Abstract

A pressurized appliance comprising, a tank, suitable for receiving liquid contents, a cover, suitable for sealing the tank in a closed position, said cover comprising a sampling tip, said tip comprising a cannula capable of being in contact with the contents when the cover is in the closed position, the sampling tip comprising at least one sealable orifice making it possible, when the cover is in its closed position and said orifice is a through-orifice, to ensure a pressure equilibrium between the inside of the cannula and the inside of the tank, and when the cover is in its closed position and said orifice is sealed, to sample the contents via the cannula.

First claim

1 . A pressurized appliance comprising:
a tank, suitable for receiving liquid contents, a cover, suitable for sealing the tank in a closed position, said cover comprising a sampling tip, said tip comprising:
a cannula capable of being in contact with the contents when the cover is in the closed position,
and at least one sealable orifice making it possible, when the cover is in its closed position and said orifice is a through-orifice, to ensure a pressure equilibrium between the inside of the cannula and the inside of the tank, and when the cover is in its closed position and said orifice is sealed, to sample the contents via the cannula,

wherein it comprises a removable sampler, said removable sampler sealing the sealable orifice when the latter is positioned and held in the sampling tip.

2 . The pressurized appliance as claimed in claim 1 , wherein the removable sampler is suitable for cooperating with a suction means such as a peristaltic pump.

3 . The pressurized appliance as claimed in claim 1 , wherein the sampling tip comprises several sealable orifices, distributed radially over the part of the tip extending into the tank.

4 . The pressurized appliance as claimed in claim 1 , wherein the sampling tip comprises an intermediate part that is removable relative to the cover.

5 . The pressurized appliance as claimed in claim 4 , wherein the intermediate part is suitable for cooperating with a tightening means, said part extending into the tank when the cover is in the closed position.

6 . The pressurized appliance as claimed in claim 1 , comprising a cap that cooperates with the sampling tip, wherein the orifices are through-orifices and the sampling tip is sealed when the cap is positioned and held on the sampling tip.

7 . The pressurized appliance as claimed in claim 1 , wherein the cannula comprises a beveled end.

8 . The pressurized appliance as claimed in claim 1 , wherein the cannula is made of two connectable parts, at least one of the parts being flexible.

9 . The pressurized appliance as claimed in claim 1 , wherein the tank has a curved bottom.

10 . The pressurized appliance as claimed in claim 1 , wherein the tank is suitable for receiving a bucket in order to contain the liquid contents, the cannula extending into the bucket when the cover is in the closed position.

11 . A method comprising preparing a culture medium with the pressurized appliance as claimed in claim 1 .
