Non-separating plastic bottle caps - grrrrrr!!!

Ditto.

You first push them down without screwing so they click into place, then tighten them by screwing.

I thought that too. But they don't click.

1. They are much shallower than the old ones, and so are harder for older, more arthritic, hands to open.
2. What is the supposed point of this change?

There seems to have been changes to the caps on the 2 litre plastic milk bottles where the caps are now made of a much thinner and softer white translucent plastic. Counter-intuitively gripping the cap tightly makes it much harder to remove as it deforms and tightens on to the mating tread. I've found when gripping the cap tightly or using a tool the cap is difficult to get off but with a gentle touch using the thumb on one side and a finger of the opposite side the cap will often come off with ease.

Part of the problem with initially opening these bottles is that there is a foil seal under the cap. Once the seal is removed the cap is easier to remove but being made so thin and soft you cannot store an opened bottle on it's without it leaking.

Try looking at this from the manufacturers POV.

Probably helps automate some production process or save a fraction of one pence per item.

The designer may consider re-fitting to be unnecessary.

There is nothing Victor Meldrew about your frustration, it is a crap design a so called improvement over what was before which worked perfectly well.

There is probably some environmental reason behind it with drinks manufacturers trying to virtue signal

Yea It’s little bit tricky to close the cap

But, what’s the purpose for non separating cap? 🤔

When they were introduced, it was stated that the attachment was to make it more likely that the caps are recycled along with the bottle - however, the bottles are bulky and surely everyone squashes them flat and puts the cap on to stop them re-inflating?

OP here. I think it's some sort of green/recycling idea to keep the top with the bottle when it's thrown away.

Exactly the same as the change to the ring-pull beer can that happened decades ago.

I'm sure our local council (Bury MBC) once advised that bottle caps were not recyclable and should go in the general waste. Now it seems to be the form-factor that determines what goes in the recycling bin. If it looks lika a bottle it goes in, irrespective of the material.

Complain. Tesco handed over £10 when I reported this issue to them.

Why can't we make anything properly nowadays - other than a mess of things?

Indeed. I have just checked our council waste advisories and they do say refit the top after cleaning and squash to save space.

I have doubts about the polycarbonate drinks containers where the tops are clearly a different material.

Re: Sigh cling (apparently).

You might be happy with your £10, but it solves nothing and is simply their way of saying "Go away and stop bothering us."

That was to protect wildlife.

What about bottles with metal caps? Usually there is also a metal collar on the neck of the bottle that stays on the bottle, sometimes quite a substantial one.

I wouldn't say perfectly well ... the previous modification of 2 litre screwtops from about 18mm to about 10mm high ensures the pressure required to open them almost rips the skin from your fingers ...

Normally they'd complain about mixed plastics (the bottle is PET and the cap is HDPE).

I see we've been given a four year delay on the "reverse vending machine" scheme for plastic bottles and cans ...

And you've wasted more time with another of your facile comments - and you didn't paid anything for doing so. So, who's the Mug?
