PROBLEM TO BE SOLVED: To provide a double container capable of preventing re-filling of a content.SOLUTION: A double container 1 includes: a container body 2 having an outer layer body 6 with an ambient air introduction hole 5, and an inner layer body 7 arranged inside the outer layer body 6 and storing a content; and a spouting cap 4 which includes a spouting passage of the content and can be attached to/detached from a mouth part 3 of the container body 2. The inner layer body 7 performs volume-reducing deformation as the content spouts, and is introduced between the outer layer body 6 and the inner layer body 7 through the ambient air introduction hole 5. When the spouting cap 4 is attached to the mouth part 3, the ambient air introduction hole 5 becomes in an open state, and when the spouting cap 4 is not attached to the mouth part 3, the ambient air introduction hole 5 becomes in a closed state.SELECTED DRAWING: Figure 1 |
