PURPOSE:To provide a container viscous matter which can squeeze out its content completely with a simple handling. CONSTITUTION:The title container for viscous matter is formed of a container body 2 which is made of a flexible and hard resin and has a discharge port 24 with a check valve 26 at its tip end, an inner bag 3 which is made of a soft resin, formed in a similar shape to that of the discharge port 2a side of the container body 2 and mounted inside the container body 2 through an opening flange 31, and a lid 4 which has a check valve 42 and is mounted on an opening of a bottom part of the container body 2. When the container body 2 is pressed by hand to discharge its content and then released from the pressing, the figure of the container body 2 returns to its initial one. Further air flows in through a hole 41 of the lid 4 between the container body 2 and the inner bag 3, here entrance of air through the discharge port 24 can be prevented. By repeating the pressing, the inner bag 3 is made to deform until it is figured along the inside of the discharge port 24 side of the container body 2, whereby the content can be squeezed out completely. |
