（包装容器）
図１に、本発明の実施形態に係るゲーベルトップ型包装容器１００（以下、単に包装容器１００という）の斜視図を示し、図２には、折返し板１０８及び側面板１１１ｂの正面図及び断面図を示す。なお、以下の説明では、便宜上、包装容器１００を正立させた際の上下方向を上下と定める。 (Packaging container)
FIG. 1 shows a perspective view of a Goebel top type packaging container 100 (hereinafter, simply referred to as a packaging container 100) according to an embodiment of the present invention, and FIG. 2 shows a front view and a cross-sectional view of a folded plate 108 and a side plate 111b. Is shown. In the following description, for convenience, the vertical direction when the packaging container 100 is upright is defined as vertical.

包装容器１００は、シート材を加工したブランク１１０を箱型に折曲げ、端部を重ね合わせてシールして形成される。包装容器１００は、正立時に上部となる頂部１０１と、側面となる胴部１０２と、下部となる底部１０３とを含む。頂部１０１は、２つの屋根板１０６（１０６ａ、１０６ｂ）と、屋根板１０６の間に折込まれる折込み板１０７および折返し板１０８とを含む。それぞれの屋根板１０６の下端には、側面板１１１ａが連接される。また、それぞれの折返し板１０８の下端には、側面板１１１ｂが連接されている。側面板１１１ａ、１１１ｂには、一例として、包装容器１００を正立させた際の左右方向である幅方向に、破断強度を弱化させた脆弱部１０５が胴部１０２を一周するように形成される。なお、脆弱部１０５は形成しなくてもよい。 The packaging container 100 is formed by bending a blank 110, which is a processed sheet material, into a box shape, overlapping the ends thereof, and sealing the blank 110. The packaging container 100 includes a top portion 101 which is an upper portion when standing upright, a body portion 102 which is a side surface, and a bottom portion 103 which is a lower portion. The top 101 includes two roof plates 106 (106a, 106b) and a folding plate 107 and a folding plate 108 that are folded between the roof plates 106. A side plate 111a is connected to the lower end of each roof plate 106. Further, a side plate 111b is connected to the lower end of each folded plate 108. As an example, the side plates 111a and 111b are formed with a fragile portion 105 having a weakened breaking strength so as to go around the body portion 102 in the width direction, which is the left-right direction when the packaging container 100 is upright. .. The fragile portion 105 does not have to be formed.

図２に示すように、折返し板１０８と側面板１１１ｂとの境界線１２５上には罫線１２１が形成されている。罫線１２１は、境界線１２５の長さ方向中央において所定長さ設けられていない。以下では、罫線１２１が所定長さ設けられていない箇所を便宜上、分断部１１６という。分断部１１６は、２つの折返し板１０８及び側面板１１１ｂの境界線１２５上それぞれに設けることが好ましいが、一方側だけに設けてもよい。罫線１２１は周知の技術により形成でき、例えば、ローラー等によりブランク１１０を両面から押圧することにより形成することができる。 As shown in FIG. 2, a ruled line 121 is formed on the boundary line 125 between the folded plate 108 and the side plate 111b. The ruled line 121 is not provided with a predetermined length at the center of the boundary line 125 in the length direction. In the following, the portion where the ruled line 121 is not provided with a predetermined length is referred to as a dividing portion 116 for convenience. The dividing portion 116 is preferably provided on the boundary line 125 of the two folded plates 108 and the side plate 111b, respectively, but may be provided on only one side. The ruled line 121 can be formed by a well-known technique, for example, by pressing the blank 110 from both sides with a roller or the like.

図２の断面図に示すように、分断部１１６によって、折返し板１０８及び側面板１１１ｂの間に曲率半径の小さい角部１２０が形成されず、当該位置は緩やかに湾曲した円弧形状となる。 As shown in the cross-sectional view of FIG. 2, the divided portion 116 does not form a corner portion 120 having a small radius of curvature between the folded plate 108 and the side plate 111b, and the position has a gently curved arc shape.

（ブランク）
図３に、包装容器１００の素材となるブランクの一例であるブランク１１０の平面図を示す。ブランク１１０は、頂部１０１を構成する屋根板１０６ａ、１０６ｂ、折込み板１０７および折返し板１０８と、胴部１０２を構成する側面板１１１ａ、１１１ｂと、底部１０３を構成する底面板１１２と、端部に形成されたシール部１１３とを有する。折返し板１０８と折返し板１０８の下端に連接された側面板１１１ｂとの境界線１２５上の長さ方向中央には、罫線１２１が所定長さ設けられていない分断部１１６が形成される。側面板１１１ａ、１１１ｂには、脆弱部１０５が胴部１０２を一周するように形成される。 (blank)
FIG. 3 shows a plan view of a blank 110, which is an example of a blank used as a material for the packaging container 100. The blank 110 includes roof plates 106a and 106b, folding plates 107 and folding plates 108 forming the top 101, side plates 111a and 111b forming the body 102, bottom plates 112 forming the bottom 103, and ends. It has a formed seal portion 113. A dividing portion 116 in which the ruled line 121 is not provided with a predetermined length is formed at the center in the length direction on the boundary line 125 between the folded plate 108 and the side plate 111b connected to the lower end of the folded plate 108. The fragile portions 105 are formed on the side plates 111a and 111b so as to go around the body portion 102.

分断部１１６の幅は、７ｍｍ以上が好ましく、側壁部１１１ｂの幅方向全てにわたって形成してもよい。分断部１１６の幅が７ｍｍに満たないと、包装容器１００を折り畳む際に、分断部１１６に指が収まりきれずに効果が十分に得られないためである。 The width of the divided portion 116 is preferably 7 mm or more, and may be formed over the entire width direction of the side wall portion 111b. This is because if the width of the divided portion 116 is less than 7 mm, the fingers cannot fit in the divided portion 116 when the packaging container 100 is folded, and the effect cannot be sufficiently obtained.

（シート材）
図４に、ブランク１１０に用いられる積層体であるシート材２００の積層構造及び脆弱部１０５の構造の例を模式的に表す断面図を示す。シート材２００は、包装容器１の外方から内方に向かって順に、印刷層２０８／熱可塑性樹脂層２０１／紙基材層２０２／接着樹脂層２０３／バリア層２０４／接着層２０５／シーラント層２０６を有する。 (Sheet material)
FIG. 4 shows a cross-sectional view schematically showing an example of the laminated structure of the sheet material 200, which is the laminated body used for the blank 110, and the structure of the fragile portion 105. The sheet material 200 is formed in the order of printing layer 208 / thermoplastic resin layer 201 / paper base material layer 202 / adhesive resin layer 203 / barrier layer 204 / adhesive layer 205 / sealant layer from the outside to the inside of the packaging container 1. Has 206.

熱可塑性樹脂層２０１は、低密度ポリエチレン樹脂（ＬＤＰＥ）や直鎖状低密度ポリエチレン樹脂（ＬＬＤＰＥ）等を用いて、押出しラミネーション等により紙基材層２０２上に層形成することができる。 The thermoplastic resin layer 201 can be formed on the paper base material layer 202 by extrusion lamination or the like using a low density polyethylene resin (LDPE), a linear low density polyethylene resin (LLDPE), or the like.

熱可塑性樹脂層２０１の外方には、印刷層２０８を設けて絵柄や商品情報を表示してもよい。印刷層２０８は、周知のインキを用いてグラビア印刷やオフセット印刷等の方法により形成することができる。熱可塑性樹脂層２０１にコロナ処理等の易接着処理を行って、印刷層２０８との密着性を高めることができる。印刷層２０８の外方に耐摩耗性向上または表面加飾性向上のためにオーバーコート層を設けても良い。 A print layer 208 may be provided on the outside of the thermoplastic resin layer 201 to display a pattern or product information. The print layer 208 can be formed by a method such as gravure printing or offset printing using a well-known ink. The thermoplastic resin layer 201 can be subjected to an easy-adhesion treatment such as a corona treatment to improve the adhesion to the printing layer 208. An overcoat layer may be provided on the outer side of the print layer 208 in order to improve wear resistance or surface decoration.

紙基材層２０２には、ミルクカートン原紙等の板紙を用いることができる。坪量及び密度は、容器の容量やデザインにより適宜選択可能である。例えば、坪量２００ｇ／ｍ２以上５００ｇ／ｍ２以下、密度０．６ｇ／ｃｍ３以上１．１ｇ／ｃｍ３以下のものを用いることができる。 As the paper base material layer 202, a paperboard such as a milk carton base paper can be used. The basis weight and density can be appropriately selected depending on the capacity and design of the container. For example, those having a basis weight of 200 g / m 2 or more and 500 g / m 2 or less and a density of 0.6 g / cm 3 or more and 1.1 g / cm 3 or less can be used.

接着樹脂層２０３は、紙基材層２０２と基材フィルム層２０４とを接着する機能を有するポリオレフィン系樹脂からなる層である。具体的には、高密度ポリエチレン樹脂（ＨＤＰＥ）、中密度ポリエチレン樹脂（ＭＤＰＥ）、ＬＤＰＥ、ＬＬＤＰＥ、エチレン・メタクリル酸共重合体（ＥＭＡＡ）、エチレン・アクリル酸共重合体（ＥＡＡ）、アイオノマー、ポリプロピレン（ＰＰ）等を用いることができる。接着強度を高めるために、紙基材層２０２やバリア層２０４の表面に、コロナ処理、オゾン処理、アンカーコート等を行ってもよい。または、接着樹脂層２０３に替えて、ドライラミネート接着剤等を用いた接着層としても良い。厚さは、１０μｍ以上６０μｍ以下が好ましい。１０μｍ以上とすることで、十分な接着強度を得ることができる。 The adhesive resin layer 203 is a layer made of a polyolefin resin having a function of adhering the paper base material layer 202 and the base film layer 204. Specifically, high density polyethylene resin (HDPE), medium density polyethylene resin (MDPE), LDPE, LLDPE, ethylene / methacrylic acid copolymer (EMAA), ethylene / acrylic acid copolymer (EAA), ionomer, polypropylene. (PP) or the like can be used. In order to increase the adhesive strength, the surfaces of the paper base material layer 202 and the barrier layer 204 may be subjected to corona treatment, ozone treatment, anchor coating or the like. Alternatively, instead of the adhesive resin layer 203, an adhesive layer using a dry laminate adhesive or the like may be used. The thickness is preferably 10 μm or more and 60 μm or less. Sufficient adhesive strength can be obtained by setting the thickness to 10 μm or more.

バリア層２０４は、アルミニウム等の金属、シリカ、アルミナ等を蒸着した蒸着層２０４ｂと基材フィルム２０４ａとを含む蒸着フィルム、又はアルミニウム等の金属箔２０４ｃを基材フィルム２０４ａにドライラミネートした積層フィルムを用いることができる。蒸着層２０４ｂの厚さは、５ｎｍ以上１００ｎｍ以下とすることができ、基材フィルム２０４ａとして、ポリエチレンテレフタレートを用いる場合は、厚さは６μｍ以上２５μｍ以下とすることができる。 The barrier layer 204 is a vapor-deposited film containing a vapor-deposited layer 204b on which a metal such as aluminum, silica, alumina or the like is vapor-deposited and a base film 204a, or a laminated film in which a metal foil 204c such as aluminum is dry-laminated on the base film 204a. Can be used. The thickness of the thin-film deposition layer 204b can be 5 nm or more and 100 nm or less, and when polyethylene terephthalate is used as the base film 204a, the thickness can be 6 μm or more and 25 μm or less.

バリア層２０４として、ポリエチレンテレフタレートフィルムにバリアコーティングを施したバリアコーティングポリエチレンテレフタレートフィルムや、ＥＶＯＨなどのバリア材料からなるバリア性フィルムを用いることができる。金属箔２０４ｃとしてアルミニウム箔を、基材フィルム２０４ａとしてのポリエチレンテレフタレートフィルムにドライラミネートしたフィルムを用いる場合は、アルミニウム箔の厚さは５μｍ以上１５μｍ以下とすることができ、ポリエチレンテレフタレート層の厚さは６μｍ以上２５μｍ以下とすることができる。後述するレーザー光による加工のしやすさの点で、ポリエチレンテレフタレート層の厚さは１２μｍ程度とすることが好ましい。 As the barrier layer 204, a barrier-coated polyethylene terephthalate film obtained by applying a barrier coating to a polyethylene terephthalate film, or a barrier film made of a barrier material such as EVOH can be used. When a film obtained by dry-laminating an aluminum foil as the metal foil 204c and a polyethylene terephthalate film as the base film 204a is used, the thickness of the aluminum foil can be 5 μm or more and 15 μm or less, and the thickness of the polyethylene terephthalate layer is It can be 6 μm or more and 25 μm or less. The thickness of the polyethylene terephthalate layer is preferably about 12 μm in terms of ease of processing with laser light, which will be described later.

いずれの場合も基材フィルム２０４ａには、ポリエチレンテレフタレート（ＰＥＴ）の他に、ナイロン、ポリプロピレン（ＰＰ）等の樹脂フィルムを用いることができる。特に、ＰＥＴの２軸延伸フィルムは、蒸着加工時や貼り合せ加工時に、伸縮が少ないので好適である。 In either case, a resin film such as nylon or polypropylene (PP) can be used as the base film 204a in addition to polyethylene terephthalate (PET). In particular, the PET biaxially stretched film is suitable because it has little expansion and contraction during the vapor deposition process and the laminating process.

接着層２０５には、ドライラミネート用接着剤やノンソルベントラミネート用接着剤を用いてもよいし、押出し加工によりポリオレフィン系樹脂により接着してもよい。塗布量は０．５ｇ／ｍ２以上７．０ｇ／ｍ２以下が好ましい。 An adhesive for dry laminating or an adhesive for non-solvent laminating may be used for the adhesive layer 205, or a polyolefin-based resin may be used for bonding by extrusion processing. The coating amount is preferably 0.5 g / m 2 or more and 7.0 g / m 2 or less.

シーラント層２０６には、ＨＤＰＥ、ＭＤＰＥ、ＬＤＰＥ、ＬＬＤＰＥ等が使用できる。また、一部ポリブテンを含む層があってもよい。上述の材質の中でも、特に、ＬＬＤＰＥが好適である。とりわけ密度０．９２５ｇ／ｃｍ３以下、ＭＩ（メルトインデックス）４以上のものが好ましい。シーラント層２６は、Ｔダイ法やインフレーション法で製膜された無延伸フィルムが好ましく用いられる。 HDPE, MDPE, LDPE, LLDPE and the like can be used for the sealant layer 206. In addition, there may be a layer containing a part of polybutene. Among the above-mentioned materials, LLDPE is particularly preferable. In particular, those having a density of 0.925 g / cm 3 or less and an MI (melt index) of 4 or more are preferable. As the sealant layer 26, a non-stretched film formed by a T-die method or an inflation method is preferably used.

脆弱部１０５は、少なくとも紙基材層２０２及び基材フィルム層２０４に所定深さで形成された溝状の傷加工部２０７ａ、２０７ｂにより構成される。傷加工部２０７ａは、少なくとも紙基材層２０２に形成されていればよく、図４に示すように、紙基材層２０２とともに、紙基材層２０２の外方に積層された熱可塑性樹脂層２０１及び印刷層２０８に形成されてもよい。傷加工部２０７ｂは基材フィルム層２０４を貫通しない深さで形成されることが望ましいが、狭い範囲で貫通したとしてもバリア性に影響は少ないため、部分的であれば、基材フィルム層２０４を貫通していてもよい。傷加工部２０７ａ、２０７ｂは、レーザー光や刃型等の周知の技術を用いて形成することができる。 The fragile portion 105 is composed of groove-shaped scratch processing portions 207a and 207b formed at least in the paper base material layer 202 and the base film layer 204 at a predetermined depth. The scratched portion 207a may be formed at least on the paper base material layer 202, and as shown in FIG. 4, the thermoplastic resin layer laminated on the outer side of the paper base material layer 202 together with the paper base material layer 202. It may be formed on the 201 and the print layer 208. It is desirable that the scratched portion 207b is formed at a depth that does not penetrate the base film layer 204, but even if it penetrates in a narrow range, the barrier property is not affected so much. Therefore, if it is partial, the base film layer 204 May be penetrated. The scratched portions 207a and 207b can be formed by using a well-known technique such as laser light or a blade mold.

シート材２００の積層構造は、この構造に限定されず必要な機能に応じて各層の厚み、積層順序、材質を任意に変更できる。 The laminated structure of the sheet material 200 is not limited to this structure, and the thickness, stacking order, and material of each layer can be arbitrarily changed according to the required functions.

図５Ａ及び図５Ｂに、包装容器１００を押し潰す工程を示す。図５Ａに示すように、本工程において、包装容器１の使用者は、対向する２つの側面板１１１ａを互いに接する方向に押し込むことで胴部１０２を押し潰す。このとき、側面板１１１ｂは、包装容器１００の内部方向に折り畳まれる。 <Crushing process>
5A and 5B show a step of crushing the packaging container 100. As shown in FIG. 5A, in this step, the user of the packaging container 1 crushes the body portion 102 by pushing the two facing side plates 111a in the direction in which they are in contact with each other. At this time, the side plate 111b is folded in the internal direction of the packaging container 100.

本工程で、使用者は、分断部１１６を使用することができる。具体的には、図５Ｂに示すように、親指１１９等により分断部１１６を包装容器１００の内方に向かって押し込むことにより、分断部１１６全体が徐々に変形し、折返し板１０８及び側面板１１１ｂを包装容器１００の内方に、小さな力で容易に折り畳むことができる。 In this step, the user can use the dividing portion 116. Specifically, as shown in FIG. 5B, by pushing the divided portion 116 inward of the packaging container 100 with a thumb 119 or the like, the entire divided portion 116 is gradually deformed, and the folded-back plate 108 and the side plate 111b Can be easily folded inside the packaging container 100 with a small force.

＜折曲げ工程＞
図５Ｃに、包装容器１００を脆弱部１０５に沿って折曲げる工程を示す。本工程において、使用者は、初めに、側面板１１１を脆弱部１０５に沿って一方向へ折曲げる（図５Ｃの左図）。その後、側面板１１１を脆弱部１０５に沿って、先ほどと反対の方向に折曲げる（図５Ｃの右図）。折曲げは、各方向に複数回行ってもよい。本工程により、脆弱部１０５の破断が進行する。 <Bending process>
FIG. 5C shows a step of bending the packaging container 100 along the fragile portion 105. In this step, the user first bends the side plate 111 in one direction along the fragile portion 105 (left view of FIG. 5C). After that, the side plate 111 is bent along the fragile portion 105 in the opposite direction to the previous one (right figure in FIG. 5C). The bending may be performed a plurality of times in each direction. By this step, the fragile portion 105 is broken.

＜屋根板分離工程＞
図５Ｄに、脆弱部１０５に沿って、頂部１０１及び側面板１１１の一部を包装容器１００から分離する工程を示す。本工程において、使用者は、側面板１１１の一部を、脆弱部１０５に沿って、包装容器１００から引裂いて分離する（図５Ｄの左図）。前工程において、脆弱部１０５には、少なくとも部分的に破断が生じているため、使用者は脆弱部１０５を起点としてわずかな力で側面板１１１の上部を分離することができる。分離された包装容器１００は、図５Ｄの右図に示すように、胴部１０２上部及び頂部１０１と、胴部１０２下部とが別々に分離された状態に分離される。 <Roof plate separation process>
FIG. 5D shows a step of separating a part of the top 101 and the side plate 111 from the packaging container 100 along the fragile portion 105. In this step, the user tears and separates a part of the side plate 111 from the packaging container 100 along the fragile portion 105 (left figure in FIG. 5D). Since the fragile portion 105 is at least partially broken in the previous step, the user can separate the upper portion of the side plate 111 with a slight force starting from the fragile portion 105. As shown in the right figure of FIG. 5D, the separated packaging container 100 is separated into a state in which the upper portion and the top portion 101 of the body portion 102 and the lower portion of the body portion 102 are separately separated.

（変形例）
折返し板１０８及び側面板１１１ｂに補助罫線を追加することにより、折り畳みをより容易にすることができる。図６〜図８に、補助罫線を設けたブランク１１１〜１１３の部分平面図を示す。 (Modification example)
Folding can be made easier by adding an auxiliary ruled line to the folded plate 108 and the side plate 111b. 6 to 8 show partial plan views of blanks 111 to 113 provided with auxiliary ruled lines.

図６には、分断部１１６を囲む１本の円弧状曲線と２本の直線とからなる補助罫線１２２を含むブランク１１１を示す。図７には、分断部１１６を囲む４本の直線からなる菱形状の補助罫線１２３を含むブランク１１２を示す。図８には、分断部１１６から折返し板１０８または側面板１１１ｂの外縁に向かって延伸する仮想線上の所定範囲に形成された４本の補助罫線１２４を含むブランク１１３を示す。 FIG. 6 shows a blank 111 including an auxiliary ruled line 122 composed of one arcuate curve surrounding the divided portion 116 and two straight lines. FIG. 7 shows a blank 112 including a diamond-shaped auxiliary ruled line 123 composed of four straight lines surrounding the divided portion 116. FIG. 8 shows a blank 113 including four auxiliary ruled lines 124 formed in a predetermined range on a virtual line extending from the dividing portion 116 toward the outer edge of the folded plate 108 or the side plate 111b.

補助罫線は、分断部１１６を囲むもの、または分断部１１６から折返し板１０８または側面板１１１ｂの外縁に向かって延伸する仮想線上の所定範囲に形成されたものであれば、形状や本数は上記の形態に限定されない。 If the auxiliary ruled line surrounds the dividing portion 116 or is formed within a predetermined range on a virtual line extending from the dividing portion 116 toward the outer edge of the folded plate 108 or the side plate 111b, the shape and number of the auxiliary ruled lines are as described above. It is not limited to the form.

各補助罫線を追加することにより、補助罫線から折返し板１０８及び側面板１１１ｂが折れ曲がることが可能になるため、折返し板１０８及び側面板１１１ｂの押し込みから折り畳みまでがスムーズに進行する。このため、折り畳み作業がより容易になる。 By adding each auxiliary ruled line, the folded-back plate 108 and the side plate 111b can be bent from the auxiliary ruled line, so that the folding of the folded-back plate 108 and the side plate 111b proceeds smoothly from pushing to folding. Therefore, the folding work becomes easier.

実施例１〜４及び比較例に係る包装容器を作成し、折り畳みの容易さについて官能評価を行った。２リットルの容量の包装容器を作製するためのブランクを用意して、次のような包装容器を製造した。 The packaging containers according to Examples 1 to 4 and Comparative Examples were prepared, and sensory evaluation was performed on the ease of folding.
