With the recent onset of hot, dry weather conditions, many people are reaching for their vacuum insulated water bottles more often than not. When you’re out and about and need to keep your drink cold or your food fresh, a vacuum insulated water bottle can be the perfect accessory.
A vacuum insulated water bottle purchased via https://www.fjbottle.com/products/vacuum-insulated-water-bottles-family-package-pack-of-5 works by using an airtight seal to keep your drink or food cold or fresh for hours on end. Instead of using metal or plastic to create the seal, manufacturers use a type of insulation called foam. This foam separates gas molecules from liquid molecules, which in turn creates a vacuum.
When the pressure inside the bottle exceeds atmospheric pressure, the pressure equals that inside the insulation and the seal is created. Since these bottles use compression instead of expansion to create their seals, they are not as durable as traditional water bottles made with metal or plastic.
A vacuum insulated water bottle works by using a jacket of air to keep the drink cold or hot for hours at a time. By drawing in air, it creates an insulation barrier around your drink. When you have to open the bottle to take a drink, the high pressure inside the bottle ruptures the insulation, creating a cold or hot burst of liquid that satisfies your thirst!
Vacuum insulated water bottles are also great for adventures because they can keep your drink cold or hot for hours without worrying about breaking them or filling up with condensation. The downside is that vacuum insulated water bottles are not eligible for free refills at most stores, so be sure to bring your own if you plan on using one often.
