摘要： Provided is a delamination container that can suppress deformation of container, when a cap is attached thereto, without being provided with a support ring. The present invention provides a delamination container that is provided with a container body provided with an accommodation section for accommodating contents therein and an opening for discharging the contents from the accommodation section. The accommodation section and the opening are provided with an outer layer and an inner layer. In the container body, an inner bag formed of the inner layer contracts as the contents decrease. In the delamination container, the opening is provided with an engagement section to be engaged with a cap, which is to be attached to the opening, and a constriction section that is provided at the accommodation-section side relative to the engagement section and that constricts toward the inner side of the opening. The opening is provided with an upright wall that extends from an outer edge of an upper wall of the constriction section at an angle between 34 degrees and 135 degrees relative to the upper wall. A gap is provided between the inner layer at the upper wall and the inner layer at the upright wall.
