Abstract

A dispensing container provides that after discharging content, the content which has not been returned to an internal container is prevented from leaking out of a discharge port. The dispensing container has an internal container which contains content and an external container in which the internal container is attached. The external container is provided with a suction port for sucking external air in between the internal container and the external container. A discharge cap is attached to a spout and is provided with a discharge port for discharging the content. The discharge cap includes an inside plug which closes the spout and a cylindrical body covering the inside plug and being provided with the discharge port. The inside plug is provided with a communication port. A valve that is slidable along an axial direction of the communication port is provided to open and close the communication port.

First claim

What is claimed is:

1. A dispensing container comprising:
a container body having a flexible internal container to contain content and deforms so as to deflate with a decreasing amount of the content and an external container in which the internal container is attached, the external container being provided with a suction port for sucking external air in between the internal container and the external container;
a discharge cap which is attached to a spout of the container body and provided with a discharge port for discharging the content;
an external-air inlet port which communicates between outside and the suction port; and
an air valve which switches between a communicated state and a shutoff state of communication between the external-air inlet port and the suction port, wherein:
the discharge cap includes: an inside plug member which closes the spout;
and a cylindrical body member having a top-closed cylindrical shape, the cylindrical body member covering the inside plug member and being provided with the discharge port;
the inside plug member is provided with a communication port which communicates between the discharge port and the internal container; and
a valve body is arranged and fitted in the communication port so as to be slidable along an axial direction of the communication port, the valve body being elastically displaced along the axial direction so as to open and close the communication port.

2. The dispensing container according to claim 1 , wherein the inside plug member includes:
a plug body having an outer circumferential end arranged on an opening end of the spout, the plug body having a through hole which extends therethrough and opens to an interior of the internal container; and
a cylindrical communicating part which is provided upright on the plug body and in which the through hole opens, and where an interior of the cylindrical communicating part defines the communication port,
wherein the through hole has a diameter smaller than that of the communication port.

3. The dispensing container according to claim 2 , wherein the valve body is connected via a plurality of deformable elastic connecting pieces to a cylindrical member which is arranged coaxially with the cylindrical communicating part.

4. The dispensing container according to claim 3 , wherein the plurality of elastic connecting pieces are arranged circumferentially at regular intervals about the axial direction of the communication port.

5. The dispensing container according to claim 4 , wherein the plurality of elastic connecting pieces are each circumferentially curved.

6. The dispensing container according to claim 1 , wherein the cylindrical body member is provided with a displacement amount restrictor which abuts onto the valve body slidable along the axial direction to restrict an amount of elastic displacement of the valve body.

7. The dispensing container according to claim 1 , further comprising:
an over-cap removably attached to the discharge cap,
wherein the over-cap is provided with a seal part which is removably fitted into the discharge port.

8. The dispensing container according to claim 7 , wherein the seal part suppresses the elastic displacement of the valve body in a covered state with the over-cap being closed.

9. The dispensing container according to claim 1 , wherein a flow-allowing groove which allows the content to flow therethrough is formed in a portion of a valve seat of the valve body, the portion being in contact with the valve body.
