PROBLEM TO BE SOLVED: To easily open a container, prevent contents from spilling out of the container after it is opened and make the container sanitary when it is passed on to the next drinker, by forming a specific opening part in a lid portion adjacent to both side edges and a front edge of a lid opening/closing stopper and providing the lid having a spring member fitted into the interior of the lid opening/closing stopper throughout the entire length thereof and release sheets subjected to the antibacterial treatment, which are superposed on the upper face of the lid opening/closing stopper. SOLUTION: In a lid portion adjacent to both right and left sides and a front edge of a lid opening/closing stopper 3, an opening forming line 7 for defining an opening is formed up to the suitable depth of a lid thickness. Accordingly, by pressing the lid opening/closing stopper 3 downward with a finger, or by biting it down, the opening forming line 7 is cut off, and the opening part comes down slantingly into a container main body 2 together with the lid opening/closing stopper 3 to define the opening. A spring member 4 is fitted into the lid opening/closing stopper 3 throughout the substantially entire length of the stopper 3, and a plurality of, for example, release sheets 5 subjected to the antibacterial treatment are also superposed on the upper face of the stopper 3. Accordingly, when drinking is stopped, the lid opening/closing stopper 3 is returned to the home position by the action of the spring member 4, and the opening is closed. Furthermore, the release sheets 5 subjected to the antibacterial treatment remove an unsanitary feeling when the container is passed on to the next drinker. |
