Abstract

An application container includes a main body cylinder, an application tool, and an engagement portion. The main body cylinder has a first end and a second end opposite the first end. The application tool is insertable into the main body cylinder through the first end of the main body cylinder. The engagement portion is positioned within the main body cylinder, and includes a cylindrical portion to connect with the application tool and a connector that connects the cylindrical portion and the main body cylinder. The cylindrical portion of the engagement portion is spaced apart from the main body cylinder.

First claim

What is claimed is:

1. An application container comprising:
a main body cylinder having an opening and an inner surface extending in an axial direction;
an engagement portion located inside the main body cylinder, the engagement portion including:
a cylindrical portion that extends in the axial direction, wherein the cylindrical portion includes an inner peripheral surface, and an outer peripheral surface opposite the inner peripheral surface, wherein the outer peripheral surface of the cylindrical portion is spaced apart from the inner surface of the main body cylinder; and
a connector joining the main body cylinder with the cylindrical portion of the engagement portion; and

an application tool at least partially insertable into the main body cylinder through the opening of the main body cylinder to engage with the engagement portion, wherein the application tool includes:
an engagement target portion to engage the inner peripheral surface of the cylindrical portion of the engagement portion;
a flange portion that extends from the engagement target portion, wherein the flange portion has a diameter that is greater than a diameter of the engagement target portion to contact the connector of the engagement portion; and
a middle cylinder to engage with the main body cylinder in the axial direction, wherein the flange portion is interposed between the middle cylinder of the application tool and the connector of the engagement portion, in the axial direction, when the engagement target portion of the application tool is positioned in the cylindrical portion of the engagement portion.

2. The application container according to claim 1 ,
wherein the application tool farther includes an application material and an application material holder configured to support the application material, wherein the application material holder is displaceable in the axial direction of the main body cylinder to feed the application material away from the main body cylinder.

3. The application container according to claim 1 ,
wherein the application tool is a first application tool positioned at a first end of the main body cylinder through the opening, and wherein the main body cylinder includes a second end opposite the first end, and
wherein the application container further comprises a second application tool located at the second end of the main body cylinder.

4. The application container according to claim 3 ,
wherein the main body cylinder has an outer diameter that increases from the first end toward the second end,
wherein the opening is a first opening located at the first end, and the main body cylinder includes a second opening at the second end,
wherein the first application tool includes a first application material,
wherein the application container further comprises a container portion attachable to the second opening of the main body cylinder,
wherein the container portion contains a second application material to be applied by the second application tool, and
wherein a maximum outer diameter of the container portion is greater than a maximum outer diameter of the main body cylinder.

5. The application container according to claim 1 , wherein the connector extends along a radial direction of the main body cylinder.

6. The application container according to claim 5 , wherein a wall thickness of the connector is equal to or less than 60% of a wall thickness of the main body cylinder.

7. The application container according to claim 1 ,
wherein the inner peripheral surface of the cylindrical portion has ridges that are spaced apart in a circumferential direction of the inner peripheral surface of the cylindrical portion and that extend in the axial direction of the cylindrical portion to engage into rotation with the engagement target portion of the application tool.

8. The application container according to claim 7 ,
wherein the engagement target portion of the application tool extends along a longitudinal axis of the application tool, and includes a protruding portion which is elastic in a radial direction relative to the longitudinal axis of the application tool,
wherein the ridges of the inner peripheral surface of the cylindrical portion are configured to engage into rotation with the protruding portion of the engagement target portion, and
wherein the protruding portion is configured to disengage from the ridges, when a rotational force of the application tool with respect to the main body cylinder exceeds a threshold value.

9. An application container comprising:
a main body cylinder having a first end that forms an opening, a second end opposite the first end in an axial direction of the main body cylinder, and an inner surface extending between the first end and the second end;
an engagement portion positioned within the main body cylinder, the engagement portion including:
a cylindrical portion that is spaced apart from the inner surface of the main body cylinder; and
a connector that extends between the cylindrical portion and the main body cylinder; and

an application tool at least partially insertable into the main body cylinder through the opening of the main body cylinder to engage with the engagement portion, wherein the application tool includes:
an engagement target portion to engage an inner peripheral surface of the cylindrical portion of the engagement portion;
a flange portion that extends from the engagement target portion, wherein the flange portion has a diameter that is greater than a diameter of the engagement target portion; and
a middle cylinder that is insertable into the main body cylinder in the axial direction, to abut the flange portion so as to interpose the flange portion between the middle cylinder of the application tool and the connector of the engagement portion in the axial direction, when the application tool is engaged with the engagement portion.

10. The application container according to claim 9 , wherein the application tool comprises a holding member that includes the engagement target portion and the flange portion, and wherein the middle cylinder includes an end surface to contact the flange portion of the holding member.

11. The application container according to claim 9 , wherein the connector of the engagement portion extends substantially orthogonally with respect to axial direction of the main body cylinder, to limit a displacement of the application tool in the axial direction when the flange portion of the application tool contacts the connector.

12. The application container according to claim 9 , wherein the engagement target portion has a length that is no longer than a length of the cylindrical portion of the engagement portion, to position a longitudinal end of the application tool formed by the engagement target portion within the cylindrical portion when the flange portion of the application tool contacts the connector of the engagement portion.

13. The application container according to claim 9 , wherein the engagement target portion of the application tool has an outer surface to engage slidably in the axial direction, with an inner surface of the cylindrical portion.

14. The application container according to claim 9 , wherein the application tool further includes an application material holder to hold an application material, and a screw coupling located between the flange portion and the application material holder to displace the application material relative to the main body cylinder in the axial direction.

15. The application container according to claim 9 ,
wherein the opening of the main body cylinder forms a first open
