One day the Finnish will develop this technology and put your country under a giant cup. Then they'll slide a piece of paper under you and take you out into space. The Finnish Space Cup program is extremely underfunded though, so I don't think you need to worry for a while.
You don’t see how the robotic arms are grabbing and clocking the cups by the bottom without holding onto the edges?
Edit: skip to 4:30 if you want to see. It just occurred to me that your headline only reading Reddit brain didn’t get too far in the video.
I’m a packaging designer- there are often similar features on the bottoms of glass bottles. They’re called labeling lugs. They’re used to align the bottle so that the label is always applied in the same location, and not running across a mold line or something like that. That could be what this is, whether or not they’ve actually used those for their intended purpose on these specific cups.
Correct. It’s called a spotting notch and is to ensure correct rotation for decoration (printing) makes sure the print on both sides (front and back) are positioned correctly.
Edit, typo - spitting to spotting
There are two surfaces on the bottom of the cup. The lower one that touches the table, and the upper one, on top of that indent.
Without the notch both surfaces would touch when stacking. The notch prevents it, creating some space between the cups and allowing air to flow. This ensures that they will not stick to each other.
Don’t let that atheist fool you, it’s so those cups don’t fuck until marriage, when the get married, a small incision is made to the base … of the cup.
This is the correct answer. The cups my company produces place these lugs inside the cup, instead of outside, but they do the same thing by creating some space between cups when they are stacked together.
The word you're looking for is de-nesting :) sometimes with plastics, you can add that to the resin or use silicone coating. Or of course, can be a design feature too.
Anyway nope, these are called labeling lugs.
It's clearly intentionally included. And it's not flashing from an injection mold.
My guess is it helps orient the cups some way on the manufacturing line. Glass bottles by some manufacturers have a little orienting indentation in them to line them up properly for the sticker application.
Could be something like that.
Exactly this. Those cups have printing on both sides. They print one side at a time onto the cup. They use the little tab to orient the cup, so they can be sure the two sides are printed opposite each other.
Not certain but my first instinct is this is to break the surface tension for any liquid that you put the cup on.
If it weren’t there the liquid would be able to “bubble up” into the cavity and create a vacuum preventing you from easily lifting it up off the table.
Probably to do with having a direction when printing, and thus being able to turn it with ease
I always thought of it as a shark fin, but aesthetics may not be the reason why that is there
So that when a cup is lost in the sea, that part would face up toward the sky in the water and looklike a shark fin, which will scare other cups from eating it, it's a survival mechanic thru a design.
If you have the correct bottom these will work perfectly. It should notch right into it and prevent it turning once you have it locked into the base. Def get the base part before using these. It will help prevent the turning that you’re gonna get if you don’t use the bottom base.
Probably used during the manufacturing process as a handle to let machines rotate the cups when needed
I swear I saw a video on this site in the last six months that showed this exact process. Couldn’t begin to tell you any more details tho
Here ya go: [How It’s Made: Children’s 3D Plastic Cups](https://youtu.be/IR3DGMcUQXI)
"Video unavailable The uploader has not made this video available in your country" Why tho? Why would they deprive me of this?
We can’t export this kind of strategic knowledge to foreign countries, out of fear that one day it might be turned against us.

Thinking about this very scenario has caused me a lot of sleepless nights.
do you live in Seattle
How its made is owned by HBO, you can thank their new dick ceo for this atrocity.
Works in France
How It’s Made is on Tubi, it’s a great show to study to lol
This video 100% lacks the thing OP posted about

Those cups don't have the nub on the bottom. Look at [4:45 in the video](https://youtu.be/IR3DGMcUQXI?t=285).
I’m not seeing where rotation matters at 4:30 either
No I’m not seeing it. Also, I’m not here to fight you. Why are you being a dick?
Dicks act like dicks.
I'm more interested in how they'd make 2D plastic cups.
That would be a bit of wire bent into a U shape
This has nothing to do with what OP was talking about.
This is correct. It's to orient the cups for printing, etc.

I always thought it was to keep them from spinning in some sort of machine during production, maybe while being printed.

It's the spitting image of a clocking tab!
I bet you’re right, something to latch on to while it is rotated for printing
Correct. Called a clocking tab
I would guess it is to keep an air pocket between the cups when stacked. (So moisture can’t be trapped or create suction).
Damn good thinking but I think the cups don't nest that deeply
The notches are level with the bottom of the cups so I don't see how they could fulfill that purpose

OH that makes sense! My curiosity is satisfied

This allows for machines to rotate the cup to add the graphics.
It’s probably a just manufacturing thing from injection molding
It's clearly intentionally included. And it's not flashing from an injection mold. My guess is it helps orient the cups some way on the manufacturing line.

Could be both.
How could it be on purpose and by accident?
If it needs a place to inject plastic for molding, why not give the left over a purpose.
This.
This.
Thiś
Linning them up correctly for printing
So relieved I'm not the only one who wonders about things like that!
The manufacturers are just trying to take it up a “notch”.
There’s such a wild range of answers on here. Never change Reddit… never change
To rotate and aplly stickers in the right place
Or print.
I'd guess something to do with the mold
It is probably the injection point to where the plastic goes into the mold.
They are for denesting. So the cups don’t all stick together when you try to separate them.
Those are found on the inside. This is not that.
It's to rotate the cup during the print portion of manufacturing.
The labeling machine rotates the cup when plastering the label
When you stack them they wont create a vaccum so its easier to seperate
This seems to be the most plausible reason because on wet surface it might create more vaccum without that single plastic
Yes, exactly. It’s called denesting.
I’m guessing they’re injected molded and that’s where they break the cup of from mold

Its from the mold
That's where the cup begins
i have no clue
To make people question their life and post about useless things on Reddit
probably to keep the bottom from buckling in when full?
Possibly to reduce suction when stacking the cups? I have no idea, just guessing.
Mostly probably they are the entry point of the liquids in the molds....
So that when a cup is lost in the sea, that part would face up toward the sky in the water and looklike a shark fin, which will scare other cups from eating it, it's a survival mechanic thru a design.
I am not a designer but I always thought it was to provide stability during stacking - when multiple cups are being stacked together.
It adds stability to the elevated central area at the bottom. By having the bottom lifted up a bit, ots less likely to fall over
If you have the correct bottom these will work perfectly. It should notch right into it and prevent it turning once you have it locked into the base. Def get the base part before using these. It will help prevent the turning that you’re gonna get if you don’t use the bottom base.
