Description

本出願は、２０１５年１０月９日に出願された日本特許出願番号２０１５−２０１４９５に基づくもので、ここにその記載内容を援用する。 This application is based on Japanese Patent Application No. 2015-201495 filed on October 9, 2015, and the description thereof is incorporated herein by reference.

本発明は、脱酸素剤、乾燥剤などの雰囲気調整剤が収容された包装袋に関する。 The present invention relates to a packaging bag containing an atmosphere adjusting agent such as an oxygen scavenger and a desiccant.

脱酸素剤や乾燥剤などの雰囲気調整剤は、通常方形の包装袋に収容されて用いられる。この包装袋は、通常ロータリー式三方シール製袋充填包装機を用いて製造される。この包装機では、包装袋を構成する包装材を袋状にし、その袋の残りの一辺（投入辺）の開口部からノズルを挿入し、そのノズルから包装袋内に雰囲気調整剤を投入し、その後その投入辺を溶着しシールして包装袋を形成している。 Atmosphere modifiers such as oxygen scavengers and desiccants are usually housed in a square packaging bag for use. This packaging bag is usually manufactured using a rotary three-way seal bag filling and packaging machine. In this packaging machine, the packaging material constituting the packaging bag is made into a bag shape, a nozzle is inserted from the opening on the remaining side (insertion side) of the bag, and the atmosphere adjusting agent is injected into the packaging bag from the nozzle. After that, the input side is welded and sealed to form a packaging bag.

しかし、上記方法によれば、包装袋の投入辺から投入した粉体状の雰囲気調整剤が、後に溶着される投入辺のシール部にも付着する恐れがある。この場合、その投入辺をシールした際に、雰囲気調整剤が、投入辺の包装材の間のシール部内に入り込むことがある。そうすると、包装袋の外観上好ましくないうえに、シール部に挟まった雰囲気調整剤が外部に漏れる恐れがあることからも好ましくはない。 However, according to the above method, the powdery atmosphere adjusting agent charged from the charging side of the packaging bag may adhere to the sealing portion of the charging side to be welded later. In this case, when the charging side is sealed, the atmosphere adjusting agent may enter the sealing portion between the packaging materials on the charging side. Then, not only the appearance of the packaging bag is not preferable, but also the atmosphere adjusting agent sandwiched between the sealing portions may leak to the outside, which is not preferable.

そこで、包装袋の投入辺を粘着テープで覆うことが提案されている（特許文献１参照）。 Therefore, it has been proposed to cover the loading side of the packaging bag with an adhesive tape (see Patent Document 1).

特開２０１３−１０７６８２号公報Japanese Unexamined Patent Publication No. 2013-107682

しかしながら、この方法によれば、包装材とは別部材の粘着テープを用意し、その粘着テープを包装袋の投入辺に貼り付ける工程が必要となるため、その分コストがかかり、製造工程も煩雑になる。さらに、殺菌などのため包装袋を高温で熱処理する必要がある場合には、温度によっては粘着テープの溶剤が溶け出すことも想定され、使用可能温度が限定されてしまう。 However, according to this method, it is necessary to prepare an adhesive tape which is a member different from the packaging material and attach the adhesive tape to the loading side of the packaging bag, which is costly and complicated. become. Further, when it is necessary to heat-treat the packaging bag at a high temperature for sterilization or the like, it is assumed that the solvent of the adhesive tape may melt out depending on the temperature, and the usable temperature is limited.

本出願は、かかる点に鑑みてなされたものであり、脱酸素剤や乾燥剤などの雰囲気調整剤が投入部から漏れることがなく、さらにコストの低減、製造の簡略化を図ることができ、高温下でも使用可能な包装袋を提供することができる。 This application was made in view of this point, and the atmosphere adjusting agent such as oxygen scavenger and desiccant does not leak from the charging part, and the cost can be further reduced and the manufacturing can be simplified. It is possible to provide a packaging bag that can be used even at high temperatures.

本発明者らは、包装袋の投入辺における表裏の包装材の端部の位置をずらし、突出した一の端部を他の端部の外側に折り返して溶着することにより、上記課題を解決できることを見出し、本発明を完成するに至った。

Further, the following embodiments are examples for explaining the present invention, and the present invention is not limited to this embodiment.

図１（ａ）は、本実施の形態における包装袋１の構成の概略を示す正面図であり、図１（ｂ）は、包装袋１の側面図である。なお、本願明細書において、包装袋１の雰囲気調整剤の投入辺側（図１、図２の上側）を上側とする。本願明細書において、「雰囲気調整剤」とは、脱酸素剤や乾燥剤など周囲の雰囲気を調整するものである。脱酸素剤の代表的な製品としては、エージレス（登録商標、三菱ガス化学株式会社製）が知られている。 FIG. 1A is a front view showing an outline of the configuration of the packaging bag 1 in the present embodiment, and FIG. 1B is a side view of the packaging bag 1. In the specification of the present application, the charging side (upper side of FIGS. 1 and 2) of the atmosphere adjusting agent of the packaging bag 1 is referred to as the upper side. In the specification of the present application, the "atmosphere adjusting agent" is used to adjust the surrounding atmosphere such as an oxygen scavenger and a desiccant. Ageless (registered trademark, manufactured by Mitsubishi Gas Chemical Company, Inc.) is known as a typical product of oxygen scavenger.

図１（ａ）、（ｂ）に示すように包装袋１は、例えば方形の袋状に形成され、内部に雰囲気調整剤Ａが収容されている。 As shown in FIGS. 1A and 1B, the packaging bag 1 is formed in the shape of, for example, a square bag, and contains the atmosphere adjusting agent A inside.

包装袋１の下辺部２０は、包装材３０を折り返すことにより形成されている。すなわち、下辺部２０には、不連続な切れ目がなく、その下縁が例えば円弧状に湾曲している。 The lower side portion 20 of the packaging bag 1 is formed by folding back the packaging material 30. That is, the lower side portion 20 has no discontinuous cut, and its lower edge is curved in an arc shape, for example.

包装袋１の左辺部２１及び右辺部２２は、表面３１と裏面３２の包装材３０同士を溶着することにより形成されている。 The left side portion 21 and the right side portion 22 of the packaging bag 1 are formed by welding the packaging materials 30 of the front surface 31 and the back surface 32 to each other.

雰囲気調整剤Ａが投入された投入部としての上辺部２３は、図２に示すように包装材３０の表面３１と裏面３２のそれぞれの端部３１ａ、３２ａの位置が上下にずれており、その相対的に突出した裏面側の端部３２ａが表面側の端部３１ａの外側に折り返され溶着されて形成されている。 As shown in FIG. 2, the upper side portion 23 as the charging portion into which the atmosphere adjusting agent A is charged has the positions of the end portions 31a and 32a of the front surface 31 and the back surface 32 of the packaging material 30 displaced vertically. The relatively protruding end portion 32a on the back surface side is formed by being folded back and welded to the outside of the end portion 31a on the front surface side.

包装材３０は、１枚のフィルムを用いることも出来るし、２枚以上のフィルムを重ね合せた状態（シール部以外は接着していない）で用いることもできる。上記フィルムには単層フィルムや、異なる材質からなる２層以上の多層フィルムを用いることができる。図２には包装材３０の表面３１及び裏面３２のそれぞれに、２枚の２層フィルム３３、３４を重ね合せて用いる場合を示している。外側フィルム３３は２層構造を有し、第１の材料としての例えばポリエチレンからなる内層４０と、第２の材料としての例えばポリエチレンテレフタレートやナイロン等の第１の材料より融点の高い材料からなる外層４１を有している。第１の材料である内層４０は、ヒートシール性を有する材料を使用することができる。ヒートシール性を有する材料とは、例えば、低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、直鎖状（線状）低密度ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体、アイオノマー樹脂、エチレン−アクリル酸共重合体、エチレン−アクリル酸エチル共重合体、エチレン−メタクリル酸共重合体、メタロセン触媒を使用して重合したエチレン−α・オレフィン共重合体、ポリプロピレン、エチレン−メタクリル酸メチル共重合体、エチレン−プロピレン共重合体、メチルペンテンポリマー、ポリブテンポリマー、ポリエチレンまたはポリプロピレン等のポリオレフィン系樹脂をアクリル酸、メタクリル酸、マレイン酸、無水マレイン酸、フマール酸、イタコン酸等の不飽和カルボン酸で変性した酸変性ポリオレフィン樹脂、ポリ酢酸ビニル系樹脂、ポリ（メタ）アクリル系樹脂、ポリ塩化ビニル系樹脂等の樹脂からなる１種以上のフィルムもしくはシートまたは塗布膜などを使用することができる。 As the packaging material 30, one film may be used, or two or more films may be laminated (other than the sealing portion is not adhered). As the film, a single-layer film or a multilayer film having two or more layers made of different materials can be used. FIG. 2 shows a case where two two-layer films 33 and 34 are superposed on each of the front surface 31 and the back surface 32 of the packaging material 30. The outer film 33 has a two-layer structure, and is an inner layer 40 made of, for example, polyethylene as a first material, and an outer layer made of a material having a higher melting point than the first material such as polyethylene terephthalate or nylon as a second material. Has 41. As the inner layer 40, which is the first material, a material having a heat-sealing property can be used. Materials having heat-sealing properties include, for example, low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear (linear) low-density polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ionomer resin, and ethylene-acrylic. Acid copolymers, ethylene-ethyl acrylate copolymers, ethylene-methacrylic acid copolymers, ethylene-α-olefin copolymers polymerized using a metallocene catalyst, polypropylene, ethylene-methyl methacrylate copolymers, Polyylene-propylene copolymers, methylpentene polymers, polybutene polymers, polyethylene or polypropylene and other polyolefin resins were modified with unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid and itaconic acid. One or more films or sheets or coating films made of resins such as acid-modified polyolefin resins, polyvinyl acetate resins, poly (meth) acrylic resins, and polyvinyl chloride resins can be used.

内側フィルム３４は、第３の材料としての例えば紙や不織布を有する層４２と第１の材料と同じくヒートシール性を有する材料である層４３を有している。本実施の形態では、外側フィルム３３が内側フィルム３４より長く、包装材３０の裏面３２の端部３２ａは、外側フィルム３３だけで形成されている。包装材３０の裏面３２の端部３２ａが、表面３１の端部３１ａ側に折り返され、互いに材質が異なる端部３２ａの内層４０の内側面と端部３１ａの外層４１の外側面が溶着されている。 The inner film 34 has a layer 42 having, for example, paper or a non-woven fabric as a third material, and a layer 43 which is a material having heat sealability like the first material. In the present embodiment, the outer film 33 is longer than the inner film 34, and the end portion 32a of the back surface 32 of the packaging material 30 is formed only by the outer film 33. The end portion 32a of the back surface 32 of the packaging material 30 is folded back toward the end portion 31a of the front surface 31, and the inner side surface of the inner layer 40 of the end portion 32a made of different materials and the outer surface of the outer layer 41 of the end portion 31a are welded together. There is.

図２では、端部３２ａは外側フィルム３３のみから構成されているが、端部３２ａは、外側フィルム３３と内側フィルム３４の両方を含む一枚の多層フィルムであってもよい。つまり、端部３２ａは、２枚の２層フィルムからなる外側フィルム３３と内側フィルム３４から構成されているのではなく、１枚の４層フィルムから構成されていてもよい。図３は、端部３２ａが１枚の４層フィルムから構成されている場合を示している。この場合は、端部３２ａの層４３の内側面と端部３１ａの層４１の外側面が溶着されている In FIG. 2, the end portion 32a is composed of only the outer film 33, but the end portion 32a may be a single multilayer film including both the outer film 33 and the inner film 34. That is, the end portion 32a may be composed of one four-layer film instead of the outer film 33 and the inner film 34 composed of two two-layer films. FIG. 3 shows a case where the end portion 32a is composed of one four-layer film. In this case, the inner side surface of the layer 43 of the end portion 32a and the outer surface of the layer 41 of the end portion 31a are welded.

ここで、包装袋１の製造方法の一例について説明する。先ず図４に示すように長方形状の包装材３０が折り返される。このとき、包装材３０は、中央で折り返されず、最上部に裏面３２の端部３２ａとなる折り返し部が残るように折り返される。すなわち、包装材３０の中央線から表面３１側（図４の下側）に折り返し線をずらした状態で表面３１側を裏面３２側に折り返し、裏面３２の最上部に端部３２ａを露出させる。こうして下端に下辺部２０が形成される。なお、このとき、包装材３０の内側には、予め内層フィルム３４が配置されている。次に、図５に示すように左右端部が溶着され、左辺部２１と右辺部２２が形成される。こうして、上辺部２３が開口し他の三辺（下辺部２０、左辺部２１及び右辺部２２）が封鎖された袋が形成される。次に、図６に示すように例えばノズルＢが上辺部２３の開口から挿入され、袋の内部に雰囲気調整剤Ａが噴出され、充填される。その後、図７に示すように上辺部２３の裏面３２の端部３２ａが表面３１の端部３１ａの外側に折り返され、端部３２ａと端部３１ａが溶着される。こうして、図１及び図２に示すような、４辺が封鎖され、内部に雰囲気調整剤Ａが収容された包装袋１が完成する。 Here, an example of the manufacturing method of the packaging bag 1 will be described. First, as shown in FIG. 4, the rectangular packaging material 30 is folded back. At this time, the packaging material 30 is not folded back at the center, but is folded back so that a folded-back portion that becomes an end portion 32a of the back surface 32 remains at the uppermost portion. That is, the front surface 31 side is folded back to the back surface 32 side in a state where the folding line is shifted from the center line of the packaging material 30 to the front surface 31 side (lower side in FIG. 4), and the end portion 32a is exposed at the uppermost portion of the back surface 32. In this way, the lower side portion 20 is formed at the lower end. At this time, the inner layer film 34 is arranged in advance inside the packaging material 30. Next, as shown in FIG. 5, the left and right end portions are welded to form the left side portion 21 and the right side portion 22. In this way, a bag is formed in which the upper side portion 23 is opened and the other three sides (lower side portion 20, left side portion 21 and right side portion 22) are closed. Next, as shown in FIG. 6, for example, the nozzle B is inserted through the opening of the upper side portion 23, and the atmosphere adjusting agent A is ejected and filled inside the bag. After that, as shown in FIG. 7, the end portion 32a of the back surface 32 of the upper side portion 23 is folded back to the outside of the end portion 31a of the front surface 31, and the end portion 32a and the end portion 31a are welded. In this way, as shown in FIGS. 1 and 2, the four sides are closed, and the packaging bag 1 in which the atmosphere adjusting agent A is contained is completed.

本実施の形態によれば、雰囲気調整剤Ａが投入された投入部としての上辺部２３が、表面３１と裏面３２の包装材３０の端部３１ａ、３２ａの位置がずれており、その相対的に突出した一の端部３２ａが他の端部３１ａの外側に折り返され溶着されて形成されているので、内部の雰囲気調整剤Ａが上辺部２３から漏れることがない。そして、一の端部３２ａを他の端部３１ａの外側に折り返して溶着したので、粘着テープのような別部材も必要としないので、コストもかからず、また製造工程も簡略化できる。さらに粘着テープを使用しないため、高温下でも使用可能になる。 According to the present embodiment, the upper side portion 23 as the charging portion into which the atmosphere adjusting agent A is charged is displaced from the positions of the ends 31a and 32a of the packaging material 30 on the front surface 31 and the back surface 32, and the relative positions thereof. Since one end portion 32a protruding from the surface is folded and welded to the outside of the other end portion 31a, the internal atmosphere adjusting agent A does not leak from the upper side portion 23. Since one end portion 32a is folded back to the outside of the other end portion 31a and welded, a separate member such as an adhesive tape is not required, so that the cost is low and the manufacturing process can be simplified. Furthermore, since no adhesive tape is used, it can be used even at high temperatures.

さらに、包装材３０の裏面３２の端部３２ａが表面３１の端部３１ａの外側に折り返されて溶着しているので、上辺部２３が、表面側から、裏面３２の端部３２ａ、表面３１の端部３１ａ及び裏面３２の端部３２ａの３重になっており、その部分の強度が上がる。この結果、包装袋１が雰囲気調整剤の投入部から破損することや、変形することが抑制され、内部の雰囲気調整剤Ａが漏れることを防止できる。また、包装袋１を開封し難くなるので、誤って開封し、内部の雰囲気調整剤Ａが誤飲されるようなことも抑制できる。 Further, since the end portion 32a of the back surface 32 of the packaging material 30 is folded back to the outside of the end portion 31a of the front surface 31 and welded, the upper side portion 23 is from the front surface side to the end portion 32a of the back surface 32 and the front surface 31. The end portion 31a and the end portion 32a of the back surface 32 are tripled, and the strength of that portion is increased. As a result, it is possible to prevent the packaging bag 1 from being damaged or deformed from the charging portion of the atmosphere adjusting agent, and to prevent the internal atmosphere adjusting agent A from leaking. Further, since it becomes difficult to open the packaging bag 1, it is possible to prevent the packaging bag 1 from being accidentally opened and the internal atmosphere adjusting agent A being accidentally swallowed.

また、包装３０の裏面３２の端部３２ａを表面３１の端部３１ａ側に折り返しているので、その際に他の部材を挟み込んで、当該部材を包装袋１に取り付けることができる。例えば図８に示すように包装袋１と併用する酸素検知剤や湿気検知剤などの検知剤５０を、端部３２ａと端部３１ａとの間に挟み込んで、包装袋１に取り付けることができる。 Further, since the end portion 32a of the back surface 32 of the package 30 is folded back toward the end portion 31a side of the front surface 31, another member can be sandwiched at that time and the member can be attached to the packaging bag 1. For example, as shown in FIG. 8, a detection agent 50 such as an oxygen detection agent or a humidity detection agent used in combination with the packaging bag 1 can be sandwiched between the end portion 32a and the end portion 31a and attached to the packaging bag 1.

また、本実施の形態によれば、包装袋１の投入部である上辺部２３と対向する対向部となる下辺部２０が、包装材３０が折り返されて形成されている。これにより、対向する上辺部２３と下辺部２０の両方の端縁に切れ目がなく円弧状に湾曲しているので、例えば包装袋１を、袋の開口からその中に入れるなどの狭いところを通すときに包装袋１が引っ掛からず、取扱い性が向上する。 Further, according to the present embodiment, the packaging material 30 is formed by folding back the lower side portion 20 which is the facing portion facing the upper side portion 23 which is the charging portion of the packaging bag 1. As a result, both the end edges of the upper side portion 23 and the lower side portion 20 facing each other are curved in an arc shape without a break, so that the packaging bag 1 is passed through a narrow place such as being inserted into the bag through the opening of the bag. Sometimes the packaging bag 1 does not get caught, improving handleability.

以上、添付図面を参照しながら本発明の好ましい実施の形態について説明したが、本発明はかかる例に限定されない。当業者であれば、特許請求の範囲に記載された思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、それらについても当然に本発明の技術的範囲に属するものと了解される。 Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to such examples.
