<p>1. An assembly of a cap (1) and a receptacle (4) intended for corrosive or volatile products, the receptacle having a rim (9) intended to receive a sealing cover (5) having a sealable layer intended to co-operate with the cap to form a fluidtight seal by an induction process, the cap having on its inner surface at least one annular shoulder (1) which, in the closed position of the receptacle, maintains the sealing cover (5) on an outer peripheral zone (10) directly adjoining the rim (9) so as to allow the sealing of said sealing cover (5), characterized in that the afore-mentioned shoulder (7) extends axially from the inner surface of the cap (1), and in that the peripheral zone (10) of the receptacle is of frustoconical shape so as to allow sealing to take place on said peripheral zone (10), the mouth of the receptacle thus being in the form of a bevel so as to enable the cover (5) to be applied tightly on to the peripheral zone (10), thereby precluding the seepage of the aforementioned corrosive or volative products.</p> |
