A sample receiving device for releasably storing a composition, comprising: (a) a lid comprising a reservoir for retaining said composition, and a pierceable barrier , sealing said composition within said reservoir ; and (b) a funnel comprising a first open end for receiving a sample and a channel extending from said first open end to a second open end, said first open end configured for closure by said lid and for receiving said composition, and said second open end being releasably or permanently attachable to a sample receptacle , wherein said funnel comprises one or more cutting ribs for cutting said pierceable barrier during closure of the lid , characterized in that the one or more cutting ribs cut said pierceable barrier without a twisting action during closure of the lid , wherein the lid is attached to the funnel via a living hinge; wherein said one or more cutting ribs extend upwardly toward said first open end of the funnel and each of said one or more cutting ribs comprises a sharp upper edge , wherein at least one of said one or more cutting ribs comprises a piercing tooth projecting beyond said sharp upper edge of said at least one of said one or more cutting ribs ; wherein the piercing tooth contacts and pierces said pierceable barrier to form a puncture, and said sharp upper edge of said at least one of said one or more cutting ribs propagates a cut in said pierceable barrier from the puncture made by said piercing tooth . (a) a lid comprising a reservoir for retaining said composition, and a pierceable barrier , sealing said composition within said reservoir ; and (b) a funnel comprising a first open end for receiving a sample and a channel extending from said first open end to a second open end, said first open end configured for closure by said lid and for receiving said composition, and said second open end being releasably or permanently attachable to a sample receptacle , wherein said funnel comprises one or more cutting ribs for cutting said pierceable barrier during closure of the lid , characterized in that the one or more cutting ribs cut said pierceable barrier without a twisting action during closure of the lid , wherein the lid is attached to the funnel via a living hinge; wherein said one or more cutting ribs extend upwardly toward said first open end of the funnel and each of said one or more cutting ribs comprises a sharp upper edge , wherein at least one of said one or more cutting ribs comprises a piercing tooth projecting beyond said sharp upper edge of said at least one of said one or more cutting ribs ; wherein the piercing tooth contacts and pierces said pierceable barrier to form a puncture, and said sharp upper edge of said at least one of said one or more cutting ribs propagates a cut in said pierceable barrier from the puncture made by said piercing tooth . the one or more cutting ribs cut said pierceable barrier without a twisting action during closure of the lid , wherein the lid is attached to the funnel via a living hinge; wherein said one or more cutting ribs extend upwardly toward said first open end of the funnel and each of said one or more cutting ribs comprises a sharp upper edge , wherein at least one of said one or more cutting ribs comprises a piercing tooth projecting beyond said sharp upper edge of said at least one of said one or more cutting ribs ; wherein the piercing tooth contacts and pierces said pierceable barrier to form a puncture, and said sharp upper edge of said at least one of said one or more cutting ribs propagates a cut in said pierceable barrier from the puncture made by said piercing tooth . <EOS>
