Copper lining shield manufacturing for stainless vacuum insulated bottle tumbler

Copper lining shield manufacturing for stainless vacuum insulated bottle tumbler

Copper lining shield manufacturing for stainless vacuum insulated bottle tumbler

  1. Why need copper lining for stainless steel vacuum insulated bottle tumbler?

An interior copper liner that reduces surface heat loss, to insulate hot liquids for 12 hours and cold for 24 hours or more.

Based on the tests data, with test environment 24+/-2℃,initial 95℃ hot water, we compared the water temperature at the test timing at 1Hour, 2Hour, 4Hour, 6Hour, 8Hour, 12Hour, 24Hour, it’s easy to see the difference between a stainless vacuum insulated bottle with Copper lining & without Copper lining, the average difference is about 15%.

2. Why copper lining shield can affect the vacuum insulation of a thermos bottle to have better heat preservation performance?

As you can see the picture above, the hot/cold drinkiing water stays hot or cold inside the vacuum insulated bottle, becuase the thermos vacuum insulated bottle creates an airless space between two walls which virtually eliminating the convection process and temperature change, and the copper liner can help eiminate the convection process inside the thermos bottle

What’s the Difference? Double Wall Insulated vs Single Wall Water Bottle

 

What’s the Difference? Double Wall Insulated vs Single Wall Water Bottle

What's the Difference? Double Wall Insulated vs Single Wall Water Bottle  What's the Difference? Double Wall Insulated vs Single Wall Water Bottle   VS.   What's the Difference? Double Wall Insulated vs Single Wall Water Bottle

How you choose a water bottle, a stainless steel water bottle, you only want to have a stainless steel bottle for drinking, no any requirement except for food contact safety basic reqirement, or you want the bottle can keep your water liquid hot or cold hours in hot Summer or Cold Winter days, then we have breakdown of the major difference between double wall insulated bottle VS. single wall bottle.

1. Materials:

Single wall bottle & double wall insulated bottle both use Stainless steel, and you need to know what stainless steel material the bottle is?

Stainless steel 18-8 (SUS304); Stainless steel 18-1(SUS201); Stainless steel (SUS316 Medical grade)

These different materials has different quality on the FOOD CONTACT & Anti-Rust corrosion performance.

2. Keep it hot, keep it cold

The most obvious difference between double wall insulated bottle and single wall bottles is how long they hold their water liquid temperatures inside the bottle vessle in the hot Summer Days or cold Winter Days. The insulated bottles can keep cold liquids cold for up to 24 hours and hot liquids hot for up to 12 hours in technically. We can use the double wall insulated bottle for warm coffee and tea throughout the day, or for keeping water (or beer) icy cold after a long day outside.

But you only want to have the water bottle to drink water in a short time, the single wall bottle is good enough and it is much cheap and light for easy carrying on the go.

3. No Sweat

Don’t not want the water bottles sweat? Well, when air comes in contact with a non-insulated bottle with cold water it begins to cool down. If it cools enough, water vapor in the air is condensed and turns to liquid that beads up on the outside of the bottle. With a the double wall vacuum insulated bottle, this doesn’t happen. The outside of the bottle just doesn’t get cold enough when it with cold water inside the bottle, keeping water rings off your table or contents of your bag from getting wet with bottle sweat.

How does a vacuum insulated botle flask reduce heat loss?

HOW DOES A VACUUM INSULATED BOTLE FLASK REDUCE HEAT LOSS

How does a vacuum insulated botle flask reduce heat loss

How does a vacuum insulated botle flask reduce heat loss?

A vacuum insulated bottle flask which known Thermos Flask, Vacuum Flask, Vacuum Bottle, are usually made with double wall stainless steel materials, with a vacuum layer between the double wall to keeps liquid hot or cold long time.

In order to Maximize the heat retention performance, we want to know How does a vacuum insulated botle flask reduce heat loss?

Materials:

Material “stainless steel” won’t affect the heat loss or very little which we can ignore it, the materials only has different cost between different stainless steel becuause their anti-rust grade and food contact grade, such as SUS316, SUS304, SUS201.

Copper lining on inner wall:

copper lining on inner wall can surely improve the heat retention performance 10~15% based on tests on different designs/different sizes of stainless steel vacuum insulated bottle flasks;

Under same test enviroment, with same temperature hot or cold water, bottle with copper lining & bottle without copper lining, measure the temperature from begining, and 1hour, 2hours, 4hours, 6hours, 12hours, 24hours, the heat retention performance has 10~15% difference.

How does a vacuum insulated botle flask reduce heat loss

Bottle Mouth Size:

We need to try design smaller bottle mouth to reduce heat loss, because the main area where heat loss is the bottle mouth, it means the bigger mouth will more heat.

Bottle CAP/Lid:

We need to design the bottle cap/lid to have double wall as what the double wall stainless steel bottle body is, and can add a polyfoam inside the double wall cap, it can help to reduce the heat loss from the cap.

Gaskt location:

The gasket location and desing on the bottle cap, also will affect the heat loss of vacuum insulated bottle, we should design the gasket to seal water leaking inside of the bottle not seal water leaking on the top of the bottle mouth.
