Why does the lid become a problem less than 2 months after use. It does not snap into place as it had been doing, and taking it off is a contest.

I have the same problem as the others here. I have to use a still-son wrench to get mine off. I have applied pool lubricate to the lid but it has not helped. It would be interesting to have the manufacture respond to this problem on this forum. How about it Amazon?

I anticipated trouble based on my older uni so I bought a strap wrench at Sears. From my pool supplier I bought a tube of Jacks 327 for $9.95. I put it on the threads and find I can remove the cap wirh one hand. No problem in tightening to the "click".

The newer ones are worse than the older ones. But someone else suggested using a mallet to tap it loose, then untighten by hand. Same for closing. It works--but it's the only way it works for me. There may be a lubricant to help it slide, but I haven't used one. Sad to say, but I keep a new one of these with my pool stuff just in case the old one stops working.

I have same problem, It is not the lid but the "O" ring. The "O" ring becomes swollen and then makes the lid hard to shut. However I have replaced with a new one and it is still hard to remove and install. I am in the process of trying to trouble shoot this problem so I can share with others what to do.

I have the model and use it in a salt water sea pool. My local pool supply recommended that I use a Teflon base lubricant that makes it easier to open and close. I have also made a wood wrench that fits over the top so I can get a better grip. It is 4 inches longer than the width of the top and notched so the wrench fits over the top. I also change the O-Ring gasket once each year. Hope this helps.

This is my second feeder over 10 years. Both started sticking after a few months. I don't close it as tight any more. Close it just enough so it does not leak.

I have a problem with the lid sometimes too. I noticed when I leave the top flap open also when I screw the lid on it doesn't give me that problem as well.

I purchased mine in October and have used it weekly. The lid comes off reasonably easy and goes back on fairly quick.

Try removing, cleaning, and re-installing the rubber o-ring. Make sure it is seated in its groove. How it could work for 8 weeks and stop working, I don't quite get, but there must be something out-of-kilter. For sure, remove the o-ring and then simply test whether the lid goes on straight-away, if so, the o-ring is most likely not seated well.

Same thing. The lid to my container stopped locking, and I emailed the company customer service and they sent me a replacement lid.

I have the same problem. Two of my lids broke. I just emailed Thermos, so I will just have to wait and see what they say.

The lid should be pushed down until it snaps into place. Once in place it will not move.

The lid will not come off until you lift the little rubber knob holding out the air. If it is new, it takes a couple of tries before you get it to seal. It need to be broken in a bit. After that it seals quickly. It is great for lunch meats and cheeses. Hope this helps you.

The lid slides off when you press in the button on the side of it. That same button helps air escape when you put the lid back on.

Keep turning the lid counter clockwise and it will come off. It has a little resistance to show when in the open to drink position. You just turn past it and the lid comes odd.

I never had the lid get stuck, but I've experienced the cups bottom getting stuck so I just carefully lifted it up. Perhaps you could do the same in the opposite direction.

No, not in my experience. The lid is a hard plastic, I can't see that ever happening.

No problems. I love this lid. I bought 2. It been about 6 months. Easy to clean.

My lid just developed a hole in it, too. I'm just curious if your lid is sporting a perfect circle right in the center? (That's what mine looks like.)

Try taking the lid off when it is not sealed. Then seal it and try it again. You'll have major trouble removing the lid if it's sealed.

I don't have this problem. Check if the top inside plate and other removable items on the lid are tightly snapped in.
