Abstract
Description
【0001】
【発明の属する技術分野】
本発明は、コーヒー紅茶等のミルクや砂糖等を添加して、攪拌する飲料用の使い捨てマドラーに関するものである。
【0002】
【従来の技術】
現在、一般的に使い捨てマドラーの素材としては、特許文献1や2で、合成樹脂製のマドラーの改良特許が有るように、合成樹脂を用いたものが多いが、昨今の環境問題やコストから考慮すると、焼却可能で安価に製造できる紙製のマドラーが要望されていた。
【0003】
しかし、コーヒー紅茶等を飲用する場合、熱湯で抽出したり、溶かしたりする為に、紙の場合は、熱湯により吸水し易くなり、かき混ぜる為に必要な剛性を失ったり、紙表面にコーヒー等により着色したりして、品位を損なう等の結果となる為、熱湯用に使用できる紙製のマドラーは皆無であった。
【0004】
特許文献1: 実公平04−025023
特許文献2: 特開平09−276111
【0005】
【本発明が解決しようとする課題】
本発明は、上記の点に鑑みてなされたもので、紙を素材とした熱湯用にも使用できるマドラー用紙を提供するものである。
【0006】
【課題を解決するための手段】
本発明者らは、前記の課題を解決すべく鋭意検討を行なった結果、天然パルプを主成分とするパルプ配合であり、ロジンサイズ剤を対パルプ固形0.25重量%以上添加し、オンマシンカレンダーで締めて、坪量700g/m2 以上で密度0.8g/cm3以上になるように抄紙する事により、吸水性を吸水度(JISP 8140 紙及び板紙−吸水度試験方法)で20g/m2以下に押え、マドラーを使用して撹拌する時間内(約10秒程度)で、吸水によるくたくた感も起きず、また紙表面への色の付き方も撹拌する前と殆ど変わらないことを見出した。
【0007】
また同じく上記処方の内、ロジンサイズ剤の代わりにまたは加えて90℃以上の高融点ワックスエマルジョンを内添薬品に用いても、ワックスの撥水効果により、また高融点の為、低融点ワックスの様に熱湯により溶け出す事もなく、ロジンサイズ剤を使用した時と同様に、コーヒーの吸水性を吸水度で20g/m2以下に押え、吸水によるくたくた感も起きず、紙表面への色の付き方も、撹拌する前と殆ど変わらないマドラー用紙を提供できる事を見出した。
【0008】
本発明で使用されるロジンサイズ剤とは、松ヤニを原料とした内添サイズ剤であり、例えばAL−120(星光PMC製)、コロパールESN(星光PMC製)がある。本発明で使用される高融点ワックスエマルジョンは90℃以上の融点を有するワックスであれば初期の効果を達成することができる。高融点ワックスエマルジョンとしては例えばフェニックスFT−100(双葉化学製、融点98℃)、ポリロンA(中京油脂製、融点102℃)等がある。
【0009】
ロジンサイズ剤または高融点ワックスエマルジョンの使用量は、上述の吸水度を達成される量であり、対パルプ当たり0.25重量%以上、特に好ましくは0.29重量%以上であり、上限は特にないが、製品の価格を考慮して10重量%以下、特に8重量%以下、更に好ましくは5重量%以下が好ましい。両者に相容性がある場合には併用することが可能であり、その場合には合計量が上記の下限以上の量であることが必要である。
【0010】
本発明で使用されるパルプの主成分である天然パルプは、例えば広葉樹晒パルプ(L−BKP)、針葉樹晒パルプ(N−BKP)、漂白あるいは未漂白のNKP(針葉樹クラフトパルプ)やLKP(広葉樹クラフトパルプ)等であり、二次的成分として高歩留りパルプ[GP(破砕パルプ)、TMP(サーモメカニカルパルプ)等、古紙パルプまたは化学漂白パルプ、例えばECFまたはTCF漂白を行ったものも混入することができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a disposable drinkable stirrer for beverages to which milk and sugar such as coffee tea are added and stirred.
[0002]
[Prior art]
At present, as a material for disposable muddlers, there are many using synthetic resins, as in Patent Documents 1 and 2, which are patents for improving synthetic resin muddlers, but these are considered in view of recent environmental issues and costs. Then, there has been a demand for a paper mudler that can be incinerated and can be manufactured at low cost.
[0003]
However, when drinking coffee or tea, it can be extracted or dissolved with hot water, and in the case of paper, it becomes easier to absorb water with hot water and loses the rigidity required to stir, There was no paper mudler that could be used for boiling water because it would result in coloration or loss of quality.
[0004]

Patent Document 2: JP-A-09-276111
[0005]
[Problems to be solved by the present invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a madler sheet which can be used for hot water made of paper.
[0006]
[Means for Solving the Problems]
The present inventors have conducted intensive studies in order to solve the above-mentioned problems. As a result, the pulp composition is composed of natural pulp as a main component. Water absorption is determined by water absorption (JISP 8140 paper and paperboard-water absorption test method) at 20 g / cm3 by making a paper with a basis weight of 700 g / m 2 or more and a density of 0.8 g / cm 3 or more. m 2 presser below, within a time stirring using muddler (about 10 seconds), does not occur even exhausted feeling due to water absorption, also that almost the same as before also agitated way per color to the paper surface I found it.
[0007]
Also in the above formulation, a high melting point wax emulsion having a melting point of 90 ° C. or higher can be used as an internal chemical instead of or in addition to the rosin sizing agent. As in the case of using a rosin sizing agent, the water absorption of the coffee is suppressed to 20 g / m 2 or less in the same manner as when a rosin sizing agent is used. It has also been found that mudler paper, which is almost the same as before stirring, can be provided.
[0008]
The rosin sizing agent used in the present invention is an internally added sizing agent using pine tar as a raw material, and examples thereof include AL-120 (manufactured by Starlight PMC) and Coropearl ESN (manufactured by Starlight PMC). The initial effect can be achieved if the high melting point wax emulsion used in the present invention is a wax having a melting point of 90 ° C. or higher. Examples of the high melting point wax emulsion include Phoenix FT-100 (manufactured by Futaba Chemical Co., melting point: 98 ° C.) and Polylon A (manufactured by Chukyo Yushi, melting point: 102 ° C.).
[0009]
The amount of the rosin sizing agent or high melting point wax emulsion used is such that the above-mentioned water absorption is achieved, and is preferably 0.25% by weight or more, more preferably 0.29% by weight or more, based on pulp. However, in consideration of the price of the product, it is preferably 10% by weight or less, particularly preferably 8% by weight or less, more preferably 5% by weight or less. If both are compatible, they can be used together, in which case the total amount must be at least the above lower limit.
[0010]
The natural pulp which is a main component of the pulp used in the present invention is, for example, bleached hardwood pulp (L-BKP), bleached softwood pulp (N-BKP), bleached or unbleached NKP (softwood kraft pulp) or LKP (hardwood) Kraft pulp), and high yield pulp [GP (crushed pulp), TMP (thermo-mechanical pulp), etc., such as waste paper pulp or chemically bleached pulp, for example, ECF or TCF bleached. Can be.
