PROBLEM TO BE SOLVED: To provide a prize case for a bottle container which can be easily detached from the bottle container and can realize an easy plug-opening operation of the bottle container. SOLUTION: In the prize case 10 for the bottle container, a circumferential wall 11 of a cylindrical shape and a top wall 12 at an end are integrated with each other, an opening part 13 to be freely fitted to a bottle cap is formed in a center of the top wall 12, and a prize storage space 14 is formed around a bottle shoulder while the prize case is mounted on the bottle container. A plurality of plug-opening projections 15 which are tightly attached to the edge of the opening part 13 of the top wall 12 to an outer circumferential surface of the bottle cap are provided with a spacing in the circumferential direction when the prize case 10 is upside-down and mounted on the bottle container. A plurality of tongue pieces 16 with adequate elasticity are provided while an edge of the opening part 13 between the plug-opening projections 15 extends substantially parallel to the extending direction of the circumferential wall 11. A locking projection 17 to be attached/detached to/from an open edge of the bottle cap by the elasticity of each tongue piece 16 is provided on a fore end of each tongue piece 16.
