1. A double container, comprising: an outer layer body including a tubular dispensing spout and a trunk portion that is contiguous with the dispensing spout, the dispensing spout being provided in a side portion thereof with an air inlet hole extending through the dispensing spout from an inside to an outside thereof; andan inner layer body including an opening, which is contiguous with an opening edge of the dispensing spout, and a content container portion, which is contiguous with the opening, the inner layer body being accommodated in the outer layer body, whereinthe trunk portion included in the outer layer body is provided with an outer-layer-side projecting portion,the inner layer body is provided with an inner-layer-side projecting portion having a shape that corresponds to an inner surface of the outer-layer-side projecting portion,space is provided between the outer-layer-side projecting portion and the inner-layer-side projecting portion,the inner surface of the outer-layer-side projecting portion that faces to a side of the inner layer body has an undercut shape in a longitudinal section thereof in a direction along an axis of the dispensing spout, andthe inner-layer-side projecting portion, in a longitudinal section thereof, has a shape that corresponds to the inner surface of the outer-layer-side projecting portion. 2. The double container of claim 1, wherein the outer-layer-side projecting portion projects toward the inner layer body. 3. The double container of claim 2, wherein the trunk portion includes a bottom portion opposing to the dispensing spout, the bottom portion having a concave shape in which a center side thereof is depressed toward the dispensing spout relative to an outer circumferential edge of the bottom portion, andan outer surface of the outer-layer-side projecting portion that faces to an opposite side to the inner layer body has a concave shape including an inclined surface, which is inclined closer to the dispensing spout as the inclined surface extends further inward of the trunk portion, a flat surface, which is located closer to the dispensing spout relative to the inclined surface and which is perpendicular to the axis of the dispensing spout, and a cut-out surface, which connects the inclined surface and the flat surface and which is depressed toward the dispensing spout relative to the flat surface. 4. The double container of claim 2, wherein an outer surface of the outer-layer-side projecting portion that faces to an opposite side to the inner layer body has a concave shape including a flat surface, which is perpendicular to the axis of the dispensing spout, and a curved surface, which is located closer to the dispensing spout relative to the flat surface and which connects to the flat surface. 5. The double container of claim 1, wherein at least a portion of the outer-layer-side projecting portion is arranged in a range from 60 degrees to 90 degrees from an axis of the air inlet hole in a direction toward a bottom portion included in the trunk portion, in a plan view seen from an axis direction of the air inlet hole. 6. A double container comprising: an outer layer body including a tubular dispensing spout and a trunk portion that is contiguous with the dispensing spout, the dispensing spout being provided in a side portion thereof with an air inlet hole extending through the dispensing spout from an inside to an outside thereof; andan inner layer body including an opening, which is contiguous with an opening edge of the dispensing spout, and a content container portion, which is contiguous with the opening, the inner layer body being accommodated in the outer layer body, whereinthe trunk portion included in the outer layer body is provided with an outer-layer-side projecting portion,the inner layer body is provided with an inner-layer-side projecting portion having a shape that corresponds to an inner surface of the outer-layer-side projecting portion,space is provided between the outer-layer-side projecting portion and the inner-layer-side projecting portion,the outer-layer-side projecting portion comprises an outer layer rib extending in a direction from the dispensing spout to a bottom portion,an inner surface of the outer layer rib that faces to the side of the inner layer body has an undercut shape in a transverse section thereof, andthe inner-layer-side projecting portion comprises an inner layer rib that, in a transverse section thereof, has a shape corresponding to the inner surface of the outer layer rib. 7. The double container of claim 6, wherein the outer layer rib, in a transverse section thereof, has a U-shape including a pair of side wall portions and a ceiling wall portion that connects the pair of side wall portions, and an outer surface of the outer layer rib that faces to an opposite side to the inner layer body, in a transverse section thereof, has a shape including a pair of outer surfaces of the side wall portions having linear portions which is in parallel with each other, and an outer surface of the ceiling wall portion having a connecting side portion which connects the pair of linear portions. 8. The double container of claim 7, wherein the trunk portion of the outer layer body is further provided with a sub-outer layer rib that is adjacent to the outer layer rib, and an outer surface of the sub-outer layer rib that faces to the opposite side to the inner layer body, in a transverse section thereof, has a shape including an inclined side, which connects to the linear portion of the outer layer rib and which is inclined relative to the linear portion. 9. The double container of claim 8, wherein in the transverse section, the linear portion of the outer layer rib extends substantially in parallel with a line that passes a widthwise middle point of the sub-outer layer rib and that also passes an axis of the dispensing spout. 10. The double container of claim 6, wherein at least a portion of the outer layer rib is arranged in a range from 60 degrees to 90 degrees from an axis of the air inlet hole in a direction toward the bottom portion, in a plan view seen from an axis direction of the air inlet hole. 11. The double container of claim 6, wherein the outer layer rib and the inner layer rib are arranged in an area extending in the range of a central angle of 90° downward from the air inlet hole. 12. The double container of claim 11, wherein the outer layer rib is provided in plurality, and the plurality of outer layer ribs comprise at least four outer layer ribs, andtwo areas, one each on left and right sides, determined by excluding an area extending in the range of a central angle of less than 60° downward from the air inlet hole, from the area extending in the range of a central angle of 90° downward from the air inlet hole, communicate to areas defined between two outer layer ribs in pair.
