Abstract
[Problem] To provide a method for manufacturing a paper straw in which a drip phenomenon (staining) does not occur and discomfort at a drinking opening is not caused. [Solution] This method comprises: cutting, into an unfolded shape of a straw to be formed, flat paper having a narrow rectangular shape in a paperboard state and made of paper laminated with a thermoplastic resin having a heat seal function or of a plant-based material; folding both end parts which form a lateral surface part, with one end part folded on the inner side and the other end part on the outer side; and with an outer side fold portion arranged on the inner side and an inner side fold portion on the outer side, adhering the fold portions together in an overlap state such that the leading ends thereof are in a contact or a separated state. Thus, a drip phenomenon is prevented from occurring in both the inner surface and the outer surface.
Description
この発明は、紙製・植物性等の素材による飲料用ストローを製造する方法に係り、詳記すれば、貼り合わせ部分にドリップ(シミ)現象が生じるのを防止した紙製・植物性等の素材による飲料用ストローの製造方法に関する。
The present invention relates to a method for producing a beverage straw made of a material such as paper or vegetable, and more specifically, a paper or vegetable straw that prevents a drip (stain) phenomenon from occurring in the bonded portion. Regarding the manufacturing method of beverage straws by material.
環境保護に対する意識の高まりを受け、プラスチック製ストローを廃止する動きが海外で広がっている。紙製ストローも市販されているが、高価となる欠点があった。紙製・植物性等の素材でストローを作ると、貼り合わせ部分に、ドリップ(シミ)現象が生じる。そのため、紙の切断面を内面及び外面共に来ないようにする必要がある。紙の切断面を内面及び外面共に来ないように、二つ折りにした部分を重ね合わせると、貼り合わせ部分の厚みによる飲み口の不快さや製造上の難しさにつながる。そればかりか、特に外面の貼り合わせ部分への浸透によるドリップが生じ、それが目立ってしまう。
In response to growing awareness of environmental protection, the movement to abolish plastic straws is spreading overseas. Paper straws are also commercially available, but they have the drawback of being expensive. If you make a straw from a material such as paper or vegetable, a drip (stain) phenomenon will occur at the bonded part. Therefore, it is necessary to prevent the cut surface of the paper from coming to both the inner surface and the outer surface. If the folded parts are overlapped so that the cut surface of the paper does not come to both the inner surface and the outer surface, the thickness of the bonded portion leads to discomfort in the mouthpiece and manufacturing difficulty. Not only that, drip occurs due to penetration into the bonded part of the outer surface, which becomes conspicuous.
この発明は、このような欠点を解消しようとするものであり、内面外面共にドリップ(シミ)現象が生じず、しかも飲み口の不快さも生じないほか、安価に製造し得る紙製ストローを製造する方法を提供することを目的とする。
The present invention is intended to eliminate such drawbacks, and produces a paper straw that does not cause drip (stain) phenomenon on both the inner and outer surfaces, does not cause discomfort in the mouth, and can be manufactured at low cost. The purpose is to provide a method.
上記目的を達成するため、本発明者は、鋭意研究の結果、紙や植物性の素材(草、竹、その他)による板紙状態の細長い長方形の平板紙を、側面部となる両端部を一方を内側に他方を外側に折曲し、外側折曲部片を内側に、内側折曲片を外側にして、重合状態で折曲片同士は、先端が接触若しくは離間状態として、貼着させることにより、ストローの表裏面共に紙の切断部は出ないので、ドリップ現象が生じないストローの形成に成功した。折曲部同士が重合状態では、外面にドリップ現象が生じ得るし、紙が厚くなり、外見も悪く、貼りつき具合も完璧とは言えず、安定しない。本願発明は、折曲部同士は重合していないので3重であり、又は両折曲片の内側のみを削る事も出来、1/2づつ削つた場合は2重の厚さになるので、何ら問題は生じ無い。尚、折曲部とは、折曲片とそれに連設したストロー状部の一部を含む折り返し部の意味である。
前記外側折曲片と内側折曲片の裏面を、薄く削ることによって、折曲部を薄くすることができる(請求項2)。 In order to achieve the above object, the present inventor, as a result of diligent research, made a long and narrow rectangular flat paper in a paperboard state made of paper or a vegetable material (grass, bamboo, etc.) By folding the other inside to the outside, the outer bent part piece to the inside, and the inner bent piece to the outside, the folded pieces are attached to each other with the tips in contact with or separated from each other in the overlapped state. Since there is no cut part of the paper on both the front and back sides of the straw, we succeeded in forming a straw that does not cause the drip phenomenon. When the bent parts are overlapped with each other, a drip phenomenon may occur on the outer surface, the paper becomes thick, the appearance is bad, the sticking condition is not perfect, and the paper is not stable. In the present invention, since the bent portions are not overlapped with each other, the thickness is triple, or only the inside of both bent pieces can be scraped, and when scraped by 1/2, the thickness becomes double. No problem occurs. The bent portion means a folded portion including a bent piece and a part of a straw-shaped portion connected thereto.
The bent portion can be thinned by thinly scraping the back surfaces of the outer bent piece and the inner bent piece (claim 2).

When the bent parts are overlapped with each other, a drip phenomenon may occur on the outer surface, the paper becomes thick, the appearance is bad, the sticking condition is not perfect, and the paper is not stable.
