Total Claims: 6
Claim 1
Independent Claim 171 words
An ampoule for containing a liquid product and able to be filled under vacuum, said ampoule comprising a container body having a neck with an opening and a stopper of plastic material force-fitted on said body to close said opening, said stopper having a weakened zone enabling a portion of said stopper to be easily torn away to open an orifice of sufficient area to allow the product contained in said ampoule to run out normally, said stopper defining a capillary vacuum-filling orifice to be closed after filling, said stopper including a projecting nose which constitutes said portion of said stopper which is torn away, said nose being of conical shape and having a tearable base, the portion of said ampoule which remains in place after tearing off said nose including an internal collar included in the neck of the container with a central opening of smaller diameter than said base of said nose so that said nose, after removal and reversal, is introducible into said opening to re-stopper said ampoule.
