CLOSURE DEVICE FOR A FLUID PRODUCT RESERVOIR

摘要

The invention relates to a closure device (100; 200; 300), for fitting to an opening (41) of a fluid product reservoir (4), said device being embodied in a monobloc form by injection /moulding of plastic material and comprising a fixing body (110; 210; 310) for cooperation with the opening on the reservoir to produce a sealed fixing, a distribution duct (120; 220; 320), forming an outlet passage (121; 221; 321) for the fluid product contained within the reservoir, said duct forming a distribution opening (122; 222; 322), a closing body (13; 23; 33), for sealing said duct, said closing body being connected to the distribution duct (120; 220; 320) by means of at least one link of material (132; 232; 332), designed to break on the first withdrawal of the closing body. The invention is characterised in that said closing body (130; 23; 33) comprises a sealing part (131; 231; 234; 331; 334), said sealing part, before sealing, leaves the distribution opening free and, after sealing, closes the distribution opening (122; 222; 322) in a sealed manner.
