Abstract

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 removabley 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.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 117 words
A sealed vial for shipping liquid radioactive materials comprising in combination a vial having a mouth and threaded portion below said mouth, a needle-pierceable septum seal removably and sealably secured over said mouth, a sealing cap located over said septum seal and mouth and having threads held out of mating engagement with said threads of said vial by the thickness of said septum seal when said septum seal is located over said mouth, said cap threads being located in mating engagement with said threads of said vial when said septum seal is removed from said mouth whereby said sealing cap may be removably threaded over said mouth to seal the mouth when said septum seal is removed.
Claim 2
Dependent Claim 117 words
A sealed vial for shipping liquid radioactive materials comprising in combination a vial having a mouth and threaded portion below said mouth, a needle-pierceable septum seal removably and sealably secured over said mouth, a sealing cap located over said septum seal and mouth and having threads held out of mating engagement with said threads of said vial by the thickness of said septum seal when said septum seal is located over said mouth, said cap threads being located in mating engagement with said threads of said vial when said septum seal is removed from said mouth whereby said sealing cap may be removably threaded over said mouth to seal the mouth when said septum seal is removed.
Claim 3
Dependent Claim 101 words
A vial according to claim 1, said vial comprising an enlarged body portion and a reduced neck portion extending upwardly into a enlarged lip forming said mouth and downwardly into said threaded portion, the threads of whcih are external, said cap comprising an end wall and a cylindrical wall depending therefrom around said septum seal, mouth and reduced neck, said cap threads being located on the internal surface of said depending wall and being held above said external threads of said vial by said neck and septum seal to hold said internal threads out of mating engagement with said external threads.
Claim 4
Dependent Claim 52 words
A vial according to claim 2, the inner surface of said end wall of said cap having a sealing disc secured thereto which is urged into sealing engagement with said lip when said cap is threaded over said mouth to seal the mouth when the septum seal is removed from said mouth.
Claim 5
Dependent Claim 29 words
A vial according to claim 2, the outer surface of thE bottom wall of said vial being dished in at its center with the outer margin thereof being corrugated.
Claim 6
Dependent Claim 47 words
A vial according to claim 1, the interior of said vial being conical shaped at its bottom to concentrate the radioactive material in the vial, said mouth being formed by an enlarged lip having an upstanding ridge for cooperating with the septum seal to increase sealing effect.
Claim 7
Dependent Claim 109 words
A vial according to claim 1, said septum seal comprising a pierceable rubbery disc secured to said lip by a securing member having an apertured upper end wall located over the top of said disc and a cylindrical end wall depending downwardly around the peripheries of said disc and lip and thence under said lip to urge said disc sealably against said lip, said end wall of said securing member over said disc being cut to form a tab for pulling said securing member and disc off said mouth of said vial to thereby remove the septum seal from said mouth whereby said cap can be sealably threaded thereon.
