## Abstract

Provided is an application container including a bottom wall, a body section, and a mouth section. The body section includes a base portion, a reduced diameter portion, an interposed portion interposed between the reduced diameter portion and the mouth section, and a back-side neck portion interconnecting the interposed portion and the mouth section at a position opposite to the bottom wall across an axis of the mouth section in a direction orthogonal to the axis. An inner surface of the first belly-side boundary between the base portion and the reduced diameter portion has a shape curved convexly outward. An inner surface of the second belly-side boundary between the reduced diameter portion and the interposed portion has a shape curved convexly inward.

## Claims

### Claim 1

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.

### Claim 2

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; and
a mouth section connected to an end portion of the body section on a side opposite to the bottom wall, the mouth section being opened in a direction crossing a direction normal to the bottom wall,
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 base portion includes a back-surface finger receiving portion formed on a side opposite to a side on which the mouth section is opened,
wherein the back-surface finger receiving portion has a shape projecting outward radially of the base portion and is adjacent to the bottom wall,
wherein the back-surface finger receiving portion has a back-surface lower overhang surface that is contactable to a placing surface,
wherein the back-surface lower overhang surface is radially positioned outside an outer edge of the bottom wall, and
wherein the back-surface finger receiving portion is the most radially outward portion of the container.

### Claim 3 (depends on 1)

The application container according to claim 1, wherein
the base portion includes a pair of side-surface finger receiving portions that are formed on opposite sides of the base portion in a direction orthogonal to a direction joining the side on which the mouth section is opened and a side opposite thereto, each of the side-surface finger receiving portions having a shape projecting outward or dented inward radially of the base portion.

### Claim 4 (depends on 3)

The application container according to claim 3, wherein
the pair of the side-surface finger receiving portions have respective shapes projecting outward radially of the base portion and
the pair of the side-surface finger receiving portions have respective side-surface lower overhang surfaces that are contactable to a placing surface outside an outer edge of the bottom wall radially of the base portion.

### Claim 5 (depends on 1)

An application tool comprising:
the application container according to claim 1; and
an application section configured to be connected to the mouth section of the application container and being capable of applying a medicinal solution in the application container.
