Section: claims

1. A pig for transporting a container of biohazardous material, wherein the container comprises a bottle and a bottle closure, the pig comprising:a body comprising a compartment dimensioned to receive the container;a cap attachable to the body for closing the compartment thereby to shieldingly contain the biohazardous material in the container, the cap comprising:a collar sealingly engageable with the body and having an opening therethrough in communication with the compartment thereby to provide access to the bottle closure;a cap closure sealingly engageable within the opening of the collar to sealingly close the opening and cause the bottle closure to be gripped within the cap,wherein when the collar is disengaged from the body while the cap closure is engaged within the opening of the collar, the container remains gripped within the cap,wherein when the cap closure is released from the opening of the collar, the container is released from the cap. 2. The pig of claim 1, wherein the cap closure comprises an annulus projecting into the opening for causing the bottle closure to be gripped within the cap. 3. The pig of claim 2, further comprising a compression member dimensioned to be positioned intermediate the bottle closure and the annulus, the compression member being compressed against the bottle closure by the annulus while the cap closure is sealingly engaged within the opening of the collar. 4. The pig of claim 3, wherein the compression member comprises:a flange;spaced apart fingers supported by the flange and forming a circle complementary to an inner wall of the annulus, the spaced apart fingers resiliently compressible inwardly against the bottle closure by compressive engagement of the annulus. 5. The pig of claim 4, wherein the compression member comprises lugs extending from the flange and dimensioned to project into complementary bores in a lower edge of the collar. 6. The pig of claim 5, wherein the compression member is formed of a thermoplastic. 7. The pig of claim 1, further comprising a handle assembly encapsulating the body and comprising a handle that is extendable and rotatable through a plurality of orientations with respect to the body. 8. The pig of claim 7, wherein the handle assembly comprises:an upper collar associated with an upper end of the body;a lower collar associated with a lower end of the body;at least two struts extending between the upper collar and the lower collar thereby to maintain the upper collar and the lower collar in a fixed spaced relationship,the handle associated with and extending from the struts. 9. The pig of claim 8, wherein the handle comprises:two elongate arms depending from opposite ends of a cross member, each of the arms having an elongate channel therethrough,wherein each elongate channel is dimensioned to rotate and slide with respect to a respective knob being passed through each channel into a respective aperture in a corresponding strut while the knob is untightened to its respective aperture, wherein the handle is fixed in position with respect to the body while at least one of the knobs is tightened within its respective aperture. 10. The pig of claim 8, wherein at least the upper collar and the lower collar are formed from a thermoplastic material. 11. A system for transporting and providing access to a biohazardous material, the system comprising:a pig for transporting a container of biohazardous material, wherein the container comprises a bottle and a bottle closure, the pig comprising:a body comprising a compartment dimensioned to receive the container;a cap attachable to the body for closing the compartment thereby to shieldingly contain the biohazardous material in the container, the cap comprising:a collar sealingly engageable with the body and having an opening therethrough in communication with the compartment thereby to provide access to the bottle closure;a cap closure sealingly engageable within the opening of the collar to sealingly close the opening and cause the bottle closure to be gripped within the cap,wherein when the collar is disengaged from the body while the cap closure is engaged within the opening of the collar, the container remains gripped within the cap;wherein when the cap closure is released from the opening of the collar, the container is released from the cap; andan insert sealingly engageable within the opening of the collar while the cap closure is removed, the insert comprising an injection port extending fully therethrough in axial alignment with the compartment thereby to guide insertion of a syringe centrally through the container closure and into the container. 12. The system of claim 11, wherein the injection port is cylindrical and has a single diameter extending fully through the insert. 13. The system of claim 11, wherein the injection port has an upper portion extending partway through the insert and having a first diameter, and a lower portion extending from the upper portion through the rest of the insert and having a second diameter, the second diameter being smaller than the first diameter. 14. A compression member for insertion into a pig for transporting a container of biohazardous materials, the compression member comprising:a flange; andspaced apart fingers supported by the flange and together forming a circle, the fingers each having a substantially vertical component connected to and extending upwards from the flange and a substantially horizontal component connected to, and extending inwards towards the middle of the circle from, an end of the substantially vertical component that is distal from the flange, wherein spaced apart fingers are resiliently compressible inwardly towards the middle of the circle against the container by compressive engagement of a complementary annulus of the pig into which the compression member is dimensioned to be inserted. 15. The compression member of claim 14, wherein the compression member comprises lugs extending from the flange for frictional retention within the complementary annulus. 16. The compression member of claim 14 wherein the flange and fingers are formed of a thermoplastic material. 17. The compression member of claim 14, further comprising a web extending between each pair of adjacent fingers. 18. The compression member of claim 17, wherein the flange and fingers are formed from a first material and each web is formed from a second material that is less rigid than the first material. 19. The compression member of claim 18, wherein the first material is a thermoplastic and the second material is silicone. 20. The compression member of claim 14, wherein the flange comprises a sloped edge about its periphery for snap retention within the complementary annulus.
