Abstract: The invention relates to a method for making a rivet (R), of the type comprising, by deformation of the material of a substantially cylindrical metal segment, the operations of preforming a milled head (100) at the end of a rod (200), characterised in that it comprises, by deformation of the material (cold stamping) the following operations: creating a portion with a lower diameter (210) from the free end; creating a substantially cylindrical hollow core (220) for forming a tubular portion; preforming the hollow core (220) as a truncated cone; performing the lower diameter outer surface as a truncated cone. The invention also relates to the rivet obtained by said method.

Abstract: A vial containing liquid contents constructed so as to permit transfer of its contents to a syringe without the use of a needle with the syringe. One embodiment employs rotation of a cap to align openings avoiding the use of a needle. In another embodiment, there is provided mounted within apparatus located on the mouth of the vial a needle which is built in to the apparatus. The syringe engages the needle which is then depressed to puncture the cork sealing the vial, the vial is then inverted, and the contents drained into the syringe. The needle is withdrawn thereby resealing the contents of the vial, and the needle remains with the vial.
