I checked the performance of “Vacuum Insulated Carbonated Bottle” that allows you to carry carbonated drinks cold-GIGAZINE

Since carbonated drinks cannot be put in a general cold storage bottle, it is necessary to use a cooler box that is inconvenient to carry in order to keep cola and beer cold. Meanwhile, a cold storage bottle compatible with carbonated drinks from Tiger Thermos “Vacuum insulated carbonated bottleAppeared on January 21, 2022 (Friday). The vacuum-insulated carbonated bottle is equipped with a gas vent valve to keep carbonated drinks safe, and the inner surface is specially processed to prevent carbonic acid from coming out, so actually keep the cola cool. I checked the performance.

◆ Checking the appearance of vacuum-insulated carbonated bottles
The package of the vacuum insulated carbonated bottle looks like this.

Inside the package was a vacuum-insulated carbonated bottle body and explanatory documents.

There are four sizes of vacuum-insulated carbonated bottles, 0.5L, 0.8L, 1.2L, and 1.5L, and each has a lineup of three colors: copper (copper), emerald, and steel. This time, I will use 0.5L emerald.

The surface of the bottle is processed to have a rough texture, making it non-slip.

The cap has two protrusions to assist in opening.

Also, the cap and bottle are connected by a strap, so you don’t have to worry about dropping the cap.

A QR code is printed on the bottom to access the online manual.

Since a safety valve is installed inside the stopper, the internal pressure does not rise too much even if you put a carbonated drink, and you can keep it cool safely.

The actual weight of the vacuum-insulated carbonated bottle was 274g.

◆ I actually tried to keep the cola cold
In order to check the cold insulation performance and carbonic acid retention capacity of the vacuum insulated carbonic acid bottle, I will actually cool the cola.

First, gently pour the cola chilled in the refrigerator into the bottle. This time, the 0.5L version of the vacuum-insulated carbonated bottle contained all the cola in a 500ml PET bottle, and the lid was closed without any problems.

I also prepared another cola and left it in a room at room temperature of 26 degrees for 5 hours with a vacuum-insulated carbonated bottle.

The following movie is a picture of pouring cola into a cup under the conditions of “immediately after taking it out of the refrigerator”, “cooling in a vacuum-insulated carbonated bottle for 4 hours”, and “leaving it at room temperature for 4 hours”.

I tried to verify the carbonic acid holding power of the Tiger thermos “Vacuum Insulated Carbonated Bottle” –YouTube

Coke that has been kept cold in a vacuum-insulated carbonated bottle has less foaming even when poured into a cup, just like cola immediately after being taken out of the refrigerator.

On the other hand, cola left at room temperature produced a large amount of bubbles the moment it was poured into a cup.

Infrared thermography “FLIR i3As a result of measuring the temperature using “”, the temperature of cola kept cold in a vacuum-insulated carbonated bottle (left) was 13.0 degrees, and that of cola left at room temperature (right) was 23.5 degrees.

When you actually drink and compare, the cola that has been cooled in a vacuum-insulated carbonated bottle cannot be said to be “cold in a kinkin”, but it keeps a sufficient coldness that makes you feel chilly, and the carbonic acid that bursts on your tongue. The stimulus remained. On the other hand, cola left at room temperature is moist and lukewarm, and has carbonic acid.

When I actually used a vacuum-insulated carbonated drink, I could put 500 ml of carbonated drink in it and keep it cool, so it was a bottle that seems to be just right for the purpose of transferring the carbonated drink bought at a vending machine or a convenience store as it is and keeping it cool. .. In addition, the lineup has a maximum capacity of 1.5L, so it is a nice point to be able to select the capacity according to the purpose, such as using it alone in an office or school, or using it for a picnic with multiple people.

The vacuum-insulated carbonated bottle is available in 4 sizes of 0.5L, 0.8L, 1.2L, and 1.5L, and the color lineup is 3 types of copper, emerald, and steel. At the time of writing the article, the 0.5L version is available on Amazon.co.jp for 7980 yen including tax.
