Abstract
Description
取付機構は、容器本体の周壁に設けられる支持レール部と、容器本体の周壁に設けられるガイド片と、このガイド片に形成される干渉係合部とを含み、ガイド片と干渉係合部とを組み合わせてその前部を二股部に形成し、
搬送部品は、取付機構の支持レール部に支持される部品本体を備え、この部品本体に、流体用の流通口を設けるとともに、取付機構のガイド片に案内される弾性係合片を設け、この弾性係合片を取付機構のガイド片と干渉係合部との二股部に干渉させるようにしたことを特徴としている。
また、容器本体を正面の開口したフロントオープンボックスに形成し、取付機構のガイド片を容器本体の前後方向に向けてその側面には干渉係合部を形成するとともに、ガイド片を容器本体の前後方向に交差する方向に傾斜させ、搬送部品の弾性係合片に、取付機構のガイド片に接触して撓む可撓性を付与し、この弾性係合片には、取付機構の干渉係合部に干渉する突部を形成することができる。
搬送部品の部品本体を中空に形成してその内部には弾性係合片を内蔵し、部品本体の両側部に、取付機構の複数の支持レール部に挟み持たれる被挟持板をそれぞれ形成して各被挟持板の側面を支持レール部の傾斜に沿うよう傾斜させ、部品本体の上部にフランジを形成するとともに、このフランジには、弾性係合片を露出させる操作孔を設け、複数の被挟持板とフランジの少なくともいずれかに流体用の流通口を設けることができる。
搬送部品の部品本体を略台形の板に形成してその両側面を支持レール部の傾斜に沿うよう傾斜させ、部品本体の裏面には弾性係合片を形成し、部品本体に、弾性係合片を露出させる操作孔を設けることができる。
部品本体に、取付機構のガイド片との接触に伴う弾性係合片の過剰な変形を規制する変形規制部を形成することが可能である。
また、部品本体の流通口は、液体や気体等からなる流体が使用される際、この流体を部品本体の内外に円滑に流通させ、搬送部品の洗浄や乾燥作業の作業性を向上させる。
なお、容器本体1の各側壁3には、必要に応じ、マニュアルハンドル4の前部に係止する断面略L字形の複数のストッパ22が間隔をおいて適宜形成される。
本実施形態においても上記実施形態と同様の作用効果が期待でき、しかも、取付機構20や搬送部品30の構成の多様化を図ることができるのは明らかである。
