2. Description of the Related Art Conventionally, the problems to be solved by the invention
In order to distribute extrudable materials such as miso in a form suitable for domestic use, these materials are contained in bags or containers. A bag made of a plastic film is generally used as a bag used in such an application, and a fixed shape with a plastic lid or a plastic tube is used as a container used in such an application. Can be mentioned.

When the contents are taken out from the fixed-shape container with the lid, the lid is opened and the contents are scraped with a ladle or spoon. On the other hand, when removing the contents from the bag,
The corner or side of the bag is cut out to form an opening, and the bag is pushed from the outside by pressing the bag from the outside. Also, of course, when removing the contents from the tube, the cap of the tube is removed to open the opening,
The tube is extruded through the opening by pressing it from the outside. In this way, in the case of a bag or a tube, the contents can be extruded and taken out, and it is not necessary to use other means as in the case of the fixed shape container with the lid,
It is convenient.

By the way, when the contents are taken out by extrusion as described above, in the initial stage when the amount of contents is relatively large, the pressing for the desired amount of extrusion is relatively easy.
The position of hand compression can be relatively wide,
As the amount of contents becomes smaller and smaller, the pressing operation for extruding the desired amount becomes difficult. At that time, the contents can be extruded by pressing the bag or tube like folding, but such an operation is troublesome, and therefore the contents can be pushed out without pushing the contents to the end. It was sometimes left as it was and discarded.

Therefore, an object of the present invention is to provide a container in which the contents can be taken out until the residual amount becomes extremely small without requiring special labor.
