本願発明は、例えば紙おむつや生理用品（生理用ナプキン）のような物品を複数枚まとめて収容するもので、物品収容状態で略直方体形状となる包装袋に関するものである。 The present invention relates to a packaging bag that accommodates a plurality of articles such as a paper diaper and a sanitary product (sanitary napkin), and has a substantially rectangular parallelepiped shape when the article is accommodated.

例えば、紙おむつは、所定の複数枚（例えば３０〜６０枚）を圧縮した状態で包装袋に収容して店頭販売されている。又、このような包装袋には、持ち運びのための持ち手が形成されている。 For example, a paper diaper is stored over-the-counter by storing it in a packaging bag in a state in which a predetermined plurality of sheets (for example, 30 to 60 sheets) are compressed. Moreover, the handle for carrying is formed in such a packaging bag.

この種の包装袋の公知例として、図７に示すものがある。尚、この図７の包装袋は、特許文献１（特開２００３−９５３３７号公報）に示されるものである。 A known example of this type of packaging bag is shown in FIG. The packaging bag of FIG. 7 is shown in Patent Document 1 (Japanese Patent Laid-Open No. 2003-95337).

図７に示す公知の包装袋は、前面シート部１１と後面シート部１２と該前後両シート部１１，１２に連続する天面シート部１３とを有し、前面シート部１１と後面シート部１２の各側縁部同士をヒートシール（符号１４，１４）するとともに、前面シート部１１と後面シート部１２の各下方部分で底面シート部を形成することにより、包装袋本体１を構成している。 The known packaging bag shown in FIG. 7 has a front sheet portion 11, a rear sheet portion 12, and a top sheet portion 13 continuous to both the front and rear sheet portions 11, 12, and the front sheet portion 11 and the rear sheet portion 12. The side edge portions of each are heat-sealed (reference numerals 14, 14), and the bottom sheet portion is formed at each lower portion of the front sheet portion 11 and the rear sheet portion 12, thereby constituting the packaging bag body 1. .

又、包装袋本体１の上部（前面シート部１１及び後面シート部１２の各上部）には、天面シート部１３を囲繞するようにして小高さのリブ１６，１６が形成されており、この各リブ１６，１６の内面にそれぞれループ状の吊持テープ１７，１７を取付けている。尚、包装袋本体１内への物品収容は、包装袋本体１の底面側から行い、物品収容後に底面シート部を閉塞する。 Further, on the upper portion of the packaging bag body 1 (the upper portions of the front sheet portion 11 and the rear sheet portion 12), ribs 16 and 16 having a small height are formed so as to surround the top sheet portion 13. Loop-like suspension tapes 17 and 17 are attached to the inner surfaces of the ribs 16 and 16, respectively. The articles are stored in the packaging bag body 1 from the bottom surface side of the packaging bag body 1 and the bottom sheet portion is closed after the articles are stored.

図７の包装袋は、包装袋本体１内に物品（複数枚の紙おむつ）を収容した状態（物品包装体）では略直方体形状に膨形し、その物品包装体を自立姿勢で店頭に陳列できるようになっている。又、この物品包装体の購入者は、両吊持テープ１７，１７を握って該物品包装体を持ち運びできる。尚、天面シート部１３に点線表示している部分は、開口形成用のミシン目加工部１８で、該ミシン目加工部１８を引き裂くと物品（紙おむつ）取り出し用の開口を開放できる。 The packaging bag of FIG. 7 can be expanded into a substantially rectangular parallelepiped shape in the state (article packaging body) in which the article (a plurality of paper diapers) is accommodated in the packaging bag body 1, and the article packaging body can be displayed at the storefront in a self-supporting posture. It is like that. Further, the purchaser of the article packaging body can carry the article packaging body by holding both the holding tapes 17 and 17. A portion indicated by a dotted line on the top sheet portion 13 is a perforation processing portion 18 for forming an opening.

ところで、上記した図７の包装袋において、各吊持テープ１７，１７は物品包装体を持ち運ぶために握持するものであるが、この公知の包装袋（特に、各吊持テープ１７，１７）には、次のような欠点があった。 By the way, in the packaging bag of FIG. 7 described above, each of the suspension tapes 17 and 17 is gripped to carry the article package, but this known packaging bag (in particular, each of the suspension tapes 17 and 17). Had the following drawbacks.

(1) 各吊持テープ１７，１７は、常時包装袋本体１から大きくはみ出しているので、陳列状態で見映えが悪い。 (1) Since each of the hanging tapes 17 and 17 protrudes greatly from the packaging bag body 1 at all times, it does not look good in the display state.

(2) 各吊持テープ１７，１７が包装袋本体１に対してビラビラしているので、この物品包装体を陳列棚に出し入れする際に該吊持テープ１７が邪魔になり、ときには該吊持テープ１７が他の物品に引っ掛かるおそれがある。 (2) Since each of the suspension tapes 17 and 17 is fluttering with respect to the packaging bag body 1, the suspension tape 17 becomes an obstacle when the article package is put in and out of the display shelf. There is a possibility that the tape 17 may be caught by other articles.

(3) 吊持テープ１７，１７は、単に物品包装体を持ち運ぶときの持ち手となるだけで、該吊持テープ１７，１７が他の機能（例えば物品包装体をコンパクトにする機能）をもつことがない。 (3) The suspension tapes 17 and 17 merely serve as handles when carrying the article packaging body, and the suspension tapes 17 and 17 have other functions (for example, a function for making the article packaging body compact). There is nothing.

(4) 包装袋本体１内への物品収容作業は包装機で行われるが、その包装工程において各吊持テープ１７，１７が包装機の各部位に引っ掛かり易くなる（補修のための包装作業の中断が多くなる）。又、物品包装完了後の製品搬送時に吊持テープ１７が装置に引っ掛かったり、物品包装体を段ボール箱に梱包する際に吊持テープ１７が段ボール箱からはみ出したりすることもある。 (4) Although the article storage operation in the packaging bag main body 1 is performed by the packaging machine, each of the suspension tapes 17 and 17 is easily caught on each part of the packaging machine in the packaging process (the packaging operation for repair). More interruptions). In addition, the suspension tape 17 may be caught on the apparatus when the product is transported after the product packaging is completed, or the suspension tape 17 may protrude from the cardboard box when the product package is packed in the cardboard box.

本願発明は、上記した従来の包装袋（特に吊持テープ部分）の問題点に鑑み、吊持テープ付きの包装袋であっても、物品包装工程で吊持テープが邪魔にならず、且つ製品陳列状態で吊持テープによる見映えが悪くならないようにでき、しかも吊持テープに持ち手以外の機能をもたせる（例えば製品のコンパクト化に寄与する）ことができるようにした包装袋を提供することを目的としている。 In view of the problems of the above-described conventional packaging bags (particularly the suspension tape portion), the present invention is a product with a suspension tape that does not interfere with the product packaging process even if it is a packaging bag with a suspension tape. To provide a packaging bag that can prevent the appearance of the hanging tape from being deteriorated in a display state, and that allows the hanging tape to have functions other than the handle (for example, contribute to downsizing the product). It is an object.

本願発明は、上記課題を解決するための手段として次の構成を有している。尚、本願発明は、例えば紙おむつや生理用品のような物品を複数枚まとめて収容するのに適した包装袋を対象にしている。 The present invention has the following configuration as means for solving the above problems. The present invention is directed to a packaging bag suitable for storing a plurality of articles such as disposable diapers and sanitary goods.

本願請求項１の発明
本願請求項１の発明の包装袋は、図１〜図６に例示するように、前面シート部１１と後面シート部１２とをそれらの両側縁部でヒートシールするとともに、物品収容状態で略直方体形状に膨形するようになっている。 The invention of claim 1 of the present application The packaging bag of the invention of claim 1 of the present application, as illustrated in FIGS. 1 to 6, heat-seal the front sheet portion 11 and the rear sheet portion 12 at both side edges thereof, It swells into a substantially rectangular parallelepiped shape in the article accommodation state.

そして、この請求項１の包装袋は、前面シート部１１の上端部及び後面シート部１２の上端部に、それぞれ所定小高さ範囲だけ横長袋状に折返してなるテープ挿通部２，２を形成し、該各テープ挿通部２，２内にそれぞれ持ち手となる吊持テープ３，３を挿通させ、該各吊持テープ３，３のそれぞれ両端部３１，３１を、前面シート部１１と後面シート部１２の各側縁部に各ヒートシール１４，１４を共用して熱固着し、各テープ挿通部２，２のそれぞれ長さ方向中央位置に各吊持テープ３，３の一部を露出させる切欠部２２，２２を形成して、該各切欠部２２，２２からそれぞれ吊持テープ３，３の長さ方向中央部付近を引き出し得るようにしていることを特徴としている。 And the packaging bag of this Claim 1 forms in the upper end part of the front sheet | seat part 11, and the upper end part of the rear sheet | seat part 12 the tape insertion parts 2 and 2 each folded in the shape of a horizontally long bag only by the predetermined small height range. The holding tapes 3 and 3 are inserted into the respective tape insertion portions 2 and 2, and both end portions 31 and 31 of the respective holding tapes 3 and 3 are respectively connected to the front sheet portion 11 and the rear sheet. The heat seals 14 and 14 are shared and fixed to the side edges of the portion 12 so that a part of each of the suspension tapes 3 and 3 is exposed at the longitudinal center positions of the tape insertion portions 2 and 2. Cutout portions 22 and 22 are formed, and the lengthwise central portions of the suspension tapes 3 and 3 can be drawn from the cutout portions 22 and 22, respectively.

前面シート部１１及び後面シート部１２には、ポリエチレンやポリプロピレン等の熱溶着するプラスチックシートが使用されており、各吊持テープ３，３にも熱溶着可能なプラスチックテープが使用されている。 The front sheet portion 11 and the rear sheet portion 12 are made of heat-welded plastic sheets such as polyethylene and polypropylene, and the suspension tapes 3 and 3 are also made of heat-weldable plastic tape.

そして、前面シート部１１の上端部及び後面シート部１２の上端部をそれぞれ折返し、所定小高さ（例えば上端から３〜４cmの高さ）だけ下がった位置をそれぞれヒートシールして、該前面シート部１１の上端部及び後面シート部１２の上端部にそれぞれ横長袋状のテープ挿通部２，２を形成している。この各テープ挿通部２，２内には、それぞれ吊持テープ３，３が挿通されているが、この各吊持テープ３，３のそれぞれ両端部３１，３１は、前後両シート部１１，１２の各側縁ヒートシール１４，１４部分を共用して熱固着している。 And the upper end part of the front sheet | seat part 11 and the upper end part of the rear sheet | seat part 12 are turned up, respectively, and the position which fell only predetermined small height (for example, 3-4 cm height from an upper end) is heat-sealed, respectively, This front sheet part 11 and the rear sheet portion 12 are respectively formed with horizontally long bag-like tape insertion portions 2 and 2. Suspension tapes 3 and 3 are respectively inserted into the respective tape insertion portions 2 and 2, and both end portions 31 and 31 of the respective suspension tapes 3 and 3 are arranged at both front and rear seat portions 11 and 12. The side edge heat seals 14 and 14 are shared and thermally fixed.

各吊持テープ３，３の中央部は、各テープ挿通部２，２の中央部に形成している各切欠部２２，２２から露出しており、その各露出部（吊持テープ中央部）３２，３２を握って引き出すことができるようになっている。 The central part of each suspension tape 3, 3 is exposed from each notch 22, 22 formed in the central part of each tape insertion part 2, 2, and each exposed part (suspension tape central part). 32 and 32 can be grasped and pulled out.

ところで、この包装袋は、その包装袋本体内に物品を収容する前（図１の状態）でも、該包装袋本体内に物品を収容した後（図２の状態）でも、各テープ挿通部２，２が伸長している状態（縮んでいない状態）では、各吊持テープ３，３も該テープ挿通部２，２に沿って伸長しており、吊持テープ３の一部がテープ挿通部２の切欠部２２から露出しているものの、吊持テープ３が包装袋本体の外形（前面シート部１１及び後面シート部１２の各上端部）からはみ出すことはない。 By the way, this packaging bag has each tape insertion part 2 before accommodating an article in the packaging bag main body (state of FIG. 1) or after accommodating an article in the packaging bag main body (state of FIG. 2). , 2 is in an extended state (not contracted), the respective suspension tapes 3, 3 are also extended along the tape insertion portions 2, 2, and a part of the suspension tape 3 is part of the tape insertion portion. Although it is exposed from the two notches 22, the hanging tape 3 does not protrude from the outer shape of the packaging bag body (the upper end portions of the front sheet portion 11 and the rear sheet portion 12).

従って、この包装袋内に物品を収容する際に各吊持テープ３，３が邪魔にならず（装置の各部位に引っ掛からない）、又、物品収容後に包装袋が略直方体形状に膨形していても、各吊持テープ３，３は邪魔にならない。 Therefore, the suspension tapes 3 and 3 do not get in the way when the article is accommodated in the packaging bag (does not get caught in each part of the apparatus), and the packaging bag expands into a substantially rectangular parallelepiped shape after the article is accommodated. Even if it is, each suspension tape 3 and 3 does not get in the way.

他方、物品収容状態（図２の状態）において、各吊持テープ３，３の露出部３２，３２を握って引き出すと、図６に示すように、各吊持テープ３，３の各端部３１，３１を固着している袋上部の両側縁部（ヒートシール１４，１４部分）が中央側に引き寄せられて、各吊持テープ３，３の露出部３２，３２が切欠部２２，２２からループ状に引き出され、該両ループ状露出部３２，３２を片手で同時に握持できるようになる。又、このとき各テープ挿通部２，２は長さ方向に縮んで、この包装袋の上部外周部が縮径されるようになっている。 On the other hand, when the exposed portions 32 and 32 of the respective holding tapes 3 and 3 are grasped and pulled out in the article accommodation state (the state shown in FIG. 2), as shown in FIG. Both side edges (heat seals 14 and 14 portions) of the upper part of the bag to which the 31 and 31 are fixed are drawn toward the center side, and the exposed portions 32 and 32 of the respective suspension tapes 3 and 3 are removed from the notches 22 and 22. The loop-shaped exposed portions 32 and 32 can be gripped simultaneously with one hand. At this time, the tape insertion portions 2 and 2 are contracted in the length direction so that the diameter of the upper outer peripheral portion of the packaging bag is reduced.

本願請求項２の発明
本願請求項２の発明は、上記請求項１の包装袋において、各吊持テープ３，３のそれぞれ両端部３１，３１の近傍位置を、前後各シート部１１，１２の両側縁部の各ヒートシール１４，１４とは別にテープ挿通部２，２に対して熱固着させていることを特徴としている。 Invention of Claim 2 of the Present Invention In the invention of claim 2 of the present application, in the packaging bag of the above-mentioned claim 1, the positions near the both ends 31, 31 of the respective suspension tapes 3, 3 It is characterized by being thermally fixed to the tape insertion portions 2 and 2 separately from the heat seals 14 and 14 at both side edges.

この請求項２の発明は、各吊持テープ３，３のそれぞれ両端部３１，３１の固定を確実にするものである。即ち、上記請求項１では、各吊持テープ３，３の両端部３１，３１をそれぞれ前後各シート部１１，１２の各側縁ヒートシール１４，１４部分で共用して熱固着しているが、該各側縁ヒートシール部１４，１４は比較的細幅（例えば１〜１.５mm幅程度）であり、且つ吊持テープ３の端部３１を含めてヒートシールしているので、吊持テープ３の引き出し時に、該吊持テープ３の露出部３２を過剰に強く引っ張ったときには、該側縁ヒートシール部１４による熱固着部分が剥がれる恐れがある。 According to the second aspect of the present invention, the both end portions 31, 31 of the respective suspension tapes 3, 3 are secured. That is, in the above-mentioned claim 1, both end portions 31, 31 of the respective suspension tapes 3, 3 are shared and thermally fixed by the side edge heat seals 14, 14 of the front and rear seat portions 11, 12, respectively. Each of the side edge heat seal portions 14 and 14 has a relatively narrow width (for example, about 1 to 1.5 mm width) and is heat-sealed including the end portion 31 of the suspension tape 3. When the exposed portion 32 of the hanging tape 3 is pulled excessively strongly when the tape 3 is pulled out, there is a possibility that the heat fixing portion by the side edge heat seal portion 14 is peeled off.

そこで、この請求項２の発明では、各吊持テープ３，３の両端部の近傍位置において、上記側縁ヒートシール部１４とは別に、テープ挿通部２に対して熱固着させている。尚、このテープ挿通部２に対する吊持テープ端部近傍の熱固着部分は、１箇所づつでもよいし
複数箇所（２箇所）づつにしてもよい。 In view of this, in the invention according to claim 2, in the vicinity of both ends of each of the suspension tapes 3 and 3, the tape is inserted into the tape insertion portion 2 separately from the side edge heat seal portion 14. In addition, the heat adhering portion in the vicinity of the end portion of the hanging tape with respect to the tape insertion portion 2 may be one by one or a plurality of locations (two locations).

本願請求項１の発明の効果
本願請求項１の発明の包装袋には、次のような効果がある。 Effects of the Invention of Claim 1 The packaging bag of the invention of Claim 1 has the following effects.

即ち、この請求項１の包装袋では、袋上部に形成している各テープ挿通部２，２内にそれぞれ吊持テープ３，３を挿通させているが、この各吊持テープ３，３は、包装袋上部が伸長している状態では該包装袋の外形からはみ出すことなく収まっているので、
(1) この包装袋で物品を包装する包装工程において、各吊持テープ３，３が包装機の各部位に引っ掛かりにくくなり、包装時のトラブルが少なくなって包装作業がスムーズに且つ確実に行える、
(2) 物品包装後の物品包装体（製品）の状態で各吊持テープ３，３が袋外形からはみ出さないので、包装機からの搬送工程、段ボール箱に梱包する梱包工程等においても吊持テープ３が邪魔にならない（搬送工程、梱包工程がスムーズに且つ確実に行える）、
(3) 商品陳列状態で吊持テープ３が袋外形内に収まっているので、見映えがよくなる（従来のループ状の吊持テープでは、袋外に垂れ下がって見映えが悪い）、
等の効果がある。 That is, in the packaging bag according to the first aspect, the suspension tapes 3 and 3 are inserted into the respective tape insertion portions 2 and 2 formed on the upper portion of the bag. In the state where the upper part of the packaging bag is extended, it fits without protruding from the outer shape of the packaging bag,
(1) In the packaging process of packaging articles with this packaging bag, the suspension tapes 3 and 3 are less likely to be caught on each part of the packaging machine, reducing the troubles during packaging and enabling smooth and reliable packaging. ,
(2) Since the suspension tapes 3 and 3 do not protrude from the outer shape of the bag in the state of the article package (product) after the article is packaged, it is also suspended in the transport process from the packaging machine, the packaging process for packaging in the cardboard box, etc. The holding tape 3 does not get in the way (the transport process and packing process can be performed smoothly and reliably),
(3) The appearance of the suspension tape 3 is within the outer shape of the bag in the product display state, so that the appearance is good (the conventional loop-shaped suspension tape hangs down from the bag and looks bad).
There are effects such as.

又、この請求項１の包装袋では、この包装袋で包装した物品包装体を購入して持ち帰る際には各吊持テープ３，３の中央部を引き出すが、このとき包装袋の上部外周部が引き寄せられて縮径するので、物品包装体の上部寄り部分を引き締めてコンパクトにできるという付加価値を付与できる。 In the packaging bag according to claim 1, when the article package packed in this packaging bag is purchased and taken home, the central portion of each of the suspension tapes 3 and 3 is pulled out. Since the diameter is reduced by being drawn, the added value that the portion closer to the upper part of the article packaging body can be tightened to be compact can be provided.

さらに、各吊持テープ３，３のそれぞれ両端部３１，３１は、袋の側縁ヒートシール部１４，１４を共用して袋側縁部に固着させているので、該側縁ヒートシール部１４を吊持テープ端部３１の固定用として有効利用できるという効果もある。 Furthermore, since both end portions 31, 31 of the respective suspension tapes 3, 3 are fixed to the bag side edge portion in common with the side edge heat seal portions 14, 14 of the bag, the side edge heat seal portion 14 is fixed. Can be effectively used for fixing the suspension tape end 31.

本願請求項２の発明の効果
本願請求項２の発明は、上記請求項１の包装袋において、各吊持テープ３，３のそれぞれ両端部３１，３１の近傍位置を、前後各シート部１１，１２の両側縁部の各ヒートシール１４，１４とは別に、テープ挿通部２，２に対して熱固着させている。 Advantages of the Invention of Claim 2 The invention of claim 2 of the present application is the packaging bag of claim 1, wherein the positions near the both end portions 31, 31 of the respective holding tapes 3, 3 are set to the front and rear seat portions 11, 31. In addition to the heat seals 14 and 14 at the side edges of the twelve sides, they are thermally fixed to the tape insertion portions 2 and 2.

上記請求項１のように、吊持テープ端部３１を上記側縁ヒートシール部１４のみで固定したものでは、その吊持テープ端部３１の固着強度にやや難点があるが、この請求項２のように吊持テープ端部３１付近を側縁ヒートシール部１４とは別に熱固着させていると、該吊持テープ端部の固着強度が強固となり、上記請求項１の効果に加えて、吊持テープ３を手荒く引っ張っても吊持テープ端部３１が剥がれることがない、という効果がある。 When the suspension tape end portion 31 is fixed only by the side edge heat seal portion 14 as in the first aspect, there is a slight difficulty in the fixing strength of the suspension tape end portion 31. If the vicinity of the suspension tape end portion 31 is thermally fixed separately from the side edge heat seal portion 14 as described above, the fixing strength of the suspension tape end portion becomes strong, in addition to the effect of claim 1 above, Even if the suspension tape 3 is pulled roughly, there is an effect that the end portion 31 of the suspension tape is not peeled off.

図１〜図６を参照して本願の好適な実施例を説明すると、図１には内部に物品を収容する前の包装袋を示し、図２〜図６には図１の包装袋内に物品４を収容した後の物品包装体を示している。尚、この実施例では、袋内に収容される物品４として紙おむつが採用されているが、該物品４の種類は特に限定するものではない。 A preferred embodiment of the present application will be described with reference to FIGS. 1 to 6. FIG. 1 shows a packaging bag before an article is accommodated therein, and FIGS. 2 to 6 show the packaging bag of FIG. The article packaging body after accommodating the article 4 is shown. In this embodiment, a paper diaper is adopted as the article 4 accommodated in the bag, but the type of the article 4 is not particularly limited.

この実施例の包装袋は、前面シート部１１と後面シート部１２と天面シート部１３を有する１枚物のシートで包装袋本体１を形成している。この種の包装袋のシート材としては、一般にポリエチレンやポリプロピレン等のプラスチックシートが採用されるが、熱溶着可能なシートであれば適宜のもの（例えば不織布シート）が採用可能である。 The packaging bag of this embodiment forms the packaging bag body 1 with a single sheet having a front sheet portion 11, a rear sheet portion 12, and a top sheet portion 13. As a sheet material for this type of packaging bag, a plastic sheet such as polyethylene or polypropylene is generally employed, but any suitable sheet (for example, a nonwoven fabric sheet) can be employed as long as it is a heat-weldable sheet.

図１の包装袋では、前面シート部１１の上端部と後面シート部１２の上端部間に天面シート部１３をガセット折りした状態で挟み込み、それらの両側縁部をヒートシール１４，１４することによって包装袋本体１を形成している。尚、図１の包装袋は、内部に収容される物品の種類、数量等によって大きさ・形状が変わるが、図示例の包装袋では偏平状態での左右幅及び高さがそれぞれ４０〜４５cm程度となっている。又、図１の状態では、底部は物品収容用の開口１５のままとなっているが、包装袋内に物品を収容した後、底部シート部を折畳んで開口１５を閉塞する。 In the packaging bag of FIG. 1, the top sheet portion 13 is sandwiched between the upper end portion of the front sheet portion 11 and the upper end portion of the rear sheet portion 12 in a gusset-folded state, and both side edges thereof are heat-sealed 14 and 14. Thus, the packaging bag body 1 is formed. Although the size and shape of the packaging bag of FIG. 1 vary depending on the type and quantity of articles accommodated therein, the width and height in the flat state in the illustrated packaging bag are about 40 to 45 cm, respectively. It has become. In the state of FIG. 1, the bottom portion remains as the opening 15 for accommodating the article. However, after the article is accommodated in the packaging bag, the bottom sheet portion is folded to close the opening 15.

前面シート部１１及び後面シート部１２の各上端部には、それぞれ横長袋状のテープ挿通部２，２が形成されている。この各テープ挿通部２，２は、図５に拡大図示するように前面シート部１１及び後面シート部１２の各上端部を下方に折返し、その折返し部の上端から所定小高さ（例えば上端から３〜４cmの高さ）だけ下がった位置をそれぞれヒートシール２１，２１して、その上部に横長袋状の中空部を形成したものである。この各テープ挿通部２，２は、前面シート部１１及び後面シート部１２のそれぞれ左右方向の全幅に亘って形成されている。尚、図４及び図５においては、作図上、各シート材の厚さを厚く表示しているが、実際にはフイルム状の薄いものである。 At the upper end portions of the front sheet portion 11 and the rear sheet portion 12, horizontally long bag-like tape insertion portions 2, 2 are formed, respectively. As shown in an enlarged view in FIG. 5, the tape insertion portions 2 and 2 fold back the upper end portions of the front sheet portion 11 and the rear sheet portion 12 downward, and have a predetermined small height (for example, 3 from the upper end). The positions lowered by ˜4 cm (height) are heat-sealed 21 and 21, respectively, and a horizontally long bag-like hollow portion is formed on the top. Each of the tape insertion portions 2 and 2 is formed over the entire width of each of the front sheet portion 11 and the rear sheet portion 12 in the left-right direction. In FIG. 4 and FIG. 5, the thickness of each sheet material is shown to be thick in the drawing, but it is actually a thin film.

この各テープ挿通部２，２内には、それぞれ吊持テープ３，３が挿通されている。この各吊持テープ３，３は、上記包装袋本体１のシート材と熱溶着可能な、例えば高密度ポリエチレンや高密度ポリプロピレン等のプラスチックテープで形成されている。又、この各吊持テープ３，３は、幅が１０〜３０mm、厚さが１００〜３００μｍ程度で伸縮性がほとんどないものが使用されている。 Suspension tapes 3 and 3 are inserted into the tape insertion portions 2 and 2, respectively. Each of the suspension tapes 3 and 3 is formed of a plastic tape such as high-density polyethylene or high-density polypropylene that can be thermally welded to the sheet material of the packaging bag body 1. Each of the suspension tapes 3 and 3 has a width of 10 to 30 mm, a thickness of about 100 to 300 μm, and almost no stretchability.

そして、この各吊持テープ３，３は、それぞれ各テープ挿通部２，２内に挿通させた状態で、該各吊持テープ３，３のそれぞれ両端部３１，３１を上記包装袋本体１の各側縁部において各側縁ヒートシール部１４，１４で共用して熱固着させているとともに、各吊持テープ３，３のそれぞれ両端部３１，３１の近傍位置をそれぞれテープ挿通部２，２に対して別のヒートシール部３３，３４で熱固着させている。吊持テープ３の各端部３１，３１の固着は、包装袋本体１の各側縁ヒートシール部１４，１４だけでも可能であるが、該側縁ヒートシール部１４は比較的固着力が弱いので、吊持テープ端部３１の近傍位置を別にヒートシール（符号３３，３４）して補強することが好ましい。この補強用のヒートシールは、この実施例では各吊持テープ端部３１につきそれぞれ２箇所づつ（円形ヒートシール部３３と直線状ヒートシール部３４）行っているが、１箇所づつでもよい。又、この各ヒートシール部３３，３４の形状は、図示例の円形、直線状のほかに、ハート形やその他のデザイン性のあるものにしてもよい。尚、各ヒートシール部１４，２１，３３，３４は、図４及び図５において黒く塗り潰して表示している。 Then, the respective suspension tapes 3 and 3 are inserted into the respective tape insertion portions 2 and 2, and the respective end portions 31 and 31 of the respective suspension tapes 3 and 3 are respectively connected to the packaging bag body 1. In each side edge portion, the side edge heat seal portions 14, 14 are shared and thermally fixed, and the positions near the both end portions 31, 31 of the respective suspension tapes 3, 3 are respectively connected to the tape insertion portions 2, 2. In contrast, the heat seal portions 33 and 34 are thermally fixed. The end portions 31 and 31 of the hanging tape 3 can be fixed by only the side edge heat seal portions 14 and 14 of the packaging bag body 1, but the side edge heat seal portion 14 has a relatively weak fixing force. Therefore, it is preferable to reinforce the vicinity of the suspension tape end 31 by heat sealing (reference numerals 33 and 34). In this embodiment, the reinforcing heat seal is performed at two places (circular heat seal portion 33 and linear heat seal portion 34) for each suspension tape end portion 31; Further, the shape of each of the heat seal portions 33 and 34 may be a heart shape or other design properties in addition to the circular shape and the straight shape shown in the drawing. In addition, each heat-sealing part 14, 21, 33, 34 is black-painted and displayed in FIG.4 and FIG.5.

各テープ挿通部２，２の中央部には、各吊持テープ３，３の中央部を露出させるための切欠部２２，２２が形成されている。この各切欠部２２，２２の形成範囲は、特に限定するものではないが１０〜１５cm程度が適当である。尚、各側の切欠部２２，２２は、前後に対向する位置にある。 At the central part of each tape insertion part 2, 2, notches 22, 22 are formed for exposing the central part of each of the suspension tapes 3, 3. The formation range of the notches 22 and 22 is not particularly limited, but about 10 to 15 cm is appropriate. In addition, the notch parts 22 of each side are in the position which opposes front and back.

そして、各側の吊持テープ３，３の中央部は、各側の切欠部２２，２２から露出しており、その各露出部３２，３２を握って引き出せば、各吊持テープ３，３の中央部を各切欠部２２，２２からループ状に引き出すことができるようになっている（図６参照）。尚、吊持テープ３には、複数種類の色付きテープを使用し、この包装袋に収容される物品（例えば、紙おむつ）のサイズによって特定の色の吊持テープを使用することで、該吊持テープに収容物品のサイズの識別機能をもたせるようにすることができる。 And the center part of the suspension tapes 3 and 3 of each side is exposed from the notch parts 22 and 22 of each side, and if each exposure part 32 and 32 is grasped and pulled out, each suspension tape 3 and 3 will be exposed. The center portion of each can be pulled out from each of the notches 22 and 22 in a loop shape (see FIG. 6). Note that a plurality of types of colored tapes are used for the suspension tape 3, and a suspension tape of a specific color is used depending on the size of an article (for example, a paper diaper) accommodated in the packaging bag. The tape can be provided with a function for identifying the size of the contained article.

ところで、この包装袋は、その包装袋本体１内に物品４を収容する前（図１の状態）でも、包装袋本体１内に物品４を収容した後（図２〜図６の状態）でも、各テープ挿通部２，２が伸長している状態（縮んでいない状態）では、各吊持テープ３，３も該テープ挿通部２，２に沿って伸長しており、吊持テープ３が包装袋本体１の外形（前面シート部１１及び後面シート部１２の各上端部）からはみ出すことはない。 By the way, this packaging bag either before the article 4 is accommodated in the packaging bag body 1 (state of FIG. 1) or after the article 4 is accommodated in the packaging bag body 1 (state of FIGS. 2 to 6). When the tape insertion portions 2 and 2 are extended (not contracted), the suspension tapes 3 and 3 are also extended along the tape insertion portions 2 and 2. It does not protrude from the outer shape of the packaging bag body 1 (the upper end portions of the front sheet portion 11 and the rear sheet portion 12).

従って、図１の状態（物品収容前の状態）の包装袋では、該包装袋内に物品を収容する際に各吊持テープ３，３が邪魔にならず（吊持テープ３，３が装置の各部位に引っ掛からない）、包装工程がスムーズに且つ確実に行える。又、包装袋内に所定数の物品４を収容すると、図２に示すように包装袋が略直方体形状に膨形するが、その膨形状態になっても、各吊持テープ３，３は包装袋本体１の外形からはみ出さないので、該吊持テープ３，３が邪魔にならず、且つ見映えが悪くならない。 Therefore, in the packaging bag in the state of FIG. 1 (the state before the article is accommodated), the suspension tapes 3 and 3 are not obstructed when the articles are accommodated in the packaging bag (the suspension tapes 3 and 3 are the devices). The packaging process can be carried out smoothly and reliably. Further, when a predetermined number of articles 4 are accommodated in the packaging bag, the packaging bag swells into a substantially rectangular parallelepiped shape as shown in FIG. Since it does not protrude from the outer shape of the packaging bag body 1, the suspension tapes 3 and 3 do not get in the way and the appearance does not deteriorate.

他方、物品収容状態（図２の状態）において、各吊持テープ３，３の露出部３２，３２を握って引き出すと、図６に示すように、各吊持テープ３，３の各端部３１，３１を固着している袋上部の両側縁部（ヒートシール１４，１４部分）が中央側に引き寄せられて、各吊持テープ３，３の露出部３２，３２が切欠部２２，２２からループ状に引き出される。この状態では、該両ループ状露出部３２，３２を片手で同時に握持できる。又、このとき各テープ挿通部２，２は長さ方向に縮んで、この包装袋の上部外周部が縮径され、物品包装体の上部が引き締められてコンパクトになる。 On the other hand, when the exposed portions 32 and 32 of the respective holding tapes 3 and 3 are grasped and pulled out in the article accommodation state (the state shown in FIG. 2), as shown in FIG. Both side edges (heat seals 14 and 14 portions) of the upper part of the bag to which the 31 and 31 are fixed are drawn toward the center side, and the exposed portions 32 and 32 of the respective suspension tapes 3 and 3 are removed from the notches 22 and 22. Pulled out in a loop. In this state, both the loop-shaped exposed portions 32 and 32 can be grasped simultaneously with one hand. At this time, the tape insertion portions 2 and 2 are contracted in the length direction, the diameter of the upper outer peripheral portion of the packaging bag is reduced, and the upper portion of the article package is tightened to be compact.

又、物品包装体の上部を強く引き締めるために、吊持テープ３を強く引くと、吊持テープ端部３１の固着部分に強い引っ張り作用が働くが、この実施例では、吊持テープ３の端部３１の近傍位置において、側縁ヒートシール部１４とは別にヒートシールにより熱固着（符号３３，３４）させているので、吊持テープ端部３１の固着部分が不用意に剥がれることがない。 Further, if the suspension tape 3 is pulled strongly in order to strongly tighten the upper part of the article packaging body, a strong pulling action acts on the fixing portion of the suspension tape end 31. In this embodiment, the end of the suspension tape 3 is used. In the vicinity of the portion 31, heat fixing (reference numerals 33, 34) is performed by heat sealing separately from the side edge heat sealing portion 14, so that the fixing portion of the hanging tape end portion 31 is not inadvertently peeled off.
