[0003]

It is particularly important that the opening and closing of the discharge valve is particularly important in a conventional container for dispensing a cream-like material. The valve was opened by pushing up and closed by elastic restoration of the valve plate, so the opening and closing of the cream-like material was incomplete due to poor fluidity unlike liquid . Further, there is a disadvantage that the length of the cream-like material discharging mechanism portion above the body portion is likely to be larger than the length of the entire container, and furthermore, there is a disadvantage that assembly is not easy. The present invention seeks to solve those problems.
