The present invention relates to a package in which a lid label that can be held in a sealed state by closing the lid label after removal is configured to be openable and closable.

従来、例えばウェットティッシュ等を収容するための包装体として、被包装物を、非通気性のシート状包装材をもって密封包装するとともに、該包装材の上片に、ほぼＵ字状の切込み線を付設し、かつその上方に、前記包装材より硬質のシート材料よりなり、かつ中央部に前記Ｕ字状の切込み線の端末部を除く部分より大寸の開口が形成された硬質シートを固着し、さらにその上方より、前記開口を覆う寸法のシート状外蓋を、接着剤をもって、前記硬質シートの上面及び硬質シートの開口より上方に臨む包装材の上面に、剥離可能でかつ再接着可能な程度に接着することにより、前記外蓋の剥離時に、前記切込み線の内部領域たる内蓋が、包装材との連設部分を残して、外蓋とともに包装材から引き剥がされ、その後に被包装物取り出し用の開口が形成されるようにした密封包装体が、知られている（例えば、特許文献１参照）。 Conventionally, for example, as a package for containing a wet tissue or the like, an article to be packaged is hermetically sealed with a non-breathable sheet-like packaging material, and a substantially U-shaped cut line is formed on the upper piece of the packaging material. A hard sheet made of a sheet material harder than the packaging material and having a larger opening than the portion of the U-shaped cut line at the center is attached to the upper part. Further, from above, a sheet-like outer lid having a size covering the opening can be peeled and reattached to the upper surface of the hard sheet and the upper surface of the packaging material facing the opening of the hard sheet with an adhesive. When the outer lid is peeled off, the inner lid, which is the inner region of the score line, is peeled off from the packaging material together with the outer lid, leaving a continuous connection portion with the packaging material, and then packaged For picking up objects Sealed package which is adapted opening is formed are known (e.g., see Patent Document 1).

このような密封包装体は、プラスチック容器に収納されたものに比べ、嵩張ることもなく携帯用に適した便利な形態である。しかしながら、近年、商品の多様化に伴い、含浸させるアルコール等の薬液量を多くしたウェットティッシュ等も商品化され、これらの商品の場合には特許文献１に開示された技術では、包装材の上片に付設された切込み線は完全に切断された切断線、又は易断性の線とされているために該切込み線からアルコール成分が浸透し、製品保管中に蓋ラベルが自然に剥れることが稀にあるという問題がある。
特開平６−４８４７５号公報 Such a sealed package is a convenient form suitable for portability without being bulky as compared with the one housed in a plastic container. However, in recent years, with the diversification of products, wet tissues and the like with a large amount of chemicals such as alcohol to be impregnated have been commercialized. In the case of these products, the technology disclosed in Patent Document 1 Since the cut line attached to the piece is a cut line that is completely cut or easily cut, the alcohol component penetrates from the cut line, and the lid label naturally peels off during product storage. There is a problem that there are rarely.

本発明の包装体は、内容物を密封包装する合成樹脂を主体とする軟質の積層シートから形成された包装袋と、保型性基材層の一方の面に感圧接着剤層が設けられ、積層シートより硬質の保型性シートと、蓋基材層の一方の面に再剥離再接着可能な粘着剤層が設けられた蓋ラベルを備え、包装袋の外面に保型性シートの感圧接着剤層面を当接させて保型性シートを固着させ、保型性シートに蓋ラベルの粘着剤層面を当接させて蓋ラベルを貼設させた包装体であって、保型性シートには、蓋ラベルが接着された領域内に開口部を形成するための保型性シートを貫通する切目線が閉じた形状で形成されると共に当該領域内の一部に感圧接着剤層面に遮蔽層が形成され、積層シートには、保型性シートの切目線で囲まれた領域と対向する領域内に積層シート側から保型性シート側に向って積層シートを半抜きするハーフカットからなる分断線が閉じた形状で形成され、当該分断線で囲まれた部分が取出し口部とされると共に保型性シートの切目線で囲まれた領域と積層シートの分断線で囲まれた部分が蓋ラベルと一体化されている構成とすることにより、蓋ラベルの一端部側より保型性シートとの間で剥離でき、保型性シートの切目線で囲まれた領域と積層シートの分断線で囲まれた部分が蓋ラベルと一体化されているために切目線に囲まれた領域の保型性シートは切目線に沿って切取られ、分断線に囲まれた部分の積層シートは分断線に沿って切取られて蓋ラベルに接着したままとなって、保型性シートには開口部が形成され積層シートには取出し口が形成され、保型性シートの開口部を介して積層シートの取出し口より内容物を容易に取り出せるという効果を奏するものである。また、積層シートに形成された分断線がハーフカットであること、さらには分断線の上には保型性シートが固着されており、内容物に含有される例えばアルコール成分が分断線から浸透することを防止でき、例え、浸透したとしても保型性シートで遮断されるために蓋ラベルの粘着剤層の接着力低下がなく、製品保管中に蓋ラベルの自然剥離を防止することができるものである。また、蓋ラベルは再剥離再接着可能な粘着剤層が設けられており、蓋ラベルは保型性シートの開口部を除く部分で蓋ラベルが保型性シートと剥離可能で且つ、剥離した部分が再接着可能な開閉自在な構成となり、内容物の乾燥、吸湿あるいは外部からの異物混入を防ぐことができる。 The package of the present invention has a packaging bag formed of a soft laminated sheet mainly composed of a synthetic resin for hermetically sealing the contents, and a pressure-sensitive adhesive layer on one surface of the shape-retaining substrate layer. The cover sheet is provided with a mold-holding sheet that is harder than the laminated sheet, and a lid label provided with an adhesive layer that can be re-removed and re-adhered on one surface of the lid base material layer. A packaging body in which a pressure-sensitive adhesive layer surface is brought into contact to fix a shape-retaining sheet, and a pressure-sensitive adhesive layer surface of the lid label is brought into contact with the shape-retaining sheet, and the lid label is affixed. In the region where the lid label is adhered, the cut line passing through the shape-retaining sheet for forming the opening is formed in a closed shape, and the pressure sensitive adhesive layer surface is partially formed in the region. A shielding layer is formed, and the laminated sheet is laminated in a region facing the region surrounded by the score line of the shape-retaining sheet. The parting line consisting of a half cut that half-pulls the laminated sheet from the sheet side toward the mold-holding sheet side is formed in a closed shape, and the part surrounded by the parting line is used as the take-out port and the shape is maintained. The region surrounded by the cut line of the adhesive sheet and the portion surrounded by the dividing line of the laminated sheet are integrated with the lid label, so that the space between the end of the lid label and the shape-retaining sheet is integrated. Since the area surrounded by the cut line of the shape-retaining sheet and the part surrounded by the dividing line of the laminated sheet are integrated with the lid label, the shape-retaining sheet in the area surrounded by the cut line Is cut along the cut line, and the portion of the laminated sheet surrounded by the cut line is cut off along the cut line and remains adhered to the lid label, and an opening is formed in the shape retaining sheet. A take-out opening is formed in the sheet, and the opening of the shape-retaining sheet is formed In which an effect that is easily retrieve the contents from the outlet of the laminated sheet. Moreover, the parting line formed in the laminated sheet is a half cut, and further, the shape-retaining sheet is fixed on the parting line, and for example, an alcohol component contained in the contents penetrates from the parting line. Even if it permeates, it is blocked by the shape-retaining sheet, so that the adhesive strength of the pressure-sensitive adhesive layer of the lid label does not decrease, and the lid label can be prevented from peeling off naturally during product storage It is. In addition, the lid label is provided with a pressure-sensitive adhesive layer that can be re-removed and re-adhered, and the lid label can be peeled off from the shape-retaining sheet at a portion other than the opening of the shape-retaining sheet, and the separated portion Can be re-adhered and can be opened and closed, and the contents can be prevented from drying, absorbing moisture, or mixing foreign matter from the outside.

また、請求項２記載の本発明は、遮蔽層が切目線と分断線とで囲まれた領域に形成されていることにより、当該領域の保型性シートの感圧接着剤層の粘着力を無効にすることができ、積層シートと接着しないために蓋ラベルを一端部側より保型性シートとの間で剥離した際に、分断線に囲まれた部分の積層シートを分断線に沿って切取り易く、また、積層シートの開口部と対向する位置から取出し口まで延出した部分にシワが発生することがなく、美麗な開口部とできる。 Further, in the present invention according to claim 2, since the shielding layer is formed in the region surrounded by the cut line and the dividing line, the adhesive force of the pressure-sensitive adhesive layer of the shape-retaining sheet in the region is increased. When the lid label is peeled from the shape-retaining sheet from one end side so that it cannot be bonded to the laminated sheet, the laminated sheet of the portion surrounded by the dividing line can be cut along the dividing line. It is easy to cut off, and wrinkles are not generated in a portion extending from a position facing the opening of the laminated sheet to the take-out port, and a beautiful opening can be formed.

図１は本発明にかかる包装体の一実施形態を示す斜視図であって、本発明の包装体１は、内容物を密封包装する合成樹脂を主体とする軟質の積層シート２０から形成された包装袋２と、保型性基材層の一方の面に感圧接着剤層が設けられ、積層シート２０より硬質の保型性シート３と、蓋基材層の一方の面に再剥離再接着可能な粘着剤層が設けられた蓋ラベル４を備え、包装袋２の外面に保型性シート３の感圧接着剤層面を当接させて保型性シート３を固着させ、保型性シート３に蓋ラベル４の粘着剤層面を当接させて蓋ラベル４を貼設させた構成である。蓋ラベル４は略矩形状で一端部側に外方に延設した摘み部４０が設けられている。蓋ラベル４には摘み部４０を摘み、蓋ラベル４を剥離した際に、後述するように蓋ラベル４が保型性シート３から剥離されて保型性シート３から完全に分離されることを防ぐためのストッパーとして切刃４１、４１が剥離方向の蓋ラベル４の両端辺から設けられている。また、蓋ラベル４の表面には絵柄、文字や剥離方向を示す記号等が印刷されている。包装袋２は、内容物を密封包装する背貼り熱接着部（図示しない）と上端熱接着部２１と下端熱接着部２２を備え両側部にガセット部２３を有するガセット袋の形態である。なお、包装袋２の形態はピロー袋、三方シール袋、四方シール袋等の任意の形態とすることができるが、内容物の収納量を多くできると共に内容物が取り出しやすいガセット袋が好ましい形態である。 FIG. 1 is a perspective view showing an embodiment of a packaging body according to the present invention. The packaging body 1 of the present invention is formed from a soft laminated sheet 20 mainly composed of a synthetic resin for hermetically packaging the contents. A pressure-sensitive adhesive layer is provided on one side of the packaging bag 2 and the shape-retaining substrate layer, and the shape-retaining layer 3 that is harder than the laminated sheet 20 and re-removed on one side of the lid substrate layer. A lid label 4 provided with an adhesive layer that can be adhered is provided, and the pressure-sensitive adhesive layer surface of the shape-retaining sheet 3 is brought into contact with the outer surface of the packaging bag 2 so that the shape-retaining sheet 3 is fixed. In this configuration, the lid label 4 is attached to the sheet 3 by bringing the pressure-sensitive adhesive layer surface of the lid label 4 into contact therewith. The lid label 4 has a substantially rectangular shape, and is provided with a knob 40 extending outward on one end side. When the lid label 4 is picked by the knob 40 and the lid label 4 is peeled off, the lid label 4 is peeled off from the shape-retaining sheet 3 and completely separated from the shape-retaining sheet 3 as described later. Cutting blades 41 and 41 are provided from both ends of the lid label 4 in the peeling direction as stoppers for prevention. In addition, the surface of the lid label 4 is printed with a picture, characters, a symbol indicating the peeling direction, and the like. The packaging bag 2 is in the form of a gusseted bag having a back-bonded thermal bonding portion (not shown), an upper end thermal bonding portion 21 and a lower end thermal bonding portion 22 for sealing and wrapping the contents and having gusset portions 23 on both sides. In addition, although the form of the packaging bag 2 can be any form such as a pillow bag, a three-side seal bag, a four-side seal bag, etc., a gusset bag that can increase the storage capacity of the contents and easily take out the contents is a preferable form. is there.

図２は図１のＡ−Ａ線断面図であって、包装袋２は、基材層２０ａ、中間層２０ｂ、熱接着性樹脂層２０ｃが順次積層された合成樹脂を主体とする軟質の積層シート２０からなり、積層シート２０の熱接着性樹脂層２０ｃ面同志を対向させて周縁を熱接着し内容物５たとえば、所定枚数載置されたウェットティッシュを密封包装したものである。包装袋２の外面には保型性基材層３１の一方の面に感圧接着剤層３２が設けられた保型性シート３の感圧接着剤層３２面を当接させて保型性シート３が固着されている。さらに蓋基材層４２の一方の面に再剥離再接着可能な粘着剤層４３が設けられた蓋ラベル４が、粘着剤層４３面を保型性シート３の保型性基材層３１に当接させて貼設されている。図１、２は包装体１を使用時の状態、すなわち、蓋ラベル４が上側に位置するように置いた状態を示す。 FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and the packaging bag 2 is a soft laminate mainly composed of a synthetic resin in which a base material layer 20a, an intermediate layer 20b, and a thermal adhesive resin layer 20c are sequentially laminated. The sheet 20 is made of a laminated sheet 20 with the surfaces of the heat-adhesive resin layer 20c facing each other and the peripheral edges thereof are thermally bonded, and the contents 5 such as a predetermined number of wet tissues are hermetically packaged. The outer surface of the packaging bag 2 is brought into contact with the surface of the pressure-sensitive adhesive layer 32 of the mold-holding sheet 3 provided with the pressure-sensitive adhesive layer 32 on one surface of the mold-holding base material layer 31. The sheet 3 is fixed. Further, the lid label 4 provided with the pressure-sensitive adhesive layer 43 that can be re-removed and re-adhered on one surface of the lid base material layer 42 has the surface of the pressure-sensitive adhesive layer 43 as the shape-retaining base material layer 31 of the shape-retaining sheet 3. It is stuck in contact. 1 and 2 show a state where the package 1 is in use, that is, a state where the lid label 4 is placed on the upper side.

図３は本発明にかかる包装体１の蓋部８の構成を示す分解図である。図２、図３を参照しながら蓋部８を詳細に説明する。図２、図３に示すように保型性シート３には、蓋ラベル４が接着された領域内に開口部を形成するための保型性シート３を貫通する切目線３４が閉じた形状、例えば長穴状に形成されている。切目線３４には刃止め（図示しない）が複数設けられている。刃止めは積層シート２０に固着する際に切目線３４で囲まれた部分が脱落することなく、固着できるので刃止めを設けるほうが好ましい。さらに刃止めを設ける位置は開封開始側（図３においては下端熱接着部２２側）を除き開封終了側（上端熱接着部２１側）近傍に設けるほうが容易に開口部を形成できるので好ましい。また、設ける刃止めの数も少ない方がより開口部の形成が容易となり好ましい。 FIG. 3 is an exploded view showing the configuration of the lid 8 of the package 1 according to the present invention. The lid portion 8 will be described in detail with reference to FIGS. As shown in FIGS. 2 and 3, the shape retaining sheet 3 has a shape in which a cut line 34 passing through the shape retaining sheet 3 for forming an opening in the region where the lid label 4 is bonded is closed, For example, it is formed in a long hole shape. The cut line 34 is provided with a plurality of blade stoppers (not shown). When the blade stopper is fixed to the laminated sheet 20, it is preferable to provide the blade stopper because the portion surrounded by the cut line 34 can be fixed without falling off. Further, it is preferable to provide the blade stopper near the opening end side (upper end thermal bonding portion 21 side) except for the opening start side (lower end thermal bonding portion 22 side in FIG. 3), because the opening can be easily formed. Further, it is preferable that the number of blade stoppers to be provided is small because the opening can be formed more easily.

包装袋２を構成する積層シート２０には、保型性シート３の切目線３４で囲まれた領域と対向する領域内で切目線３４より少し内側の位置に積層シート２０側から保型性シート３側に向って積層シート２０を半抜きするハーフカットからなる分断線２４が閉じた形状、例えば長穴状に形成され、この分断線２４で囲まれた部分が取出し口予定部２５となるものである。さらに、保型性シート３の感圧接着剤層３２面には遮蔽層３３が、切目線３４と分断線２４に対応する位置とで囲まれた領域に形成されている。遮蔽層３３は、感圧接着剤層３２の粘着力を無効にすることができ、遮蔽層３３が形成された領域において、保型性シート３は積層シート２０と接着しないために蓋ラベル４を一端部側より保型性シート３との間で剥離した際に、容易に保型性シート３を切目線３４に沿って切取ることができ、さらに分断線２４に囲まれた部分の積層シート２０を分断線２４に沿って切取ることができる。而して後述するように蓋ラベル４を保型性シート３より剥離すると保型性シート３の切目線３４で囲まれた領域と積層シート２０の分断線２４で囲まれた領域が蓋ラベル４と一体となって接着されたままの状態となる。遮断層３３は分断線２４と対向する位置より少し内側にはみだしても許容されるが、はみだし長さは２ｍｍ以内が好ましい。２ｍｍを超えると積層シート２０の分断線２４の内側が保型性シート３と未接着となり、取出し口周縁にシワ、タルミが発生しやすく外観が劣るので好ましくない。また、分断線２４および切目線３４の形状は、円形、楕円形等の曲線状や、長方形、六角形等の角形状やあるいはこれらの組合せ等、任意であるが、分断線２４と切目線３４は相似形であることが好ましい。 The laminated sheet 20 constituting the packaging bag 2 has a shape-retaining sheet from the laminated sheet 20 side at a position slightly inside the cut line 34 in a region facing the region surrounded by the cut line 34 of the shape-retaining sheet 3. A parting line 24 made of a half cut for half-cutting the laminated sheet 20 toward the side 3 is formed in a closed shape, for example, a long hole shape, and a part surrounded by the parting line 24 becomes a planned outlet 25 It is. Further, a shielding layer 33 is formed on the pressure-sensitive adhesive layer 32 surface of the shape-retaining sheet 3 in a region surrounded by a cut line 34 and a position corresponding to the dividing line 24. The shielding layer 33 can invalidate the adhesive force of the pressure-sensitive adhesive layer 32. In the region where the shielding layer 33 is formed, the shape-retaining sheet 3 does not adhere to the laminated sheet 20, so that the lid label 4 is attached. When peeled from the one end side from the shape-retaining sheet 3, the shape-retaining sheet 3 can be easily cut along the cut line 34, and further, a laminated sheet in a portion surrounded by the dividing line 24 20 can be cut along the parting line 24. Thus, as described later, when the lid label 4 is peeled from the mold retaining sheet 3, the region surrounded by the cut line 34 of the mold retaining sheet 3 and the region surrounded by the dividing line 24 of the laminated sheet 20 are the lid label 4. It will be in a state where it is bonded together. The blocking layer 33 is allowed to protrude slightly inward from the position facing the dividing line 24, but the protruding length is preferably within 2 mm. If it exceeds 2 mm, the inside of the parting line 24 of the laminated sheet 20 becomes unbonded with the shape-retaining sheet 3, and wrinkles and tarmi are likely to occur at the periphery of the take-out port, which is not preferable. Further, the shape of the dividing line 24 and the cut line 34 is arbitrary, such as a curved shape such as a circle and an ellipse, a rectangular shape such as a rectangle and a hexagon, or a combination thereof. Are preferably similar.

図３に示すように、分断線２４は、積層シート２０側から保型性シート３側に向かって積層シート２０の熱接着性樹脂層２０ｃと中間層２０ｂを貫通し、基材層２０ａを半抜きするハーフカットである。ハーフカットの深さは、深いほうがよく、基材層２０ａの厚さにおいて非貫通部分の厚さが０．５〜５μｍ以下となるように施すのが好ましい。ハーフカットの深さが基材層２０ａの非貫通部分の厚さが５μｍを超えるとハーフカットの深さが十分でなく蓋ラベル４を剥離した際に、分断線２４に沿って積層シート２０が切取られず取出し口が形成されないことがあり、０．５μｍ未満では、ハーフカットの深さが深すぎて内容物に含有される例えばアルコール成分が多い場合には、アルコール成分が分断線２４から浸透し、蓋ラベル４の粘着剤層４３の接着力低下を招き、製品保管中に蓋ラベル４の自然剥離が発生することがある。なお、本発明における蓋部８とは、保型性シート３が接着された領域の積層シート２０、保型性シート３、蓋ラベル４で構成される部分を指す。 As shown in FIG. 3, the parting line 24 penetrates the thermal adhesive resin layer 20 c and the intermediate layer 20 b of the laminated sheet 20 from the laminated sheet 20 side toward the shape-retaining sheet 3 side, and the base material layer 20 a is halfway Half cut to be removed. The half-cut depth is preferably as deep as possible, and it is preferably applied so that the thickness of the non-penetrating portion is 0.5 to 5 μm or less in the thickness of the base material layer 20a. When the depth of the half cut exceeds 5 μm in the thickness of the non-penetrating portion of the base material layer 20a, the depth of the half cut is not sufficient, and the laminate sheet 20 is cut along the dividing line 24 when the lid label 4 is peeled off. If it is less than 0.5 μm and the depth of the half cut is too deep and the content contains, for example, a large amount of alcohol component, the alcohol component permeates from the breaking line 24. In addition, the adhesive strength of the pressure-sensitive adhesive layer 43 of the lid label 4 may be reduced, and natural peeling of the lid label 4 may occur during product storage.
