Next, the effect of this liquid pouring container is demonstrated.
In the liquid dispensing container of the present invention, a creamy liquid is stored as the contents, and the content liquid in the container main body A is sucked up by the pump B by the pressing operation of the nozzle head C and discharged from the nozzle 20. The

In response to the suction of the liquid content, the inside of the container main body A becomes negative pressure, the sliding bottom plate D rises, and the lower side of the sliding bottom plate D in the container main body A from the holding cylinder 30 and the window hole 34 of the bottom lid E. Atmosphere is introduced.
Further, the outer peripheral wall 3 of the container main body A can be visually recognized from the lower end of the elastic peripheral wall 26 of the sliding bottom plate D in the container through the window hole 34 of the bottom cover E of the container from outside the container.

  When the container is distributed or when the content liquid in the container is first used, it is visible from the lower end of the elastic peripheral wall 26 of the sliding bottom plate D in the container through the window hole 34 of the bottom cover E as shown in FIG. The upper end of the body peripheral wall 3 of the container main body A is a layer of the container part A1, but as shown in FIG. 2, when the sliding bottom plate D rises to a certain position, the lower end of the elastic peripheral wall 26 of the sliding bottom plate D Thus, the identification layer part A2 having a different color from the container part A1 can be visually recognized.

  As the sliding bottom plate D rises, the inner surface of the barrel peripheral wall 3 of the container body A that can be visually recognized can be changed from the layer of the container part A1 to the identification layer part A2 of another color at a certain position. When the remaining amount of liquid is low, an identification layer A2 of another color appears, and the remaining amount of content liquid can be confirmed from outside the container.

  In addition, the material of the identification layer A2 is subjected to a gradation that changes the color from the lower part to the upper part, or a scale or a character is printed on the inner peripheral surface of the identification layer part A2, thereby absorbing the content liquid. By raising and raising the sliding bottom plate D, it is possible to change the display of the inner circumference of the trunk wall 3 of the container main body A that can be visually recognized from the outside through the window hole 34 of the bottom lid E, and the liquid dispensing container As an interesting container.
