A cartridge for obtaining a beverage by injecting into the cartridge a pressurized fluid, comprising a box-like body, which accommodates a substance from which it is possible to extract the beverage, and which accommodates on its inside an insert which separates the substance from a bottom wall of the box-like body, forming an interspace. The insert comprises an orifice for the passage of the beverage toward the interspace, whereas the bottom wall comprises a region which can be pierced to obtain an opening for the outflow of the beverage. In the interspace there is a basin which is arranged laterally with respect to the pierceable region in order to accumulate the beverage received directly from the orifice and make it flow out of the opening by overflowing.
