The present invention generally relates to a sample receiving device for releasably storing a substance. The sample receiving device includes a lid having a reservoir for retaining the substance, and a pierceable barrier sealing the substance within the reservoir; and b) a funnel for receiving a sample and configured for closure by the lid. The funnel is configured for releasable attachment to a sample receptacle such that a sample can be provided to the funnel and travel through the channel in the funnel into the sample receptacle. Further, the funnel includes one or more cutting ribs for cutting the pierceable barrier such that upon cutting of the pierceable barrier the substance is released from the reservoir, flows through the channel in the funnel and into the sample receptacle to be mixed with the sample. The present invention also provides a kit for collecting and storing biomolecules.

The device of claim 5, wherein said wall has an outer edge and said barrier is sealingly attached to said outer edge so as to cover said reservoir. 7. The device of claim 6, wherein said wall nests within the first open end of said funnel to form a fluid tight seal when the device is in a closed condition. 8. The device of claim 1, wherein the channel has an opening that is offset from the centre of said funnel and the funnel additionally includes an interior surface that is sloped downward from an interior edge toward the channel opening, and wherein said interior sloped surface defines a flow path for said composition following release of said composition from said reservoir when said barrier is cut by said one or more cutting ribs. 9. The device of claim 1, 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. 10. The device of claim 9, wherein at least one of said one or more cutting ribs comprises a piercing tooth projecting beyond said sharp upper edge. 11. The device of claim 1, which additionally comprises a tensioning means for maintaining tension on said pierceable barrier during cutting of said barrier. 12. The device of claim 1, wherein the device includes a single cutting rib. 13. The device of claim 1, wherein the device includes two cutting ribs. 14. The device of claim 13, wherein said cutting ribs are arranged opposite one another on either side of a vertical plane extending through the length of said funnel. 15. The device of claim 11, wherein said tensioning means comprises one or more tension ribs that extend upwardly toward said first open end of the funnel and each of said one or more tension ribs comprises a blunt or curved upper edge. 16. The device of claim 15, wherein each of said one or more tension ribs is rigid or resilient. 17. The device of claim 15 which comprises a single cutting rib having a piercing tooth and a single tension rib, wherein said cutting rib and tension rib are arranged in a curved “V” shape forming a pocket region such that the piercing tooth is at the apex of the “V”, and wherein the wide end of the “V” is adjacent the opening of the channel. 18. The device of claim 17, wherein the cutting rib extends further toward the first open end of said funnel than the tensioning rib. 19. The device of claim 1, wherein the funnel additionally comprises an expelling means for expelling the sample from a sample-containing absorbent device into the channel of said funnel. 20. The device of claim 1, wherein the reservoir is sized to accommodate about 0.1 ml to about 10.0 ml of said first substance. 21. The device of claim 1, which additionally comprises a removable lid guard. 22. A sample receiving device for releasably storing a composition, comprising: (a) a lid comprising: (i) a wall defining an outer perimeter of a reservoir for retaining said composition;(ii) a pierceable barrier sealingly attached to an outer edge of said wall so as to seal said composition within said reservoir; and(iii) an inner rib extending from an inner surface of the lid into the reservoir and on a plane approximately perpendicular to the plane of the barrier, wherein an outer edge of the inner rib is directly proximal to or in contact with an inner surface of the barrier; andb) a funnel having a first open end for receiving a sample and configured for closure by said lid, and a second open end for releasable or permanent attachment to a sample receptacle, wherein the lid is attached to the funnel via a living hinge, and wherein said funnel comprises: (i) a channel extending from said first open end to said second open end;(ii) one or more cutting ribs for cutting said pierceable barrier without a twisting action during closure of the lid, each of said cutting ribs having 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; and(iii) one or more tension ribs that extend upwardly toward said first open end of the funnel, wherein each of said one or more tension ribs comprises a blunt or curved upper edge. 23.
