Faulty Lidl Milk?

[NottmArt]

Each week by buy Lidl Dairy Manor long life skimmed milk.This time the cartons looked a bit squashed, but maybe that is just the new shape as every carton in the shop was the same.
When I opened the first one this morning it was the new type of cap where it is fixed to the carton by a little tie and inside, instead of the usual pull off plastic seal, there was a foil seal which was broken.
I have looked in about half of the milk cartons we bought and all the foil seals were either broken, or missing altogether.
We rang Lidl and the customer service guy said he thought these must be faulty and we should take them back to the shop, which we will do.
Has anyone else had these new packs and are yours faulty, or has anyone had any cartons with the foil seals intact? If they were intact what do you do with them? Just push them into the milk, or how do you get them out?
Thanks

is it a new plastic cap type that has prongs which automatically tear the foil as you twist it off?

Years ago when I worked in a supermarket I had a customer come in raging about how all the cartons of juice she’d bought were faulty because all the foils were pierced, she just hadn’t noticed the new cap type or read the carton which informed her this would happen on twisting the cap.

Hello NottmArt,
I have noted exactly the same thing with Dairy Manor long life milk cartons. I think that the crushed appearance around the cap is a manufacturing issue which should be addressed because it is detracts from the appearance of the product and is aesthetically undesirable. Having examined the screw cap carefully I agree with WishICouldWillow that it does have two cutting blades which are designed to disrupt the inner foil seal. I prefer the old cartons where it was necessary to remove the inner seal by pulling a tab. What is important is that you are dealing with a sterile product and is important to minimise the time that the carton is left open. Replace the cap as soon as you have poured out the milk that you need, to prevent the ingress of microorganisms that are always floating in the air or being shed from your body. Stay safe and healthy.
