Abstract

An object of the present invention is to facilitate discharge of the content in a dispensing container having a delamination structure so as to minimize the amount of remaining content. In order to achieve this object, a gas is housed in the internal container 11 to thereby form a gas space S therein and the volume of the gas is 4% or more of the volume of the internal container 11 . The gas preferably moves rapidly in the internal container 11 when the dispensing container is tilted to a discharge posture in order to discharge the content M from the discharge port 14 . The gas may be encapsulated in a gas bag or the gas may be encapsulated in a gas chamber formed in the internal container 11.

First claim

What is claimed is:

1. A dispensing container, comprising:
a content which is a soy sauce-containing flavoring material;

a container body having a flexible internal container which contains the 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 in a delaminatable manner to the external container, where the external container is elastically-deformable and has a suction port which sucks external air in between the internal container and the external container;
a discharge cap attached to a spout of the container body, where a discharge port to discharge the content is disposed on a top part of the discharge cap, an external-air inlet port to communicate the external air from outside of the dispensing container to the suction port is disposed on the top part of the discharge cap, and an over-cap is connected via a hinge to cover the discharge port and the external-air inlet port;
an air valve disposed between the external-air inlet port and the suction port and switches between a communicated state and a shutoff state of communication between the external-air inlet port and the suction port; and
a gas which is more easily compressed as compared to the content housed in the internal container, the gas having a low reactivity with the content, where a volume of the gas is 4% or more of a volume of the internal container,
wherein the gas moves in the internal container when the dispensing containers is tilted to a discharge posture in order to discharge the content from the discharge port.

2. The dispensing container according to claim 1 , wherein the gas is encapsulated in a gas bag.

3. The dispensing container according to claim 2 , wherein the soy sauce-containing flavoring material is a liquid.

4. The dispensing container according to claim 1 , wherein the gas is encapsulated in a gas chamber formed in the internal container.

5. The dispensing container according to claim 4 , wherein the soy sauce-containing flavoring material is a liquid.

6. The dispensing container according to claim 4 , wherein the gas chamber is disposed at a bottom on an inside of the internal container.

7. The dispensing container according to claim 6 , wherein the soy sauce-containing flavoring material is a liquid.

8. The dispensing container according to claim 1 , wherein the sauce-containing flavoring material is a liquid.

9. A dispensing container, comprising:
a container body having a deformable, flexible internal container and an elastically-deformable external container, where the internal container is attached in a delaminatable manner to the external container, and the external container has a suction port which sucks external air in between the internal container and the external container;
a discharge cap attached to a spout of the container body, where a discharge port to discharge the content is disposed on a top part of the discharge cap and an external-air inlet port to communicate the external air from outside of the dispensing container to the suction port is disposed on the top part of the discharge cap;
an air valve disposed between the external-air inlet port and the suction port to switch between a communicated state and a shutoff state of communication of the external air between the external-air inlet port and the suction port; and
a gas housed in the internal container, wherein the gas occupies 4% or more of a volume of the internal container.

10. The dispensing container according to claim 9 , further comprising:
a liquid content housed in the internal container that occupies a remainder of the volume of the internal container.

11. The dispensing container according to claim 10 , wherein the liquid content is a soy sauce-containing liquid.

12. The dispensing container according to claim 10 , wherein the gas is more easily compressed as compared to the liquid content.

13. The dispensing container according to claim 10 , wherein the gas has a low reactivity with the liquid content.

14. The dispensing container according to claim 9 , further comprising:
an over-cap connected via a hinge to cover the discharge port and the external-air inlet port.

15. The dispensing container according to claim 9 , wherein the gas occupies 4% or more of a volume of the internal container in a non-delaminated state.

16. A dispensing container, comprising:
a liquid content;
a container body having a deformable, flexible internal container and an elastically-deformable external container, where the internal container is attached in a delaminatable manner to the external container to contain the liquid content and deflates according to a volume of the liquid content, and the external container has a suction port which sucks external air in between the internal container and the external container;
a discharge cap attached to a spout of the container body, where a discharge port to discharge the content is disposed on a top part of the discharge cap and an external-air inlet port to communicate the external air from outside of the dispensing container to the suction port is disposed on the top part of the discharge cap;
an air valve disposed between the external-air inlet port and the suction port to switch between a communicated state and a shutoff state of communication of the external air between the external-air inlet port and the suction port; and
a gas container that encapsulates a gas, where the gas container is housed in the internal container, and the gas container occupies 4% or more of a volume of the internal container.

17. The dispensing container according to claim 16 , wherein the gas container is disposed at a bottom of the internal container.
