Description
本発明は、既着の防護服を被覆するカバー体において、袖口部の過開口を抑制することができて密閉性が良く、防護服の汚染を軽減することができ、しかも、簡素な工程で低コストで製造することができる防護服カバーの袖口構造に関するものである。 The present invention relates to a cuff structure for a protective clothing cover that can prevent excessive opening of the cuffs, provides good sealing, reduces contamination of the protective clothing, and can be manufactured at low cost using simple processes in a cover body that covers already worn protective clothing.
感染症の診療においては、医療従事者への感染を防止するために、防護服を着用する必要があり、衛生上の理由から、使用後の防護服は、表面にウイルスが付着しているおそれがあるため、表面から飛散しないように密閉して速やかに廃棄する必要がある。 When treating infectious diseases, medical staff must wear protective clothing to prevent infection, and for hygiene reasons, protective clothing must be sealed after use to prevent viruses from scattering from the surface, and must be promptly disposed of.
ところで、近年では、新型かつ感染力の強いウイルスの感染者の爆発的増加が発生しており、医療現場における使い切りの衛生用資材の不足が深刻であり、本来であれば、廃棄しなければならないにもかかわらず、洗浄殺菌して再使用せざるを得ない状況になっている。 Incidentally, in recent years, there has been an explosive increase in the number of people infected with new, highly contagious viruses, which has led to a serious shortage of disposable sanitary supplies in medical settings, forcing medical facilities to clean, sterilize, and reuse supplies that would otherwise need to be discarded.
かかる事情から、既着の防護服に対して、簡易的なカバー体を更に被覆することができれば、このカバー体を交換することによって防護服の消費量を軽減することができると考えられる。 In light of these circumstances, if a simple cover body could be fitted over the protective clothing already worn, it would be possible to reduce the amount of protective clothing consumed by replacing this cover body.
しかしながら、かかる簡易的なカバー体の場合、大量生産によるコストダウンの観点から着用者の体格に合わせて複数のサイズを製造することが困難であることから、少し大きめのサイズを着用せざるを得ない場合が多く、特に、袖口部が大きく開口していることにより、作業中に袖がたくし上がってしまったり、あるいは、袖口部からウイルス等が侵入してしまうおそれがある。 However, with such simple coverings, it is difficult to manufacture multiple sizes to suit the wearer's physique, due to the need to reduce costs through mass production, so people often have no choice but to wear a slightly larger size. In particular, because the cuffs are wide open, there is a risk that the sleeves will be rolled up during work, or that viruses and other pathogens may enter through the cuffs.
従来、袖口部の過開口やたくし上がりを抑制するためには、紐を設けて結んだり、ゴムのしぼりを設けるものが知られているが（例えば、特許文献１参照）、紐やゴムなどの別部材が必要となり、材料コストの増大や加工工程の複雑化という問題がある。 Conventionally, methods to prevent the cuffs from opening too much or being rolled up have been known to use strings to tie or elastic cuffs (see, for example, Patent Document 1), but these require separate parts such as strings and elastic, which increases material costs and complicates the processing process.
本発明は、従来技術に上記のような問題があったことに鑑みて為されたものであり、その目的とするところは、既着の防護服を被覆するカバーにおいて、袖口部の過開口を抑制することができて密閉性が良く、防護服の汚染を軽減することができ、しかも、簡素な工程で低コストで製造することができる防護服カバーの袖口構造を提供することにある。 The present invention was made in consideration of the above-mentioned problems with the conventional technology, and its purpose is to provide a cuff structure for a protective clothing cover that can prevent over-opening of the cuffs, provides good sealing, reduces contamination of the protective clothing, and can be manufactured at low cost using simple processes in a cover that covers already worn protective clothing.
本発明者が上記技術的課題を解決するために採用した手段を、添付図面を参照して説明すれば、次のとおりである。 The means adopted by the inventor to solve the above technical problem are as follows, with reference to the attached drawings.
即ち、本発明は、既着の防護服の上から被覆する使い捨てのカバー体において、
前面シート材と背面シート材とを対面して重畳して、首肩部と袖下部と脇部とを縁部に沿ってそれぞれ止着する一方、
袖口部において、前記前面シート材と背面シート材とを破断可能に接合した易破断部を形成して、手指を挿通して前記易破断部を破断することによって、袖口部の過開口を抑制可能にするという技術的手段を採用したことによって、防護服カバーの袖口構造を完成させた。
That is, the present invention provides a disposable cover body that is applied over an already worn protective suit,
The front sheet material and the back sheet material are overlapped facing each other, and the neck and shoulder parts, the underarm parts of the sleeves and the sides are fastened along the edges, respectively.
The cuff structure of the protective clothing cover has been completed by adopting a technical measure in which an easily breakable portion is formed in the cuff portion by breaking the easily breakable portion by inserting fingers through it, thereby making it possible to prevent the cuff portion from opening excessively.
また、本発明は、上記課題を解決するために、必要に応じて上記手段に加え、袖口部において、前面シート材および背面シート材同士を部分的に接合されてなる複数の点接合部を設けて形成して、
手指が袖口部に挿入されるとき、当該手指が少なくとも一部の点接合部に圧接して、この圧接部位の点接合部を破断可能にするという技術的手段を採用することもできる。
In order to solve the above problems, the present invention provides a sleeveless garment having a plurality of point-joined sections formed by partially joining the front sheet material and the back sheet material to each other in the cuffs, in addition to the above means as necessary,
A technical measure can also be adopted in which, when a finger is inserted into the cuff, the finger presses against at least a portion of the point-bonded portion, making the point-bonded portion at the pressure-bonded portion breakable.
また、本発明は、上記課題を解決するために、必要に応じて上記手段に加え、袖口部において、前面シート材および背面シート材の内側面には、所定幅の面着部をそれぞれ設けて、かつ、これら面着部同士を対面して密接状態で付着し、
手指が袖口部に挿入されるとき、手指が前記面着部同士の間に圧入されて、この圧入部位における面着部同士の付着を破断可能にするという技術的手段を採用することができる。
In order to solve the above problems, the present invention provides, in addition to the above means as necessary, a face-attaching portion having a predetermined width is provided on the inner surface of the front sheet material and the back sheet material at the cuff portion, and these face-attaching portions are attached to each other in a face-to-face and in close contact with each other,
A technical means can be employed in which, when the fingers are inserted into the cuff, the fingers are pressed between the face-attached parts, making it possible to break the adhesion between the face-attached parts at this press-fitting portion.
更にまた、本発明は、上記課題を解決するために、必要に応じて上記手段に加え、袖口部において、前面シート材および背面シート材の内側面には、当該各シート材よりも低密度の熱可塑性樹脂材料からなる所定幅の面着部をそれぞれ設け、かつ、これら面着部同士を対面して密接状態で付着し、
手指が袖口部に挿入されるとき、手指が前記面着部同士の間に圧入されて、この圧入部位における面着部同士の付着を破断可能にするという技術的手段を採用することもできる。
Furthermore, in order to solve the above-mentioned problems, the present invention provides, in addition to the above-mentioned means as necessary, a facing portion of a predetermined width made of a thermoplastic resin material having a lower density than each of the front sheet material and the back sheet material is provided on the inner surface of each of the front sheet material and the back sheet material in the cuff portion, and these facing portions are adhered to each other in a face-to-face and intimate contact with each other,
It is also possible to employ a technical measure in which, when the fingers are inserted into the cuff, the fingers are pressed between the face-attached parts, making it possible to break the adhesion between the face-attached parts at this press-fitting portion.
更にまた、本発明は、上記課題を解決するために、必要に応じて上記手段に加え、袖口部において、前面シート材および背面シート材の内側面に接着剤を塗布して、破断可能な易破断部を設けて形成して、
手指が袖口部に挿入されるとき、当該手指が少なくとも一部の易破断部に圧接して、この圧接部位の易破断部を破断可能にするという技術的手段を採用することもできる。
Furthermore, in order to solve the above problems, the present invention provides a sleeve cuff portion having an easily breakable portion formed by applying an adhesive to the inner surface of the front sheet material and the back sheet material, in addition to the above means as necessary,
A technical measure can also be adopted in which, when a finger is inserted into the cuff, the finger presses against at least a part of the frangible portion, making the frangible portion at the pressed portion frangible.
本発明は、既着の防護服の上から被覆する使い捨てのカバー体において、前面シート材と背面シート材とを対面して重畳して、首肩部と袖下部と脇部とを縁部に沿ってそれぞれ止着する一方、袖口部において、前記前面シート材と背面シート材とを破断可能に接合した易破断部を形成したことにより、手指を挿通して前記易破断部を破断することによって、袖口部の過開口を抑制することができる。 The present invention provides a disposable covering body that is worn over protective clothing that has been previously worn. The front sheet material and the back sheet material are overlapped face-to-face and attached along the edges at the neck and shoulders, underarms, and underarms, while the front sheet material and the back sheet material are joined in a breakable manner at the cuffs to form an easily breakable section. By inserting a finger through the easily breakable section and breaking it, excessive opening of the cuffs can be prevented.
したがって、本発明の防護服カバーの袖口構造によれば、袖口部の過開口およびたくし上がりを抑制することができて密閉性が良く、袖口部からのウイルス等の侵入を防止して防護服の汚染を軽減することができる。 Therefore, the cuff structure of the protective clothing cover of the present invention can prevent the cuffs from opening too much or rolling up, providing good sealing, preventing the intrusion of viruses and other pathogens through the cuffs and reducing contamination of the protective clothing.
また、袖口を止めるための紐やゴムなどの別部材の用意や取付加工も不要で、ヒートプレス加工等でできるため、簡素な工程で低コストで製造することができることから、産業上の利用価値は頗る大きいといえる。 In addition, there is no need to prepare or attach separate parts such as strings or rubber bands to secure the cuffs, and since this can be done using heat press processing or other techniques, it can be manufactured at low cost using a simple process, making it of great industrial value.
『第１実施形態』
本発明の第１実施形態を図１から図８に基づいて説明する。図１中、符号１で指示するものはカバー体であり、符号２で指示するものは袖口部である。また、符号３で指示するものは止着部、符号４で指示するものは首肩部、符号５で指示するものは袖下部、符号６で指示するものは脇部である。
"First embodiment"
A first embodiment of the present invention will be described with reference to Fig. 1 to Fig. 8. In Fig. 1, reference numeral 1 indicates a cover body, reference numeral 2 indicates a cuff portion, reference numeral 3 indicates a fastening portion, reference numeral 4 indicates a neck/shoulder portion, reference numeral 5 indicates an underarm portion, and reference numeral 6 indicates an armpit portion.
本発明は、既着の防護服の上から被覆する使い捨てのカバー体１における袖口構造であって、構成するにあっては、まず、前面シート材１１と背面シート材１２と（共に単層）を対面して重畳して、首肩部４と袖下部５と脇部６とを縁部に沿ってそれぞれ止着する（図１および図２参照）。首肩部４の首出し孔は、予め切開して形成しても良いし、ミシン目で開口させるものでも良い。 The present invention is a cuff structure for a disposable cover body 1 that is fitted over already worn protective clothing. In constructing the cover body, first, the front sheet material 11 and the back sheet material 12 (both single layers) are overlapped facing each other, and the neck/shoulder area 4, underarm area 5, and armpit area 6 are attached along their edges (see Figures 1 and 2). The neck opening in the neck/shoulder area 4 may be formed by cutting in advance, or may be opened by perforations.
本実施形態では、成形性が良いことから、前面シート材１１および背面シート材１２の材料に熱可塑性樹脂材料を採用し、この熱可塑性樹脂材料として、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）などのポリオレフィン系樹脂、ポリエチレンテレフタレート（ＰＥＴ）、ナイロンなどを採用することができる。 In this embodiment, a thermoplastic resin material is used for the front sheet material 11 and the back sheet material 12 because of its good formability. As this thermoplastic resin material, polyolefin resins such as polyethylene (PE) and polypropylene (PP), polyethylene terephthalate (PET), nylon, etc. can be used.
また、前面シート材１１と背面シート材１２との止着方法（止着部３の構成）としては、熱融着によるサイドシールを行うことが好ましいが、接着剤等を使用することもできる。なお、首肩部４における両シート材の止着は、筒状の基材を使用することによって、辺を折り返して重ね合わせるだけで良く、成形上容易である。 The method of fastening the front sheet material 11 and the back sheet material 12 (the configuration of the fastening portion 3) is preferably a side seal by heat fusion, but adhesives or the like can also be used. The fastening of both sheet materials in the neck and shoulder portion 4 is easy to form, since a cylindrical base material is used and the sides can be simply folded and overlapped.
また、必要に応じて、前記背面シート材１２には上下に亙り切断可能なミシン目１２Ａを形成することができ、使用後の脱衣を容易にすることができる（図２参照）。本実施形態のミシン目１２Ａは、中央部に直線状のものを１本形成する。なお、必要に応じて、線の形状や本数、貫通部の間隔（ピッチ）などを適宜変更することもできる。例えば、上縁部近傍は着用者の頭部を挿通した後に、ミシン目の切断が必要以上に進行してしまうおそれがあるため、貫通部をやや広めの間隔にした切断しにくい部分を不規則的に設けることができる。 If necessary, the back sheet material 12 can be formed with cuttable perforations 12A extending from top to bottom, making it easier to remove the garment after use (see FIG. 2). In this embodiment, the perforation 12A is a single straight line formed in the center. If necessary, the shape and number of lines, the spacing (pitch) of the penetrations, etc. can be changed as appropriate. For example, near the upper edge, there is a risk that the perforations will cut further than necessary after the wearer's head is inserted, so it is possible to provide irregular sections where the penetrations are spaced slightly wider to make them harder to cut.
そして、袖口部２において、前記前面シート材１１と背面シート材１２とが破断可能に接合された易破断部２１を形成する。易破断とは、熱可塑性樹脂の熱溶融によって一体化した部分を分離するものであり、破壊して千切れるものや付着が剥がれる程度のものが含まれる。 Then, in the cuff portion 2, the front sheet material 11 and the back sheet material 12 are joined in a breakable manner to form an easily breakable portion 21. The term "easily breakable" refers to the separation of the integrated portion by thermal melting of the thermoplastic resin, and includes breakage and tearing, as well as peeling off of the adhesive.
本実施形態では、袖口部２において、易破断部２１を、前面シート材１１および背面シート材１２の内側面同士が部分的に接合されてなる複数の点接合部２１Ａを設けて形成する。 In this embodiment, the easily breakable portion 21 in the cuff portion 2 is formed by providing a plurality of point joints 21A in which the inner surfaces of the front sheet material 11 and the back sheet material 12 are partially joined together.
点接合部２１Ａの形成方法としては、予め設計した配置の点接合部２１Ａの形状の押し型を成形し、袖口部２の表面の所要位置に押し型によりヒートプレスする。この際、前面シート材１１および背面シート材１２のシート基材の材料の融点など物性によって、押し型の加熱温度や圧接時間を適宜変更することによって破断強度を調節することができる。また、溶融箇所および面積を変化させることによっても、破断強度を調節することができる。破断強度が大きすぎると手指Ｈを圧接したときにうまく破断しなかったり、あるいは、シート基材そのものが必要以上に引きちぎれてしまい穴あきの原因となる一方、破断強度が小さすぎると意図しない位置の点接合部２１Ａまでもが破断して、十分な密閉ができないおそれがある。 The method of forming the point joints 21A is to form a stamping die in the shape of the point joints 21A in a pre-designed arrangement, and then heat press the stamping die into the required positions on the surface of the cuff 2. At this time, the breaking strength can be adjusted by appropriately changing the heating temperature of the stamping die and the pressing time depending on the physical properties such as the melting point of the sheet base material of the front sheet material 11 and the back sheet material 12. The breaking strength can also be adjusted by changing the melting point and area. If the breaking strength is too high, the sheet will not break properly when pressed against the finger H, or the sheet base material itself will tear more than necessary, causing holes, while if the breaking strength is too low, the point joints 21A will break in unintended positions, and sufficient sealing may not be achieved.
点接合部２１Ａが、適切な破断強度を得るためには、１か所あたり最大でも１ｃｍ２程度の領域に収まるものが好ましく、より好ましくは１ｍｍ２程度の領域に収まるものがよい。なお、点接合部２１Ａにおける「点」とは、部分的ないし断続的な形状を意味し、図３（ａ）に示すような線状のものや、その他の非点対称的な種々の形状も当然に含まれる。また、点接合部２１Ａは、図３（ｂ）に示すように、２本を並行して設けたものであっても良い。 In order for the point bond 21A to have an appropriate breaking strength, each point is preferably within an area of about 1 cm2 at most, and more preferably within an area of about 1 mm2. Note that the "point" in the point bond 21A means a partial or intermittent shape, and naturally includes a linear shape as shown in Figure 3(a) and various other asymmetrical shapes. Also, the point bond 21A may be two parallel lines as shown in Figure 3(b).
そして、図４に示すように、手指Ｈが袖口部２に挿入されるとき、当該手指Ｈが少なくとも一部の点接合部２１Ａに圧接して、この圧接部位の点接合部２１Ａを破断可能である（図５参照）。この際、手指Ｈはできるだけ小さく畳んだ状態にして袖口部２に挿入することによって余分な位置の点接合部２１Ａの破断を防ぎ、挿通後に手指Ｈを広げるようにするのが好ましい。 As shown in FIG. 4, when the fingers H are inserted into the cuff 2, the fingers H press against at least some of the joints 21A, and this can break the joints 21A at the pressed areas (see FIG. 5). At this time, it is preferable to insert the fingers H into the cuff 2 in a folded state as small as possible to prevent breakage of the joints 21A in unnecessary positions, and to allow the fingers H to spread out after insertion.
こうして手指Ｈの挿入時に圧接する点接合部２１Ａを次々と破断していき、最後には、残存した最端の点接合部２１Ａが、更なる手指Ｈないし腕の圧接による破断の進行を防止することから、袖部のたくし上がりを防止することができるのである（図６参照）。 In this way, the point joints 21A that are pressed against each other when the fingers H are inserted are broken one after another, and finally, the remaining endmost point joint 21A prevents the breakage from progressing due to further pressure from the fingers H or the arm, thereby preventing the sleeve from being rolled up (see Figure 6).
本実施形態では、図７に示すように、易破断部２１（本実施形態では点接合部２１Ａ）を形成する位置を適宜設計変更することができ、例えば、図７（ａ）に示すように上端近傍を除いて形成したり、図７（ｂ）に示すように中央部を除いて形成したりすることができ、この非形成位置に手指Ｈをガイドして易破断部２１をスムースに破断させることができる。 In this embodiment, as shown in FIG. 7, the position where the easily breakable portion 21 (in this embodiment, the point joint 21A) is formed can be appropriately modified in design. For example, it can be formed excluding the vicinity of the upper end as shown in FIG. 7(a), or excluding the center as shown in FIG. 7(b), and the finger H can be guided to this non-forming position to smoothly break the easily breakable portion 21.
更にまた、図８に示すように、袖口部２を先端にかけて逓減的に小さくしたデザインにすることもでき、ウイルス等の侵入リスクを軽減することができる。 Furthermore, as shown in Figure 8, the cuff 2 can be designed to be tapered toward the tip, reducing the risk of viruses and other pathogens entering the sleeve.
『第２実施形態』
本発明の第２実施形態を図９から図１１に基づいて説明する。本実施形態では、袖口部２において、前面シート材１１および背面シート材１２の内側面に、所定幅の面着部２１Ｂをそれぞれ設け、かつ、これら面着部２１Ｂ同士を対面して密接状態で付着した構成である。
Second Embodiment
A second embodiment of the present invention will be described with reference to Figures 9 to 11. In this embodiment, a face-attaching portion 21B of a predetermined width is provided on the inner surface of the front sheet material 11 and the back sheet material 12 in the cuff portion 2, and these face-attaching portions 21B are attached to each other in a face-to-face and in close contact with each other.
この面着部２１Ｂを構成するにあっては、前面シート材１１および背面シート材１２のシート基材を、融点の異なる熱可塑性樹脂材料を一体に積層して構成し、前面シート材１１および背面シート材１２の内側面に低融点の樹脂材料を配設することによって、前面シート材１１および背面シート材１２の低融点樹脂材料部のみを破断可能にすることができる。 To form this surface-attaching portion 21B, the sheet base material of the front sheet material 11 and the back sheet material 12 is formed by integrally laminating thermoplastic resin materials with different melting points, and a low-melting point resin material is disposed on the inner surfaces of the front sheet material 11 and the back sheet material 12, making it possible to make only the low-melting point resin material portions of the front sheet material 11 and the back sheet material 12 breakable.
具体的には、高融点樹脂材料として高密度ポリエチレン（ＨＤＰＥ：通常、軟化温度約１２０℃、融点約１４０～１６０℃）を採用する一方、低融点樹脂材料（面着部２１Ｂ）として低密度ポリエチレン（ＬＤＰＥ：通常、軟化温度８０～９０℃、融点１１０～１２０℃）を採用する。そして、高融点樹脂材料の融点と低融点樹脂材料の融点との間の温度で加工（ヒートプレスなど）することにより、低密度樹脂材料のみが溶融するように加熱温度を調整しながら加工することができる。 Specifically, high density polyethylene (HDPE: typically softening temperature of approximately 120°C, melting point of approximately 140-160°C) is used as the high melting point resin material, while low density polyethylene (LDPE: typically softening temperature of 80-90°C, melting point of 110-120°C) is used as the low melting point resin material (surface attachment portion 21B). Then, by processing (heat pressing, etc.) at a temperature between the melting points of the high melting point resin material and the low melting point resin material, processing can be performed while adjusting the heating temperature so that only the low density resin material melts.
なお、高融点樹脂材料と低融点樹脂材料との積層方法としては、公知のラミネート工法や接着剤による接着を採用することができる。 The high melting point resin material and the low melting point resin material can be laminated by known lamination techniques or by bonding with an adhesive.
このような前面シート材１１および背面シート材１２のシート基材の積層構造にした場合は、破断した際にシート材が貫通することを防止し、貫通（穴あき）によるカバー体の強度の低下やウイルスの侵入などを防止することができる。 When the sheet base material of the front sheet material 11 and the back sheet material 12 is laminated in this manner, it is possible to prevent the sheet material from being penetrated when broken, and to prevent a decrease in the strength of the cover body and the entry of viruses due to penetration (holes).
また、製造工程においても、高融点樹脂材料の融点と低融点樹脂材料の融点との間の温度で加工（ヒートプレスなど）することにより、低融点樹脂材料のみを溶融させることができるため、シート基材を損傷することなく面着部２１Ｂ（易破断部２１）を簡単かつ確実に成形することができる。 In addition, during the manufacturing process, by processing (such as by heat pressing) at a temperature between the melting points of the high-melting-point resin material and the low-melting-point resin material, only the low-melting-point resin material can be melted, so that the surface-attached portion 21B (easily broken portion 21) can be easily and reliably formed without damaging the sheet base material.
そして、図１０に示すように、手指Ｈが袖口部２に挿入されるとき、手指Ｈを前記面着部２１Ｂ同士の間に圧入し、この圧入部位における面着部２１Ｂ同士の付着を破断可能である（図１１参照）。 As shown in FIG. 10, when the fingers H are inserted into the cuff 2, the fingers H are pressed between the face-attached parts 21B, and the attachment between the face-attached parts 21B at this press-fitting site can be broken (see FIG. 11).
この際、手指Ｈはできるだけ小さく畳んだ状態にして袖口部２に挿入して面着部２１Ｂ同士の間に圧入することによって余分な位置の面着部２１Ｂの破断を防ぎ、挿通後に手指Ｈを広げるようにするのが好ましい。このようにして、手指Ｈを挿通して前記易破断部２１（面着部２１Ｂ）を破断することによって、袖口部２の過開口を抑制可能であり、通常、袖部内における腕は手指Ｈよりも太いために、それ以上は腕が易破断部２１を押し広げて入っていくことは困難であることから、およそ手首付近で固定することができ、結果的に袖部のたくし上がりを防止することができる（図１２参照）。 At this time, it is preferable to fold the fingers H as small as possible before inserting them into the cuff 2 and pressing them between the face-attaching parts 21B to prevent breakage of the face-attaching parts 21B in unnecessary positions, and to spread the fingers H after insertion. In this way, by inserting the fingers H and breaking the easily breakable parts 21 (face-attaching parts 21B), it is possible to prevent the cuff 2 from opening too much, and since the arm inside the sleeve is usually thicker than the fingers H, it is difficult for the arm to push the easily breakable parts 21 open any further and enter, so it is possible to fix the fingers H approximately near the wrist, which results in preventing the sleeve from being rolled up (see Figure 12).
本発明は、概ね上記のように構成されるが、図示の実施形態に限定されるものでは決してなく、「特許請求の範囲」の記載内において種々の変更が可能であって、例えば、易破断部２１は、袖口部２において、前面シート材１１および背面シート材１２の内側面に接着剤（好ましくは、弱粘着性の接着剤）を塗布して設けることもでき、本発明の技術的範囲に属する。 The present invention is generally configured as described above, but is in no way limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the easily breakable portion 21 can be provided by applying an adhesive (preferably a weakly adhesive adhesive) to the inner surface of the front sheet material 11 and the back sheet material 12 in the cuff portion 2, and falls within the technical scope of the present invention.
