Abstract
Provided is a double container () configured so that water entrance through an atmospheric air introduction hole () can be reliably prevented and that an adverse effect due to water entrance into an intermediate space () between an outer shell () and an inner bag () can be avoided. The double container () has the outer shell () and the inner bag (). The inner bag () contracts in association with a decrease in contents housed in the inner bag (). The outer shell () is provided with the air introduction hole (). Further, a hydrophobic filter configured to allow air penetration and block water is provided to close the air introduction hole ().
