De oplossing is door er met de achterkant van het koffielepeltje een gaatje in te prikken. Doet mijn man al jaren.

Well, the base of the problem, 'spilling when opening the milk cup',
lies not with its packaging. The problem is the to low airpressure in
the cabin of all airplanes. This pressure is held lower because of the
airplane body strain differences. Normally, the maximum pressure differential between the cabin and the outside air is 7.58 psi (5255 kPa). If the cabin were maintained at sea level pressurization and then flown to 35,000 feet (10.7 km) or more, the pressurization differential would be greater than 9 psi (60 kPa) and the structural life of the airplane would be limited.

Solution for the milk cup and of course all fluid packaging for airplane consumption is to process packaging in a vacuum packaging machine environment, so about minus 9 PSI(60kPa)

During my youth in the 50's, 60's and 70's my parents my brother and I flew very regularly to and from The netherlands to Australia, New Ginea, Japan and so on. Back then I allready officially planted on paper this idea to the Royal Dutch Airlines being the KLM. Never heard of it again, no reply, nothing.

greets,
