Description

本発明は、密閉ラベル、より詳しくは、包装容器の表面に繰り返し剥離可能に接合され、当該包装容器を密閉する密閉ラベル、および当該密閉ラベルを備える包装容器に関する。   The present invention relates to a hermetic label, and more particularly to a hermetic label that is releasably bonded to the surface of a packaging container and seals the packaging container, and a packaging container that includes the hermetic label.

従来、不織布やティッシュペーパーなどに薬液等を含浸させたウェットティッシュが広く知られている。このようなウェットティッシュは、携帯用の場合、軟質フィルム等で形成されて取出し口となる開口を有する包装袋に収納されて、流通および使用されるのが一般的である。   Conventionally, a wet tissue in which a non-woven fabric or tissue paper is impregnated with a chemical or the like is widely known. In the case of carrying, such a wet tissue is generally distributed and used by being housed in a packaging bag formed of a soft film or the like and having an opening serving as a take-out port.

このようなウェットティッシュにおいては、使用時まで包装袋内に収容されたウェットティッシュの湿潤性を保持し、かつ包装袋内への異物の混入等を防ぐため、開口には繰り返し剥離可能な密閉ラベルが取り付けられることが多い。この場合は、ウェットティッシュを取り出すときに密閉ラベルを剥離して開口を露出させ、取出し後に再度密閉ラベルを粘着して開口を密閉する。   In such a wet tissue, in order to maintain the wettability of the wet tissue contained in the packaging bag until use and to prevent foreign matter from entering the packaging bag, the opening label can be repeatedly peeled off. Is often attached. In this case, when the wet tissue is taken out, the sealing label is peeled to expose the opening, and after taking out, the sealing label is adhered again to seal the opening.

密閉ラベルはある程度剛性を有するフィルムで形成されることが多いため、開口が現れる状態まで開閉蓋を剥がしたときに、開閉蓋から手を離すと、自らの剛性および弾性により倒れ、意図せず開口が塞がれてしまうことがある。
このため、例えばウェットティッシュで幼児のおしりを拭いているとき等に、開口が塞がれているために２枚目のウェットティッシュが取り出せない等の事態が生じるため、不便となるという問題があった。 Since the sealing label is often formed of a film with some rigidity, when the lid is peeled off until the opening appears, if you release your hand from the lid, it will fall down due to its own rigidity and elasticity, and it will open unintentionally. May be blocked.
For this reason, for example, when the infant's butt is wiped with a wet tissue, there is a problem that the second wet tissue cannot be taken out because the opening is blocked, which is inconvenient. It was.

この問題を解決する技術として、特許文献１には、包装袋の開口を密閉する密閉部と、密閉部の少なくとも一部と接続され、包装袋に接合される支持部とを備えた密閉ラベルにおいて、密閉部と支持部との境界部に、密閉部を剥離する剥離方向と交差する方向に延びて密閉ラベルの基材の一部を剥離方向近位側領域と剥離方向遠位側領域とに離断するカット線を設けることが開示されている。   As a technique for solving this problem, Patent Document 1 discloses a sealing label including a sealing portion that seals an opening of a packaging bag and a support portion that is connected to at least a part of the sealing portion and joined to the packaging bag. The base part of the sealing label extends to the boundary part between the sealing part and the support part in a direction intersecting with the peeling direction for peeling the sealing part into the peeling direction proximal region and the peeling direction distal region. It is disclosed to provide a cut line that separates.

特許文献１に記載の技術によれば、カット線に達するまで密閉部を剥離すると、その後手を離しても密閉部は開口側に戻らず、ウェットティッシュ等の内容物を取り出し可能な状態が好適に保持される。   According to the technique described in Patent Document 1, when the sealing part is peeled off until reaching the cut line, the sealing part does not return to the opening side even if the hand is released thereafter, and a state in which contents such as a wet tissue can be taken out is suitable. Retained.

特開２０１２−２１８７６７号公報JP 2012-218767 A

特許文献１に記載の技術は、開口の露出状態を保持する上で優れた技術であるが、以下の点で改善の余地がある。すなわち、使用者によっては、開口が見えて内容物を取り出し可能な状態になった時点で密閉部の剥離を止めてしまうため、密閉部の剥離がカット線に達しない結果、剥離した密閉部が開口側に戻ってしまう可能性がある。   The technique described in Patent Document 1 is an excellent technique for maintaining the exposed state of the opening, but there is room for improvement in the following points. In other words, depending on the user, when the opening is visible and the contents can be taken out, peeling of the sealed portion is stopped, and as a result, the peeling of the sealed portion does not reach the cut line. There is a possibility of returning to the opening side.

密閉ラベル１が取り付けられる包装袋（包装容器）５０は、所定の形状に形成されて内容物を収容するものであり、例えば、表面（外側）からポリエチレンテレフタレート（ＰＥＴ）フィルム、アルミニウム箔、いわゆるシーラントと呼ばれるヒートシール性フィルムなどが順に積層されて接合された公知の積層フィルムから形成されている。積層フィルムは、例えばＰＥＴフィルムにアルミニウムまたはシリカまたはアルミナが蒸着されたもので、内面にヒートシール性フィルムが重ねられているようなものでもよい。 A first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view showing a packaging bag 50 to which the sealing label 1 of the present embodiment is attached. FIG. 2 is a left side view of the packaging bag 50, and FIG. 3 is a rear view of the packaging bag 50.
A packaging bag (packaging container) 50 to which the hermetic label 1 is attached is formed in a predetermined shape and accommodates the contents. For example, a polyethylene terephthalate (PET) film, an aluminum foil, so-called sealant from the surface (outside) It is formed from the well-known laminated | multilayer film in which the heat-sealable film etc. which are called were laminated | stacked in order, and were joined. The laminated film may be, for example, a film obtained by depositing aluminum, silica, or alumina on a PET film, and having a heat-sealable film laminated on the inner surface.

包装袋５０は、ヒートシール性フィルムを内側にして、内部に内容物１００を収容している（図８参照。）。本実施形態では、内容物１００として、不織布やティッシュペーパーなどに薬液等を含浸させたウェットティッシュ６０が収納されている。
包装袋５０を形成する積層フィルムは、水や酸素を透過せず、気密性に優れているため、ウェットティッシュ６０の乾燥を防ぎ、使用時まで湿潤状態を保持して収納することができる。包装袋５０の具体的形状および包装袋５０を構成する積層フィルムの層構成等は、内容物１００の特性等に応じて適宜変更されてよい。
包装袋５０の面の一つには、使用時にウェットティッシュ６０が取り出される取出し口（開口）５１が形成されている。取出し口５１の形状は適宜設定することができるが、本実施形態では平面視円形とされている。 The packaging bag 50 contains the contents 100 inside with the heat-sealable film inside (see FIG. 8). In the present embodiment, a wet tissue 60 in which a non-woven fabric or tissue paper is impregnated with a chemical solution or the like is stored as the content 100.
The laminated film forming the packaging bag 50 does not permeate water and oxygen and is excellent in airtightness. Therefore, the wet tissue 60 can be prevented from being dried and stored in a wet state until use. The specific shape of the packaging bag 50 and the layer configuration of the laminated film constituting the packaging bag 50 may be changed as appropriate according to the characteristics of the contents 100 and the like.
One of the surfaces of the packaging bag 50 is formed with an outlet (opening) 51 from which the wet tissue 60 is taken out during use. The shape of the take-out port 51 can be set as appropriate, but in the present embodiment, it is circular in plan view.

図４は、図１のI−I線における断面図である。密閉ラベル１は、図４に示すように、一方の面に粘着剤層２Ａが形成されたシート状またはフィルム状の第一基材２と、一方の面に粘着剤層３Ａが形成されたシート状またはフィルム状の第二基材３とが積層されて構成されている。第一基材２は、粘着剤層２Ａが第二基材３の粘着剤層３Ａと反対側の面に形成されることにより積層されている。第一基材２において、粘着剤層２Ａが設けられていない上面には、所望のデザインを実現するための印刷層２Ｂが形成され、さらに印刷層２Ｂを覆う保護層２Ｃが形成されている。保護層２Ｃは、ニス等の印刷により好適に形成することができるが、印刷層２Ｂおよび保護層２Ｃは本発明には必須でなく、設けられなくてもよい。   4 is a cross-sectional view taken along the line II of FIG. As shown in FIG. 4, the hermetic label 1 includes a sheet-like or film-like first base material 2 in which an adhesive layer 2 </ b> A is formed on one surface, and a sheet in which an adhesive layer 3 </ b> A is formed on one surface. The film-like or film-like second base material 3 is laminated. The first base material 2 is laminated by forming the pressure-sensitive adhesive layer 2 </ b> A on the surface of the second base material 3 opposite to the pressure-sensitive adhesive layer 3 </ b> A. In the first substrate 2, a printing layer 2 </ b> B for realizing a desired design is formed on the upper surface where the pressure-sensitive adhesive layer 2 </ b> A is not provided, and a protective layer 2 </ b> C that covers the printing layer 2 </ b> B is formed. The protective layer 2C can be suitably formed by printing such as varnish, but the printing layer 2B and the protective layer 2C are not essential to the present invention and may not be provided.

第二基材３の粘着剤層３Ａは、公知の再剥離可能な粘着剤層であり、粘着剤層３Ａが包装袋５０に接合されることにより、密閉ラベル１が取出し口５１を覆うように接合されている。粘着剤層２Ａの粘着強度は、粘着剤層３Ａの粘着強度よりも大きく設定されている。
第一基材２および第二基材３の材料としては、ＰＥＴや二軸延伸ポリプロピレン（ＯＰＰ）、あるいはこれらをブレンドしたものや、合成紙等を好適に用いることができる。 The pressure-sensitive adhesive layer 3 </ b> A of the second base material 3 is a known detachable pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer 3 </ b> A is joined to the packaging bag 50 so that the hermetic label 1 covers the take-out port 51. It is joined. The adhesive strength of the adhesive layer 2A is set larger than the adhesive strength of the adhesive layer 3A.
As materials for the first base material 2 and the second base material 3, PET, biaxially stretched polypropylene (OPP), a blend of these, synthetic paper, or the like can be suitably used.

図１及び図４に示すように、密閉ラベル１は、取出し口５１を密閉する密閉部１０と、密閉部１０に接続された支持部２０とを備えている。
密閉部１０は、第一端部１０Ａが略半円弧状とされ、第一端部１０Ａとは反対側の第二端部１０Ｂに向かって略同一幅で延びた後、切り込み２１（後述）により幅が狭められて支持部２０に接続されている。密閉部１０は平面視において略Ｄ字状に形成されている。密閉部１０は、第一端部１０Ａまたはその付近を持って第一端部１０Ａから第二端部１０Ｂに向かう方向（剥離方向）に剥離させることにより、包装袋５０の取出し口５１を露出させることができる。
なお、密閉部１０の形状は、本実施形態のものに限られず、意匠性等を考慮して適宜変更することができる。 As shown in FIGS. 1 and 4, the sealing label 1 includes a sealing portion 10 that seals the take-out port 51 and a support portion 20 that is connected to the sealing portion 10.
The sealing portion 10 has a first end portion 10A having a substantially semicircular arc shape, and extends with substantially the same width toward the second end portion 10B opposite to the first end portion 10A. The width is narrowed and connected to the support portion 20. The sealing part 10 is formed in a substantially D shape in plan view. The sealing portion 10 has the first end portion 10A or the vicinity thereof and peels it in the direction (peeling direction) from the first end portion 10A toward the second end portion 10B, thereby exposing the take-out port 51 of the packaging bag 50. be able to.
In addition, the shape of the sealing part 10 is not restricted to the thing of this embodiment, It can change suitably in consideration of the designability etc.

支持部２０には、密閉部１０の第二端部１０Ｂが接続されている。また、密閉部１０と支持部２０とは、剥離方向に延びる一対の切り込み２１によって区分されている。切り込み２１は、密閉部１０が剥離された際に支持部２０に剥離する力を作用しにくくする機能も有している。一対の切り込み２１間の距離は、第一端部１０Ａに近づくにつれて長くなっている。また、一対の切り込み２１の支持部側の端部は、第一端部１０Ａ側（剥離方向近位側）に折り返されており、密閉部１０を剥離した際に、切り込み２１の延長線上に裂け目が生じることを防いでいる。   The support portion 20 is connected to the second end portion 10B of the sealing portion 10. Moreover, the sealing part 10 and the support part 20 are divided by a pair of cuts 21 extending in the peeling direction. The notch 21 also has a function of making it difficult to apply a peeling force to the support part 20 when the sealing part 10 is peeled off. The distance between the pair of cuts 21 becomes longer as approaching the first end portion 10A. Further, the ends of the pair of cuts 21 on the support part side are folded back to the first end part 10A side (proximal direction in the peeling direction), and when the sealing part 10 is peeled off, a tear is formed on the extension line of the cuts 21. Is prevented from occurring.

図５は、第二基材３の平面図であり、図６は、第二基材３の底面図である。また、図７は第一基材２の底面図である。
図４から図６に示すように、密閉部には、第二基材３のみを切断するカット線１１および第二カット線１２が形成されている。カット線１１は、取出し口５１よりも一回り大きい略円形であり、取出し口５１を囲むように形成されている。第二カット線１２は、カット線１１の周囲に形成されている。第二カット線１２は、剥離方向近位側が略半円弧状であり、両端部が剥離方向と略平行に延びてそれぞれ一対の切り込み２１に達している。カット線１１と第二カット線１２との間の領域にある第二基材は、密閉部１０を剥離した際に取出し口５１の周縁を補強する補強部材１４とされている。補強部材１４は、取出し口５１の周囲を囲んでおり、剥離方向遠位側において、支持部２０まで延びている。 FIG. 5 is a plan view of the second base material 3, and FIG. 6 is a bottom view of the second base material 3. FIG. 7 is a bottom view of the first substrate 2.
As shown in FIGS. 4 to 6, a cut line 11 and a second cut line 12 that cut only the second base material 3 are formed in the sealed portion. The cut line 11 has a substantially circular shape that is slightly larger than the extraction port 51 and is formed so as to surround the extraction port 51. The second cut line 12 is formed around the cut line 11. The second cut line 12 has a substantially semicircular arc shape on the proximal side in the peeling direction, and both end portions extend substantially parallel to the peeling direction and reach a pair of cuts 21 respectively. The second base material in the region between the cut line 11 and the second cut line 12 is a reinforcing member 14 that reinforces the periphery of the take-out port 51 when the sealing part 10 is peeled off. The reinforcing member 14 surrounds the periphery of the take-out port 51 and extends to the support portion 20 on the distal side in the peeling direction.

第二カット線１２の剥離方向近位側の端部は、鋸歯状に形成されており、複数の突出部１２Ａを有している。
第二基材３において、粘着剤層２Ａに対向する面には、補強部材１４となる領域を第一基材２から剥離しやすくするための剥離ニスが塗布されている。剥離ニスが塗布されて形成された剥離領域１５は、図５に示すように、概ね補強部材１４を覆うように、かつカット線１１の内側に達しないように設定されている。また、剥離領域１５は、後述する支持部カット線２４の直線部２４ａまで延びている。
なお、図５において、剥離領域１５の外縁は、カット線１１および第二カット線１２との混同を防ぐため、破線で示している。 The end of the second cut line 12 on the proximal side in the peeling direction is formed in a sawtooth shape and has a plurality of protrusions 12A.
In the second substrate 3, a peeling varnish is applied to the surface facing the pressure-sensitive adhesive layer 2 </ b> A so as to make it easier to peel the region that becomes the reinforcing member 14 from the first substrate 2. As shown in FIG. 5, the peeling region 15 formed by applying the peeling varnish is set so as to substantially cover the reinforcing member 14 and not reach the inside of the cut line 11. Moreover, the peeling area | region 15 is extended to the linear part 24a of the support part cut line 24 mentioned later.
In FIG. 5, the outer edge of the peeling region 15 is indicated by a broken line in order to prevent confusion with the cut line 11 and the second cut line 12.

支持部２０のうち、一対の切り込み２１間には、図１および図７に示すように、第一基材２を厚さ方向に貫通して、剥離方向と略直交するように延びる支持部カット線２４が設けられている。支持部カット線２４の両端部は、剥離方向遠位側に延びている。これにより、支持部カット線２４は、全体として剥離方向遠位側に開口する略Ｕ字状に形成されている。支持部カット線２４の両端は、略Ｕ字状の開口内側に折り返されて剥離方向近位側に向いており、切り込み２１同様、密閉部１０を剥離した際に、支持部カット線２４の延長線上に裂け目が生じることを防いでいる。   As shown in FIGS. 1 and 7, among the support portions 20, as shown in FIGS. 1 and 7, a support portion cut that extends through the first base material 2 in the thickness direction and substantially orthogonal to the peeling direction. A line 24 is provided. Both end portions of the support portion cut line 24 extend to the distal side in the peeling direction. Thereby, the support part cut line 24 is formed in the substantially U shape opened to the peeling direction distal side as a whole. Both ends of the support part cut line 24 are folded back to the inside of the substantially U-shaped opening and face the proximal side in the peeling direction, and when the sealing part 10 is peeled off, like the cut 21, the support part cut line 24 is extended. This prevents the formation of tears on the line.

図７に示すように、支持部カット線２４のうち、剥離方向と略直交するように延びる直線部２４ａと、切り込み２１のうちもっとも剥離方向遠位側に位置する折り返し位置２１ａと、支持部カット線２４のうちもっとも剥離方向遠位側に位置する折り返し位置２４ｂとは、剥離方向近位側からこの順で並ぶようにそれぞれの位置が設定されている。すなわち、直線部２４ａが最も剥離方向近位側に位置し、折り返し位置２４ｂが最も剥離方向遠位側に位置し、折り返し位置２１ａは、剥離方向において直線部２４ａと折り返し位置２４ｂとの間に位置している。
なお、カット線１１および第二カット線１２は第一基材２には達していないため、図７ではカット線１１および第二カット線１２の位置を二点鎖線で示している。 As shown in FIG. 7, among the support part cut lines 24, a straight part 24 a extending so as to be substantially orthogonal to the peeling direction, a folding position 21 a located most distally in the peeling direction among the cuts 21, and a support part cut The folding position 24b located closest to the distal side in the peeling direction among the lines 24 is set so that the respective positions are arranged in this order from the proximal side in the peeling direction. That is, the straight line portion 24a is located closest to the peeling direction, the folding position 24b is located most distal to the peeling direction, and the folding position 21a is located between the straight line portion 24a and the folding position 24b in the peeling direction. doing.
In addition, since the cut line 11 and the 2nd cut line 12 have not reached the 1st base material 2, in FIG. 7, the position of the cut line 11 and the 2nd cut line 12 is shown with the dashed-two dotted line.

支持部カット線２４は、第二基材３に達しないように形成されてもよいし、第二基材３に達していてもよい。本実施形態では支持部カット線２４は第二基材３に達していないため、図５および図６では、支持部カット線２４の位置を二点鎖線で示している。   The support part cut line 24 may be formed so as not to reach the second base material 3, or may reach the second base material 3. In this embodiment, since the support part cut line 24 does not reach the second base material 3, in FIG. 5 and FIG. 6, the position of the support part cut line 24 is indicated by a two-dot chain line.

図４および図６に示すように、包装袋５０に接合される粘着剤層３Ａの面上であってカット線１１に囲まれた領域の周縁部には、糊殺し剤の網状または点状印刷による図示しない糊殺し処理が施されており、剥離強度が低下された糊殺し領域３Ｂとされている。糊殺し領域３Ｂにおける網状または点状印刷の密度は、設定した剥離強度によって決定されるものであり、たとえば、３０〜５０％とされてもよい。糊殺し処理を施す領域は、例えば図４に示す線幅Ｄ１の円形の環状とすればよい。なお、線幅Ｄ１は、少なくとも包装袋５０の平面視においてカット線１１と取出し口５１を形成するためのカットＣ（図４参照）との間に位置する領域を含むように設定されればよい。   As shown in FIG. 4 and FIG. 6, a paste or paste-like print of paste-killing agent is provided on the peripheral portion of the area surrounded by the cut line 11 on the surface of the pressure-sensitive adhesive layer 3 </ b> A joined to the packaging bag 50. A paste killing process (not shown) is performed, and the paste killing area 3B has a reduced peel strength. The density of the net-like or dot-like printing in the paste killing area 3B is determined by the set peel strength, and may be, for example, 30 to 50%. The area to be subjected to the paste killing process may be, for example, a circular ring having a line width D1 shown in FIG. In addition, the line width D1 should just be set so that the area | region located between the cut line 11 and the cut C (refer FIG. 4) for forming the extraction port 51 in planar view of the packaging bag 50 may be included at least. .

また、粘着剤層３Ａの面上であって、カット線１１の剥離方向近位側端部と接する一部の領域は、糊殺し領域３Ｂよりも剥離強度が低い強糊殺し領域３Ｃとされている。強糊殺し領域３Ｃの形成方法には特に限定はなく、例えば糊殺し領域３Ｂと同一の糊殺し剤をベタ印刷して形成してもよいし、糊殺し領域３Ｂに用いたものよりも強い糊殺し剤を、所定の密度で網状または点状印刷して形成してもよい。強糊殺し領域３Ｃは、糊殺し領域３Ｂと連続して設けられてもよいし、糊殺し領域３Ｂと離間して設けられてもよい。   Further, a part of the area on the surface of the pressure-sensitive adhesive layer 3A that is in contact with the proximal end portion in the peeling direction of the cut line 11 is defined as a strong paste killing area 3C having a lower peel strength than the paste killing area 3B. Yes. There is no particular limitation on the method of forming the strong paste-killing area 3C. For example, the same paste-killing agent as the paste-killing area 3B may be formed by solid printing, or a paste stronger than that used for the paste-killing area 3B. The killing agent may be formed by reticulation or dot printing at a predetermined density. The strong paste killing area 3C may be provided continuously with the paste killing area 3B, or may be provided apart from the paste killing area 3B.

さらに、粘着剤層３Ａの面上であって密閉部１０の剥離方向近位側端部にも、密閉部１０を剥離する際のきっかけとなるように糊殺し領域３Ｄが形成されている。糊殺し領域３Ｄは、糊殺し処理がされていない粘着剤層３Ａよりも剥離強度が低下されていればよく、糊殺し領域３Ｂおよび強糊殺し領域３Ｃとの剥離強度の強弱関係には特に制限はない。
本実施形態においては、糊殺し領域３Ｄの剥離方向遠位側は、略円弧状に形成されており、密閉部１０を剥離する際に密閉部１０に作用する力を分散させて密閉部１０にしわ等が生じにくくしている。 Further, a paste-killing region 3D is formed on the surface of the pressure-sensitive adhesive layer 3A and also at the end portion on the proximal side in the peeling direction of the sealing portion 10 so as to trigger the peeling of the sealing portion 10. The paste killing area 3D only needs to have a lower peel strength than the adhesive layer 3A that has not been subjected to the paste killing process, and is particularly limited in the strength relationship between the paste killing area 3B and the strong paste killing area 3C. There is no.
In this embodiment, the peeling direction distal side of the paste-killing region 3D is formed in a substantially arc shape, and the force acting on the sealing portion 10 when the sealing portion 10 is peeled is dispersed to the sealing portion 10. Wrinkles are less likely to occur.

本実施形態の密閉ラベル１は、取出し口５１の少なくとも一部が剥離方向において一対の切り込み２１の範囲内に位置するように包装袋５０に貼り付けられている。このような貼り付けを可能とするために、カット線１１の剥離方向遠位側端部は、図５に示すように、一対の切り込み２１のうち、剥離方向遠位側に位置する平行部２１ｂの範囲内に位置している。すなわち、平行部２１ｂとカット線１１の剥離方向遠位側端部とは、剥離方向において重なっている。   The hermetic label 1 of this embodiment is affixed to the packaging bag 50 so that at least a part of the take-out port 51 is located within the range of the pair of cuts 21 in the peeling direction. In order to enable such affixing, the peeling direction distal end of the cut line 11 is, as shown in FIG. 5, a parallel portion 21 b located on the distal side in the peeling direction of the pair of cuts 21. It is located within the range. That is, the parallel part 21b and the end part in the peeling direction of the cut line 11 overlap each other in the peeling direction.

包装袋５０を製造する際は、予め包装袋５０の材料となる積層フィルムＦに密閉ラベル１を位置決めして貼り付け、図４に示すように、積層フィルムＦにおいてカット線１１内に位置する部位に密閉ラベル１が貼られていない下面側から取出し口５１の形状のカットＣを入れて取出し口５１を形成しておく。カットＣの深さは、積層フィルムＦを確実に切断し、第二基材３を切断しない程度とされるのが好ましい。
その後、積層フィルムＦと、密閉ラベル１を貼っていないもう１枚の積層フィルムとを接合し、内容物を収容して密封すると包装袋５０が完成する。積層フィルムを２枚用いるのに代えて１枚の積層フィルムの端部を接合して略筒状にすることにより包装袋を形成してもよい。 When the packaging bag 50 is manufactured, the sealing label 1 is positioned and pasted on the laminated film F that is the material of the packaging bag 50 in advance, and the portion located in the cut line 11 in the laminated film F as shown in FIG. A cut-out C having the shape of the take-out port 51 is put into the take-out port 51 from the lower surface side where the sealing label 1 is not attached. The depth of the cut C is preferably set such that the laminated film F is reliably cut and the second base material 3 is not cut.
Thereafter, the laminated film F and another laminated film not attached with the sealing label 1 are joined, and the contents are accommodated and sealed, whereby the packaging bag 50 is completed. Instead of using two laminated films, a packaging bag may be formed by joining the ends of one laminated film into a substantially cylindrical shape.

上記のように形成された包装袋５０の使用時の動作について説明する。
使用者が、密閉部１０の第一端部１０Ａを持って剥離方向に引くと、密閉部１０が剥離方向近位側から徐々に剥離して包装袋５０から引き剥がされていく。
密閉部１０の剥離が第二カット線１２の剥離方向近位側端部に達すると、補強部材１４は、剥離領域１５により第一基材２に対する粘着強度が低下されているため、密閉部１０の剥離動作に追従せず、第一基材２から剥離して包装袋５０の取出し口５１の周囲に残存する。 The operation | movement at the time of use of the packaging bag 50 formed as mentioned above is demonstrated.
When the user holds the first end portion 10 </ b> A of the sealing portion 10 and pulls it in the peeling direction, the sealing portion 10 is gradually peeled from the proximal side in the peeling direction and peeled off from the packaging bag 50.
When the peeling of the sealing portion 10 reaches the proximal end portion in the peeling direction of the second cut line 12, the reinforcing member 14 has a reduced adhesive strength with respect to the first substrate 2 due to the peeling region 15, and thus the sealing portion 10 The peeling operation does not follow the peeling operation, and peels off from the first base material 2 and remains around the take-out port 51 of the packaging bag 50.

密閉部１０の剥離がカット線１１の剥離方向近位側端部に達すると、第二基材３のうちカット線１１の内側の領域が包装袋５０から引き剥がされる。このとき、包装袋５０を形成する積層フィルムＦのうちカットＣで囲まれた領域（以下、「開口形成領域Ｆ１」と称する。）は、第二基材３の粘着剤層３Ａに強固に粘着されているため、図８および図９に示すように、第二基材３に粘着されたまま密閉部１０とともに移動し、密閉部１０とともに包装袋５０の他の領域から離間して取出し口５１が開口される。このとき、カット線１１の内側に位置して補強部材１４に囲まれた第二基材３の剥離方向近位側端部は、強糊殺し領域３Ｃにより、包装袋５０との粘着強度が最も低くなっているため、第一基材２に確実に追従して包装袋５０から好適に剥離される。
なお、図９では、断面を取った位置によって密閉部１０と支持部２０とが切り離されているように見えるが、異なる断面では両者が接続されており、図８に示すように切り離されてはいない。 When the peeling of the sealing portion 10 reaches the proximal end in the peeling direction of the cut line 11, the region inside the cut line 11 of the second base material 3 is peeled off from the packaging bag 50. At this time, a region surrounded by the cut C (hereinafter referred to as “opening formation region F1”) in the laminated film F forming the packaging bag 50 is firmly adhered to the pressure-sensitive adhesive layer 3A of the second base material 3. Therefore, as shown in FIGS. 8 and 9, it moves together with the sealing part 10 while being adhered to the second base material 3, and is separated from the other region of the packaging bag 50 together with the sealing part 10. Is opened. At this time, the proximal end in the peeling direction of the second base material 3 located inside the cut line 11 and surrounded by the reinforcing member 14 has the highest adhesive strength with the packaging bag 50 due to the strong paste-killing region 3C. Since it is low, it reliably follows the first substrate 2 and is suitably peeled off from the packaging bag 50.
In addition, in FIG. 9, although it seems that the sealing part 10 and the support part 20 are cut | disconnected by the position which took the cross section, both are connected in a different cross section, and as shown in FIG. Not in.

密閉部１０がさらに包装袋５０から剥離されても、第一基材２が第二基材３から剥離され続けるため、第二基材３のうち、カット線１１、第二カット線１２、および一対の切り込み２１に囲まれた領域は、包装袋５０に粘着されたままで密閉部１０に追随しない。
密閉部１０の剥離が密閉部１０と支持部２０との接続部位にある支持部カット線２４に達すると、剥離する力の一部は支持部カット線２４により第一基材２に伝わらないため、直線部２４ａの両側の領域のみにおいて第一基材２が第二基材３から剥離される。したがって、密閉部１０と支持部２０とを接続する部位の面積が小さくなり、接続部位の剛性（コシ）が低下する。
その結果、密閉部１０を支持部カット線２４まで剥がすと、使用者が密閉部１０から手を離しても剥離方向近位側に戻らず、取出し口５１の露出状態が保持される。 Even if the sealing part 10 is further peeled from the packaging bag 50, the first base material 2 continues to be peeled from the second base material 3. Therefore, among the second base materials 3, the cut line 11, the second cut line 12, and The region surrounded by the pair of cuts 21 remains adhered to the packaging bag 50 and does not follow the sealed portion 10.
When the peeling of the sealing part 10 reaches the support part cut line 24 at the connection part between the sealing part 10 and the support part 20, part of the peeling force is not transmitted to the first base material 2 by the support part cut line 24. The first base material 2 is peeled from the second base material 3 only in the regions on both sides of the linear portion 24a. Therefore, the area of the site | part which connects the sealing part 10 and the support part 20 becomes small, and the rigidity (koshi) of a connection site | part falls.
As a result, when the sealing part 10 is peeled to the support part cut line 24, even if the user removes his / her hand from the sealing part 10, it does not return to the proximal side in the peeling direction, and the exposed state of the take-out port 51 is maintained.

使用者は、包装袋５０を手元に置いたまま、取出し口５１からウェットティッシュ６０を取り出して所望の作業をすることができる。２枚目、３枚目のウェットティッシュを取り出す際も、取出し口５１の露出状態が保持されているため、再度密閉部を剥離する必要はなく、スムーズに作業を行うことができる。   The user can perform a desired operation by taking out the wet tissue 60 from the take-out port 51 while keeping the packaging bag 50 at hand. Even when the second and third wet tissues are taken out, the exposed state of the take-out port 51 is maintained, so that it is not necessary to peel off the sealed portion again, and the operation can be performed smoothly.

また、密閉部１０を包装袋５０から剥離した状態において、第二基材３の一部からなる補強部材１４が取出し口５１の周囲に残存する。これにより、取出し口５１周囲の破損やしわの発生等を防ぎ、包装袋５０の美観および再密閉時の密閉性が好適に保持される。   Further, in a state where the sealing part 10 is peeled from the packaging bag 50, the reinforcing member 14 made of a part of the second base material 3 remains around the take-out port 51. As a result, damage around the take-out port 51, generation of wrinkles, and the like are prevented, and the aesthetic appearance of the packaging bag 50 and the sealing performance at the time of resealing are suitably maintained.

ウェットティッシュ６０の使用後は、密閉部１０を再び包装袋５０に接合して取出し口５１を密閉すると、包装袋５０内のウェットティッシュ６０の乾燥が防止されるとともに、包装袋５０内への異物の進入も防止される。   After the use of the wet tissue 60, when the sealing portion 10 is joined again to the packaging bag 50 and the take-out port 51 is sealed, the wet tissue 60 in the packaging bag 50 is prevented from being dried and foreign matter in the packaging bag 50 is prevented. Intrusion is also prevented.

本実施形態の密閉ラベル１によれば、第二基材にカット線１１および第二カット線１２が設けられ、これらカット線により規定される補強部材１４上に剥離領域１５が形成されているため、密閉部１０を剥離した際に密閉部１０と支持部２０との接続部位が薄くなり、積層された密閉ラベル１自体よりも剛性が低くなる。   According to the sealed label 1 of the present embodiment, the cut line 11 and the second cut line 12 are provided on the second base material, and the peeling region 15 is formed on the reinforcing member 14 defined by these cut lines. When the sealing part 10 is peeled off, the connecting portion between the sealing part 10 and the support part 20 becomes thin, and the rigidity becomes lower than that of the laminated sealing label 1 itself.

したがって、使用者が密閉部の支持を解除しても、密閉部が剥離前の位置に戻ることがなく、取出し口５１が露出した状態が好適に保持される。その結果、包装袋５０の取出し口５１を開閉可能に密閉する目的で使用すると、取出し口５１の露出状態を好適に保持して、内容物を取り出しやすくすることができる。   Therefore, even if the user releases the support of the sealing portion, the sealing portion does not return to the position before peeling, and the state where the take-out port 51 is exposed is preferably maintained. As a result, when the take-out port 51 of the packaging bag 50 is used for the purpose of being able to be opened and closed, the exposed state of the take-out port 51 can be suitably maintained and the contents can be easily taken out.

上述した作用は、密閉部１０の剥離が支持部カット線２４まで達しないと充分に発現しない。本実施形態の包装袋５０においては、取出し口５１の少なくとも一部が剥離方向において一対の切り込み２１の範囲内に位置しており、取出し口５１の周囲に設けられたカット線１１の最も剥離方向遠位側は、切り込み２１の剥離方向遠位側領域である平行部２１ｂの範囲内に位置している。このため、取出し口５１を充分に露出させるためには、密閉部１０を切り込み２１よりも剥離方向遠位側まで剥離しなければならない。したがって、使用者が取出し口を充分露出させようとすると、密閉部１０の剥離が支持部カット線２４まで達しやすくなり、剥離が充分でないことにより密閉部が戻ってしまうことが好適に抑制される。その結果、取出し口５１が露出された状態をより確実に持続可能な包装袋とすることができる。   The above-described action is not fully manifested unless the peeling of the sealing part 10 reaches the support part cut line 24. In the packaging bag 50 of this embodiment, at least a part of the take-out port 51 is located within the range of the pair of cuts 21 in the peel direction, and the most peel direction of the cut line 11 provided around the take-out port 51. The distal side is located within the range of the parallel portion 21b which is the distal side region of the cut 21 in the peeling direction. For this reason, in order to fully expose the take-out port 51, the sealing portion 10 must be peeled to the distal side in the peeling direction from the notch 21. Therefore, when the user tries to expose the take-out port sufficiently, the peeling of the sealing portion 10 easily reaches the support portion cut line 24, and the sealing portion is preferably prevented from returning due to insufficient peeling. . As a result, the state in which the take-out port 51 is exposed can be more reliably made into a sustainable packaging bag.

また、密閉ラベル１では、支持部カット線２４に達するまで密閉部１０を剥離すると、それ以降密閉部１０を引く力は、もっぱら第一基材２と第二基材３とを粘着する粘着剤層２Ａに作用し、粘着剤層３Ａにはほとんど作用しない。
したがって、密閉部１０を引く力は支持部２０を包装袋５０から引き剥がすようには作用しない。加えて、粘着剤層２Ａの粘着強度は粘着剤層３Ａの粘着強度よりも大きいため、第一基材２が第二基材３から剥離される事態も発生しにくい。これにより、密閉部１０の剥離時に密閉ラベル１全体が包装袋５０から剥離されてしまう事態を好適に防止することができる。 In the sealed label 1, when the sealed portion 10 is peeled until the support portion cut line 24 is reached, the force that pulls the sealed portion 10 thereafter sticks the first substrate 2 and the second substrate 3 exclusively. It acts on the layer 2A and hardly acts on the pressure-sensitive adhesive layer 3A.
Therefore, the force pulling the sealing part 10 does not act so as to peel the support part 20 from the packaging bag 50. In addition, since the adhesive strength of the pressure-sensitive adhesive layer 2 </ b> A is larger than the pressure-sensitive adhesive strength of the pressure-sensitive adhesive layer 3 </ b> A, a situation where the first base material 2 is peeled off from the second base material 3 hardly occurs. Thereby, the situation where the sealing label 1 whole is peeled from the packaging bag 50 at the time of peeling of the sealing part 10 can be prevented suitably.

密閉部を剥離する力が強すぎると、密閉部と支持部との接続部位において、第二基材から剥離された第一基材が切り込み２１を超えて裂けたり、密閉部が支持部からちぎれてしまったりする可能性がある。本実施形態の密閉ラベル１においては、支持部カット線２４の直線部２４ａおよび折り返し位置２４ｂ、並びに切り込み２１の折り返し位置２１ａを、剥離方向における位置が非同一となるように剥離方向に並べて配置することでこのような過剰な剥離力量の吸収あるいは分散を図っている。
すなわち、剥離される第一基材に作用する力は、まず最も剥離方向近位側にある直線部２４ａで吸収され、その後、折り返し位置２１ａで吸収され、さらに、折り返し位置２４ｂで吸収される。これにより、剥離操作に伴って密閉部の第一基材に作用する過剰な力量が吸収または分散され、密閉部の裂けやちぎれ等が好適に防止される。
本発明においては、上述した３つの吸収部位の剥離方向における並び順に特に制限はないが、支持部カット線２４の２つの吸収部位が剥離方向において連続する並び順であると、力量の吸収が３段階にならない可能性がある。したがって、直線部２４ａと折り返し位置２４ｂとの間に、支持部カット線の一部でない折り返し位置２１ａが位置する本実施形態の並び順が、３段階吸収を確実にする上で優れていると言える。 If the force to peel off the sealed portion is too strong, the first base material peeled off from the second base material will tear beyond the notch 21 at the connection site between the sealed portion and the support portion, or the sealed portion will tear off from the support portion. There is a possibility that it will be. In the sealed label 1 of the present embodiment, the linear portion 24a and the folding position 24b of the support portion cut line 24 and the folding position 21a of the cut 21 are arranged side by side in the peeling direction so that the positions in the peeling direction are not the same. In this way, absorption or dispersion of such an excessive peeling force amount is achieved.
That is, the force acting on the first base material to be peeled is first absorbed by the linear portion 24a closest to the peeling direction, then absorbed at the folding position 21a, and further absorbed at the folding position 24b. Thereby, the excessive force which acts on the 1st base material of a sealing part with peeling operation | movement is absorbed or disperse | distributed, and the tear of a sealing part, a tear, etc. are prevented suitably.
In the present invention, there is no particular limitation on the order in which the three absorption sites described above are arranged in the peeling direction. However, if the two absorption sites of the support portion cut line 24 are arranged in the order in which the two absorption sites are continuous, the absorption of power is 3. There is a possibility that it is not in a stage. Therefore, it can be said that the arrangement order of the present embodiment in which the folding position 21a that is not a part of the support section cut line is located between the straight line portion 24a and the folding position 24b is excellent in ensuring three-stage absorption. .

さらに、補強部材１４の剥離方向近位側端部は、第三カット線１２に設けられた突出部１２Ａにより、複数の突出部１４Ａを有するように形成されているため、密閉部１０の剥離が第三カット線１２の剥離方向近位側端部に達したときに、補強部材１４を包装袋５０から引きはがすように作用する力が一点に集中せず、突出部１４Ａの各々に分散して作用する。したがって、当該力の最大値が低下して補強部材１４が包装袋５０から剥離されにくくなり、より確実に補強部材１４を包装袋５０上に残存させることができる。   Further, the proximal end portion in the peeling direction of the reinforcing member 14 is formed so as to have a plurality of protruding portions 14A by the protruding portions 12A provided on the third cut line 12, so that the sealing portion 10 is peeled off. When the proximal end in the peeling direction of the third cut line 12 is reached, the force acting so as to peel the reinforcing member 14 from the packaging bag 50 is not concentrated on one point, but distributed to each of the protruding portions 14A. Works. Therefore, the maximum value of the force is reduced and the reinforcing member 14 is hardly peeled off from the packaging bag 50, and the reinforcing member 14 can remain on the packaging bag 50 more reliably.

また、粘着剤層３Ａの所定の領域に網状または点状の糊殺し領域３Ｂが形成されているため、当該領域には、粘着強度の相対的に高い部位と低い部位とが網状または点状に分布している。このため、当該領域全面に対して糊殺し処理を行う場合に比べて、ウェットティッシュ６０に含浸されていた薬液等が当該領域に広がりにくい。その結果、開口形成領域Ｆ１が第二基材３から剥離されたり、補強部材１４が包装袋５０から剥離されたりする等の不具合を好適に防止することができる。加えて、取出し口５１を再度密閉する際に、密閉部の粘着位置がずれても、糊殺し領域３Ｂにおいて剥離強度が適度に低下されているため、比較的容易に位置の修正を行うことができる。   In addition, since a net-like or dot-like paste-killing region 3B is formed in a predetermined region of the pressure-sensitive adhesive layer 3A, the region having relatively high and low adhesive strength in the region is in a net-like or dot-like shape. Distributed. For this reason, the chemical | medical solution etc. which were impregnated in the wet tissue 60 are hard to spread to the said area | region compared with the case where the paste-killing process is performed with respect to the whole area | region. As a result, problems such as the opening forming region F1 being peeled off from the second base material 3 and the reinforcing member 14 being peeled off from the packaging bag 50 can be suitably prevented. In addition, when the take-out port 51 is sealed again, even if the sticking position of the sealed portion is shifted, the peel strength is moderately reduced in the paste-killing region 3B, so that the position can be corrected relatively easily. it can.

本実施形態では、包装袋５０の一部である開口形成領域Ｆ１が密閉部１０に粘着されて取出し口５１が露出される例を説明したが、これに代えて、予め開口形成領域Ｆ１を除去して包装袋を形成しておき、密閉部において取出し口を覆う領域の粘着剤層３Ａに公知の糊殺し処理を施しておいてもよい。   In the present embodiment, the example in which the opening forming area F1 which is a part of the packaging bag 50 is adhered to the sealing portion 10 and the takeout port 51 is exposed has been described, but instead, the opening forming area F1 is removed in advance. Then, a packaging bag may be formed, and the adhesive layer 3A in the region covering the take-out port in the sealed portion may be subjected to a known paste killing process.

以上、本発明の一実施形態について説明したが、本発明の技術範囲は上記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において各構成要素に種々の変更を加えたり、削除したり、あるいは各実施形態における構成要素を適宜組み合わせたりすることが可能である。   Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, and various modifications may be made to each component without departing from the spirit of the present invention. It is possible to delete, or to appropriately combine the components in each embodiment.

例えば、本発明の密閉ラベルおよび包装容器において、補強部材に設けられる突出部や第二基材における強糊殺し領域は必須ではない。実際の包装容器においては、粘着剤層の構成や包装袋の材質等により粘着強度や剥離強度の好適な値が異なるため、必要に応じて上記構成を組み合わせ、密閉部の剥離時における補強部材の包装袋への残存や開口形成領域が粘着した第二基材の包装袋からの剥離等を確実に実現できるようにすればよい。   For example, in the sealed label and the packaging container of the present invention, the protruding portion provided in the reinforcing member and the strong paste-killing region in the second base material are not essential. In actual packaging containers, suitable values for adhesive strength and peel strength differ depending on the composition of the pressure-sensitive adhesive layer and the material of the packaging bag, etc. What is necessary is just to be able to implement | achieve peeling from the packaging bag of the 2nd base material which the remaining to the packaging bag, the opening formation area | region adhered, etc. reliably.

さらに、補強部材に形成される突出部についても、上述のような先端が鋭い形状には限られず、例えば先端が丸められた形状としてもよい。また、突出部を設ける個数も適宜決定することができ、より広範囲に多数設けても構わない。
