Application container and application tool

An application container capable of containing a medicinal solution, the application container comprising:

• a bottom wall;
• a body section that has a shape standing from an outer edge of the bottom wall, the medicinal solution being contained in a space surrounded by the bottom wall and the body section;
• and
• a mouth section connected to an end portion of the body section on a side opposite to the bottom wall and having an end portion opened in a direction crossing a direction normal to the bottom wall, the end portion of the mouth section being configured to allow an application section to be connected to the end portion of the mouth section, the application section being configured to apply the medicinal solution,
• wherein the body section includes:
• a base portion connected to the bottom wall,
• a reduced diameter portion having a diameter gradually reduced toward the mouth section from the base portion,
• an interposed portion interposed between the reduced diameter portion and the mouth section, and
• a back-side neck portion that interconnects the interposed portion and the mouth section at a position on a side opposite to a side on which the bottom wall is located, across an axis of the mouth section in a direction orthogonal to the axis,
• wherein the body section has a first belly-side boundary between the base portion and the reduced diameter portion on the same side as the side on which the mouth section is opened, the first belly-side boundary having an inner surface curved convexly outward,
• wherein the body section has a second belly-side boundary between the reduced diameter portion and the interposed portion on the same side as the side on which the mouth section is opened, the second belly-side boundary having an inner surface curved convexly inward,
• wherein the mouth section has an inner circumferential surface formed with a curved groove portion between the body section and the application section, the curved groove portion being dented curved convexly outward radially of the mouth section, and coming into contact with the medicinal solution, and
• wherein the groove portion is curved as viewed at a cross-section taken along a direction on which the axis of the mouth section extends.
