Cartridge without an inadmissible overpressure

A method for filling an ink and/or solvent cartridge for a printer, such a cartridge including a volume delimited by a semi-rigid or deformable pocket, and being provided with an aperture, and having a given maximum capacity VCmax, defined at a balanced pressure between the inside and outside of the cartridge, in which method:

• a partial filling of said cartridge is conducted, by introducing therein a volume of liquid comprising an ink and/or a volatile solvent, which leaves a gas volume in the cartridge;
• the sum of this volume of liquid and of said gas volume, being equal to a filling volume VC, which remains lower than said maximum capacity VCmax in the whole temperature range from 10° C. to 35° C. and for a 1 bar pressure;
• the aperture of said cartridge is hermetically sealed.

A device for filling an ink and/or solvent cartridge for a printer, such a cartridge including at least one semi-rigid or deformable volume, and being provided with an aperture, and having a given maximum capacity VCmax, defined at a balanced pressure between the inside and outside of the cartridge, this device including:

• a housing for accommodating at least one part of said semi-rigid or deformable volume;
• means for applying a pressure on said semi-rigid volume;
• means for introducing into said cartridge a volume of liquid, comprising an ink and/or a volatile solvent, such that the sum of this volume of liquid and of the gas volume held in said cartridge, is lower than said maximum capacity VCmax, in the whole temperature range between 10° C. and 35° C. and for a 1 bar pressure
