Definitions

  • the invention concerns a waste disposal container for use in the handling of infected, fluid-laden waste.
  • Waste of this kind is produced in large quantities in hospitals, medical and welfare services centres, laboratories and similar institutions, and include such articles as e.g. infected throwaway protective clothing, wound dressings and bedding as also syringes, test or cultivation tubes, infusion-liquid containers and other receptacles filled with e.g. blood or urine, dialysis filters and several other kinds of often fluid-laden materials. Because the waste as a rule is infected it must not be deposited directly on a municipal dump, not even if hermatically sealed in an enclosure. Before such a deposition the waste disposal container must be subjected to a steam disinfec ⁇ tion process in a sterilizer.
  • a conventional type of package used for these purposes is a corrugated cardboard box including an interior plastic bag containing the waste.
  • the above mentioned fluid containers are either entirely open or sealed in some simple manner.
  • liquid consequently seeps out of the con ⁇ tainer and collects at the bottom of the plastic bag.
  • This liquid amount is heated by means of steam during the process essentially on the external face of the plastic bag.
  • condensate generates in large quantities, depending on the high specific heat capacity of liquids. For example, heating of one kilo of liquid from ambient temperature to the disinfection temperature produces approximately 160 g of condensate.
  • the condensate collects at the bottom of the corrugated cardboard box.
  • the subject invention provides a waste container solving the problems outlined above.
  • the characteristic features of this container appear from the appended claims.
  • Fig. 1 is an exploded view of the waste container and Fig. 2 is a vertical cross-sectional view through the waste container in assembled condition.
  • the package in accordance with the invention consists of a parallelepiped box 1 made from corrugated cardboard, a tray insertable into the box 1 and also made from corrugated cardboard, and a thermostable plastic bag 3 in which waste of the above-recited nature may be collected.
  • the tray 2 has plastic-coated interior side walls 4 and a plastic-coated bottom 5 and flaps 6, 7, 8, 9 that may be folded inwards and which in a manner known per se form liquid-tight corner sections in the tray 2.
  • a pad 10 or the like is intended to be deposited in accordance with the invention.
  • This pad 10 or the like consists of a material having a high liquid- absorbing capability, and it consists e.g. of cellulose fluff, thus forming an absorbant layer.
  • the tray 2 When the container is to be put in condition to receive waste material the tray 2 is positioned on the bottom of the box 1 , the pad 10 is placed on the bottom of the tray 2 and the bag 3 is forced down into the box 1 and the tray 2, into contact with the pad 10.
  • the box 1 At its upper part the box 1 is formed with a couple of flaps 13, 14 which are folded down into contact with two opposite external faces of the box 1 , whereafter the uppermost portion 1 1 of the bag 3 is placed around the mouth portion of the box 1.
  • the folded-over portion 1 1 of the bag 3 protects the box 1 , preventing liquid from waste of the above- mentioned nature to penetrate between the inner walls of the box 1 and the tray 2.
  • the waste disposal container thus completed is positioned inside a sterilizer chamber which is then closed.
  • the disinfection process is preceded by evacuation of the chamber. During this pro- cess, air is sucked out of the package.
  • the bag 3 is provided circum- ferentially with perforations 15 extending in a line some distance below the closure portion 11. Thus, air is evacuated also from inside the bag 3.
  • steam is admitted into the chamber alternatingly with renewed evacuation thereof, followed by steam admission and so on which is repeated a couple of times.
  • condensate collects essentially at the bottom part on the external face of the bag 3. Should the bag 3 contain comparatively large amounts of liquid the quantitiy of condensate liquid may be comparatively large.
  • the waste disposal container in accordance with the invention thus offers the considerable advantage of never having to be opened on its way from being closed at the site of collection of the waste to the site of deposition while at the same time it provides access for steam into all parts of its interior, thus allowing satisfactory disinfec ⁇ tion of the waste material.
  • the tray 2 may be provided with flaps 6, 7, 8, 9 of different configuration but still capable of forming liquid- tight corners.
  • the absorbant layer 10 could consist for instance of a powder or of compacted peat which like the cellulose material possesses extremely good liquid absorbant capacities.
