摘要
The subject of the invention is a storage and dispensing (distribution) tube (C) for a product, for example a water-containing product which may be flavoured or perfumed, comprising a dispensing head which is fixed onto a flexible multilayer skirt, this skirt essentially containing an intermediate polymer layer (20) which has a barrier effect with respect to oxygen and flavours or perfumes, the said layer being sensitive to humidity, as well as, on each face of this intermediate layer, one or more polymer layers (1; 12,14,10) based on polyolefins, all of the said layers being bonded together in a continuous manner, characterised in that the set of layers situated on the inner face of the said intermediate layer having a barrier effect (1,21) has a total thickness of between 40 and 150 micrometres, so as better to conserve the flavour or the perfume which is or may be contained therein. This tube preferably includes one or two means which render the dispensing of the contained product easier and more complete. It applies to the industries for packaging products which are, for example, liquid, creamy or pasty. IMAGE
