Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案はブロー成型容器に係り、特に補強面を形成して
強度を向上させたものに関する。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a blow-molded container, and more particularly to a container in which a reinforcing surface is formed to improve strength.
一般に、ブロー成型容器は胴部が肉薄となるため、その
胴部に周辺が他の面と段差を有する補強面を複数個所定
の間隔を以て形成し、強度を向上させるようにしてあ
る。In general, since the body of a blow-molded container is thin, a plurality of reinforcing surfaces are formed around the body at a predetermined distance from other surfaces so as to improve the strength.
このようなものとしては、例えば実開昭57-199511号公
報に記載されているものがあり、第４図に示すように、
凹部で縁どった補強面３を角型胴部の周囲に４箇所設
け、胴部を補強するようになっている。As such a thing, for example, there is one described in Japanese Utility Model Publication No. 57-199511, and as shown in FIG.
Reinforcing surfaces 3 framed by the recesses are provided at four places around the rectangular body to reinforce the body.
しかし、前記した従来のものにおいては、胴部の強度は
向上するが、強度的な不連続性が生じて局部的に強度不
足の部分が発生することがある。However, in the above-mentioned conventional one, although the strength of the body portion is improved, a discontinuity in strength may occur and a portion with insufficient strength may locally occur.

ブを形成した部分と肩部との境目等に集中することがあ
る。That is, when the contents are filled in the container, the juice or the like may be heated for sterilization, but in this case, when the contents are cooled, the internal pressure is lowered and a force for deforming the container is generated. This force may be concentrated on a portion where the strength of the container suddenly changes, for example, a boundary between a rib-formed portion and a shoulder portion.
このため当該部分が座屈しこれが全体に波及して大きな
変形に至る場合がある。For this reason, the part may buckle, which may spread to the whole and cause large deformation.
本考案は前記事項に鑑みてなされたもので、筒状に形成

上させることができるようにしたブロー成型容器を提供
することを技術的課題とする。The present invention has been made in view of the above-mentioned matters, and in the case where a plurality of reinforcing surfaces having a step difference with other surfaces are formed at a predetermined interval on a cylindrical body portion, the strength distribution of the container It is a technical object to provide a blow-molded container in which the strength of the entire container can be improved by reinforcing the portion where the temperature suddenly changes.
本考案は前記技術的課題を解決するために、以下のよう
な構成とした。The present invention has the following configuration in order to solve the above technical problems.
即ち、筒状に形成した胴部２に、その周辺が他の面と段
差を有する補強面３を所定の間隔を以て複数個形成す
る。That is, a plurality of reinforcing surfaces 3 having a step difference with other surfaces around the periphery of the barrel-shaped body 2 are formed at predetermined intervals.
これにより各補強面３の間に縦長面４を形成する。Thereby, the vertically long surface 4 is formed between the reinforcing surfaces 3.
この縦長面４の両端部分に凹所５を夫々形成してブロー
成型容器とした。Recesses 5 were formed at both ends of the vertically long surface 4 to obtain a blow molded container.
縦長面４の両端部分に凹所５を夫々形成することによ
り、容器の強度が急変する部位を補強することができ
る。By forming the recesses 5 at both end portions of the vertically long surface 4, it is possible to reinforce the portion where the strength of the container suddenly changes.
本考案の実施例を第１図ないし第３図に基づいて説明す
る。An embodiment of the present invention will be described with reference to FIGS.
容器本体１はポリエチレンテレフタレート（PET）製の

３は第２図に示すように、胴部２の基準面に対して凹ま
せて凹部3aを形成するとともに、この凹部3aの中央部分
を胴部２の基準面付近にまで隆起させて凸部3bを形成し
たものである。The container body 1 is formed by blow molding a preform made of polyethylene terephthalate (PET), and a cylindrical body portion 2 has a reinforcing surface 3 having a step difference from other surfaces around the body portion 6 at a predetermined interval. Individually formed. As shown in FIG. 2, the reinforcing surface 3 is recessed from the reference surface of the body portion 2 to form a recessed portion 3a, and the central portion of the recessed portion 3a is raised up to near the reference surface of the body portion 2. To form the convex portion 3b.
これにより各補強面３の間に６本の縦長面４が形成され

ようにしてある。As a result, six vertically long surfaces 4 are formed between the reinforcing surfaces 3. This vertically long surface 4 serves as a reference surface for the body portion 2,
As shown in FIG. 3, recesses 5 are formed at both ends thereof. The recess 5 has an oval shape, and its major axis is set to about 1/8 of the height of the reinforcing surface 3. The recess 5 is located slightly outside the line connecting the upper and lower ends of each reinforcing surface 3 so as to reinforce the portion where the strength distribution of the container suddenly changes.
このように、内容物充填後に内圧が降下して応力が局部
的に集中しても、容器の変形を最小限に抑えることがで
きる。In this way, even if the internal pressure drops and the stress is locally concentrated after filling the contents, the deformation of the container can be minimized.

ことができた。According to the present invention, the vertically long surface 4 is formed between the plurality of reinforcing surfaces 3 formed on the body, and the recesses 5 are formed at both end portions of the vertically long surface 4, respectively. It was possible to reinforce the insufficient portion and improve the strength of the entire container.
