  However, it is true that there are various means to display the remaining amount, and there is a demand in the market to differentiate from other containers by displaying the remaining amount different from other containers. Is also true.

  Further, in the case of such a configuration, the slide member may be caught in the middle of dropping, and the remaining amount display may not be visually recognized.

  The object of the present invention is to differentiate from other containers by a display means different from the conventional one, and the display of the remaining amount etc. is surely visually recognized as the contents are discharged. An object of the present invention is to provide a novel liquid ejection container including a movable dish.

  The present invention includes a container body having a mouth portion for filling contents and a lower end of the body portion closed by a bottom member, a pump attached to the mouth portion of the container body, and an operation of this pump. In a liquid ejection container comprising a nozzle head through which an object is taken out and a movable dish that is slidably disposed inside the body of the container body and rises as the contents are taken out, the container is placed on the lower end side of the body of the container body. While providing a see-through area through which the inside of the main body can be seen through, and providing a display visible from the see-through area on the bottom member of the container main body, it is integrally connected to the inside of the container main body via a movable dish and a connecting member. In the state where the suspension member is disposed and the suspension member is disposed at the lower end portion of the trunk portion, the suspension member is blindfolded, and the suspension member is pulled up together with the movable plate to remove the blindfold. To make the display visible. It is characterized in.

  As the display, for example, it is possible to change the color to the display by molding the wall itself standing from the bottom member with colored resin, or by coloring the side of the wall by printing or painting. However, it is also possible to display characters, symbols, etc. on the side surface of the wall erected from the bottom member. Examples of the display attached to the side surface of the wall include, as described above, characters, symbols, figures, colors, or combinations of these as appropriate. Examples of attaching the display include printing, painting, vapor deposition, sticking or mounting of a label or a film. In addition, the color includes not only a single color but also a pattern in which a plurality of colors are combined, including the case of coloring the wall and its side surface raised from the bottom member.
