Planning a picnic on a hot summer day? Packed all snacks and now wondering how to carry the drinks without letting them grow warm?

If the answer to these questions is a Yes, we have the best solution for you.

Vacuum Insulated Water Bottles!

These bottles are perfect for outdoor activities such as picnics, trekking, hiking, etc. They have an insulated body that helps retain the temperature of the liquid content, either hotter or cooler, regardless of the outside temperature. 

The popularity of vacuum water bottles has tempted many manufacturers to start their production. But designing such effective vacuum flasks is not as easy as it may seem.

Even so, no worries. This article will help you with tips, suggestions, and features to help you design excellent vacuum flasks and earn a fortune.

Considerations And Suggestions To Design A Vacuum Insulated Water Bottle

 

The Distance Between Both Walls

The usual space between the insulating layers is 3 mm, and the same should not go below 2 mm. There should be enough space between the vacuum layers to achieve effective thermal insulation.

On the other hand, the usual space between the insulating layers at the bottom is 10 mm, and the same should not go below 8 mm. 

If precise space is not maintained, the air pressure will make the bottom of the outer layer deform, further making it touch the bottom of the inner wall.

Thread Design

While designing the thread of the bottle, you must pay attention to:

  • Height of the thread: It should not be above 1.0 mm. Try to maintain the height between 0.5 mm to 0.9 mm to avoid slippage.
  • Pitch of thread: It should be between 4 mm to 5 mm. Less would increase the defect rate, further reducing the product effectiveness, and the working life of the thread will suffer.

The Thickness Of Outer And Inner Walls

If the diameter of the vacuum water bottle is less than 70 mm, use stainless steel with a thickness of 0.4 mm. On the contrary, if the diameter is more than 70 mm, it’s better to get stainless steel with a thickness ranging from 0.5 mm to 0.7 mm. The right thickness will ensure the bottle’s durability and quality.

The Appearance (Because The Same Matters)

All the insulated water bottles available in the market are mostly round. The reason behind the circular structure is that after vacuuming the space between the insulating layers, every point of the bottle bears even huge air pressure, which the circular structure withstands without any deformity. The round-shaped bottles can perform the “insulating part” more confidently than any other shape.

The Location Of The Vacuuming Point

The vacuuming point in every insulated bottle is set at the bottom’s center to ensure even air force on the bottom. Before vacuuming, manufacturers should ensure to punch a hole in the middle of the outer wall of the bottom and vacuum from the hole’s position. The location of the vacuuming point will not degrade the bottle’s appearance. It will also prevent deformation from the strong suction.

Silicone Seal Gasket

There are two types of sealing designs: top-sealing and side-sealing. Top-sealing is a cola-shaped bottle lid, whereas side-sealing serves for pressed-in lids.

The thickness for the top-sealing lid should fall between 2 mm to 3 mm, and for side-sealing, it should be 1 mm.

Selecting The Right Metal Material

Two types of stainless steel are mostly used to manufacture vacuum bottles: 18/8 stainless steel and 316 stainless steel. If you want your bottles to pass the FDA test, choose the material cautiously.

Selecting The Right Material For Lid

It’s better to use BPA-free materials like AS, Tritan, and PP. Always choose the best quality material to ensure the long and effective working of the lids and keep customer satisfaction level at the top.

Other Tips In designing To Ensure The Best Thermal Insulation

  • Reduce the diameter of the bottle’s mouth.
  • Use a stopper to decrease heat conduction from the mouth of the bottle.
  • It’s better to go for copper platting for the outer side of the inner wall.
  • To increase the space between the insulating layers, you can wrap aluminum foil on the outer side of the bottle’s inner wall.
  • Increase the capacity of the vacuum bottle because the larger the capacity, the better will be the heat preservation and the better will be the bottle’s temperature retention capability.

Wrapping Up

Vacuum water bottles or vacuum flasks are becoming immensely popular all around the globe. They, along with maintaining the freshness and temperature of your beverage, take care of your health. As also mentioned above, the bottles are made from the best quality stainless steel that poses no threat to your health.

Additionally, insulated bottles are a perfect alternative to plastic bottles that deteriorate our environment’s health. So, by switching to plastic bottles, you can stay healthy and live in a healthy ecosystem.
