So funktioniert der Adapter

Adapter auf deine Markenflasche schrauben, dann den LIINI Flaschenwärmer kopfüber mit Flasche und Inhalt verschrauben – fertig. Die Milch wird in der eigenen Flasche erwärmt, ganz ohne Umschütten. Funktioniert mit allen LIINI Flaschenwärmern: unterwegs mit Akku und zuhause mit dem LIINI® Home 230V.

Für welche Flaschen passt er?

Die kompatiblen Flaschenmarken stehen oben im Produktnamen. Achtung bei Marken mit mehreren Flaschenlinien (enger vs. breiter Hals): Im Zweifel hilft die Adapter-Übersicht – oder frag unseren Support mit deinem Flaschenmodell, wir antworten 7 Tage die Woche.

Reinigung & Ersatzdichtung

Nach Gebrauch kurz mit warmem Wasser abspülen und trocknen lassen – mehr braucht der Adapter nicht. Jeder Adapter hat seine eigene, passgenaue Dichtung. Sie ist ein Verschleissteil und einzeln erhältlich – beim Bestellen einfach deine Adapter-Marke auswählen, damit dein Adapter so lange hält wie dein Flaschenwärmer.

Versand & Rückgabe

Wir sind ein Schweizer Unternehmen: Versand ab unserem CH-Lager mit der Schweizerischen Post – in 1–2 Werktagen bei dir. Gratis Versand ab CHF 50.–. Retouren unkompliziert, Support 7 Tage die Woche.

How to find the perfect ring size

Do you already have another ring at home?

Yes - measure ring

If you already have a good fitting ring, you can use that to determine the size.

Step 1: Prepare material

  • An existing ring that fits well
  • A ruler or tape measure
  • A pen and a sheet of paper

Step 2: Measure the existing ring

Lay the existing ring flat on a flat surface. Make sure that it does not deform or twist. Use the ruler or tape measure to measure the inside diameter of the ring. This is the distance from one inner edge to the opposite inner edge of the ring. Note the measurement in millimeters.

Step 3: Compare with our size chart

Now compare the measurement you noted with our size scale and choose the appropriate ring size.

No - Measure finger

If you don’t have a matching ring at home, you can easily determine your size with the following procedure.

Step 1: Prepare material

  • A thin strip of paper or a piece of string
  • A pen
  • One pair of scissors
  • A ruler or tape measure

Step 2: Measure the circumference of the finger

Wrap the thin strip of paper or string around the finger you want to wear the ring on. Make sure the strip fits snugly, but not too tight or too loose. Use a pencil to mark the place where the strip or string overlaps.

Step 3: Check the size

To make sure that the determined ring size is correct, you can wrap the thin paper strip or string around your finger again and place the ring on it. Check that it fits comfortably and is not too loose or too tight. Repeat this step if necessary to find the optimal size.

Tip: If you want more accurate measurements, you can repeat the process several times and take the average of the measurements.

Step 4: Compare with our size chart

Now compare the measurement you noted with our size scale and choose the appropriate ring size.
