本発明は、カップ状紙製品並びにカップ状紙製品の製造
方法及びその装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cup-shaped paper product, a method for manufacturing the cup-shaped paper product, and an apparatus therefor.
従来、例えばホテル等に置かれているガラス製のカップ
には、埃が入らないように薄い紙で密封しであるが、こ
のカップの開口部に被せる適当なカップ状の蓋等のカッ
プ状紙製品があれば、このカップから取り外した蓋をピ
ーナツ、キャンデイ等の小菓子の入れ物としても利用で
き、便利であるとされている。Conventionally, for example, glass cups placed in hotels etc. are sealed with thin paper to prevent dust from entering. If the product is available, the lid removed from the cup can also be used as a container for small snacks such as peanuts and candy, which is said to be convenient.
かかる蓋として、第１５図に示すような使い捨ての薄い
アルミニウム類の短円筒状のＭｌｏｌを利用することが
考えられる。As such a lid, it is conceivable to use a short cylindrical Mlol made of disposable thin aluminum as shown in FIG. 15.
ところが、かかるアルミニウム類の蓋１０１を利用する
時には、第１６図に示すように、この蓋１０１をガラス
のカップ１０２に被せた状態では、蓋１０１とカップ１
０２との間の摩擦係数が小さいため、カップ１０２を持
ち運ぶ際、傾けることもあり、Ｍｌｏｌが滑り落ちるこ
とになり、好ましくない。However, when using such an aluminum lid 101, as shown in FIG. 16, when the lid 101 is placed over the glass cup 102, the lid 101 and the cup 1
Since the coefficient of friction between the cup 102 and the cup 102 is small, when carrying the cup 102, the cup 102 may be tilted, which may cause the Mlol to slip off, which is undesirable.
そこで、アルミニウム類のＭｌｏｌに代えて紙製の蓋を
使用すれば滑り落ち難くなると考えられるが、使い捨て
ができる簡単な構造の一体型の紙製の蓋が望ましい。か
かる一体型の紙製の有底円筒状の蓋を成形しようとして
も、次の問題点がある。Therefore, it is thought that if a paper lid is used instead of Mlol, which is made of aluminum, it will be difficult to slip off, but a single-piece paper lid that is disposable and has a simple structure is desirable. Even if an attempt is made to form such an integrated paper lid in the form of a bottomed cylinder, the following problems arise.
立体形状の有底円筒状の紙製の蓋を成形するに際しては
、平面である円形状紙材を材料とすることが適当である
が、この場合、紙材は金属と違って伸縮性がほとんど無
いので、蓋の周壁面にプリーツを造って一部重なる部分
を形成すれば良いが、周壁面にプリーツがあると、プリ
ーツが拡がってしまい形状を維持することができない。When molding a three-dimensional bottomed cylindrical paper lid, it is appropriate to use flat circular paper as the material, but unlike metal, paper has little elasticity. Since this is not the case, pleats can be made on the peripheral wall of the lid to form a partially overlapping part, but if there are pleats on the peripheral wall, the pleats will spread out and the shape cannot be maintained.
また、周壁面にプリーツを造らずに円形状紙材を金属製
のカップと同じように、プレス型で有底円筒状の蓋に絞
り成形しようとしても、紙は金属に比して伸縮性、塑性
変形がほとんどなく、成形の際、カップ状紙製品は破れ
たり、元の状態に戻ってしまう紙の復元性により形状を
維持することが困難である。In addition, even if you try to draw a circular paper material into a bottomed cylindrical lid with a press mold, just like a metal cup, without making pleats on the surrounding wall, paper is more stretchable than metal. There is almost no plastic deformation, and during molding, cup-shaped paper products tend to tear or return to their original state, making it difficult to maintain their shape due to paper's restorability.
なお、紙を貼り合わせて紙製の有底円筒状の蓋を造って
も、蓋の周壁面が単に平坦であると、摩擦抵抗が少なく
、カップに被せた紙製は滑り落ち易（、上述の問題を解
決することができない。Even if you make a cylindrical paper lid with a bottom by pasting sheets of paper together, if the peripheral wall of the lid is simply flat, there will be little frictional resistance, and the paper covering the cup will easily slip off (as mentioned above). cannot solve the problem.
本発明は、上述の問題点を解決するためになされたもの
で、その目的は、周壁面の摩擦抵抗が大きいカップ状紙
製品を提供するとともに、一体型の構造で、破損が無く
、形状を維持することができるカップ状紙製品の製造方
