  • Patent number: 5464097
    Abstract: A package for liquid concentrates comprises an outer container (1) and an inner water-soluble or water-dispersible envelope (3) containing the concentrate. The container (1) has a shock absorbing base formed by joining a base-part (9) to the main body-part (8) with an S-shaped or corrugated strip (10), thus providing a flexible connection allowing relative movement between the base-part (9) and main body-part (8). The container (1) is sealed with a removable foil lid (2) and is tapered towards its bottom and has a wide neck to allow easy exit of the envelope (3).
