Definitions

  • This invention relates to containers and has a particularly useful but not exclusive use in relation to containers for the shipment of radiolabelled and other hazardous materials. These containers in some instances carry only a few microlitres.
  • radiolabelled compounds such as 32P-, 33P- and 35S-labelled nucleotides
  • the compounds have hitherto been transported from the site of manufacture to the end user at low temperatures (for example packed in dry ice at a temperature of -70°C to - 80°C) to minimise radiochemical decomposition and this has resulted in bulky packaging which is inconvenient for disposal by users.
  • a vessel for transporting radioactive sources in which the vessel consists of an outer casing having a cavity within which a separate container for the radioactive source is located.
  • a flexible sling in the form of a sleeve is provided within the outer casing for supporting the inner separate container.
  • the lid of the outer casing seals against the sling and provides a seal in addition to the separate closure of the inner container.
  • a container defining a cavity with an opening, to a neck and having a cap releasably secured on the neck covering the opening and a liner disposed within the cavity and including an end flange by which the liner is supported from the upper end of the neck characterised in that the liner further includes a liquid containing cavity at an inner end of the liner, an annular shoulder facing towards the end flange and a sealing element comprising a head adapted to abut the annular shoulder and to form a liquid-tight seal therewith and a stem extending towards the end flange, an outer end of the stem being arranged for engagement with an underside of the cap such that when the cap is secured on the neck the head of the sealing element is held in sealing engagement with the annular shoulder.
  • Figures 1 and 2 respectively show in sectional elevation two containers according to the invention.
  • the container is shown removably disposed in a two-part inner casing 10a, 10b which is in turn disposed in a multi-part outer casing 11a, 11b incorporating lead shielding.
  • the container has a base part 12 formed from a transparent plastics material such as acrylic and providing an internal cavity 16, and a screw-cap 13 engaged on a screw-threaded collar portion 14 of the neck of the container. Spaced above the collar 14 the neck has a radially thickened end-part 15.
  • the cavity 16 of the container is of generally cylindrical form with a rounded inner end, and a translucent liner 17 in the form of a v-vial made from a plastics material such as polypropylene is suspended by an end flange 18 thereof within the cavity.
  • the end flange 18 of the liner rests on the top of the neck and has a down-turned skirt 19 which fits against the radially outer surface of the thickened end part 15 of the neck and which has an inturned lip 20 below the part 15.
  • the end flange has an integral upstanding annular land 21 which is abutted by a gasket 22 contained within the cap 13.
  • the upper portions of the liner 17 are disposed close to the wall of the recess, but the lower portions of the liner are of reduced diameter and are spaced away from the wall of the recess.
  • the liner has spaced above its rounded lower or inner end an annular internal shoulder 23 facing towards the neck and a sealing element 25 extending along the liner has a head 26 which abuts the shoulder to form a seal.
  • the shoulder 23 is substantially conical and the contacting surface of the head is part-spherical.
  • the stem 27 of the sealing element is of much smaller diameter than the liner except at its outer end where it has an increased diameter portion 28 which is a loose fit against the internal surface of the liner and which provides an annular shoulder 29 at its inner end.
  • the sealing element has a further annular shoulder 30 disposed inwardly of the shoulder 29 and facing towards the head 26. The upper end of the portion 28 abuts the gasket 22.
  • An elongate conical recess 31 is formed in the upper end of the portion 28, and, when the cap 13 has been removed, is frictionally engageable by the correspondingly conical end of a rod-like implement e.g. a pipette tip (not shown) to enable the sealing element 25 to be lifted out of the cavity.
  • a rod-like implement e.g. a pipette tip (not shown)
  • FIG. 2 The construction illustrated in Figure 2 is generally similar to that shown in Figure 1 and corresponding components are indicated by corresponding reference numerals.
  • the sealing element 25 is attached to the underside of the cap 13.
  • no gasket is provided on the underside of the cap, and the upper end of the sealing element 25 extends upward beyond the end flange 18 and has an end portion 32 the outer diameter of which is an interference fit within the side wall of the cap.
  • the upper end of the sealing element may be bonded to the underside of the cap.
  • the underside of the enlarged end portion 28 of the sealing element abuts the sealing land 21 on the end flange of the liner.
  • the sealing element 26 can be placed in a centrifuge tube to enable liquid remaining on the sealing element to be collected in the bottom of the centrifuge tube.
  • the liquid to be transported is safely sealed in the bottom end of the cavity in the liner by the head 26 of the sealing element, and access to the liquid by means of a pipette for example is opened when the cap 13 and the sealing element 25 have been removed.
  • the colourless transparency of the container and the colourless translucency of the liner enable a colour coding of the liquid to be used to identify the liquid in the container, if desired.
  • the container can be used without the inner and outer casings 10a, 10b, 11a and 11b.
  • the containers particularly described above provide a suitable means of transporting small volumes of potentially hazardous liquid materials in a container which has a much larger cavity. This large cavity provides greater convenience of operation.
  • the ratio of liquid to total cavity volume can be typically in the range 1:2 to 1:100.
