[Problems to be solved by the invention]
The tube container contains a viscous cream-like fluid, and its dispensing is done by squeezing the trunk with the cap removed, but it is poured until the viscous fluid disappears. This is difficult because the elastic deformation of the shoulder portion of the container main body is difficult, and therefore, it is to be discarded while leaving a considerable amount of storage in the shoulder portion.
[0004]
The above disadvantages should be solved by making the nozzle mouth part have a large inner diameter, but in this way, the viscous cream-like product poured out from the nozzle mouth part by pressing the trunk part exceeds the amount used. Therefore, it is impossible to increase the inner diameter.
