With the upper lid C closed to the cap body B, the sliding and closing lids are in a state where the closed-direction inner peripheral spiral portion 58 of the shaft operating recess 56 meshes with the closed-direction outer peripheral spiral portion 48 of the rotating shaft 45. Can be stopped.
Further, the meshing between the open-direction inner peripheral spiral portion 57 on the right side of the shaft operating recess 56 and the open-direction outer peripheral spiral portion 47 of the rotating shaft 45 is completely disengaged, and the pitch is stopped at a position shifted by 90 °.
At the same time as the end of the slide, the locking protrusion 55 of the slide wall 50 of the slide button D engages with the left locking recess 17 provided in the straight wall portion 16 of the front outer wall portion 9 of the main body portion B1, and a click feeling is felt. At the same time, the engagement between the locking protrusion 55 and the left locking recess 17 becomes a resistance, and the closed state is maintained.

When the top lid C is closed, the respective insertion plugs 43 of the top wall 40 of the top lid C are fitted into the respective swing holes 35 of the top surface 30 of the top wall portion B3 and sealed.
Further, the outer periphery of the right push button 52 and the left push button 51 of the upper lid C and the slide button D are flush with each other with respect to the outer periphery of the cap body B, and the connecting piece 46 of the hinge shaft portion 42 of the upper lid C is the cap body B. Since it is housed in the groove portion 23 and the groove portion 34 provided in the main body portion B1 and the top wall portion B3 on the back side of the above, it becomes a circular shape with no protruding portion when viewed from above, and not only looks good, but also the container is tilted down. At that time, it is possible to prevent the protruding slide button D from being pushed in and inadvertently opened.

When the cap of this embodiment is viewed from above, when the upper lid C is closed, the outer circumferences of the right push button 52 and the left push button 51 of the upper lid C and the slide button D are flush with each other with respect to the outer circumference of the cap body B. In the state of opening the lid or in the process thereof, the front side of the upper lid C faces upward, and the right push button 52 of the slide button D protrudes to the right with respect to the outer circumference of the cap body B. It will be easier to check and you will be able to know for sure.

Further, since the upper lid C can be opened and closed with respect to the cap main body B by sliding the slide button D with respect to the cap main body B, a finger or the like touches the upper surface of the upper lid C and the top wall portion B3 of the cap main body B at the time of opening and closing. It is hygienic because it never happens.

In the cap of the present invention, one of the slide buttons can be pushed against the cap body to project the other to open the top lid, and the other of the protruding slide buttons can be pushed back to close the top lid. Therefore, the opening and closing operation of the upper lid is easy, and the inside of the container can be kept clean without touching the upper lid or the top wall portion with fingers or the like.
In addition, the content is not limited to granular and powdery foods, but can also be applied to liquid foods, and in particular, as a container for storing seasonings and the like that require the top lid to be opened with one hand during cooking. Suitable.
