At some point in the past, the small cylindrical tubs of milk were an innovation. They allowed for instant milk-ification of tea and coffee on trains, in restaurants, and so on. Some people I know even keep some in their handbag, just in case.
However, I feel that they ceased to be an innovation a
long time ago - around about the time when the first was opened, spilling the contents all over someone's pants. This milk spillage was then exarcebated by the attempts to catch milk, which failed miserably and ended up with a hot mug of tea being spilt on someone's private parts. Someone was not amused.
I suspect that innovation of this product stopped because the tub was 'sufficient'. People bought it and it became perceived wisdom that milk had to be opened in such a haphazardly way.
I say 'Boo!' to this. Why should milk come in miniature cartons that resemble thimbles, only to be perpetually spilt?
I propose a slender, pipette-like disposable container with a twist-off plastic cap. Hold it by the neck, with opening facing up. Break off the cap, tilt the pipette to pour out milk.
