通気ラベルVentilation label 関連出願の相互参照Cross-reference of related applications
　本願は、日本国特願２０１４－３３０４３号の優先権を主張し、引用によって本願明細書の記載に組み込まれる。 This application claims the priority of Japanese Patent Application No. 2014-33043, and is incorporated herein by reference.
　本発明は、画定（換言すれば、閉塞）された内部空間を形成する被着体に貼り付け可能に構成されたラベルであって、被着体を介して内部空間と隣接する外部空間と内部空間との間で気体の流通を可能にする通気ラベルに関する。 The present invention is a label configured to be able to be attached to an adherend forming a delimited (in other words, closed) internal space, the external space adjacent to the internal space via the adherend and the internal The present invention relates to a ventilation label that enables gas to flow between spaces.
　従来、例えば、軟質包装材で画定（換言すれば、閉塞）された内部空間に物品が収容されてなる包装体においては、収容される物品の性質によって、包装体の内側の空間（内部空間）と外側の空間（外部空間）との間に気圧差が生じる場合がある。例えば、コーヒー豆や味噌等の物品が収容される場合、斯かる物品の発酵等の影響によって炭酸ガスが内部空間に発生する。このため、内部空間の気圧が外部空間よりも高くなる場合がある。また、焙煎されたコーヒー豆等の加熱された物品が収容される場合、斯かる物品の温度低下に伴って、内部空間の温度も低下することになる。このため、内部空間の気圧が外部空間よりも低くなる場合がある。 Conventionally, for example, in a packaging body in which an article is accommodated in an internal space defined (in other words, closed) by a soft packaging material, the space (internal space) inside the packaging body depends on the nature of the accommodated article. There may be a pressure difference between the outer space and the outer space (external space). For example, when an article such as coffee beans or miso is accommodated, carbon dioxide gas is generated in the internal space due to the influence of fermentation of the article. For this reason, the atmospheric pressure in the internal space may be higher than in the external space. In addition, when a heated article such as roasted coffee beans is accommodated, the temperature of the internal space also decreases as the temperature of the article decreases. For this reason, the atmospheric pressure in the internal space may be lower than in the external space.
　上述のように、内部空間と外部空間との間に気圧差が生じると、包装体が膨張して破裂したり、包装体が萎んで軟質包装材にシワや凹凸が生じ、意匠性が低下したりする場合がある。このため、内部空間と外部空間との間に生じた気圧差を解消する方法として、包装体を構成する軟質包装材に貫通孔を形成し、該貫通孔を覆うように通気性を有するラベルを貼り付ける方法が提案されている。 As described above, when a pressure difference occurs between the internal space and the external space, the packaging body expands and ruptures, or the packaging body wrinkles and wrinkles and irregularities occur in the soft packaging material, resulting in poor design. Sometimes. For this reason, as a method of eliminating the pressure difference generated between the internal space and the external space, a label having air permeability so as to cover the through hole is formed by forming a through hole in the soft packaging material constituting the package. A method of pasting has been proposed.
　斯かるラベルとしては、例えば、可撓制を有するフィルム片にスリットが形成されてなるラベルが知られている（特許文献１参照）。斯かるラベルは、軟質包装材に形成された貫通孔を覆うように軟質包装材に貼り付けられる際に、貫通孔とスリットとが重ならないようにすることで、貫通孔とスリットとが離間した状態になる。これにより、外部空間から内部空間への異物の侵入を防止することができると共に、内部空間の気体をスリットから外部空間へ排出することが可能となっている。 As such a label, for example, a label in which a slit is formed in a flexible film piece is known (see Patent Document 1). When such a label is attached to a soft packaging material so as to cover the through-hole formed in the soft packaging material, the through-hole and the slit are separated from each other by preventing the through-hole and the slit from overlapping each other. It becomes a state. As a result, it is possible to prevent foreign substances from entering the internal space from the external space, and to discharge the gas in the internal space from the slit to the external space.
　また、他のラベルとしては、通気孔を設けたシート状の基材フィルムと、該基材フィルムに積層される弁フィルムとの間に気体の流路が形成されるものが知られている（特許文献２参照）。斯かるラベルでは、基材フィルムと弁フィルムとの間の流路となる領域にシリコンオイルが充填されている。そして、基材フィルムの通気孔が軟質包装材の貫通孔と重なるように斯かるラベルが軟質包装材に貼り付けられることで、内部空間の気体が貫通孔および通気孔を通じてシリコンオイル内に入り込み、斯かる気体がシリコンオイル内を移動してラベルの端縁に達することで、内部空間の気体を外部空間へ排出することが可能となっている。 Other labels are known in which a gas flow path is formed between a sheet-like base film provided with air holes and a valve film laminated on the base film ( Patent Document 2). In such a label, silicon oil is filled in a region serving as a flow path between the base film and the valve film. And, such a label is affixed to the soft packaging material so that the vent hole of the base film overlaps the through hole of the soft packaging material, so that the gas in the internal space enters the silicon oil through the through hole and the vent hole, Such gas moves in the silicon oil and reaches the edge of the label, so that the gas in the internal space can be discharged to the external space.
　しかしながら、特許文献１に開示されたラベルは、軟質包装材の貫通孔から離間した位置にスリットが配置されるものの、スリットと貫通孔とが連通した状態になり易く、外部空間から内部空間への異物の混入を効果的に防止することができない。また、特許文献２に開示されたラベルは、気体の流路がシリコンオイルで充填されているため、流路を通じて外部空間から内部空間へ異物が侵入し難く、また、密閉性に優れている。しかしながら、シリコンオイルがラベルから流出し易いため、内部空間の密閉性を長期に亘って維持することができないだけでなく、流出したシリコンオイルが内部空間に侵入して内部空間に収容された物品を汚染する虞がある。 However, in the label disclosed in Patent Document 1, although the slit is disposed at a position separated from the through hole of the soft packaging material, the slit and the through hole are likely to be in communication with each other, and the external space to the internal space It is not possible to prevent foreign matters from being mixed effectively. Further, the label disclosed in Patent Document 2 has a gas flow path filled with silicon oil, so that it is difficult for foreign matter to enter from the external space to the internal space through the flow path, and has excellent sealing properties. However, since the silicone oil tends to flow out of the label, not only cannot the sealing of the internal space be maintained for a long period of time, but also the articles in which the leaked silicone oil has entered the internal space and are contained in the internal space. There is a risk of contamination.

It is an issue to provide.
　本発明に係る通気ラベルは、画定された内部空間を形成する被着体に形成された貫通孔を閉塞するように被着体に貼り付け可能に構成され、内部空間と該内部空間に被着体を介して隣接する外部空間との間で気体の通気を可能にする通気ラベルであって、自己吸着性を有する素材を用いて形成された自己吸着層を備えると共に、該自己吸着層を備える領域に面方向に線状に形成されて該領域を貫通する線状貫通部を備える。 The ventilation label according to the present invention is configured to be attached to an adherend so as to close a through-hole formed in the adherend forming a defined internal space, and is attached to the internal space and the internal space. A ventilation label that allows gas to flow between adjacent external spaces through a body, and includes a self-adsorption layer formed using a self-adsorbing material and the self-adsorption layer.

＜第一実施形態＞
　以下、本発明の第一実施形態について図１（ａ）～図３（ｂ）を参照しながら説明する。なお、以下の図面において同一または相当する部分には同一の参照符号を付しその説明は繰り返さない。 <First embodiment>
A first embodiment of the present invention will be described below with reference to FIGS. 1 (a) to 3 (b). In the following drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof will not be repeated.
　本実施形態に係る通気ラベル１は、図１（ａ）に示すように、軟質包装材を用いて構成されて、画定（換言すれば、閉塞）された（換言すれば、区画された）内部空間を形成する被着体Ａに貼り付けられるものである。本実施形態では、被着体Ａとして、軟質包装材を用いて物品が包装されてなる包装体Ａが使用される。該包装体Ａは、内部空間と連通する貫通孔Ａ１を備え、該貫通孔Ａ１を覆うように通気ラベル１（具体的には、後述する低剥離領域３）が貼り付けられる。そして、通気ラベル１は、内部空間の気圧（以下、内圧とも記す）と該内部空間に包装体Ａを介して隣接する外部空間の気圧（以下、外圧とも記す）との差が所定の範囲を超えた場合に、内部空間と外部空間との間で気体を通気させるように構成される。 As shown in FIG. 1A, the air-permeable label 1 according to the present embodiment is configured using a soft packaging material and is defined (in other words, closed) (in other words, partitioned). It is affixed to the adherend A that forms a space. In the present embodiment, as the adherend A, a package A in which an article is packaged using a soft packaging material is used. The package A includes a through hole A1 that communicates with the internal space, and a ventilation label 1 (specifically, a low peeling region 3 described later) is attached so as to cover the through hole A1. The ventilation label 1 has a predetermined range in which the difference between the atmospheric pressure of the internal space (hereinafter also referred to as internal pressure) and the atmospheric pressure of the external space adjacent to the internal space via the package A (hereinafter also referred to as external pressure). When exceeding, it is comprised so that gas may be ventilated between internal space and external space.
　通気ラベル１は、包装体Ａに対して貼り付けられる貼付領域２と、該貼付領域２よりも被着体に対する剥離強度が低い低剥離領域３とを備える。貼付領域２は、通気ラベル１の外周に沿って環状（具体的には、連続した環状）に形成され、通気ラベル１の周端部に形成される。一方、低剥離領域３は、環状の貼付領域２の内側に形成される。そして、低剥離領域３が貫通孔Ａ１を覆うように、通気ラベル１が包装体Ａに貼り付けられることで、低剥離領域３が貫通孔Ａ１を密閉すると共に、貼付領域２によって包装体Ａに対する通気ラベル１の貼り付け状態が維持される。また、通気ラベル１は、低剥離領域３に面方向に線状に形成されて該領域を貫通する線状貫通部１ａを更に備える。本実施形態では、線状貫通部１ａは、通気ラベル１が十字状に切り込まれて形成される。 The ventilation label 1 includes a sticking area 2 to be attached to the package A and a low peeling area 3 having a lower peel strength with respect to the adherend than the sticking area 2. The affixing region 2 is formed in an annular shape (specifically, a continuous annular shape) along the outer periphery of the ventilation label 1 and is formed at the peripheral end of the ventilation label 1. On the other hand, the low peeling region 3 is formed inside the annular pasting region 2. And since the ventilation label 1 is affixed on the package A so that the low peeling area 3 covers the through-hole A1, the low peeling area 3 seals the through-hole A1, and the sticking area 2 prevents the low-peeling area 3 from covering the package A. The affixed state of the ventilation label 1 is maintained. The ventilation label 1 further includes a linear through portion 1a that is formed in a line shape in the surface direction in the low peeling region 3 and penetrates the region. In this embodiment, the linear penetration part 1a is formed by cutting the ventilation label 1 into a cross shape.
　上記のような通気ラベル１は、図１（ｂ）に示すように、変形自在な本体層４と、粘着剤を用いて形成される粘着層５と、自己吸着性を有する素材を用いて形成される自己吸着層６とを備える。本実施形態では、自己吸着層６は、包装体Ａに対する剥離強度が粘着層５よりも低くなるように構成されると共に、粘着層５よりも面積が狭くなるように形成される。そして、本体層４と自己吸着層６との間に粘着層５が位置するように各層が積層されて通気ラベル１が構成される。これにより、本体層４と粘着層５と自己吸着層６とが積層された領域によって低剥離領域３が形成され、該低剥離領域３の周囲に本体層４と粘着層５とが積層された領域によって貼付領域２が形成される。 The air-permeable label 1 as described above is formed using a deformable main body layer 4, an adhesive layer 5 formed using an adhesive, and a self-adsorbing material, as shown in FIG. The self-adsorption layer 6 is provided. In the present embodiment, the self-adsorption layer 6 is formed so that the peel strength with respect to the package A is lower than that of the adhesive layer 5 and the area is narrower than that of the adhesive layer 5. And each layer is laminated | stacked so that the adhesion layer 5 may be located between the main body layer 4 and the self-adsorption layer 6, and the ventilation label 1 is comprised. Thereby, the low peeling area 3 was formed by the area where the main body layer 4, the adhesive layer 5, and the self-adsorption layer 6 were laminated, and the main body layer 4 and the adhesive layer 5 were laminated around the low peeling area 3. The pasting area 2 is formed by the area.
　本体層４は、変形自在な樹脂フィルムを用いて形成される。例えば、包装体Ａを構成する軟質包装材と同等の柔軟性を有する樹脂フィルムを用いることが可能である。本体層４を構成する素材や本体層４の厚みとしては、特に限定されるものではなく、後述する線状貫通部１ａを開口させる際の内圧と外圧との差に応じて適宜選択することが好ましい。具体的には、樹脂フィルムを構成する素材としては、例えば、ポリエチレンテレフタレート、ポリプロピレン等が挙げられる。樹脂フィルムの厚みとしては、例えば、１２μｍ以上２００μｍ以下であってもよく、１６μｍ以上７５μｍ以下であってもよい。 The main body layer 4 is formed using a deformable resin film. For example, it is possible to use a resin film having the same flexibility as the soft packaging material constituting the package A. The material constituting the main body layer 4 and the thickness of the main body layer 4 are not particularly limited, and may be appropriately selected according to the difference between the internal pressure and the external pressure when the linear through-hole 1a described later is opened. preferable. Specifically, examples of the material constituting the resin film include polyethylene terephthalate and polypropylene. The thickness of the resin film may be, for example, 12 μm or more and 200 μm or less, or 16 μm or more and 75 μm or less.
　粘着層５は、本体層４の一方の面に粘着剤が塗工されて形成される。そして、粘着層５の一方の面に自己吸着層６が積層されることで、粘着層５には、自己吸着層６によって被覆された領域と、該領域以外であって粘着層５が露出した領域とが形成される。これにより、通気ラベル１には、自己吸着層６と粘着層５とが積層された領域（換言すれば、自己吸着層６で粘着層５が被覆された領域）によって低剥離領域３が形成され、粘着層５における自己吸着層６が積層されていない領域（換言すれば、粘着層５が露出した領域）によって貼付領域２が形成される。 The adhesive layer 5 is formed by applying an adhesive to one surface of the main body layer 4. Then, by laminating the self-adsorption layer 6 on one surface of the adhesive layer 5, the adhesive layer 5 is exposed to the area covered by the self-adsorption layer 6 and the adhesive layer 5 other than the area. A region is formed. As a result, the low-peeling region 3 is formed on the ventilation label 1 by the region where the self-adsorption layer 6 and the adhesive layer 5 are laminated (in other words, the region where the adhesive layer 5 is covered with the self-adsorption layer 6). The pasting region 2 is formed by a region of the adhesive layer 5 where the self-adsorption layer 6 is not laminated (in other words, a region where the adhesive layer 5 is exposed).
　粘着層５を構成する素材や粘着層５の厚みとしては、特に限定されるものではなく、後述する線状貫通部１ａを開口させる際の内圧と外圧との差に応じて適宜選択することが好ましい。粘着層５を構成する粘着剤としては、粘着層５の包装体Ａに対する剥離強度が自己吸着層６よりも高くなれば、特に限定されるものではなく、例えば、アクリル酸ブチルホモポリマー又はコポリマー、アクリル酸２エチルヘキシルホモポリマー又はコポリマー、天然ゴム等から構成されるものが挙げられる。粘着層５の厚みとしては、特に限定されるものではなく、例えば、１０μｍ以上５０μｍ以下であってもよく、１５μｍ以上２５μｍ以下であってもよい。粘着層５の包装体Ａに対する剥離強度（即ち、貼付領域２の剥離強度）としては、特に限定されるものではなく、例えば、２００Ｎ／ｍ以上１２００Ｎ／ｍ以下であってもよく、４００Ｎ／ｍ以上８００Ｎ／ｍ以下であってもよい。 It does not specifically limit as the raw material which comprises the adhesion layer 5, or the thickness of the adhesion layer 5, It can select suitably according to the difference of the internal pressure at the time of opening the linear penetration part 1a mentioned later and an external pressure. preferable. The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 5 is not particularly limited as long as the peel strength of the pressure-sensitive adhesive layer 5 with respect to the package A is higher than that of the self-adsorption layer 6. For example, butyl acrylate homopolymer or copolymer, Examples include those composed of 2-ethylhexyl acrylate homopolymer or copolymer, natural rubber and the like. The thickness of the adhesive layer 5 is not particularly limited, and may be, for example, 10 μm or more and 50 μm or less, or 15 μm or more and 25 μm or less. The peel strength of the adhesive layer 5 with respect to the package A (that is, the peel strength of the pasting region 2) is not particularly limited, and may be, for example, 200 N / m or more and 1200 N / m or less, and 400 N / m. It may be 800 N / m or less.
　自己吸着層６は、粘着層５よりも面積が小さくなるように形成され、粘着層５の外周よりも内側の領域（具体的には、略中央部）に配置される。また、自己吸着層６の厚みとしては、特に限定されるものではなく、例えば、自己吸着性を有する樹脂を含有する塗料を粘着層５に印刷（好ましくは、フレキソ印刷）する方法で自己吸着層６を形成する場合には、１μｍ以上２０μｍ以下であってもよく、２μｍ以上１０μｍ以下であってもよく、６μｍ前後であってもよい。又は、自己吸着性を有する樹脂を粘着層５に滴下する方法で自己吸着層６を形成する場合には、５μｍ以上１０μｍ以下であってもよく、７μｍ以上９μｍ以下であってもよい。自己吸着層６を構成する樹脂としては、特に限定されるものではなく、例えば、シリコーン（メタ）アクリレート類の重合体、長鎖アルキルアクリレート重合体等が挙げられる。自己吸着層６の軟質包装材に対する剥離強度（即ち、低剥離領域３の剥離強度）としては、特に限定されるものではない。 The self-adsorption layer 6 is formed so as to have a smaller area than the adhesive layer 5, and is disposed in a region inside the outer periphery of the adhesive layer 5 (specifically, a substantially central portion). The thickness of the self-adsorption layer 6 is not particularly limited. For example, the self-adsorption layer may be printed by a method of printing (preferably flexographic printing) a paint containing a resin having self-adsorption properties on the adhesive layer 5. When 6 is formed, it may be 1 μm or more and 20 μm or less, may be 2 μm or more and 10 μm or less, and may be around 6 μm. Or when forming the self-adsorption layer 6 by the method of dripping the resin which has self-adsorption to the adhesion layer 5, 5 micrometers or more and 10 micrometers or less may be sufficient, and 7 micrometers or more and 9 micrometers or less may be sufficient. The resin constituting the self-adsorbing layer 6 is not particularly limited, and examples thereof include silicone (meth) acrylate polymers and long-chain alkyl acrylate polymers. The peel strength of the self-adsorbing layer 6 with respect to the soft packaging material (that is, the peel strength of the low peel region 3) is not particularly limited.
　また、通気ラベル１は、自己吸着層６を備える領域（具体的には、低剥離領域３）に面方向に線状に形成されて該領域を貫通する線状貫通部１ａを備える。つまり、線状貫通部１ａは、本体層４、粘着層５、および、自己吸着層６が厚み方向の対応する位置で部分的に切断されて形成される。そして、線状貫通部１ａでは、通気ラベル１における線状貫通部１ａを構成する対峙する端部（以下、通気ラベル対峙端部とも記す）１ｂ，１ｂ同士が当接した状態となる。 Further, the air-permeable label 1 includes a linear penetrating portion 1a that is linearly formed in a plane direction in a region including the self-adsorption layer 6 (specifically, the low peeling region 3) and penetrates the region. That is, the linear penetration part 1a is formed by partially cutting the main body layer 4, the adhesive layer 5, and the self-adsorption layer 6 at corresponding positions in the thickness direction. And in the linear penetration part 1a, the edge parts (henceforth ventilation label opposite edge part) 1b and 1b which comprise the linear penetration part 1a in the ventilation | gas_flowing label 1 will be in the state which contact | abutted.
　具体的には、通気ラベル対峙端部１ｂ，１ｂ同士が当接した状態では、本体層４の対峙する端部（以下、本体層対峙端部とも記す）４ａ，４ａ同士と、粘着層５の対峙する端部（以下、粘着層対峙端部とも記す）５ａ，５ａ同士と、自己吸着層６の対峙する端部（以下、自己吸着層対峙端部とも記す）６ａ，６ａ同士とがそれぞれ当接した状態となる。斯かる状態では、粘着層対峙端部５ａ，５ａ同士は、自身の粘着力によって粘着した状態となり、自己吸着層対峙端部６ａ，６ａ同士は、自身の吸着力で吸着した状態となる。 Specifically, in a state where the air-flowing label opposite end portions 1b and 1b are in contact with each other, the opposite end portions (hereinafter also referred to as main body layer opposite end portions) 4a and 4a of the main body layer 4 and the adhesive layer 5 The opposite ends (hereinafter also referred to as adhesive layer opposite ends) 5a, 5a and the opposite ends (hereinafter also referred to as self-adsorbing layer opposite ends) 6a, 6a of the self-adsorbing layer 6 correspond to each other. It will be in contact. In such a state, the adhesive layer opposite end portions 5a, 5a are in a state of being adhered by their own adhesive force, and the self adsorbing layer opposite end portions 6a, 6a are in an adsorbed state by their own attractive force.
　そして、通気ラベル対峙端部１ｂ，１ｂに対して、通気ラベル１の一方の面側又は他方の面側に向かって所定の力（具体的には、気圧）が加わった際に、通気ラベル対峙端部１ｂ，１ｂは、通気ラベル１の一方の面側又は他方の面側へ変位（弾性変形）可能に構成される。そして、通気ラベル対峙端部１ｂ，１ｂが通気ラベル１の一方の面側又は他方の面側へ変位（弾性変形）することで、通気ラベル対峙端部１ｂ，１ｂ同士の間に隙間が形成されるように構成される。 Then, when a predetermined force (specifically, atmospheric pressure) is applied toward the one side or the other side of the ventilation label 1 with respect to the ventilation label opposite ends 1b, 1b, The end portions 1b, 1b are configured to be displaceable (elastically deformable) to one surface side or the other surface side of the ventilation label 1. Then, the ventilation label opposite end portions 1b, 1b are displaced (elastically deformed) to one surface side or the other surface side of the ventilation label 1, whereby a gap is formed between the ventilation label opposite end portions 1b, 1b. Configured to be
　次に、上記のように構成される通気ラベル１の使用方法について説明する。図２（ａ）に示すように、通気ラベル１は、線状貫通部１ａが貫通孔Ａ１と重なるように包装体Ａに貼り付けられる。この際、低剥離領域３は、軟質包装材における貫通孔Ａ１の周辺領域に密着（具体的には、低剥離領域３を構成する自己吸着層６が貫通孔Ａ１の周辺領域に吸着）した状態となる。一方、貼付領域２（具体的には、粘着層５）は、包装体Ａにおける貫通孔Ａ１から離間した位置の環状の領域に貼り付いた状態となる。 Next, a method for using the ventilation label 1 configured as described above will be described. As shown in FIG. 2A, the ventilation label 1 is affixed to the package A so that the linear through portion 1a overlaps the through hole A1. At this time, the low peeling region 3 is in close contact with the peripheral region of the through hole A1 in the soft packaging material (specifically, the self-adsorption layer 6 constituting the low peeling region 3 is adsorbed on the peripheral region of the through hole A1). It becomes. On the other hand, the sticking region 2 (specifically, the adhesive layer 5) is in a state of sticking to an annular region at a position away from the through hole A1 in the package A.
　そして、通気ラベル１が包装体Ａに貼り付けられた状態で、内部空間Ｒ１の気圧（内圧）と、包装体Ａを介して内部空間Ｒ１に隣接する外部空間Ｒ２の気圧（外圧）との差が所定の範囲である場合には、貫通孔Ａ１が通気ラベル１によって密封された状態が維持される。具体的には、内圧と外圧との差が所定の範囲である場合には、線状貫通部１ａを構成する通気ラベル対峙端部１ｂ，１ｂ同士が当接した状態となる。斯かる状態では、自己吸着層対峙端部６ａ，６ａ同士が自身の吸着力によって吸着して密着した状態となり、線状貫通部１ａが密閉された状態となる。これにより、貫通孔Ａ１が通気ラベル１（具体的には、自己吸着層６）によって密封された状態が維持される。 And the difference between the atmospheric pressure (internal pressure) of the internal space R1 and the atmospheric pressure (external pressure) of the external space R2 adjacent to the internal space R1 through the packaging body A with the ventilation label 1 attached to the packaging body A Is within the predetermined range, the state in which the through-hole A1 is sealed with the ventilation label 1 is maintained. Specifically, when the difference between the internal pressure and the external pressure is within a predetermined range, the ventilation label opposite end portions 1b, 1b constituting the linear penetration portion 1a are in contact with each other. In such a state, the self-adsorbing layer opposite end portions 6a, 6a are adsorbed and adhered to each other by their own adsorbing force, and the linear penetrating portion 1a is sealed. Thereby, the state in which the through hole A1 is sealed by the ventilation label 1 (specifically, the self-adsorption layer 6) is maintained.
　上記のようにして包装体Ａに貼り付けられた通気ラベル１は、内圧と外圧との差が所定の範囲を超えた場合、内部空間Ｒ１と外部空間Ｒ２との間で気体の流通を可能にする。具体的には、内圧が外圧よりも高くなって内圧と外圧との差が所定の範囲を超えた場合には、図２（ｂ）に示すように、線状貫通部１ａを構成する通気ラベル対峙端部１ｂ，１ｂに内圧が加わって、通気ラベル対峙端部１ｂ，１ｂが外部空間Ｒ２側へ変位（弾性変形）して離間する。これにより、通気ラベル対峙端部１ｂ，１ｂ同士の間（本体層対峙端部４ａ，４ａ同士、粘着層対峙端部５ａ，５ａ同士、自己吸着層対峙端部６ａ，６ａ同士のそれぞれの間）に隙間が形成され、斯かる隙間を通じて内部空間Ｒ１の気体が外部空間Ｒ２へ排出される。 When the difference between the internal pressure and the external pressure exceeds a predetermined range, the ventilation label 1 attached to the package A as described above allows gas to flow between the internal space R1 and the external space R2. To do. Specifically, when the internal pressure is higher than the external pressure and the difference between the internal pressure and the external pressure exceeds a predetermined range, as shown in FIG. 2 (b), a ventilation label constituting the linear penetrating portion 1a. Internal pressure is applied to the opposite end portions 1b, 1b, and the ventilation label opposite end portions 1b, 1b are displaced (elastically deformed) toward the outer space R2 side to be separated. Thereby, between ventilation | gas_flowing label opposite edge part 1b, 1b (Between main body layer opposite edge part 4a, 4a, adhesive layer opposite edge part 5a, 5a, between each self-adsorption layer opposite edge part 6a, 6a) A gap is formed in the inner space R1, and the gas in the inner space R1 is discharged to the outer space R2 through the gap.
　上記とは逆に、外圧が内圧よりも高くなって内圧と外圧との差が所定の範囲を超えた場合には、図３（ａ）に示すように、線状貫通部１ａを構成する通気ラベル対峙端部１ｂ，１ｂに外圧が加わって、通気ラベル対峙端部１ｂ，１ｂが内部空間Ｒ１側へ変位（弾性変形）して離間する。これにより、通気ラベル対峙端部１ｂ，１ｂ同士の間に隙間が形成され、斯かる隙間を通じて外部空間Ｒ２の気体が内部空間Ｒ１へ流入する。 Contrary to the above, when the external pressure becomes higher than the internal pressure and the difference between the internal pressure and the external pressure exceeds a predetermined range, as shown in FIG. External pressure is applied to the label opposite end portions 1b, 1b, and the ventilation label opposite end portions 1b, 1b are displaced (elastically deformed) toward the inner space R1 and separated. Thereby, a clearance gap is formed between ventilation | gas_flowing label pair edge part 1b, 1b, and the gas of external space R2 flows in into internal space R1 through such clearance gap.
　そして、上述のように内部空間Ｒ１から外部空間Ｒ２への気体の排出や、外部空間Ｒ２から内部空間Ｒ１への気体の流入によって、内圧と外圧との差が所定の範囲になることで、図３（ｂ）に示すように、離間していた通気ラベル対峙端部１ｂ，１ｂ同士が当接する位置にまで変位（復帰）する。これにより、通気ラベル対峙端部１ｂ，１ｂ同士の間に形成されていた隙間が閉塞される。この際、自己吸着層対峙端部６ａ，６ａ同士は、自身の吸着力によって密着した状態となるため、貫通孔Ａ１が密封された状態に再度維持される。 Then, as described above, the difference between the internal pressure and the external pressure falls within a predetermined range due to the discharge of gas from the internal space R1 to the external space R2 and the inflow of gas from the external space R2 to the internal space R1. As shown in FIG. 3 (b), it is displaced (returned) to a position where the separated air-permeable label pair end portions 1b, 1b are in contact with each other. Thereby, the clearance gap formed between ventilation | gas_flowing label pair edge parts 1b and 1b is obstruct | occluded. At this time, the self-adsorbing layer opposite end portions 6a, 6a are brought into close contact with each other by their own adsorbing force, so that the through hole A1 is maintained again in a sealed state.
　以上のように、被着体Ａの貫通孔Ａ１を覆うように通気ラベル１が被着体Ａに貼り付けられることで、内部空間Ｒ１の密封状態を維持することができると共に、内圧が外圧よりも高い場合だけでなく、外圧が内圧よりも高い場合であっても、内部空間Ｒ１と外部空間Ｒ２との間で気体の流通を可能して、内部空間Ｒ１と外部空間Ｒ２との間の気圧差を解消することができる。また、内部空間Ｒ１への異物の混入を防止することができる。 As described above, the air-permeable label 1 is attached to the adherend A so as to cover the through hole A1 of the adherend A, so that the sealed state of the internal space R1 can be maintained and the internal pressure is higher than the external pressure. Even when the external pressure is higher than the internal pressure, the gas can flow between the internal space R1 and the external space R2, and the air pressure between the internal space R1 and the external space R2 The difference can be eliminated. Further, it is possible to prevent foreign matter from entering the internal space R1.
　即ち、通気ラベル１の線状貫通部１ａが被着体Ａの貫通孔Ａ１と重なるように、通気ラベル１が被着体Ａに貼り付けられることで、被着体Ａによって形成される内部空間Ｒ１と外部空間Ｒ２との間で気体の流通が可能になると共に、内部空間Ｒ１の密封状態を良好に維持することが可能となる。 That is, the inner space formed by the adherend A is obtained by attaching the vent label 1 to the adherend A so that the linear through portion 1a of the vent label 1 overlaps the through hole A1 of the adherend A. Gas can flow between R1 and the external space R2, and the sealed state of the internal space R1 can be well maintained.
　具体的には、線状貫通部１ａでは、線状貫通部１ａを構成する自己吸着層対峙端部６ａ，６ａ同士が当接した状態となる。この際、自己吸着層対峙端部６ａ，６ａ同士が互いに吸着することで、線状貫通部１ａが密閉された状態になる。これにより、内部空間Ｒ１の密封状態が維持される。 Specifically, in the linear penetration part 1a, the self-adsorption layer opposite end parts 6a, 6a constituting the linear penetration part 1a are in contact with each other. At this time, the self-adsorption layer opposite end portions 6a and 6a are adsorbed to each other, so that the linear penetration portion 1a is sealed. Thereby, the sealed state of the internal space R1 is maintained.
　そして、内圧が外圧よりも高くなった場合、内圧の作用によって、吸着していた自己吸着層対峙端部６ａ，６ａが外部空間Ｒ２側へ変位（弾性変形）して部分的又は全体的に離間した状態になる。これにより、自己吸着層対峙端部６ａ，６ａ同士の間に隙間が形成されて、斯かる隙間から内部空間Ｒ１の気体が外部空間Ｒ２へ排出される。逆に、外圧が内圧よりも高くなった場合、外圧の作用によって、吸着していた自己吸着層対峙端部６ａ，６ａが内部空間Ｒ１側へ変位（弾性変形）して部分的又は全体的に離間した状態になる。これにより、自己吸着層対峙端部６ａ，６ａ同士の間に隙間が形成されて、斯かる隙間から外部空間Ｒ２の気体が内部空間Ｒ１へ流入する。 When the internal pressure becomes higher than the external pressure, the adsorbed self-adsorptive layer opposite end portions 6a, 6a are displaced (elastically deformed) toward the external space R2 by the action of the internal pressure, and are partially or entirely separated. It will be in the state. Thereby, a gap is formed between the self-adsorbing layer pair end portions 6a, 6a, and the gas in the internal space R1 is discharged from the gap to the external space R2. On the contrary, when the external pressure becomes higher than the internal pressure, the adsorbed self-adsorption layer opposite end portions 6a, 6a are displaced (elastically deformed) toward the internal space R1 due to the action of the external pressure, and partially or entirely. It will be in a separated state. Thereby, a gap is formed between the self-adsorbing layer pair end portions 6a, 6a, and the gas in the external space R2 flows into the internal space R1 from the gap.
　以上のように、自己吸着層対峙端部６ａ，６ａ同士の間に形成される隙間を通じて、内部空間Ｒ１と外部空間Ｒ２との間で気体の流通が可能となることで、内圧と外圧との差を調整することができる。そして、内圧と外圧との差を調整された状態では、自己吸着層対峙端部６ａ，６ａ同士が吸着して隙間が消失することで、線状貫通部１ａが密閉された状態になる。これにより、内部空間Ｒ１の密封状態を、再度、維持することができ、外部空間Ｒ２からの異物の侵入を防止することができる。 As described above, gas can flow between the internal space R1 and the external space R2 through the gap formed between the self-adsorption layer opposite end portions 6a, 6a, so that the internal pressure and the external pressure can be reduced. The difference can be adjusted. In a state where the difference between the internal pressure and the external pressure is adjusted, the self-adsorbing layer opposite end portions 6a, 6a are adsorbed and the gap disappears, so that the linear penetration portion 1a is sealed. Thereby, the sealed state of the internal space R1 can be maintained again, and the entry of foreign matter from the external space R2 can be prevented.
　また、環状の貼付領域２の内側に低剥離領域３が形成されることで、通気ラベル１が被着体Ａに貼り付けられた状態で、低剥離領域３と被着体Ａとの間に、低剥離領域３の周囲から気体が流入することや、外部空間Ｒ２から異物が侵入することが防止される。このため、内部空間Ｒ１の密封状態を良好に維持することができる。また、低剥離領域３に線状貫通部１ａが形成されることで、線状貫通部１ａを構成する通気ラベル１の端部が被着体Ａから剥がれやすくなるため、自己吸着層対峙端部６ａ，６ａの変位（具体的には、自己吸着層対峙端部６ａ，６ａ同士が吸着した状態から部分的又は全体的に離間して隙間が形成されるまでの弾性変形）を阻害することがない。このため、内部空間Ｒ１と外部空間Ｒ２との間での気体の流通をより迅速に行うことができる。 In addition, since the low peeling area 3 is formed inside the annular sticking area 2, the air-permeable label 1 is attached to the adherend A between the low peel area 3 and the adherend A. Further, it is possible to prevent gas from flowing in from the periphery of the low peeling region 3 and foreign matter from entering from the external space R2. For this reason, the sealing state of internal space R1 can be maintained favorably. Moreover, since the edge part of the ventilation | gas_flowing label 1 which comprises the linear penetration part 1a becomes easy to peel from the to-be-adhered body A by forming the linear penetration part 1a in the low peeling area | region 3, a self-adsorption layer opposite edge part Inhibiting the displacement of 6a, 6a (specifically, elastic deformation until a gap is formed partially or entirely away from the state in which the self-adsorbing layer opposite end portions 6a, 6a are adsorbed to each other) Absent. For this reason, the gas can be circulated more quickly between the internal space R1 and the external space R2.
　また、自己吸着層６と粘着層５とが積層された領域に線状貫通部１ａが形成されることで、線状貫通部１ａを構成する粘着層対峙端部５ａ，５ａ同士が当接した状態となる。この際、粘着層対峙端部５ａ，５ａ同士は、自身の粘着力によって、粘着した状態となるため、斯かる粘着力によって自己吸着層対峙端部６ａ，６ａの変位（具体的には、自己吸着層対峙端部６ａ，６ａ同士が吸着した状態から部分的又は全体的に離間して隙間が形成されるまでの弾性変形）が制限される。これにより、自己吸着層対峙端部６ａ，６ａ同士の間に意図せずに隙間が形成されるのを防止することができる。 Moreover, the linear penetration part 1a is formed in the area | region where the self-adsorption layer 6 and the adhesion layer 5 were laminated | stacked, and the adhesion layer opposite edge parts 5a and 5a which comprise the linear penetration part 1a contact | abutted It becomes a state. At this time, since the adhesive layer opposite end portions 5a and 5a are in a state of being adhered by their own adhesive force, the displacement (specifically, self-adhesive layer opposite end portions 6a and 6a by the adhesive force) Elastic deformation until the gap is formed partially or entirely away from the state where the adsorbing layer opposite end portions 6a, 6a are adsorbed is limited. Thereby, it is possible to prevent a gap from being formed unintentionally between the self-adsorbing layer opposite end portions 6a, 6a.
＜第二実施形態＞
　次に、本発明の第二実施形態について、図４（ａ）を用いて説明する。第二実施形態に係る通気ラベル１０は、第一実施形態に係る通気ラベル１と比較すると、主に、線状貫通部１０ａの構成が異なるものである。これに伴い、粘着層５０の構成も一部異なる。従って、以下では、第一実施形態と異なる点を中心に説明し、同一の構成に対しては同一の符号を付すこととして説明を省略する。 <Second embodiment>
Next, a second embodiment of the present invention will be described with reference to FIG. The ventilation label 10 according to the second embodiment is mainly different from the ventilation label 1 according to the first embodiment in the configuration of the linear penetrating portion 10a. Accordingly, the configuration of the adhesive layer 50 is also partially different. Therefore, below, it demonstrates centering on a different point from 1st embodiment, and abbreviate | omits description by attaching | subjecting the same code | symbol to the same structure.
　通気ラベル１０は、粘着層５０が積層されていない領域に線状貫通部１０ａを備える。具体的には、通気ラベル１０では、本体層４の外周に沿って環状に形成された粘着層５０が本体層４の外周部に積層される。一方、自己吸着層６は、本体層４における粘着層５０が積層されていない領域（具体的には、環状の粘着層５０の内側の領域）に積層される。つまり、粘着層５０は、自己吸着層６の周囲を囲むように、且つ、自己吸着層６の周端部と接するように形成される。そして、本体層４および自己吸着層６が積層された領域（即ち、粘着層５０が積層されていない領域）に線状貫通部１０ａが形成される。 The ventilation label 10 includes a linear through portion 10a in a region where the adhesive layer 50 is not laminated. Specifically, in the ventilation label 10, an adhesive layer 50 formed in an annular shape along the outer periphery of the main body layer 4 is laminated on the outer peripheral portion of the main body layer 4. On the other hand, the self-adsorbing layer 6 is laminated in a region (specifically, a region inside the annular adhesive layer 50) in the main body layer 4 where the adhesive layer 50 is not laminated. That is, the adhesive layer 50 is formed so as to surround the self-adsorption layer 6 and to be in contact with the peripheral end portion of the self-adsorption layer 6. And the linear penetration part 10a is formed in the area | region (namely, area | region where the adhesion layer 50 is not laminated | stacked) where the main body layer 4 and the self-adsorption layer 6 were laminated | stacked.
　これにより、線状貫通部１０ａが粘着層５０を備えない領域に形成されることで、自己吸着層対峙端部６ａ，６ａの変位（具体的には、自己吸着層対峙端部６ａ，６ａ同士が吸着した状態から部分的又は全体的に離間して隙間が形成されるまでの弾性変形）が粘着層５０によって阻害されるのを防止することができる。 Thereby, the linear penetration part 10a is formed in the area | region which is not equipped with the adhesion layer 50, and the displacement (specifically, self-adsorption layer opposite edge part 6a, 6a is self-adsorption layer opposite edge part 6a, 6a) It is possible to prevent the adhesive layer 50 from inhibiting the elastic deformation until the gap is formed partially or entirely apart from the state where the material is adsorbed.
　具体的には、自己吸着層６と粘着層５０とが積層された領域に線状貫通部１０ａが形成された場合、線状貫通部１０ａを構成する粘着層５０の対峙する端部（以下、粘着層対峙端部とも記す）５ａ，５ａ同士が当接した状態となる。この際、粘着層対峙端部５ａ，５ａ同士は、自身の粘着力によって、粘着した状態となるため、斯かる粘着力によって自己吸着層対峙端部６ａ，６ａの変位（具体的には、自己吸着層対峙端部６ａ，６ａ同士が吸着した状態から部分的又は全体的に離間して隙間が形成されるまでの弾性変形）が制限される。 Specifically, when the linear penetration part 10a is formed in the region where the self-adsorption layer 6 and the adhesive layer 50 are laminated, the opposite ends (hereinafter referred to as the adhesive layer 50) constituting the linear penetration part 10a 5a, 5a are in contact with each other. At this time, since the adhesive layer opposite end portions 5a and 5a are in a state of being adhered by their own adhesive force, the displacement (specifically, self-adhesive layer opposite end portions 6a and 6a by the adhesive force) Elastic deformation until the gap is formed partially or entirely away from the state where the adsorbing layer opposite end portions 6a, 6a are adsorbed is limited.
　しかしながら、線状貫通部１０ａが粘着層５０を備えない領域に形成されることで、粘着層対峙端部５ａ，５ａが形成されないため、自己吸着層対峙端部６ａ，６ａの変位（具体的には、自己吸着層対峙端部６ａ，６ａ同士が吸着した状態から部分的又は全体的に離間して隙間が形成されるまでの弾性変形）が粘着層５０の粘着力によって阻害されるのを防止することができる。 However, since the linear penetrating portion 10a is formed in a region that does not include the adhesive layer 50, the adhesive layer opposite end portions 5a, 5a are not formed. Therefore, the displacement of the self adsorbing layer opposite end portions 6a, 6a (specifically, Prevents the self-adsorptive layer opposite end portions 6a and 6a from being adsorbed by the adhesive force of the adhesive layer 50 from elastic deformation until the gap is formed partially or entirely apart from each other. can do.
　換言すれば、線状貫通部１０ａでは、本体層対峙端部４ａ，４ａ同士が当接した状態になると共に、自己吸着層対峙端部６ａ，６ａ同士が当接した状態になる。一方、粘着層５０には、線状貫通部１０ａを構成するように対峙する端部が形成されない（つまり、通気ラベル１０では、第一実施形態のような粘着層対峙端部５ａ，５ａが形成されない）。このため、線状貫通部１０ａは、自己吸着層対峙端部６ａ，６ａ同士が吸着する力によってのみ密閉された状態となる。これにより、第一実施形態のように、粘着層対峙端部５ａ，５ａ同士の粘着力によって、線状貫通部１ａの開閉が制御される場合よりも、容易に（具体的には、内圧と外圧との差が低い状態であっても）線状貫通部１０ａを開くことができる。 In other words, in the linear penetration portion 10a, the main body layer opposite end portions 4a, 4a are in contact with each other, and the self-adsorbing layer opposite end portions 6a, 6a are in contact with each other. On the other hand, the adhesive layer 50 is not formed with end portions that confront each other so as to constitute the linear through portion 10a (that is, the air-permeable label 10 is formed with the adhesive layer opposite end portions 5a and 5a as in the first embodiment. Not) For this reason, the linear penetration part 10a will be in the state sealed only by the force which the self-adsorption layer opposing edge part 6a, 6a adsorb | sucks. Thus, as in the first embodiment, it is easier (specifically, the internal pressure and the internal pressure) than when the opening and closing of the linear penetration portion 1a is controlled by the adhesive force between the adhesive layer opposite end portions 5a and 5a. The linear through-hole 10a can be opened (even if the difference from the external pressure is low).
＜第三実施形態＞
　次に、本発明の第三実施形態について、図４（ｂ）を用いて説明する。第三実施形態に係る通気ラベル１１は、第一実施形態に係る通気ラベル１と比較すると、主に、線状貫通部１１ａの構成が異なるものである。これに伴い、粘着層５１，自己吸着層６の構成も一部異なる。従って、以下では、第一実施形態と異なる点を中心に説明し、同一の構成に対しては同一の符号を付すこととして説明を省略する。 <Third embodiment>
Next, a third embodiment of the present invention will be described with reference to FIG. The ventilation label 11 according to the third embodiment is mainly different from the ventilation label 1 according to the first embodiment in the configuration of the linear through-hole 11a. Accordingly, the structures of the adhesive layer 51 and the self-adsorption layer 6 are also partially different. Therefore, below, it demonstrates centering on a different point from 1st embodiment, and abbreviate | omits description by attaching | subjecting the same code | symbol to the same structure.
　通気ラベル１１は、本体層４の外周に沿って環状に形成された粘着層５１が本体層４の外周部に積層される。一方、自己吸着層６は、本体層４における粘着層５１が積層されていない領域（具体的には、環状の粘着層５０の内側の領域）に積層される。つまり、粘着層５０は、自己吸着層６の周囲を囲むように形成される。 In the ventilation label 11, an adhesive layer 51 formed in an annular shape along the outer periphery of the main body layer 4 is laminated on the outer peripheral portion of the main body layer 4. On the other hand, the self-adsorbing layer 6 is laminated in a region of the main body layer 4 where the adhesive layer 51 is not laminated (specifically, a region inside the annular adhesive layer 50). That is, the adhesive layer 50 is formed so as to surround the self-adsorption layer 6.
　また、通気ラベル１１は、被着体Ａに対して貼り付かない非貼付層７を備え、該非貼付層７と本体層４との間に自己吸着層６が形成される。本実施形態では、非貼付層７は、自己吸着層６を覆うように自己吸着層６に積層される。また、非貼付層７は、通気ラベル１１が被着体Ａに貼り付けられた際に、被着体Ａと当接するように構成される。そして、通気ラベル１１では、粘着層５１が積層されていない領域（具体的には、本体層４、自己吸着層６、および、非貼付層７が積層された領域）に線状貫通部１１ａを備える。なお、非貼付層７は、粘着性および吸着性を有さないシート材が積層されて構成されてもよく、粘着性および吸着性を有さない樹脂が印刷されて構成されてもよい。 The air-permeable label 11 includes a non-adhesion layer 7 that does not adhere to the adherend A, and a self-adsorption layer 6 is formed between the non-adhesion layer 7 and the main body layer 4. In this embodiment, the non-sticking layer 7 is laminated | stacked on the self-adsorption layer 6 so that the self-adsorption layer 6 may be covered. Further, the non-sticking layer 7 is configured to come into contact with the adherend A when the ventilation label 11 is attached to the adherend A. And in the ventilation label 11, the linear penetration part 11a is provided in the area | region where the adhesion layer 51 is not laminated | stacked (specifically area | region where the main body layer 4, the self-adsorption layer 6, and the non-sticking layer 7 were laminated | stacked). Prepare. The non-sticking layer 7 may be configured by laminating sheet materials that do not have adhesiveness and adsorptivity, or may be configured by printing a resin that does not have adhesiveness and adsorptivity.
　斯かる線状貫通部１１ａでは、線状貫通部１１ａを構成する非貼付層７の対峙する端部７ａ，７ａ同士、本体層対峙端部４ａ，４ａ同士、自己吸着層対峙端部６ａ，６ａ同士がそれぞれ当接した状態になる。一方、粘着層５１には、線状貫通部１１ａを構成するように対峙する端部が形成されない（つまり、通気ラベル１１では、第一実施形態のような粘着層対峙端部５ａ，５ａが形成されない）。このため、線状貫通部１１ａは、自己吸着層対峙端部６ａ，６ａ同士の吸着力によってのみ密閉された状態となる。これにより、第一実施形態のように、粘着層対峙端部５ａ，５ａ同士の粘着力によって、線状貫通部１ａの開閉が制御される場合より、容易に（具体的には、内圧と外圧との差が低い状態であっても）線状貫通部１１ａを開くことができる。 In such a linear penetrating portion 11a, the opposing end portions 7a, 7a of the non-sticking layer 7 constituting the linear penetrating portion 11a, the main body layer opposite end portions 4a, 4a, and the self-adsorbing layer opposite end portions 6a, 6a. They are in contact with each other. On the other hand, the adhesive layer 51 is not formed with end portions that confront each other so as to constitute the linear penetration portion 11a (that is, the air-permeable label 11 is formed with the adhesive layer opposite end portions 5a and 5a as in the first embodiment. Not) For this reason, the linear penetration part 11a will be in the state sealed only by the adsorption | suction force of self-adsorption layer opposing edge part 6a, 6a. This makes it easier (specifically, the internal pressure and the external pressure) than the case where the opening and closing of the linear penetration portion 1a is controlled by the adhesive force between the adhesive layer opposite end portions 5a and 5a as in the first embodiment. The linear through-hole 11a can be opened (even if the difference between the linear penetration portion 11a is low).
　また、通気ラベル１１は、被着体Ａに貼り付かない非貼付領域８を環状の貼付領域２の内側に備える。具体的には、通気ラベル１１は、自己吸着層６および非貼付層７と粘着層５１との間に空間（以下、ラベル内空間とも記す）１１Ｒを備え、該該ラベル内空間１１Ｒを備える領域と、非貼付層７を備える領域とによって非貼付領域８が構成される。 Further, the ventilation label 11 includes a non-sticking area 8 that does not stick to the adherend A inside the annular sticking area 2. Specifically, the ventilation label 11 includes a space (hereinafter also referred to as a label internal space) 11R between the self-adsorption layer 6 and the non-adhesive layer 7 and the adhesive layer 51, and the region including the label internal space 11R. And the non-sticking area | region 8 is comprised by the area | region provided with the non-sticking layer 7. FIG.
　斯かる通気ラベル１１は、ラベル内空間１１Ｒを備える領域が被着体Ａの貫通孔Ａ１と重なるように（即ち、ラベル内空間１１Ｒが貫通孔Ａ１と連通するように）被着体Ａに貼り付けられる。この際、非貼付層７は、被着体Ａにおける貫通孔Ａ１から離間した位置に当接した状態となり、線状貫通部１１ａは、被着体Ａにおける貫通孔Ａ１から離間した位置に配置される。斯かる状態において、内部空間Ｒ１の気体が貫通孔Ａ１から排出されることで、ラベル内空間１１Ｒ内に気体が流入し、ラベル内空間１１Ｒの気圧が上昇する。そして、ラベル内空間１１Ｒの気圧の上昇によって、通気ラベル１１及び／又は被着体Ａが変形することで、非貼付層７が被着体Ａから離間して、非貼付層７と被着体Ａとの間に隙間が形成される。これにより、斯かる隙間に流入した気体が線状貫通部１１ａを通じて外部空間Ｒ２へ排出される。つまり、通気ラベル１１における線状貫通部１１ａが形成された領域が被着体Ａに当接するように、通気ラベル１１が被着体Ａに貼り付けられた状態であっても、線状貫通部１１ａを通じて容易に気体の排出を行うことができる。 Such a ventilation label 11 is attached to the adherend A so that the region including the label inner space 11R overlaps the through hole A1 of the adherend A (that is, the label inner space 11R communicates with the through hole A1). Attached. At this time, the non-sticking layer 7 is in contact with a position separated from the through hole A1 in the adherend A, and the linear through portion 11a is disposed at a position separated from the through hole A1 in the adherend A. The In such a state, the gas in the internal space R1 is discharged from the through-hole A1, so that the gas flows into the label inner space 11R and the pressure in the label inner space 11R increases. Then, the air-permeable label 11 and / or the adherend A are deformed by the increase in the atmospheric pressure in the label internal space 11R, so that the non-adhesive layer 7 is separated from the adherend A, and the non-adhesive layer 7 and the adherend are separated. A gap is formed with A. Thereby, the gas which flowed into such a clearance is discharged to the external space R2 through the linear penetration part 11a. That is, even if the ventilation label 11 is attached to the adherend A so that the region where the linear penetration portion 11a of the ventilation label 11 is formed contacts the adherend A, the linear penetration portion Gas can be easily discharged through 11a.
