Abstract
A substance for preparation of a beverage contained in a sealed flexible sachet is extracted with a device which has two members which are configured to each form a cavity which is substantially one-half of a chamber so that upon being tightened together for holding the sachet for extraction of the substance, the sachet is provided with a desired shape and is perforated to enable injection of water for extraction of the substance. Upon perforation, water is injected which deforms a surface against raised portions of one of the members and then tears the sachet to allow flow of beverage from the sachet through holes of the member containing the raised portions.
