These swing top caps are made in Europe with our custom Flowing and Growing logo. These caps are the European standard for ALL flip top bottles produced there. The cap is made of BPA-Free Polypropylene and the light blue seal is made of Thermoplastic Elastomere and will not degrade as rubber gaskets do. They will last wonderfully on your bottles.
It is important to clean them from time to time. We like to use our Blue Love Probiotic All Purpose Soap or Grapefruit Seed Extract, both available on our site. You may also use hydrogen peroxide or white vinegar. If you live in a damp moldy climate, it is important to clean them more often. Be sure to check on your cap gasket. If you see black on it, it has grown mold which is very difficult to get rid of! With regular cleaning of the cap and bottle, you will avoid this situation. Please see our Care for your Bottle section to learn more.
All of our smaller (500ml 750 ml and 1 liter) bottles come with these caps, so there is no need to buy one unless you just want to have them on hand for the future, or for other Blue Bottle Love bottles you bought in the past. As they are custom made for our bottles, we cannot ensure that they will fit another type of Flip-Top Bottle besides Blue Bottle Love.
In addition, if you use the dishwasher to clean your bottle, we recommend you remove the cap before doing so. You will need to pry one side out away from the prong socket, then the rest of the cap will come off easily.
You can be sure you have a authentic Blue Bottle Love water bottle when you see the Custom Light Blue Gasket as well as our logo on the cap!
