Abstract
Description
一方、市場においては、顧客の嗜好性等からさまざまな形状の樹脂製容器が開発されており、大きくは、横断面形状が円形となる円柱状の容器と、横断面形状が略四角形となる四角柱状の容器に分けられる。
本構成のごとく、クッション部の溝の横断面形状の隅部に円弧部を形成することによって、弾性変形時のクッション部の溝における応力集中が生じ難く、当該溝が変形又は破損する虞がない。そのため、上下方向から荷重が加えられても、クッション部が弾性変形してその荷重をより確実に吸収することができる。
本構成のごとく、クッション部の溝の横断面形状における四つの隅部のそれぞれに円弧部を形成することによって、弾性変形時のクッション部の溝における応力集中がより一層生じ難くなる。
本構成のごとく、4つの円弧部のそれぞれが、同じ曲率半径及び弧長を有することによって、クッション部の溝の横断面形状がより円に近いものとなり、弾性変形時のクッション部の溝における応力集中がさらにより一層生じ難くなる。
本構成によれば、上下方向からの荷重がかかった場合に、クッション部を効果的に機能させることができる。
本構成によれば、クッション部の溝である円弧部の円をより真円に近づけることができ、より効率的に荷重を吸収することができる。
特に、横断面形状が長辺、および短辺を有する略長方形の場合、樹脂製容器に横断面形状と略相似形の略長方形のリブを形成しただけでは、上下方向の荷重に対応可能なクッション部とはならない。横断面形状が長方形の樹脂製容器に円弧部を形成することで、より大きな荷重吸収効果を奏する。
