I had to walk to the local shop to get some emergency milk, and on the way back, I suddenly wondered why the colours for full fat, medium and skimmed milk are blue, green and red respectively?

I would have thought yellow for full fat, cream colour for medium and, I don't know, clear for skimmed - would have been more logical and more closely reflect the colours of the actual milk. Too subtle maybe?

What about red, amber and green for full, medium and skimmed - at least that would use the traffic light system for fat content and sort of make sense.

But the present colours; where did they come from ?

Perhaps colours chosen to help those afflicted with colour blindness, just a thought. Dave W

Hi Dave W, I was wondering the same thing and had look on the web, but couldn't find anything definitive.

Regards Nick.

I'm not sure it helps the colour blind. I'm Red/Green colour blind as are something like 20% of the male population. Many are the times I've ben told off by other half for getting Green not Red or vice versa. We now stick to just one version - Red. Which 9 times out of 10 I now get correct.

Well after Colin’s comment then perhaps not for those who are colourblind. Dave W

Just read on the internet that Waitrose are scrapping red and green lids on their milk containers because they can’t be recycled for food grade packaging, in future they will use clear plastic that can be recycled for food grade packaging, well we live and learn. Dave W

Yellow (gold) is for jersey milk, the old gold top when I was a kid and in the mornings if you were not up early the blue tits and robins would have the top of the cream. Ah the good old days, Noel.

I've no idea where the current colour code originates, but it differs from the colours used on the foil caps on glass milk bottles which were set out in the Milk and Dairies (Milk Bottle Caps) (Colour) Regulations 1973

Glass bottles were permitted to remain in pint measures (legally 568ml) because they were a pre-existing reusable container. Although I just said I had no idea about the current plastic bottle colour codes, I would guess that they were harmonised for the single market, whilst glass bottle foil remained with the 1973 colours.

Hi, my parents couldn't afford gold tops, but the occasional bird would have a go at our silver tops. I can remember at school once in the winter of 1962, a lot of the 1/3 pints of milk we use to have, had frozen so much that the frozen milk was poking out of the bottles by about 1/2" or so and the silver tops were just sitting on the top of the frozen milk. The teachers had to put them near a radiator to thaw them out before we could have them and I think I can remember it all made a little mess on the floor that they had to clean up afterwards.

Regards Nick.

As for capacity, some shops sell the plastic milk containers in multiples of pints and some in litres. The imperial ones are bigger.

Our local Waitrose went over to the uncoloured caps for about two weeks, and now they are all coloured again... Figure that out!

I've noticed that the caps on plastic bottles are different in different parts of the country, so there is presumably no general regulation that applies to them.

The plastic for the top is diferent from the bottle in plastic sets. If you can separate the coloured top from the bottle it can be recycled easily and there are machines at the recycling plant able to blow the coloured tops out with air blast. The plastic in the top has to be diferent to be able to stay on to the more flexible bottle plastic and there is a test of dropping a full bottle from a certain height to test the bottle lid couple. I was involved in the manufacture of the tooling for the lids and blow moulding of the bottles but quite a while ago now before I retired. There was a standard which said that the two parts should be easily separated for recycling but I can't remember if it was a supliers standard or EU etc.

It would appear from the above information, that it is better to leave the tops off the plastic milk containers when putting them in the re-cycling bin and chuck the tops in loose.

Around East Anglia, the coloured tops are recycled separately, (By a different company in a different town, and even county! ) whereas the bottles go in the council recycling bin.

You have always been asked to take tops off containers, whether metal or plastic. Apart from the colour they are often a different recycling category typically 2 for the container and 5 fro the lid (not milk bottles though).

Hi, our council asks for the lids to be kept on, on all types of bottle.

Regards Nick.
