Definitions

  • the invention relates to piercable closures for containers, particularly sterile or sterilisable containers for samples, usually blood, that may require pathological test and analysis.
  • a closure in the form of a dished cap equipped with securement means relative to a sample container, say as a push-fit or via screw- threading of its side walling, and with the dished portion of the cap having an aperture clear through but closed by an added membrane of a non-elastomeric material, usually different from the cap, more readily pierced than any practical integral thinning of the cap material.
  • a membrane that is between 0.02 mm and 0.50 mm in thickness and of a material and a specific thickness selected to afford practical combination of piercability, robustness and resistance to moisture and water vapour penetration or transmission.
  • a relatively thick material in the above range usually, of course, has advantages, at least in robustness, compared with very thin and easily pierced membranes even where such are not subject to porosity or being left with holes therethrough, though the use of such membranes in practising this invention is not ruled out entirely.
  • One suitable membrane material is aluminium foil, which we prefer to mount upon a washer-like base apertured to register with the cap aperture when fitted, and generally to form what we call a "wad".
  • Another aspect of this invention concerns a wad for insertion as a seal into an apertured cap, the wad including an annular washer-like base member apertured to register with the cap aperture and having secured thereto an aperture- closing membrane that is readily piercable.
  • the whole wad is such as to be clamped between a container mouth edge and the cap itself about the aperture of the latter.
  • the membrane shall extend sufficiently, preferably fully, across the cap dishing. Then the membrane will either be engaged directly by all of the mouth edge of the container, or subjected to compressive clamping by the latter engaging on the base of the wad, depending on the attitude of the wad in the cap.
  • the membrane should afford a liquid-tight seal and act as a suitable barrier against bacteria and water vapour. It is also desirable that the seal should not be subject to adherence problems when, as is required for blood samples, the container must be opened for addition of blood, usually to a suitable medium already in the container (e.g. sodium citrate), and reclosed/sealed pending subsequent piercing to sample for test purposes, usually in a pipette in a pathology laboratory.
  • a suitable medium already in the container e.g. sodium citrate
  • At least wads hereof can often be interference fits to the caps. However, wherever desired or required such wads, even membranes only, may be fixed into the cap using a suitable cement or adhesive, say of hot melt or impact types.
  • hot melt adhesive leads us to another aspect hereof where an apertured cap is sealed simply with readily piercable solidified material, such as hot melt adhesive, in the aperture regardless of specific other leak proof features for the cap.
  • a container 10 is shown screw- fitted with a dished cap 12 via internal threading of the side wall 14 of the cap mating at 16 with exterior threading of a neck portion 18 of the container below edge 22 of its mouth.
  • the dished end portion 26 of the cap 12 has a e.g. centrally located aperture 28 clear through its thickness. Clamped between the interior of cap end 26, all about its aperture 28, and the container mouth edge 22 is a wad 30.
  • the wad 30 comprises an annular washer-like base member 32, centrally apertured at 34 in register with the cap end aperture 28, and a membrane 36 covering that aperture 34.
  • the membrane 36 comprises aluminium foil affixed to base member 32 either directly by a suitable adhesive as indicated for an expanded polythene base, or via a paper backing (not shown, but often advisable for certain wad materials, such as woodpulp board).
  • the base member 32 is engaged all round by the container mouth edge 22 for desired sealing, in fact abuts substantially entirely to the periphery of the inner surface of the cap end portion 26.
  • the wad needs only to be pressed into place, usually as an interference fit (push-fit), though it could be adheringly secured by a suitable adhesive or cement if preferred or required.
  • the membrane 36 is shown extending entirely across the base member 32, including its aperture, and is subjected to edge compression through the base by action of the container mouth edge 22 to reduce risk of delimination. It is feasible to use the wad inverted so that the membrane contacts the container mouth edge, so long as a satisfactory seal results, and paper-backing of aluminium or other foil can assist both securement and sealing.
  • the complete wad is made as a unit, i.e. the base member 32 and the membrane 36 affixed securely together. Any suitable adhesive or cement can be used or they may simply be hot-pressed together where waxed backing paper is used for the membrane foil.
  • the base member 32 of the wad 30 assists in assuring compressive obtainment of a readily broken and reattained liquid seal.
  • Unpreferred, but practical, possibilities arise by way of relying only upon a membrane, perhaps preferably backed, secured directly to the inner surface of the cap, maybe even not fully coextensive therewith, nor sealing to the container mouth edge, or the latter and the cap are mutually formed to seal together without interposition of a barrier foil or film.
  • Adhesives based on synthetic resins are suitable, for example polyvinyl acetate. Heat sensitive adhesives are preferred for adhering membranes to wad bases. At least hot melt adhesives may even allow membranes to be dispensed with, relying instead simply on a plug of settable but readily pierced material on the cap aperture.
  • Lamination of foil to a paper backing if used is conveniently by way of synthetic latex adhesives applied hot or cold, but normally using heat in the laminating process to accelerate curing.
