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 container that discharges foam in response to a pushing operation, the foam discharge container 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 container 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 the standing portion, and an intercommunicating portion which communicates an inside region and an outside region of the pushing portion with each other.

3. The foam discharge container according to claim 2 , 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 container 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.

4. The foam discharge container 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.

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

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

7. The foam discharge container according to claim 4 , wherein
the discharge port is configured to include a first discharge region and a second discharge region, and
the foam discharge container 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.

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

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

10. The foam discharge container according to claim 1 , comprising:
a container main body that stores a liquid agent; and
a foam discharge cap that is mounted on the container main body and discharges the foam in response to the pushing operation, wherein
the foam discharge cap includes the discharge port and the pushing portion, and further includes a pump portion that makes the foam from the liquid agent upon movement of the container main body relative to the pushing portion in the opposite direction and discharges the foam from the discharge port, and
the container main body is an operating portion which is grasped and pushed by a user in the pushing operation.

11. The foam discharge container according to claim 10 , wherein the foam discharge container is capable of self-standing in a state where the pushing portion is in contact with a placement surface with the discharge port facing in a downward direction.

12. The foam discharge container according to claim 10 , wherein
the container main body has a neck portion, the foam discharge cap has a tubular mounting portion that is mounted on the neck portion while surrounding the neck portion, and a tubular portion that extends from the pushing portion to the container main body and covers a periphery of the mounting portion or the container main body, and
an internal space of the pushing portion intercommunicates with an external space of the foam discharge container via an internal space of the tubular portion and a gap between an inner peripheral surface of the tubular portion and an outer peripheral surface of the mounting portion or the container main body.

13. The foam discharge container according to claim 1 , wherein the foam discharge container is an upright and inverted foam discharge container that has a container main body storing a liquid agent and is usable in both of an upright state where the discharge port is placed to face in an upward direction and an inverted state where the discharge port is placed to face in a downward direction.

14. A liquid agent discharge container that discharges a liquid agent in response to a pushing operation, the liquid agent discharge container comprising:
a container main body that stores a liquid agent; and
a liquid agent discharge cap that is mounted on the container main body, and discharges the liquid agent in response to the pushing operation, wherein
the liquid agent discharge cap includes
a discharge port which is opened in a direction opposite of a pushing direction of the pushing operation and discharges the liquid agent,
a pushing portion that keeps a distance between a discharge target body receiving the liquid agent and the discharge port constant, and
a pump portion that discharges the liquid agent from the discharge port upon movement of the container main body relative to the pushing portion in the opposite direction,

the container main body is an operating portion to be grasped and pushed by a user in the pushing operation,
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 discharg
