• a tubular inner container including a cap at an upper portion thereof, the inner container being formed of an easily-breakable material, wherein the inner container includes a shoulder formed in a constricted shape or a tapered shape at the upper portion;
• and
• an outer container mounted so as to extend along a bottom and a trunk towards the shoulder of the inner container such that the shoulder of the inner container is not covered with the outer container, wherein
• an outer peripheral portion of a bottom of the outer container is made thicker than a trunk of the outer container, and a center portion of the bottom of the outer container is made thinner than the outer peripheral portion to form a space such that the center portion of the bottom of the outer container is not brought into contact with the bottom of the inner container,
• the outer container mounted to the inner container and at least the shoulder of the inner container are covered with a heat-shrinkable film, whereby the inner container and the outer container are integrated,
• the outer container is a cushioning container configured to protect the inner container, and
• in a state where a gap is formed between the trunk of the inner container which is located within the cushioning container and an inner wall of the cushioning container which is opposed to the trunk, the inner container and the cushioning container are wrapped with the heat-shrinkable film, wherein the gap extends beyond an upper portion of the outer container and between the heat-shrinkable film and the shoulder of the inner container.
