A spike for facilitating the introduction of liquid under pressure into a container containing a substance is provided which includes an elongate spike shaft having a spike side wall, a longitudinal axis, a distal end and a proximally located end portion, where the distal end has a sharp, pointed tip. An introduction channel is located within the spike shaft for receiving liquid into the container where a portion of the introduction channel is angled to cause liquid to travel out of the introduction channel in a direction non- parallel to the longitudinal axis of the spike shaft. An extraction channel may be included within the spike shaft for removing liquid from the container, where the extraction channel extends through the elongate spike shaft towards the proximally located end portion.

L'invention se rapporte à un perforateur facilitant l'introduction d'un liquide sous pression dans un récipient contenant une substance. Ce perforateur comporte un axe de perforateur allongé équipé d'une paroi latérale de perforateur, un axe longitudinal, une extrémité distale et une partie d'extrémité située à côté, l'extrémité distale présentant une pointe pointue et tranchante. Un canal d'introduction se trouve à l'intérieur de l'axe de perforateur afin de faire passer le liquide jusque dans le récipient, une partie du canal d'introduction formant un angle de manière à ce que le liquide sorte du canal d'introduction dans un sens non parallèle à l'axe longitudinal de l'axe de perforateur. Un canal d'extraction peut être également introduit dans l'axe de perforateur afin d'ôter le liquide du récipient, ce canal d'extraction s'étendant à travers l'axe de perforateur allongé vers la partie d'extrémité située à côté.
