The package is sealed by a top sealing film. The body has a column at its lower end integral with the centre of the bottom. The top sealing film is such that a base liquid feed lance can passed through the film and engage with the upper end of the column to dispense base liquid into the channel of the column. The column has apertures. The bottom has a multitude of filter holes or discharge openings, and a flexible portion around the column. A bottom sealing film is provided which breaks upon relative motion of the column to the lower operative position, creating one or more outflow openings in the film for outflow of the product from the package.
