- the liquid container (2) can consist of a steel which is coated or lined on the inside with a polyolefin.
- a container made of a chromium-nickel steel with a coating of the polyolefin adhering to the entire inner surface of the container is preferred.
- the polyolefin is preferably a fluorinated polyolefin, particularly preferably polytetraflourethylene (PTFE), polyvinylidene difluoride (PVDF) or a tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer (PFA).
- the liquid container (2) made of pure aluminum is preferred since, after the container has been cleaned, hydrogen peroxide solutions with a low content of peroxide stabilizer can also be safely transported in the container.
- the liquid container (2) has an internal volume of 65 to 500 I, preferably from 65 to 250 I.
- the liquid container preferably has a cylindrical shape, particularly preferably the shape of an upright cylinder (6) with a curved bottom (7) and cover (8).
- the base (7) and cover (8) are preferably welded to the cylinder (6).
- the wall thickness of the liquid container is preferably chosen so that the liquid container can withstand a pressure difference between the interior of the container and the atmosphere surrounding the container of at least 2.5 bar, preferably at least 1.5 bar, as well as a fall of the transport container from a height of 2 m.
- a pressure equalization device (3) and a pressure relief valve (4) are arranged on the top of the liquid container (2).

- a filter made of a hydrophobic polymer, e.g. PTFE, with a small pore size can be used for the same purpose, in which a differential pressure of more than 200 mbar is required for the passage of liquid hydrogen peroxide through the filter material.
- Suitable pressure equalization devices (3) are known from storage tanks for hydrogen peroxide and larger transport tanks for hydrogen peroxide and are commercially available, e.g. from PEROLO under the name "H202 Breather”.
- a pressure relief valve (4) in the sense of the invention is a valve that only allows gas passage at a certain overpressure of more than 0.1 bar inside the container and remains closed at a lower pressure difference or a negative pressure in the liquid container.
- the pressure relief valve (4) is preferably designed so that when a limit value for the excess pressure in the liquid container (2) is exceeded in relation to the surrounding atmosphere in the range from 0.1 to 2.5 bar, particularly preferably from 0.5 to 2 bar, in particular from 1.5 bar, opens.
- the pressure relief valve (4) is preferably designed in such a way that it automatically closes again when the limit value for the overpressure is undershot. Pressure relief valves (4) which open and close by means of a spring mechanism which is moved by the overpressure in the liquid container (2) and which do not require any auxiliary energy are preferred.
- the pressure relief valve (4) is preferably designed in such a way that, in the open state, it releases a through opening with a cross section of at least 3 cm 2 , preferably from 4 to 200 cm 2.
- the pressure relief valve (4) enables the oxygen and water vapor formed in the process to escape in the event of rapid decomposition of hydrogen peroxide in the liquid container (2) and, in the event of such decomposition, prevents a pressure increase in the liquid container to pressures that could lead to the container bursting.
- Suitable pressure relief valves (4) are known from storage tanks for hydrogen peroxide and larger transport tanks for hydrogen peroxide and are commercially available, for example from PEROLO under the name “YAK VX safety relief valve”.
- the liquid container (2) also has at least one closable opening (5) of the liquid container (2) for filling with hydrogen peroxide and / or removing hydrogen peroxide.
- the closable opening (5) is preferably arranged on the upper side of the liquid container (2) and is preferably closed with a lid, which preferably closes in a gas-tight manner.
- the cover can be fastened over the opening, for example by screwing or with a clamping ring.
- the closable opening is preferably designed with a flange to which a fitting that closes the opening can be attached for the removal of hydrogen peroxide.
- a fitting preferably comprises a dip tube that extends close to the bottom of the liquid container (2) and through which hydrogen peroxide can be pumped out of the transport container (19).
