There was an improvement in quality and flavor such as deterioration.

Further, in the conventional liquid emulsion product 10, because of the shape of the container, it is difficult to open the container when opening the container for the first time, and when it is desired to pour a small amount into coffee or the like, it is difficult to control the dispensing amount, There were structural improvements, such as the possibility of large amounts being poured out from. In addition, after pouring out the liquid emulsion from the container, the liquid emulsion is apt to adhere to the spout 12 of the container, and when the container is stored for a long time, the liquid emulsification is solidified at the spout 12. There were also improvements such as binding and discoloration of the spout 12.

Furthermore, in the conventional gable-top type paper container 11, the spout 12 cannot be completely sealed, so if the contents are accidentally dropped after being opened, the contents will come out of the spout 12 There is a restriction that it easily leaks out, and that when it is stored in a refrigerator or the like after it has been opened, it must be placed with the spout 12 facing upward, and it cannot be placed on its side.

On the other hand, in the conventional liquid emulsion product in which a small amount of cup-shaped plastic container is filled with liquid emulsion, when you want to pour only a small amount into coffee etc., it is used once (1 to 2 in the container) It is convenient and suitable, but its use and dose are limited, and if you want to inject a large amount at home or in a cafeteria, etc., it should be less than the appropriate amount in one use (1 to 2 in a container). Therefore, there is a structural improvement in that the container has to be opened many times (a plurality of containers), and the operation becomes complicated due to the opening.

In addition to the container as described above, for example, in Patent Document 1, the contents of the container have high sealing property and storability, and at the time of opening, they can be safely opened and poured without damaging a finger or the like. It describes a container with a spout that can be dispensed. Further, Patent Document 2 describes a self-supporting container having good heat-adhesiveness and light-shielding property while having high designability due to high self-supporting property. Furthermore, Patent Document 3 describes a container that can easily and surely refill a liquid product into another container. Then, Patent Document 4 describes a spout plug provided with a spout having excellent liquid drainage property. Further, Patent Document 5 describes a container capable of limiting the flow rate in the liquid pouring out.
