De-Warping a Tupperware lid

I've always thought that Tupperware was microwave safe, and I guess the
bowls are....but not the lids. You'd think I'd learn the first time I
pulled one out and found the lid warped into something resembling a
pringles potato chip, but no, I've effed up a couple of them.

And of course now they won't bite the bowl lip anymore, so they're pretty
much useless. Anyone know how I can get these little bastids to lie flat
again?

Easy, contact your Tupperware distributor. That stuff has a lifetime
guarantee. They should swap it out for you.

Once Upon A Time,

Thanks, but it was bought used on eBay. I took a look online for the
Tupperware "Limited Lifetime Warranty" and it does not mention warping,
just "chipping, cracking, breaking or peeling".

Perhaps putting them in hot water for a while will relax the plastic
out of its warped shape. Let it cool down gradually though. I doubt it
can make them any worse.

Any Foxworthy fans know that tupperware lids have a problem with
microwaves

(at a yard sale). "Tupperware lids that have been warped in the
microwave, six for a quarter. What am I gonna do with tupperware lids
that have been warped in the microwave? Give you a dime for 'em."

I used to own a mind like a steel trap.
Perhaps if I'd specified a brass one, it
wouldn't have rusted like this.

I just saw on another site that you can boil it in a pan of water and while it's still very hot, place a glass plate on top of it with something heavy on the plate and let it cool slowly. It said that this works. I'm gonna try it myself.

Thanks, I'll give it a shot.

I think this is one of the great potential uses for 3-D printing --
making replacements for the little fiddly plastic bits that break
and render an entire assembly useless. How many times
have you had to replace something expensive just because
some little plastic part that would cost less than a dollar -- if
you could buy it -- was broken?

I think your run of the mill 3-D printer would have a hard time printing
something that would have the pliability and resilience to function as a
Tupperware lid.

None that I can think of.

There is no reason why a 3-D printer couldn't print with a more
pliable plastic instead of one that was rigid. As development
of 3-D printers continues, more and more different materials
are being used.

Sure, but how many are available for run-of-the-mill printers? There
are *lot* of things than can be done, if you are not constrained by
cost, availability, or practicality.

I have not been following the developments in 3D printing tech, but
the pliable plastic used in Tupperware lids does not strike me as being
a particularly exotic material. I have no doubt that it is widely available
and relatively inexpensive. Whether it is practical to use in current 3D
printers I cannot say. If it isn't, I would venture that it will be within
a couple of years.

It doesn’t work. Ruined the slightly warped top. Now it’s just a mangled mess. Have to throw it out

Unfortunately, the Tupperware guarantee does not extend to items that you ruin in the microwave unless they are specifically marked as microwave safe. Tupperware should NOT be placed in the microwave unless it is microwave safe. This applies when putting Tupperware in the dishwasher as well. Usually, it is safe to put most pieces in the top rack only, but you do so at your own risk. Unless it says dishwasher safe, the warranty does not apply.

Works great for Rubbermaid products is to put the lid over a microwave safe container with water for a couple minutes. Allow room for air to escape. Flattened my lids right back to form!
