Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage container capable of cooling a child container.

[0002]

2. Description of the Related Art As a container for storing beer, a barrel container for storing a large amount of beer and 250 ml to 2 ml of beer.
Can containers that are stored in the liter range are known. Beer is generally said to be delicious when drinked in a cold state, so canned beer (called canned beer) is cooled in the refrigerator until just before eating or drinking, or kept warm by cooling it from a barrel or can container in the refrigerator. I was pouring beer into a beer jockey and eating and drinking beer in a cold state.
(For example, JP-A-57-68396, JP-A-4-18297, JP-A-3-56256)

[0003]

Among the cans having a capacity of 1 to 2 liters, the cans are cooled in a refrigerator, and beer is poured into the jockey from the cooled cans for drinking. In this case, hold the cooled can container in the open air, and drink the beer from the cooled can container while pouring it into a jockey or a cup, i.e., it is less likely to drink the whole amount at a time, so with the passage of time. There was a problem that the cooling effect of the can container was faint and the taste of beer was reduced.

In addition, even in the heat-retaining beer jockey,
Before using the jockey, it is cooled in a refrigerator and beer is poured into the jockey, so it is effective for 1-2 times use, but there is a problem that the cooling power decreases with the passage of time. It was Therefore, the present invention has been made in view of such problems of the prior art, and its purpose is to provide a beverage container capable of keeping a beverage liquid such as beer in a cooled state for a long time. To provide.

[0005]

In order to achieve the above object, a beverage container of the present invention is a double container having a child container inside a parent container, and a lower opening part communicating with the inside of the bottom part of the parent container. Is provided, the engaging portion is provided on the inner periphery of the lower opening portion, the engaging portion for engaging with the engaging portion of the lower opening portion is provided on the outer periphery of the bottom lid, or the engaging portion is provided on the inner side of the bottom lid, The sub-container is provided with an engaging part that engages with the engaging part of the bottom lid, so that the bottom opening can be closed by fitting and detaching the bottom lid, and a cool substance is stored inside the parent container. As a substance, a cold insulator or an ice piece in which a gel-like substance which solidifies at a cold temperature and softens at a normal temperature is enclosed in a bag is used.

[0006]

Since the lower opening portion is provided at the bottom of the parent container and the lower opening portion can be closed by the removable bottom lid, the cold insulating material is put inside the parent container by fitting and removing the bottom lid. And the child container can be kept cold by the cold keeping substance.

In the barrel-shaped parent container 1 which is divided into upper and lower parts, even if the ice pieces 9b of the cold insulating substance 9 are thawed, they do not leak.

Since the beverage container according to the present invention has the above structure, the cold insulator 9a of the cold insulating substance 9 is put in a refrigerator and solidified in advance, and first, the bottom lid 5 is detached from the lower opening 3 of the parent container 1,
The cold insulator 9a is put into the parent container 1 through the lower opening 3 and fitted into the stepped bottom portion 6b of the child container 6 or the recess 6d of the child container bottom wall 6c, or in the storage chamber 8 of the bottom lid 5. After the storage, if the bottom lid 5 is fitted and closed in the lower mouth portion 3, the cold insulator 9a put inside the parent container 1 touches the bottom wall 6c of the child container 6 or the bottom portion 6b.
The child container 6 is cooled by the cold insulator 9a, and the beverage liquid such as beer contained in the child container 6 is kept cold.

When the cold insulator 9a contained in the beverage container of the present invention is softened, the bottom lid 5 is detached from the lower mouth portion 3, the cold insulator 9a is taken out from the opened lower mouth portion 3 and put in the refrigerator again. Solidify and use repeatedly. Replenishment of the beverage liquid to the child container 6 may be performed before or after containing the cold insulating substance 9. When the beverage container of the present invention is used to store beer, the parent container 1 is placed sideways and the cock C attached to the upper lid 15 is supported downward, and the beer is poured from the cock C into a jockey or a cup.

The beverage container according to the present invention is not limited to the above embodiment. For example, as a means for attaching / detaching the parent container 1 and the bottom lid 5, the engaging portion 7 is formed on the female screw 7c and the engaging portion is formed. The same object can be achieved by forming 4, 16 on the male screw 4c that is screwed into the female screw 7c. If the upper lid 15 is made of a transparent synthetic resin or the bottom lid 5 and the child container 6 are made of a transparent synthetic resin, the remaining amount in the child container 6 can be seen through. Further, the shape and structure of the parent container 1 and the bottom lid 5, the child container 6, and the cold insulator 9a, the fitting means of the parent container 1 and the bottom lid 5 and the like can be appropriately changed without departing from the gist of the present invention.

[0022]

Since the beverage container according to the present invention has the above-mentioned structure, it has the following effects. Since the lower opening is provided at the bottom of the parent container and the lower opening can be closed with the bottom lid, the cold insulator of the cold insulating substance is put inside the parent container by attaching or detaching the bottom lid, or Since the ice pieces are put between the parent container and the child container, the child container can be kept cold for a long time by the cold insulator or the ice pieces of the cold insulating material. As a result, the beverage liquid such as beer contained in the child container can be drunk for a long time and deliciously.

Even if the cold insulator of the cold insulator contained in the parent container is softened, if the softened cold insulator is taken out from the inside of the parent container and put in the freezer for several hours, it will be cooled and solidified again. Not only can it be used repeatedly until the cold insulator is damaged, but ice pieces to be inserted between the parent container and the child container can also be easily made in a general household refrigerator or a commercial refrigerator, so the beverage container of the present invention can be provided at low cost. You can Further, since the cold insulator can be inserted into or removed from or the ice pieces can be put in by simply attaching or detaching the bottom lid, the handling thereof is also simple.
