WIPO Patent Application WO/2019/098734
Kind Code:
A1
Abstract:
The present invention relates to a container device capable of storing and discharging liquid. The container device according to the present invention comprises: a pouch having elastic properties; a hard container having a hard exterior shape compared to the pouch, and having a container opening at one side thereof; a coupling unit coupled to the container opening and coupling an opening of the pouch to the container opening; and an air inlet formed on the hard container or the coupling unit, wherein, when pressure is applied inside the pouch such that the volume of the pouch is increased, the volume of a space present between the pouch and the hard container is reduced as much as a volume increase of the pouch, thereby allowing the air present inside the space to be discharged out of the hard container through the air inlet, and thus the pressure of the space is reduced.
