"Example"
Next, examples of the sparkling beverage container of the present embodiment having the above-described configuration will be described. In addition, in FIG. 6, the table | surface which showed the longitudinal cross-sectional view of the container for sparkling beverages by the comparative example 1 and the various values of the said container for sparkling beverages is shown, and in FIG. 7, the container for sparkling beverages by the comparative example 2 is shown. The longitudinal cross-sectional view and the table | surface which showed the various values of the said sparkling beverage container are shown. Moreover, in FIG. 1, the table | surface which showed the longitudinal cross-sectional view of the container for sparkling beverages by the Example of this invention and the various values of the said container for sparkling beverages is shown. In addition, the height and capacity | capacitance of each container for sparkling beverages of Comparative Example 1, Comparative Example 2 and Example 1 are as shown in Table 1 below (with regard to the height, FIG. 6, FIG. Also shown in each of FIG.
In addition, although the height and capacity | capacitance in the comparative example 1 and the comparative example 2 are actual measurement values, the height and capacity | capacitance in an Example are nominal values.

  The table of FIG. 1, FIG. 6 and FIG. 7 shows the distance from the center line to the outer surface of the outer diameter and the cross section relative to the height position of each sparkling beverage container, and the height direction position. The thickness and the distance from the center line to the inner surface in the cross section are shown.

  The applicant of the present invention evaluated the size of the foam regeneration function of each of the sparkling beverage containers of Comparative Example 1, Comparative Example 2, and Example 1 by the foam height and the foam retention size. Note that the foam regeneration function is a general drinking method of effervescent beverages such as beer in the poured container, and when the remaining amount of effervescent beverages is low, the effervescent beverage It is the function which enlarges the bubble height in a container by reproducing | regenerating the bubble derived from.

The bubble height and bubble retention were determined by the following formulas.
Bubble height (mm) = Bubble surface height (mm)-Liquid surface height (mm) ... (Formula 1)
Foam retention (%) = (foam height after 4 minutes (or 6 minutes) after pouring / foam height after 2 minutes (or 4 minutes) after pouring) x 100 (Formula 2)
In FIG. 2, “A” indicates the bubble surface height, and “B” indicates the liquid surface height.

  In addition, it was decided that the beer would be discarded 1 minute after the pouring, assuming that the foam is not stable immediately after the pouring and that it is used for drinking within 30 seconds to 1 minute after the pouring. Also, in order to measure quickly, the measurement condition 1 to be described later obtains the foam height and the bubble retention (%) after 2 minutes and 4 minutes after the extraction, and the measurement condition 2 to be described later requires 4 minutes to dispense. The bubble height and bubble retention (%) were determined after and 6 minutes after dispensing.

  By the way, in the evaluation experiment, one instant cooling dispenser (Hoshizaki DBF-K40A2) and one barrel of 20 g of giraffe squeezed <raw> were prepared in a test room at 25 ° C., and the test was started 48 hours later.

  First, for the effervescent beverage containers of Example, Comparative Example 1 and Comparative Example 2 to be evaluated, the liquid was poured out to 70% of the height of the effervescent beverage container as usual, and then the effervescent beverage container Foamed to the mouth.

  And the foam height and foam retention of the beer in the container for sparkling beverages were measured under the following two conditions.

<< Measurement condition 1 >>
First, the measurement condition 1 will be described.

  As shown in FIG. 3, beer was discarded until the remaining liquid amount became about 50% after 1 minute of pouring. The reason for discarding beer in this way is that beer has been drunk and decreased. The effervescent beverage container was tilted, and the amount of the remaining liquid was determined to be about 50% when the foam liquid boundary line reached the circumference of the lower end of the effervescent beverage container.

  Two minutes after dispensing, the foam surface height and the liquid surface height were measured. Moreover, the foam surface height and the liquid surface height were also measured 4 minutes after the pouring.

  The foam height and foam retention were determined from the measured foam surface height and liquid level height and the above-described formulas (1) and (2).

<< Measurement condition 2 >>
Next, measurement condition 2 will be described.

  As shown in FIG. 3, beer was discarded until the remaining liquid amount became about 50% after 1 minute of pouring. The reason why the beer was discarded 1 minute after pouring is because the foam height is not stable immediately after erecting the effervescent beverage container as described above.

  Next, as shown in FIG. 4, beer was discarded until the remaining liquid amount became about 25% 3 minutes after the pouring. In addition, draw a line (center line) that bisects the bottom of the effervescent beverage container in advance, tilt the effervescent beverage container, and when the foam liquid boundary reaches the center line, the remaining liquid amount is about 25%. It was.

  The foam surface height and the liquid surface height were measured 4 minutes after dispensing. Moreover, the foam surface height and the liquid surface height were also measured 6 minutes after the pouring.

  The foam height and foam retention were determined from the measured foam surface height and liquid level height and the above-described formulas (1) and (2).

<< Measurement results under measurement condition 1 >>
Table 2 below shows the foam height and foam retention data measured under measurement condition 1.

  Thus, according to the present Example, when the average value of Comparative Example 1 and Comparative Example 2 is set to 100, the bubble height after 2 minutes (1 minute after disposal) is + 36.3%, A difference of + 69.0% in the foam height 4 minutes after the dispensing (3 minutes after disposal) was observed.

  Moreover, according to the present Example, when the average value of the comparative example 1 and the comparative example 2 was set to 100, the foam retention until 4 minutes after extraction showed the advantage of + 24.2%.

<< Measurement results under measurement condition 2 >>
Table 3 below shows the foam height and foam retention data measured under measurement condition 2.

  Thus, according to the present Example, when the average value of Comparative Example 1 and Comparative Example 2 is set to 100, the bubble height becomes + 64.1% after 4 minutes of pouring (after 1 minute of second disposal). A difference of foam height of + 84.0% was recognized 6 minutes after the pouring (3 minutes after the second disposal).

  Moreover, according to the present Example, when the average value of the comparative example 1 and the comparative example 2 was set to 100, the foam retention until 6 minutes after extraction showed the predominance of + 12.0%.

  5A shows a graph of the average value of the data shown in Table 2, and FIG. 5B shows a graph of the average value of the data shown in Table 3.

《Significant difference measurement result》
Table 4 below shows the result of the mean difference test (t-test).

  As shown in Table 4, the effervescent beverage container of this example has a significant difference in the foam regeneration function (both the foam height and the foam retention) compared to the effervescent beverage containers of Comparative Examples 1 and 2. In particular, a significant difference in the height of the foam is remarkable. In addition, the difference in the foam regeneration function is greater when the remaining amount of beer is reduced.

  From the above, according to the sparkling beverage container of the present example, it is understood that the foam can be held up to the last bite, the liquid level of beer can be prevented from touching the air, and a beautiful appearance can be maintained. .

  By the way, the foam regeneration function of the effervescent beverage container of this example is excellent when the effervescent beverage container is upright with the beer remaining in the effervescent beverage container. This is because bubbles are regenerated by the occurrence of convection.
