Abstract

A discharging container comprising a container body that stores a content and a discharging component that discharges the content. The discharging component comprises a cover portion mounted to a mouth neck portion of the container body and a pump head portion that discharges the content by a pressing operation. A tubular guide rod is erected upwards from the periphery of an opening formed in the central portion of a top plate of the cover portion. The pump head portion is provided with an inner waterproof wall capable of moving up and down along the outer peripheral surface of the guide rod, and a first outer waterproof wall located at the outer side of the inner waterproof wall. The discharging container is easy to be manufactured and can reliably prevent water intrusion.

First claim

The invention claimed is:

1. A discharging container, comprising a container body for storing a content and a discharging component that discharges the content, wherein:
the discharging component comprises a cover portion mounted to a mouth neck portion of the container body and a pump head portion that discharges the content by a pressing operation,
a tubular guide rod is erected upwards from a periphery of an opening formed in a central portion of a top plate of the cover portion,
the pump head portion is provided with an inner waterproof wall capable of moving up and down along an outer peripheral surface of the guide rod, and a first outer waterproof wall located at the outer side of the inner waterproof wall, and
in a state that the pump head portion is pressed, the inner waterproof wall is opposed to the guide rod, a space between the inner waterproof wall and the guide rod is communicated with a space between the inner waterproof wall and the first outer waterproof wall via a first opening formed in the inner waterproof wall, and a space between the inner waterproof wall and the first outer waterproof wall is communicated with external air via a second opening formed in the first outer waterproof wall and/or a third opening formed in a top wall of the pump head portion.

2. The discharging container according to claim 1 , wherein
a lower end edge of the inner waterproof wall and a lower end edge of the first outer waterproof wall are both located at the same position as the position of an upper end edge of the guide rod in a height direction of the discharging container or below the position of an upper end edge of the guide rod in a height direction of the discharging container.

3. The discharging container according to claim 1 , wherein
at least any one of the first opening, the second opening, and the third opening is formed as two or more openings.

4. The discharging container according to claim 1 , wherein
when viewed along a height direction of the discharging container, the first opening and the second opening and/or the third opening do not overlap each other in a circumferential direction, respectively.

5. The discharging container according to claim 1 , wherein the first opening is formed to extend upwards from a lower end edge of the inner waterproof wall.

6. The discharging container according to claim 1 , wherein the first opening has an elongated shape.

7. The discharging container according to claim 1 , wherein the second opening is formed to extend upwards from a lower end edge of the first outer waterproof wall.

8. The discharging container according to claim 1 , wherein the second opening has an elongated shape.

9. The discharging container according to claim 1 , wherein the third opening is formed into an arc shape when viewed along a height direction of the discharging container.

10. The discharging container according to claim 1 , wherein
a convex first baffle is arranged on an outer peripheral surface of the inner waterproof wall, and
a convex second baffle is arranged on an inner peripheral surface of the first outer waterproof wall.

11. The discharging container according to claim 1 , wherein
the content is a liquid agent, and
the discharging container is a foam discharging container that mixes the liquid agent with air to discharge a foamy liquid agent.

12. The discharging container according to claim 2 , wherein
when viewed along the height direction of the discharging container, the first opening and the second opening and/or the third opening do not overlap each other in a circumferential direction, respectively.

13. The discharging container according to claim 2 , wherein the first opening is formed to extend upwards from the lower end edge of the inner waterproof wall.

14. The discharging container according to claim 2 , wherein the first opening has an elongated shape.

15. The discharging container according to claim 2 , wherein the second opening is formed to extend upwards from the lower end edge of the first outer waterproof wall.

16. The discharging container according to claim 2 , wherein the second opening has an elongated shape.

17. The discharging container according to claim 2 , wherein the third opening is formed into an arc shape when viewed along the height direction of the discharging container.

18. The discharging container according to claim 2 , wherein
a convex first baffle is arranged on an outer peripheral surface of the inner waterproof wall, and
a convex second baffle is arranged on an inner peripheral surface of the first outer waterproof wall.

19. The discharging container according to claim 2 , wherein
the content is a liquid agent, and
the discharging container is a foam discharging container that mixes the liquid agent with air to discharge a foamy liquid agent.
