Dispensing of a substance

摘要

The invention proposes to dispense a substance from a container (1) filled with a single portion of a substance. The container (1) comprises a preformed deformable body defining a filling cavity which body has an opening and an integral planar circumferential rim surrounding said opening. The opening is closed by a cover sheet which is sealed to the circumferential rim by a circumferential sealing seam (10). The sealing seam (10) has a predetermined zone where the sealing seam breaks upon pressurizing the content of the container. The circumferential rim is provided with one or more positioning protrusions (601,602) for positioning the container (1) in a dispensing apparatus.
