How to fix a defective tumbler lid? Answered
I bought this tumbler a week ago and I just found out that the lid keeps popping up. At first, it was only a problem when it contains warm beverage. Now, it never closes even when empty. I cannot put it in my bag without the risk of spilling liquids on my stuff.
Replacing it is not an option because in the first place, I bought it to reduce use of disposables. Add to that that I am a student on a tight budget. I've thought of gluing the lid shut completely, and simply use it like a screw-type lid, but then I'm not sure what type of glue is food-safe yet waterproof.
- Lid is flat when closed.
- After a few seconds, it pops open.
- The inside of the lid when closed. I suspect the rubber that is supposed to lock it in place is not enough.
- The lid structure when open.
Looking forward to a *lead* to fix this lid ^-^
