The above-mentioned conventional container is provided with a lid part hingedly connected to the upper end of the peripheral wall fitted to the mouth neck part of the container body, and the lid part is pivoted about the hinge. Since the part is provided to open and close above the stopper and the lid must be opened and closed around the hinge, it is difficult to open and close the lid with one hand, and the lid rotates about 180 degrees. If the lid is not provided, the lid easily interferes with the liquid pouring when the container is inverted. Therefore, if the lid is provided as a so-called three-point hinge so that the lid is elastically inverted, the structure becomes complicated. There is a drawback that the cap formed by the peripheral wall and the lid is expensive.

When the liquid in the container is viscous, the liquid can be quickly poured out by normally inverting the container, but when the lid is provided so as to rotate around the hinge, Since the top wall of the lid has a small outer diameter, there is a drawback that it is difficult to place the container body on a table or the like in an inverted state.

According to the present invention, a lid plate is provided so as to be slidable in the front-rear direction on a cap fitted to the upper part of the container body, and the front surface of the lid plate can be closed at the front portion of the lid plate. The disadvantages of the conventional container described above are eliminated by making the upper surface of the base plate attached to the upper surface of the left and right side portions of the upper surface of the cap the mounting surface on the table or the like when the container is inverted. Further, even if the body of the container is squeezed in the inverted state of the container, the high pressure inside the container does not cause the elastic outlet plug to come off from the neck of the container.
