System for hygienic suction of liquid in tin cans by means of a straw

摘要

System formed by weakening lines 3 which delimit a zone to be raised, with the inclusion of a ring 1, rivet 4 supporting said ring and lug 5 supporting the straw, as well as the straw 6 with its bellows part 7. The hygienic drawbacks involved in contact between the lips and the tin can whose contents are to be drunk, the insertion of the small tongue delimited by the actual cuts 2 into the liquid, and the spilling-over of the liquid via the channel in the lid are resolved (thus preventing a liquid/dirt mixture).
