Method for hygienically protecting drink containers (12) provided with a tear-off sealing tongue which remains attached to the head portion (11) of the container when the latter is opened. The head portion is coated by simple dipping into a non-toxic, biodegradable liquid that is capable of setting in a few seconds, thereby forming an adhering film (10) that coats at least that portion of the head portion (11) of the container in which the drink delivery orifice (14) is provided. The solution according to the invention is particularly simple, economic and effective to implement, convenient in its use, and complying with applying environmental regulations. |
