Two-part container, and cap-equipped two-part container

Abstract

A two-part container including: an outer container; and an inner container. The outer container includes a projection formed on an outer surface of a mouth thereof and extends in a circumferential direction. The inner container includes an accommodating portion configured to accommodate contents, an upper-end flange that extends outward from an upper end of the accommodating portion, and a hanging portion that hangs downward from an outer edge end of the upper-end flange. An opening is formed in the hanging portion and the hanging portion includes an engagement piece that elastically deforms within an opening region of the opening in a view from an outer surface of the hanging portion. A part of the engagement piece contacts a lower surface of the projection upon attachment of the inner container to the outer container, thereby preventing release of engagement between the outer container and the inner container.

Dependencies are inferred from the claim text.
