Abstract A dually sealable, non-leaking vial for shipping liquid radioactive materials, particularly sterile radioactive materials, and other sterile liquid materials in which the mouth of the vial, as shipped, is sealed by a needle pierceable septum seal and in which a threaded cap is located and held over the septum seal and mouth with the threads thereby held out of engagement with mating threads on the vial by the septum seal. However, upon removal of the septum seal after shipment, the threads of the cap mate with the threads of the vial whereby the cap can be removably threaded tightly over the mouth to seal it. The capped and septum-sealed loaded vial is placed in a heat shrinkable plastic envelope having a bottom end wall and an upstanding cylindrical wall of greater height than the capped, septum-sealed vial and of lesser thickness than the bottom end wall and the envelope is heat shrunk circumferentially, tightly and sealably around the capped septum-sealed vial with the upper part of the envelope being shrunk circumferentially and downwardly tightly over the margin of the upper surface of the cap to securely seal the capped septum-sealed vial.
A sealed vial for shipping radioactive materials comprising in combination a vial having a mouth and a threaded portion, a septum seal sealably but removably secured over said mouth, a threaded cap located over said mouth and septum seal and depending there around, a cylindrical heat shrinkable envelope normally of greater height than said capped septum-sealed vial and closed at its bottom by a bottom wall of greater thickness than the envelope cylinder but open at its top and adapted to snugly receive said capped septum-sealed vial with the open top end thereof extending upwardly beyond said cap and the bottom of the vial resting on the bottom wall of said envelope, said cylindrical wall being heat shrunk sealably and circumferentially around said capped vial with the open upper end portion of said heat shrinkable envelope being heat shrunk inwardly and downwardly and sealably over the marginal portion of the top of said cap to seal the capped vial and prevent accidental removal of the screw cap.

A sealed vial for shipping radioactive materials comprising in combination a vial having a mouth and a threaded portion, a septum seal sealably but removably secured over said mouth, a threaded cap located over said mouth and septum seal and depending there around, a cylindrical heat shrinkable envelope normally of greater height than said capped septum-sealed vial and closed at its bottom by a bottom wall of greater thickness than the envelope cylinder but open at its top and adapted to snugly receive said capped septum-sealed vial with the open top end thereof extending upwardly beyond said cap and the bottom of the vial resting on the bottom wall of said envelope, said cylindrical wall being heat shrunk sealably and circumferentially around said capped vial with the open upper end portion of said heat shrinkable envelope being heat shrunk inwardly and downwardly and sealably over the marginal portion of the top of said cap to seal the capped vial and prevent accidental removal of the screw cap.
Claim 3
Dependent Claim
67 words
A vial according to claim 1, said envelope having a circumferential line of weakness extending around the circumference thereof between the portion thereof surrounding said cap and the portion thereof surrounding an enlarged body portion, whereby upon turning of said cap relative to said vial, the heat shrunk envelope breaks at said line of weakness to thereby permit removal of the cap to expose said septum seal.
Claim 4
Dependent Claim
60 words
A vial according to claim 2, the top portion of said envelope having a pair of parallel lines of weakness extending longitudinally from said circumferential line of weakness to the upper edge of said envelope to permit removal from the cap of the broken portion of the envelope surrounding said cap after said circumferential line of weakness has been broken.
Claim 5
Dependent Claim
123 words
A vial according to claim 1, said vial having an enlarged body portion and a reduced neck portion extending upwardly into an enlarged lip forming said mouth and downwardly into said threaded portion, the threads of which are external, said cap having a depending wall depending around said septum seal, said mouth and said neck, said depending wall having internal threads held out of mating engagement with said external threads by said septum seal when said septum seal is located over said mouth but being located in mating engagement with said external threads when said septum seal is removed from said mouth, whereby said cap is adapted to be threaded over said mouth to seal said mouth when said septum seal is removed.
