本発明は絞り型カップとその製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drawable cup and a method for manufacturing the same.
従来の紙カップは内外面とも平滑に構成されているので
強度的に弱く、しかも手で持った場合手が滑り易いとい
う欠点がある。Conventional paper cups have smooth inner and outer surfaces, so they are weak in strength and have the disadvantage that they tend to slip when held.
又アイスクリームのような特殊な内容物の場合は中心部
が堅く、紙カップに接触する面はとけ易いので匙で飲食
する場合とかくアイスクリームが匙で紙カツプ内で回り
、アイスクリームが取りにくいという難点がある。In addition, in the case of special contents such as ice cream, the center is hard and the surface that comes into contact with the paper cup is easily melted, so when eating or drinking with a spoon, the ice cream spins around inside the paper cup with the spoon, making it difficult to remove the ice cream. There are some difficulties.
そこで本発明にあってはカップの表面に複数条の縦凹溝
を絞り形成して前記欠点を解消したものである。Therefore, in the present invention, a plurality of vertical grooves are formed on the surface of the cup to solve the above-mentioned drawbacks.
すなわち本発明は略々中央部において深く末端に行くに
したがって次第に漸減する縦方向の凹溝を胴周に複数条
絞り形成してなる絞り型カップを特定発明とし、略々中
央部において内方に彎曲し、且つその中央部において深
く、末端に行くにしたがって次第に漸減する縦方向の凹
溝な胴周に複数条凹設せる雄金型に対して予め成型され
た紙カップを被嵌し、しかる後前記凹溝に適合した刃厚
を有する分割された複数の雌金型を外方から雄金型に向
って押圧して前記凹溝をカップの胴周に絞り成型するこ
とよりなる前記特定発明の絞り型カップを製造する方法
を第２番目の発明とするものである。That is, the present invention specifies a draw-type cup in which a plurality of vertical grooves are formed around the body circumference, which are deep in the central part and gradually decrease toward the ends; A pre-formed paper cup is fitted into a male mold which is curved and has a plurality of concave grooves in the vertical direction that are deep in the center and gradually decrease towards the ends. The specific invention comprises pressing a plurality of divided female molds having blade thicknesses suitable for the grooves from the outside toward the male mold to form the grooves on the body circumference of the cup. The second invention is a method for manufacturing a squeezable cup.
本発明の特定発明によれば胴周に形成された複数条の縦
凹溝により略々中央部において内方に彎曲した全体とし
てラッパ状を呈するカップが得られると共に内外面に凹
凸が形成されてカップが補強されるのみならず凹凸面に
よって手が滑らす略略中央部が彎曲しているので手に持
ち易いという特徴を発揮できるものであり、アイスクリ
ームのような特殊な内容物のものであっても凹凸面によ
りカップ内で円周方向に移動することがなく、したがっ
て匙を用いて自由に飲食できるという特徴を発揮できる
ものである。According to the specific invention of the present invention, a cup having a trumpet-like shape as a whole curved inward at approximately the center by a plurality of vertical grooves formed on the circumference of the body is obtained, and unevenness is formed on the inner and outer surfaces. Not only is the cup reinforced, but the roughly central part where the hand slides is curved due to the uneven surface, making it easy to hold in the hand. Because of the uneven surface, the cup does not move in the circumferential direction within the cup, and therefore, it is possible to freely eat and drink using a spoon.
しかして第２番目の発明によれば特定発明のカップを連
続的にしかも自動的に多数製造できるという特徴がある
。According to the second invention, however, a large number of cups of the specific invention can be manufactured continuously and automatically.
以下図面に示す実施例について説明する。The embodiments shown in the drawings will be described below.
先づ第１図に基づいて本発明の詳細な説明すると、
１はカップ主体であって紙、プラスチック、金属箔、若
しくはこれらの積層体等で成型されたり或はパルプモー
ルドなどで成形される。First, the present invention will be described in detail based on FIG. 1. Reference numeral 1 is a cup body, which is molded from paper, plastic, metal foil, or a laminate thereof, or by pulp molding.
２は略々中央部が内方に彎曲したカップ主体の胴周を示
すもので、この胴周にはその中央部にお（・て巾Ｓ、深
さｈが大きく末端に行くにしたがって次第に漸減する縦
方向の凹溝３を複数条絞り形成しである。2 shows the body circumference of the main body of the cup, which is approximately curved inward at the center. A plurality of longitudinal concave grooves 3 are formed by drawing.
巾Ｓは縦方向で不変とし深さのみ変化させるようにして
もよい。The width S may be left unchanged in the vertical direction and only the depth may be changed.
なお４はカップ底、５はカップ上縁のカール部をそれぞ
れ示す。Note that 4 indicates the bottom of the cup, and 5 indicates the curled portion of the upper edge of the cup.
以上のようなカップは中央部において内方に向って大き
く彎曲しているので冶もラッパ状を呈する。Since the cup as described above is largely curved inward at the center, it also has a trumpet-like shape.
したがって手に持ち易く凹溝３によって胴周に形成され
る凹凸によって手が滑らないという特徴があり、且つカ
ップが補強される。Therefore, it is easy to hold in the hand, and the unevenness formed on the body circumference by the grooves 3 prevents the hand from slipping, and the cup is reinforced.
次に以上のようなカップの製造方法について第２．３，
