<p>Coated bottle comprising a bottle made of a fragile material, provided with an external coating of either (a) a thermoplastic elastomeric unhydrogenated block copolymer having the general configuration A?B - A)n or A-B-?B-A)n wherein A represents a non-elastomeric polymer block of a monoalkenyl or mono-alkenylidene aromatic hydrocarbon, B represents an elastomeric polymer block of an aliphatic conjugated diene hydrocarbon, and n represents an integer in the range of from 1 to 5, or (b) a completely or partially hydrogenated derivative of the block copolymer, the thermoplastic elastomeric block copolymer having a tensile strength of at least 50 kgs/cm2 and an elongation at break of at least 400%. The coating of thermoplastic rubber is intended for use in only one round-trip of the bottle.</p> |
