Description
本発明の目的は、ゲート跡が他の物体と接触しにくいケース、および、このケースの製造方法を提供することである。
上記ケースによれば、非接合面に形成されている凹部の深さの寸法が第1の層の厚さの寸法よりも小さい場合よりも、ゲート跡が収容空間からより離れた位置に存在するため、ゲート跡と内容物とがより接触しにくい。このため、内容物がより傷つきにくい。
上記ケースによれば、ゲート跡がケースの外に露出しないため、例えば、ケースが搬送されるときにケースのゲート跡と他の物体とが接触しにくい。このため、ケースが他の物体を傷つけにくい。
容器10は蓋20に面する部分に円形状の開口11を備え、開口11の周方向に沿って雄ねじ12が形成されている。容器10は内容物300を収容する収容空間13を形成する第1の層10A、および、第1の層10Aの外側に積層されている第2の層10Bを備える。第1の層10Aおよび第2の層10Bは射出成形により形成されている。
図3〜図7を参照して、蓋20の製造方法の一例について説明する。
図3に示されるように、第1の工程においては、第1の層30を射出成形するためのコア110とキャビティ120とが組み合わせられる。コア110およびキャビティ120は支持台150により支持される。
ケース1は製造された後、他の物体の一例である他のケースと共に箱に詰められて搬送される。ケース1はゲート跡60がケース1の外に露出していないため、ケース1が搬送されるときにケース1のゲート跡60と他のケースとが接触しにくい。このため、ケース1が他のケースを傷つけにくい。
(1)ケース1はゲート跡60がケース1の外に露出していないため、エンドユーザによりゲート跡60が視認されにくい。このため、ケース1の美観が高められる。
・変形例のケース1によれば、第2の層40の非接合面40Bが第1の層30の内面30Aよりも収容空間23側に突出する、または、第2の層40の非接合面40Bが第1の層30の内面30Aよりも外側に位置する。
・変形例のケース1は、ヘアワックス以外の内容物300を収容する。ヘアワックス以外の内容物300の一例は、リップクリームまたは化粧品である。
