Said envelope consists by at least 50% by weight, preferably at least 70% by weight, more preferably by at least 90% by weight and especially by 100% by weight of water-insoluble organic oils that are liquid at 20°C and of waxes that can be kneaded at 20°C, that melt above 40°C without being decomposited and that are converted to a molten, low-viscous state between 50 and 90°C.
