I tried using the long-awaited 'Cat Tongue Senka Tumbler' that can keep drinks warm for a long time at 'just right temperature'

When working in an air-conditioned room, I would like to have a hot drink by my side, but a person with a cat tongue says, 'I want to drink a hot drink, but the stainless steel tumbler is too warm to keep warm. We tend to face the problem of 'not getting the right temperature'. ' Cat Tongue Senka Tumbler ' is a tumbler developed for people with such cat tongues, and it keeps hot drinks warm for a long time at just the right temperature without being too hot. I asked, 'Does it really keep the temperature easy to drink ...?', So I actually compared the heat retention performance with other tumblers and checked it.

◆ I opened the cat tongue tumbler
The package of the cat tongue tumbler looks like this. The cat tongue tumbler is available in four colors: black, pink, white, and green. I bought green this time.

Inside the box was a cat tongue tumbler and instructions.

The cat tongue tumbler has a shape that gradually thickens from the bottom to the top.

It looks like this when comparing the size side by side with

the iPhone 12 with a long side of 146.7 mm. The height is 15.9 cm, the diameter of the bottom is 6.9 cm, the diameter of the thickest part is 8.8 cm, and the actual capacity is 0.32 liters.

When weighed empty, it weighed 394 grams.

The surface of the cat tongue tumbler is processed to have a rough texture, making it difficult to slip when held by hand.

The lid is equipped with a slide mechanism to prevent dust from entering through the spout.

The lid is a type that is pushed in without being screwed.

The inside looks like this.

The lid was not completely sealed, and when the cat tongue tumbler was turned over with water actually in it, water leaked from the slide mechanism. The lid is intended to keep warm and protect it from dust, so it seems that it is not suitable for carrying like a water bottle.

◆ Check heat retention performance

We have prepared a cat tongue tumbler, a vacuum insulated water bottle , a vacuum insulated tumbler, and a mug of pottery to see if the cat tongue tumbler can keep the drink warm at a temperature that is easy for people with a cat tongue to drink. Fill each container with boiling water until about 8 minutes, cover the container that can be covered, and measure the temperature change over time with the thermo camera 'FLIR ONE Pro'. When the editorial staff of the cat tongue measured the water temperature that they felt was the optimum temperature in advance, it was felt that about 65 to 55 degrees was 'the optimum temperature that was neither too hot nor too lukewarm.'

First, immediately after adding boiling water, the cat tongue specialty tumbler is 81.6 degrees, the vacuum insulated water bottle is 81.5 degrees, and the vacuum insulated tumbler is 81.7 degrees. Since the maximum simultaneous measurement points of FLIR ONE Pro are 3, the water temperature of the mug is not shown in the image below, but it was 82.4 degrees when measured individually.

If you put the lid on the one with a lid and open the lid after 3 minutes and measure the water temperature, the cat tongue specialty tumbler is 79.8 degrees, the vacuum insulated water bottle is 82.1 degrees, the vacuum insulated tumbler is 78.2 degrees, the pottery mug is 72.2 degrees It went down to.

When I put the lid on the one with the lid again and measured it again 10 minutes after the start of measurement, the temperature of the cat tongue tumbler dropped to 70.2 degrees, and it became a temperature that even the editorial staff of the cat tongue could manage to drink. The vacuum-insulated water bottle is 75.9 degrees Celsius, and the editorial staff of the cat tongue is very hot. The vacuum insulation tumbler is 64.2 degrees, and the pottery mug is 62.5 degrees, which is a water temperature that feels appropriate.

Furthermore, 60 minutes after the start of measurement with the lid on, the temperature of the cat tongue tumbler was 63.0 degrees, which was a temperature that the editorial staff of the cat tongue could enjoy the warmth. However, the vacuum insulated water bottle still maintains a high temperature of 72.0 degrees. On the contrary, the vacuum-insulated tumbler dropped to 45.4 degrees and the pottery mug dropped to 36.3 degrees, making it feel slimy.

The graph below shows the cat tongue specialty tumbler (blue), vacuum-insulated water bottle (red), vacuum-insulated tumbler (yellow), and pottery mug (green) at the time of 3 minutes, 10 minutes, 30 minutes, 60 minutes, and 90 minutes. It shows the water temperature, and the background of 65 to 55 degrees, which the editorial staff felt was appropriate, is painted orange. If you check the graph, the temperature of the cat tongue special course tumbler drops to about 6 degrees lower than the vacuum insulated water bottle 30 minutes after the boiling water is added, and it keeps the temperature lower than the vacuum insulated water bottle after that. You can also see that the temperature of the cat tongue tumbler drops more slowly than the vacuum insulation tumbler and the pottery mug, and the optimum temperature continues for a long time. Focusing on the time when the temperature is maintained at an appropriate temperature (65 to 55 degrees), a vacuum-insulated tumbler is suitable if you can drink within 10 to 30 minutes after making a drink, and a cat tongue if you drink slowly over 1 hour. It seems that the specialized tumbler is more suitable.

◆ Points to be worried about

When I checked the Amazon review of the cat tongue tumbler, there was an opinion that 'the paint is easy to peel off'. When I actually rubbed the boundary between the green paint and the silver part with my nails, the paint came off.

Also, according to another

Amazon review , the claw part is easily damaged when removing the slide mechanism of the lid. When I actually attached and detached the slide mechanism about 10 times, the individual I tried this time did not break. However, it seems that damage is unavoidable due to the mechanism of the nails if it is repeatedly attached and detached for cleaning.

◆ Summary
When I actually tried using the Cat Tongue Senka Tumbler, it had the ideal heat retention performance for the cat tongue, which was that the temperature lower than the vacuum insulated water bottle lasted longer than the vacuum insulated tumbler. However, there are some points to worry about, such as the paint being easily peeled off and the parts being damaged, so it seems that careful handling is required to continue using it for a long time.
