Description
本発明は、レーザープリンターを使用して任意の文字や図形を印刷するのに適した封筒と、その封筒の作製に用いる封筒用紙に関する。 The present invention relates to an envelope suitable for printing an arbitrary character or figure using a laser printer, and an envelope paper used for producing the envelope.
封筒としての体裁を既に整えている紙製袋状物に、宛名を含む任意の文字及び／又は図形を、インクジェットプリンターやレーザープリンターなどによって印刷することは、従来から行われている。しかし、印刷を完了してプリンターから排出される封筒に、印刷前には存在しなかった紙シワが目視されることが珍しくない。この紙シワは、自然には殆ど消滅しないため、印刷後の封筒の見映えを著しく損なう。また、封筒印刷にレーザープリンターを用いる場合には、プリンターに供給する封筒のタイプによっては、転写抜けが起る欠点があった。 2. Description of the Related Art Conventionally, an arbitrary character and / or figure including an address is printed on a paper bag-like product that has already been designed as an envelope by an inkjet printer, a laser printer, or the like. However, it is not uncommon for paper wrinkles that were not present before printing to be visually observed on the envelope that has been printed and discharged from the printer. Since the paper wrinkles hardly disappear naturally, the appearance of the envelope after printing is remarkably impaired. Further, when a laser printer is used for envelope printing, there is a drawback that transfer loss occurs depending on the type of envelope supplied to the printer.
従来の封筒の典型例は、長方形を呈する表紙の２つの長辺から、短辺長のほぼ１/２に相当する幅の紙片をそれぞれの長辺に連設させ、その２枚の連設紙片を長辺に沿って折り返し、自由端同士を糊付けして封筒の裏紙とする一方、上記表紙の２つの短辺からは、比較的狭い幅のフラップ片をそれぞれの短辺に連設させ、その一方を短辺に沿って折り返して前記裏紙に糊付けした構造にある。このタイプの封筒は、裏紙の糊付け部分が、中央に位置するので、センター貼り封筒と呼ばれており、裏紙の糊付け部分がどちらか一方の長辺に偏ったものは、横貼り封筒と呼ばれている。 A typical example of a conventional envelope is a paper piece having a width corresponding to about 1/2 of the short side length from two long sides of a rectangular cover, and the two continuous paper pieces. Is folded along the long side, and the free ends are glued together to form the backing paper of the envelope, while from the two short sides of the cover, a relatively narrow width flap piece is connected to each short side, One of them is folded along the short side and glued to the backing paper. This type of envelope is called a center-bonded envelope because the glued part of the backing paper is located in the center, and the one with the glued part of the backing paper biased to one of the long sides is being called.
センター貼り封筒や横貼り封筒は、糊付け部分で用紙が重なっているため、当然のことながら、その部分の厚さが他の部分のそれより厚い。このため、このタイプの封筒をレーザープリンターに供給し、封筒の糊付け部分とそうでない部分に跨る個所に、転写画像を形成させた場合には、封筒の段差に原因して転写抜けが発生してしまうのである。 In the center-bonded envelope and the laterally-bonded envelope, since the sheets are overlapped at the glued portion, the thickness of the portion is naturally thicker than that of the other portions. For this reason, when this type of envelope is supplied to a laser printer and a transfer image is formed at a location straddling the glued portion of the envelope and the portion that is not, the transfer omission occurs due to the level difference of the envelope. It ends up.
レーザープリンターにて封筒に印刷を施す場合の転写抜けは、その原因が封筒の段差に在ることから、センター貼りや横貼りの封筒に代えて、以下に述べる薬袋貼り封筒を使用することで解消させることができる。すなわち、２枚の矩形の用紙を重ね、１辺を残して３辺を糊付けする三方貼り封筒、或いは長方形の用紙を二つ折りし、底辺に対向する１辺を残して他の２辺を糊付けして作製される二方貼り封筒のような薬袋貼り封筒には、実質的な段差が生じないからである。
薬袋貼り封筒を開示した先行文献としては、例えば、特開平７−１７９０３３号公報（特許文献１）、特開２０００−１６４３９号公報（特許文献２）及び特開２００１−２４００８０号公報（特許文献３）を挙げることができる。
When printing on envelopes with a laser printer, transfer failure is caused by the level difference of the envelope, so it can be eliminated by using the following envelopes instead of center or side envelopes. Can be made. In other words, two rectangular sheets are stacked, a three-sided envelope that glues three sides, leaving one side, or a rectangular sheet is folded in half, and the other two sides are glued, leaving one side facing the bottom. This is because there is no substantial step in a medicine bag pasting envelope such as a two-sided pasting envelope.
As prior literatures that disclose envelopes attached with a medicine bag, for example, Japanese Patent Laid-Open Nos. 7-179033 (Patent Document 1), Japanese Patent Laid-Open No. 2000-16439 (Patent Document 2), and Japanese Patent Laid-Open No. 2001-240080 (Patent Document 3) ).
レーザープリンターにて封筒に印刷を施す場合の第１の問題は、紙シワの発生である。転写抜けを度外視すれば、従来の封筒であっても、梱包を解かれて間もない場合、あるいは解梱包後の封筒の保管に十分な注意が払われている場合には、レーザープリンターで印刷を行っても紙シワは殆ど発生しない。しかし、梱包から解かれた封筒の保管に、適度に調湿された環境を用意できるのは極めて稀であり、一般的には、プリンターが設置される様々な環境下で保管するのが通例である。
ちなみに、梱包から解かれた封筒が、高湿環境下に長時間放置されると、吸湿によって自然に開口部を開き、膨らんだ状態になり、この状態の封筒をレーザープリンターに供給すると、紙シワが発生し易くなる。梱包を解かれた封筒が、放置されると膨らむ現象は、センター貼りや横貼りの封筒に比較して薬袋貼り封筒では起こり難い。しかし、紙シワ発生の根本的な原因は、封筒用紙自体の性状に起因しているため、センター貼りや横貼りを薬袋貼りに変更しても、紙シワの発生を防止することが難しい。
The first problem when printing on envelopes with a laser printer is the occurrence of paper wrinkles. If you miss the missing transfer, print with a laser printer if it is a conventional envelope, or if it has just been unpacked, or if sufficient care is taken to store the envelope after unpacking. Paper wrinkles are hardly generated even when performing. However, it is extremely rare to prepare a moderately conditioned environment for storing envelopes that have been unpacked. In general, it is usually stored in various environments where printers are installed. is there.
By the way, if the envelope unpacked is left in a high humidity environment for a long time, the opening will naturally open due to moisture absorption and it will swell. Is likely to occur. The phenomenon that an unpacked envelope swells when left unattended is less likely to occur in a medicine bag envelope than in a center or horizontal envelope. However, since the fundamental cause of the occurrence of paper wrinkles is due to the properties of the envelope paper itself, it is difficult to prevent the occurrence of paper wrinkles even if center sticking or horizontal sticking is changed to medicine bag sticking.
封筒をレーザープリンターで印刷する場合の紙シワ発生の防止手段として、前掲の特許文献１は、封筒の表紙の内表面と裏紙の内表面との摩擦係数を、封筒の外表面同士の摩擦係数よりも大きくすることを提案している。また、これとは逆に、特開平７−４１００１号公報（特許文献４）には、封筒の表紙の内表面に低摩擦材料を塗工し、封筒の裏紙との間の摩擦係数を小さくすることが提案されている。
そして、前掲の特許文献２には、長方形の紙材シートを二つ折りしたタイプの薬袋貼り封筒において、紙材シートの繊維方向を封筒の長手方向に選び、前記繊維方向に直交する方向の紙材シートの剛度を４５〜７０ｍｇの範囲に設定するか、或いは、紙材シートの繊維方向を封筒の幅方向に選び、紙材シートの繊維方向の剛度を７０〜９０ｍｇの範囲に設定することによって、レーザープリンターでの紙シワ発生を防止することが記載されている。なお、特許文献２で言う紙材シートの剛度は、ガーレ式測定方法によるとされている。
As a means for preventing the occurrence of paper wrinkling when printing envelopes with a laser printer, the above-mentioned Patent Document 1 describes the friction coefficient between the inner surface of the envelope cover and the inner surface of the backing paper, and the friction coefficient between the outer surfaces of the envelope. Propose to be bigger than. On the contrary, in JP-A-7-41001 (Patent Document 4), a low friction material is applied to the inner surface of the envelope cover, and the coefficient of friction between the envelope and the backing paper is reduced. It has been proposed to do.
And in the above-mentioned patent document 2, in a medicine bag pasting envelope of a type in which a rectangular paper material sheet is folded in half, the fiber direction of the paper material sheet is selected as the longitudinal direction of the envelope, and the paper material in the direction orthogonal to the fiber direction By setting the stiffness of the sheet in the range of 45-70 mg, or by selecting the fiber direction of the paper sheet in the width direction of the envelope and setting the stiffness of the paper direction of the paper material sheet in the range of 70-90 mg, It is described to prevent paper wrinkling in a laser printer. In addition, the rigidity of the paper material sheet said in patent document 2 is said to be based on the Gurley method.
本発明の目的は、封筒としての堅牢さを備え、高湿環境下に保管された状態でレーザープリンターに供給された場合でも、転写抜けや紙シワが発生しないレーザープリンター用封筒と、その封筒の作製に用いる用紙を提供することにある。 An object of the present invention is to provide an envelope for a laser printer that has robustness as an envelope and does not cause transfer omission or paper wrinkles even when supplied to a laser printer in a state of being stored in a high humidity environment. It is to provide a sheet used for production.
本発明に係るレーザープリンター用封筒用紙は、横方向のガーレー剛度が１．８０ｍＮ以上であり、横方向の水中伸度が２．３０％以下であることを特徴とする。そして、本発明に係るレーザープリンター用封筒は、ガーレー剛度及び水中伸度について特定された上記の封筒用紙を裁断して得た矩形用紙を対向させ、薬袋貼りしたことを特徴とする。
なお、本発明に関して言うガーレー剛度の値は、後述する実施例及び比較例を含めて、「Ｊ．ＴＡＰＰＩ紙パルプ試験方法」Ｎｏ．４０に記載された方法に準拠して測定した値であり、同じく水中伸度の値は、「Ｊ．ＴＡＰＰＩ紙パルプ試験方法」Ｎｏ．２７−７８に記載されたＢ法に準拠して測定した値である。
The envelope paper for a laser printer according to the present invention is characterized in that the lateral Gurley stiffness is 1.80 mN or more and the lateral underwater elongation is 2.30% or less. The envelope for a laser printer according to the present invention is characterized in that a rectangular paper obtained by cutting the above-described envelope paper specified for Gurley stiffness and underwater elongation is made to face and a medicine bag is pasted.
The value of Gurley stiffness referred to in the present invention includes “J. TAPPI paper pulp test method” No. 1 including examples and comparative examples described later. 40. The value of the elongation in water is also the value of “J. TAPPI Paper Pulp Test Method” No. 40. It is the value measured based on the B method described in 27-78.
本発明によれば、封筒としての堅牢さを備え、高湿環境下に保管された状態でレーザープリンターに供給された場合でも、転写抜けや紙シワが発生しないレーザープリンター用封筒を得ることができる。 According to the present invention, it is possible to obtain an envelope for a laser printer that has robustness as an envelope and does not cause transfer omission or paper wrinkle even when supplied to a laser printer in a state of being stored in a high humidity environment. .
本発明の封筒用紙を抄紙する際の原料パルプには、広葉樹及び／又は針葉樹を原料とする木材パルプ（機械パルプ、半化学パルプ、化学パルプ）及び古紙パルプ（離解パルプ、脱墨パルプ）などを任意に選択することができるが、本発明で規定する剛度（ガーレー剛度を言う。以下同じ）を満足する用紙を得るためには、原料パルプに使用するパルプ全量の８０質量％以上を広葉樹パルプとすることが好ましい。広葉樹パルプは剛直で短いため、これを原料パルプに使用することは、最終的に得られる用紙を低密度化し、用紙剛度を増大させる上で有効である。また、塩素を用いずに漂白した、いわゆるＥＣＦパルプやＴＣＦパルプも好ましく用いられる。
原料に使用するパルプの叩解度は、パルプ繊維の性質に大きな影響を及ぼすので、叩解度の制御は大切である。本発明で使用する原料パルプの叩解度は、なかでも広葉樹パルプの叩解度は、カナダ標準ろ水度で少なくとも３５０ｃｃ以上、好ましくは４００〜５５０ｃｃ、より好ましくは４５０〜５００ｃｃの範囲に調整される。
The raw material pulp for making the envelope paper of the present invention includes wood pulp (mechanical pulp, semi-chemical pulp, chemical pulp) and waste paper pulp (disaggregated pulp, deinked pulp) etc. made from hardwood and / or softwood. Although it can be arbitrarily selected, in order to obtain a paper satisfying the rigidity defined in the present invention (referred to as Gurley rigidity, hereinafter the same), 80% by mass or more of the total amount of pulp used for the raw pulp is hardwood pulp. It is preferable to do. Since hardwood pulp is rigid and short, using it as a raw material pulp is effective in reducing the density of the final paper and increasing the paper stiffness. Moreover, what is called ECF pulp and TCF pulp bleached without using chlorine is also preferably used.
Since the beating degree of the pulp used as a raw material has a great influence on the properties of the pulp fiber, it is important to control the beating degree. The beating degree of the raw material pulp used in the present invention is adjusted to a Canadian standard freeness of at least 350 cc, preferably 400 to 550 cc, more preferably 450 to 500 cc.
本発明に係る封筒用紙は、原料パルプスラリーに常法通り、紙力増強剤、歩留まり向上剤、サイズ剤などで例示される内添薬剤を添加混合して紙料を調製し、これをシングルワイヤー式又はツインワイヤー式の長網抄紙機に供給して抄造される。
抄紙に際しての内添薬品の使用量は、適宜の範囲内で選択することができるが、本発明では、乾燥紙力増強剤及び湿潤紙力増強剤の使用量を、それぞれ対パルプ０．０５質量％（固形分）以上とすることが好ましい。これら紙力増強剤の使用量がこれより少ないと、たとえ原料パルプの８０質量％以上を、広葉樹パルプで構成させても、本発明で規定する剛度を満たす用紙を得ることができず、従って、レーザープリンターでの紙シワ発生や通紙不良を伴わない封筒用紙を得ることが難しいからである。しかし、上記紙力増強剤のそれぞれの使用量が対パルプ０．５質量％（固形分）を越えると、本発明に係る封筒を古紙として回収してこれを水中で離解する場合、あるいは本発明に係る封筒の作製時に出る損紙を回収して水中で離解する場合に、離解が困難になる不都合がある。従って、原料パルプスラリーに配合する乾燥紙力増強剤及び湿潤紙力増強剤は、その添加量を対パルプ０．０５〜０．５質量％（固形分）の範囲で選択することが好ましい。
本発明では、紙料へのカオリン、タルク、炭酸カルシウム等の填料の添加を排除するものではないが、填料を使用する場合は、最終的に得られる封筒用紙の灰分含有量が１５質量％以下、好ましく１０質量％以下、より好ましくは８質量％以下となるように、填料の使用量を選ぶことが好ましい。用紙の灰分含有量が１５質量％を越えると、封筒用紙の横方向のガーレー剛度が低下し、レーザープリンター通紙時に紙シワが発生することがある。
The envelope paper according to the present invention is prepared by adding an internal additive exemplified by a paper strength enhancer, a yield improver, a sizing agent, and the like to a raw pulp slurry as usual. Paper is made by feeding it to a twin or long wire paper machine.
The amount of internal chemicals used for papermaking can be selected within an appropriate range. In the present invention, the amounts of dry paper strength enhancer and wet paper strength enhancer are set to 0.05 mass per pulp, respectively. % (Solid content) or more is preferable. If the amount of these paper strength enhancers is less than this, even if 80% by mass or more of the raw pulp is composed of hardwood pulp, it is not possible to obtain a paper satisfying the rigidity defined in the present invention. This is because it is difficult to obtain envelope paper that does not cause paper wrinkles or poor paper passing in a laser printer. However, when the amount of each of the above paper strength enhancers exceeds 0.5% by mass (solid content) with respect to pulp, the envelope according to the present invention is recovered as waste paper and dissociated in water, or the present invention. There is an inconvenience that it becomes difficult to disintegrate when collecting the waste paper that is produced when the envelope according to the above is collected and disaggregating in water. Therefore, it is preferable to select the addition amount of the dry paper strength enhancer and the wet paper strength enhancer blended in the raw pulp slurry in the range of 0.05 to 0.5% by mass (solid content) with respect to the pulp.
In the present invention, addition of fillers such as kaolin, talc and calcium carbonate to the paper is not excluded. However, when using a filler, the ash content of the envelope paper finally obtained is 15% by mass or less. The amount of filler used is preferably selected so that it is preferably 10% by mass or less, more preferably 8% by mass or less. When the ash content of the paper exceeds 15% by mass, the lateral Gurley stiffness of the envelope paper decreases, and paper wrinkles may occur when the laser printer is passed.
長網抄紙機で紙料を抄造した場合、パルプ繊維はワイヤーの流れる方向（縦方向）に並ぶ傾向が強い。紙の縦方向の性質は、横方向のそれに比較して引っ張り強度が大きく、伸びが小さく、引裂き強度が小さく、耐折強度が大きいなどの特徴があり、本発明で規定する剛度及び水中伸度について言えば、両者とも縦方向よりも横方向の方が剛度は小さく、水中伸度は大きいのが通例である。
本発明では、封筒用紙の横方向のガーレー剛度を、１．８０ｍＮ以上、好ましくは１．９０ｍＮ以上と規定し、横方向の水中伸度を２．３０％以下、好ましくは２．００％以下と規定することで、この用紙から得られる薬袋貼り封筒のレーザープリンターでの紙シワ発生を予防できる。
さらに、貼り合わせ方法については薬袋貼りとし、より好ましくは三方貼りが良い。二方貼りでは、吸湿した際に折返し部分で封筒用紙の膨らみが生じやすくなり、紙シワが発生する場合がある。
一方、上記のガーレー剛度が８．００ｍＮを超えると、レーザープリンター内の用紙搬送路の湾曲部分で、用紙の円滑な通過が損なわれることがある。また、封筒内へ内容物を収納しづらくなる問題もある。そして、上記の水中伸度が２．３０％を超えた場合には、紙シワが発生し易くなる。
When paper stock is made with a long paper machine, pulp fibers tend to line up in the direction in which the wire flows (longitudinal direction). Longitudinal properties of paper are characterized by high tensile strength, small elongation, low tear strength, and high bending strength compared to those in the horizontal direction. As for, both are generally less rigid in the transverse direction than in the longitudinal direction and greater in water elongation.
In the present invention, the lateral Gurley stiffness of the envelope paper is specified to be 1.80 mN or more, preferably 1.90 mN or more, and the lateral elongation in water is 2.30% or less, preferably 2.00% or less. By prescribing, it is possible to prevent the occurrence of paper wrinkles in the laser printer of the envelope with a medicine bag obtained from this paper.
Furthermore, as for the bonding method, a medicine bag is attached, more preferably a three-sided attachment. In the two-sided sticking, the envelope paper tends to swell at the folded portion when moisture is absorbed, and paper wrinkles may occur.
On the other hand, if the Gurley stiffness exceeds 8.00 mN, the smooth passage of the paper may be impaired at the curved portion of the paper conveyance path in the laser printer. There is also a problem that it becomes difficult to store the contents in the envelope.
