<p>A closable container device for fluid or mass, adapted for automatic serial production and comprising entirely reusable, recoverable and/or decomposable components. Its main parts are: a container or bottle (1, 71) having a wide neck portion (4, 74), a cap (3, 73, 111) and a fluid tight inner liner (2, 72) made of thermoplastic and preferably heat shrinkable and UV decomposable material. The container (1, 71) itself is not fluid tight but has vent hose (12, 14) and acts more like an outer reusable packing unit around its inner liner. Initially said inner liner (72) preferably is sealed and folded within the cap (73, 111) and is brought into the container in a bottlery during its serial production. The container is designed to be reused a large number of times before destruction and recovering, while the inner liner may be destructed after use only once, or it may be reused after cleaning and inspection. The lower part of the cap is provided with a lock or support ring (76, 117) which may have a protruding collar. The container device is usable both for liquids and mass in powder form and will satisfy the most severe environmental demands.</p> |
