Tips & tricks for handling our vacuum flasks/bottles
Instructions for use can be found under the “ Downloads
” menu item .
Before first use:
We recommend that you rinse your new vacuum flask/bottle two to three times with hot (not boiling) water before first use.
- Please NEVER drink directly from the jug or bottle, but use a container into which you pour your drink (risk of scalding!).
- Avoid using metal objects (e.g. metal spoons or similar)
- Check your vacuum flask or bottle for damage before each use.
- Not microwave safe.
- Not suitable for dishwashers.
- Do not use the vacuum jug/bottle to keep milk products or baby food warm (danger of bacteria).
- It is not intended to be used for medical or experimental purposes.
- The items should not be left to children unattended.
Keep warm function:
In order to keep your drink warm for up to 24 hours, please first rinse the jug/bottle with warm water and fill it with hot water. After about 5 minutes, pour out the water and pour in the desired hot drink.
Keep cold function:
To keep your drink cold for up to 36 hours, fill the vacuum jug/bottle with cold water before pouring in the desired cold drink. After about 5 minutes, pour out the water and pour in the desired cold drink. Under no circumstances should ice cubes be used for additional cooling! After 36 hours, the liquid temperature increases by a maximum of 3 °C.
Brew tea directly in the pot:
Place the tea bag (not a metal tea infuser!) directly into the pot and place the string over the handle. Now your tea can develop its aroma within the specified brewing time.
The correct filling quantity:
Do not fill the jug/bottle to the brim (Caution! Danger of scalding due to overflowing liquid!). Please leave approx. 2 cm of space up to the edge of the glass neck. Also avoid submerging the screw cap in the drink.
Please only use the vacuum jug/bottle in a vertical position. Close it by putting the screw cap on and turning it to the right.
We recommend that you turn the lid again after approx. 5 minutes.
The sealing pressure of your new jug should be checked regularly after use and can be increased again by turning the base to the right. For products with a ground screw, tighten them lightly and carefully.
Turn the screw cap half a turn to the left while holding the jug/bottle vertically.
Now you can slowly tilt the vacuum jug forward and start pouring.
For correct cleaning, it is advisable to clean the jug/bottle, the glass insert and the screw cap with a soft cloth or sponge under warm, running water.
Never use alcohol or spirits!
Use our cleaning beads for coffee and tea brews (you can get these in our webshop). The exact description of how to use it can also be found on our website.
Streaks in the glass are possible due to production technology, but have no influence on the usability/insulating function or the quality of the glass body.
