PROBLEM TO BE SOLVED: To provide a liquid container made of a resin which can reduce a liquid remaining amount in the container after discharging of the liquid by pressing, and can easily discharge a specified amount of the liquid by one pressing.SOLUTION: A liquid container made of a resin includes: an internal bag section made of a resin which houses the liquid inside, and is elastically deformable a mouth section for discharging of the liquid which is integrally provided in a manner to communicate with the inside of the internal bag section and an outer shell section made of resin which covers part or whole of the outside of the internal bag section with a specified gap, and is elastically deformable. The gap between the internal bag section and the outer shell section is filled with a gas or a liquid and the gap is sealed. When the external wall surface section of the outer shell section is pressed from the outside, the liquid housed in the internal bag section is discharged from the mouth section in the liquid container made of resin. The internal bag section has a flat shape, and each of the cross sections in the vertical direction when the flat surface is placed to be horizontal forms an approximately spindle-like shape.COPYRIGHT: (C)2013,JPO&INPIT【課題】 押圧による液体排出後の容器内の液体残量を低減し、一度の押圧で容易に所定容量の液体を排出することが可能な樹脂製液体容器を提供する。【解決手段】 内部に液体を収容する弾性変形可能な樹脂製の内袋部と、該内袋部の内部と連通して一体に設けられた液体排出用の口部と、該内袋部の一部又は全部の外側を所定の間隙を有して覆う弾性変形可能な樹脂製の外殻部とを有し、該内袋部と該外殻部との間隙において気体又は液体が充填・密封されており、該外殻部の外壁面部分が外側から押圧されることによって該内袋部内に収容された液体が該口部から排出する樹脂製液体容器であって、前記内袋部が扁平状であり、且つ扁平面を水平に置いた際の垂直方向の断面がいずれも略紡錘形状をなしていることを特徴とする樹脂製液体容器【選択図】 図1
