storage container

Abstract

As shown in the "Reference Drawing," this article is a storage container in which the first and second halves can be expanded and contracted in stages, and the convex portions shown in the "Reference Oblique View of the First Half" and the "Enlarged Reference Oblique View of a Main Part of the First Half" engage with the numerous juxtaposed concave portions shown in the "Reference Oblique View of the Second Half" and the "Enlarged Reference Oblique View of a Main Part of the Second Half," allowing the first and second halves to expand and contract in stages. The slopes on both sides of the protrusions on both sides of the concave portions are asymmetric, and by lifting the first half in an inclined position, the engaged convex portions and concave portions are disengaged. This article is made of synthetic resin.
