Insulated bottle

To face summer or winter, think of the reusable insulated bottle! This famous bottle with isothermal properties was first marketed under the brand name 'Thermos'. Actually, this bottle is widely known simply as a 'Thermos' although it is a registered trademark and there are now many brands marketing this type of product.

Guaranteed bfa-free and hermetically sealed, AZ Boutique’s range of insulated bottles includes articles of prestigious brands such as Thermos or Ibili. Some models of this double wall, leak-proof insulated bottle will keep you warm or cold for more than ten hours, some models even up to 24 hours !

How does the insulated bottle also known as the thermos flask work?

In a normal bottle your drink will equilibrate with the ambient temperature either by thermal conduction or radiation. Your thermos flask has an ergonomic design that is specially designed to minimize the contact surface of your hot or cold drink with the ambient air.

The insulated bottle actually consists of two bottles nested inside each other and an air gap is created between the two to prevent heat conduction.

However, this air gap does not prevent heat exchange by thermal radiation, to compensate for this, the inner surface of your bottle is covered with a special reflective layer.

How to optimize the performance of your stainless steel insulated bottle?

To keep your drinks hot for as long as possible, simply pour hot water a few minutes before using them. This boiling water will preheat the inside walls of your insulated container and this will minimise heat loss once you pour your hot chocolate or coffee into it. Then fill your container as much as possible to remove any air space. You can use these techniques to optimize the thermal performance of your insulated flask, insulated jug or insulated mug.

For a cold drink, you should therefore pour cold water into your bottle before pouring the drink you wish to carry in order to lower the starting temperature of your container.

Which insulated bottle should I choose ?

Family size bottle with a capacity of 1500ml or rather individual bottle of 500ml, AZ Boutique offers you a selection of insulated bottles of different capacities.

However, you should know that a fully filled 500ml bottle will keep your drink at the right temperature much longer than a half-filled 1000ml bottle. The majority of the insulated bottles are equipped with a screwed cup, so you can pour your drink into it, evaluate the temperature and let it cool down if necessary. It is very handy to avoid burning yourself !

Some models in the Thermos King range have a heat storage life of 24 hours: ideal for very long journeys or hikes. An essential part of the modern nomad's panoply!

The wide opening of the 'Thermos' allows you to put ice cubes in and wash it easily.
