangular flat mask is long on the left and right, Since the mask is tensioned by the locking band that is locked to the ear portion, there is a low possibility that dust, pollen, and the like enter the mask from the left and right. Further, when the mask is worn, the mask is bent at the chin portion of the face, and there is a low possibility that dust, pollen and the like enter the mask from the lower side.

また、上記の粘着シートの形状が、左右の鼻翼溝に位置する部分の上下幅が、他の部分よりも幅広であることがより好ましい。
左右の鼻翼溝に位置する部分が、マスクと顔の皮膚との間に最も隙間が生じやすい個所である。この左右の鼻翼溝に位置する部分を他の部分よりも幅広にすることにより、顔の皮膚との密着性をより高めることができる。
Moreover, as for the shape of said adhesive sheet, it is more preferable that the vertical width of the part located in a right and left nose wing groove is wider than another part.
The portions located in the left and right nose wing grooves are the places where the gap is most likely to occur between the mask and the facial skin. By making the part located in the right and left nose wing grooves wider than the other parts, the adhesion to the skin of the face can be further enhanced.

また、上記の粘着シートの形状が、5〜20mmの範囲の上下幅の帯状であることが更に好ましい。
粘着シートの上下幅が5mm未満であると、顔の皮膚との密着性が低く、隙間が生じる可能性があり、また、粘着シートの上下幅が20mmより大きいと顔の密着範囲が広くなりすぎて、マスク装着の快適感が低下する。
Moreover, it is more preferable that the shape of the above-mentioned pressure-sensitive adhesive sheet is a strip shape having a vertical width in the range of 5 to 20 mm.
If the adhesive sheet has a top and bottom width of less than 5 mm, the adhesion to the face skin is low and a gap may be formed. If the adhesive sheet has a top and bottom width of more than 20 mm, the face adhesion range becomes too wide. This reduces the comfort of wearing the mask.

本発明のマスクにおいて、マスクの基布の上辺部であって、上記粘着シートが設けられていない上辺端部が4〜7mmの範囲であり、該上辺端部が外側に折り返され、マスク表面と折り返し面との挟角が20〜40°であることが好ましい。
折り返し部分を設けることにより、マスクから出た吐息に含まれる水蒸気が上方へ上るのを折り返し部分で効果的にブロックでき、眼鏡の曇りを防止できる。
In the mask of the present invention, the upper edge of the mask base fabric, the upper edge where the adhesive sheet is not provided is in the range of 4 to 7 mm, the upper edge is folded outward, and the mask surface and The included angle with the folded surface is preferably 20 to 40 °.
By providing the folded portion, it is possible to effectively block the water vapor contained in the breath exhaled from the mask from rising upward at the folded portion, thereby preventing fogging of the glasses.

本考案のマスクによれば、マスクの取付け、取り外し作業が簡便に行え、かつ、粉塵や花粉の吸い込みを効果的に低減できるといった効果を有する。また、粘着シートを上辺部のみに圧着して取付けるため、製造コストが低減できる。   According to the mask of the present invention, it is possible to easily attach and remove the mask, and to effectively reduce the suction of dust and pollen. In addition, since the pressure-sensitive adhesive sheet is attached by pressure bonding only to the upper side portion, the manufacturing cost can be reduced.

The scope of the present invention is not limited to the following examples and illustrated examples, and many changes and modifications can be made.

図1,2を参照して、実施例1のマスクについて説明する。
図1に示すように、実施例1のマスクは、長方形平面状のマスクの基布2の上辺部に、シリコン素材の帯状粘弾性粘着シート4が連続して圧着されている。
実施例1のマスク1は、係止バンド3を耳部に係止させてマスクを緊張させて、マスク着用者の鼻部から口部まで当着させる。マスクを着用した場合、図2に示すように、鼻骨から左右の鼻翼溝Aおよび鼻翼基部Bに至る皮膚を覆う部分に粘着シート4が位置し、鼻骨から左右の鼻翼溝Aおよび鼻翼基部Bに至る皮膚に密着することになる。粘着シート4はシリコン素材であり、シートの幅は10mmである。粘着シート4の素材は、弾性・粘着性があり、皮膚に低刺激のものを使用する。弾性・粘着性があり、皮膚に低刺激のものであれば、シリコンとポリウレタンの混合材を用いてもよい。
実施例1のマスクは、マスクの上辺部のみに粘着シート4が設けられているため、マスクの取付け、取り外し作業が簡便に行うことができる。また、粉塵や花粉の吸い込みを効果的に低減できる。
また、形状保持できるように、柔軟性の樹脂からなる棒や、アルミ箔などの補助材を粘着シート4に沿って設けても構わない。
The mask of Example 1 will be described with reference to FIGS.
As shown in FIG. 1, in the mask of Example 1, a band-like viscoelastic pressure-sensitive adhesive sheet 4 made of a silicon material is continuously bonded to the upper side portion of a base cloth 2 of a rectangular planar mask.
In the mask 1 of the first embodiment, the locking band 3 is locked to the ear portion to tension the mask, and the mask wearer is attached from the nose portion to the mouth portion. When the mask is worn, as shown in FIG. 2, the adhesive sheet 4 is located in a portion covering the skin from the nasal bone to the right and left nasal sulcus A and the nasal wing base B, and from the nasal bone to the right and left nasal sulcus A and the nasal wing base B. It will be in close contact with the skin. The adhesive sheet 4 is a silicon material, and the width of the sheet is 10 mm. The material of the pressure-sensitive adhesive sheet 4 is elastic and sticky, and uses a material that is mild to the skin. A mixture of silicon and polyurethane may be used as long as it is elastic and adhesive and has low skin irritation.
Since the mask of Example 1 is provided with the adhesive sheet 4 only on the upper side of the mask, the mask can be easily attached and detached. In addition, the suction of dust and pollen can be effectively reduced.
Moreover, you may provide auxiliary | assistant materials, such as a stick | rod made from a flexible resin, and aluminum foil, along the adhesive sheet 4 so that shape holding | maintenance can be carried out.

図3を参照して、実施例2のマスクについて説明する。
実施例2のマスクでは、実施例1のマスクと異なり、粘着シート4の左右の鼻翼溝に位置する部分の上下幅が、粘着シート4の他の部分よりも幅広である。
左右の鼻翼溝に位置する部分(5a,5b)は、マスクと顔の皮膚との間に最も隙間が生じやすい個所であり、この左右の鼻翼溝に位置する部分を他の部分よりも幅広にすることにより、顔の皮膚との密着性をより高める。左右の鼻翼溝に位置する部分(5a,5b)の上下幅は18mmであり、他の部分の上下幅は10mmである。
With reference to FIG. 3, the mask of Example 2 is demonstrated.

By doing so, the adhesion to the skin of the face is further enhanced. The vertical width of the parts (5a, 5b) located in the left and right nose wing grooves is 18 mm, and the vertical width of the other parts is 10 mm.

図4,5を参照して、実施例3のマスクについて説明する。
実施例3のマスクは、マスクの基布の上辺部であって、粘着シート4が設けられていない上辺端部が5mmであり、その上辺端部が外側に折り返され、図4に示すように折り返し部7を構成する。
マスク表面と折り返し面との挟角は、略30°に調整している。
折り返し部7を設けることにより、図5に示すように、マスクから出た吐息9に含まれる水蒸気(9a,9b,9c)が上方へ上るのを折り返し部7で効果的にブロックできるので、眼鏡レンズ8の曇りを効果的に防止可能である。
The mask of Example 3 will be described with reference to FIGS.
