Ankomn turn-n-seal vacuum container : Everything you need to know

Ankomn turn-n-seal vacuum container : Everything you need to know

Suppose you are looking for a vacuum storage container.
You should first know what’s the difference between
airtight, vacuum sealed, and vacuum.

Although many manufacturers call their products one of these,
many products on the market did not meet the definition of those words and confuse customers.

Let’s refresh your memory and experience, and here are the true meanings
if we call a product airtight, vacuum sealed, and vacuum.


Airtight container

A container that can 100% prevent air communication from the
inner container with the outer environment.

An airtight container is abused, now many containers, including well-known brands, call their product an airtight container but fail to do so.

The most simple test method is to put some alcohol in and weigh it.
After a few days weight it again to see if the weight keeps the same
or becomes less.

You will know whether your airtight container is real or not.

How to know if a container is airtight:

In this experiment, we use Everlock(Ankomn airtight container)
to compare with the well-known market product.
We gave 50g of alcohol at both units and 2 days after, weigh it again.
Ankomn remains 50g, meanwhile other brand product loss 8%.
If it's a real airtight it should not lose any weight right?

Vacuum sealed container

A container that creates little pressure difference
(like pressing the lid and squeezing some air out)
between the inner container and the outer environment.

Vacuum container

A container that uses a pump mechanism takes out the air
from the container and reduces the air, and oxygen inside the container.

A vacuum sealed container and vacuum container are easily confused.

If you want a container that can take out the air,
it’s inevitable to have a pump mechanism inside or an extra device to accomplish its job.

The most common way to vacuum a container is using an outer pump, electric drive pump, or a built-in battery pump that allows you to press, turn or pull.


Turn-N-Seal does not belong to any of them,
more close to a built-in pump but a little bit more complex than that.
We will show how the mechanism works in this article.

How to use Turn-N-Seal?

Although the Turn-N-Seal sounds like a complex product,
the way to use it is easy.

  1. Snap the lid on the container
  2. Turn the knob; you can turn in one direction or back and forth. As long as you turn the lid, you are taking out the air. When the vacuum forms, the lock will lock automatically.
  3. To open it. Press to release the air on the pressure balance and pull the knob to open it.

There are two ways to identify whether the container is vacuumed

how to know if the container is vacuumed
  • The gray rubber disinform - low pressure for people expecting to open in a few days
  • You feel that knob is hard to be turned - high pressure for people expecting to keep seal for weeks.

The lid endures tens of thousands of turns, so giving more turns will not break the lid or shorten the life of the product. And rough turns will not hurt the lid. 

The more turn you give to it, the more air you are taking out. There is no limit right there, even if you reach the limit. You can still turn the lid. But no more air will be taken out at this moment.

Here is our recommendation turns for a variety of sizes

Size Recommendation turns
2.4 10 full circle turns
8   full circle turns
6   full circle turns
5   full circle turns
3   full circle turns


What's the technology behind Turn-n-Seal?

The lid has an effort-saving system that will transform your torque force
to drive a pump. Every circle you turn, the pump will be active 32 times
to pump out the air inside.

Will Turn-n-Seal wear quickly or break easily? 

At Ankomn’s lab, we use a robot hand to turn the lid 50000 times with a strong and speedy force. Our lid still works perfectly as new.

The little secret is we used a specific type of material that will self-lubricate in motion, which makes us super confident in its durability.

How long does Turn-n-Seal keep the vacuum? 

We are testing each unit we manufacture and they can all hold the pressure for at least 10 days in an empty situation. Usually, they can hold the pressure longer than this period.

pressure and day variation test

But it will not stay a lifetime, not any vacuum devices on the market can keep a vacuum lifetime, only a few days to a few weeks difference and we are the latter one.

What are the differences between Turn-N-Seal and others?

One of our customers was from Sri Lanka.
He told us he is a wealthy businessman in his country and
his favorite food is called panipuri a local street food you can buy
for a few cents. 
His chef prepares this for him every 2-3 days. However, he is busy eating it in time, whenever he has time to enjoy it. The crispy flavor of the panipuri has gone.
It's quite frustrating when you become a wealthy person but cannot stop this thing from happening. He was trying many ways to store it but failed to do so until he met Turn-N-Seal.
He told us: “That's exactly what I need, you guys don’t know how much effort and time I search for it.”
Now he can enjoy his favorite food storing at Turn-n-Seal, whenever he wants them. 


We know the same story happens whenever we sold a unit.
Many people are looking for great devices but fail to do so.

We believe no one needs a vacuum container;
all we need is a fresh taste and smell.

What Turn-n-seal do is simple, easy to use, and preserves things well.
If you have the same need, try it and you will love it.
