BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can product and, more particularly, to a liquid storage can having a double opening.

[0002]

2. Description of the Related Art In recent years, with the spread of vending machines, consumption of can products has been expanding. In addition, with the diversification of personal preferences, can products are often added as additives to produce different products, and a wide variety of products are sold. For example, if it is a canned coffee, even if it is the same brand of coffee, it was manufactured and sold by changing the packaging as a different product for each type, such as black, sweetened, with milk, with sugar and milk. Further, even in the case of alcoholic beverages, for example, the same shochu may be sold after adding juices such as lemon and plum. On the other hand, lids for cans and the like have conventionally been opened using a can opener, but recently many with a pull tab have been sold. By lifting the pull tab, the can was easily opened.

[0003]

However, although many kinds of the conventional can products are manufactured, one can can only taste one kind of taste. For this reason, even if a person may get bored while drinking a can product, the taste cannot be changed on the way. On the other hand, in a can product having a wide mouth such as a canned product, when the can is opened in an inclined state, the liquid inside may be spilled. The present invention has been made in view of such circumstances, and it is possible to easily change the taste by adding an additive to a can product, and to change the size of the opening of the can to discharge the content. It is an object of the present invention to provide a liquid storage can that can adjust the pressure.
