Abstract

A foam discharge container is a foam discharge container for discharging foam in response to a pushing operation, and includes a discharge port which is opened in a direction opposite to a pushing direction of the pushing operation and discharges foam, and a pushing portion that keeps the distance between a discharge target body receiving foam and the discharge port constant.

First claim

The invention claimed is:

1. A foam discharge cap that is used while mounted on a container main body storing a liquid agent and discharges foam in response to a pushing operation, the foam discharge cap comprising:
a discharge port that is opened in an opposite direction of a pushing direction of the pushing operation and discharges the foam; and
a pushing portion that keeps a distance between a discharge target body receiving the foam and the discharge port constant, wherein
the discharge port is an opening at a tip of a nozzle forming wall standing in the opposite direction,
the pushing portion is an annular standing wall that surrounds a periphery of the discharge port and stands in the opposite direction beyond the discharge port,
the annular standing wall has an opening at a tip thereof in the opposite direction, and
there are no obstacles between the discharge port and the opening of the annular standing wall.

2. The foam discharge cap according to claim 1 , wherein
the pushing portion has a standing portion standing at a position which is away from the discharge port in an outward direction, and
the pushing portion has an intercommunicating portion which communicates an inside region and an outside region of the pushing portion with each other.

3. The foam discharge cap according to claim 1 , comprising:
a primary discharge port that discharges the foam;
an anterior chamber in which the foam discharged from the primary discharge port spreads in an internal space; and
a facing portion that is arranged so as to face the primary discharge port with the anterior chamber interposed between the facing portion and the primary discharge port and has the discharge port formed in the facing portion.

4. The foam discharge cap according to claim 3 , wherein, when the foam discharge cap is viewed in the pushing direction, the facing portion covers at least a part of the primary discharge port.

5. The foam discharge cap according to claim 3 , wherein
the facing portion is configured to include a protruding portion protruding toward the primary discharge port, and
when the foam discharge cap is viewed in the pushing direction, the protruding portion overlaps at least a part of the primary discharge port.

6. The foam discharge cap according to claim 3 , wherein
the discharge port is configured to include a first discharge region and a second discharge region, and
the foam discharge cap includes one or both of an inhibiting portion that inhibits the foam discharged from the primary discharge port into the anterior chamber from flowing to the first discharge region and a guiding portion that guides the foam discharged from the primary discharge port into the anterior chamber to the second discharge region.

7. The foam discharge cap according to claim 1 , comprising:
a primary plate-like portion having a primary discharge port that discharges the foam;
an anterior chamber in which the foam discharged from the primary discharge port spreads in an internal space; and
a facing portion that is arranged so as to face the primary discharge port with the anterior chamber interposed between the facing portion and the primary discharge port, and has the discharge port formed in the facing portion, wherein
the facing portion is configured to include a plate-like portion that is arranged so as to face the primary plate-like portion with the anterior chamber interposed between the plate-like portion and the primary plate-like portion and has the discharge port formed in the plate-like portion,
the anterior chamber is a region surrounded by a surrounding wall standing between the primary plate-like portion and the plate-like portion, and
when the foam discharge cap is viewed in the pushing direction, the surrounding wall is accommodated inside the pushing portion, and the discharge port and the primary discharge port are accommodated inside the surrounding wall.

8. The foam discharge cap according to claim 1 , wherein the foam discharged from the discharge port has been formed in a predetermined intended shape.

9. The foam discharge cap according to claim 1 , wherein the discharge port is configured to have a non-circular shape or include plural openings.

10. A foam discharge head that is used while mounted on a cap to be mounted on a container main body storing a liquid agent and discharges foam in response to a pushing operation, the foam discharge head comprising:
a discharge port that is opened in an opposite direction of a pushing direction of the pushing operation and discharges the foam; and
a pushing portion that keeps a distance between a discharge target body receiving the foam and the discharge port constant, wherein
the discharge port is an opening at a tip of a nozzle forming wall standing in the opposite direction,
the pushing portion is an annular standing wall that surrounds a periphery of the discharge port and stands in the opposite direction beyond the discharge port,
the annular standing wall has an opening at a tip thereof in the opposite direction, and
there are no obstacles between the discharge port and the opening of the annular standing wall.

11. The foam discharge head according to claim 10 , wherein
the pushing portion has a standing portion standing at a position which is away from the discharge port in an outward direction, and
the pushing portion has an intercommunicating portion which communicates an inside region and an outside region of the pushing portion with each other.

12. The foam discharge head according to claim 10 , comprising:
a primary discharge port that discharges the foam;
an anterior chamber in which the foam discharged from the primary discharge port spreads in an internal space; and
a facing portion that is arranged so as to face the primary discharge port with the anterior chamber interposed between the facing portion and the primary discharge port and has the discharge port formed in the facing portion.

13. The foam discharge head according to claim 12 , wherein, when the foam discharge head is viewed in the pushing direction, the facing portion covers at least a part of the primary discharge port.

14. The foam discharge head according to claim 12 , wherein
the facing portion is configured to include a protruding portion protruding toward the primary discharge port, and
when the foam discharge head is viewed in the pushing direction, the protruding portion overlaps at least a part of the primary discharge port.

15. The foam discharge head according to claim 12 , wherein
the discharge port is configured to include a first discharge region and a second discharge region, and
the foam discharge head includes one or both of an inhibiting portion that inhibits the foam discharged from the primary discharge port into the anterior chamber from flowing to the first discharge region and a guiding portion that guides the foam discharged from the primary discharge port into the anterior chamber to the second discharge region.

16. The foam discharge head according to claim 10 , comprising:
a primary plate-like portion having a primary discharge port that discharges the foam;
an anterior chamber in which the foam discharged from the primary discharge port spreads in an internal space; and
a facing portion that is arranged so as to face the primary discharge port with the anterior chamber interposed between the facing portion and the primary discharge port, and has the discharge port formed in the facing portion, wherein
the facing portion is configured to include a plate-like portion that is arranged so as to face the primar
