Bottle with an outer casing

摘要

The flask (1) has a rigid one-piece jacket (2) made of transparent material and fixed to the flask. The jacket forms a cylindrical container which is open at the top and allows the flask to be installed from the top during assembly. The jacket may permanently or detachably connected to the bottle. The jacket has an outer circumferential surface (2b1) and an inner circumferential surface (2b2), and the flask has an outer circumferential surface (1a1), whereby at least two and preferably all three surfaces have graphic elements (6-8) to achieve a 3D effect.
