BACKGROUND ART A portable beverage container having an integral external shape and provided with two kinds of independent containers inside is conventionally known (for example, Japanese Utility Model Laid-Open No. 63-167927).

The above-mentioned known beverage container is one in which the bottoms of two inner containers are abutted against each other, and the opening portions are oriented in the opposite direction, and the beverage container is assembled into the container body.

[Problems to be solved by the device]

In summer and the like, there is a demand not only to carry two types of beverages but also to carry them as cold beverages by freezing them.

However, in the above-mentioned beverage container, since the inner container cannot be separated from the body, it is generally impossible to freeze the inner beverage in a freezer or the like. In addition, since the beverages in the inner containers are spatially separated from each other, they cannot exchange heat with each other.

Therefore, this invention can store two kinds of beverages simultaneously and independently, can appropriately separate the outer container and the inner container, and can exchange heat between the two kinds of beverages. An object is to provide a double container for beverages.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention relates to a double container for beverage comprising a combination of an outer container and an inner container, wherein an outer container is provided with openings at both ends and one end is provided with an opening. The opening of the inner container, which is inserted into and out of the opening of one of the containers so as to be freely inserted into and removed from the container, and is engaged with the one opening of the outer container while maintaining watertightness, It is configured such that it is openably and closably closed by a plug engaged with, and the other opening of the outer container is openably and closably closed by another plug.

[Action]

The inner container is removed from the outer container and the desired beverage is placed in the inner container, and it is frozen or inserted into the outer container without freezing. When the beverage is not frozen, the desired beverage may be placed in the inner container inserted into the outer container. Then, the opening of the inner container is placed on the opening of the outer container, and the opening of the inner container is closed by engaging the stopper with the opening of the outer container. Next, it is turned upside down and another desired beverage is put into the other opening of the outer container and closed by another stopper.

Since the beverage contained in the outer container surrounds the beverage contained in the inner container, heat exchange is performed between both beverages over time.
