Description

本発明は、カップ入り焼きそば等のように、麺に熱湯を注いで一定時間放置した後、湯切りを行う容器に使用する湯切り孔付き蓋材に関する。 The present invention relates to a lid material with a hot water cut hole used for a container for hot water cutting after pouring hot water into noodles and leaving it for a certain period of time, such as a cupped fried noodle.

従来、カップ入り焼きそば等は、発泡ポリスチレン等からなる容器に収納し、外蓋と内蓋が少なくとも部分的に剥離可能に積層されるとともに内蓋の摘み部の近傍に剥離開始切目が形成され、摘み部を掴んで部分的に外蓋を剥離させることにより内蓋に湯切り孔を形成できるようにした蓋材を熱接着して取り付けた構成のものが知られている。   Conventionally, cupped fried noodles are stored in a container made of expanded polystyrene or the like, and an outer lid and an inner lid are laminated so as to be at least partially peelable, and a peeling start cut is formed in the vicinity of the knob portion of the inner lid, There is known a configuration in which a lid member that is capable of forming a hot water hole in the inner lid by gripping the knob and partially peeling the outer lid is attached by thermal bonding.

しかしながら、上記のように、外蓋と内蓋が少なくとも部分的に剥離可能に積層されるとともに内蓋の摘み部の近傍に剥離開始切目が形成された蓋材を発泡ポリスチレン製等の容器に熱接着部にて接着して取り付けられた包装体において、蓋材に形成された剥離開始切目が熱接着部の外端に位置するように取り付けられるのが正規であり、その場合には、摘み部を掴んで蓋材を容器から剥離することにより、剥離開始切目の箇所から外蓋を内蓋から剥離させて内蓋に湯切り孔を形成することができるものである。   However, as described above, an outer lid and an inner lid are laminated at least partially so as to be peelable, and a lid material in which a peeling start cut is formed in the vicinity of the knob of the inner lid is heated in a container made of foamed polystyrene or the like. In the package attached by bonding at the bonding part, it is normal that the peeling start cut formed in the lid material is attached so as to be located at the outer end of the heat bonding part. The lid is peeled from the container by gripping the outer lid, and the outer lid can be peeled off from the inner lid from the location where the peeling starts, so that a hot water cutting hole can be formed in the inner lid.

しかしながら、内蓋の摘み部の近傍に剥離開始切目を形成した蓋材では、蓋材を製造する工程にて蓋材の打ち抜かれた周縁に対する剥離開始切目の位置に多少のずれが生じるとともに、蓋材を容器に取り付ける際に蓋材と容器の相対的な位置に多少のずれが生じるため、容器に蓋材を熱接着した際に、剥離開始切目の位置が熱接着部の外端に位置せずに熱接着部の外端より外側ないしは内側にずれることがある。蓋材が容器に熱接着された状態で剥離開始切目の位置が熱接着部の外端より外側にずれた場合は剥離開始切目の箇所から蓋材を外蓋と内蓋に分離できるが、剥離開始切目の位置が熱接着部の内側にずれた場合には、剥離開始切目より外側の蓋材の熱接着性樹脂層が容器に接着するため、摘み部を掴んで蓋材を容器から剥離させる際に、容器の発泡ポリスチレン等の表面層が蓋材の内面に接着した状態で蓋材が容器から剥離してしまい、剥離開始切目の箇所にて蓋材を外蓋と内蓋に剥離させて分離することができず、内蓋に湯切り孔が形成できないという問題が発生する欠点を有している。   However, in the lid material in which the peeling start cut is formed in the vicinity of the knob portion of the inner lid, there is a slight shift in the position of the peeling start cut with respect to the peripheral edge of the lid material in the process of manufacturing the lid material, and the lid When the material is attached to the container, the relative position between the lid and the container will be slightly shifted.When the lid is thermally bonded to the container, the position of the peeling start cut is located at the outer edge of the thermal bonding part. Without shifting from the outer end of the heat bonding part to the outside or inside. When the position of the peeling start cut is shifted outside the outer edge of the thermal bonding part with the lid material thermally bonded to the container, the lid material can be separated from the location of the peeling start cut into the outer lid and the inner lid. When the position of the starting cut is shifted to the inside of the thermal bonding part, the thermal adhesive resin layer of the lid material outside the peeling starting cut is adhered to the container, so the grip part is grasped and the lid material is peeled off from the container. At that time, the lid material peels off from the container with the surface layer of foamed polystyrene or the like of the container adhered to the inner surface of the lid material, and the lid material is peeled off from the outer lid and the inner lid at the point where the peeling starts. It has a drawback that it cannot be separated and a hot water hole cannot be formed in the inner lid.

本発明の目的は、発泡ポリスチレン製等の容器に取り付けられる蓋材において、蓋材を容器に取り付けた際に蓋材と容器の相対的な位置に多少ずれが生じた場合でも、蓋材を容器から剥離させることにより、剥離開始切目の箇所から蓋材を外蓋と内蓋に分離させて、内蓋に確実に湯切り孔を形成することができるようにした湯切り孔付き蓋材を提供することである。   An object of the present invention is to cover a lid attached to a container made of expanded polystyrene or the like, even when the relative position between the lid and the container is slightly shifted when the lid is attached to the container. The lid material with a hot water hole is provided by separating the lid material into an outer lid and an inner lid from the location where the peeling starts, so that the hot water hole can be reliably formed in the inner lid. It is to be.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

外蓋と内蓋が離型層を介して剥離可能に積層された構成からなり外周縁の少なくとも１か所に外方に突出する摘み部を有する形状の蓋材であって、離型層が摘み部に隣接する領域に形成され、内蓋には、離型層に対向する領域に複数の湯切り孔切目が形成されるとともに摘み部の内側に所定間隔を有する少なくとも２本の剥離開始切目が形成された構成とすることにより、蓋材を容器に熱接着する際に蓋材に形成された内側の剥離開始切目が熱接着部の外端に位置するように設定して熱接着した場合に、蓋材の周縁と剥離開始切目のずれないしは蓋材と容器の相対的なずれの発生により、蓋材の内側の剥離開始切目が熱接着部の外端より内側にずれることがあっても、摘み部を掴んで蓋材を容器から剥離する際に、外側の剥離開始切目の箇所から外蓋と内蓋を剥離させて分離できるので確実に湯切り孔を形成することができる。   An outer lid and an inner lid have a structure in which the outer lid and the inner lid are laminated so as to be peelable through a release layer, and the lid has a shape having a knob protruding outward at at least one location on the outer peripheral edge. Formed in a region adjacent to the knob, and the inner lid has a plurality of hot water cuts formed in a region facing the release layer, and at least two peeling start cuts having a predetermined interval inside the knob When the lid is thermally bonded to the container by setting it so that the inner peeling start cut formed on the lid is positioned at the outer end of the thermal bonding portion. In addition, even if the peeling start cut inside the lid is displaced inward from the outer end of the thermal bonding part due to the deviation of the peripheral edge of the lid and the peeling start cut or the relative deviation between the lid and the container, When gripping the knob and peeling the lid from the container, Since it can be separated by peeling the al outer lid and the inner lid can be formed reliably hot cut holes.

外蓋と内蓋が離型層を介して剥離可能に積層された構成からなり外周縁の少なくとも１か所に外方に突出する摘み部を有する形状の蓋材であって、離型層が摘み部に隣接する領域に形成され、内蓋には、離型層に対向する領域に複数の湯切り孔切目が形成されるとともに摘み部の内側に所定間隔を有する略平行な２本の剥離開始切目が形成され、２本の剥離開始切目に挟まれた領域において内蓋が除去されている構成とすることにより、蓋材を容器に熱接着した際に、上記の理由で、蓋材の内側の剥離開始切目が熱接着部の外端より内側に位置するように熱接着された場合でも、蓋材の内側の剥離開始切目と外側の剥離開始切目に挟まれた部分の内蓋が除去されているので、蓋材の内側の剥離開始切目より外側の部分にて容器に接着することがなく、摘み部を掴んで蓋材を容器から剥離する際に、内側の剥離開始切目の箇所から蓋材を外蓋と内蓋に剥離させて分離できるので、内蓋に確実に湯切り孔を形成することが可能となる。   An outer lid and an inner lid have a structure in which the outer lid and the inner lid are laminated so as to be peelable through a release layer, and the lid has a shape having a knob protruding outward at at least one location on the outer peripheral edge. Formed in a region adjacent to the knob, the inner lid is formed with a plurality of hot water cuts in a region facing the release layer, and two substantially parallel peelings having a predetermined interval inside the knob By forming the start cut and removing the inner lid in the region between the two peeling start cuts, when the lid is thermally bonded to the container, for the above reason, Even when heat-bonded so that the inner peeling start cut is positioned inside the outer edge of the thermal bonding part, the inner lid of the part sandwiched between the inner peeling start cut and the outer peeling start cut is removed. Because it is, adhere to the container at the part outside the peeling start cut inside the lid When removing the lid from the container by grasping the knob, the lid can be separated from the outer lid and the inner lid by separating them from the inner peeling start cut point, so that a hot water cut-off hole is securely formed in the inner lid. It becomes possible to form.

上記湯切り孔付き蓋材において、離型層が、剥離開始切目の近傍領域においてベタ離型層とされ且つその他の領域において網点離型層とされている構成とすることにより、蓋材を容器から剥離する際に、内側ないしは外側の剥離開始切目の近傍において内蓋と外蓋が容易に剥離するので、蓋材を容器から剥離させることにより外蓋と内蓋に剥離させて分離することが容易となる。また、湯切り孔切目が形成された領域は網点離型層とされているので、外蓋と内蓋の剥離強度がやや強くなり、湯切り孔切目に囲まれた部分は外蓋に接着した状態で抜き取られ、内蓋に確実に湯切り孔を形成させることができる。   In the lid member with a hot water cut hole, the release layer is configured as a solid release layer in a region in the vicinity of the separation start cut and a halftone dot release layer in the other region. When peeling from the container, the inner lid and the outer lid are easily peeled in the vicinity of the inner or outer peeling start cut line, so that the outer lid and the inner lid are separated by separating the lid from the container. Becomes easy. In addition, since the area where the hot water cut hole cut is formed is a halftone dot release layer, the peel strength between the outer lid and the inner cover is slightly increased, and the portion surrounded by the hot water cut hole cut is bonded to the outer cover. In such a state, the hot water hole is reliably formed in the inner lid.

上記湯切り孔付き蓋材において、蓋材には前記摘み部と対向する周縁に他の摘み部が形成され、外蓋には、摘み部と蓋材の中心を結ぶ線と直交方向の蓋材の周縁に達する外蓋切目が形成され、剥離開始切目と外蓋切目と蓋材の周縁に囲まれた領域に離型層が形成された構成とすることにより、摘み部を掴んで蓋材を容器から剥離すると、離型層が形成された領域にて外蓋が内蓋から簡単に剥離するとともに外蓋切目から切り取られ、湯切り孔が形成された内蓋が容器に接着した状態となる。この蓋材を容器に熱接着して取り付けた容器はインスタント焼きそば等の容器に適しており、他の摘み部を掴んで蓋材を半分程度容器から剥離させて開口を形成し、開口から容器に熱湯を注いで一定時間放置した後に、上記のように湯切り孔を形成させて簡単に湯切りすることができる。   In the lid member with a hot water cut-out hole, the lid member is formed with another knob part on the periphery facing the knob part, and the outer cover has a lid member perpendicular to the line connecting the knob part and the center of the lid member. The outer cover cut reaching the periphery of the cover is formed, and the release layer is formed in the region surrounded by the peeling start cut, the outer cover cut, and the periphery of the cover material. When peeled from the container, the outer lid is easily peeled off from the inner lid in the region where the release layer is formed, and is cut off from the outer lid cut line, and the inner lid with the hot water cut hole is adhered to the container. . A container attached by thermally bonding the lid material to the container is suitable for containers such as instant fried noodles.The other gripping part is grasped and the lid material is peeled off about half of the container to form an opening. After pouring hot water and allowing it to stand for a certain period of time, it is possible to easily form hot water by forming a hot water hole as described above.

上記湯切り孔つき蓋材において、外蓋が紙層単体ないしはプラスチックフィルムと紙層の積層体からなり、内蓋がポリエチレン層とアルミニウム箔と熱接着性樹脂層の積層体からなる構成とすることにより、蓋材の内面からのハーフカットにより内蓋に剥離開始切目、湯切り孔切目を形成するのが容易となる。また、アルミニウム箔を積層しているので蓋材のカールが少なくなり容器に蓋を熱接着する際の作業性がよくなる。 In the lid material with hot water cut holes, the outer lid is composed of a single paper layer or a laminate of a plastic film and a paper layer, and the inner lid is composed of a laminate of a polyethylene layer, an aluminum foil, and a heat-adhesive resin layer. Thus, it becomes easy to form a peeling start cut and a hot water cut hole cut in the inner lid by a half cut from the inner surface of the lid member. Moreover, since the aluminum foil is laminated, curling of the lid material is reduced, and workability when the lid is thermally bonded to the container is improved.

Grab the other knob 2 'and peel the lid material about half from the container, and pour hot water into the container. After leaving for a certain period of time, the grip portion 2 of the lid member thermally bonded to the container is grasped and peeled off, and the outer lid 10 is peeled off from the inner lid 20 from the position of the peeling start cut 3a or the peeling start cut 3b and separated. By cutting the outer lid cut line 6, a hot water cutting hole is formed in the inner lid 20 to perform hot water cutting.

本発明の第２実施形態の蓋材の底面図及び断面図は図３及び図４に示すとおりであり、蓋材の形状は、図３に示すように、略円形状であって周縁に外方に突出する摘み部２が形成されるとともに摘み部２と対向する周縁に他の摘み部２’が形成されており、内蓋２０の摘み部２の内側には一定間隔をおいて略平行な２本の剥離開始切目３ａ’と剥離開始切目３ｂ’が形成されて、２本の剥離開始切目３ａ’と剥離開始切目３ｂ’に挟まれた部分の内蓋２０が取り除かれており、内蓋２０の剥離開始切目３ａ’及び剥離開始切目３ｂ’より蓋材の中央側に複数の湯切り孔切目４が形成され、外蓋１０には、蓋材の中央部において摘み部２と蓋材の中心を結ぶ線に直交方向の蓋材の周縁に達する外蓋切目６が形成されている。外蓋１０の下面に形成される剥離層は第１実施形態と同じであり、外蓋切目６の機能も第１実施形態と同じである。 The bottom view and cross-sectional view of the lid material of the second embodiment of the present invention are as shown in FIGS. 3 and 4 , and the shape of the lid material is substantially circular as shown in FIG. A knob part 2 protruding in the direction is formed, and another knob part 2 ′ is formed on the peripheral edge facing the knob part 2, and is substantially parallel to the inner side of the knob part 2 of the inner lid 20 at a constant interval. The two peeling start cuts 3a ′ and the peeling start cut 3b ′ are formed, and the inner lid 20 between the two peeling start cuts 3a ′ and the peeling start cut 3b ′ is removed. A plurality of hot water cut holes 4 are formed on the center side of the lid material from the peeling start cut 3a ′ and the peeling start cut 3b ′ of the lid 20, and the outer lid 10 has a knob 2 and a lid material at the center of the lid material. An outer lid cut 6 is formed that reaches the peripheral edge of the lid member in the direction orthogonal to the line connecting the centers of the two. The release layer formed on the lower surface of the outer lid 10 is the same as that of the first embodiment , and the function of the outer lid cut 6 is the same as that of the first embodiment .

第２実施形態の断面構成は、図４に示すとおりである。第２実施形態の蓋材を熱接着により取り付けた容器は第１実施形態と同様にインスタント焼きそば等の容器に適しており、使用方法も第１実施形態と同じである。第１、２実施形態において、剥離開始切目３ａと剥離開始切目３ｂの間隔、及び剥離開始切目３ａ’と剥離開始切目３ｂ’の間隔は１〜５ｍｍとするのが好ましい。また、網点離型層１１ａを、湯切り孔切目４の中央部に対向する領域に網点離型層１１ａを形成しない構成としてもよい。 The cross-sectional configuration of the second embodiment is as shown in FIG. Container the lid was attached by thermal bonding of the second embodiment is suitable for a container for instant noodles, etc. as in the first embodiment, the method used is also the same as the first embodiment. In 1st, 2nd embodiment , it is preferable that the space | interval of peeling start cut 3a and peeling start cut 3b and the space | interval of peeling start cut 3a 'and peeling start cut 3b' shall be 1-5 mm. Moreover, it is good also as a structure which does not form the halftone dot release layer 11a in the area | region which opposes the center part of the hot water cut hole notch 4 for the halftone dot release layer 11a.

第２実施形態の蓋材を発泡ポリスチレン等からなる容器９に熱接着した状態は図５に示すとおりであり、正規の状態では熱接着部８の外端が内側の剥離開始切目３ａ’の位置にくるように熱接着される。図５に示す状態から蓋材の摘み部２を掴んで容器９から剥離することにより、剥離開始切目３ａの箇所から蓋材が外蓋１０と内蓋２０に剥離して分離されるとともに、湯切り孔切目４に囲まれた部分が外蓋１０に接着した状態で抜き取られて湯切り孔７が形成され、外蓋切目６にて外蓋１０が切り取られ、図６に示す状態となる。図５に示す容器はインスタント焼きそば等に適したものであり、使用方法は、摘み部２’を掴んで蓋材を容器から半分程度剥離させて容器に熱湯を注入して一定時間放置した後に、上記のように蓋材の摘み部２を掴んで剥離させて内蓋２０に湯切り孔を形成させることができるものである。 The state in which the lid material of the second embodiment is thermally bonded to the container 9 made of expanded polystyrene or the like is as shown in FIG. 5 , and in the normal state, the outer end of the thermal bonding portion 8 is the position of the inner peeling start cut 3a ′. It is heat-bonded so that 5 , the lid material is separated from the outer lid 10 and the inner lid 20 and separated from the location of the separation start cut 3a by grasping the lid knob 2 and separating from the container 9. A portion surrounded by the cut hole cut 4 is removed in a state where it is adhered to the outer lid 10 to form a hot water cut hole 7, and the outer lid 10 is cut off by the outer lid cut 6, resulting in the state shown in FIG. 6 . The container shown in FIG. 5 is suitable for instant fried noodles, etc., and the method of use is to hold the knob 2 ', peel the lid material about half from the container, inject hot water into the container and leave it for a certain period of time. As described above, the lid 2 can be gripped and peeled to form a hot water hole in the inner lid 20.

第２実施形態の蓋材を容器９に熱接着した状態において、図示しないが、蓋材と容器の相対的な位置にずれが生じて、内側の剥離開始切目３ａ’の位置が、蓋材を容器に接着するための熱接着部８の外端よりも内側にずれた場合においても、剥離開始切目３ａ’と剥離開始切目３ｂ’に挟まれた部分の内蓋２０が取り除かれているので、蓋材の摘み部２を掴んで容器９から剥離することにより、剥離開始切目３ａ’の箇所から蓋材が外蓋１０と内蓋２０に剥離させて分離されるとともに、湯切り孔切目４に囲まれた部分が外蓋１０に接着した状態で抜き取られて湯切り孔７が形成され、外蓋切目６にて外蓋１０が切り取られた状態となる。したがって、蓋材と容器の相対的な位置がずれた状態で熱接着された場合でも確実に湯切り孔を形成できるものである。 In the state where the lid material of the second embodiment is thermally bonded to the container 9, although not shown, the relative position between the lid material and the container is shifted, and the position of the inner peeling start cut 3a ′ is Even when the inner lid 20 of the part sandwiched between the peeling start cut 3a ′ and the peeling start cut 3b ′ is removed even in the case where it shifts inward from the outer end of the thermal bonding part 8 for bonding to the container, By grasping the grip portion 2 of the lid material and peeling it from the container 9, the lid material is peeled off from the location of the peeling start cut 3 a ′ and separated from the outer lid 10 and the inner lid 20, and the hot water cut hole cut 4 is formed. The enclosed portion is pulled out in a state of being bonded to the outer lid 10 to form the hot water cutting hole 7, and the outer lid 10 is cut out at the outer lid cut line 6. Therefore, even when the lid member and the container are heat-bonded in a state where the relative positions of the container and the container are shifted, it is possible to reliably form the hot water hole.

第１、第２実施形態の蓋材において２本の剥離開始切目と湯切り孔切目と外蓋切目を形成する方法は、外蓋と内蓋を離型層を介して剥離可能に積層した後に、少なくとも２本の剥離開始切目と湯切り孔切目は内蓋の内面側からのハーフカットにより、外蓋切目は外蓋の外面側からのハーフカットにより、それぞれ内蓋ないしは外蓋を貫通する状態で形成されるものである。第２実施形態のように、摘み部の内側に形成された２本の剥離開始切目に挟まれた部分の内蓋を除去する方法としては、外蓋と内蓋を離型層を介して剥離可能に積層したロール状の積層体を作製し、ハーフカット用のロータリーダイにより積層体の内面から所定位置に一定間隔をおいて２本の剥離開始切目を積層体の流れ方向に連続して形成しながら、２本の剥離開始切目に挟まれた内蓋を帯状に除去することにより形成することができる。 The method of forming two peeling start cuts, a hot water cut hole cut, and an outer lid cut in the lid materials of the first and second embodiments is performed after the outer lid and the inner lid are detachably laminated via a release layer. , At least two peeling start cuts and hot water cut holes cut through the inner lid or outer lid by half-cutting from the inner side of the inner lid, and the outer lid cuts by half-cut from the outer side of the outer lid. Is formed. As in the second embodiment , as a method of removing the inner lid between the two peeling start cuts formed inside the knob, the outer lid and the inner lid are peeled off through the release layer. A roll-shaped laminated body that can be laminated is produced, and two peeling start cuts are continuously formed in the flow direction of the laminated body at predetermined intervals from the inner surface of the laminated body by a rotary die for half cut. However, it can be formed by removing the inner lid sandwiched between the two peeling start cuts in a strip shape.

離型層を形成するための樹脂としては、硝化綿、ポリアミド樹脂、ポリエステル樹脂、アクリル樹脂、ブチラール樹脂、塩化ビニル−酢酸ビニル共重合体、エチレン−酢酸ビニル共重合体等の単体ないしは混合物が使用できる。必要により少量のシリコーン等を添加してもよい。離型層は上記の樹脂からなるインキを使用して紙面にグラビア印刷等により印刷することにより形成される。ベタ離型層はベタ版を使用した印刷により、網点離型層は網点面積率が１０〜４０％の網点状にエッチングされた印刷版を使用して印刷することにより形成される。ベタ離型層とポリエチレン層との界面では容易に剥離するが、網点離型層とポリエチレン層との界面ではやや剥離強度が強くなる。ベタ離型層が形成された剥離開始切目の領域では外蓋と内蓋を容易に剥離させることができる。なお、図１、図３においては、網点離型層の形成領域に円形の湯切り孔切目を配置したものとしているが、円形の湯切り孔切目の中央部と対向する領域に網点離型層を形成しないようにしてもよく、その場合は、外蓋を剥がす際に、円形の湯切り孔切目に囲まれた部分の内蓋と外蓋のラミ強度が大きくなるので、より確実に一体となって剥がし取ることができ、湯切り孔を形成することができる。また、図１においては、剥離開始切目３ａ、３ｂとその近傍をベタ離型層としているが、剥離開始切目３ａの両端部に対応する位置を網点離型層とするかもしくは剥離層を設けないようにしても良く、その場合剥離開始切目３ａの両端部から内蓋が不用意に剥がれることがなく好ましい。 As the resin for forming the release layer, nitrified cotton, polyamide resin, polyester resin, acrylic resin, butyral resin, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer, etc. are used alone or as a mixture. it can. If necessary, a small amount of silicone or the like may be added. The release layer is formed by printing on the paper surface by gravure printing or the like using the ink made of the above resin. The solid release layer is formed by printing using a solid plate, and the halftone dot release layer is formed by printing using a printing plate etched into a halftone dot shape having a dot area ratio of 10 to 40%. Peeling easily occurs at the interface between the solid release layer and the polyethylene layer, but the peel strength is slightly increased at the interface between the halftone release layer and the polyethylene layer. The outer lid and the inner lid can be easily peeled in the region of the peeling start cut where the solid release layer is formed. In FIG. 1 and FIG. 3, it is assumed that a circular cut hole cut is arranged in the formation area of the halftone dot release layer, but the halftone dot cut is formed in a region facing the center of the circular cut hole cut. The mold layer may not be formed. In that case, when the outer lid is peeled off, the laminating strength of the inner lid and the outer lid in the portion surrounded by the circular hot water cut hole notch is increased. It can be peeled off as a unit, and a hot water hole can be formed. In FIG. 1 , the peeling start cuts 3a and 3b and the vicinity thereof are solid release layers, but the positions corresponding to both ends of the peeling start cuts 3a are halftone dot release layers or provided with a release layer. In this case, the inner lid is preferably not peeled off from both ends of the peeling start cut 3a.
