Abstract

<P>PROBLEM TO BE SOLVED: To provide a simple package body that can be easily opened by making it possible to easily separate two base materials even though they are in firm contact with each other in the position of an opening section. <P>SOLUTION: A package 1 formed from two packaging base materials 1A and 1B that are heat-sealable has an item storage section 3 containing an item 2. An area around the item storage section 3 is a sealed area 4 where the two packaging base materials 1A and 1B are heat-sealed. The corner of the perimeters of the package 1 has an opening section 5 in which the base materials 1A and 1B are not heat-sealed. The opening section 5 is designed such that the area of the base material 1B is larger than that of the base material 1A and the base material with the larger area (flap 7) juts out beyond the edge of the base material with the smaller area (flap 6). This makes it possible to easily separate the base materials 1A and 1B (flaps 6 and 7) that are in firm contact with each other in the position of the opening section 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、ブリスターパックと呼ばれる包装体に係わり、特に内容物（包装物品）を取り出すに際して開封作業を容易に行うことのできる易開封性包装体とその製造方法に関する。   The present invention relates to a package called a blister pack, and more particularly to an easy-open package that can be easily opened when taking out contents (packaged articles) and a method for manufacturing the same.

従来、スライスハムなどの物品の包装形態として、プラスチックのフィルムやシートから成る基材に、加熱真空若しくは圧空成形等によって凹部をつくり、その凹部内に物品を入れて開口部分を別の基材で覆った後、その周囲をヒートシールしたものが知られる。   Conventionally, as a packaging form for articles such as sliced ham, a concave portion is formed in a base material made of plastic film or sheet by heating vacuum or pressure forming, etc., and the article is put in the concave portion and the opening portion is made of another base material. It is known that the cover is heat sealed after covering.

その種の包装体をブリスターパックと云うが、そのパッケージの外周部には２つの基材を容易に引き剥がし得るよう２つの基材をヒートシールせずに残した開封部が設けられることが通例である。   Such a package is called a blister pack, but the outer periphery of the package is usually provided with an opening that leaves the two substrates without heat sealing so that the two substrates can be easily peeled off. It is.

しかし、係る開封部は２つの基材をヒートシールしていないにも拘らず、基材同士がぴったりと重なり合った状態で密着し合っていることが多く、このため開封に際して開封部における基材同士の端縁を分離できず、開封に時間を要してしまうことがあった。   However, although the opening part is not heat-sealing the two base materials, the base materials are often in close contact with each other so that the base materials in the opening part are open. In some cases, it was impossible to separate the edges of the film, and it took time to open.

そこで、開封部の位置で一方の基材（容器本体）の表面部分に凸部を設けるという提案がされている（例えば、特許文献１）。   Then, the proposal of providing a convex part in the surface part of one base material (container main body) in the position of an opening part is made (for example, patent document 1).

特開２０００−８５８４２号公報JP 2000-85842 A

上記の特許文献１によれば、凸部を設けることで開封開始端における２つの基材（蓋体と容器本体）を指先等で擦ることにより、凸部が滑り止めとなって基材同士の分離が容易に行えるようになる旨記載されているが、基材同士を擦って分離させる方式では、基材の相互間に指先による押圧力が作用して基材同士がより強固に密着してしまう上、一方の基材に対しては凸部の作用で指先が滑ることを防止できても、他方の基材の表面上では指先が滑ってしまうので密着し合った基材を分離するのは容易でない。   According to Patent Document 1 described above, by providing a convex portion and rubbing the two base materials (the lid body and the container body) at the opening start end with a fingertip or the like, the convex portion becomes a non-slip material between the substrates. Although it is described that separation can be easily performed, in the method of separating the substrates by rubbing the substrates, the pressing force by the fingertip acts between the substrates and the substrates are more firmly adhered to each other. In addition, even if the fingertip can be prevented from slipping due to the action of the convex portion on one base material, the fingertip slides on the surface of the other base material, so that the base materials that are in close contact with each other are separated. Is not easy.

本発明は以上のような事情に鑑みて成されたものであり、その目的は開封部の位置で２つの基材が強力に密着し合った状態でも、両者を容易に分離せしめて開封作業を苛立つことなく容易に行うことのできる簡便な包装体とその製造方法を提供することにある。   The present invention has been made in view of the circumstances as described above, and the purpose thereof is to easily separate the two substrates even in a state where the two base materials are in strong contact with each other at the position of the opening portion. An object of the present invention is to provide a simple package that can be easily produced without irritation and a method for producing the same.

本発明は上記目的を達成するため、ヒートシール性を有する２つの包装用基材から成るパッケージ内に包装物品を収容した物品収容部が設けられ、その物品収容部の周囲が２つの包装用基材をヒートシールした封止部とされて成る包装体において、前記パッケージの外周部に２つの包装用基材をヒートシールせずに残した開封部が設けられ、その開封部は一方の包装用基材よりも他方の包装用基材が大きな面積を有して面積の大きい方が小さい方の端縁部分より外方に張り出している構成とされることを特徴とする。   In order to achieve the above object, the present invention is provided with an article storage section for storing a packaged article in a package composed of two packaging substrates having heat-sealability, and the periphery of the article storage section is two packaging bases. In the package formed as a sealing part in which the material is heat-sealed, an opening part is provided on the outer peripheral part of the package without leaving two packaging substrates without heat-sealing, and the opening part is for one of the packagings. The other packaging base material has a larger area than the base material, and the larger area projects outward from the smaller edge portion.

又、以上のような易開封性包装体において、パッケージが多角形状の輪郭を有し、その少なくとも一つの角部分が開封部とされていることを特徴とする。   In the easy-open packaging body as described above, the package has a polygonal outline, and at least one corner of the package is an opening.

更に、ヒートシール性を有する２つの包装用基材から成るパッケージ内に包装物品を収容した物品収容部が設けられ、その物品収容部の周囲が２つの包装用基材をヒートシールした封止部とされると共に、前記パッケージの外周部に２つの包装用基材をヒートシールせずに残した開封部が設けられ、その開封部は一方の包装用基材よりも他方の包装用基材が大きな面積を有して面積の大きい方が小さい方の端縁部分より外方に張り出している構成とされる易開封性包装体を製造する方法であり、２つの包装用基材のそれぞれに前記封止部と成すシール領域と前記開封部と成す非シール領域を設け、一方の包装用基材におけるシール領域内に前記物品収容部と成す凹部領域を設けると共に、他方の包装用基材におけるシール領域内には前記凹部領域の開口部分を覆うための蓋部領域を確保し、而して前記凹部領域内に包装物品を供給した後、その凹部領域の開口部分が前記蓋部領域により覆われるよう２つの包装用基材を重ね合わせて両者のシール領域をヒートシールする工程を有し、前記２つの包装用基材を重ね合わせる前には、両者のシール領域をヒートシールするとき一方の非シール領域より他方の非シール領域の端縁部分が外方に張り出した状態となるよう、一方の非シール領域の端縁部分を欠落せしめることを特徴とする。   Furthermore, an article storage unit that accommodates a packaged article is provided in a package that includes two packaging substrates having heat-sealing properties, and the periphery of the article accommodation unit heat-seals two packaging substrates. In addition, an opening portion is provided on the outer periphery of the package so that the two packaging base materials are left without being heat-sealed. It is a method of manufacturing an easy-open packaging body having a large area and a larger area protruding outward from the smaller edge portion, and each of the two packaging bases A sealing region formed with a sealing portion and a non-sealing region formed with the opening portion are provided, a recessed region formed with the article storage portion is provided in a sealing region in one packaging substrate, and a seal in the other packaging substrate In the area said recess After the lid region for covering the opening portion of the area is secured, and thus the packaging article is supplied into the recess region, the two packaging bases are covered so that the opening portion of the recess region is covered by the lid region. And a step of heat-sealing both sealing regions by overlapping the materials, and before overlapping the two packaging substrates, when the two sealing regions are heat-sealed, the other non-sealing region is replaced by the other non-sealing region. One of the non-sealed region edge portions is missing so that the edge portion of the sealed region protrudes outward.

本発明の易開封性包装体によれば、パッケージの外周部に設けられる開封部を、基材同士の面積を変えて大きい方が小さい方の端縁部分より外方に張り出す構成としていることから、開封に際して基材同士に密着し合うような圧力を加えず、大きい方の端縁部分を小さい方の逆側に引っ張って両者を容易かつ確実に分離させることができる。又、両者の面積の相違によって小さい方の端縁が大きい方の面上に段差として現れるので、その段差部分に指先を引っ掛けることによっても両者を容易に分離することが可能である。   According to the easy-open packaging body of the present invention, the opening portion provided on the outer peripheral portion of the package is configured so that the larger one projects outward from the smaller edge portion by changing the area between the substrates. Therefore, it is possible to easily and surely separate the two by pulling the larger end edge portion to the opposite side of the smaller side without applying a pressure that causes the base materials to closely contact each other at the time of opening. Moreover, since the smaller edge appears as a step on the larger surface due to the difference in area between the two, the two can be easily separated by hooking a fingertip on the step.

このため、分離した両基材の端縁部分を両手の指先により摘んでヒートシールされた封止部を引き剥がして開封を容易に行うことができる。   For this reason, the edge portions of the separated base materials can be picked with the fingertips of both hands, and the heat-sealed sealing portion can be peeled off for easy opening.

又、パッケージが多角形状の輪郭を有し、その少なくとも一つの角部分が開封部とされていることから、パッケージの外周部で開封部のみが大きく張り出すことがなく、このため違和感のない開封部とすることができ、しかも開封開始時点では引き剥がし力を作用させる封止部の面積が小さく、小さな力で開封を開始できるので、開封開始時に指先から基材の端縁部分が滑り抜けてしまったり基材が破断してしまうことがない。   In addition, since the package has a polygonal outline and at least one corner thereof is an opening portion, only the opening portion does not overhang at the outer peripheral portion of the package, so that the opening is not uncomfortable. Since the area of the sealing part where the peeling force acts at the start of opening is small and opening can be started with a small force, the edge portion of the base material slips from the fingertip at the start of opening. The base material is not broken or broken.

更に、本発明の方法によれば、一方の基材に対して開封部とする非シール領域の端縁部分を欠落せしめる工程を加えるだけで上記のような開封部をもつ易開封性包装体を容易に製造することができる。   Furthermore, according to the method of the present invention, an easy-open packaging body having an opening portion as described above can be obtained simply by adding a step of losing the edge portion of the non-sealed region as an opening portion to one of the substrates. It can be manufactured easily.

以下、図面に基づいて本発明を詳しく説明する。図１は、本発明に係る易開封性包装体を示した斜視図、図２は同包装体の平面概略図であり、図３には図２におけるＸ−Ｘ断面を示す。係る包装体はブリスターパックと呼ばれるものであり、これは概して２つの包装用基材１Ａ，１Ｂから成るパッケージ１内に包装物品２を収容し、その周囲をヒートシールして構成される。   Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an easy-open packaging body according to the present invention, FIG. 2 is a schematic plan view of the packaging body, and FIG. 3 shows an XX cross section in FIG. Such a package is called a blister pack, which is generally configured by housing a packaged article 2 in a package 1 composed of two packaging substrates 1A and 1B and heat-sealing the periphery.

２つの基材１Ａ，１Ｂは、ヒートシール性を有する柔軟なフィルム若しくはシートであり、これにはポリエチレン、ポリエチレンテレフタレート、ポリプロピレンなどの単層構造物、あるいはそれらの複合積層物が用いられる。尚、それら基材１Ａ，１Ｂは表面がヒートシール性を有していればよく、ガスバリヤー性を付与するために中間にアルミ層などを形成したものでもよい。   The two base materials 1A and 1B are flexible films or sheets having heat sealing properties, and a single layer structure such as polyethylene, polyethylene terephthalate or polypropylene, or a composite laminate thereof is used for this. The base materials 1A and 1B only have to have a heat-sealing surface, and may be formed with an aluminum layer or the like in the middle in order to provide gas barrier properties.

図１、図２において、３は包装物品を収容した物品収容部であり、この物品収容部３は一方の基材１Ａに加熱真空により凹部領域３Ａを設けると共に、その凹部領域３Ａの開口部分を他方の基材１Ｂで覆うことにより構成され、係る物品収容部３には包装物品２として例えば複数枚の円形スライスハムが収容されている。尚、包装物品２はスライスハムのような定形物（固形物）に限らず、液体や粉末のような不定形物でもよい。   1 and 2, reference numeral 3 denotes an article accommodating portion that accommodates a packaged article. The article accommodating portion 3 is provided with a recessed area 3 </ b> A on one substrate 1 </ b> A by heating vacuum, and an opening portion of the recessed area 3 </ b> A is provided. It is configured by covering with the other base material 1 </ b> B, and a plurality of circular slice hams, for example, are accommodated in the article accommodating portion 3 as the packaged article 2. The packaged article 2 is not limited to a regular product (solid material) such as sliced ham, but may be an irregular product such as a liquid or powder.

又、４は物品収容部３の周囲で２つの基材１Ａ，１Ｂをヒートシールすることにより成る封止部（図２におけるハッチング部分）であり、この封止部４は物品収容部３を囲む扁平な鍔状とされる。   Reference numeral 4 denotes a sealing portion (hatched portion in FIG. 2) formed by heat-sealing the two base materials 1 </ b> A and 1 </ b> B around the article accommodating portion 3, and this sealing portion 4 surrounds the article accommodating portion 3. It has a flat bowl shape.

一方、パッケージ１の外周部には、封止部４の外側縁に連ねて２つの基材１Ａ，１Ｂをヒートシールせずに残した開封部５が設けられる。特に、パッケージ１は多角形（本例において四角形）の輪郭を有する形態とされ、その一つの角部分が三角状の輪郭を有する開封部５とされる。   On the other hand, on the outer peripheral portion of the package 1, an unsealing portion 5 is provided that is connected to the outer edge of the sealing portion 4 and leaves the two base materials 1 </ b> A and 1 </ b> B without heat sealing. In particular, the package 1 is configured to have a polygonal (quadrangle in this example) outline, and one corner of the package 1 is an opening portion 5 having a triangular outline.

図４及び図５から明らかなように、係る開封部５は基材１Ａ，１Ｂの面積を相違させることにより構成される。つまり、開封部５において、基材１Ａ，１Ｂは互いにヒートシールされない別個の片状体６，７とされるが、一方の片状体６（基材１Ａ）よりも他方の片状体７（基材１Ｂ）の面積が大きく設定され、大きい方の片状体７が小さい方の片状体６の端縁部分より外方に張り出す構成とされる。   As is apparent from FIGS. 4 and 5, the unsealing part 5 is configured by making the areas of the base materials 1A and 1B different. That is, in the opening part 5, although the base materials 1A and 1B are made into the separate piece bodies 6 and 7 which are not heat-sealed mutually, the other piece-like body 7 (base material 1A) rather than one piece body 6 (base material 1A). The area of the base material 1B) is set large, and the larger piece 7 is projected outward from the edge portion of the smaller piece 6.

これによれば、包装物品２を取り出す場合、先ず図６のように一方の片状体７の端縁部分を摘み、これを他方の片状体６から離間する方向に引っ張って両者６，７を分離することができる。而して、分離した片状体６，７のそれぞれを両手の指先で摘み、それらを互いに離間する方向に引っ張ってヒートシールされた封止部４を引き剥がすことができる。   According to this, when the packaged article 2 is taken out, first, the edge part of one piece 7 is picked as shown in FIG. Can be separated. Thus, each of the separated pieces 6 and 7 can be picked with the fingertips of both hands and pulled in a direction away from each other to peel off the heat-sealed sealing portion 4.

尚、片状体７の端縁部分を片状体６の逆側に引っ張ったとき、湿気などの影響によって両者６，７が完全に分離しなくても、片状体６の端縁に図７のように指先を引っ掛けて両者６，７を完全分離させることができる。   Note that when the edge portion of the piece 7 is pulled to the opposite side of the piece 6, the edge 6 of the piece 6 can be seen at the edge of the piece 6, even if both 6 and 7 are not completely separated due to the influence of moisture or the like. The fingertips can be hooked as shown in FIG.

次に、上記のような開封部５をもつ包装体の製造方法について説明する。図８は、係る包装体を製造する装置（深絞真空包装機）の一例を示した概略図ある。   Next, the manufacturing method of the package body with the above opening part 5 is demonstrated. FIG. 8 is a schematic view showing an example of an apparatus (deep drawing vacuum packaging machine) for producing such a package.

図８において、Ｒ１，Ｒ２はシート状の基材１Ａ，１Ｂ（包装材料）を巻回したロールであり、一方のロールＲ１から繰り出された基材１Ａには、成形部１１によって包装体の物品収容部と成す上記の凹部領域３Ａが形成される。成形部１１は、加熱真空式のダイ１１Ａ，１１Ｂを具備して構成され、その両ダイ１１Ａ，１１Ｂは基材１Ａを挟んで昇降可能に設けられる。   In FIG. 8, R1 and R2 are rolls obtained by winding sheet-like base materials 1A and 1B (packaging material), and the base material 1A fed out from one roll R1 is provided with a packaged article by the molding unit 11. The above-mentioned recessed area 3 </ b> A that forms the housing portion is formed. The forming unit 11 is configured to include heated vacuum dies 11A and 11B, and both the dies 11A and 11B are provided to be movable up and down with the base material 1A interposed therebetween.

又、１２は基材１Ａの特定部位を欠落させるための分断部である。係る分断部１２は打抜型１２Ａと受枠１２Ｂを備えて構成され、その打抜型１２Ａと受枠１２Ｂは基材１Ａを挟んで昇降可能に設けられる。   Reference numeral 12 denotes a dividing portion for missing a specific portion of the base material 1A. The dividing portion 12 includes a punching die 12A and a receiving frame 12B, and the punching die 12A and the receiving frame 12B are provided so as to be movable up and down across the base material 1A.

１３は成形部１１により形成された凹部領域３Ａ内に包装物品２を供給する物品供給部であり、この物品供給部１３による凹部領域３Ａへの物品供給後には、その開口部分を覆うべく基材１Ａ上にロールＲ２から繰り出された基材１Ｂが重ね合わされる。   Reference numeral 13 denotes an article supply unit that supplies the packaged article 2 into the recessed area 3A formed by the molding section 11, and after the article is supplied to the recessed area 3A by the article supply section 13, a base material is provided to cover the opening. The base material 1B fed out from the roll R2 is overlaid on 1A.

そして、重ね合わされた基材１Ａ，１Ｂは、そのまま接合部１４に送られ、その接合部１４において基材１Ａ，１Ｂ同士が物品収容部３（凹部領域３Ａ）の周囲をヒートシールされるようになっている。尚、接合部１４は一対の加熱板１４Ａ，１４Ｂを備えるヒートシーラであり、その両加熱板１４Ａ，１４Ｂは基材１Ａ，１Ｂを挟んで昇降可能に設けられる。   Then, the overlapped base materials 1A and 1B are sent to the joint portion 14 as they are, so that the base materials 1A and 1B are heat-sealed around the article housing portion 3 (recessed region 3A) in the joint portion 14. It has become. In addition, the junction part 14 is a heat sealer provided with a pair of heating plates 14A and 14B, and both the heating plates 14A and 14B are provided so as to be movable up and down across the base materials 1A and 1B.

特に、本例では、図９のように凹部領域３Ａを形成する基材１Ａに、上記の封止部４と成すシール領域４Ａと、上記の開封部５と成す非シール領域５Ａとを基材１Ａの幅方向に３つずつ設け、その各シール領域４Ａ，・・内に物品収容部と成す凹部領域３Ａを設けるようにしている。又、他方の基材１Ｂにも上記の封止部４と成すシール領域４Ｂと、上記の開封部５と成す非シール領域５Ｂとを基材１Ｂの幅方向に３つずつ設け、その各シール領域４Ｂ，・・内に凹部領域３Ａの開口部分を被覆するに足る蓋部領域３Ｂを確保するようにしている。   In particular, in this example, as shown in FIG. 9, the base material 1 </ b> A that forms the recessed area 3 </ b> A is provided with the sealing area 4 </ b> A that forms the sealing part 4 and the non-sealing area 5 </ b> A that forms the opening part 5. Three each are provided in the width direction of 1A, and a recessed area 3A which is an article accommodating portion is provided in each of the seal areas 4A,. Also, the other base material 1B is provided with three seal regions 4B formed with the sealing portion 4 and three non-seal regions 5B formed with the opening portion 5 in the width direction of the base material 1B, and each of the seals. A lid region 3B sufficient to cover the opening portion of the recessed region 3A is secured in the region 4B.

尚、図９にはシール領域４Ａ，４Ｂや非シール領域５Ａ，５Ｂを明確にするために縦線Ｌ１、横線Ｌ２、及び斜線Ｌ３を示しているが、実際にそれら各線Ｌ１〜Ｌ３を基材１Ａ，１Ｂにして付与する訳でなく、基材１Ａ，１Ｂに設ける各領域３Ａ，３Ｂ，４Ａ，４Ｂ，５Ａ，５Ｂは、ダイ１１Ａ，１１Ｂ、打抜型１２Ａ及び受枠１２Ｂ、並びに加熱板１４Ａ，１４Ｂの大きさやそれらの動作制御等により設定されるものである。   In FIG. 9, vertical lines L1, horizontal lines L2, and diagonal lines L3 are shown in order to clarify the seal areas 4A and 4B and the non-sealed areas 5A and 5B. The regions 3A, 3B, 4A, 4B, 5A, and 5B provided on the base materials 1A and 1B are not provided with 1A and 1B, but die 11A and 11B, punching die 12A and receiving frame 12B, and heating plate 14A, The size is set according to the size of 14B and the operation control thereof.

ここに、本発明では、基材１Ａ，１Ｂのシール領域４Ａ，４Ｂをヒートシールすべく両者１Ａ，１Ｂを重ね合わせる前に、基材１Ａ，１Ｂの何れか一方（本例において１Ａ）に対し、そのシール領域４Ａの外側縁に連なる非シール領域５Ａの端縁部分（図９において黒く塗潰した部分）を図８に示した分断部１２によって欠落せしめ、その欠落部分ａとシール領域４Ａとの間に残される残余部分ｂが上記の片状体６を成すようにしている。   Here, in the present invention, before the sealing regions 4A and 4B of the base materials 1A and 1B are heat-sealed, the two bases 1A and 1B are overlapped with each other with respect to one of the base materials 1A and 1B (1A in this example). The end edge portion of the non-sealed region 5A that is continuous with the outer edge of the seal region 4A (the blacked portion in FIG. 9) is removed by the dividing portion 12 shown in FIG. 8, and the missing portion a and the seal region 4A The remaining portion b left between the two is configured to form the above-described piece-like body 6.

つまり、基材１Ａ，１Ｂを重ね合わせて両者のシール領域４Ａ，４Ｂをヒートシールするとき、非シール領域５Ａの端縁部分が予め欠落部分ａとして欠落させてあることにより、残余部分ｂのみとされる非シール領域５Ａに対し、他方の非シール領域５Ｂの端縁部分が外方に張り出した状態となり、この状態で基材１Ａ，１Ｂのシール領域４Ａ，４Ｂがヒートシールされることにより、非シール領域５Ａの残余部分ｂと非シール領域５Ｂの全体とを片状体６，７とする上記のような開封部５をつくることができる。   That is, when the base materials 1A and 1B are overlapped and the sealing regions 4A and 4B of both are heat-sealed, the edge portion of the non-sealing region 5A is previously missing as the missing portion a, so that only the remaining portion b is obtained. With respect to the non-sealed region 5A, the end portion of the other non-sealed region 5B is projected outward, and in this state, the sealing regions 4A and 4B of the base materials 1A and 1B are heat-sealed. It is possible to make the opening portion 5 as described above, in which the remaining portion b of the non-sealed region 5A and the whole of the non-sealed region 5B are made into pieces 6 and 7.

そして、基材のシール領域４Ａ，４Ｂをヒートシールした後には、図示せぬ切断装置によりシール領域４Ａ，４Ｂと非シール領域５Ｂの外形（縦線Ｌ１及び横線Ｌ２）に沿って基材１Ａ，１Ｂのトリミングが行われ、これによって図１のような包装体が得られる。   And after heat-sealing the sealing regions 4A and 4B of the base material, the base material 1A and the base material 1A along the outer shapes (vertical line L1 and horizontal line L2) of the sealing regions 4A and 4B and the non-sealing region 5B by a cutting device (not shown). The trimming of 1B is performed, and thereby a package as shown in FIG. 1 is obtained.

尚、分断部１２による欠落部分ａの形成は、基材１Ａ，１Ｂ同士を重ね合わせる前であれば凹部領域３Ａの形成前でもその形成後でもよく、更には打抜型１２Ａをダイ１１Ａに取り付けて凹部領域３Ａと同時に形成することもできる。又、打抜型１２Ａによる打ち抜き切除方式に代えて溶断方式を採用することもできる。   Note that the formation of the missing portion a by the dividing portion 12 may be performed before or after the formation of the recessed region 3A as long as the base materials 1A and 1B are overlapped with each other, and further, the punching die 12A is attached to the die 11A. It can also be formed simultaneously with the recessed area 3A. Further, a fusing method may be employed instead of the punching and cutting method using the punching die 12A.

以上、本発明について説明したが、欠落部分Ａは基材１Ａにおける非シール領域５Ａに限らず、例えば基材１Ｂを巻き掛ける図８のローラ１５に切断刃を取り付け、これによって基材１Ｂ側の非シール領域５Ｂの端縁部分を欠落せしめることもできる。   Although the present invention has been described above, the missing portion A is not limited to the non-sealed region 5A in the base material 1A. For example, the cutting blade is attached to the roller 15 in FIG. The edge portion of the non-sealed region 5B can be omitted.
