How Vacuum Bottles and Mugs Keep Drinks Hot or Cold – and Why They're Perfect Promotional Products
Posted by Tell and Sell Ltd on 9th Apr 2025
Whether you're sipping a hot coffee on a winter morning or staying refreshed with ice-cold water on a summer hike, vacuum bottles and mugs are your everyday heroes. But have you ever wondered how they actually work? And why are they among the most popular promotional products in New Zealand? Let's take a closer look at what makes these insulated drinkware items so effective — and how they can be a powerful tool for your brand when sourced through Tell and Sell Ltd, your go-to provider for promotional products NZ wide.
The Science Behind the Insulation
Vacuum bottles and mugs are designed using double-wall insulation technology. Here’s what happens:
-
Two Walls, One Vacuum: These bottles and mugs have two stainless steel walls with a vacuum (an area devoid of air) in between. Since heat transfer requires a medium (like air), the vacuum slows down the movement of heat.
-
Keeps Hot Things Hot: For hot beverages, the vacuum prevents heat from escaping through conduction or convection, maintaining warmth for hours.
-
Keeps Cold Things Cold: Similarly, for cold drinks, it blocks outside heat from warming up the contents, so your iced tea stays chilled longer.
In short, it's a smart little physics trick that turns your regular drink bottle into a temperature-holding powerhouse!
Why Vacuum Drinkware Makes Ideal Promotional Products
When it comes to promotional items, you want something that’s useful, durable, and visible — vacuum bottles and mugs check all the boxes. Here’s why:
-
Everyday Use: People take them to work, the gym, hikes, and road trips — ensuring your brand travels with them.
-
Large Branding Space: These bottles offer great surface area for logos, messages, or designs.
-
Eco-Friendly Appeal: Reusable drinkware aligns with sustainability values, which is a big plus for modern brands.
-
Long Lifespan: Unlike paper flyers or pens that get lost, a high-quality vacuum bottle lasts for years.
