Abstract: A plastic container includes a molded multi-layered structure defining an inner space therein and including a first molded layer surrounding the inner space and having an outer surface and an outer protrusion protruding outwardly from the outer surface, and a second molded layer surrounding and covering the outer surface of the first molded layer and formed with an outer through-hole. The outer protrusion of the first molded layer fills and seals the outer through-hole in the second molded layer.

Abstract: A container includes: a transparent surrounding wall having an inner wall surface defining an accommodation space of the container, and an outer wall surface that is formed with a plurality of refractive regions, each of which is concave inwardly toward the inner wall surface; and an opaque surrounding medium covering one of the inner and outer wall surfaces of the transparent surrounding wall, and formed with a plurality of through-holes, each of which is aligned with a respective one of the refractive regions of the outer wall surface so as to permit passage of light therethrough.
