A bottle container is provided with: an inner container (2), the upper part of which is provided with a lid, which has a cylindrical form and is formed from a material that breaks easily; and an outer container (3), which is fitted so as to conform to the body (5) and the bottom (6) of the inner container (2). The upper part of the inner container (2) is formed as a shoulder section (8) with a narrowed or tapered form that is not covered by the outer container (3). The perimeter (13b) of the bottom (13) of the outer container (3) is made to be thicker than the thickness of the side wall (14) of the outer container (3). The central section (13a) of the bottom (13) of the outer container (3) forms a space (13c) that does not contact the bottom section (6) of the inner container and the thickness is made to be thinner than the perimeter (13b). The outer container (3) fitted on the inner container (2) and at least the shoulder section (8) of the inner container (2) are covered with a heat-shrinkable film (4) to unify the inner container (2) and the outer container (3). As a result, a bottle container, which has a bottle breakage-preventing function for preventing bottle breakage due to impact on the bottom or body of the bottle container, etc. is provided.
