【発明の詳細な説明】
(産業上の利用分野)
この発明は、ポリエチレン、ポリプロピレン、塩化ビニ

ゆる深物容器を製造する方法に関するものである。Detailed Description of the Invention (Field of Industrial Application) This invention is a method for producing drinks such as juice and other products by vacuum or pressure forming using thermoplastic synthetic resin sheets such as polyethylene, polypropylene, and vinyl chloride. The present invention relates to a method for manufacturing a so-called deep container, which has a larger length in the vertical direction than its inner diameter.
(従来の技術)
一般に深物容器の製造は、第6図に示すように、加熱装
置14で軟化させた熱可塑性の合成樹脂シート13を、
雌金型11と雄金型(プラグ)11′とを具備する真空
(又は圧空)成形機12により成形したのち、図外打抜
機で個々の製品に打ち抜いて製造していた。(Prior Art) In general, in the manufacture of deep containers, as shown in FIG. 6, a thermoplastic synthetic resin sheet 13 softened by a heating device 14 is
After molding with a vacuum (or pressure air) molding machine 12 equipped with a female mold 11 and a male mold (plug) 11', the product is manufactured by punching into individual products using a punching machine (not shown).
(発明が解決しようとする問題点)
この方法では、雌雄1組の金型を必要とするため金型化
が嵩むうえ、シート厚が0.5〜1.Ovaのものを必
要とするので、加熱時間かがかる欠点があった。(Problems to be Solved by the Invention) This method requires a pair of male and female molds, which increases the amount of molding required, and the sheet thickness is 0.5 to 1.5 mm. Since OVA is required, there is a drawback that the heating time is long.
又、平らなシートを、内径に対して深物容器の深さだけ
、大きく上下方向に延伸させる結果、容器の側部の肉厚
が不均一になるのを避けられながった。したがって、成
形が非常に困難で、しがち製品の不良率が極めて高い欠
点があった。Furthermore, as a result of stretching the flat sheet in the vertical direction by the depth of the deep container with respect to the inner diameter, it has become impossible to avoid uneven wall thickness on the sides of the container. Therefore, it is very difficult to mold, and the defect rate of products tends to be extremely high.
(問題点を解決するための手段)
そこでこの発明は、従来の製造方法の欠点を解消するこ
とを目的とするものである。(Means for Solving the Problems) Therefore, it is an object of the present invention to eliminate the drawbacks of the conventional manufacturing methods.
即ち、深物容器の側部に上下方向の連結部を残して、側
部から底部を連続して切り開き、連結部を軸として左右
対称に展開した形状に、側部及び底部を雌金型により真
空又は圧空成形した熱可塑性合成樹脂シートを、前記展
開した形状に打ち抜いたのち、連結部を軸として内側へ
折り曲げて、対向する切り開き口を接着することを要旨
とするものである。In other words, the bottom part is continuously cut out from the side part, leaving a vertical connection part on the side of the deep food container, and the side part and the bottom part are molded with a female mold into a shape that is developed symmetrically with the connection part as an axis. The gist of this method is to punch out a vacuum- or pressure-formed thermoplastic synthetic resin sheet into the expanded shape, then bend it inward around the connecting portion, and adhere the opposing incisions.
(作用)
シートを、連結部を軸として展開した形状に成形するた
め、内径の半分だけ絞ればよいので、従来に比し浅い絞
りが可能となり、厚みの薄いシートで均一に成形できる
。(Function) Since the sheet is formed into an expanded shape with the connecting portion as the axis, it is only necessary to squeeze half of the inner diameter, so it is possible to draw shallower than before, and a thin sheet can be formed uniformly.
成形後は、連結部を軸として内側へ折り曲げ、対向する
切り開き口を接合して、熱接着などの手段で接着すれば
、所望の深物容器を製造できる。After molding, the desired deep container can be manufactured by bending the container inward around the connecting portion, joining the opposing openings, and bonding by heat bonding or other means.
(効果)
絞りが浅いため、雌金型のみで成形でき、金型化が半減
する。又、0.3鶴程度の薄いシートで成形できるので
、短時間で加熱でき、シート化、電力費の節減が可能と
なる。さらに側部の肉厚を均一に成形できる結果、製品
の不良率がなくなる。(Effects) Because the aperture is shallow, it can be formed using only a female mold, reducing the amount of molding by half. In addition, since it can be formed into a thin sheet of about 0.3 mm, it can be heated in a short time, making it possible to form a sheet and reduce electricity costs. Furthermore, the side wall thickness can be molded to be uniform, which eliminates product defect rates.
しかも、従来の深物容器では、曲面印刷機を用いなけれ
ば側部に印刷することができなかったが、て成形できる
。Furthermore, with conventional deep containers, it was not possible to print on the sides without using a curved surface printing machine, but it can be molded by hand.
従来方法では、把手付きの深物容器は製造できなかった
が、この方法では容易に製造できる。With conventional methods, deep containers with handles could not be manufactured, but with this method, they can be manufactured easily.

側部を連結部5として残したものである。As shown in FIG. 1, the deep food container 1 in the unfolded shape extends left and right from the side 2 to the bottom 3 along the central longitudinal section (i.e., plane of symmetry) passing through the handle 4 of the product deep food container A. It is cut out symmetrically, leaving the side opening 6 and the side portion radially opposite the side portion as the connecting portion 5.
