PROBLEM TO BE SOLVED: To provide a new double container that can eject a content by its own weight, further achieve smooth ejection by squeezing an outer layer body when the remaining amount of the content decreases, and does not cause increase in costs.SOLUTION: A double container 1 comprises an outer layer body 10 that forms an outer shell of the container and an inner layer body 20 that is stored inside the outer layer body 10 and can be freely decreased in volume and deformed. A bottom wall 11 of the outer layer body 10 has a linear rib 14 protruding downward from the bottom wall 11, and a pair of swelling-out parts 15 in which the bottom wall 11 swells out to hold the rib 14 from both sides and then continues to a side face 14a of both sides of the rib 14. In an area sandwiched between the pair of swelling-out parts 15 in an extending direction of the rib 14 there are formed a slit 16 that extends along the extending direction of the rib 14 and penetrates the rib 14 and the bottom wall 11.SELECTED DRAWING: Figure 1 |
