Description
【０００１】
【発明の属する技術分野】
本発明はヨーグルト充填用の紙カップにヨーグルを充填したヨーグルト包装体に関し、特には、カップに充填した後に醗酵させてカップ内でヨーグルトにする後醗酵タイプのヨーグルトを用いたヨーグルト包装体に関する。
【０００２】
【従来の技術】
ヨーグルトには、醗酵前のヨーグルト原液をカップなどの容器に充填後に醗酵させて容器内でヨーグルトにする後醗酵タイプと、醗酵済みのヨーグルトをカップなどの容器に充填する前醗酵タイプとがある。果肉やアロエなどが混合しているヨーグルトは、ほとんどが前醗酵タイプである。
【０００３】
特に後醗酵タイプのヨーグルトにおいては、カップなどの容器に醗酵前のヨーグルト原液を充填し、蓋材を被せてシールした後の醗酵冷却環境でヨーグルト表面に泡や亀裂が発生することがある。
【０００４】
通常は、ヨーグルト（３０）をカップ容器に充填した際、ヨーグルトと胴部の接合部で発生した気泡（３１）は、接合部の隙間を上昇してヨーグルト表面に出て気泡は消えてしまう。ところがヨーグルトと胴部の接合部で発生した気泡が、ヨーグルトと接合部の隙間を上がってこられずに、固まったヨーグルト表面に亀裂（３２）を発生させながら上昇してくる場合がある。胴部材と底部材の接合部分にも気泡が発生するが、上昇はしない（図２参照）。
【０００５】
この現象は、紙カップにヨーグルトを充填し、開口部を蓋材でシールした後の、冷却工程でのヘッドスペースの減圧に起因するが、これは充填されたヨーグルトと、ヨーグルトが接触している紙カップ内面のポリエチレン樹脂膜との密着力に関係していることがわかった。
【０００６】
カップ原紙の両面又は片面に、溶融押し出しラミネート法により低密度ポリエチレン樹脂を１０〜５０μｍ程度塗布したポリエチレン加工紙を用いて紙カップを成形することが一般的であるが、この場合、ポリエチレン樹脂層の表面が粗れていると、ヨーグルト（固形分）はポリエチレン表面の凸部分に接触し、凹部分には乳清（液体分）が入り込む。これによりヨーグルトと容器胴部の壁面のポリエチレン樹脂層表面との接着力が弱くなり、発生した気泡は簡単に下から上へと上昇して抜けることができる。
【０００７】
ヨーグルトとポリエチレン樹脂層表面との密着力を落とす方法として、紙カップの成形工程でシリコーンオイルをポリエチレン樹脂面に塗布する方法が知られているが、この方法では、ヨーグルトを充填後、容器の開口部を密封する蓋材との密着力を低下させるという可能性がある。
【０００８】
【発明が解決しようとする課題】
本発明は、ヨーグルト用紙カップに関する以上のような問題点を解決するためになされたもので、特に後醗酵タイプのヨーグルトについて、ヨーグルト表面に気泡や亀裂の発生のないヨーグルト用紙カップを用いたヨーグルト包装体を提供することを課題とする。
【０００９】
【課題を解決するための手段】
本発明の請求項１の発明は、略扇形状の胴部材の一方の端縁ともう一方の端縁とを重ね合わせて接合部を形成させた、下方に向けて先細る円筒形状筒体からなる胴部と、略円形状で、かつ、周縁が下向きに起立した底部材からなる底部と、から構成され、また、胴部を構成する胴部材、底部を構成する底部材ともに、カップ原紙の片面又は両面に溶融押し出し法により低密度ポリエチレン樹脂を塗布したポリエチレン加工紙から形成され、開口部周縁が外側に巻き込まれたフランジを有する紙カップにヨーグルトが充填されたヨーグルト包装体であって、ヨーグルトが、醗酵前のヨーグルト原液を容器に充填後に醗酵させて容器内でヨーグルトにする後醗酵タイプであり、充填時にヨーグルトが接触する前記紙カップの低密度ポリエチレン樹脂層の表面粗さが平均粗さ（Ｒａ）で１．５〜２．０であることを特徴とする、ヨーグルト包装体である。
【００１０】
なお、ここで、表面粗さの平均粗さ（Ｒａ）は、ＪＩＳ Ｂ０６０１に定義されている表面粗さである。
【００１１】
このように請求項１記載の発明によれば、充填時にヨーグルトが接触する低密度ポリエチレン樹脂層の表面粗さをＲａで１．５〜２．０に規定しているので、ヨーグルトと低密度ポリエチレン樹脂層表面との接着力が弱くなり、気泡が発生しても発生した気泡は簡単に下から上へと上昇して抜けることができる。
【００１２】
【発明の実施の形態】
本発明のヨーグルト包装体を、一実施形態に基づいて以下に詳細に説明する。
本発明のヨーグルト包装体に用いるヨーグルト用紙カップ（１）は、例えば、図１に示すように、略扇形状の胴部材（１１）の一方の端縁ともう一方の端縁とを重ね合わせて接合部（１２）を形成させた、下方に向けて先細る円筒形状筒体からなる胴部（１０）と、略円形状で、かつ、周縁（２１）が下向きに起立した底部材（２２）からなる底部（２０）と、から構成され、開口部周縁が外側に巻き込まれたフランジ（１３）を有するものである。
【００１３】
また、胴部を構成する胴部材、底部を構成する底部材ともに、カップ原紙（１０１）の片面又は両面に溶融押し出し法により低密度ポリエチレン樹脂（１０２）を塗布したポリエチレン加工紙（１００）から形成され、低密度ポリエチレン樹脂層（１０２）の表面粗さがＲａで１．５〜２．０に設定されているものである。
【００１４】
紙カップは、一般的に公知の紙カップ成形機で容易に作製することができ、フランジ（１３）は、図示してないが、水平方向に加熱しながら加圧して偏平に押しつぶしても良い。
【００１５】
偏平に押しつぶすことにより、ヨーグルトを充填後、紙カップの開口部に蓋材を被せ、高周波シール法などの方法により紙カップのフランジと蓋材とを密封シールする際の密封シール性が向上する。
【００１６】
胴部を構成する胴部材や底部を構成する底部材に使用されるポリエチレン加工紙（１００）は、カップ原紙（１０１）の片面又は両面に溶融押し出し法により低密度ポリエチレン樹脂（１０２）を塗布したもので、溶融低密度ポリエチレン樹脂を冷却させながらカップ原紙に塗布する際に使用する金属製のクーリングロール表面の粗さを調整しておくことにより、仕上がる低密度ポリエチレン樹脂層の表面粗さをＲａで１．５〜２．０にすることができる。
【００１７】
低密度ポリエチレン樹脂層の表面粗さのＲａが１．５未満になると、紙カップにヨーグルト原液を充填し、蓋材を密封シールした後の醗酵冷却工程で、紙カップの接合部分で発生した気泡が、ヨーグルトと紙カップ（低密度ポリエチレン表面層）の隙間を上がってこられず、固まったヨーグルトに亀裂をつくりながら上昇してくるので、ヨーグルト表面に亀裂や気泡が入ってしまう。
【００１８】
また、低密度ポリエチレン樹脂層の表面粗さのＲａが２．１以上になると、ヨーグルト表面に亀裂や気泡が入ることはないが、蓋材と紙カップのフランジとを高周波シールした際の接着性が落ちるという問題が発生する。
【００１９】
【実施例】
以下実施例により本発明を詳細に説明する。
〈実施例１〉
先ず、Ｒａが１．５の粗さになるようなクーリングロールを用いて、溶融押し出しラミネート法により、坪量が３００ｇ／ｍ2 のヨーグルト用のカップ原紙（１０１）の片面に、低密度ポリエチレン樹脂層（１０２）を３０μｍの厚さに塗布したポリエチレン加工紙（１００）を作製した。
【００２０】
このポリエチレン加工紙（１００）から所定寸法の胴部材用ブランクと底部材用ロールを作製し、一般的に公知の紙カップ成形機を使用して、低密度ポリエチレン樹脂層（１０２）を内面にして、口径；６４ｍｍ、高さ；５５ｍｍ、底径；５３ｍｍ、テーパー角度；６°、フランジ幅；３．５ｍｍ、容量；１３２ｍｌの実施例１のヨーグルト用紙カップ（１）を作製した（図１参照）。

【００２５】
〈比較例３〉
比較例１の紙カップの低密度ポリエチレン樹脂層面に表面塗布剤であるシリコンオイルをスプレーにより適量塗布し、この紙カップに実施例１と同様に９０ｍｌの後醗酵タイプのヨーグルト原液を充填し、アルミニウム箔を主材料とする蓋材で高周波シール法により密封シールし、冷却醗酵させ、比較例３のヨーグルト入り紙カップであるヨーグルト包装体を作製した。
【００２６】
このようにして作製した実施例２種類、比較例３種類、合計５種類のヨーグルト入り紙カップであるヨーグルト包装体の充填したヨーグルト表面の気泡、亀裂の発生状態と紙カップフランジと蓋材との密封シール性を下記の方法により測定、観察した。その結果を表１に示す。

BACKGROUND OF THE INVENTION
The present invention relates to a yogurt packaged body in which a paper cup for yogurt filling is filled with yogurt , and in particular, to a yogurt package using a post-fermentation type yogurt that is fermented after being filled into a cup to make yogurt in the cup.
[0002]
[Prior art]
Yogurt includes a post-fermentation type in which a yogurt stock solution before fermentation is filled in a container such as a cup and then fermented to make yogurt in the container, and a pre-fermentation type in which a fermented yogurt is filled in a container such as a cup. Most yogurts mixed with pulp and aloe are pre-fermented.
[0003]
In particular, in a post-fermentation type yogurt, bubbles or cracks may be generated on the yogurt surface in a fermentation cooling environment after filling a container such as a cup with a pre-fermentation yogurt stock solution and covering with a lid.
[0004]
Normally, when the yogurt (30) is filled in the cup container, the bubbles (31) generated at the joint between the yogurt and the trunk rises to the surface of the yogurt through the gap between the joints, and the bubbles disappear. However, the bubbles generated at the joint between the yogurt and the body may not rise through the gap between the yogurt and the joint, and may rise while generating cracks (32) on the hardened yogurt surface. Bubbles are also generated at the joint between the body member and the bottom member, but the bubbles do not rise (see FIG. 2).
[0005]
This phenomenon is caused by the pressure reduction of the headspace in the cooling process after filling the paper cup with yogurt and sealing the opening with a lid. This is due to the paper cup in contact with the filled yogurt and the yogurt. It was found that this was related to the adhesion of the inner surface with the polyethylene resin film.
[0006]
It is common to form a paper cup using polyethylene-processed paper in which low-density polyethylene resin is applied to both sides or one side of the cup base paper by melt extrusion laminating about 10-50 μm. In this case, the surface of the polyethylene resin layer Is rough, the yogurt (solid content) comes into contact with the convex portion of the polyethylene surface, and whey (liquid content) enters the concave portion. This weakens the adhesive force between the yogurt and the polyethylene resin layer surface of the wall surface of the container body, and the generated bubbles can easily rise from the bottom to the top and escape.
[0007]
As a method for reducing the adhesion between the yogurt and the polyethylene resin layer surface, a method of applying silicone oil to the polyethylene resin surface in the paper cup molding process is known. In this method, after filling yogurt, the opening of the container There is a possibility that the adhesive force with the lid member that seals will be reduced.
[0008]
[Problems to be solved by the invention]
The present invention was made to solve the above-mentioned problems associated with yogurt paper cups, and in particular for post-fermentation type yogurts, yogurt packaging using yogurt paper cups that do not generate bubbles or cracks on the yogurt surface. The challenge is to provide a body .
[0009]
[Means for Solving the Problems]
The invention of claim 1 of the present invention is based on a cylindrical tubular body tapering downward, in which a joint portion is formed by overlapping one end edge and the other end edge of a substantially fan-shaped body member. And a bottom part composed of a bottom member having a substantially circular shape and a peripheral edge standing downward, and the body member constituting the body part and the bottom member constituting the bottom part are made of cup base paper. by one or both surfaces melt extrusion is formed from a polyethylene coated paper coated with low density polyethylene resin, the opening peripheral edge is a yogurt packaging body yoghurt is filled in a paper cup having a flange caught outward, yoghurt , yogurt stock solution before fermentation by the fermentation after filling the container is a fermentation type after which the yoghurt in the containers, low-density polyethylene trees of the paper cup yogurt is contacted at the time of filling Wherein the surface roughness of the layer is 1.5 to 2.0 in average roughness (Ra), a yoghurt package.
[0010]
Here, the average roughness (Ra) of the surface roughness is the surface roughness defined in JIS B0601.
[0011]
As described above, according to the first aspect of the present invention, the surface roughness of the low density polyethylene resin layer that the yogurt contacts at the time of filling is regulated to 1.5 to 2.0 by Ra. Even if the adhesive force with the resin layer surface becomes weak and bubbles are generated, the generated bubbles can easily rise from the bottom to the top and escape.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The yogurt package of the present invention is described in detail below based on one embodiment.
The yogurt paper cup (1) used in the yogurt packaging body of the present invention has, for example, as shown in FIG. 1, one end of the substantially fan-shaped body member (11) and the other end overlap each other. A body part (10) formed of a cylindrical cylindrical body tapering downward and having a joint part (12) formed thereon, and a bottom member (22) having a substantially circular shape and a peripheral edge (21) rising downward The bottom part (20) which consists of, and has the flange (13) by which the opening part periphery was wound in the outer side.
[0013]
Further, the body member constituting the body part and the bottom member constituting the bottom part are both formed from a polyethylene processed paper (100) obtained by applying a low density polyethylene resin (102) to one or both sides of the cup base paper (101) by a melt extrusion method. The surface roughness of the low density polyethylene resin layer (102) is set to 1.5 to 2.0 in terms of Ra.
[0014]
The paper cup can be easily produced by a generally known paper cup molding machine, and the flange (13) is not shown, but may be flattened by applying pressure while heating in the horizontal direction.
[0015]
By crushing flatly, after filling yogurt, the opening of the paper cup is covered with a lid, and the sealing and sealing performance when the flange of the paper cup and the lid are hermetically sealed by a method such as a high frequency sealing method is improved.
[0016]
The polyethylene processed paper (100) used for the body member constituting the body portion and the bottom member constituting the bottom portion is obtained by applying a low density polyethylene resin (102) to one or both sides of the cup base paper (101) by a melt extrusion method. By adjusting the roughness of the surface of the metal cooling roll used when the molten low density polyethylene resin is cooled and applied to the base paper of the cup, the surface roughness of the finished low density polyethylene resin layer is adjusted to Ra. 1.5 to 2.0.
[0017]
When Ra of the surface roughness of the low-density polyethylene resin layer is less than 1.5, bubbles generated at the joint portion of the paper cup in the fermentation cooling step after filling the paper cup with yoghurt stock solution and hermetically sealing the lid, The gap between the yogurt and the paper cup (low-density polyethylene surface layer) cannot be raised, and the yogurt is raised while making a crack in the hardened yogurt, so cracks and bubbles enter the yogurt surface.
[0018]
Also, when the surface roughness Ra of the low density polyethylene resin layer is 2.1 or more, cracks and bubbles do not enter the yogurt surface, but the adhesiveness when the lid material and the flange of the paper cup are sealed at high frequency is improved. The problem of falling occurs.
[0019]
