However, as described above, in the structure in which the pull-top type lid is opened by pulling the pull ring, the opening of the spout formed is smaller than the area of the lid. When drunk, the flow rate of various kinds of beverages, which are contents, becomes small, and a sufficiently satisfactory throat feeling cannot be obtained. In particular, in the case of beer, poor passing over the throat was not preferable because it reduced the original taste of beer.

[0004] Further, since the opening area is small, the drinker can hardly see the beverage as the contents from the start to the end of the drink, and simply passes the drink from the mouth to the throat. That is, originally, appetite is also affected by visual factors, but the lack of the visual factors reduces the original taste of the beverage.

[0005] Furthermore, the drinking spout at the top of the can container body is exposed to the outside and is unsanitary. In particular, in the case where the lid is bent inside the can and does not come off from the can, the part which has been exposed to the outside enters the inside of the can, so that any foreign substances or the like adhered to this part Could directly touch the beverage inside and be melted.
Therefore, it was even more unsanitary.

Therefore, the present invention provides a can-opening container having an upper opening which is substantially the same as the opening of a drinking port such as a cup or a mug when the lid is detached. The purpose is to provide

The detaching operation is easier than a cover that can be made.

According to the fourth aspect of the present invention, in addition to the effect of the third aspect of the present invention,
Since the lid can be screwed to the lower end of the can container body, and the lid alone does not scatter alone, recycling is easy and the environment is not adversely affected. In addition, when an undrinked beverage is generated, the lid that is screwed to the lower end of the can container body is screwed again to the upper end, so that the undrinked beverage becomes airtight again, and if for a while Since it can be stored, drinks left over can be used effectively. Further, since there is no need to worry about spilling the contents to the outside, the floor and the like are not stained.

According to the fifth aspect of the present invention, in addition to the effect of the fourth aspect, the canister is fully open.
When the lid is screwed onto the lower end of the can container body, the concave portion of the lid body faces downward of the can container body, and when the entire can container body is placed on an uneven floor surface, etc. Compared to
Since the contact area is small, it is stable without rattling and does not spill the beverage of the contents.

According to a sixth aspect of the present invention, in addition to the effects of the first aspect, the lid and the can main body are formed of a main body. Since the fixing portion and the lid fixing portion that is integral with the main body fixing portion are integrated, the lid can be prevented from loosening due to an external force or the like received during transportation. Further, once the lid is detached from the upper end of the can container main body, the lid fixing portion and the main body fixing portion are divided into two at the dividing cut, and the lid fixing portion is fixed to the lid. Since the part without the fixed surface on the back side is separated from the outer peripheral surface of the lid, it is possible to check at a glance whether there is any evidence of opening in the past and mistakenly beer such as beer mixed with foreign matter I do not drink. Moreover, after the lid is detached from the main body of the can container, the lid fixing portion and the main body fixing portion remain integral with the lid and the main body of the can container, respectively. Like a glass container or the like, a metal piece or the like generated when the lid is detached does not fall to the surroundings, and there is no risk of injury.

According to the seventh aspect of the present invention, in addition to the effect of the sixth embodiment, the upper fully open can is provided.
