Materials of vacuum insulated bottle:

Vacuum Bottle Body:

SUS304; SUS201; equal to Stainless steel 18/8; Stainless steel 18/1

SUS201 only can apply for outer wall of vacuum bottle, because it’s not food grade material, also much easy to get rust when have contact with liquid.

Usually top brand vacuum bottle has double wall stainless steel 18/8 (SUS304) to have better quality.

Vacuum Bottle Cap:

Tritan or PP plastic materials, both are BPA Free (when we discuss BPA Free material, it aim at protect children’ healthy hydration drinking, especially with hot liquid), toxic free, FDA LFGB comply

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.

Now we have the answers for this question;

  1. Designs (bottle mouth, cap, gasket)
  2. Copper lining

Raw Materials

Lid/Cap: Plastic “polypropylene or Tritan”, usually is polypropylene, they are both food frade, FDA comply, polypropylene is much cheaper and easier to be manufactured.

Gaskt: silicone rubber

 

Bottle Flask Body: Stainless steel “SUS304 or SUS201”, usually is SUS 304 “18-8”, SUS201 is easier to get rust and not food grade, but much cheaper, some low end brands or promotion market is using SUS201 to make stainless steel bottles

The Manufacturing Process

Vacuum Insulated Bottle

How Vacuum insulated bottle is made?

  1. Manufacture double wall stainless steel: “Outer wall & inner wall”, manufacture the shape and size as design drawing specs.
  2. Copper Coating: copper coating on the inner wall which enhancing heat preservation performance
  3. Welding: welding the mouth edge, bottom
  4. Grinding: grinding the welding seam
  5. Vacuum Process: create vacuum space between double wall, and test 100% vacuum insulation
  6. Electrolysis: electrolysis process to create a inert layer on the surface of inner wall to make it good surface and not easy  to get rust.
  7. Polishing:polishing the bottle flask to have good quality surface.
  8. Vacuum Test: test vacuum insulation of stainless steel bottle flask 100% again
  9. Surface treatment: different options for surface treatment, such as spray painting, powder coating, water transfer etc.
  10. Custom printing: custom printing with different method, such as pad printing, heat transfer printing, laser etching etc.
  11. Inspection and assembly: inspection, asembly with lids, gasket, sleeve, gift box

The top lid/cap

How vacuum insulated bottle is madeHow vacuum insulated bottle is made

  1. the top lid/cap of bottle flask is made with plastic material usually, and it is made with injection machine
  2. with stainless steel material made top lid/cap, it is manufacture the lid then welding the top cover with base lid together, and grinding the welding seam and polishing.
  3. with stainless steel material made base lid and plastic made top cover, put stainless steel base lid on injection mould then process injection to have combined stainless steel/plastic lid/cap

Quality Control:

The most important of stainless steel vacuum insulated bottle flask is vacuum insulation, that’s why we have double “vacuum insulation test” during the whole manufacturing process.

The raw material cost is very important for high end quality stainless steel bottles, we recommend 18-8 Food grade stainless steel.

The polishing quality is very important if no any other surface treatment, our company set full inspection after polising process.

Different surface treatment has different features, we can choose the best way to meet the bottle design and market needs.

Final inspection of your stainless steel vacuum insulated bottle flask is during/after the assembly/packing line.

The Features:

How vacuum insulated bottle is madeThe stainless steel vacuum insulated bottle flask keeps hot liquid 12 Hours longer and cold liquid 24 Hours, it based on the manufacturing process and quality control, also affect by the bottle designs.

 

With cold water drinking, you don’t need to worry about BPA which only appear when with hot water inside your drinking bottle veseels, when you considering drinking hot water, you need to know what materials your stainless steel water bottle made, choose BPA Free material made bottle products in the market.

How vacuum insulation affect heat retention for your vacuum insulated container?How vacuum insulation affect heat retention for your vacuum insulated container?

How we can design and manufacture a good vacuum insulated container which has great vacuum insulation to achieve good heat retention for keeping hot/cold long time enough?

Before discuss manufacturing techique, we would like to have review for your design of vacuum vessel/jar as follow;

  1. the open mouth which escape heat inside the vacuum container, try to minimize open mouth to provent heat escape from the mouth as low as you can.
  2. the welding station on the open mouth of your vacuum insulated container which means the more non-insulated area you have on the vacuum vessels, the more heat would escape from the non-insulated area, because metal is very easy to transfer heat energy, we got to try to minimize the non-insulated area, of course, it’s also depends on the manufacturing techique to achieve this needs.
  3. the leaking-seal station, try to minimize the space where heat escape for your vacuum insulated bottles.

Anyway, whatever we trying to do is minimize the heat transfer/escape from the vacuum insulated bottle/container on design aspects to achieve great heat retention.

When finish a vacuum insulated bottle/container design, and evaluated all is could be manufactured, we can focus on every step during manufacturing to get a good heat retention quality products.
