Hereinafter, an embodiment (embodiment) for carrying out the present invention will be described in detail with reference to FIG.
As shown in FIG. 1, the present invention relates to an effervescent beverage 1 with a container in which an effervescent beverage 3 is contained in a sealed container 2 with a predetermined content volume.

  As the sealed container 2 for containing the sparkling beverage 3, for example, a can lid having a score and a tab provided adjacent to the score, and a can containing the sparkling beverage 3 by being sealed with the can lid And a can container, a glass bottle, a plastic bottle, and the like. In the case of a can container, those made of aluminum alloy or steel can be suitably used. In addition, the airtight container 2 which can be used by this invention is not limited to these, The effervescent drink 3 of predetermined | prescribed content volume is sealed and accommodated by the empty space ratio and total pressure which are mentioned later. Any shape, material and capacity can be used as long as possible. The sealed container 2 can have a content volume of the sparkling beverage 3 of, for example, 135 mL, 160 mL, 190 mL, 200 mL, 250 mL, 280 mL, 330 mL, 334 mL, 350 mL, 500 mL, 633 mL, 750 mL, 1000 mL, 1500 mL, etc. It is not limited to these, It can select arbitrarily from capacity | capacitances other than having enumerated here.

The sparkling beverage 3 may be any beverage as long as it contains a carbon dioxide gas. Carbon dioxide gas may be dissolved in a beverage by storing carbon dioxide generated by fermentation or the like in a tank, or dissolved in a beverage using a carbonator or the like. Also good.
Moreover, the sparkling beverage 3 may be produced using a plant raw material. Examples of plant raw materials include cereals, beans, and potatoes, and at least one selected from these can be used. Examples of cereals include barley, wheat, rye, rice and corn, and at least one selected from these can be used. Moreover, you may germinate 1 or more types selected from the group which consists of grains, such as barley, wheat, rice, and corn, beans, and potatoes, and / or 1 or more types selected from the said group. The effervescent beverage 3 produced by using barley, wheat germ and the like germinated barley and wheat is called effervescent malt beverage. The sparkling beverage 3 may be an alcoholic beverage containing alcohol or a non-alcoholic beverage not containing alcohol. In the present invention, an alcoholic beverage refers to a beverage having an ethanol content of 1% by volume or more, and a non-alcoholic beverage refers to a beverage having an ethanol content of less than 1% by volume.

  Specific examples of such sparkling beverages 3 include various types of carbon dioxide gas such as beer, sparkling liquor, brewed sake (foaming), liqueur (foaming), spirits (foaming), and cola. Examples include soft drinks, non-alcoholic beer-taste beverages, and non-alcoholic beer cocktails. In addition, beer taste means the peculiar taste and fragrance like beer manufactured by fermentation.

  As for the effervescent drink 1 with a container accommodated in the airtight container 2, it is common that the inside of the airtight container 2 is not filled with the effervescent drink 3. That is, as described above, the sparkling beverage 3 is accommodated in the sealed container 2 with a predetermined content volume, and a part of the sealed container 2 is not filled with the sparkling beverage 3. The space is generally called an empty space, an empty space, a head space, or the like. In the present invention, the capacity of the space is referred to as an empty capacity, and the ratio of the empty capacity to the total capacity of the sealed container 2 is referred to as an empty ratio. The effervescent beverage 1 with a container is filled with nitrogen gas for the purpose of preventing oxidation of the effervescent beverage 3 and preventing deformation of the container. Accordingly, the empty space is a state in which carbon dioxide gas generated from the sparkling beverage 3 and filled nitrogen gas are mixed.

  In the sparkling beverage 1 with a container according to one embodiment of the present invention, the empty space ratio is 8.4% or more, and the total pressure in the sealed container 2 is less than 307 kPa. By simultaneously satisfying the empty space ratio and the total pressure in the closed container 2 under the above conditions, the sparkling beverage 3 and its foam can be made difficult to scatter even when the can is opened after transportation.

When the empty ratio is less than 8.4%, the empty capacity is too small. Therefore, even when the total pressure in the sealed container 2 is less than 307 kPa, the sparkling beverage 3 is opened (for example, when the can is opened). Or the bubbles may scatter.
In addition, when the total pressure in the sealed container 2 is 307 kPa or higher, the total pressure is too high, so even if the empty capacity is 8.4% or more, the sparkling beverage 3 or The bubbles may scatter.

The above empty ratio is preferably 20% or less, more preferably 19% or less, and still more preferably 18% or less. For example, the void ratio is preferably 8.4 to 17.8%, more preferably 11.1 to 16.4%. Moreover, it is also preferable to set it as 13.7%.
The total pressure in the closed container 2 is preferably 100 kPa or more. The total pressure in the sealed container 2 is preferably 107 to 295 kPa, for example.
When the empty space ratio and the total pressure in the sealed container 2 are set in this way, the sparkling beverage 3 and its bubbles can be more reliably prevented from scattering even when the can is opened after transportation.

The carbon dioxide pressure in the sealed container 2 is preferably 90 kPa or higher, specifically 92.1 kPa or higher. If it does in this way, the foaming characteristic of the sparkling beverage 3 can be improved. The foaming characteristics refer to foaming and foam retention when poured into a container such as glass.
Further, the nitrogen gas pressure in the sealed container 2 is preferably 10 kPa or more, specifically 11 kPa or more. If it does in this way, oxidation prevention of the sparkling beverage 3 can be aimed at.
Carbon dioxide filling and nitrogen gas filling can be performed by using a known gas filling machine, respectively.

  Carbon dioxide gas pressure and nitrogen gas pressure in the sealed container 2 are a commercially available dissolved nitrogen / carbon dioxide analyzer equipped with a carbon dioxide gas detector and a nitrogen gas detector including a thermal conductivity detector (TCD) element. Can be measured using. The total pressure in the above-described sealed container 2 is the total value of the carbon dioxide pressure and the nitrogen gas pressure measured using the dissolved nitrogen / carbon dioxide analyzer.

  The sparkling beverage 1 with a container which concerns on one Embodiment demonstrated above makes the empty ratio and the total pressure in the airtight container 2 the specific conditions. Therefore, since the empty ratio is sufficiently secured and the total pressure in the sealed container 2 is not excessively high, even if it is opened (canned) after being transported and subjected to vibration, it is a sparkling beverage. 3 and its bubbles are difficult to scatter. Moreover, since the substance which the sparkling beverage 3 does not originally contain is not added and the raw material is not changed, the flavor of the sparkling beverage 3 is not affected.

  Next, the content of the present invention will be specifically described with reference to an example that exhibits the desired effect of the present invention and a comparative example that does not.

  First, in the sealed container, No. 1 in Table 1. 1 to 14 contains an effervescent malt beverage using 100% malt so as to have an empty volume (mL) and a content volume (mL), that is, beer. Each sample was produced by filling carbon dioxide gas and / or nitrogen gas using a gas filling machine so that the total pressure (kPa) shown in 1 to 14 was obtained.

  As a sealed container, a can lid having a score with a thin wall thickness and a tab provided adjacent to the score, and a can body containing a sparkling beverage by being sealed with the can lid, A can container was used. The total capacity of such a can container is 371 mL.

No. in Table 1 Pre-treatment for fixing the samples shown in 1 to 14 to the elevator 11 of the vibration device 10 shown in FIG. 2 and raising the elevator 11 by 20 cm over about 15 seconds and then dropping it downward 10 times Went.
After each pretreated sample was allowed to stand at 4 ° C. for 3 hours, the sample (can) was placed in the lower right corner of the flat plate 20 with the tab at the 12 o'clock position as shown in FIG. Caused a crack in the score (that is, opened (canned)). Note that the flat plate 20 and the sample shown in FIG. 3 are illustrated in a size different from the actual size for convenience of explanation and illustration. In addition, forged plate was used as the flat plate 20.

  And the maximum scattering distance (cm) and the maximum scattering diameter (mm) of the sparkling beverage and its foam (hereinafter simply referred to as foam) scattered when the can was opened were measured.

  The maximum scattering distance and the maximum scattering diameter shown in Table 1 are No. About 1-3, 6, 10-10, the maximum value in the number of open cans is shown, and About 4, 5, 7-9, the maximum value in 48 cans is shown.

The maximum scattering distance on the flat plate 20 was determined to be acceptable when the maximum scattering distance from the location where the opened opening was located was 200 cm or less, and rejected when the distance exceeded 200 cm.
As for the maximum scattering diameter, those having a diameter of 15 mm or less were accepted, and those exceeding 15 mm were rejected.

Further, the opened No. For each of the cans 1 to 14, the points (points) obtained by multiplying the number of bubbles scattered and the maximum bubble diameter were calculated. That is, no. For points 1 to 3, 6, and 10 to 14, points were calculated for each of the four open cans. For 4, 5, and 7 to 9, points were calculated for each of the 48 cans opened. In calculating the points, those having a maximum diameter of 2 mm or less were not counted.
No. calculated in this way. The average value of the points in each sample was calculated from the points of each sample of 1 to 14 for each can. Table 1 shows the average value of points as points.
As for such points, those having 20 points or less were accepted, and those exceeding 20 points were rejected.

  Table 1 shows the ratio (empty dimension ratio (%)), carbon dioxide gas pressure (kPa), nitrogen gas pressure (kPa) and total pressure of the empty capacity not filled with the sparkling beverage to the total capacity of the can container. The maximum scattering distance (cm), the maximum scattering diameter (mm), and the points described above were shown together with (kPa). The underline in Table 1 indicates that the requirements of the present invention are not satisfied.

Carbon dioxide gas pressure and nitrogen gas pressure of the sample were measured using a dissolved nitrogen / carbon dioxide analyzer (Hakku Co., Ltd.) equipped with a carbon dioxide gas detector including a thermal conductivity detector (TCD) element and a nitrogen gas detector. Measurement was performed using an Ultra model 511 series.
Specifically, by inserting the needle-shaped sampling unit connected to the carbon dioxide detector and nitrogen gas detector of the analyzer into the empty space in the sample (inside the can) adjusted to 20 ° C., The carbon dioxide pressure and nitrogen gas pressure within the empty space were measured. The measurement range of the carbon dioxide gas detector was 0 to 10 bar, and the measurement range of the nitrogen gas detector was 0 to 350 ppm.
Table 1 shows the measured value (bar) by the carbon dioxide gas detector and the measured value (ppm) by the nitrogen gas detector converted to Pascal (Pa) which is an SI assembly unit of pressure.

As shown in Table 1, no. Since 1-9 and 11 had the empty space ratio and the total pressure in the sealed container satisfied the requirements of the present invention, all the evaluation results of the maximum scattering distance, the maximum scattering diameter, and the points were acceptable.
In contrast, no. Since 10, 12 to 14 did not satisfy the requirements of the present invention in the empty space ratio and the sealed container, the evaluation result of any of the maximum scattering distance, the maximum scattering diameter, and the point was rejected.

  Specifically, no. In Nos. 10 and 12, the total pressure in the sealed container was too high. No. 13 has a blank size ratio too low. For No. 14, the empty dimension ratio was too low, and the total pressure in the sealed container was too high, so that the maximum scattering distance, the maximum scattering diameter, and the points were all rejected.
