  • Patent number: 5573129
    Abstract: A container is formed for a liquid. In order to reduce a volume of the container for a liquid after use thereof, a bellows portion is provided at an axial direction portion of a container main body. A lid member is removed, and liquid within the container for a liquid is discharged from an opening portion. The bellows portion is contracted so that head space can be adjusted and so that a volume of the container main body can be reduced. Further, because the head space can be adjusted, an interior of the container for a liquid is always substantially filled with the liquid so that oxidation of the liquid can be prevented. When the liquid is poured, the bellows portion automatically expands and contracts so that the liquid flows quickly and so that little air is drawn in. Further, if a certain amount or more of the liquid in the interior is discharged, the volume can be reduced, and a volume-reduced state can be maintained by tightly screwing the lid member.
