Abstract
A cartridge () containing a dose () of at least one substance, for example, ground coffee, for preparing a liquid product using liquid and/or steam introduced into the cartridge () comprises a body () with a bottom wall () and a cover () for closing the body () of the cartridge () in a position opposite to the bottom wall (). The cover () is coupled to the body () via a coupling element, such as, for example, the mouth part () of the body or a lock ring () that undergoes shape variation under the action of said liquid and/or steam, thus causing release of the coupling between the cover () and the body () of the cartridge (). The coupling element () comprises, for example, compostable material that can undergo post-crystallization under the action of heat, which has not been subjected to post-crystallization in the cartridge () prior to use.
