Description

本考案は、塵埃や細菌などの異物の混入を排除する衛生現場などで、関係者の口元を覆うために用いられる不織布製の使い捨て衛生マスクに関する。   The present invention relates to a disposable sanitary mask made of non-woven fabric that is used to cover the mouths of persons concerned in a sanitary field where foreign substances such as dust and bacteria are excluded.

病院では医師、歯科医師、看護師や食品製造工場などでは従業者が口元を覆う不織布製の衛生マスクを着用するようにしている。この種の衛生マスクは使い捨てマスクとして、伸縮性ウレタンシートや不織布を打ち抜いて口元や鼻孔部を覆う覆い部と耳掛け部とを別体や一体に形成している（例えば特許文献１、２、３参照）。
特開平９−１４９９４５号公報 特開平９−１４９９４６号公報 特開２００３−９３５２７号公報 At hospitals, doctors, dentists, nurses, and food manufacturing factories have employees wear non-woven sanitary masks that cover their mouths. This type of sanitary mask, as a disposable mask, is formed by separately forming a cover part and an ear hook part that cover a mouth and a nostril part by punching out a stretchable urethane sheet or nonwoven fabric (for example, Patent Documents 1 and 2; 3).
JP-A-9-149945 JP-A-9-149946 JP 2003-93527 A

特許文献１では、マスクの横方向の伸縮性を耳掛け部の伸縮性よりも低く設定し、耳掛け部が緊張状態になっても、マスクの覆い部が口元に密着しないようにしている。これにより、マスクの着用時に覆い部が左右に引っ張られても、息苦しさを感じないようになり、着用時の違和感が軽減されている。特許文献２では、覆い部と耳掛け部とを別々に形成し、耳掛け部が垂れ下がり難くするとともに、生産後に重ね合わせたマスク同士が密着しないようにしている。特許文献３では、使用時に二重マスクの内側カバーを外側カバーに取り付ける操作を不要にし、通常の一重マスクと同様に極めて着用し易い二重マスクを実現している。
ところが、特許文献１、２、３のいずれのマスクも、覆い部と耳掛け部との接合関係や覆い部と顔面との接触関係などについては解析されておらず、マスクの着用性や機能性において改善の余地が残されていた。 In Patent Document 1, the lateral stretchability of the mask is set to be lower than the stretchability of the ear hooking portion so that the mask covering portion does not adhere to the mouth even when the ear hooking portion is in tension. Thereby, even if a cover part is pulled right and left at the time of wearing of a mask, it will not feel breathlessness and the discomfort at the time of wearing will be reduced. In Patent Document 2, a cover part and an ear hook part are formed separately to make it difficult for the ear hook part to hang down and to prevent the masks that are overlapped after production from coming into close contact with each other. In patent document 3, the operation which attaches the inner cover of a double mask to an outer cover at the time of use is made unnecessary, and the double mask which is very easy to wear like a normal single mask is realized.
However, none of the masks of Patent Documents 1, 2, and 3 has been analyzed for the bonding relationship between the cover portion and the ear hook portion, the contact relationship between the cover portion and the face, and the wearability and functionality of the mask. There was still room for improvement.

本考案は上記の事情を考慮してなされ、その目的は覆い部に対する着用ゴム紐の接合関係などを改善して着用性や機能性を一段と向上させ、しかも製造コストが低下し安価で量産性に優れた使い捨て衛生マスクを提供することにある。   The present invention has been made in consideration of the above circumstances, and its purpose is to improve the wearability and functionality by improving the joining relationship of the worn rubber string to the cover part, and the production cost is reduced and the mass production is reduced. The object is to provide an excellent disposable sanitary mask.

（請求項１について）
カップ状の覆い部は、熱可塑性プラスチックであるポリプロピレン繊維の集合体を熱融着で形成した不織布により設けられている。着用ゴム紐は、耳部や後頭部に掛けるもので、覆い部の左右両外側部に超音波溶着により接合されている。覆い部に対する着用ゴム紐の接合領域は、着用ゴム紐を直径とする円形領域よりも放射方向に１０〜３０％だけ広い略円状のスポット部を形成している。覆い部から着用ゴム紐が延びる延出方向を、着用ゴム紐が耳部あるいは後頭部の引っ掛け部に結ばれる引出し方向の線上に合致させている。覆い部のうち着用ゴム紐で囲まれた周縁部分は凸状に広がる出張部を形成している。 (About claim 1)
The cup-shaped cover portion is provided by a nonwoven fabric formed by heat-sealing an aggregate of polypropylene fibers that are thermoplastics. The wearing rubber string is hung on the ear part or the back of the head, and is joined to the left and right outer parts of the cover part by ultrasonic welding. The joining region of the wearing rubber cord with respect to the covering portion forms a substantially circular spot portion that is 10-30% wider in the radial direction than the circular region having the wearing rubber cord as a diameter. The extending direction in which the wearing rubber cord extends from the cover portion is made to coincide with the line in the drawing direction in which the wearing rubber cord is tied to the hook portion of the ear portion or the back of the head. The peripheral part surrounded by the rubber band to be worn among the cover parts forms a business trip part spreading in a convex shape.

覆い部に対する着用ゴム紐の接合は超音波溶着により行われているため、溶着作業が短時間で済むとともに、接合強度が高く汚れがなく衛生的である。覆い部に対する着用ゴム紐の接合領域は、着用ゴム紐を直径とする円形領域よりも１０〜３０％だけ広いスポット部を形成しているため、接合強度が高く着用時に着用ゴム紐が繰り返し引っ張られても初期の良好な接合状態が保たれて安定する。また、スポット部が覆い部の外側部にあるため、着用時に溶着固化したスポット部が顔面の頬部などを擦る虞がなくなる。   Since the wearing rubber string is joined to the cover portion by ultrasonic welding, the welding work is completed in a short time, and the joining strength is high and there is no contamination and it is hygienic. The joining area of the wearing rubber cord to the covering portion forms a spot portion that is 10-30% wider than the circular area having the wearing rubber cord as a diameter, so that the wearing rubber cord is repeatedly pulled when worn because the joining strength is high. However, the initial good bonding state is maintained and stabilized. Further, since the spot portion is on the outer side of the covering portion, there is no possibility that the spot portion welded and solidified during wearing rubs the cheek portion of the face.

覆い部から着用ゴム紐が延びる延出方向を、着用ゴム紐が耳部あるいは後頭部の引っ掛け部に結ばれる引出し方向の線上に合致させているため、使い捨て衛生マスクの着用時に着用ゴム紐が無理な方向に引っ張られることがなくなり、良好な接合状態が長期にわたって保たれる。
覆い部のうち着用ゴム紐で囲まれた周縁部分は凸状に広がる出張部を形成していることから、頬部からこめかみ部にかけて覆い部の密着部分が増加し、覆い部による被覆性が向上する。これらの利点が協働して使い捨て衛生マスクの着用性や機能性を一段と向上させることができる。しかも、何ら新たな部材を付加せずに済み、製造コストが低下し安価で量産性に優れる。 The extending direction of the rubber band that extends from the cover is aligned with the line in the pull-out direction where the rubber band is connected to the hook of the ear or the back of the head. No longer being pulled in the direction, and a good bonding state is maintained for a long time.
Outer part of the cover surrounded by the rubber band to be worn forms a business trip part that expands in a convex shape, so that the close-contact part of the cover part increases from the cheek to the temple and the coverage by the cover part is improved. To do. Together, these advantages can further improve the wearability and functionality of the disposable sanitary mask. In addition, it is not necessary to add any new member, the manufacturing cost is reduced, and it is inexpensive and excellent in mass productivity.

（請求項２について）
ポリプロピレンの極細繊維の集合体を熱融着により形成し、メルトブローン（ＭＥＬＴ ＢＬＯＷＮ）型不織布を不織布の外側に重ね合わせて細菌濾過性および粒子濾過性を付与している。このため、使い捨て衛生マスクが、細菌濾過性および粒子濾過性を有する二層の形態となり、耐汚染性が向上して一層衛生的となる。 (About claim 2)
An aggregate of polypropylene microfibers is formed by heat fusion, and a melt-blown (MELT BLOWN) type nonwoven fabric is superimposed on the outside of the nonwoven fabric to impart bacterial filterability and particle filterability. For this reason, a disposable sanitary mask becomes a two-layer form which has bacteria filterability and particle | grain filterability, contamination | pollution resistance improves and it becomes more hygienic.

（請求項３について）
メルトブローン型（ＭＥＬＴ ＢＬＯＷＮ）不織布の外側に、ポリプロピレンの短繊維の集合体からなる最外側不織布をさらに重ね合わせて防水性および撥水性を付与している。このため、使い捨て衛生マスクが、防水性および撥水性を有する三層の形態となり、耐汚染性がさらに向上して格段に衛生的となる。
（請求項４について）
覆い部に対する着用ゴム紐の接合領域が着用ゴム紐の軸直角方向に長径を有する楕円領域になっている。このため、接合領域における着用ゴム紐の軸直角方向の断面積が増し引出し方向に対する接合強度が増加する。 (Claim 3)
An outermost nonwoven fabric made of an aggregate of polypropylene short fibers is further superimposed on the outside of a meltblown type (MELT BLOWN) nonwoven fabric to provide waterproofness and water repellency. For this reason, the disposable sanitary mask becomes a three-layered form having waterproofness and water repellency, and the contamination resistance is further improved and the sanitary mask becomes remarkably hygienic.
(About claim 4)
The joining area | region of the wearing rubber string with respect to a cover part is an elliptical area | region which has a long diameter in the axis orthogonal direction of a wearing rubber string. For this reason, the cross-sectional area in the direction perpendicular to the axis of the worn rubber string in the joining region increases, and the joining strength with respect to the drawing direction increases.

覆い部に対する着用ゴム紐の接合関係を考慮して、覆い部から着用ゴム紐が延びる延出方向を、着用ゴム紐が耳部や後頭部の引っ掛け部に結ばれる引出し方向の線上に合致させている。このため、着用時に着用ゴム紐が覆い部から無理な方向に引っ張られることがなくなり、良好な接合状態が長期にわたって保たれて着用性や機能性が一段と向上する。しかも、新たな部材を付加せずに済み製造コストが低下し安価で量産し易くなる。   In consideration of the bonding relationship of the wearing rubber cord to the covering portion, the extending direction in which the wearing rubber cord extends from the covering portion is matched with the line in the pulling direction where the wearing rubber cord is tied to the hook portion of the ear portion or the back of the head. . For this reason, the wearing rubber string is not pulled in an unreasonable direction from the covering portion at the time of wearing, and a good joined state is maintained for a long time, so that the wearability and functionality are further improved. Moreover, it is possible to reduce the manufacturing cost without adding a new member, and to easily mass-produce at a low cost.

本考案の実施例１を図１および図２に基づいて説明する。
図１の（イ）に示す使い捨て衛生マスク１において、カップ状の覆い部２は、熱可塑性プラスチックであるポリプロピレン繊維の集合体を熱融着で形成した不織布２ａにより構成されている。覆い部２の先端部は、上下方向に指向する熱融着部２ｂを形成し、使い捨て衛生マスク１の着用時に口元や鼻孔部に対して非接触空間を設けて使用者に息苦しさを感じさせないようにしている。
着用ゴム紐３は、覆い部２の左右両外側部に超音波溶着により接合されている。超音波溶着は、図示しない溶接ロッドを着用ゴム紐３の両端部３ａに押し当てて行う。覆い部２に対する着用ゴム紐３の接合領域は、図２に示すように着用ゴム紐３を直径Ｄとする円形領域よりも放射方向に１０〜３０％だけ広い略円状のスポット部Ｓｐを形成している。 A first embodiment of the present invention will be described with reference to FIGS.
In the disposable sanitary mask 1 shown in FIG. 1A, the cup-shaped cover portion 2 is composed of a nonwoven fabric 2a formed by heat-sealing an aggregate of polypropylene fibers that are thermoplastics. The front end portion of the cover portion 2 forms a heat fusion portion 2b oriented in the vertical direction, and when the disposable sanitary mask 1 is worn, a non-contact space is provided to the mouth and nostril portion so that the user does not feel breathless. I am doing so.
The wearing rubber string 3 is joined to the left and right outer portions of the cover portion 2 by ultrasonic welding. The ultrasonic welding is performed by pressing a welding rod (not shown) against both end portions 3 a of the wearing rubber string 3. As shown in FIG. 2, the joining region of the wearing rubber cord 3 to the covering portion 2 forms a substantially circular spot portion Sp that is 10-30% wider in the radial direction than the circular region having the wearing rubber cord 3 as the diameter D. doing.

この場合、平均的な体格および背格好の顔面サイズを想定し、使い捨て衛生マスク１の着用時、着用ゴム紐３が口元および鼻孔部から耳部４の引っ掛け部５に向く方向を引出し方向Ａとしている｛図１の（イ）参照｝。この条件のもとで、覆い部２から着用ゴム紐３が延びる延出方向Ｂを、着用ゴム紐３が耳部４の引っ掛け部５に結ばれる引出し方向Ａの線上に合致させるようにしている。この状態で、着用ゴム紐３の両端部３ａが超音波溶着により覆い部２に接合される。また、覆い部２のうち着用ゴム紐３で囲まれた周縁部分は凸状に広がる出張部６を形成している。
着用ゴム紐３は、耳部４の引っ掛け部５に限らず、図１の（ロ）に示すように、着用ゴム紐３を後頭部の引っ掛け部（図示せず）に回して掛けることもできる。この場合には、着用ゴム紐３の延出方向Ｂを、着用ゴム紐３が後頭部の引っ掛け部（図示せず）に結ばれる引出し方向Ａの線上に合致させる。 In this case, assuming the average physique and the face size of the appearance, when the disposable sanitary mask 1 is worn, the direction in which the worn rubber cord 3 faces the hook 5 of the ear 4 from the mouth and nostril is defined as the pulling direction A. {See (a) in FIG. 1}. Under this condition, the extending direction B in which the wearing rubber cord 3 extends from the cover portion 2 is made to coincide with the line in the pulling direction A in which the wearing rubber cord 3 is tied to the hook portion 5 of the ear portion 4. . In this state, both end portions 3a of the wearing rubber cord 3 are joined to the cover portion 2 by ultrasonic welding. Moreover, the peripheral part enclosed with the rubber band 3 to wear among the cover parts 2 forms the business trip part 6 which spreads convexly.
The wearing rubber cord 3 is not limited to the hooking portion 5 of the ear portion 4, and as shown in FIG. In this case, the extending direction B of the wearing rubber cord 3 is matched with a line in the pulling direction A where the wearing rubber cord 3 is tied to a hooking portion (not shown) on the back of the head.

上記構成では、覆い部２に対する着用ゴム紐３の接合は超音波溶着により行われているため、溶着作業が短時間で済むとともに、接合強度が高く汚れがなく衛生的でもある。覆い部２に対する着用ゴム紐３の接合領域は、着用ゴム紐３を直径Ｄとする円形領域よりも放射方向に１０〜３０％だけ広いスポット部Ｓｐを形成しているため、接合強度が高く耳掛け用ゴム紐３が繰り返し引っ張られても初期の良好な接合状態が保たれて安定する。   In the above configuration, since the wearing rubber string 3 is joined to the cover portion 2 by ultrasonic welding, the welding work can be completed in a short time, and the joining strength is high and there is no contamination and it is hygienic. The joining region of the wearing rubber cord 3 with respect to the covering portion 2 forms a spot portion Sp that is 10-30% wider in the radial direction than the circular region having the wearing rubber cord 3 as the diameter D. Even if the hanging rubber string 3 is repeatedly pulled, the initial good bonded state is maintained and stabilized.

また、覆い部２から着用ゴム紐３が延びる延出方向Ｂを、着用ゴム紐３が耳部４の引っ掛け部５や後頭部の引っ掛け部に結ばれる引出し方向Ａの線上に合致させるようにしている。このため、使い捨て衛生マスク１の着用時、着用ゴム紐３が無理な方向に引っ張られることがなくなり、良好な接合状態が長期にわたって保たれる。   Further, the extending direction B in which the wearing rubber cord 3 extends from the covering portion 2 is made to coincide with the line in the drawing direction A in which the wearing rubber cord 3 is tied to the hook portion 5 of the ear portion 4 or the hook portion of the back of the head. . For this reason, when the disposable sanitary mask 1 is worn, the worn rubber string 3 is not pulled in an unreasonable direction, and a good bonded state is maintained for a long time.

さらに、覆い部２のうち着用ゴム紐３で囲まれた部分は凸状に広がる出張部６を形成していることから、頬部からこめかみ部にかけて覆い部２の密着部分が増加し、覆い部２による被覆性が向上する。これらの利点が協働して使い捨て衛生マスク１の着用性や機能性を一段と向上させることができる。しかも、何ら新たな部材を付加せずに済み、製造コストが低下し安価で量産性に優れる。   Furthermore, since the portion surrounded by the wearing rubber strap 3 in the cover portion 2 forms a business trip portion 6 that extends in a convex shape, the close contact portion of the cover portion 2 increases from the cheek portion to the temple portion, and the cover portion The coverage by 2 is improved. Together, these advantages can further improve the wearability and functionality of the disposable sanitary mask 1. In addition, it is not necessary to add any new member, the manufacturing cost is reduced, and it is inexpensive and excellent in mass productivity.

図３は本考案の実施例２を示す。実施例２では、図３の（イ）に示す覆い部２において、ポリプロピレンの極細繊維の集合体を熱融着により形成し、図３の（ロ）に示すように、メルトブローン（ＭＥＬＴ ＢＬＯＷＮ）型不織布１０を不織布２ａの外側に重ね合わせて細菌濾過性および粒子濾過性を付与している。このため、使い捨て衛生マスク１が、細菌濾過性および粒子濾過性を有する二層の形態となり、耐汚染性が向上して一層衛生的となる。この場合、着用ゴム紐３は、超音波溶着によりメルトブローン型不織布１０に接合される。   FIG. 3 shows a second embodiment of the present invention. In Example 2, in the cover part 2 shown in FIG. 3 (a), an aggregate of polypropylene ultrafine fibers is formed by heat fusion, and as shown in FIG. 3 (b), a melt blown (MELT BLOWN) type The nonwoven fabric 10 is superposed on the outside of the nonwoven fabric 2a to impart bacterial filterability and particle filterability. For this reason, the disposable sanitary mask 1 becomes a two-layered form having bacterial filterability and particle filterability, and the contamination resistance is improved, which makes it more sanitary. In this case, the worn rubber string 3 is joined to the meltblown nonwoven fabric 10 by ultrasonic welding.

図４は本考案の実施例３を示す。実施例３では、図４の（イ）に示す覆い部２において、図４の（ロ）に示すメルトブローン型不織布１０の外側に、ポリプロピレンの短繊維の集合体からなる最外側不織布１１をさらに重ね合わせて防水性および撥水性を付与している。この一方、覆い部２に対する着用ゴム紐３の接合領域は、着用ゴム紐３の軸直角方向Ｆに長径を有する楕円領域１２になっている。
使い捨て衛生マスク１が、防水性および撥水性を有する三層の形態となり、耐汚染性がさらに向上して格段に衛生的となる。しかも、覆い部２に対する着用ゴム紐３の接合領域が楕円領域１２のため、接合領域における着用ゴム紐３の軸直角方向Ｆの断面積が増し、引出し方向Ａに対する接合強度が増加する。この場合、着用ゴム紐３は、超音波溶着により最外側不織布１１に接合される。 FIG. 4 shows a third embodiment of the present invention. In Example 3, the outermost nonwoven fabric 11 made of an aggregate of polypropylene short fibers is further stacked on the outer side of the meltblown nonwoven fabric 10 shown in FIG. 4B in the cover portion 2 shown in FIG. Together, it provides waterproofness and water repellency. On the other hand, the joining area | region of the wearing rubber cord 3 with respect to the cover part 2 has become the ellipse area | region 12 which has a long diameter in the axial perpendicular direction F of the wearing rubber cord 3. FIG.
The disposable sanitary mask 1 is in a three-layer form having waterproofness and water repellency, and the contamination resistance is further improved, so that it becomes extremely sanitary. And since the joining area | region of the wearing rubber cord 3 with respect to the cover part 2 is the ellipse area | region 12, the cross-sectional area of the axial direction F of the wearing rubber cord 3 in a joining area | region increases, and the joining strength with respect to the drawing-out direction A increases. In this case, the worn rubber string 3 is joined to the outermost nonwoven fabric 11 by ultrasonic welding.

図５は本考案の実施例４を示す。実施例４では、覆い部２における不織布２ａの厚み寸法ｔを比較的大きくして防塵性を高めたものである。   FIG. 5 shows a fourth embodiment of the present invention. In Example 4, the thickness dimension t of the nonwoven fabric 2a in the cover part 2 is made comparatively large, and dustproofness is improved.

図６は本考案の実施例５を示す。実施例５では、覆い部２の左右端部を薄肉の多孔性不織布１３により形成している。不織布２ａと多孔性不織布１３との繋ぎ目１４は、折り重ねた重複部１３ａを熱融着している。薄肉の多孔性不織布１３は、顔面の頬部に相当する位置にありながらも、通気性が良く柔らかいため頬部を擦らないし蒸らすこともない。   FIG. 6 shows Embodiment 5 of the present invention. In Example 5, the left and right end portions of the cover portion 2 are formed of a thin porous nonwoven fabric 13. The joint 14 between the nonwoven fabric 2a and the porous nonwoven fabric 13 is heat-sealed with the overlapped overlapping portion 13a. Although the thin porous nonwoven fabric 13 is in a position corresponding to the cheek part of the face, it does not rub or steam the cheek part because it has good breathability and is soft.

なお、使い捨て衛生マスク１は使用後に廃棄されるものであるが、軽作業の衛生現場や個人的使用などにあっては、使い捨て衛生マスク１を繰り返し使用しても差し支えない。 また、覆い部２に対する着用ゴム紐３の接合領域を楕円領域１２に設定する構成は、着用ゴム紐３を後頭部に掛ける場合にも適用することができる。   Although the disposable sanitary mask 1 is discarded after use, the disposable sanitary mask 1 may be used repeatedly in a light work sanitary field or personal use. Moreover, the structure which sets the joining area | region of the wear rubber string 3 with respect to the cover part 2 to the ellipse area | region 12 is applicable also when hanging the wear rubber string 3 on a back head.
