As described above, the container extruder described in this embodiment can be completely pushed out and used up without leaving the shampoo liquid filled in the bag 25, and the empty bag 25 can be used. Since the bag is taken out and replaced with a new bag 25, there is no inconvenience that the contents are mixed even if the maker of the shampoo liquid changes or the type of the product changes. Since only the empty bag 25 needs to be disposed, waste of resources can be eliminated.

Next, the contents pusher of the container according to the second aspect will be described with reference to FIGS. In this embodiment,
Since it has substantially the same configuration as the embodiment shown in FIGS. 1 to 3, the same portions are denoted by the same reference numerals and description thereof will be omitted. That is, in this embodiment, the cylinder portion 6 is not provided in the bottomed cylindrical body 1, and the check valve 29 which allows air to flow only from the outside to the shoulder of the lid 2 from the outside to the shoulder of the lid 2 instead of the flow path 11.

In this embodiment, a vacant space 31 is provided in the middle of the discharge pipe 17, a sphere 32 for opening and closing the lower conduit 17a is sealed in the vacant space 31, and the sphere 32 functions as a check valve. I have. A plurality of small projections 33 are provided on the inner periphery of the upper portion of the empty space 32 so that the spherical body 32 does not block the upper conduit 17b.
Is provided around. In this embodiment, the other structure is the same as that of the embodiment shown in FIGS. 4 to 6, and the bottomed cylinder 1 is formed of a material having restoring elasticity. In this embodiment, the fluid content to be filled in the bag 25 is preferably a fluid content having high fluidity such as soy sauce.

Then, the bag 25 filled with soy sauce is accommodated in the bottomed cylinder 1 and the lid 1 is attached. The soy sauce in the bag body 25 is pushed out from the discharge pipe 17 by sandwiching the body of the bottomed cylindrical body 1 with fingers and pressing the body with the pusher body 5 with the discharge pipe 17 facing downward. At this time, the discharge pipe 17
The spherical body 32 enclosed in the empty space 31 moves to the upper part of the empty space 31 when the discharge pipe 17 faces downward.
Since it is blocked by the third group and separated from the upper conduit 17b and does not block the upper conduit 17b, soy sauce can be discharged from the discharge pipe 17 without any trouble. Then, in a state where the discharge pipe 17 is directed upward, the sphere 32 descends in the empty chamber 31 and closes the lower conduit 17a. Thus, the air is prevented from flowing into the bag 25, and the soy sauce in the bag 25 can be prevented from being oxidized or deteriorated by contact with the air.
