Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a foamed beverage can such as beer having a foaming function.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, for example, a beer can has been formed of a pull-top type cylindrical metal can. When drinking, push or pull the pull tab to push the tongue-shaped opening piece into the top plate, which is the can lid, or cut off from the top plate, and when the opening is made, put the upper edge of the beer can in the mouth He drinks beer cans while tilting it.
[0003]
[Problems to be solved by the invention]
When the opening of the beer can is opened, air enters through this opening and bubbles are generated, causing a problem of impairing the taste of the beer, but on the other hand, the temperature at which this foam acts as a lid and affects the taste It has the effect of suppressing the rise and release of bubbles, and it is also true that the drinker has the effect of giving a good image such as a refreshing feeling.
According to the conventional example, it is difficult to generate a new effective foam after opening, and there is a problem that beer foam overflows from the beer can immediately after opening.
It is an object of the present invention to easily generate new foam after opening, and to suppress the inconvenience that beverage foam overflows from a beverage can immediately after opening.
[0004]
[Means for Solving the Problems]
A first feature of the present invention is that a can body, a foaming operation section provided on one or both of a bottom and a body of the can body, and a recess for a drinking spout formed on an upper portion of the can body. And an opening lid provided on the bottom surface of the concave portion and having a tab. The foaming operation section can apply a pressing force for generating foam to a sparkling beverage such as beer in the can body. The recess has a space in which a bubble reservoir for temporarily preventing foam from overflowing out of the can body is provided. The opening lid is surrounded by an opening score formed along the inner wall of the recess.
A second feature of the present invention is that it has the first feature and is provided on the bottom surface of the bottom of the can body.
A third aspect of the present invention is provided with the first or second aspect, wherein the foaming operation section has a spring property and is elastically deformable inside the can body by a pressing force.
According to a fourth aspect of the present invention, there is provided the above-described first or second aspect, wherein the foaming operation section has a spring property, and the bottom surface of the can body is provided in a space of a base formed at the bottom of the can body. It is formed so as to protrude outward and is capable of being elastically deformed inside the can main body by a pressing force.
According to a fifth aspect of the present invention, there is provided the above-described first, second, third, or fourth aspect, wherein the opening lid is formed along and near the inner wall of the recess. Being surrounded by scores.
[0005]
[Action]
In the state where the opening lid is opened, the foaming beverage in the can main body is pressed by the operation of the foaming operation unit, and foam is generated and accumulated in the recess.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
The beer can, which is a sparkling beverage can shown in FIGS. 1 to 5, includes a can body 1, a frothing operation unit 2 provided at the bottom of the can body, and a recess for a drinking spout formed at the top of the can body. 3 and an opening lid 4 provided on the bottom surface of the bottom of the concave portion.
The can body 1 is made of metal, for example, aluminum, and has a base 5 at the bottom and a space 7 between the bottom 6.
The foaming operation section 2 is formed so as to protrude from the can body bottom surface 6 into the space 7 and has a spring property, and can be elastically deformed to the inside of the can body by the pressing force. The foaming operation unit 2 is normally maintained in a state of being protruded outwardly from the bottom surface 6 as shown by the solid line in FIG. 1, and is temporarily convexed inward by being pushed upward in FIG. 1. After being elastically deformed, it is restored to its original state. The foaming operation unit 2 applies a pressing force to the beer 8 (FIG. 6) in the can main body 1 with the operation in which the bulging shape is elastically deformed from the outside to the inside and then restored to the original state.
The spout recess 3 has a volume capable of storing bubbles in its internal space, and has a function of temporarily preventing foam from overflowing the outside of the can body.
The opening lid 4 is provided on the bottom bottom surface 9 of the recess 3 and has a circular shape surrounded by an opening score 10 formed along the inner wall 3a. In the illustrated example, the opening cover 10 occupies almost the entire bottom surface 9 because the opening score 10 is close to the inner wall 3 a of the recess 3. A tab 12 is connected to the upper surface of the opening lid 4 via a rivet 11. By pulling the tab 12 upward, the opening lid 4 is disengaged from the bottom surface 9 of the concave portion 3 along the opening score 10, and a through hole is formed as the opening 1a (FIG. 6).
[0007]
Next, the method of use will be described.
In the can body 1 shown in FIG. 1, by pulling the tab 12 upward, the opening lid 4 comes off the bottom surface 9 of the concave portion 3, and as a result, an opening portion 1a as a through hole is formed on the bottom surface as shown in FIG. Then, air enters the can body 1 from the opening 1a, and bubbles 8a are generated, and accumulate in the recess 3 through the opening. Thereafter, the can body 1 is tilted, and the beer 8 in the can body is drunk using the recess 3 for the drinking mouth as a drinking mouth.
After the can body 1 is opened, it does not foam, but when foaming is desired, when the foaming operation part 2 is pressed about two or three times, the elastic deformation and restoring force due to the spring property cause the foaming operation in the direction of the arrow shown in FIG. In order to move the lower part of the beer of the can body 1 up and down along with the up and down movement, the foam 8a is generated, and the foam again collects in the recess 3 through the opening 1a.
As a result, the drinker gives a fresh impression that new beer is poured into the can body 1.
[0008]
The material of the can body 1 is not limited to metal such as aluminum, but may be plastic or paper. The sparkling beverage 8 is not limited to beer. In the whipping operation section 2, when the spring property cannot be ensured depending on the material of the can body 1, an operation knob may be provided, and the operation knob may be operated to apply pressure to the beer 8 to exert the whipping function. . Of course, the operation is not limited to the material, and an operation knob may be provided in the foaming operation unit 2. The number of foaming operation units may be two or more, and is not limited to one, and may be provided on the body of the can body. Depending on the size of the can body 1, it can be used as a multi-purpose storage section, such as putting a beverage knob or a premium in the recess 3 in advance.
[0009]
【The invention's effect】
According to the present invention, since the foaming operation section is provided, it is possible to easily generate foam at any time after opening, to give a good image to a drinker, and to provide a recess for a drinking mouth. As a result, it is possible to prevent the bubbles from suddenly overflowing from the can body at the time of opening.
