A disposable cartridge (1) for use in a beverage maker comprises a container (10) for containing at least one beverage ingredient and a connector (20) for establishing a connection between the cartridge (1) and a beverage maker. The connector (20) comprises a hollow needle member (22) having a blunt end (23) for piercing a portion (11) of a wall (12) of the container (10), wherein the needle member (22) extends inside a dome-shaped portion (13) of the container wall (12). Furthermore, the connector (20) is movably arranged with respect to the container (10). During operation, an impacting force is exerted on the needle member (22), as a result of which the connector (20) is moved with respect to the container (10), in a direction towards the container (10), and the pierceable portion (11) of the container wall (12) is pierced by the end (23) of the needle member (22). After the piercing process has taken place, the content of the container (10) is retrievable through the needle member (22).
