【産業上の利用分野】[Industrial applications]

本考案は、果汁飲料、清酒、牛乳などの食品やシャンプー、リンスなどの非食 品に用いられる液体用紙容器に関するものである。 The present invention relates to a liquid paper container used for foods such as fruit juice drinks, sake, and milk, and non-food products such as shampoos and conditioners.

【0002】[0002]

【従来の技術】[Prior art]

近年、頂部が切妻形又は平面状の液体用紙容器が、従来のガラス容器や金属容 器にかわって、牛乳、乳酸菌飲料、液体スープなどのチルド流通タイプや、清酒 、果汁飲料、めんつゆなどの長期保存を必要とする常温タイプの液体食品などの 広い範囲にわたって、大量に使用されるようになって来た。最近では、さらにト イレタリーなどの非食品にも使用されるようになった。これらの液体用紙容器に 使用されている基材は、積層材料であり、例えば、チルドタイプの液体食品に対 しては、比較的に簡単なポリエチレン層/紙層/ポリエチレン層構成の積層材料 が用いられ、常温流通タイプの液体食品には、ガスバリヤ性と光遮断性とを兼ね 備えた、ポリエチレン層/紙層/アルミニウム箔層/ポリエチレンテレフタレー ト層/ポリエチレン層構成などの積層材料が用いられていた。そして、これらの 積層材料の紙層には、バージンパルプ(virgin pulp)のみで抄紙さ れた原紙が使用されていた。 In recent years, gable-shaped or flat-shaped liquid paper containers have replaced the conventional glass containers and metal containers with chilled distribution types such as milk, lactic acid bacteria drinks, liquid soups, and long-term drinks such as sake, fruit juice drinks, and noodle soups. It has come to be used in large amounts in a wide range of applications such as liquid foods of room temperature type that require preservation. Recently, it has also been used for non-food items such as textiles. The base material used in these liquid paper containers is a laminated material. For chilled liquid foods, for example, a relatively simple laminated material of polyethylene layer / paper layer / polyethylene layer structure is used. For room temperature distribution type liquid foods, laminated materials such as polyethylene layer / paper layer / aluminum foil layer / polyethylene terephthalate layer / polyethylene layer structure, which have both gas barrier property and light shielding property, are used. Was there. In addition, for the paper layers of these laminated materials, base papers made with only virgin pulp were used.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、近年、消費者の環境意識の高まりに伴い、日常生活の見直しと 共に、消費行動にも変化が見られ、環境問題を配慮したパッケージが消費者から も求められるようになり、環境問題と資源の有効利用の観点から、故紙を再生し たパルプ(renewable pulp)を使用したパッケージの開発が社会 的に盛んになって来ている。本考案は、このような社会情勢に応えるために開発 された液体用紙容器で、実用時に問題を発生しないように配慮して、故紙を使用 したものである。 However, in recent years, along with the increasing environmental awareness of consumers, along with the review of daily life, there has been a change in consumption behavior, and consumers are now demanding packages that consider environmental issues. From the viewpoint of effective use of resources, the development of packages using recycled pulp from recycled paper has become socially popular. The present invention is a liquid paper container developed to respond to such a social situation, and uses waste paper in consideration of no problem during practical use.

【0004】[0004]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、基材に積層材料を用いた液体用紙容器において、図1及び図2に示 したように、基材(100)の紙層(110)に、少なくとも表面層(11)の 一層をバージンパルプのみで抄紙し、他の層を故紙から再生したパルプをバージ ンパルプに混合して抄紙した多層抄紙の原紙(10)を使用した液体用紙容器( 1)である。 The present invention relates to a liquid paper container using a laminated material as a base material, as shown in FIGS. 1 and 2, in which at least one surface layer (11) is provided on the paper layer (110) of the base material (100). A liquid paper container (1) using a base paper (10) for multi-layer papermaking, which is made by making paper only with virgin pulp and mixing other layers with pulp regenerated from waste paper with virgin pulp.

【0005】 上述の多層抄紙した原紙は、通常、表面層/中間層/裏面層の3層構成か、表 面層/表内側層/中間層/裏内側層/裏面層の5層構成のものである。The above-mentioned multi-layered base paper usually has a three-layer structure of surface layer / intermediate layer / back surface layer, or a five-layer structure of front surface layer / front inner layer / intermediate layer / back inner layer / back surface layer. Is.

【0006】 また、故紙を再生したパルプのバージンパルプへの混抄率は、5%から95% である。Further, the mixing ratio of recycled pulp from recycled paper to virgin pulp is 5% to 95%.

【0007】[0007]

【作用】[Action]

故紙を再生したパルプをバージンパルプに混合すると、抄紙した原紙の物性や 外観性を損なう場合がある。このため、故紙を再生したパルプをバージンパルプ を混抄した原紙を基材の紙層に使用すると、液体用紙容器の容器物性や商品価値 を著しく落とす恐れがある。しかし、本考案の液体用紙容器に使用する原紙は、 多層抄紙されたものであり、少なくとも表面層がバージンパルプのみで抄紙され ているため、故紙を再生したパルプを混抄した原紙を基材の紙層に用いても、容 器の流通時や使用時に問題となるような物性劣化や、容器の外観から商品の商品 価値を落とようなことはない。 When virgin pulp is mixed with recycled pulp from recycled paper, it may impair the physical properties and appearance of the raw paper produced. For this reason, when the raw paper obtained by mixing recycled pulp with virgin pulp is used for the paper layer of the base material, the physical properties and commercial value of the liquid paper container may be significantly reduced. However, the base paper used for the liquid paper container of the present invention is a multi-layered paper, and since at least the surface layer is made of virgin pulp only, the base paper made from a mixture of recycled pulp of waste paper is used as the base paper. Even when used as a layer, it does not deteriorate the physical properties that may cause problems during distribution or use of the container, or reduce the product value of the product due to the appearance of the container.

【実施例】【Example】

<実施例1> まず、本実施例の基材の紙層に使用する多層抄紙の原紙を3種類作製した。こ れらの原紙は、図1に示したように、表面層(11)/表内側層(12)/中間 層(13)/裏内側層(14)/裏面層の5層に抄紙しされたものである。そし て、表面層と裏面層の2層は、バージンパルプのみで抄紙し、他の表内側層、中 間層、裏内側層の3層は、例えば、新聞脱墨故紙などの故紙から再生したパルプ をバージンパルプに混合して抄紙したもので、原紙の全体に対する故紙から再生 したパルプのバージンパルプへの混抄率は、8%、15%、25%の3種類のも のである。これらの原紙の特性を表1に従来の原紙と合わせて記載した。この表 からは、剛度及び白色度が故紙の混抄率が増すと減少する傾向にあった。 Example 1 First, three types of multi-layer paper base papers used for the paper layers of the base material of this example were prepared. As shown in FIG. 1, these base papers are made into five layers of surface layer (11) / front inner layer (12) / intermediate layer (13) / back inner layer (14) / back surface layer. It is a thing. Then, the two layers of the front layer and the back layer were made with only virgin pulp, and the other three layers of the front and inner layers, the middle layer and the back inner layer were regenerated from waste paper such as newspaper deinked waste paper. Pulp was mixed with virgin pulp to make paper, and the mixing ratio of recycled pulp from waste paper to virgin pulp was 8%, 15%, and 25% of the total amount of base paper. The characteristics of these base papers are shown in Table 1 together with the conventional base papers. From this table, the stiffness and whiteness tended to decrease as the mixing ratio of waste paper increased.

【0009】[0009]

【表1】 [Table 1]

【0010】 次に、作製した3種類の故紙から再生したパルプを混抄した原紙を用いて、本 実施例の液体用紙容器の基材(100)を作製した。基材の積層構成は、図2に 示したように、〔容器外側〕20μm 厚ポリエチレン層(120)/320g/m2 紙層(110)/25μm アイオノマー層(130)/7μm 厚アルミニウム箔 層(140)/12μm ポリエチレンテレフタレート層(150)/60μm ポ リエチレン層(160)〔容器内側〕の6層であり、作製した3種類の原紙を紙 層に用いて、ラミネート加工法によってそれぞれの3種類の液体用紙容器の基材 を作製した。また、比較のために、バージンパルプのみで抄紙した原紙を紙層に 用いた従来の液体用紙容器の基材も合わせて作製した。Next, a base paper (100) for a liquid paper container of this example was manufactured using a base paper obtained by mixing pulp prepared by recycling the three kinds of waste paper. As shown in Fig. 2, the laminated structure of the base material was as follows: [outside the container] 20 μm thick polyethylene layer (120) / 320 g / m 2 paper layer (110) / 25 μm ionomer layer (130) / 7 μm thick aluminum foil layer ( 140) / 12μm polyethylene terephthalate layer (150) / 60μm polyethylene layer (160) [inside the container], 6 layers, using 3 types of the prepared base paper for the paper layer and 3 types of each by the laminating method. A base material for a liquid paper container was prepared. For comparison, a base paper of a conventional liquid paper container using a base paper made of only virgin pulp as a paper layer was also prepared.

【0011】 次に、前述の4種類の液体用紙容器の基材を用いて、ブランク板を作製し、折 り畳み、熱風シールし、水を充填して容器を密封し、図4に示した頂部が平面の 600mlの3種類の本実施例の液体用紙容器(1)と1種類の従来の液体用紙 容器とを作製した。なお、この製箱工程において、ブランク板の罫線加工や折り 曲げ加工などの加工適性については、故紙から再生したパルプの混抄による影響 が全く認められなかった。また、容器の外観性も従来の容器と変わらず、故紙か ら再生したパルプの混抄による商品価値の損失はなかった。Next, using the above-mentioned four types of liquid paper container base materials, blank plates were prepared, folded, hot-air sealed, and filled with water to seal the container, as shown in FIG. Three types of liquid paper containers (1) of the present example having a flat top portion of 600 ml and one type of conventional liquid paper container were prepared. In this box-making process, no influence was observed on the processing suitability of the blank plate such as ruled line processing and bending processing due to the mixing of pulp recycled from waste paper. In addition, the appearance of the container was the same as that of conventional containers, and there was no loss of product value due to the mixed papermaking of recycled pulp from waste paper.

【0012】 次に、故紙から再生したパルプの混抄率の容器の強度に対する影響を調べるた めに、4種類の液体用紙容器を、所定の高さからコンクリート床上に常温で繰り 返し正垂落下させて、容器が破壊する発生回数を求めた。この結果を表2に示し たが、80cmの高さでは、どの容器も10回の落下では破壊されなかったが、 120cmの高さでは、従来の容器が5回目の落下で破壊したのに対して、故紙 から再生したパルプの混抄した3種類の容器は、いずれも4回目の落下で破壊し た。この結果、故紙から再生したパルプの混抄した原紙を用いると、落下衝撃強 度が減少する傾向が窺えた。しかし、この落下衝撃強度の差は、過去の経験から 実用上では従来の容器と同等であり、支障のないことが分かっている。Next, in order to investigate the influence of the mixing ratio of pulp recycled from waste paper on the strength of the container, four kinds of liquid paper containers were repeatedly dropped from a predetermined height on the concrete floor at room temperature and at normal temperature. Then, the number of times the container was destroyed was calculated. The results are shown in Table 2, and at a height of 80 cm, none of the containers were destroyed by 10 drops, whereas at a height of 120 cm, the conventional containers were destroyed by the fifth drop. As a result, all three types of mixed pulp containers recycled from waste paper were destroyed by the fourth drop. As a result, it was found that the drop impact strength tended to decrease when using a base paper containing a mixture of pulp regenerated from waste paper. However, it is known from past experience that this difference in drop impact strength is practically equivalent to that of conventional containers, and that there is no problem.

【0013】[0013]

【表2】 [Table 2]

【0014】 <実施例2> 実施例1で作製した原紙の全体に対する故紙から再生したパルプのバージンパ ルプへの混抄率が25%の5層の多層抄紙の原紙用いて、ラミネート加工法によ って、本実施例の液体用紙容器の基材(200)を作製した。基材の積層構成は 、図3に示したように、〔容器外側〕20μm 厚ポリエチレン層(220)/3 20g/m2紙層(210)/55μm ポリエチレン層(230)/12μm ポリエ チレンテレフタレート層(240)/60μm ポリエチレン層(250)〔容器 内側〕の5層である。<Example 2> [0014] Using a base paper of 5 layers of multi-layer paper having a mixing ratio of recycled pulp from waste paper to virgin pulp of 25% with respect to the whole of the base paper prepared in Example 1, a lamination method was used. Thus, the base material (200) of the liquid paper container of this example was produced. As shown in FIG. 3, the laminated structure of the base material is as follows: [Outside the container] 20 μm thick polyethylene layer (220) / 3 20 g / m 2 Paper layer (210) / 55 μm Polyethylene layer (230) / 12 μm Polyethylene terephthalate layer Five layers of (240) / 60 μm polyethylene layer (250) [inside the container].

【0015】 次に、作製した液体用紙容器の基材を用いて、ブランク板を作製し、折り畳み 、熱風シールし、水を充填して容器を密封し、図4に示した頂部が平面の600 mlの本実施例の液体用紙容器(1)を作製した。なお、この製箱工程において は、実施例1と同様に、ブランク板の罫線加工や折り曲げ加工などの加工適性に ついては、故紙から再生したパルプの混抄による影響が全く認められなかった。 また、容器の外観性も従来の容器と変わらず、故紙から再生したパルプの混抄に よる商品価値の損失はなかった。さらに、落下衝撃強度においても、実用上での 強度は従来の容器と同等であり、支障のないことが分かった。Next, a blank plate was prepared using the base material of the prepared liquid paper container, folded, hot air sealed, and filled with water to seal the container, and the top 600 shown in FIG. 4 was flat. A liquid paper container (1) of the present example of ml was prepared. In this box-making process, as in Example 1, no influence was observed on the processing suitability of the blank plate, such as ruled line processing and bending processing, by the mixed papermaking of pulp recycled from waste paper. In addition, the appearance of the container was the same as that of conventional containers, and there was no loss of commercial value due to the mixing of pulp recycled from waste paper. Furthermore, it was found that the drop impact strength was practically equivalent to that of conventional containers, and there was no problem.

【0016】[0016]

【考案の効果】[Effect of device]

本考案の液体用容器を使用すると、故紙を再生したパルプを使えるため、近年 の環境問題に応えることができ、ブランク板作製上の加工適性も良く、容器の落 下衝撃強度も実用上では、従来の液体用紙容器と同等である。 When the liquid container of the present invention is used, pulp made from recycled waste paper can be used, so that it can meet recent environmental problems, has good processability in making blank plates, and has a drop impact strength that is practically not applicable. It is equivalent to a conventional liquid paper container.
