Abstract
A receptacle for a carrying a vessel therein is provided with abutments that engage against the vessel itself or against a shield that receives the vessel to prevent relative motion of the vessel with respect to the receptacle as a torque is applied to the cap of the vessel.
Claims8
A container for carrying a vessel having a radionuclide therein, the vessel having a body portion with a cap threadedly secured thereto, the body portion having a plurality of planar walls that terminate in a predetermined number of corners, the cap having an exterior surface having a predetermined contour, the container comprising:
- a receptacle having a base and a sidewall, the sidewall having an edge thereon, the sidewall and the base cooperating to define a volume therein, the base having an array of abutments extending from the base into the volume, each abutment having a holding edge thereon engaging against the exterior of the planar walls of a vessel when the vessel is received within the volume, the holding edges of adjacent abutments engaging against each of the planar walls of the vessel in the vicinity of the corners thereof;
- and
- a lid having an open and a closed end and an exterior and interior surface thereon, the lid being detachably connectable at its open end to the edge of the sidewall, the exterior surface of the closed end of the lid having a recess contoured to conform to the contour of the cap so that the lid, when inverted, may be insertable onto the cap and the cap receivable into the recess therein such that a torque applied to the lid is transmitted into the cap to threadedly loosen the cap from the body of the vessel, the abutments engaging the exterior of the body of the vessel to prevent rotation of the body of the vessel within the receptacle as the torque is applied to the lid.
A shielded container for carrying a vessel having a radionuclide therein, the vessel having a body portion with a cap threadedly secured thereto, the cap having an exterior surface having a predetermined contour, the container comprising:
- a receptacle having a base and a sidewall, the sidewall having an edge thereon, the sidewall and the base cooperating to define a volume therein, the base having an array of abutments extending from the base into the volume, each abutment having a holding edge thereon,
- a shield having an exterior surface defined by a plurality of planar walls and having an opening therein, the opening being shaped to conform to the exterior surface of the vessel, the shield being received snugly within the receptacle with the exterior surface of each of the planar walls of the shield being engaged by one of the abutments;
- and
- a lid having an open and a closed end and an exterior and interior surface thereon, the lid being detachably connectable at its open end to the edge of the sidewall, the exterior surface of the closed end of the lid having a recess contoured to conform to the contour of the cap so that the lid, when inverted, may be insertable onto the cap and the cap receivable into the recess therein such that a torque applied to the lid is transmitted into the cap as the vessel is received in the opening in the shield to threadedly loosen the cap from the body of the vessel, the abutments engaging the shield to prevent rotation of the body of the vessel with respect to the shield and receptacle as the torque is applied to the lid.
