Description

【０００１】
【発明の属する技術分野】
この発明はマスクに関し、さらに詳しくは、病院、食品等の製造工場、塵埃の多い作業現場などで使い捨てのものとして使用するのに好適なマスクに関する。
【０００２】
【従来の技術】
特開平９−１４９９４５号公報には、不織布等の伸縮性シートを使用して、着用者の少なくとも口もとに対する覆い部と、該覆い部の対向両側から後方へ延びる耳掛け部とを一体的に形成した使い捨て衛生マスクが開示されている。この種マスクは、それを組立てるための手間が不要であるからその分だけコストがかからず、使い捨てマスクとして好適である。
【０００３】
【発明が解決しようとしている課題】
前記公知のマスクは、それを着用して耳掛け部が伸長されるときに、耳掛け部を支えている耳殻の基部でも耳掛け部が伸長されて、そのときの張力を基部の比較的狭い範囲で受け止めらなければならないことがある。そうした場合には、耳掛け部が緊張状態になると、人によって、耳に痛みを感じることがある。この発明の課題は、このような痛みを解消することが可能なマスクを提供することにある。
【０００４】
【課題を解決するための手段】
前記課題解決のために、この発明が前提とするのは、着用者の口もとに対する覆い部と、該覆い部の対向側から後方へ延びる耳掛け部とからなるマスクである。
【０００５】
かかる前提において、この発明が特徴とするところは、前記耳掛け部が非弾性的に伸長可能な繊維からなる非弾性的に伸長可能な伸長層と弾性伸縮性を有する弾性層とを積層一体化してなる弾性伸縮可能な複合シートからなっていて、前記非弾性的に伸長可能な繊維が熱可塑性合成樹脂からなり、少なくとも７０％の破断伸度を有していること、にある。
【０００６】
かかるこの発明には、次のような好ましい実施態様がある。
（１）前記非弾性的に伸長可能な繊維が、ポリプロピレンの連続繊維、エチレン−プロピレン共重合体の連続繊維およびエチレン−プロピレン−ブテン共重合体の連続繊維のいずれかである態様。
（２）前記弾性伸縮可能な複合シートが、前記弾性層と該弾性層の両面に形成された前記伸長層とからなる態様。
【０００７】
【本発明の実施の形態】
添付の図面を参照して、以下にこの発明に係るマスクの詳細を説明する。
【０００８】
図１に斜視図で示されたマスク１は、着用者の口もとに対する覆い部２と覆い部２の両側それぞれから後方へ延びていて、耳通し用の孔４を有する耳掛け部３とからなる。覆い部２は、熱可塑性かつ伸縮性または非伸縮性で左右対称な一対の第１シート１１からなり、それらの外側縁１３を重ね合わせて溶着接合することにより形成されている。耳掛け部３は、熱可塑性かつ弾性伸縮可能なシート１２からなり、第１シート１１の内側縁１２に溶着接合することによって形成されている。覆い部２の接合部である内外側縁１２，１３は、加熱加圧下の溶着によって、覆い部２および耳掛け部３の他の領域よりも剛性であって、マスクの保形機能を有する。
【０００９】
図２は、図１のＩＩ−ＩＩ線断面図である。耳掛け部３を形成している第２シート１２は、マスク着用者の肌に対する当接面を形成している弾性伸縮可能な弾性層１６と非当接面を形成している非弾性的に伸長可能な伸長層１７とが重なり合い、一体化したものである。図示例の弾性層１６は、弾性伸縮性の繊維からなり、少なくとも口もとから耳へ向かう１方向に弾性伸縮性を有する繊維層である。弾性層１６の外側に位置する伸長層１７は、少なくとも口もとから耳へ向かう１方向に非弾性的に伸長可能な繊維層である。これら両層１６，１７は、それぞれを形成している繊維が熱で互いに溶着することによって、または接着剤で接着することによって、または機械的に絡み合うことによって、互いに接合一体化して複合シートを形成している。かかる耳掛け部３は、これを両手に持って少なくとも一部分を前記の１方向に伸長すると、その一部分において弾性層１６が弾性的に伸長すると同時に、伸長層１７が非弾性的に伸長する。耳掛け部３から手を放して伸長を解くと、その一部分では弾性層１６がもとの寸法にまで弾性的に戻り、伸長層１７は伸びてしまった繊維が多数のひだを生じながら、弾性層１６の寸法にまで縮む。その一部分を再び伸長するときには、伸長層１７はひだが伸びるだけであって殆ど伸長力を必要とせず、弾性層１６を伸長するための力だけで足りる。このようにして、耳掛け部３は、一部分だけが弾性的に伸縮容易なものになる。
【００１０】
つまり、耳掛け部３は、一度伸長した部分が未だ伸長していない部分に比べて低応力で伸縮できる領域となるから、その領域を利用して、マスク着用者は自分の顔に最もよく合うように耳掛け部３の長さを設定したり、伸縮する範囲を設定したりすることができる。特に、口もとと耳殻の基部との中間で耳掛け部３が伸縮容易であるようにすれば、ゴム紐等で作られて全体が伸縮する従来の耳掛け部のように耳殻の基部でも紐が伸縮するということがなく、耳に痛みを感じたりすることもない。
【００１１】
耳掛け部３は、図示例に代えて、弾性層１６が外側となり、伸長層１７が肌に当接する内側となるようにすることもできる。多数の繊維からなる伸長層１７は、一度伸長されると多数のひだが生じ、嵩だかで肌触りが良くなるから、このような繊維層が内側になることは極めて好ましいといえる。また弾性層１６は、その肌触りがゴムライクになりがちで、そのような肌触りを好まないマスク着用者もあるから、この意味において弾性層１６が外側になることは好ましい。
【００１２】
図３は、耳掛け部３の一例を示す図２と同様の図面である。この図の耳掛け部３は、３層構造の弾性伸縮可能な複合シートで形成されており、弾性層１６の両面に伸長層１７を有する。耳掛け部３は、その一部分を口もとと耳との間で前後方向へ伸長すると、弾性層１６が弾性的に伸長し、伸長層１７が非弾性的に伸長する。伸長を解けば、弾性層１６がもとの寸法にまで弾性的に戻り、伸長層１７は伸長した部分に多くのひだを生じながら、弾性層１６と同じ長さにまで縮む。かかる耳掛け部３も、図１、２のそれと同じように作用する。
【００１３】
図４は、図１と異なる態様のマスク１の平面図である。このマスク１では、覆い部２と耳掛け部３とが、図２または図３で耳掛け部３に使用された弾性伸縮可能な１枚の複合シートで一連に形成されている。このマスク１もまた、耳掛け部３を予め前後方向（図の左右方向）に部分的に伸長してから着用する。図４のマスク１は、製造が簡単でかつ着用感のよいもので、使い捨てのものとして好適である。
【００１４】
この発明において、マスク１の少なくとも耳掛け部３とするための弾性伸縮可能な複合シートの弾性層１６は、ウレタンを一例とする熱可塑性合成樹脂のエラストマー等からなる弾性糸を使用した不織布、織布、不定形の繊維ウェブ等で形成する他に、弾性伸縮性のフィルムで形成することもできる。弾性層１６は、１方向に対して少なくとも３０％、より好ましくは少なくとも１００％、さらに好ましくは２００％弾性的に伸長可能であることが好ましい。もう一方の伸長層１７には、ポリエチレンやポリプロピレン等の熱可塑性合成樹脂からなり、非弾性的に伸長可能な糸が使用される。かかる糸は、不織布、織布、不定形の繊維ウェブ等の形態で弾性層１６に接合される。伸長層１７は、少なくとも７０％の破断伸度を有し、弾性層１６が弾性的に伸長できる限界と同程度か、それ以上に伸長できることが好ましい。伸長層１７の具体例として、未延伸または低延伸率のポリプロピレン連続繊維を互いに溶着してなる坪量２０〜２００ｇ／ｍ２の不織布、エチレン−プロピレン共重合体やエチレン−プロピレン−ブテン共重合体等の連続繊維を互いに溶着してなる坪量２０〜２００ｇ／ｍ２の不織布をあげることができる。
【００１５】
【発明の効果】
この発明に係るマスクは、耳掛け部の一部分だけを伸縮容易にすることができるから、その一部分の範囲を予め広く、または狭く設定しておくことによって、マスク着用者が耳掛け部の張力を自分に適合するように調整できる。その伸縮容易な一部分が、口もとと耳との間に位置するように設定されれば、マスク着用者の耳殻の基部で耳掛け部が伸縮することはなく、マスクが心地よい着用感のものとなる。

BACKGROUND OF THE INVENTION
The present invention relates to a mask, and more particularly to a mask suitable for use as a disposable one in a hospital, a manufacturing factory for foods, a dusty work site, or the like.
[0002]
[Prior art]
In JP-A-9-149945, a stretchable sheet such as a non-woven fabric is used to integrally form a cover portion for at least the mouth of the wearer and an ear hook portion extending rearward from opposite sides of the cover portion. A disposable sanitary mask is disclosed. Since this type of mask does not require labor for assembling it, it does not cost much and is suitable as a disposable mask.
[0003]
[Problems to be solved by the invention]
In the known mask, when the ear hook is worn and the ear hook is extended, the ear hook is also extended at the base of the ear shell that supports the ear hook, and the tension at that time is relatively reduced to the base. It may be necessary to accept within a narrow range. In such a case, when the ear hook is in tension, some people may feel pain in the ear. The subject of this invention is providing the mask which can eliminate such a pain.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention presupposes a mask comprising a cover portion for the wearer's mouth and an ear hook portion extending rearward from the opposite side of the cover portion.
[0005]
Under such a premise, the present invention is characterized in that the ear hooking portion is formed by laminating and integrating an inelastically stretchable stretch layer made of inelastically stretchable fibers and an elastic layer having elastic elasticity. such elastic stretchable composite sheet comprising Te Ttei Te, said inelastically stretchable fibers made of thermoplastic synthetic resin, to have a breaking elongation of at least 70%, in.
[0006]
This invention has the following preferred embodiments.
(1) The aspect in which the inelastically stretchable fiber is any one of a continuous fiber of polypropylene, a continuous fiber of an ethylene-propylene copolymer, and a continuous fiber of an ethylene-propylene-butene copolymer.
(2) A mode in which the elastically stretchable composite sheet is composed of the elastic layer and the stretched layer formed on both surfaces of the elastic layer.
[0007]
[Embodiments of the Invention]
Details of the mask according to the present invention will be described below with reference to the accompanying drawings.
[0008]
A mask 1 shown in a perspective view in FIG. 1 includes a cover 2 for the wearer's mouth and an ear hook 3 that extends rearward from both sides of the cover 2 and has a hole 4 for passing through the ear. . The cover 2 is composed of a pair of first sheets 11 that are thermoplastic, stretchable, or non-stretchable and symmetrical, and is formed by overlapping and welding the outer edges 13 thereof. The ear hook 3 is made of a thermoplastic and elastically stretchable sheet 12 and is formed by welding and joining to the inner edge 12 of the first sheet 11. The inner and outer edges 12 and 13 which are joint portions of the cover portion 2 are more rigid than other regions of the cover portion 2 and the ear hook portion 3 by welding under heat and pressure, and have a shape retaining function of the mask.
[0009]
2 is a cross-sectional view taken along line II-II in FIG. The second sheet 12 forming the ear hook 3 is inelastically forming a non-contact surface with an elastic layer 16 that is elastically stretchable and forms a contact surface with the mask wearer's skin. The stretchable layer 17 that can be stretched overlaps and is integrated. The elastic layer 16 in the illustrated example is made of elastic stretchable fiber and is a fiber layer having elastic stretchability in at least one direction from the mouth toward the ear. The stretchable layer 17 located outside the elastic layer 16 is a fiber layer that can stretch inelastically in at least one direction from the mouth to the ear. These two layers 16 and 17 are joined together to form a composite sheet by the fibers forming each of them being welded to each other by heat, by bonding with an adhesive, or mechanically entangled with each other. is doing. When the ear hook 3 is held in both hands and at least a part is extended in the one direction, the elastic layer 16 is elastically extended in the part and the extension layer 17 is inelastically extended. When the extension is released by releasing the hand from the ear hook 3, the elastic layer 16 returns elastically to the original dimensions in a part thereof, and the stretched layer 17 is elastic while generating a large number of pleats. Shrink to the dimensions of layer 16. When a part of the elastic layer 16 is stretched again, the stretched layer 17 is stretched only by a pleat and hardly requires a stretching force, and only a force for stretching the elastic layer 16 is sufficient. In this way, only a part of the ear hook 3 is elastically easily stretchable.
[0010]
In other words, the ear hook 3 is a region where the stretched portion can be stretched with low stress compared to the portion that has not been stretched, and the mask wearer best fits his / her face using this region. In this way, the length of the ear hook 3 can be set, or the range of expansion and contraction can be set. In particular, if the ear hook 3 can be easily stretched between the mouth and the base of the ear shell, the ear shell base can be made like a conventional ear hook made of rubber straps and the like. There is no expansion and contraction of the string, and there is no pain in the ear.
[0011]
Instead of the illustrated example, the ear hooking portion 3 can be configured such that the elastic layer 16 is on the outside and the stretched layer 17 is on the inside in contact with the skin. Since the stretched layer 17 made of a large number of fibers is stretched once, a large number of pleats are produced, and it is bulky and feels good. Therefore, it can be said that such a fiber layer is extremely preferable. In addition, since the elastic layer 16 tends to be rubber-like and some mask wearers do not like such a touch, it is preferable that the elastic layer 16 be on the outside in this sense.
[0012]
FIG. 3 is a view similar to FIG. 2 showing an example of the ear hook 3. The ear hook 3 shown in this figure is formed of a three-layer elastically stretchable composite sheet, and has stretch layers 17 on both sides of the elastic layer 16. When a part of the ear hook 3 extends in the front-rear direction between the mouth and the ear, the elastic layer 16 elastically expands and the expansion layer 17 expands inelastically. When the elongation is released, the elastic layer 16 returns elastically to its original size, and the stretched layer 17 shrinks to the same length as the elastic layer 16 while generating many pleats in the stretched portion. Such an ear hook 3 operates in the same manner as that of FIGS.
[0013]
FIG. 4 is a plan view of the mask 1 in a mode different from that in FIG. In this mask 1, the cover portion 2 and the ear hook portion 3 are formed in series by one elastically stretchable composite sheet used for the ear hook portion 3 in FIG. 2 or FIG. 3. The mask 1 is also worn after partially extending the ear hook 3 in the front-rear direction (left-right direction in the figure). The mask 1 of FIG. 4 is easy to manufacture and has a good wearing feeling, and is suitable as a disposable one.
[0014]
In this invention, the elastic layer 16 of an elastically stretchable composite sheet for forming at least the ear hook 3 of the mask 1 is a nonwoven fabric or woven fabric using elastic yarn made of an elastomer of thermoplastic synthetic resin, for example, urethane. In addition to forming with a cloth, an amorphous fiber web, etc., it can also be formed with an elastic stretchable film. The elastic layer 16 is preferably elastically stretchable at least 30% in one direction, more preferably at least 100%, and even more preferably 200%. The other stretched layer 17 is made of a non-elastically stretchable yarn made of a thermoplastic synthetic resin such as polyethylene or polypropylene. Such yarn is bonded to the elastic layer 16 in the form of a nonwoven fabric, a woven fabric, an irregular fiber web, or the like. The stretch layer 17 preferably has a breaking elongation of at least 70%, and can stretch to the same extent as or more than the limit at which the elastic layer 16 can elastically stretch. Specific examples of the stretch layer 17 are nonwoven fabrics, ethylene-propylene copolymers, and ethylene-propylene-butene copolymers having a basis weight of 20 to 200 g / m 2 formed by welding unstretched or low-stretched polypropylene continuous fibers to each other. Nonwoven fabrics having a basis weight of 20 to 200 g / m 2 formed by welding continuous fibers such as the above can be mentioned.
[0015]
【The invention's effect】
Since the mask according to the present invention can easily extend and contract only a part of the ear hook, the mask wearer can adjust the tension of the ear hook by setting the range of the part wide or narrow in advance. You can adjust it to suit you. If the part that is easily stretchable is set so that it is located between the mouth and the ear, the ear hook does not expand and contract at the base of the mask wearer's ear shell, and the mask has a comfortable wearing feeling. Become.
