1. A self-sealing closure for sealing a receptacle, said closure comprising a lid having a depressed area and at least one orifice within the depressed area, a shutter matching said orifice, means for holding the shutter against said orifice, and means rotating within a plane perpendicular to the central axis of said receptacle and lid for pushing the shutter away from said orifice in a direction substantially orthogonal to the plane of said orifice, wherein: (a) said shutter is normally in a closed position in which the passage of fluid through it is prevented, (b) said shutter can be moved from its closed position to an open position by the application of an external force applied along the perimeter of the shutter within a plane perpendicular to the central axis of the shutter, (c) when said external force ceases to be applied to the shutter, the shutter spontaneously returns to its closed position, (d) said closure is comprised of means for limiting the extent to which said shutter may be pushed away from said orifice in a direction substantially orthogonal to the plane of said orifice, (e) said lid is comprised of a first, horizontally-extending guide slot which is integrally formed as part of said lid, (f) said shutter is comprised of at least two different means for removably attaching said shutter to said lid, wherein at least one of said means comprises a first projection integrally formed with and extending downwardly from said shutter, (g) said shutter is comprised of a second projection integrally formed with and extending downwarldy from said shutter, and (h) said lid is comprised of at least two adjacent, integrally formed, upwardly extending projections defining a slot therebetween. 2. The closure as recited in claim 1, wherein said closure consists of said lid and said shutter. 3. The closure as recited in claim 1, wherein said closure has a cross-sectional shape which is substantially circular. 4. The closure as recited in claim 1, wherein said first projection is comprised of a hook. 5. The closure as recited in claim 1, wherein said lid is comprised of an upwardly-extending finger. 6. The closure as recited in claim 1, wherein said shutter is comprised of at least one orifice. 7. The closure as recited in claim 1, wherein said second projection is an elastic body. 8. The closure as recited in claim 1, wherein said lid is comprised of at least two dimples on one surface of said lid. 9. The closure as recited in claim 8, wherein said lid is comprised of at least four dimples on one surface of said lid. 10. A receptacle comprised of a self-sealing closure, wherein said closure comprises a lid having a depressed area and at least one orifice within the depressed area, a shutter matching said orifice, means for holding the shutter against said orifice, and means rotating within a plane perpendicular to the central axis of said receptacle and lid for pushing the shutter away from said orifice in a direction substantially orthogonal to the plane of said orifice, and wherein: (a) said shutter is normally in a closed position in which the passage of fluid through it is prevented, (b) said shutter can be moved from its closed position to an open position by the application of an external force applied along the perimeter of the shutter within a plane perpendicular to the central axis of the shutter, (c) when said external force ceases to be applied to the shutter, the shutter spontaneously returns to its closed position, (d) said closure is comprised of means for limiting the extent to which said shutter may be pushed away from said orifice in a direction substantially orthogonal to the plane of said orifice, (e) said lid is comprised of a first, horizontally-extending guide slot which is integrally formed as part of said lid, (f) said shutter is comprised of at least two different means for removably attaching said shutter to said lid, wherein at least one of said means comprises a first projection integrally formed with and extending downwardly from said shutter, (g) said shutter is comprised of a second projection integrally formed with and extending downwarldy from said shutter, and (h) said lid is comprised of at least two adjacent, integrally formed, upwardly extending projections defining a slot therebetween. 11. The receptacle as recited in claim 10, wherein said closure consists of said lid and said shutter. 12. The receptacle as recited in claim 10, wherein said closure has a cross-sectional shape which is substantially circular. 13. The receptacle as recited in claim 10, wherein said first projection is comprised of a hook. 14. The receptacle as recited in claim 10, wherein said lid is comprised of an upwardly-extending finger. 15. The receptacle as recited in claim 10, wherein said shutter is comprised of at least one orifice. 16. The receptacle as recited in claim 10, wherein said second projection is an elastic body. 17. The receptacle as recited in claim 10, wherein said lid is comprised of at least two dimples on one surface of said lid. 18. The receptacle as recited in claim 10, wherein said lid is comprised of at least four dimples on one surface of said lid.
