However, a outside air enters an inner part of the bottle 1 through the small hole 2a because a vacuum in the inner space a of the bottle become larger than that in an outside space, that is, a vacuum pressure of the inner space of the bottle become larger than an atmospheric pressure.
That is, when the inner space a of the bottle becomes the same atmospheric pressure as the outside space b, it is possible to discharge the content of the bottle, and thus a volume of the inner space increases by the discharged amount to be a vacuum pressure, so that an operation moving air from the outer space b is repeatedly occurs.
Therefore, the content can not be discharged quickly due to a repetitive operation of discharge of the content and an inflow of the outside air through one a small hole 2a and pouring the content quantitatively is obstructed due to a air bubble being produced within the bottle.
Even though the bottle is tilted to discharge the content, a residual content remains between the inner cap 2 and the bottle 1.
In order to discharge the residual content, it is disadvantage that the inner cap 2 should be separated.
