Recommend to you a very interesting vacuum flask from the American brand Revomax.

The design of the lid is very special, and I keep play it when I get it in my hand.

Press the lid of the cup once to open the lid to get the water out.

After being buckled, the lid of the cup seemed to “suck” the body of the cup, and it will closed instantly.

Open and lock the lid in one second, all can be done with one hand.

Most of the common cups have threads on the mouth, and the opening and closing of the cup cover basically depends on “twisting”.

It requires both hands to do it, which is time-consuming and effort.

When twisted wrongly, the cover will loose easily and leak water.

This cup has no threads, so the open is much simpler.

Press the 3 buttons in the red circle at the same time to pull out the lid directly.

Pull the inner ring once, and the lid will automatically lock, and it will be fastened in one second.

You can hang the lid on your fingers while opening the lid, and everything can be do with one hand, super smooth.

Quite suitable for car use, no need to leave the steering wheel with both hands, which make drinking water is quick and safe.

Without the threads in the lid still can be closed tightly.

There are two large buckets of 5L water (10kg) hung on the lid of the cup, which will not be pulled off and is very stable.

Fully sealed design, you can safely put it in the bag.

Don’t be afraid that the lid switch is pressed by the contents of the bag and accidentally opened.

The lid can be only opened by pressing the 3 buttons at the same time, and pressing the outer 2 buttons is useless.

The button in the middle is hidden in the lid of the cup. It is design not to touched by mistake.

The essence of this thermos cup can be said to be on the lid of this cup.

For a small lid, there are many details worth talking about.

There is no thread on the mouth of the cup, and the seal is entirely by the silicone sleeve in the lid (pictured on the right).

Change to a transparent cup, the structure change of the cup lid looks more obvious.

Pull on the inner ring, lock the lid of the cup, and the silicone sleeve will tighten upwards, and the bottom circle is against the cup mouth as the first layer of sealing protection.

The protruding part of the red frame at the top, after being inserted into the lid, can be sealed to serve as a second layer of sealing protection.

Relying on the double-layer sealing design, it can ensure that the cup does not leak water and has a long-term temperature lock.


The thermos cup is sealed and stored for a long time, and there will be a pressure difference between the inside and outside of the cup, and the lid is easy to be sucked and cannot be opened.

It needs to be solved by exhausting. There is a vent hole at the bottom of the lid, which can balance the internal and external air pressure at the moment of opening the lid, helping to open the lid smoothly.

For the decompression and exhaust effect, we did an experiment with soda.

The air-filled liquid in a sealed bottle often has an unbalanced air pressure and lead to “explosion” when opening the bottle (pictured on the right).

Pour Coke into this cup, close the lid and shake, nothing happens after opening the lid, the exhaust effect is superb!


Except for the silicone ring, the lid is made of PP material, which is wear-resistant and durable.

The parts are detachable for easy cleaning.

Press the 3 buttons on the lid to unlock, and separate the parts according to the order shown in the figure.

The installation method is shown.


The cup body is made of 304 stainless steel, with a double-layer structure, which is very solid.

There is a vacuum state between the two layers, blocking internal and external convection and heat dissipation, so it has the function of heat preservation and heat insulation.

The inner tank is also plated with copper to enhance the heat preservation effect.

The caliber is 49mm, which is big enough and it is not difficult to put ice cubes.

The cup mouth is smooth and there is no thread, so there is no need to worry about the liquid volume in the seam and it is difficult to clean.

Straight barrel type bottle body, no dead angle, easy to clean.
