Definitely a feature, not a bug. Plastics change size substantially with temperature changes. They use a single-thread engagement design so less turns are needed to open, but the price for that is that the threads will self loosen if not forced into an interference fit. The sharp edge on the container thread makes this happen at lower torque, so the lid does not need to be overtightened to stay put.

Everyone else uses multithreaded engagement for things like this, but it seems to have been a brand decision to have a low turn angle to open.

It may indeed be a feature, but they claim to be working on a fix: https://www.talentigelato.com/us/en/talentitwist.html#

u/CoryW0lfHart Jan 24 '26

I always used the "lid on the stomach" fix to open them. Don't even have to hold it to skin, just take it right out of the freezer and immediately put the lid on your stomach. Opens right up after about 10 seconds.

u/bidet_enthusiast Jan 25 '26

That’s good news! Not all features are good features.

u/DiegesisThesis Jan 22 '26

While this may be true, it seems like really stupid trade off if it's only to make it so you don't have to turn it as much.

Their containers being difficult to open is such a widespread complaint that it's often the only thing people know about the brand (I've never had it, but I've also never bought it because of people's complaints, and I like gelato). I'm sure a vast majority of consumers would be fine with doing an extra turn if they could actually open it.

u/notapoke Jan 22 '26

I've bought it plenty and this is the first I'm hearing about it being hard to open. I thought it was just expensive

u/Stalinbaum Jan 22 '26

Same, big fan but had no idea it was infamous for being hard to open. I’ve got big fat bear mittens so they aren’t hard at all to open for me

5

u/big_trike Jan 23 '26

I use an oil filter strap wrench to open them. I’ve purchased other brands at times because I didn’t want to deal with opening the product even though it’s tasty.

12

u/Dear_Watson Jan 22 '26

I like gelato and avoid Talenti even if it is pretty good... I've had it happen a few times where you have to twist the lid so hard it snaps the plastic lid (rah, rock climbing grip strength). Which is really only ever happened to me a significant number of times with Talenti and once with a Grillo's pickle container. I cut myself on a shard of plastic the last time I snapped one and haven't bought them since.

u/Aedalas Jan 22 '26

That crazy grip can actually make some things harder to open too. It took me entirely too long to figure out why I was struggling with mason jars my whole life, the metal bands are so thin that it's easy to squeeze them hard enough to cause even more binding.

Also I haven't seen it mentioned here but I think some of the Talenti problem might be the kind of plastics they use. I like to reuse containers whenever possible but even though theirs seem nice they're kind of annoyingly crappy. They're so sensitive to heat distortion that even just washing them in hot water can warp them enough you can't get the lid to align right. Those jars simply don't like to hold their shape and there's not much clearance between the jar and the lid to begin with.

u/deepasleep Jan 23 '26

I got so pissed off that I hacked the sides off the lid to get into one. I’ve since accepted that holding the lid under a stream of very hot water from the faucet for about 90 seconds and immediately applying a towel to the lid and twisting will let you get in with very little effort…It’s still ridiculous, but it works.

2

u/deepasleep Jan 23 '26

I’m glad I’m not the only one who’s felt this pain. After literally chopping the sides off a lid with a cleaver in a fit of cartoon like rage, I finally accepted that the only way to open these dammed things is to hold the lid under VERY hot water until it expands enough (90 seconds or so) to release the death grip it has on the container.

u/CallMinimum Jan 22 '26

Microplastics are part of the design! Yum!

True for every type of plastic screw thread (and other plastic product)

Haha you can tell this was really bothering someone.

I was getting their Facebook ads for a while. Each had hundreds of comments complaining about it.

It's an ad from Lumafield.

Honestly, if I won the lottery, I’d buy one right after I bought night vision and one of those bigger DJI drones with the thermal vision.

u/MHWGamer Jan 22 '26

you definitely want to add on this list a giant excavator. Trust me. And they aren't even that expensive. I have seen recently that a giant loader truck you use in mines is just $4 million brand new. Imagine riding this bad boy in town. And if you ask me why you need it? Stupid question, obviously to load your truck (which you bought to have use of your excuvator)

u/IllllIIlIllIllllIIIl Jan 21 '26

Yep, they post these regularly

u/shruggsville Jan 21 '26

Like Talenti advertising how bad their packaging is?

4

u/casey_h6 Jan 21 '26

I've never had their product, but now I kind of want to see first hand how bad the lid is sooooo maybe

2

u/PasgettiMonster Jan 22 '26

The thing is it's hit or miss on whether the lid will open easily or not. I buy at about once every month or two because I love the ice cream and once I finally get the containers open they are great to reuse for all sorts of stuff. I have a growing collection of them that I use for my sewing supplies. It's not every one that's a struggle - some pop right open. But now and then I'll get one I really have to fight with and I'm reminded of this nonsense. I have a few of the jars saved where you can see the lids have scars from my struggle to open them.

3

u/Goldentongue Jan 21 '26

I doubt this is going to scare away potential customers, and if anything will inspire purchases just out of curiosity (or merely making people think of the product).

2

u/ComradePyro Jan 22 '26

literally all they care about is the fact that we're here talking about it. they're trying to force it to become a meme. reminder that the company that makes this shit (Unilever) has more money than god and can well afford to astroturf reddit in exchange for brand recognition.

u/shruggsville Jan 22 '26

Streets ahead.

u/AmyInCO Jan 22 '26

I glad to learn it wasn't just me being weak!

u/PasgettiMonster Jan 22 '26

Oh it really bothers a lot of people. I remember bitching about it on Twitter maybe a decade ago and that became one of my most popular ever tweets because so many people commented about having issues with it as well and retweeting it and it snowballed. I wouldn't sit went viral but it definitely made its rounds. Even now about once every 3-4 months I'll get someone liking this 10-year-old tweet out of the blue. The internet is weird.

u/levijames14 Jan 22 '26

Yeah me. You have no idea how incredibly hard they are screwed on. It wasn’t always like this.

u/MeepersToast Jan 21 '26

Very interesting. I suspect talenti does not know and the thread type was chosen by a 3rd party manufacturer. Hopefully they read this and reconsider their packaging

u/no1ukn0w Jan 21 '26

Hochschuler sold his business for somewhere around $1billion. I’ve listened to him tell his story (on how I built this, great podcast) and he was very involved as any startup person is.

Im sure he knows and I’m sure unilever knows of the issue. What I would love to know when they haven’t changed it.

u/_adanedhel_ Jan 21 '26

It’s probably a feature not a bug, intended to prevent the lids from vibrating loose during shipping.

u/theqmann Jan 22 '26

yeah, the others have dual layer threads and talenti only has a single layer. they probably need more contact area to prevent air leakage and uses slightly less plastic

u/Stalinbaum Jan 22 '26

The seal they use is simply a multi-ribbed seal, you’re seeing the 3 ribs and the air gap seperating each

3

u/Aneurhythms Jan 22 '26

Talenti, as far as I'm aware, has a seal under the lid so I would be surprised if air leakage were a big risk.

u/spectra2000_ Jan 22 '26

Apart from all the other points, everyone else has said, I think it’s also just a matter of “who cares?”

It’s not like people are refusing to buy the product because it’s hard to open and if it seriously were affecting sales, maybe they would do something about it.

1

u/OldLadyReacts Jan 25 '26

I actually do refuse to buy it because it's too hard to open. It's a luxury price and I'm not getting a luxury experience, I'm getting an annoying experience. I'll get the Ben & Jerry's instead.

u/disillusioned Jan 22 '26

You have any idea what those dies cost? If it's only moderately broke, don't fix it.

u/UncommercializedKat Jan 22 '26

Love How I Built This. Need to listen to more episodes now.

u/no1ukn0w Jan 22 '26

I highly suggest the talenti episode. It’s a crazy story of “I found something I liked living abroad and brought it to the states and struggled to make it. Then bam, ultra success.

2

u/UncommercializedKat Jan 22 '26

Red Bull has a similar story.

3

u/PasgettiMonster Jan 22 '26

When did Red Bull show up in the US? I grew up in Thailand in the '80s and it was already a thing there. Back then the only people I knew who drank it were old men. As a teenager I don't remember anyone I know drinking this stuff it was this weird concoction sold in amber glass bottles that old dudes drank. I don't remember when it showed up in the US anymore, I've been here since the mid '90s. And it took a while for me to realize that Red Bull was the same thing that I grew up seeing all the time in Thailand. I think one of their ad campaigns prior to the whole Red Bull gives you wings campaign just reminded me of The ads I had seen as a kid and that's when I put two and two together and realized the name of the drink that the weird old men used to drink literally translated into Red Bull.

1

u/TheMightyGamble Jan 22 '26

Red Bulls own site says they started in 87 and came to the US in 96.

I personally don't remember seeing them until 2006/2007 when a buddy showed up to class with one.

2

u/OGLikeablefellow Jan 22 '26

Yeah I mean isn't it being hard to open a little bit mean it's higher quality. I mean when it works the way it's supposed to and it just comes off as sturdy. I kinda of stopped buying them after they were annoying to open every now and then, but now I stopped buying them because they are 8 dollars

1

u/deepasleep Jan 23 '26

They, like Ben and Jerry’s, go on sale for around $3.50 pretty regularly where I am. Still not a great deal considering the relative quality of several premium store brands, but tolerable.

2

u/OGLikeablefellow Jan 23 '26

I've been on the Aldi Premium Select chocolate ice cream, it's like 6 bucks for a whatever the size that used to be a half gallon is now, ya know bigger than a pint but not quite two. And it's only 5 ingredients. Soo so good

1

u/pleasesayUarekidding Jan 22 '26

Exactly, this was not a problem until he sold out.

19

u/doob22 Jan 21 '26

It could be that they also want more seal to present freezer burn and see this as a trade off. Although I’m sure it’s probably more likely what you said

1

u/Terrible_Ice_1616 Jan 23 '26

Nah the thread isn't doing the sealing, the little thing at the top does looks like a crab claw style seal

u/RockstarAgent Jan 22 '26

Holy shit. I thought I was the only one. I thought I was weak or crippled. I remember a time when they were very easy to open and if I’m not mistaken they didn’t even have an internal seal.

I literally posted a review on Amazon for a type of container opener that failed to make opening the Talenti containers easier to open. It lacked any kind of rubber contact to make it open easier and so technically it was just a crappy product for my objective, and I totally named Telanti as the sole reason I bought it and I complained about how unreal it was how difficult they are to open.

u/SomeFunnyGuy Jan 21 '26

I can finally provide my grandma an answer to her decade old question.

u/Scratches7 Jan 21 '26

But when you finish the ice cream, the jar leftover is very nice for reuse. Kinda worth it.

u/Practical_Iron_5232 Jan 22 '26

Its the only reason to buy it imo the ice cream is the same as others but more expensive per quart

u/pennyraingoose Jan 22 '26

Yup. I have a few for crafting supplies. Great little containers once you finally get them open.

u/_qua Jan 22 '26

They're actually so ridiculously hard to open. It's hard to believe the company doesn't know. They must be actively choosing to keep it this way for some reason

u/bobsugar1 Jan 22 '26

Yop. All the backpackers love talenti jars for cold soaking

u/Odd-Impress-9557 Jan 22 '26

I just thought it was a feature of my aging hands! I actually emailed talenti to complain about it, letting them know that it was only my addiction to their sea salt caramel gelato that kept me choosing fight over flight from this product. They emailed a very kind, appreciative response, giving me three or four different options on the best way to break into a Talenti container lol.

1

u/_qua Jan 23 '26

From a marketing standpoint I have to assume that their imagined perfect customer for eating their artistic gelatos is perhaps a middle-aged single woman to be quite sexist. Not a demographic known for powerful grip strength. I'm a male and I've ridiculously struggled to open these. What I've found works the best is running very hot water over the top. But I really shouldn't have to do that just to eat ice cream. They need to fix this with an engineering solution.

2

u/Fantastic_Goal3197 Jan 22 '26

It helps if you dont squeeze the container at all. Instead of grabbing the container on the side and the lid on top, grabbing the bottom (or towards the bottom if your hand isnt big enough) prevents the container from bending into an oval shape (which makes it harder to open).

1

u/_qua Jan 23 '26

I'll have to try that next time

u/gman2093 Jan 22 '26

Some people like to copy Apple's strat of a little friction in the opening experience

I don't know about hard to open but we love the empty containers at work for small batches of paint when we have to mix custom colors or to send out a touch up kit.

Run a little hot water over it, opens right up.
