Screw on bottle to bottle spout 24/415 thread

A screw on vented spout to transfer the last remnants from a bottle to another.

Designed to fit bottles with a 24/415 thread. In commonly use for various things including cosmetics, shampoo, conditioner, and small spray bottles.

Screw onto the bottle that you want to transfer out from. Tip up and put the spout into the bottle you want to transfer contents to. Then fully invert and let the “from” bottle rest on the “to” bottle until the transfer is complete. See pictures.

A test cap is here https://makerworld.com/en/models/530966#profileId-447789 to check if this will fit your bottle threads.

I also have a 24/415 screw on vented funnel https://makerworld.com/en/models/530906-screw-on-vented-funnel-24-415-thread#profileId-447717
